Introduction
Safety is an important aspect of human lives of all ages, and its
achievement and sustenance is being aimed at globally. Those
vulnerable most in this case are the young children and the
adolescents, who are still dependent on parents and guardians to
keep them healthy and safe. The wellbeing is when an
individual is safe and healthy, and is part and parcel of the
quality of life. This wellbeing also includes mental health, when
an individual can also fulfill their goals, both social and
personal, and general wellbeing includes aspects such as
income, education, general health and safety as objective
measures, and also aspects such as happiness, satisfaction and
quality of life. The aspect of children and adolescent wellbeing,
both physically and mentally, is therefore important, as it will
factor in an individual’s well being when they grow up, and
therefore a stable, safe and healthy childhood and adolescent is
very crucial for any generation. There are several factors to be
looked at when dealing with child and adolescent well being,
and they include education, culture, gender, family and
parenting (Kahl, Dortschy & Ellsasser, 2007).
Health and Well-Being
The measures for physical health include self reported health,
child mortality, infant mortality, birth weight, breastfeeding,
immunization, hearing and vision, height and weight, chronic
conditions, development process and dental health. The healthy
behavior and lifestyle include things such as non intentional
accidents, safety behaviors, physical activity, injuries and
exercises. Some measures that promote healthy childhood and
adolescent life include things such as immunization, as it lowers
the child mortality and also gives them strong health
advantages. Globally, the percentage of death contributed by

unintentional injury is very large, and presence of healthy
behaviors can reduce this percentage significantly (Fauth &
Thompson, 2009).
Safety Regulations
Over the past few decades, the regulations regarding safety
and health of children and adolescents have increased, and
measures have been put in place by governments globally,
although they differ in legislation and enforcement. Some of the
interventions include the introduction of the requirement for
minimum age fro drinking, where minors aren’t allowed to drink
alcohol. Novice drivers are also regulated regarding the blood
alcohol concentration. Laws regarding wearing of helmets when
riding bicycles and motorcycles have also been introduced.
Laws regarding seat belts, helmets and child restraint are also
being enforced, and did not exist when we were growing up.
Regulations regarding speed limits around children play areas,
schools and residential areas have also been introduced.
Systems regarding Graduated driver licensing have also been
enforced to try and curb the road accidents (CDC, 2012).
When it comes to the risk of drowning for children and
adolescents, several regulations have also been introduced,
which include the covering or removal of water hazards,
sufficient (four side) fencing around swimming pools,
availability of standby resuscitation and also wearing of
floatation devices. When it comes to the risk of burns,
regulations regarding smoke alarms, installation of burn centers,
child resistant lighters and also laws regarding water
temperatures are also being enforced now (Harvey et al, 2009)
The risk factor of falling from heights for children and
adolescents has also been regulated, where laws regarding
designs of childcare facilities and learning institutions, e.g.
furniture designs and other products are now being enforced.
The playground standards have also been established, regarding
maintenance of equipment, height of equipment, surface
material, window guards and several community programs are
now being enforced. Laws regarding poisoning do exist now,

and include aspects like the removal of toxic agents, packaging
of several products that may be poisonous like medicine,
packaging quantities that will not be lethal and also the
installation of poison control centers are now being enforced
too (Harvey et al, 2009).
All these legislations and safety measures like the requirement
to have protective helmets, seat belts and child passenger
restraints have greatly reduced the mortality rates through road
accidents. The legislation covering domestic injury risks like
smoke alarms, four side fencing of swimming pools, removal of
water hazards among others have also reduced the domestic
injuries reported. Regulations regarding poisoning like the child
resistant packaging and child resistant lighters have also greatly
reduced deaths and injuries from these risk factors, and
establishment of poison centers and also burn centers have
worked to reduce the severity of the injuries (Harvey et al,
2009).
Injury Statistics
The injury risk differ from toddlers, children and adolescents,
because of their level of activity and also their physical
coverage, as adolescents roamed more than the toddlers or small
children. Studies have been carried out to ascertain the injury
statistics among toddlers, children and adolescents. One
particular study carried out a research among 6,813 parents
where they were asked to give some data on their child safety
measures. It was found out that within a period of twelve
months when the study was carried out, 15.9% of the children
had suffered at least one injury. Of this percentage, 15.2% of
them were due to accidents and only 0.8% was as a result of
assault. When it comes to the factor of gender, it was found out
that boys suffered more injuries, with 17.9% being boys, as
opposed to girls who had a percentage of 14% (CDC, 2012).
In a study of 2,410 injured children, 13.3% of them were
hospitalized, and among toddlers, two thirds of them were
accidents that occurred domestically, and among the adolescents
aged five to twelve, 32.1% of the injuries were from activities

such as sports and leisure. Among the adults aged 15 to 17,
38.9% of the injuries were from sports and other leisure
activities. From infancy when a child is growing up to school
going age, the number of accidents do rise significantly, and in
day care facilities and school, the number of accidents tripled,
from 10.9% to 28.7%, and the traffic accidents between these
periods also tripled from 5.6% to 16.7% (CDC, 2012).
Three injury mechanisms stood out to be counted as notorious
for toddlers, children and adolescents. One of the mechanisms
was falling on level ground, where 35.2% of injuries were from
falling on level ground. The other mechanism is falling from
heights, through which 25.2% of toddlers, children and
adolescents suffered injuries, the toddlers faced highest risk in
this mechanism. The third mechanism is collision, either with
other people or objects, and this contributed to 20.6% of the
injuries, especially in toddlers. The risk levels of these three
mechanisms differed with age, as small children were at the
highest risk, 35.8%, from falling from heights. In adolescents,
the risk factor from strains, sprains and contusions rose to
50.9%, becoming the highest risk factor for this age group. The
risk from bone fractures for toddlers increased from 10.7%
during toddlerhood to 21.8% in adolescent age. The factor of
socio economic status on injuries was not found in the study,
but for traffic accidents, children from a lower socio economic
status were at a higher risk than those children from a higher
socio economic status as they suffered more traffic accidents
(Statham & Chase, 2010).
