A family based tailored counselling to increase
non-exercise physical activity in adults with a
sedentary job and physical activity in their young
children: design and methods of a year-long
randomized controlled trial
Taija Finni1*, Arja Sääkslahti2, Arto Laukkanen1, Arto Pesola1 and Sarianna Sipilä3
Abstract
Background: Epidemiological evidence suggests that decrease in sedentary behaviour is beneficial for health. This
family based randomized controlled trial examines whether face-to-face delivered counselling is effective in
reducing sedentary time and improving health in adults and increasing moderate-to-vigorous activities in children.
Methods: The families are randomized after balancing socioeconomic and environmental factors in the Jyväskylä
region, Finland. Inclusion criteria are: healthy men and women with children 3-8 years old, and having an
occupation where they self-reportedly sit more than 50% of their work time and children in all-day day-care in
kindergarten or in the first grade in primary school. Exclusion criteria are: body mass index > 35 kg/m2, self-
reported chronic, long-term diseases, families with pregnant mother at baseline and children with disorders
delaying motor development.
From both adults and children accelerometer data is collected five times a year in one week periods. In addition,
fasting blood samples for whole blood count and serum metabonomics, and diurnal heart rate variability for 3
days are assessed at baseline, 3, 6, 9, and 12 months follow-up from adults. Quadriceps and hamstring muscle
activities providing detailed information on muscle inactivity will be used to realize the maximum potential effect
of the intervention. Fundamental motor skills from children and body composition from adults will be measured at
baseline, and at 6 and 12 months follow-up. Questionnaires of family-influence-model, health and physical activity,
and dietary records are assessed. After the baseline measurements the intervention group will receive tailored
counselling targeted to decrease sitting time by focusing on commute and work time. The counselling regarding
leisure time is especially targeted to encourage toward family physical activities such as visiting playgrounds and
non-built environments, where children can get diversified stimulation for play and practice fundamental of motor
skills. The counselling will be reinforced during the first 6 months followed by a 6-month maintenance period.
Discussion: If shown to be effective, this unique family based intervention to improve lifestyle behaviours in both
adults and children can provide translational model for community use. This study can also provide knowledge
whether the lifestyle changes are transformed into relevant biomarkers and self-reported health.

The document summarizes research on the effectiveness of prevention programs in addressing childhood obesity. It reviews studies that evaluated after-school programs focused on nutrition education, physical activity, or both. The review found some programs resulted in reductions in BMI and improved healthy eating, but longer-term interventions are still needed to drive meaningful changes. The review analyzed six studies varying in sample size, location, intervention duration and focus (physical activity only vs. both physical activity and nutrition). Overall the evidence does not clearly support or refute after-school programs' ability to prevent obesity, but some positive outcomes were seen.
This document summarizes research from over 50 studies evaluating interventions to increase physical activity levels across different age groups and settings. The research shows mixed results, with some interventions like tailored walking programs and changes to the built environment effectively increasing activity, while other school-based programs had little impact. Overall, the review finds that there are no single solutions and a range of factors must be addressed to help populations become more active.

The prevalence of childhood obesity has been increasing rapidly and there is general consensus that good nutritional practices and physical activity should be encouraged as early as possible in life. The aim of this study was to describe and to compare the current lifestyle and dietary pattern of normal weight (NW) and overweight + obese (OW+OB) male adolescents who are physically active.
Methods: This observational and retrospective study was based on clinical records analysis of male adolescents aged 11-18 years who had undergone a medical evaluation at a Medical Sport Centre (Pavia, Italy) during 2009, and had filled in a self-administered life style questionnaire.
Results: The results showed that out of 1423 clinical records 23.0% of subjects were OW, 5.4% OB and 71.6% NW. We invited all the overweight and obese subjects to participate in the study, 308 of them (75.8%) agreed. Then we randomly enrolled an equivalent number of NW participants (n=308) in the medical evaluation at the sports center with similar characteristics as for socio-economic status, physical activity and age for a whole sample of 616 subjects. We handled them a validated lifestyle questionnaire. The questionnaire analysis was used to compare OW+OB and NW participants, as far as eating habits, sedentary activities and time spent in sports. All the subjects frequently skipped breakfast, did not consume fruit and vegetables daily and had a high soft drinks intake. Inverse correlations were found between weight and physical activity (p=0.01). Sedentary activities were preferred by about 25% and 66 % of the NW and OW+OB groups respectively. The percentage of smokers was similar within the two groups (14%).
Conclusions: Adolescents eating habits are incorrect, despite BMI and sports practice. Sports practice seems contributing to lower spare time physical inactivity, but does not improve eating habits. Public health interventions should focus on the reinforcement of leisure time physical activity, besides nutrition education and behavioral education programs in order to prevent obesity in the adulthood.
Physical Activity Level Analyses and Chronic-Degenerative Disease Risks In Do...IJERDJOURNAL
Abstract:- It is of common belief that physical activity can restore damages caused to people's health due to the stressful everyday work routine. The energy expenditure on physical activities is directly related to the frequency, duration and intensity of human movements developed on many tasks. Thus, the main objective of this paper was to evaluate this energy consumption in public school teachers from the city of Horizonte, Ceara, discussing about degenerative chronic disease risks. 30 teachers, 9 men and 21 women within the age of 25 to 59 years old, were evaluated. Their Body Mass Index (BMI) was calculated in order to classify them as normal, overweight and obese. As an instrument, the long version of the International Physical Activity Questionnarie (IPAQ) was used, once it is more recommended to national prevalence studies due to the possibility of international comparison. This instrument contains several questions related to frequency (days per week) and duration (time per day) spent on moderate and vigorous physical activities and walking. The questionnarie also captures the energy expenditure in METs, in order to classify the selected individuals according to intensity: “sedentary” (< 1,5 METs), “low” (1,5 < METs < 3,0), “moderate” (3,9 < METs < 5,9) and “high” (≥ 6,0 METs). These analyses were performed using the Epi Info™ program, which used descriptive statistics. The results showed that the teachers present a good level of physical activity with 46,67% classified as high, 40% as moderate and 13,13% as low. The individuals also presented significant degree of overweight and obesity, 43% and 34% respectively, and only 23% within the acceptable weight range. Therefore, it could be concluded that, among the modifiable risk factors, the physical activity and the body mass control play important roles when it comes to chronic-degenerative disease prevention

The Physical Activity Guidelines for Americans (PAG) provides science-based guidelines to help Americans aged 6 and older improve their health through appropriate physical activity. The PAG was first released in 2008 and is part of Healthy People 2020. Healthy People 2020 guidelines recommend that children and adolescents get at least 60 minutes of moderate physical activity per week, while adults aim for 150 minutes of moderate exercise or 75 minutes of vigorous activity per week. However, over 80% of US adults and adolescents do not meet these physical activity guidelines.
1) Childhood obesity is a significant public health problem, affecting about 1 in 5 children in the US. Effective prevention and management requires a combination of primordial, primary, and secondary prevention strategies focusing on behavior change.
2) Key interventions include educating parents and children about nutrition, physical activity, and health risks; monitoring behaviors through logging; and setting goals with self-monitoring and positive reinforcement of healthy behaviors.
3) Findings will be disseminated through posters, flyers, brochures and briefs to provide concise information to clinicians, parents, and children. Implementing a comprehensive prevention strategy in clinical practice could substantially improve quality of life for obese children.

PHYSICAL ACTIVITY AND SELF-EFFICACY 2
The Relationship between Physical Activity and Self-Efficacy in Schools
Abstract
Few studies have examined the relationship between physical activities and health outcomes among adolescents. The majority of the adult population knows much about health-risk behaviours of adolescents, and knows less about their health-promoting behaviours. The purpose of the study was to determine the relationship between physical activity levels and self-efficacy among adolescents.
Introduction
According to Start Active, regular physical activity associates with benefits for physical and mental health (as cited in Roberts et al, 2015). Studies have indicated that health life traits and styles have an impact on lifelong health and life quality. Childhood poor diet and physical inactivity have been risk factors for a multitude of chronic health condition in adulthood (Matthews et al, 2015). According to the Centers for Disease Control and Prevention for children, only 42% of children and 8% of adolescents achieve current recommended physical activity.
Most students studying in Hoca Ahment Yesevi University were hound to have health issues emanating from lack of physical exercise and personal fitness programs (Ozkan, 2015). Up to 70 per cent of university students are reported as not participating in regular free-time physical activity or exercise (Haase et al, 2004, as cited in Roberts et al, 2014). Simon et al (2015) mentioned that majority of the adult population fails to achieve recommended daily exercise, 30-minutes moderate intensity exercise. When physical activity is conducted regularly as the researchers found out, it is likely to improve the physical fitness of the students and generally of people and therefore contributing heavily to better healthy life styles. Achieving daily exercise was shown to promote better sleep quality and higher psychological functioning in adolescents (Kalak et al, 2012, as cited in Rew et al, 2015).
Styles and activities that promote the health of humans increase their chances of wellbeing and therefore promote healthy living. In achieving well-being in health, there must be a mentioned engagement in activities which are likely to enhance the same such as proper exercises and fitness methods. Health promotion takes quite a multidimensional structure, that is, intellectual, mental, physical and social and therefore a number of behaviours which are meant at promoting behaviours are identified by health professionals and other researchers. These behaviours include life appreciation, stress management, health responsibility, social support, exercise and better nutrition. Therefore a general conclusion is arrived at that physical activity and exercise have an impact on the quality of human life and can actually aid its improveme.

The article examines the effects of fasting during Ramadan on metabolic rate and exercise performance. Researchers studied 16 young male soccer players who continued training during Ramadan. They measured factors like body composition, hydration, sleep, diet, heart rate, and blood lactate before, during, and after Ramadan. The study found that fasting led to increased rates of dehydration, hormonal changes, reduced muscle performance, increased lipid oxidation, and lowered resting metabolic rate. These energy changes, dehydration, sleep disruption, and circadian rhythm shifts impacted physical performance during Ramadan fasting.

Evidence Based Practice and Policy ReportsA Structured Pee.docxturveycharlyn
This document describes a structured peer-mentoring method for promoting physical activity among adolescents in school settings. The method trains high school students to mentor younger peers and deliver a physical activity curriculum. Research shows peer mentoring improves social support and self-efficacy which can lead to sustained behavior change. The authors developed a peer-mentoring program over several studies that improved physical activity levels and health outcomes in students. The summary outlines key steps to implementing a structured peer-mentoring program in schools, including obtaining a curriculum, securing infrastructure support, and selecting peer mentors with strong interpersonal skills.
The leading causes of obesity in children are unhealthy food choices, lack of physical activity, and family eating habits. Overweight issues can cause health and social problems for children. Personal development, health and physical education (PDHPE) promotes physical activity, teaches students to value themselves and others, and encourages healthy lifestyle choices through decision making, safety awareness, and understanding the environment. Educating students on these issues through PDHPE can help ensure children grow up with the knowledge and values to lead healthy, active lives.
The document discusses the role of school nurses in promoting student health and wellness. It begins by noting that many children today prioritize screen time over physical activity, exacerbating declining healthy habits. As a result, school nurses must take a leading role in developing and implementing strategies to improve student wellness. The document then defines school nursing as advancing student well-being, success, and lifelong achievement through facilitating positive development. It provides examples of school nurse responsibilities like promoting health, intervening in existing/potential issues, and building student/family self-management. Finally, it states that further research is needed on implementing wellness programs in Chinese schools, as existing research focuses primarily on Western cultures.
This document outlines the author's personal philosophy on health and physical education. It begins by defining physical education as the development of physical fitness and skills through activities, while health education focuses on behaviors that promote wellness. The author discusses the importance of developing health and physical literacy. Five key reasons for incorporating these subjects in schools are then provided: to prevent disease, fight obesity, promote lifelong fitness, prepare children for an active lifestyle, and encourage positive behaviors. The author's primary goal as an educator is to serve as a role model for students and help them establish fitness and nutrition goals through a variety of motivating activities.
How effective are the interventions related to physical activities and nutrit...IOSR Journals
This document reviews 20 intervention studies that focused on physical activity and nutrition through school-based health promotion programs. The interventions ranged from 4 weeks to 3 years, targeted various grade levels, and involved teachers, parents, and other personnel. Most used randomized controlled trial designs. The interventions had diverse components related to physical activity, nutrition education, and changing behaviors. Results were mixed, with some interventions successfully increasing physical activity, nutrition knowledge, and healthy behaviors while others found no significant effects. Limitations included inadequate facilities, lack of long-term follow up, and recommendations focused on more intensive, multi-component interventions.

Abstract
With obesity affecting approximately 12.5 million American youth,
population-level interventions are indicated to help support healthy
behaviors. The purpose of this review is to provide a summary of
population-level intervention strategies and specific intervention exam-
ples that illustrate ways to help prevent and control obesity in children
through improving nutrition and physical activity behaviors. Informa-
tion is summarized within the settings where children live, learn, and
play (early care and education, school, community, health care, home).
Intervention strategies are activities or changes intended to promote
healthful behaviors in children. They were identified from (a) systematic
reviews; (b) evidence- and expert consensus–based recommendations,
guidelines, or standards from nongovernmental or federal agencies;
and finally (c) peer-reviewed synthesis reviews. Intervention examples
illustrate how at least one of the strategies was used in a particular
setting. To identify interventions examples, we considered (a) peer-
reviewed literature as well as (b) additional sources with research-tested
and practice-based initiatives. Researchers and practitioners may use
this review as they set priorities and promote integration across settings
and to find research- and practice-tested intervention examples that can
be replicated in their communities for childhood obesity prevention.

Physical Fitness Involvement Among Young Adults and its Relation to other Act...Vinay Ghosh

Physical activity is one of the major traits among young adults and children. The level of
physical activities among children is found to be directly related to some common diseases like
obesity, cardiovascular diseases, diabetes, high blood pressure, and cancer. This paper consists of
a literature review of various research papers, which have been published in the context of
physical fitness. The various papers have been discussed to prove that physical fitness is directly
related to these diseases.
Peer involvement and skill-sharing was found to contribute to adolescents adopting and maintaining healthy lifestyles. A study evaluated a program called "Share Activities" where student leaders taught their peers about following the USDA's Dietary Guidelines through activities focused on eating breakfast, reducing sugary drinks, increasing fruit/vegetable intake, decreasing junk food, and increasing physical activity. Surveys found most peers were motivated to adopt healthy behaviors after participating and over half reported improving their diets, showing that peer influence can positively impact adolescents' health.
Obesity is quickly becoming one of the most common chronic.docxhopeaustin33688
Obesity is quickly becoming one of the most common chronic diseases among children. These rates have increased at an alarming rate and is a major public health problem because of related physical and psychological comorbidities, including type II diabetes, insulin resistance, metabolic syndrome, cardiovascular disease and mental health disorders. Dramatic increase in the number of overweight and obese children in recent years.
Studies indicate that children's lives may be shortened as a result of this alarming health problem. Estimates state that for any degree of overweight/obesity, younger adults (20-30 years of age) may have greater years of life lost due to obesity than older adults. Childhood obesity has been determined to be an independent risk factor for adult overweight/obesity.
To combat childhood obesity, there is a great need for public health interventions as well as education parents regarding childhood obesity and its consequences. Parents differ on causation of obesity, and differ in focus on nutrition and physical exercise. Many parents in the research do not see obesity as a barrier to physical activity. The parents need to recognize their child as overweight. Prevention is the most effective method for dealing with this growing health concern. The evidence reviewed, confirmed that family-centered interventions were associated with short-term reduction in obesity and improved medical parameters. The goal should be to involve community resources and provider referrals. Nurse Practitioners have a unique role in being the best facilitators to deliver health messages and are able to educate parents and increase awareness about the causes and consequences of childhood obesity.
Parents of young children need to interact with their child's primary healthcare provider for health advice and preventive health information during regularly scheduled physical examinations. It is up to the parents of these young children to combat intervention strategies such as:

AN OVERVIEW OF PHYSICAL ACTIVITY AND HEALTH LITERACY IN ADULT POPULATION WITH...IAEME Publication
This document discusses a study on physical activity and health literacy among adults in Kanyakumari District, India. The study aims to measure satisfaction and health awareness among adults due to the impact of physical activity and health literacy. It involved collecting primary data through questionnaires from 200 respondents. The results showed that most adults maintain lifestyle changes and understand the causes of health conditions. In terms of physical activity, most preferred morning walks or outdoor games. Regarding health literacy, many gained knowledge from media or read about disease prevention. The study found physical activity helped adults access correct health information and choose foods without preservatives.
R E S E A R C H A R T I C L ERelationship Between Frequenc.docxcatheryncouper
This research article examined the relationship between frequency and intensity of physical activity and health behaviors in adolescents. Researchers analyzed survey data from over 800 high school students regarding their physical activity levels and health behaviors over the past 30 days. They found that adolescents who engaged in high levels of vigorous physical activity were less likely to use marijuana or engage in heavy marijuana use, consumed more healthy carbohydrates and fats, used stress management techniques more frequently, and reported better quality of sleep compared to those with low vigorous physical activity. Few differences were seen based on frequency of moderate physical activity. The findings suggest frequent vigorous physical activity in adolescents may reduce risky behaviors and promote healthy behaviors. More research is needed to better understand these relationships.

Qualitative Research Critique and Ethical Considerations
Summary of the Study
The study seeks to evaluate the efficacy of school-based programs in treating and managing overweight and obesity among children. Childhood obesity is increasingly becoming both national and global public health concern that has resulted in increased childhood morbidity and mortality. In particular, childhood obesity has catapulted the increase in health problems such as cardiovascular diseases, diabetes, as well as osteoarthritis later in adulthood (Mahmood et al. 2014). Schools can provide one of the most effective channels through which childhood obesity interventions can be directed. In this respect, policies, procedures, and guidelines have been passed in many nations and states for the implementation of school-based interventions. In the United States, many studies have recommended the utilization of school-based obesity management programs to address the unending crisis of childhood obesity. In light of this concern, this study seeks to investigate the efficacy of school-based interventions in treating and managing childhood obesity. In particular, the study will also assess school methodologies such as incorporation of obesity education into the routine curriculum in minimizing the constantly-increasing cases of obese children population.
Method of Study
The study is also going to use qualitative design in order to examine the perception of children towards school-based obesity management initiatives. Previous studies conducted by Clarke et al. (2015) also sought to investigate the experiences and views of kids who went through school-based obesity management programs. This can help to improve knowledge and understanding of better ways to address the problem of childhood obesity within school settings. In order to provide a comprehensive finding that guides future clinical decision-making, the study will evaluate efficacy of school-based interventions with respect to many key areas. They include cost efficiency of school-based interventions, improvements in physical activities and healthy eating habits following interventions, as well as level of awareness among children on the dangers of childhood obesity and the ways in which it can be averted. Furthermore, effectiveness will be investigated through evaluation of body weight and BMI before and after the introductions of these interventions (Mahmood et al. 2014). Most significantly, cardiovascular fitness and other outcome measures will be investigated. The target population and participants of the study will mainly be school-going children. Both boys and girls with an average age of between 8 and 16 years will be incorporated into the study.
Schools vary in the ways in which they utilize such interventions. For instance, some schools utilize planet health programs that incorpo ...
Levels of Physical Activity Participation of the Staff of Universiti SelangorIOSR Journals
Abstract: This study is carried out to identify the levels of the Universiti Selangor (Unisel) staff’s participation
in physical activities. It aims to investigate the stages of their physical activities to determine whether these
activities are beneficial to them or otherwise. This study is a descriptive survey research of which the data has
been collected via questionnaire from 231 employees of Unisel in Bestari Jaya Campus. Respondents are asked
questions about their physical activities based on the International Physical Activity Questionnaire (IPIQ). The
findings reveal that many members of the staff of the Universiti Selangor practice physical activities as their
way of life. However, the level of their participation in physical activities has not reached a satisfactory level.
The respondents often carry out physical activities, but mostly their participation is still considered within the
range of average to low level. The respondents’ participation in physical activities is influenced by their attitude
which seeks acknowledgment rather than practicing it as a healthy lifestyle. The findings shows that the
employees’ physical activity participation is very high. However, they do not carry out the activities according
to the principles of physical activity domain. This study concludes that there are still many Unisel staff members
that seldom treat physical activities as their everyday routines. The findings show that 106 of the respondents
carry out physical activities at a low level, 49 of the respondents at the medium level and 76 of the respondents
at a high level. The findings are insufficient to establish that the respondents have carried out the best physical
activity practice. The results conclude that these Unisel staff members still need to be guided and educated in
order to ensure that their participation in physical activities becomes a healthy lifestyle that is led by the whole
community.

Evidence Based Practice and Policy ReportsA Structured Pee.docxturveycharlyn
This document describes a structured peer-mentoring method for promoting physical activity among adolescents in school settings. The method trains high school students to mentor younger peers and deliver a physical activity curriculum. Research shows peer mentoring improves social support and self-efficacy which can lead to sustained behavior change. The authors developed a peer-mentoring program over several studies that improved physical activity levels and health outcomes in students. The summary outlines key steps to implementing a structured peer-mentoring program in schools, including obtaining a curriculum, securing infrastructure support, and selecting peer mentors with strong interpersonal skills.
The leading causes of obesity in children are unhealthy food choices, lack of physical activity, and family eating habits. Overweight issues can cause health and social problems for children. Personal development, health and physical education (PDHPE) promotes physical activity, teaches students to value themselves and others, and encourages healthy lifestyle choices through decision making, safety awareness, and understanding the environment. Educating students on these issues through PDHPE can help ensure children grow up with the knowledge and values to lead healthy, active lives.
The document discusses the role of school nurses in promoting student health and wellness. It begins by noting that many children today prioritize screen time over physical activity, exacerbating declining healthy habits. As a result, school nurses must take a leading role in developing and implementing strategies to improve student wellness. The document then defines school nursing as advancing student well-being, success, and lifelong achievement through facilitating positive development. It provides examples of school nurse responsibilities like promoting health, intervening in existing/potential issues, and building student/family self-management. Finally, it states that further research is needed on implementing wellness programs in Chinese schools, as existing research focuses primarily on Western cultures.
This document outlines the author's personal philosophy on health and physical education. It begins by defining physical education as the development of physical fitness and skills through activities, while health education focuses on behaviors that promote wellness. The author discusses the importance of developing health and physical literacy. Five key reasons for incorporating these subjects in schools are then provided: to prevent disease, fight obesity, promote lifelong fitness, prepare children for an active lifestyle, and encourage positive behaviors. The author's primary goal as an educator is to serve as a role model for students and help them establish fitness and nutrition goals through a variety of motivating activities.

This document reviews 20 intervention studies that focused on physical activity and nutrition through school-based health promotion programs. The interventions ranged from 4 weeks to 3 years, targeted various grade levels, and involved teachers, parents, and other personnel. Most used randomized controlled trial designs. The interventions had diverse components related to physical activity, nutrition education, and changing behaviors. Results were mixed, with some interventions successfully increasing physical activity, nutrition knowledge, and healthy behaviors while others found no significant effects. Limitations included inadequate facilities, lack of long-term follow up, and recommendations focused on more intensive, multi-component interventions.

Abstract
With obesity affecting approximately 12.5 million American youth,
population-level interventions are indicated to help support healthy
behaviors. The purpose of this review is to provide a summary of
population-level intervention strategies and specific intervention exam-
ples that illustrate ways to help prevent and control obesity in children
through improving nutrition and physical activity behaviors. Informa-
tion is summarized within the settings where children live, learn, and
play (early care and education, school, community, health care, home).
Intervention strategies are activities or changes intended to promote
healthful behaviors in children. They were identified from (a) systematic
reviews; (b) evidence- and expert consensus–based recommendations,
guidelines, or standards from nongovernmental or federal agencies;
and finally (c) peer-reviewed synthesis reviews. Intervention examples
illustrate how at least one of the strategies was used in a particular
setting. To identify interventions examples, we considered (a) peer-
reviewed literature as well as (b) additional sources with research-tested
and practice-based initiatives. Researchers and practitioners may use
this review as they set priorities and promote integration across settings
and to find research- and practice-tested intervention examples that can
be replicated in their communities for childhood obesity prevention.

Physical Fitness Involvement Among Young Adults and its Relation to other Act...Vinay Ghosh

https://academicwritingforstudents.com/visit-our-blog
Physical activity is one of the major traits among young adults and children. The level of
physical activities among children is found to be directly related to some common diseases like
obesity, cardiovascular diseases, diabetes, high blood pressure, and cancer. This paper consists of
a literature review of various research papers, which have been published in the context of
physical fitness. The various papers have been discussed to prove that physical fitness is directly
related to these diseases.
Peer involvement and skill-sharing was found to contribute to adolescents adopting and maintaining healthy lifestyles. A study evaluated a program called "Share Activities" where student leaders taught their peers about following the USDA's Dietary Guidelines through activities focused on eating breakfast, reducing sugary drinks, increasing fruit/vegetable intake, decreasing junk food, and increasing physical activity. Surveys found most peers were motivated to adopt healthy behaviors after participating and over half reported improving their diets, showing that peer influence can positively impact adolescents' health.
Obesity is quickly becoming one of the most common chronic.docxhopeaustin33688
Obesity is quickly becoming one of the most common chronic diseases among children. These rates have increased at an alarming rate and is a major public health problem because of related physical and psychological comorbidities, including type II diabetes, insulin resistance, metabolic syndrome, cardiovascular disease and mental health disorders. Dramatic increase in the number of overweight and obese children in recent years.
Studies indicate that children's lives may be shortened as a result of this alarming health problem. Estimates state that for any degree of overweight/obesity, younger adults (20-30 years of age) may have greater years of life lost due to obesity than older adults. Childhood obesity has been determined to be an independent risk factor for adult overweight/obesity.
To combat childhood obesity, there is a great need for public health interventions as well as education parents regarding childhood obesity and its consequences. Parents differ on causation of obesity, and differ in focus on nutrition and physical exercise. Many parents in the research do not see obesity as a barrier to physical activity. The parents need to recognize their child as overweight. Prevention is the most effective method for dealing with this growing health concern. The evidence reviewed, confirmed that family-centered interventions were associated with short-term reduction in obesity and improved medical parameters. The goal should be to involve community resources and provider referrals. Nurse Practitioners have a unique role in being the best facilitators to deliver health messages and are able to educate parents and increase awareness about the causes and consequences of childhood obesity.
Parents of young children need to interact with their child's primary healthcare provider for health advice and preventive health information during regularly scheduled physical examinations. It is up to the parents of these young children to combat intervention strategies such as:
a combination of nutritional and activity information, a cognitive-behavioral aspect to the intervention parent-directed activities
limiting sedentary child behaviors, provide positive approaches with children by parents and practitioners (e.g., emphasize positive rewards for healthy behaviors, encourage self-efficacy)
Future research is required to identify moderators and mediators to produce enduring changes in weight status of children.

It is meaningful to me since it is focused on contentment. Thus its moral obligation and importance is that it advocates for the satisfaction of the parties involved. The precedents of utilitarianism philosophy entail the following; that happiness of everyone counts uniformly, that actions are right if they result in pleasure otherwise wrong if they render unhappiness and that pleasure is the only thing that matters.
John Doe's involves a fiction scenario tailored at protecting the identity of witnesses in a case. Thus it is a slang name that informally represents the witnesses in a case to prevent them from manipulation by the defendant as their identity is rendered secretive (Smart, 2018). By application of the utilitarianism philosophy, a witness is considered to be happy (contented) if the identity is not revealed before the case for law during prosecution and hence we aspire to gain useful evidence. The morality of the theory revolves around its reliability as its only main obligation is to render witnesses pleasured. However, it might be termed immoral in situations where faithful information is required about every detail of the underlying case since no matter what; identity of the witnesses ought not to be revealed. Thus compromises its integrity.
Veil of ignorance constitutes the ethical reasoning whereby fair ruling is anticipated from a case by denying the parties involved any information that might bias them into suspecting who might benefit more from the ruling(Heen,2020). Thus in John Doe's case, when the identity of the witnesses is hidden, it is hard to identify possible relations of them with the plaintiff or defendant. This makes the judges seek justice independent of any information are sympathy to one of the parties at the expense of the other.’’
Apply to Jane Doe's case your personal moral philosophy as developed in week eight discussion and now. Use it to determine if what Jane Doe did was ethical or unethical per your own moral philosophy.
Consider if some of these examples are more grave instances of ethical transgressions than others. Explain.
Propose a course of social action and a solution by using the ethics of egoism, utilitarianism, the "veil of ignorance" method, deontological pr.

Service Quality and Patient-Centered
Care
L
eaders of the U.S. Depart -
ment of Health & Human
Services (2011) urge providers
to improve the overall quality of
health care by making it more
patient centered. Patient-centered
care (or person-centered care) refers
to the therapeutic relationship
between health care providers and
recipients of health care services,
with emphasis on meeting the
needs of individual patients. Al -
though the term has been used
widely in recent years, it remains a
poorly defined and conceptualized
phenomenon (Hobbs, 2009).
Patient-centered care is believed
to be holistic nursing care. It pro-
vides a mechanism for nurses to
engage patients as active partici-
pants in every aspect of their health
(Scott, 2010). Patient shadowing
and care flow mapping were used to
create a sense of empathy and
urgency among clinicians by clarify-
ing the patient and family experi-
ence. These two approaches, which
were meant to promote patient-cen-
tered care, can improve patient sat-
isfaction scores without increasing
costs (DiGioia, Lorenz, Greenhouse,
Bertoty, & Rocks, 2010). A better
under standing of attributes of
patient-centered care and areas for
improvement is needed in order to
develop nursing policies that in -
crease the use of this model in health
care settings.
The purpose of this discussion is
to clarify the concept of patient-cen-
tered care for consistency with the
common understanding about pa -
tient satisfaction and the quality of
care delivered from nurses to
patients. Attributes from a customer
service model, the Gap Model of
Service Quality, are used in a focus
on the perspective of the patient as
the driver and evaluator of service
quality. Relevant literature and the
Gap Model of Service Quality
(Parasuraman, Zeithaml, & Leonard,
1985) are reviewed. Four gaps in
patient-centered care are identified,
with discussion of nursing implica-
tions.
Background and Brief
Literature Review
Patient-Centered Care
The Institute of Medicine (IOM,
2001a) and Epstein and Street (2011)
identified patient-centeredness as
one of the areas for improvement in
health care quality. The IOM (2001b)
defined patient-centeredness as
…health care that establishes a
partnership among practition-
ers, patients, and their families
(when appropriate) to ensure
that decisions respect patients’
wants, needs, and preferences
and that patients have the edu-
cation and support they require
to make decisions and partici-
pate in their own care… (p. 7)
Charmel and Frampton (2008)
defined patient-centered care as
…a healthcare setting in which
patients are encouraged to be
actively involved in their care,
with a physical environment

Think of how many risks come into play when you decide to conduct a simple project, such as painting your living room. The following are some examples of risks:
What type of paint will you use (and can you afford high-quality paint)?
Who will move that brand new, big screen TV?
Who is going to paint?
Do you have the time, money, and resources?
Have you ever considered any of this, or do you simply cover up as much things as you can and start painting?
Risks exist regardless of whether people acknowledge it or not. Depending on the complexity of the project, the number and type of risk multiplies. Everyone has their own solution to each risk, but when working with a group within an organization, fragmentation such as this becomes counterproductive and a major risk in the end.
Scenario :
I have come with an Idea called ROSE which stands for Reserve on Site Easily, its a application that can be used on any phone. How it works is by lets say someone doesn't have a Wi-Fi connection or is not by Wi-Fi. What would happen is once by or near Wi-Fi their reservations will be saved and than will be sent to the hotel they would like to stay at, this will save a lot of time for not only them but the hotel as well. This will also save their spot until they have reached Wi-Fi, this will also be able to show what's available and what's not available when not on Wi-Fi.
Assignment:
Group Portion
As a group, you are to describe a project that all of you will participate in, and include the following:
Define the goal of the project
List the project's duration
Explain who are the stakeholders (those who participate)
*** Review benefits by the project implementation *** (My Portions)
Explain your need for resources
You need not go into in-depth details on the project.
Individual Portion
Each group member is to come up with 2 risks to this project. Each risk must include the following elements:
What technique(s) was used to identify the risk?
What type of risk is it, and does it have specific IT elements and considerations?
How was the risk assessed, and how does it rank with all of the risks identified by the group?
Is the risk qualitative or quantitative, and does it work with an EMV or Pareto analysis with all of the risks identified by the group?
What is the response to this risk, assuming it occurs during the project's lifecycle?
Provide at least 2 contingency plans for this risk (one primary and a second backup).
Group Portion
Combine the individual portion into a cohesive 6–8-page report that also includes the following:
A summary of the project (as discussed in the 1st group discussion)
How will the risks be monitored and controlled?
How will risks be communicated to all project participants?
*** What EVM comes from the risk management plan? *** (My Portion)
Are there any special tools utilized by the plan to manage all identified risks?

Coronavirus triggers cancellations, closures and contingency planning across the country
With daily reports of the deadly coronavirus spreading (Links to an external site.) into communities across the country, schools (Links to an external site.), companies, religious organizations and local governments are grappling with whether to shut down facilities and cancel events or to proceed, cautiously, as planned.
Increasingly, organizations are opting to cancel large gatherings, encourage remote work or take other steps (Links to an external site.) reflecting an abundance of caution about the virus, according to interviews with officials in several states. Others are making contingency plans about more-significant steps they might take in the case of a wider outbreak.
Washington Gov. Jay Inslee (Links to an external site.) (D) said people should prepare for disruptions in their daily lives as a result of the novel coronavirus, which has killed nine people in the state.
“Folks should begin to think about avoiding large events and assemblies,” Inslee said Monday. “We are not making a request formally right now for events to be canceled, but people should be prepared for that possibility.”
While the virus has been deadliest in Washington state, it has spread across the United States, with more than a dozen states reporting infections. There have been several instances of people contracting the virus while inside the country.
The response effort so far has been fragmented, with conflicting messages about the level of threat and the need for significant lifestyle changes.
“The general rule is, use common sense,” said Health and Human Services Secret.

A family based tailored counselling to increase
non-exercise physical activity in adults with a
sedentary job and physical activity in their young
children: design and methods of a year-long
randomized controlled trial
Taija Finni1*, Arja Sääkslahti2, Arto Laukkanen1, Arto Pesola1
and Sarianna Sipilä3
Abstract
Background: Epidemiological evidence suggests that decrease in
sedentary behaviour is beneficial for health. This
family based randomized controlled trial examines whether
face-to-face delivered counselling is effective in
reducing sedentary time and improving health in adults and
increasing moderate-to-vigorous activities in children.
Methods: The families are randomized after balancing
socioeconomic and environmental factors in the Jyväskylä
region, Finland. Inclusion criteria are: healthy men and women
with children 3-8 years old, and having an
occupation where they self-reportedly sit more than 50% of
their work time and children in all-day day-care in
kindergarten or in the first grade in primary school. Exclusion
criteria are: body mass index > 35 kg/m2, self-
reported chronic, long-term diseases, families with pregnant
mother at baseline and children with disorders
delaying motor development.
From both adults and children accelerometer data is collected
five times a year in one week periods. In addition,
2. fasting blood samples for whole blood count and serum
metabonomics, and diurnal heart rate variability for 3
days are assessed at baseline, 3, 6, 9, and 12 months follow-up
from adults. Quadriceps and hamstring muscle
activities providing detailed information on muscle inactivity
will be used to realize the maximum potential effect
of the intervention. Fundamental motor skills from children and
body composition from adults will be measured at
baseline, and at 6 and 12 months follow-up. Questionnaires of
family-influence-model, health and physical activity,
and dietary records are assessed. After the baseline
measurements the intervention group will receive tailored
counselling targeted to decrease sitting time by focusing on
commute and work time. The counselling regarding
leisure time is especially targeted to encourage toward family
physical activities such as visiting playgrounds and
non-built environments, where children can get diversified
stimulation for play and practice fundamental of motor
skills. The counselling will be reinforced during the first 6
months followed by a 6-month maintenance period.
Discussion: If shown to be effective, this unique family based
intervention to improve lifestyle behaviours in both
adults and children can provide translational model for
community use. This study can also provide knowledge
whether the lifestyle changes are transformed into relevant
biomarkers and self-reported health.

4. Therefore, not only adding physical activity but avoiding
inactivity has an important role in healthy lifestyle. Epi-
demiological studies have shown that sedentary time,
independent from exercise, predicts all-cause mortality
[7], obesity and type 2 diabetes [8,9], abnormal glucose
metabolism [10,11], the metabolic syndrome [12,13] and
cardiovascular disease [14]. In addition to the effects of
total sedentary time, the pattern in which it is accumu-
lated may be also important. Healy et al. [15] showed
that total number of breaks in sedentary time was asso-
ciated with lower waist circumference, triglycerides, and
2-h plasma glucose, independent of total sedentary time.
These authors suggested that breaking prolonged peri-
ods of sitting might be a valuable addition to the public
health recommendations. Although the evidence pro-
vides support to the importance of avoiding prolonged,
uninterrupted periods of sitting for cardiovascular health
in adults, further evidence from intervention trials is
required.
Promotion of sitting begins at schools at the latest and
increasing number of evidence show inactivity-related
symptoms also in adolescents and children [16]. Inter-
estingly, the amount of parent’s sedentary time, nor
their individual physical activity, seems to transfer to
their children [17,18]. On the other hand, parent’s and
siblings’ participation in physical activity with a child
and reinforcement for physical activity seems to be
important [19]. Thus, while our society supports sitting
and motorizing every action, promoting physically active
lifestyle as early as from childhood is crucial.
Based on Bandura’s [20] social cognitive theory, a
child learns by imitating and copying other people and
by making own reasons founded on these social situa-
tions. Own parents and siblings act as one of the most
5. powerful role models to a young child. Thus, the family
environment is in key position influencing child’s
physical activity habits taking shape in the childhood
[19,21-23].
The effective family interventions focused on increas-
ing physical activity in children have prompted parents
to set specific goals for changes in physical activity
behaviour and to self-monitor behaviour change pro-
gress and to identify barriers faced. It has also been
important that behaviour change techniques have
spanned the spectrum of behaviour change process [24].
Parents have been shown to be motivated to their role
as important models, if they receive knowledge why
physical activity (PA) is important to their children.
They also seem to profit from concrete ideas and model
how to promote physical activity with their children
[23].
For young children the parent’s encouragement
toward outdoor play seem to be essential [25] because
the amount of outdoor play correlates with overall phy-
sical activity [26,27]. Further, playing outdoors and
intensity level of moderate to vigorous physical activity
(MVPA) correlates with fundamental motor skills (FMS)
[28-30]. The more children are physically active the bet-
ter FMS they have and the more possibilities they have
to be physically active [31]. Good FMS during childhood
predict physical activity and physical fitness during ado-
lescence and later in adulthood [29,32,33]. On the other
hand, poor motor skills or clumsiness predicts low phy-
sical activity and poor physical fitness [34].
The purpose of this study is to find out the effects of
a tailored family based intervention on the activity level
6. of both parents and their children. In parents with a
sedentary job we investigate whether simple actions to
reduce time in sitting position are viable and whether
they have health-related benefits. Work-related inactivity
is one important aspect of the present study, since in
Finland 46% of women and 51% of men sit daily at least
6 h [35]. At the same time, we examine whether the
counselling delivered to parents on the importance of
children’s physical activity transfers to the increase in
children’s physical activity level and hereby facilitates
development of FMS.
The purpose of this article is to describe the design,
setting, recruitment process, methodology and interven-
tion of this randomized controlled trial.
Methods
Design
Parallel-group randomized controlled intervention trial
(RCT) design is used with one intervention group and
one control group of adults and their children. Adults in
the intervention group receive tailored counselling to
decrease time in sitting position and to increase non-
exercise daily activity. This counselling is also targeted
to encourage parents to increase their children’s time

spent outdoors and to increase children’s intensity of
activity toward MVPA level. Parents are also helped to
recognize the amount of children’s indoor activities,
7. especially sedentary behaviour like TV viewing and play-
ing video games.
An ethics approval for the project has been received
from the Ethics committee of Central Finland Health
Care District on March 25, 2011 (Dnro 6U/2011).
Before signing consent, an info meeting is held where
the subjects are informed about the procedures, risks
and benefits of the study, and where they can ask ques-
tions. Subjects are volunteers with right to withdraw
from the study at any time without consequences. Con-
sent for the children to participate in the study will be
signed by both legal guardians. The study is conducted
according to Declaration of Helsinki and good scientific
practice.
Subjects
Eligible participants are parents with work that primarily
includes sitting and their children of 3-8 years of age.
Inclusion criteria: healthy men and women with children
3-8 years old, and having an occupation where they self-
reportedly sit more than 50% of their work time. Chil-
dren in all-day day-care in kindergarten at least 10 days
per month or in the first grade in primary school. Exclu-
sion criteria: self-reported chronic, long-term musculos-
keletal disease or progressive neurological disease,
diagnosed cardiovascular or metabolic disease with regu-
lar medication, families with pregnant mother at base-
line and BMI > 35. Children with a developmental
disorder or other disorders delaying motor development
are excluded.
Sample size
In the entire project we aim to see the main effect of
the intervention as reduced inactivity time in adults.
Sample size was calculated by assuming that the inter-
8. vention could induce a decrease in the longest muscle
inactivity periods from 6.37 ± 3.42 min to 5.22 ± 2.59
min in persons sitting 50-100% of their work time. This
assumption was based on our data from previous project
[36] where a mean duration of five longest continuous
inactivity periods was measured from 84 people with
self reported sitting (%) during work. A sample size of
86 in both groups would have 80% power to detect this
18% difference at the level of a = 0.05. Estimating a
small cluster effect (1.133) [37] and drop outs a sample
size of 100 in both groups was reached. However, since
we also aim to show health effects of the intervention,
we used changes in plasma triglycerides as an example
of potential metabolic changes to estimate the power of
the design with 100 subjects. Olsen et al. [38] reported
triglycerides to change with 14 days reduction in
ambulatory activities from 617 ± 56 μmol/l to 647 ± 47
μmol/l. With the assumption that this effect is reversible
within a year with increased ambulatory activity, a sam-
ple size of 100 in both groups will have 98.4% power to
detect this change. In addition, while conventional
thinking holds that sample size is the primary adjustable
variable for increasing statistical power, effect sizes
depend on phenotypic definition and will likely increase
the closer one connects to the underlying biochemistry
[39]. Since the metabonomic analysis provides more
detailed phenotype characterization this translates to
even greater statistical power.
Setting and randomization
The recruitment is performed in the city of Jyväskylä,
Finland, by delivering advertisements to parents via kin-
dergartens and primary schools which have been pre-
randomized to control and intervention groups after
balancing different environmental and socioeconomic
9. regions within the city. Jyväskylä with 130,000 residents
and surface area of 1171 km2 has relatively small city
centre and suburbs are characterized with proximity of
lakes and forests. In the city opportunities for active
commute using built-in bike paths and sidewalks are
numerous although winter with snow creates challenges
for a year-around commute. Also many of the kinder-
gartens and primary schools have the possibility to uti-
lize the natural environments in their daily program.
The compulsory education begins in August at the same
year children have their seventh birthday. Before the first
school year, 96% of Finnish children participate to a year-
long voluntary preschool [40]. The average enrolment rate
of children aged 3-5 years in childcare and early education
services is 74% in Finland which is slightly lower than
average of 77% in OECD-countries [41]. Kindergarten tea-
chers have the pedagogical responsibility of children’s
early education and their proficiency requirement is 3-5-
years of university or polytechnic education.
The recruitment started in April 2011 with five kin-
dergartens that resulted in about 16% response rate.
Based on this initial result we estimated that randomiza-
tion of 32 kindergartens and schools would be required
to reach required sample size. In the randomization the
areas within the city centre and in different types of
suburbs were balanced. Regarding socioeconomic
regions, information from city registry was used to bal-
ance the areas. Thus, in each type of environment and
socioeconomic region there were to be two or more kin-
dergartens and/or primary schools that were then ran-
domized into control and intervention groups.
Intervention
Tailored counselling by research personnel (TF, AL, AP)
10. is targeted to decrease time in sitting position and
Finni et al. BMC Public Health 2011, 11:944
http://www.biomedcentral.com/1471-2458/11/944
Page 3 of 8
increase non-exercise activity during workdays (com-
mute and work time) and in leisure time (evenings and
weekends) in adults. A common 30-min lecture is given
to maximum of six participants accompanied with face-
to-face discussions. The lecture contains research-based
justifications for physical activity recommendations,
effects of physical activity and, specifically for adults,
information why reduction in sitting time can be
beneficial.
In the discussions the subjects will be first asked to
describe their current way of commute to work and to
think of feasible ways of increasing active modes of
commute. Then goals set by the subject regarding the
mode and frequency of the change (e.g. Instead of tak-
ing the bus I will bicycle to work i) sometimes, ii) once
a week, iii) several days a week, iv) every day) will be
marked down to a form.
Second, the work time will be discussed and the sub-
jects are asked to identify items that can be modulated,
e.g. standing in coffee breaks, walking about while talk-
ing to phone, breaking long periods of sitting, taking a
walk before lunch etc. Third, considering leisure time
(both weekdays and weekends) is especially focused to
encourage families to spend time together in nature and
non-built environments, playgrounds and parks where
11. children can get diversified stimulation for play. In dis-
cussions the parents are also encouraged, if needed, to
reinforce children to play outdoors with peers, to
acquire motivational equipment for play, to maintain
summertime physical activity level and to utilize the
material given. Moreover, leisure time habits will be
asked and changes in habits such as walking to grocery
shop instead of driving by car or walking stairs instead
of taking the lift are discussed.
The items that the subjects themselves suggest to
modify will be written down and an agreement docu-
ment will be signed by the subject and researcher to
confirm the intended changes in behaviour.
During counselling, material for break exercises during
work time, children’s indoor and outdoor activities and
local places for hiking are delivered. Documents
“License to Move” and a fair copy of the agreement are
given. The subjects are also informed about project
web-page [42] containing motivational material for
intervention group which will be regularly updated.
The counselling is reinforced by a phone call after 1
and 5 months during which the compliance is asked
and modifications to the agreement can be made. Dur-
ing the phone discussions execution (both compliance
and barriers) of each of the goals are asked and modi-
fied when required. In addition, motivational e-mails
with information on health promotion by life-style phy-
sical activity for adults and illustrative tips to increase
physical activity and play developing FMS in children
are sent monthly. This reinforcement period lasts for 6
months. At Midline the subjects in the intervention
group will be given individual feedback of their daily
inactivity and activity times (from Baseline muscle activ-
12. ity measurements). Feedback of children’s motor skills
with motivational tips will also be given at Midline.
After the Midline there will be no researcher contact
with the subjects except for the 9 month measurements.
The control group will not receive the counselling
intervention but will undergo the measurements simi-
larly as the intervention group. After 12 month-mea-
surements the control group will be invited to a
feedback and counselling session where they have the
possibility to receive the same information as the inter-
vention group.

morning are
assessed at these time points as well as fasting blood samples.
At baseline, midline and endline questionnaires, body
composition, daily activity
tasks are assessed. At these 3 time points PA measurements
include 1-day thigh muscle activity measurements.

initiate 1 week physical activity recordings during normal
14. daily life. Counselling takes place few weeks after the
baseline, and the maximum effect of counselling on phy-
sical activity will be tested about 1 week after the coun-
selling (0 months). At this time data will also be collected
from control group who is told that this assessment
relates to reliability and they are to live a normal life
similarly as in all the other measurements. The measure-
ments at 3 and 9 months include only fasting blood sam-
ple, heart rate and accelerometer measurements.
Baseline, Midline and Endline measurements initiate
physical activity monitoring during normal daily life
(Figure 2). The subjects will wear shorts measuring
muscle activity for 1 day, heart rate device for 3 days
and 2 nights and accelerometer for 7 days. During the
days of physical activity data collection the subjects fill
in physical activity diaries with information on sleep
quality, alcohol usage and particularly stressful
situations.
Outcome measures from adults
Short term main outcome is the PA behaviour which will
be assessed with electromyography (EMG) and acceler-
ometer. PA measured using EMG during 1 day at base-
line will be compared to the daily measurements done
after counselling. During this day, that is similar work-
day as in the baseline, the subjects are instructed to
carefully execute the agreed changes in their PA beha-
viour allowing examination of maximal effect of the
counselling. In the control group, this measurement will
serve repeatability assessment. Commute time, work
time and leisure time will be analyzed separately.
EMG will be measured using shorts with embedded
textile electrodes (Myontec Ltd., Kuopio, Finland) mea-
suring activity from left and right quadriceps and ham-
string muscles (Figure 3). The measurement system has
15. been tested for validity, repeatability and feasibility in
our laboratory [43]. The data is collected to a 52 g
module in the waist in raw form with sampling fre-
quency of 1000 Hz. The raw EMG signal is rectified and
averaged over 100 ms non-overlapping intervals before
storing the data into the module. The daily EMG level
will be normalized to that during isometric maximum
voluntary contraction. Inactivity threshold is individually
determined as 0.9% of the standing EMG level. Several
activity and inactivity parameters will be analyzed using
custom made Matlab program including burst analysis
[44].
Acceleration Triaxial acceleration will be collected dur-
ing all the measurements (Alive heart monitor, Alive
technologies Ltd., Australia). We will analyze the com-
monly used activity counts but also use signal half
power and histograms to describe changes in PA beha-
viour. Alive monitor can simultaneously collect also
electrocardiogram from which the heart rate variability
and related stress indices are calculated using Hyvin-
vointianalyysi-software (Firstbeattechnologies Ltd.,
Finland).
Long term main outcomes are health-related indices
and maintenance of the behavioural change. Changes in
physical activity behaviour will be assessed using EMG,
accelerometer and questionnaires. The health indices to
be collected 5 times a year are fasting blood samples
and diurnal heart rate (Figure 1). Blood pressure and
body composition with dual energy x-ray absorptiometry
(DXA, LUNAR Prodigy, GE Healthcare) will be mea-
sured at Baseline, Midline and Endline in fasting
condition.
Venous blood samples for whole blood count, blood
16. lipids and glucose will be taken in standardized fasting
conditions in the mornings 7-9 am. Samples will be ana-
lyzed using standard methods in clinical use. Serum will
be stored at-80°C for later analysis of the entire serum
metabolome via NMR spectroscopy. This methodology
provides information on ~150 primary metabolic

measures and ~100 derived variables with clear bio-
chemical interpretation and significance. The directly
measured metabolites include lipoprotein subclass distri-
bution with 14 subclasses quantified including particle
concentrations and individual subclass lipids, low-mole-
cular-weight metabolites such as amino acids, ketone
bodies, and creatinine, and detailed molecular informa-
tion on serum lipid extracts including free and esterified
cholesterol, sphingomyelin, degree of saturation and ω-3
fatty acids. Derived variables include selected ratios of
metabolites implicated in lipolysis, proteolysis, ketogen-
esis and glycolysis as well as reagents and products of
enzymatic reactions and measures obtained with the
extended-Friedewald formula, eg. apolipoprotein A-I
and B [45]. Further details of the NMR spectroscopy,
quantification data analyses, as well as the full metabo-
17. lite identifications can be found from [46,47].
Heart rate will be measured with the same device as
acceleration. The subjects wear the monitors for 3 days
and 2 nights. In the morning the subjects will perform
an orthostatic test. Previously, heart rate variability from
this test has been shown to correlate with self-reported
stress [48]. Both time domain and frequency domain
analysis of heart rate variability will be performed,
where high frequency band has special meaning in
determining cardiovascular health [49].
Questionnaires Background information of medica-
tion, chronic and acute diseases will be assessed in the
screening process. Dietary records for 3 weekdays and
1 weekend day will be kept at Baseline and Endline
and 1 day diaries at 3, 6 and 9 months to evaluate
whether similar diet has been maintained during the
year as assumed. The subjects will also fill in the fol-
lowing questionnaires: Socio-economic background
(Baseline), 12-month physical activity (Baseline, End-
line, modified from [50], quality of life (RAND-36,
Baseline, Endline), Work Ability Index (Baseline, End-
line) and Occupational Stress Questionnaire (Baseline,
Midline, Endline) (Finnish Institute of Occupational
Health). Physical fitness will be assessed with non-exer-
cise questionnaire (Baseline, Endline) and additional
details of physical activity intensity and frequency will
be asked at all time points. Family-Influence Model
questionnaire [19] will be assessed in Baseline, Midline
and Endline.
Protocol for children
At Baseline, 3, 6, 9 and 12 months, children will be
measured for physical activity level during waking hours
for 6 days. During the days of physical activity measure-
18. ments the parents will mark down to the children’s
diary the times the accelerometer were put on and
taken off. In addition, parents are asked to subjectively
estimate the amount of children’s MVPA time after day-
care or school. At Baseline, Midline and Endline chil-
dren will also be measured for FMS.
Outcome measures from children
Physical activity will be measured using triaxial accel-
erometer (X6-1A USB Accelerometer, Gulf Coast Data
Concepts, USA) which is placed on children’s waist
with firmly fitted elastic band. The time at day-care or
school will be analyzed separately from leisure time.
Extracted variables will include commonly used activity
counts based on thresholds [51], histograms and half
power of the signal. FMS will be tested using Körper-
koordinations Test fur Kinder (KTK) [52] for balance
and motor coordination and using APM object control
test [53]. APM is a widely used motor skill test for
children in Finland. FMS tests are conducted as part of
daily activities in kindergartens, schools and, in some
cases, in the laboratory of Department of Biology of
Physical Activity.
Statistical analysis
The maximal effect of counselling will be tested using
mixed model ANOVA comparing the control and inter-
vention groups at baseline and at 0 months. Repeated
measures ANOVA will be used to determine effects of
intervention with an intention-to-treat principle. Mixed
models are used in case of missing data points and to
examine the clustering effect as well as to examine the
relationships between physical activity and health-related
indices. Self-organizing maps (SOM) will be applied for
multi-metabolic understanding of metabolic interrela-
tionships and pathways [54,55].

Discussion
This study is unique in implementing intervention to
both parents and their children at the same time. The
intervention focusing on reducing inactivity rather than
increasing physical activity is a rather new concept and
the actual execution by the adults is likely to determine
the significance of this study. For the intervention group
we have carefully designed a motivating environment
with face-to-face discussions where the goals will be set
by the subjects themselves and the commitment is for-
malized by signing an agreement. This type of interven-
tion has been shown to be very effective [56].
To reliably extract the possible changes in physical
activity the present study utilizes both conventional
(such as activity counts from accelerometer) and novel
methods (histograms and signal half power from accel-
erometer and EMG) for more accurate determination of
physical activity intensity and durations. Further, the
measurements are done long enough periods 5 times
during the year to assess the altered behaviour. Whether
the altered behaviour in adults is reflected to health, it
is postulated that the metabonomics analysis is sensitive
enough to detect even subtle changes that would not be
20. visible in conventional clinical markers.
There are challenges in this trial. Firstly, the compli-
ance cannot be foreseen. The subject group is at very
busy stage of life making careers with small children
and a year-long commitment may result in considerable
attrition rates. Further, seasonal variations in Finland
with warm summer and cold winter with snow may
show a greater effect on physical activity and health
indexes than the low threshold intervention. We have
considered this effect by performing the baseline mea-
surements sequentially in spring and fall seasons.
Overall, this study has the potential to provide novel
and timely information on the cause-effect relationships
of low threshold physical activity intervention. However,
the effectiveness of the intervention can only be assessed
after the end of the study.

Attention-deficit/Hyperactivity Disorder (ADHD) is
characterized by a pervasive pattern of developmen-
tally inappropriate inattentive, impulsive and hyperactive
behaviors that typically begin during the
preschool years and often persist into adulthood. The most
effective and widely used treatments for
ADHD are medication and behavior modification. These
empirically-supported interventions are gen-
erally successful in reducing ADHD symptoms, but treatment
effects are rarely maintained beyond the
active intervention. Because ADHD is now generally thought of
as a chronic disorder that is often present
well into adolescence and early adulthood, the need for
continued treatment throughout the lifetime is

both costly and problematic for a number of logistical reasons.
Therefore, it would be highly beneficial
if treatments would have lasting effects that remain after the
intervention is terminated. This review
examines the burgeoning literature on the underlying neural
determinants of ADHD along with research
demonstrating powerful influences of environmental factors on

. Introduction
Attention-deficit/Hyperactivity Disorder (ADHD) is a chronic,
ighly prevalent neurodevelopmental disorder which affects as
any as 9% of school-age children (Pastor and Reuben, 2008).
ADHD
ypically emerges during the preschool years, persists through
dolescence and into adulthood for many afflicted individuals,
nd causes significant functional disability throughout the
lifespan
American Psychiatric Association Task Force on DSM-IV,
2000).
everal effective empirically-validated psychopharmacologic and
ehavioral interventions for ADHD are currently available. These
nterventions have been shown to ameliorate the core symptoms
f ADHD and to improve academic performance across a wide
array
f school-related measures. However, such gains are rarely main-
ained after the termination of treatment (Chronis et al., 2003,
004; Jensen et al., 2007), and relatively few individuals with
ADHD
eceive effective treatment throughout the full course of their
dis-
43. rder (Corkum et al., 1999; Jensen et al., 2007; MTA
Cooperative
roup, 1999, 2004; Perwien et al., 2004; Sanchez et al., 2005;
Weiss
t al., 2006; Molina et al., 2009). The need for continued
treatment
hroughout the lifetime is both costly and problematic for a num-
er of logistical reasons. Therefore, it would be highly beneficial
if
treatment could be employed that would have lasting effects
that
emain after the active intervention is terminated.
Recent research has begun to elucidate the underlying neu-
al (Casey et al., 1997; Castellanos, 2001; Makris et al., 2007;
chulz et al., 2004, 2005a; Seidman et al., 2005; Shaw et al.,
2006,
007a,b) and neurocognitive (Sergeant et al., 1999; van Mourik
et
l., 2005; Willcutt et al., 2005) determinants of ADHD.
Additionally,
distinct scientific literature, largely consisting of research with
nimals, indicates that an array of neurodevelopmental processes
acilitate efficient neurotransmission and are highly responsive
to
nvironmental influences. The bringing together of these
scientific
iteratures may provide valuable insights for the development of
ore enduring treatments for ADHD.
. Overview of evidence-based treatments for ADHD
Pharmacological interventions, most prominently stimulant
44. edication, and behavioral interventions in the forms of par-
nt training and contingency management in the classroom, are
onsidered the best-supported treatments for ADHD. These inter-
entions result in significant benefits for children with ADHD in
ultiple domains of functioning (Conners, 2002; Greenhill et al.,
999; Pelham et al., 1998; Pelham and Fabiano, 2008; Spencer
t al., 1996). For example, studies of behavioral parent train-
ng (BPT) for ADHD have demonstrated improvements in ADHD
ymptoms (Anastopoulos et al., 1993; Sonuga-Barke et al., 2001;
unningham et al., 1995), as well as co-occurring oppositional
roblems and impairment in children (Erhardt and Baker, 1990;
isterman et al., 1989, 1992). BPT also improves parental
function-
ng (e.g., decreased stress, enhanced competence) (Anastopoulos
t al., 1993; Pisterman et al., 1992; Sonuga-Barke et al., 2001).
oreover, behavior contingency management in the classroom
ields improvements in teacher reports of children’s functioning,
bserved behavior of children with ADHD in the classroom set-
ing, as well as better academic productivity (Abramowitz et al.,
987; Fabiano et al., 2007; Pelham et al., 1998; Hoffman and
DuPaul,
000). While data indicate that behavioral treatments are not, on
he group level, as effective as carefully-monitored stimulant
medi-
ation, the large Multimodal Treatment Study of ADHD (MTA
Study)
ound that their pure behavioral treatment group improved to a
imilar degree as their community treated control group, the
major-
ty of whom received medication treatment from their provider
utside of the study (MTA Cooperative Group, 1999).
45. iobehavioral Reviews 35 (2011) 621–634
Stimulant medication has been shown to improve functioning
in children with ADHD, with studies demonstrating
improvements
in core symptoms of ADHD, compliance, aggression, and
academic
productivity (Conners, 2002; Greenhill et al., 1999; Spencer et
al.,
1996). Effect-size calculations from both behavioral
interventions
and stimulant medication studies demonstrate that these inter-
ventions result in substantial improvements across domains of
functioning (Conners, 2002; Pelham and Fabiano, 2008).
Collec-
tively, compelling evidence indicates that behavioral
interventions
and stimulant medication improve the functioning of children
with
ADHD and, in some cases, have additional benefits for their
families.
However, noted below, are several limitations to these
treatments
which necessitate further investigation into alternative interven-
tions for children with ADHD.
2.1. Key limitations of current evidence-based interventions for
ADHD
Although clearly efficacious, there are limitations to current
evidence-based interventions. Stimulant medication is an easy
intervention to implement, but many parents prefer not to use
medication as a treatment for their child with ADHD (Pisecco et
al., 2001; Power et al., 1995). Moreover, a substantial number
of
children experience notable side effects with stimulant medica-
46. tion (MTA Cooperative Group, 2004; Swanson et al., 2006,
2007a;
Wigal et al., 2006) that may prohibit continued use. In addition,
recent concerns have been raised by the American Heart Associ-
ation (American Heart Association, 2008) suggesting
problematic
interactive effects of stimulant medication with underlying car-
diac conditions that may further limit the acceptability of
stimulant
medication for children with ADHD, or at least make it less
palatable
to parents. Behavioral interventions, in contrast, are more
palatable
but much more difficult to implement, generally quite costly,
and
may be less effective than stimulant medications (MTA
Cooperative
Group, 1999).
In addition, there are several limitations that both stimulant
medication and behavioral interventions share in common. First,
although both treatments are efficacious, the behavior of a
signif-
icant number of children with ADHD is not normalized by the
use
of these interventions (Hoza et al., 2005; Swanson et al., 2001).
Swanson et al. (2001) found that 32–64% of children continued
to
exhibit clinically significant levels of ADHD despite intensive
stim-
ulant medication and behavioral treatment regimens. Moreover,
Hoza et al. (2005) found that despite intensive treatment over
14
months, children continued to have difficulties in peer relation-
ships. Therefore, although children with ADHD may do
significantly
47. better with stimulant medication and/or behavioral interventions
relative to baseline, they still appear deviant relative to their
peers
in key areas of functioning.
Furthermore, treatment effects rarely persist past the point of
active dosing/implementation (Chronis et al., 2003, 2004). This
suggests that implementation of behavioral interventions and
stimulant medication temporarily suppresses behavioral
difficul-
ties and that these difficulties resurface when treatment is no
longer active. As such, there are no apparent changes in the
under-
lying deficits that produce the behavioral manifestations of
ADHD.
In addition, although ADHD is considered a chronic condi-
tion that impacts functioning across multiple settings, which
would thus require long-term treatment that impacts each
affected
setting, long-term adherence to both stimulant medication and
behavioral interventions is often poor. For instance, there is
considerable noncompliance with stimulant medication (MTA
Cooperative Group, 2004; Corkum et al., 1999; Jensen et al.,
2007;
Perwien et al., 2004; Sanchez et al., 2005; Weiss et al., 2006).
More
than half of children prescribed stimulant medication stop
receiv-
ing treatment within a school year (Sanchez et al., 2005), and
most
50. l., 2006). For behavioral interventions to be implemented over
the
ong-term, willingness among key adults (teachers and parents)
to
mplement highly intensive interventions over long periods of
time,
ith high levels of fidelity, is necessary but extremely
challenging
Chronis et al., 2001; Witt, 1986).
Lastly, the collective evidence suggests that stimulant medi-
ation use has few, if any, long-term benefits for children with
DHD (Charles and Schain, 1981; Loe and Feldman, 2007;
Molina
t al., 2007; Paternite et al., 1999; Satterfield et al., 1982;
Swanson
t al., 2007b; Weiss and Hechtman, 1993; Molina et al., 2009).
his finding also applies to behavioral interventions (Molina et
l., 2007; Pelham and Fabiano, 2008). Thus, although acute ben-
fits of stimulant medication and behavioral interventions are
ell-documented in the literature, the lack of normalization of
unctioning for many children following treatment, lack of
gener-
lization of treatment effects, difficulties in long-term
adherence,
nd lack of clear improvement in long-term functioning
following
he use of these interventions are discouraging.
Given these findings, an alternative approach to ameliorating
he difficulties of children with ADHD is indicted. The extensive
lit-
rature indicating neurobiological deficits in ADHD, and the
51. strong
ody of evidence regarding neural rehabilitation, suggests that
esearch examining the impact of pharmacologic as well as envi-
onmental manipulations on neural growth, and lasting cognitive
unction, could provide a potentially fruitful avenue for novel
treat-
ent approaches for this highly impairing and oftentimes life-
long
isorder.
. Neural substrates of ADHD
.1. Neuroimaging evidence
Neuroimaging studies suggest an important role for frontostri-
tal circuits along with a wide array of other cortical and
subcortical
rain regions in the pathophysiology of ADHD. Numerous struc-
ural MRI studies have reported smaller regions in the prefrontal
ortex (PFC) of youth with ADHD (Castellanos et al., 1996,
2002;
urston et al., 2004; Filipek et al., 1997; Hynd et al., 1990; Kates
t al., 2002; Mostofsky et al., 2002; Sowell et al., 2003). Simi-
arly, studies have found reduced caudate nucleus size (Filipek
et
l., 1997; Hynd et al., 1993), reduced volume in the globus pal-
idus (Castellanos et al., 1996); and reduced callosal area in
ADHD
Baumgardner et al., 1996; Giedd et al., 1994; Hynd et al., 1991;
Hill
t al., 2003; Lyoo et al., 1996; Semrud-Clikeman et al., 1994).
Structural anomalies have also been reported in several brain
egions outside of the frontal lobes and striatum. Studies have
oted reduced volume in several parts of the cerebellum in
52. ADHD
Castellanos et al., 2002, 1996; Durston et al., 2004; Posner and
etersen, 1990) as well as posterior cortical anomalies (Durston
et
l., 2004; Filipek et al., 1997; Sowell et al., 2003). Additionally,
sev-
ral (Berquin et al., 1998; Castellanos et al., 1996, 2002;
Castellanos,
001; Hill et al., 2003), but not all (Durston et al., 2004; Filipek
et
l., 1997; Hynd et al., 1990; Mostofsky et al., 2002), studies
report
educed whole brain size in children with ADHD. A key review
of
he structural MRI literature (Seidman et al., 2005) found
support
or the notion that ADHD is associated with frontostriatal abnor-
alities. However, an increasing number of studies,
demonstrating
idespread neural abnormalities affecting other cortical regions
nd the cerebellum, were highlighted.
Recently, studies have begun to use MRI to examine differ-
nces in cortical thickness between individuals with and without
DHD. In a series of developmentally-sensitive longitudinal
stud-
iobehavioral Reviews 35 (2011) 621–634 623
ies Shaw et al. (2006, 2007a,b) reported that children with
ADHD
followed a similar sequential pattern of cortical development,
yet
53. were delayed by as much as 2–3 years, depending upon the
specific
cortical region (Shaw et al., 2007a). These findings were inter-
preted as suggesting developmental delays rather than
permanent
anomalies in ADHD. Additional research from this group (Shaw
et
al., 2006) found links between cortical thickness and clinical
out-
come such that ADHD children with worse outcome had “fixed”
thinning of the left medial PFC and those with better outcomes
had right parietal normalization, which was suggested to
represent
compensatory cortical change. Similarly, McAlonan et al.
(2009)
reported an association between the magnitude of age-related
growth in the anterior cingulate, striatum and medial temporal
cortex, and improvements in neurocognitive measures of
response
inhibition in school-age children with ADHD. Further, better
clin-
ical outcome was linked to the presence of the DRD4-7-repeat
allele (Shaw et al., 2007b), which was associated with thinner
right orbitofrontal/inferior prefrontal and posterior parietal cor-
tices. This thinning was most apparent in childhood and largely
resolved in adolescence. Yet, these executive function networks
which include the dorsolateral PFC, anterior cingulate cortex
and
inferior parietal lobe remain thinner in adults with ADHD
(Makris
et al., 2007). A recent review focusing on trajectories of brain
devel-
opment (Shaw et al., 2010) suggests that remission in ADHD
with
age may be linked to a normalization of initial delays or deficits
in
54. brain networks, whereas ADHD persistence into adolescence
may
be associated with a lack of normalization and perhaps a more
deviant trajectory of brain growth.
Consistent with the structural MRI data, functional MRI (fMRI)
studies provide compelling data indicating functional brain dif-
ferences between individuals with ADHD and controls. These
functional studies have linked neural anomalies to deficiencies
in
a wide array of neurocognitive processes including inhibitory
con-
trol (Casey et al., 1997; Durston et al., 2003; Schulz et al.,
2004,
2005a; Tamm et al., 2004; Vaidya et al., 1998), conflict resolu-
tion (Bush et al., 1999; Tamm et al., 2004), motor control
(Rubia
et al., 1999), timing (Durston et al., 2007), attention (Cao et al.,
2008; Sonuga-Barke and Castellanos, 2007; Uddin et al., 2008)
and
working memory (Valera et al., 2005). Although findings have
not
always been consistent, many studies have reported greater and
more diffuse PFC and basal ganglia responses to increased
cognitive
demands in participants with ADHD. These findings are
reminis-
cent of the immature brain function associated with
susceptibility
to interference in young children (Casey et al., 2002).
Recently, there has been an emerging shift in focus among neu-
roimaging studies from the examination of specific brain
regions
to an examination of networks or how specific regions are con-
nected or interact (for review, see Konrad and Eickhoff, 2010).
55. This
research, which is in its infancy and still has many methodolog-
ical issues to tackle, has focused largely, on two proposed
neural
systems. The Default Mode Network (DFN), comprised of the
pre-
cuneus, posterior cingulate cortex, the medial prefrontal cortex
and portions of the parietal cortex (Schilbach et al., 2008), has
been shown to be most active during rest, and to deactivate dur-
ing active task engagement (Raichle et al., 2001). In contrast, a
second network, which includes the dorsolateral prefrontal cor-
tex, the intraparietal sulcus, and the supplementary motor area
is more quiescent during rest and becomes activated during
peri-
ods of task engagement. This latter system seems more linked to
increased alertness and response preparation than to any
specific
cognitive process (Konrad and Eickhoff, 2010). These two
neural
systems have been described as being ‘anti-correlated’ such that
when the task positive fronto-parietal system turns-on in
response
to task demands, the DFN becomes less active, and when at rest
the DFN is most active, and activity in the fronto-parietal
system
diminishes (Fox et al., 2005; Sonuga-Barke and Castellanos,
2007).

When comparing ADHD participants to controls, some data sug-
est, reduced functional activity and connectivity within the DFN
uring rest (Castellanos et al., 2008; Uddin et al., 2008), but oth-
rs report an overactive DFN during quiescence (Tian et al.,
2006,
008). Sonuga-Barke and Castellanos (2007) have hypothesized
hat, among those with ADHD, the DFN does not adequately
deac-
58. ivate during task engagement, which in turn interferes with the
eural circuits that underlie the ability to efficiently engage in
ctive tasks. According to this hypothesis, the interference
results
n frequent errors and lapses in attention, as evidenced by the
requently reported increased reaction time variability associated
ith ADHD (Castellanos and Tannock, 2002; Kuntsi et al., 2001;
ussell et al., 2006). Notably, psychostimulant treatment has
been
ound to improve DFN suppression during active task
engagement
n youth with ADHD (Peterson et al., 2009), as well as to
decrease
eaction time variability (Spencer et al., 2009).
Finally, recent research has also examined connectivity during
ctive task engagement. Two studies (Rubia et al., 2010; Vloet et
l., 2010) have reported decreased functional connectivity during
ctive task performance in children with ADHD, which may in
part
e normalized by treatment with stimulant medication (Rubia et
l., 2009). However, in adults with ADHD a more complicated
pat-
ern of regional increases and decreases in functional
connectivity
as been reported (Wolf et al., 2009).
Thus, when taken together, neuroimaging studies provide com-
elling evidence for neurodevelopmental differences between
ndividuals with and without ADHD that span a wide array of
brain
egions and neural circuits.
.2. Neuropsychological findings
59. Consistent with the neuroimaging data, neuropsychological
ata provide clear evidence that children with ADHD have
impair-
ents in a wide array of neurocognitive domains. Much of the
iterature has focused on executive functions (EFs) which are
ediated by circuits involving the PFC. Studies most consistently
nd deficits in inhibitory control (Barkley, 1997; Casey et al.,
997; Durston et al., 2003), regulation of attention (Pennington
t al., 1993; Swanson et al., 1991; Halperin et al., 1993; Johnson
t al., 2008), working memory (Castellanos and Tannock, 2002;
artinussen et al., 2005), planning (Pennington et al., 1993;
arkley, 1997), and shifting sets (Seidman et al., 1995; Reader et
al.,
994; Hall et al., 1997). Willcutt et al.’s (2005) meta-analysis of
83
tudies (total N = 6703), which focused on 13 EF tasks, clearly
indi-
ated that groups of children with ADHD perform more poorly
than
ontrols on many EF measures, with effect sizes generally in the
edium range (.46–.69). However, because of the relatively mod-
st effect sizes, it was concluded that EF weaknesses are “neither
ecessary nor sufficient to cause all cases of ADHD.”
Nonetheless,
F deficits likely contribute to the functional impairments that
are
resent in many children with ADHD.
Despite the common conceptualization of ADHD as a disorder
of
Fs (Barkley, 1997), children with ADHD also differ from
60. controls
n a broad range of non-EF functions such as motor coordination
Blondis, 1999; Carte et al., 1996; Kadesjo et al., 2001;
Sheppard
t al., 2000; Steger et al., 2001), perception (Garcia-Sanchez et
al.,
997; Mangeot et al., 2001), language (Beitchman et al., 1987,
1996;
arte et al., 1996; Humphries et al., 1994; Purvis and Tannock,
1997;
irosh and Cohen, 1998), visuomotor integration (Raggio, 1999),
nd learning and memory (Felton et al., 1987). Meta-analyses
Frazier et al., 2004; van Mourik et al., 2005; Willcutt et al.,
2005)
ndicate an array of executive and non-executive function
deficits
n children with ADHD. Furthermore, increased variability in
reac-
ion time (RT) is among the most consistently reported deficits
n children with ADHD (Castellanos and Tannock, 2002; Russell
t al., 2006; Spencer et al., 2009). Additional presumably “non-
iobehavioral Reviews 35 (2011) 621–634
executive” parameters have been shown to differentiate ADHD
from non-ADHD children, including signal detectability (d′) and
response bias (ln ˇ) variables from continuous performance tests
(CPTs; Losier et al., 1996). Kuntsi et al. (2001) reported that
RT
variability discriminated ADHD children from controls better
than
measures of inhibition and working memory, and Epstein and
col-
leagues (Epstein et al., 2003) reported variability in d′, ln ˇ, and
RT
61. to be strongly associated across multiple ADHD symptom
domains.
A recent study (Rommelse et al., 2007) reported that after
control-
ling for “lower order” cognitive processes, there was little
evidence
for primary EF deficits in children with ADHD. As such, some
have
hypothesized that the EF deficits frequently observed in
children
with ADHD may be due to deficiencies in largely subcortical,
reg-
ulatory systems, rather than cortical EF circuitry per se
(Douglas,
1999; Halperin and Schulz, 2006; Rommelse et al., 2007;
Sergeant
et al., 1999; Sonuga-Barke and Castellanos, 2007).
In addition to more broadly assessing neurocognitive deficits in
individuals with ADHD, several studies have focused more
specif-
ically on the three distributed neural networks hypothesized to
underlie attention (Posner and Petersen, 1990). One meta-
analysis
of 14 studies found little or no evidence for any visuospatial
atten-
tion deficits in ADHD, including those functions typically
attributed
to the anterior or executive attention system (Huang-Pollock
and
Nigg, 2003). However, more recently, Johnson et al. (2008)
reported
evidence for impaired alerting and conflict resolution in youth
with
ADHD as measured using the Attention Network Test (ANT;
Fan et
62. al., 2002). As posited by Posner and colleagues, the alerting
network
is driven largely by noradrenergic input from the locus
coeruleus to
the frontal and parietal lobes, whereas conflict resolution is
more
closely linked to a dopaminergic system involving the basal
ganglia,
anterior cingulate and the dorsolateral prefrontal cortex (Posner
and Petersen, 1990; Posner et al., 2006).
From this review of the neuropsychological and neuroimaging
studies, we can see that the findings do not support simple mod-
els that posit that ADHD is due to dysfunction of a few isolated
brain regions, including the PFC. Rather, individuals with
ADHD dif-
fer from controls on measures derived from multiple brain
regions
and across a wide array of neurocognitive domains. Further,
stud-
ies examining cortical thickness provide compelling evidence
that
careful examination of developmental trajectories may be key to
uncovering the neural substrates of ADHD, and that clinical
out-
comes might be linked to cortical development and
compensatory
mechanisms that develop throughout childhood.
4. Neurodevelopmental perspectives on ADHD
Throughout the past decade investigators have increasingly
embraced the notion that ADHD is best viewed within the con-
text of a developmental trajectory rather than that of a static
medical condition (Halperin and Schulz, 2006; Sagvolden et al.,
2005; Sonuga-Barke and Halperin, 2009; Taylor, 1999), and
63. notably,
that this developmental trajectory may be different for boys and
girls (Mahone and Wodka, 2008). It is through this developmen-
tal perspective that one is most likely to identify the mediators
and moderators of the diverse outcomes characteristic of youth
with ADHD. Compelling data support an array of hypotheses
that posit executive (Pennington and Ozonoff, 1996), motiva-
tional (Sonuga-Barke et al., 1992, 1996), inhibitory control
(Barkley,
1997), cognitive-energetic (Sergeant et al., 1999) and reward-
related (Sagvolden et al., 2005) deficits as being central to the
etiology of ADHD. More recently, it has been proposed that
there
may be multiple causal pathways that contribute to the
emergence
of ADHD in early childhood (Nigg et al., 2005; Sonuga-Barke,
2002).
However, little consideration has been afforded to pathways out
of ADHD or the mechanisms by which the severity of the
disorder

iminishes over time, which could serve as the conceptual basis
for
he development of novel, perhaps enduring, interventions.
In an attempt to explain the commonly observed diminu-
ion in ADHD symptoms across the lifespan, Halperin and
Schulz
2006), Halperin et al. (2008a) have posited distinct
neurocognitive
echanisms for the etiology of and relative recovery from ADHD.
pecifically, they hypothesized that ADHD is caused by non-
cortical
66. eural dysfunction that is present early in ontogeny and remains
elatively static throughout life. In this regard, the disorder is
never
eally “cured” or “out-grown.” Nonetheless, they posited that the
eduction of symptoms oftentimes seen over development are at
east partially accounted for by the degree to which prefrontally-
ediated EFs and other higher cortical functions, which emerge
hroughout childhood and adolescence, can compensate for these
ore primary and enduring subcortical deficits.
As such, the PFC and other cortical regions may be involved in
he reduction in severity of symptoms and impairment from
ADHD
ather than the etiology of the disorder. The efficiency of later
cor-
ical developmental processes may determine the extent to which
n individual can compensate for or have a diminution of ADHD
ymptoms. This hypothesis is consistent with data suggesting
that
rajectories of cortical development throughout middle childhood
ight be closely linked to ADHD outcomes (Shaw et al., 2006,
007b), and that lower reaction time variability is associated
with
ncreased activation of the prefrontal circuit (prefrontal cortex
and
audate) in children with ADHD (Suskauer et al., 2008). This
latter
nding was interpreted as prefrontal compensation for a more
pri-
ary motor deficiency. In addition, fMRI findings indicate that
PFC
67. ctivation in response to inhibition in adolescents with childhood
DHD corresponds to the persistence of symptoms, such that
those
ho are less symptomatic appear more like never-ADHD controls
Schulz et al., 2005a,b). Finally, longitudinal data (Halperin et
al.,
008b) examining neurocognitive functioning in adults who had
DHD in childhood, indicate that only those in whom ADHD has
ersisted differ from controls on measures of EFs such as
working
emory, sustained attention and inhibitory control.
This hypothesized developmentally-related compensation for
arlier deficits may also be related to changes in functional
onnectivity in the brain that occurs over development. For
exam-
le, Dosenbach et al. (2007) described two distinct “top-down”
unctional control networks in adults; a frontoparietal network
nvolved in adaptive online task control and a cinguloopercular
etwork involved in more stable set control. When compared
cross groups of children, adolescents and adults, a clear pat-
ern of developmentally-related differences emerged such that
hort-range connections associated with these networks
decreased
hereas long-range connections increased across development
Fair et al., 2007). These findings suggest greater segregation
etween networks as well as improved integration within net-
orks with increased age. It is possible that these developmental
rocesses that support the maturation of this dual-network con-
rol system play a critical role in the hypothesized compensation
or earlier deficits in youth with ADHD. Notably, this pattern of
evelopmental decreases in local connectivity and increases in
ong-range connectivity does not appear limited to these specific
68. eural systems. Rather, it appears to be a more general develop-
ental principle that operates throughout the brain (Fair et al.,
009; Supekar et al., 2009).
Finally, it has been hypothesized that the persistence of ADHD
nto adulthood, or the relative diminution of symptoms across
the
ifespan, is genetically mediated (Faraone, 2004). Supporting
this
ypothesis, Kuntsi et al. (2005) found in a longitudinal study of
000 twin pairs that symptom stability in ADHD from early-to-
id childhood was primarily due to shared genetic influences.
urther, at the molecular level, children with ADHD who had at
east one copy of the DRD4 7-repeat allele had a distinct trajec-
iobehavioral Reviews 35 (2011) 621–634 625
tory of cortical development characterized by normalized
cortical
thinning, were less likely to maintain a diagnosis of ADHD at
follow-
up, had higher IQs, and exhibited better global functioning than
children with ADHD without a DRD4 7-repeat allele; despite no
differences in ADHD symptoms at baseline. This is consistent
with
findings of Swanson et al. (Swanson et al., 2000) who reported
that
the presence of the DRD4 7-repeat allele in children with
ADHD
was associated with fewer neuropsychological deficits.
Addition-
ally, the presence/absence of the 7-repeat allele may also
underlie
69. a key gene × environment interaction in relation to ADHD, its
tra-
jectory, and potential treatment response. As compared to
children
without the DRD4 7-repeat allele, the behavior of those with a
7-repeat allele was found to be more sensitive to the quality of
par-
enting received (Sheese et al., 2007) and to have a better
treatment
response to a psychosocial parenting intervention (Bakermans-
Kranenburg et al., 2008). These data suggest that there may be
genetic differences in the degree to which both the environment
and delivered treatments influence developmental trajectories in
children.
Thus, from a developmental perspective, interventions that pro-
mote neural growth, functional connectivity, and lasting
cognitive
facilitation could potentially provide a fruitful avenue for novel
treatment approaches for this highly impairing oftentimes life-
long
disorder. Further, it is possible, that some children may be more
or less genetically susceptible to respond to such interventions.
As described below, accumulating evidence clearly indicates
that
early brain development is highly susceptible to environmental
influences.
5. Neural development
Human central nervous system development proceeds in a sys-
tematic manner that begins before conception and continues at
least into early adulthood. Nevertheless, brain development is
non-linear, and progresses in a localized and region-specific
man-
ner that coincides with functional maturation (Huttenlocher and
70. Dabholkar, 1997; Keshavan et al., 1994). Of particular
relevance
are the relatively late and protracted development of the basal
ganglia and cerebral cortex, including the PFC, and the motor
and
higher cortical functions that they mediate (Asato et al., 2010;
Barkovich, 2005; Barnea-Goraly et al., 2005; Benes, 1989;
Chelune
et al., 1986; Giedd et al., 1996, 1999; Gogtay et al., 2004;
Goldman,
1971; Goldman and Galkin, 1978; Huttenlocher and de Court,
1987;
Huttenlocher, 1990; Huttenlocher and Dabholkar, 1997; Hynd et
al., 1993; Keshavan et al., 1994; McKay et al., 1994; Mrzljak et
al.,
1990; Passler et al., 1985; Welsh et al., 1991; Yakovlev and
Lecours,
1967).
The human brain develops primarily in utero and is approxi-
mately 80% of adult size by the age of 2 years (Giedd et al.,
1999;
Kretschmann et al., 1986). The process of myelination also
begins
in utero and proceeds rapidly up to age 2 years (Brody et al.,
1987;
Kinney et al., 1988), but continues well into adolescence and
early
adulthood (Asato et al., 2010). The first two years of life are
also a
period of rapid synapse formation that occurs at varying times
and
rates in different brain regions, reaching maximum density at
age 3
months in the auditory cortex and at age 15 months in the PFC,
and
71. resulting in an overproduction of synapses (Huttenlocher and de
Court, 1987; Huttenlocher and Dabholkar, 1997).
Synaptogenesis
is followed by a plateau phase extending over several years,
during
which neurons begin to form complex dendritic trees (Mrzljak
et
al., 1990). These two processes seem to account for the increase
in
cortical gray matter in childhood found in MRI studies (Giedd
et al.,
1996, 1999; Gogtay et al., 2004; Shaw et al., 2006, 2007a).
Subsequent brain development, beginning at about 5 years of
age, is marked as much by cortical organization and refinement

s by neuronal growth. Cortical gray matter continues to thicken
uring the school-age years with about half of the cortical
regions
ttaining peak thickness by the median age of 7.5 years (Shaw
t al., 2007a), and cortical thickness peaking at around 10.2–12.8
ears in the parietal cortex and around 11.0–12.1 years in the
rontal lobe (Giedd et al., 1996, 1999; Gogtay et al., 2004).
Through-
ut this period the experience-dependent pruning of inefficient
ynapses in the cortex is also taking place (Giedd et al., 1996,
1999;
ogtay et al., 2004; Huttenlocher and de Court, 1987;
Huttenlocher
nd Dabholkar, 1997). Synaptic pruning progresses in a region-
pecific manner and eventually reduces synaptic density to 60%
f maximum (Huttenlocher and de Court, 1987; Huttenlocher
nd Dabholkar, 1997), although it is mostly after puberty that
he developmental process of cortical thinning occurs. These
pro-
74. esses all facilitate efficient neural transmission and are
necessary
or the functional maturation of the brain. As in humans, this
lateau phase of cortical thickness lasts through puberty in mon-
eys and is thought to be indicative of the need for consistent
nd high synaptic density during the formative years when learn-
ng and experiences are most intense (Bourgeois et al., 1994).
hile much of neural development is likely to be genetically
rogrammed, considerable data indicate that variability in devel-
pment across the lifespan is at least in part related to one’s
xperiences.
.1. Environmental influences on neurodevelopment
The notion that life experiences and one’s environment can
nfluence both cognitive and neural development was first
clearly
rticulated in 1949 by Hebb (Hebb, 1949), who postulated that
ynapses are strengthened when presynaptic fibers repeatedly
articipate in activating the postsynaptic neuron. Subsequently,
ubel and Wiesel’s (Hubel and Wiesel, 1970; Wiesel and Hubel,
965) classic experiments demonstrated environmental influences
n neural plasticity and neurodevelopment in the visual system
n cats. In the 1960s Rosensweig and colleagues (Rosenzweig
t al., 1962, 1968; Rosenzweig, 1966; Rosenzweig and Bennett,
969) systematically began to examine the influence of environ-
ental manipulations on brain weight, cortical thickness and the
tructure of dendrites, as well as on cognitive functioning. In the
970 s, Greenough et al. (1973, 1978), Greenough and Volkmar
1973) expanded this work to include the effects of
environmental
nhancements on a range of parameters of brain function
including
endritic branching, spine density, synaptogenesis, angiogenesis,
75. nd gliogenesis.
Since these early seminal studies, an abundant scientific liter-
ture, primarily, but not exclusively, in non-human species, has
xamined the impact of environmental influences on molecular
nd cellular aspects of neural development as well as on an array
f behavioral and cognitive functions. The precise environmen-
al manipulations required to best facilitate specific aspects of
eural development, the critical periods in development when
hey are optimally applied, and the duration necessary for such
nterventions have remained somewhat elusive. However, there
s no longer doubt that brain development is highly respon-
ive to increased levels of physical activity/exercise as well as
nvironmental enrichment. While a full review of this extensive
iterature is beyond the scope of this paper, a brief overview is
arranted. A plethora of studies in rodents have shown that envi-
onmental enrichment increases neuronal size, dendritic
branching
nd spine number, synaptic density and overall neurotransmis-
ion in the neocortex (Diamond et al., 1964; Diamond, 1967;
lobus et al., 1973; Green and Greenough, 1986; Greenough et
l., 1973, 1978; Greenough and Volkmar, 1973; Leggio et al.,
005; Rosenzweig and Bennett, 1996). Environmental
enrichments
lso enhance neurogenesis (Kempermann et al., 1998; Nilsson et
iobehavioral Reviews 35 (2011) 621–634
al., 1999), long-term potentiation (LTP; Duffy et al., 2001),
neu-
rotrophin levels (Ickes et al., 2000; Pham et al., 1999, 2002),
dendritic spine growth and branching (Faherty et al., 2003;
Green
et al., 1983; Rampon et al., 2000), synaptophysin levels (Frick
76. and Fernandez, 2003; Nithianantharajah et al., 2004), and nerve
growth factor mRNA and CREB gene expression (Torasdotter et
al., 1996, 1998; Williams et al., 2001) in the dentate gyrus of
the
hippocampus. Consistent with the effects of environmental
enrich-
ment on neurodevelopment, numerous studies have shown that
it significantly improves performance on an array of spatial and
nonspatial memory tasks in rats (Leggio et al., 2005; Nilsson et
al., 1999) and mice (Kempermann et al., 1997; Williams et al.,
2001).
Evidence for the impact of environmental enrichment in
humans is far more limited and centers largely on the concept
of ‘cognitive reserve’ as related to the emergence of
Alzheimer’s
disease. Epidemiologic data provide a compelling link between
increased participation in intellectual and social activities in
daily
life and a slower cognitive decline in the elderly (Scarmeas and
Stern, 2004). Furthermore, cognitive exercises show promise as
effective interventions for slowing the trajectory of cognitive
and
functional decline that is associated with dementia (Gates and
Valenzuela, 2010).
In addition to environmental enhancements, physical exercise,
most commonly in the form of wheel running in rodents, has
also
been shown to enhance neural growth and development, as well
as associated behavioral and cognitive functions. Physical exer-
cise increases levels of synaptic proteins (Vaynman et al.,
2006),
glutamate receptors (Farmer et al., 2004) and the availability of
brain-derived neurotrophic factor (BDNF) (Berchtold et al.,
2005)
77. and insulin-like growth factor-1 (Trejo et al., 2001), all of
which can
enhance neural plasticity. Specifically, treadmill exercises in
rats
increase cell proliferation via insulin-like growth factor-1
(Trejo
et al., 2001) and cell proliferation and survival in the dentate
gyrus
(van Praag et al., 1999b). These neural changes in response to
phys-
ical exercise are accompanied by behavioral changes such that
physical exercise enhances spatial learning (Fordyce and Farrar,
1991; Fordyce and Wehner, 1993) and passive avoidance
memory
(Samorajski et al., 1985).
Physical exercise has also been reported to increase BDNF lev-
els (Ferris et al., 2007; Gold et al., 2003; Rasmussen et al.,
2009;
Seifert et al., 2010; Strohle et al., 2010; Tang et al., 2008;
Zoladz
et al., 2008), enhance cognitive performance (Baker et al.,
2010;
Ferris et al., 2007; Laurin et al., 2001), and to promote brain
health
(Colcombe et al., 2003) in human adults. One study that
examined
BDNF levels in children with ADHD reported that as compared
to
controls, those with ADHD had increased levels of BDNF, and
that
BDNF levels correlated with neuropsychological performance as
indicated by number of errors on a continuous performance test
(Shim et al., 2008). However, BDNF change in response to
exercise
was not assessed.
78. Exercise and environmental enhancements also have been
shown to have a positive effect on outcome in several animal
mod-
els of neurodevelopmental disorders. Wheel running from an
early
age delays the onset of motor deficits in knock-out mouse mod-
els of Huntington’s disease (van Dellen et al., 2008), and
complex
motor training in rats enhances synaptogenesis in the motor cor-
tex and motor coordination following lesions of the
sensorimotor
cortex (Jones et al., 1999). Perhaps more relevant to the current
thesis, chronic exercise blunted the developmental rise of blood
pressure while increasing glutamic acid decarboxylase mRNA in
the
caudal hypothalamus in spontaneously hypertensive rats, which
are commonly used as an animal model for ADHD (Little et al.,
2001). Finally, rat pups born from alcohol-intoxicated mothers

ill exercise not only enhances c-Fos activity in the hippocampus
Sim et al., 2008), but exercise and various forms of
environmen-
al enrichment reduce the severity of behavioral deficits
associated
ith maternal alcohol intoxication (Hannigan et al., 2007). Thus,
t least in animals, interventions involving environmental enrich-
ent and physical exercise can yield lasting positive effects on
81. ehavioral anomalies due to both genetic and environmental
tiologies.
Most rodent studies focusing on environmental enrichments
mploy a combination of social (e.g., multiple animals in a
cage),
ognitive (e.g., toys, tunnels) and motor (e.g., running wheels)
stim-
li. As such, it is difficult to determine the extent to which any
ne of these contributes to the positive outcome. Data suggest
that
oth exercise and environmental enhancement contribute to posi-
ive neurodevelopmental outcomes, although not necessarily in
an
dentical manner. Some evidence suggests that exercise affects
the
rain similarly to environmental enrichment, with changes
includ-
ng enhanced hippocampal LTP (Kim et al., 2004) and
neurogenesis
van Praag et al., 1999a,b), as well as increased hippocampal and
eocortical neurotrophin mRNA expression (Neeper et al., 1995,
996). Other studies suggest that individual elements may have
ifferent effects on neural plasticity and development. Manipula-
ions involving problem solving and coordination increase
synapse
ormation in the cerebellar cortex (Kleim et al., 1997, 1998),
hereas repetitive physical exercise increases cerebellar blood
ves-
el density (Black et al., 1990). Exercise has also been found to
mprove spatial memory and preserve cognitive function in aging
ats (Anderson et al., 2000; Fordyce and Farrar, 1991) and mice
Anderson et al., 2000; Fordyce and Wehner, 1993; van Praag et
l., 1999a). Nevertheless, some data (Faherty et al., 2003)
82. suggest
hat environmental enhancements are more effective for facilitat-
ng neural changes than exercise alone, while others (Lambert et
al.,
005) suggest that exercise, but not cognitive stimulation
improves
patial memory.
Thus, preclinical data indicate that environmental enhancement
nd exercise have positive morphological, chemical and
cognitive
ffects on the brain across the lifespan. Much of the human lit-
rature, with moderate success, has focused on the latter end of
he developmental spectrum, with the aim of addressing cogni-
ive declines characteristic of the elderly. These data suggest
that
ognitive and social stimulation, as well as physical exercise,
may
elay the onset of dementia and other neurodegenerative dis-
ases (Scarmeas and Stern, 2004; Ravaglia et al., 2008; Kramer
and
rickson, 2007; Arkin, 2007; Rolland et al., 2007). Furthermore,
in
dults, cognitive training increases cortical brain activity (Olesen
t al., 2004) and alters dopamine D1 receptor binding in both the
refrontal and parietal cortices (McNab et al., 2009).
Although early childhood is the period of greatest neural plas-
icity, and the most prominent cell proliferation in response to
xercise has been shown to occur at younger ages in rats (Kim et
l., 2004), far less research has been conducted with children.
Two
tudies have examined exercise regimes in children with ADHD;
ne reporting a blunted catecholamine response (Wigal et al.,
2003)
nd the other showing changes in eye blink responses and reduc-
