  ASSESSMENT OF GROWTHIN INFANTS, CHILDREN AND ADOLESCENTS INCLUDING WHO STANDARD AND INDIAN STANDARD PARAMETERS
• 2.
  WHAT IS GROWTH? •Growth is a quantitative increase in the physical size of the body, resulting from an increase in: • Cell number (Hyperplasia) • Cell size (Hypertrophy) • Intercellular substance • It is measured objectively using anthropometric parameters
• 3.
  CHARACTERISTICS • Measurable • Continuousprocess • Influenced by genetic and environmental factors • Maximum during fetal life and infancy • Examples • Increase in body weight • Increase in body length • Increase in head circumference • Increase in muscle mass
• 4.
  GROWTH REFLECTS: • • Nutritionalstatus • General health • Endocrine function • Genetic potential
• 5.
  GROWTH VS DEVELOPMENT GrowthDevelopment Quantitative Qualitative Increase in body size Functional maturation Measured in cm/kg Measured by milestones Objective Subjective Ends after adolescence Continues throughout life Example:- Growth Height increased from 100 cm to 110 cm Development Child learns to speak, walk, write, and think.
• 6.
  PRINCIPLES OF NORMALGROWTH:- 1. Predictable Pattern of Growth Growth follows a definite and orderly pattern from birth to adulthood. Although the rate varies with age, the sequence of growth remains consistent in healthy children. 2. Growth Occurs in Stages The fastest growth occurs during infancy and adolescence. Growth velocity slows during childhood and increases again during the pubertal growth spurt. 3. Different Body Parts Grow at Different Rates Various organs and body systems grow at different speeds. For example, the brain grows rapidly in early childhood, whereas the reproductive organs grow mainly during puberty. 4. Growth is Influenced by Multiple Factors Normal growth depends on adequate nutrition, genetic potential, hormonal balance (growth hormone, thyroid hormone, insulin, and sex hormones), good health, and a supportive environment. Regular monitoring helps detect growth abnormalities early.
• 7.
  SCAMMON’S GROWTH CURVE:- Scammon’scurves Depicting differential growth Not all tissue systems of the body grow at the same rate Neural tissue growth is completed by 6-7 years Lymphoid tissue growth is completed in late childhood and growth of genital tissues accelerates at the same time. General Body tissue follows S-Shaped curve. Growth of general body tissues which include muscles, bones & viscera show “S shaped curve” have slow rate of growth during childhood and accelerated rate of growth during puberty
• 8.
  FACTORS AFFECTING GROWTH •Growth is influenced by a combination of genetic, biological, nutritional, environmental, and psychosocial factors. • 1. Genetic Factors • Determine the child’s growth potential. • Influence height, body build, and growth pattern. • 2. Nutritional Factors • Adequate proteins, calories, vitamins, and minerals are essential. • Malnutrition causes stunting and underweight.
• 9.
  FACTORS AFFECTING GROWTH 3.Hormonal Factors Growth Hormone (GH) Thyroid hormone Insulin Sex hormones during puberty 4. Environmental & Health Factors Recurrent infections Chronic diseases Socioeconomic status
• 10.
  IMPORTANCE OF GROWTHASSESSMENT • Growth assessment is a simple, non-invasive method to evaluate a child’s health and nutritional status. • Importance • Detects growth disorders at an early stage. • Assesses nutritional status. • Identifies undernutrition, overweight, and obesity. • Monitors physical development. • Evaluates response to treatment. • Helps in planning preventive and public health programs. • Clinical Significance • Essential during every pediatric visit. • Supports early intervention for better outcomes.
• 11.
  ANTHROPOMETRIC MEASUREMENTS:- • Anthropometryrefers to the systematic measurement of the human body to assess growth, development, and nutritional status. It is a simple, reliable, and widely used method for monitoring child growth. • Major Anthropometric Parameters • Weight: The most sensitive indicator of current nutritional status and recent growth changes. • Length/Height: Reflects linear growth and helps detect chronic malnutrition (stunting). • Head Circumference: Assesses brain growth and helps identify conditions such as microcephaly and hydrocephalus. • Chest Circumference: Used to evaluate body growth; after one year of age, it normally exceeds head circumference. • Mid Upper Arm Circumference (MUAC): A quick screening tool for detecting acute malnutrition in children aged 6–59 months. • Body Mass Index (BMI): Indicates whether a child is underweight, normal weight, overweight, or obese based on weight relative to height.
• 12.
  ANTHROPOMETRIC MEASUREMENTS:- • SkinfoldThickness: Measures subcutaneous fat stores and estimates body fat percentage. • Arm Span: Useful for assessing skeletal growth and detecting body proportion abnormalities when height measurement is difficult. • Sitting Height: Evaluates the growth of the trunk and helps assess body proportions and skeletal development.
• 13.
  WEIGHT ASSESSMENT Equipment Infant weighingscale (0–2 years) Digital weighing machine (>2 years) Procedure Remove shoes and heavy clothing. Infant should be weighed without clothing or diaper if possible. Record weight to the nearest 10 g (infants) or 100 g (older children). • Clinical Importance • Best indicator of nutritional status. • Detects growth faltering early. • Useful for drug dose calculation. Normal Weight Gain Birth weight: 2.5–3.5 kg Doubles by 5 months Triples by 1 year Quadruples by 2 years
• 14.
  LENGTH AND HEIGHTASSESSMENT • 1. Length and Height Measurement • Length is measured from birth to 2 years of age in the supine (lying) position using an infantometer. After 2 years of age, height is measured in the standing position using a stadiometer. Accurate measurement is essential for evaluating normal growth and identifying growth abnormalities. • 2. Average Linear Growth • A healthy newborn has an average length of about 50 cm at birth. This increases to approximately 75 cm by 1 year and 87 cm by 2 years. After infancy, children grow at an average rate of 5–7 cm per year until the onset of puberty, when another growth spurt occurs. • 3. Clinical Importance • Length and height are reliable indicators of linear growth and long-term nutritional status. Regular monitoring helps detect stunting, chronic malnutrition, endocrine disorders, and other growth abnormalities, allowing timely intervention and appropriate management.
• 16.
  HEAD CIRCUMFERENCE (HC) •Head circumference (Occipitofrontal Circumference, OFC) is the maximum circumference of the head and reflects brain growth, especially during the first 2 years of life. • Measured using a non-stretchable measuring tape. • Tape passes over the supraorbital ridges anteriorly and the most prominent occipital protuberance posteriorly. • Record to the nearest 0.1 cm. • It Detects microcephaly • It Detects macrocephaly/hydrocephalus • Assesses brain growth Age Head Circumference Birth 34–35 cm 6 months 43 cm 1 year 46 cm Adult 54–55 cm
• 17.
  HEAD CIRCUMFERENCE
• 18.
  CHEST CIRCUMFERENCE • Chestcircumference is measured at the nipple line during quiet respiration to assess physical growth and nutritional status. The average chest circumference at birth is 32–33 cm, which is normally less than head circumference. By 1 year of age, chest circumference becomes greater than head circumference, reflecting normal growth. A delayed increase in chest circumference may suggest chronic malnutrition or long-standing illness. (WHO Child Growth Standards; IAP Growth Monitoring Guidelines) • Birth: HC > CC • After 1 year: CC > HC

  MID UPPER ARMCIRCUMFERENCE (MUAC) • MUAC is measured midway between the acromion and olecranon of the left arm • Used for children 6–59 months.. MUAC Interpretation ≥12.5 cm Normal 11.5–12.4 cm Moderate Acute Malnutrition (MAM) <11.5 cm Severe Acute Malnutrition (SAM)
• 21.
  BODY MASS INDEX(BMI) • Formula • BMI = Weight (kg) ÷ Height² (m²) • Uses • Screening for overweight and obesity. • Assesses nutritional status. • Compared using BMI-for-age percentiles in children. • Clinical Importance • Detects obesity-related health risks. • Monitors long-term nutritional status.
• 22.
  SKINFOLD THICKNESS &OTHER MEASUREMENTS • Skinfold Thickness: • Skinfold thickness is measured using a skinfold caliper, usually at the triceps and subscapular regions, to estimate subcutaneous fat and body fat percentage. It helps assess energy reserves and is useful in detecting both undernutrition and obesity. • Other Measurements: • Additional anthropometric measurements include arm span, sitting height, and the upper segment : lower segment (US:LS) ratio, which help evaluate skeletal growth, body proportions, and identify conditions such as skeletal dysplasias and endocrine disorders. These measurements are especially valuable when height and weight alone are insufficient to assess a child’s growth and nutritional status.
• 23.
  GROWTH CHARTS • Growthcharts are graphical representations used to assess and monitor a child’s physical growth by plotting anthropometric measurements against age. They provide a simple method of comparing an individual child’s growth with standard reference values and help identify deviations from normal growth at an early stage. • Uses • Monitor growth over time. • Assess nutritional status. • Detect growth abnormalities early.
• 24.
  WHO GROWTH STANDARDS •The WHO Child Growth Standards (2006) describe the normal pattern of growth in children from birth to 5 years of age. They are based on healthy children living under favourable environmental conditions and receiving appropriate nutrition. These standards are used worldwide for assessing child growth • Parameters Included • Weight-for-age • Length/Height-for-age • Weight-for-length/height • BMI-for-age • Head circumference-for-age.
• 25.
  WHO Z-SCORE SYSTEM •The WHO recommends the use of Z-scores (Standard Deviation Scores) for interpreting growth measurements. A Z-score indicates how far a child’s measurement lies above or below the median of the reference population. It provides a reliable method for identifying undernutrition, overweight, and growth disorders. • Interpretation • −2 SD to +2 SD: Normal growth • Below −2 SD: Moderate malnutrition • Below −3 SD: Severe malnutrition • Above +2 SD: Overweight/Obesity
• 26.
  WHO GROWTH INDICATORS •Different growth indicators are used to assess various aspects of a child’s nutritional and physical development. Each indicator has a specific clinical significance and helps in identifying different forms of malnutrition. • Weight-for-age: Assesses underweight. • Height-for-age: Identifies stunting due to chronic malnutrition. • Weight-for-height: Detects wasting caused by acute malnutrition. • BMI-for-age: Screens for overweight and obesity. • Head circumference-for-age: Reflects brain growth during early childhood.
• 27.
  Weight-for-Age Growth Chart(Birth–5 Years) Plots a child’s weight against age using WHO reference standards. The 50th percentile represents the average weight for age. Normal growth is indicated when the child follows the same percentile curve over time. Weight below the 3rd percentile suggests undernutrition or growth faltering and requires evaluation. Weight above the 97th percentile may indicate overweight or obesity and should be assessed clinically.

  COMPARISON OF WHOAND IAP GROWTH STANDARDS • The WHO Growth Standards are recommended for children from birth to 5 years and represent optimal growth under ideal health and nutritional conditions. For children aged 5–18 years, the Indian Academy of Pediatrics (IAP) growth charts are preferred as they are based on data from healthy Indian children and better reflect the growth pattern of the Indian population. WHO Standards IAP Standards Birth–5 years 5–18 years International reference Indian reference Uses Z-scores Uses percentiles Recommended globally Recommended in India
• 40.
  GROWTH MONITORING SCHEDULE •Regular growth monitoring helps assess a child’s health, nutrition, and development. Measurements should be recorded periodically and plotted on the appropriate growth chart to identify any deviation from the normal growth pattern. • Recommended Schedule • Birth to 1 year: Every month • 1–2 years: Every 3 months • 2–5 years: Every 6 months • 5–18 years: At least once every year • Importance • Early detection of growth faltering. • Timely nutritional and medical intervention. • Continuous assessment of growth trends.
• 41.
  ASSESSMENT OF NUTRITIONALSTATUS • Growth assessment plays an important role in evaluating the nutritional status of children. Anthropometric measurements, when interpreted using standard growth charts, help identify different forms of malnutrition. • Common Indicators • Underweight: Low weight for age. • Stunting: Low height for age, indicating chronic malnutrition. • Wasting: Low weight for height, indicating acute malnutrition. • Overweight/Obesity: High BMI for age. • These indicators help in planning appropriate nutritional and therapeutic measures.
• 42.
  COMMON GROWTH DISORDERS •Growth disorders occur when a child does not grow according to the expected pattern. They may result from nutritional deficiencies, endocrine disorders, chronic illnesses, or genetic conditions. • Common Disorders • Short stature: Height below the expected range for age. • Stunting: Chronic impairment of linear growth. • Wasting: Acute loss of body weight. • Failure to thrive: Poor weight gain over time. • Obesity: Excessive body weight due to increased fat accumulation. • Early diagnosis and management are essential to prevent long-term complications.
• 43.
  GROWTH ASSESSMENT INTHE NEWBORN • Assessment of growth at birth is an essential component of neonatal examination. It provides valuable information regarding fetal growth, intrauterine nutrition, and gestational maturity. Birth weight, gestational age, and weight in relation to gestational age are the principal parameters used to classify newborns and identify those at increased risk of morbidity and mortality. • Classification According to Birth Weight:- Category Birth weight Normal Birth Weight (NBW) ≥2500 g Low Birth Weight (LBW) <2500 g Very Low Birth Weight (VLBW) <1500 g Extremely Low Birth Weight (ELBW) <1000 g
• 44.
  • Small forGestational Age (SGA): Birth weight below the 10th percentile for gestational age. • • Appropriate for Gestational Age (AGA): Birth weight between the 10th and 90th percentile. • • Large for Gestational Age (LGA): Birth weight above the 90th percentile. Clinical Significance: Identification of SGA and LGA infants helps in anticipating complications such as hypoglycaemia, birth trauma, hypothermia, and respiratory problems.
• 45.
  INTRAUTERINE GROWTH RESTRICTION(IUGR) • Intrauterine Growth Restriction (IUGR) refers to a condition in which the fetus fails to attain its genetically determined growth potential due to various maternal, placental, or fetal factors. IUGR is associated with increased perinatal morbidity and mortality and requires careful assessment immediately after birth. • Types of IUGR • Symmetrical IUGR:- • Reduction in weight, length, and head circumference. • Results from insults occurring during early pregnancy. • Common causes include chromosomal abnormalities, congenital infections, and severe maternal malnutrition. • Asymmetrical IUGR:- • Birth weight is disproportionately reduced, while head circumference is relatively preserved (“head-sparing”). • Usually develops during the third trimester due to placental insufficiency, pregnancy-induced hypertension, or maternal undernutrition.
• 46.
  Symmetric vs Asymmetric IUGR

  ASSESSMENT OF GESTATIONALAGE • Assessment of gestational age is an important part of neonatal examination, as it helps determine the maturity of the newborn and guides clinical management. Although gestational age is usually calculated from the first day of the mother’s last menstrual period (LMP) or by first-trimester ultrasonography, these details may not always be available or reliable. In such situations, clinical assessment of maturity becomes essential • The New Ballard Score (NBS) is the most commonly used clinical method for estimating gestational age. It can be applied to both preterm and term infants and is most accurate when performed within the first 24–48 hours after birth. The score is obtained by assessing six physical and six neuromuscular signs of maturity. The total score is then converted into the estimated gestational age in weeks.
• 48.
  ASSESSMENT OF GESTATIONALAGE • Physical Maturity Criteria • Skin texture and opacity • Presence of lanugo hair • Plantar creases • Breast tissue development • Eye and ear cartilage • Development of external genitalia (male/female) • Neuromuscular Criteria • Posture • Square window (wrist flexibility) • Arm recoil • Popliteal angle • Scarf sign • Heel-to-ear maneuver
• 49.
  CLINICAL APPLICATIONS • • Estimationof gestational age when obstetric dates are uncertain. • Differentiation between preterm, term, and post-term infants. • Identification of infants at risk for complications related to prematurity. • Appropriate interpretation of birth weight using gestational age charts (SGA, AGA, and LGA). • Planning neonatal care and follow-up. Clinical Pearl: The New Ballard Score is considered the standard bedside method for estimating gestational age in newborns when reliable obstetric dating is not available, and it complements growth assessment by helping classify infants as SGA, AGA, or LGA accurately.

  CASE-BASED GROWTH CHARTINTERPRETATION • Case Study • A 2-year-old boy is brought to the pediatric outpatient department for poor weight gain. On examination: • Age: 2 years • Weight: 8.5 kg • Height: 82 cm • MUAC: 11.8 cm • When plotted on the WHO Growth Chart: • Weight-for-age is below −2 SD. • Height-for-age is below −2 SD. • Weight-for-height is within the normal range.
• 52.
  CASE-BASED GROWTH CHARTINTERPRETATION • Interpretation • The child is underweight and stunted, suggesting chronic undernutrition. The MUAC indicates Moderate Acute Malnutrition (MAM). Nutritional assessment, dietary counselling, and regular follow-up are required.
• 53.
  GROWTH ASSESSMENT VSDEVELOPMENTAL ASSESSMENT • Growth Assessment • Growth refers to an increase in body size and is assessed by anthropometric measurements such as weight, height, head circumference, and BMI. • Developmental Assessment • Development refers to the acquisition of functional abilities and milestones. It is assessed using standardized developmental screening tools, the most common being the Denver Developmental Screening Test (DDST-II). Growth Development Physical increase Functional maturation Anthropometry Developmental milestones WHO/IAP charts Denver Test
• 54.
  DEVELOPMENTAL ASSESSMENT ANDDENVER METHOD • Developmental assessment is the systematic evaluation of a child’s functional abilities and achievement of age-appropriate milestones. Unlike growth assessment, which measures physical size, developmental assessment evaluates the maturation of the nervous system and the acquisition of motor, language, social, and adaptive skills. • The Denver Developmental Screening Test-II (DDST-II) is one of the most widely used screening tools for assessing developmental milestones in children from birth to 6 years of age. It helps identify children who may have developmental delays and require further evaluation.
• 55.
  DENVER DEVELOPMENTAL SCREENINGTEST (DDST-II) • The Denver Developmental Screening Test-II (DDST-II) is a standardized developmental screening tool developed by William K. Frankenburg and Josiah B. Dodds. It was first introduced in 1967 and later revised as DDST-II in 1992. • The test contains 125 developmental items arranged according to the age at which 25%, 50%, 75%, and 90% of children are expected to perform each task. • Purpose • Detect developmental delay at an early stage. • Identify children needing further assessment. • Monitor developmental progress over time. • Assist in planning early intervention.
• 56.
  DOMAINS OF DENVERTEST:- • Four Developmental Domains • The DDST-II evaluates development in four major domains. Domain Examples Personal–Social Smiles, feeds self, dresses, interacts with others Fine Motor–Adaptive Grasps objects, stacks blocks, copies shapes, draws Language Babbles, speaks words and sentences, follows commands Gross Motor Rolls over, sits, crawls, walks, runs, jumps
• 57.
  Personal Social: Tracksinteractive behavior, self-care routines, and environmental adjustment milestones from infancy up to 6 years of age. Fine Motor-Adaptive: Evaluates hand-eye coordination, fine- muscle tasks, and cognitive problem-solving abilities such as block building and copy drawing. Chronological Timeline: The horizontal axis is precisely divided into Months (2 to 24) and seamlessly transitions into Years (3 to 6) Developmental Milestones: Tasks are represented by horizontal, multi-shaded rectangular bars positioned along the age-scale timeline Progressive Shading: Each bar segments child population achievements. Shading transitions denote thresholds at 25%, 50%, 75%, and finally 90% of the population Clinical Utility: Helps pediatric clinicians instantly identify delayed milestones if a chid fails a task that 90% of peers their age have already mastered.
• 58.
  ADMINISTRATION AND INTERPRETATION •Administration • The child’s chronological age is calculated accurately and marked on the Denver test chart. Tasks appropriate for the child’s age are administered, and performance is recorded. • Interpretation • Normal: No delays and a maximum of one caution. • Suspect: One or more delays or two or more cautions. • Untestable: Child refuses one or more items that fall completely to the left of the age line. • Advantages • Easy to administer. • Takes approximately 20–30 minutes. • Requires minimal equipment. • Suitable for outpatient and community settings. • Limitation • The DDST-II is a screening test and should not be used as the sole basis for diagnosis
• 59.
  CLINICAL IMPORTANCE • TheDenver Developmental Screening Test is useful for: • Early detection of developmental delays. • Monitoring high-risk infants and children. • Assessing developmental progress during follow-up. • Guiding referral for specialized evaluation and rehabilitation. • Supporting early intervention programs to improve long-term outcomes.
• 60.
  OTHER DEVELOPMENTAL SCREENINGTOOLS • Developmental screening can be performed using several standardized tools. The choice depends on the child’s age, purpose of assessment, and clinical setting. Tool Age Group Use Denver Developmental Screening Test-II (DDST-II) Birth–6 years General developmental screening Trivandrum Development Screening Chart (TDSC) Birth–6 years Rapid developmental screening in India Ages and Stages Questionnaire (ASQ) 1 month–5½ years Parent-completed developmental screening Bayley Scales of Infant Development (BSID) 1–42 months Detailed assessment of cognitive, language, and motor development

  IMPORTANT DEVELOPMENTAL MILESTONES
• 62.
  GROWTH VELOCITY • Growthvelocity refers to the rate of increase in a child’s height over a specific period. It is one of the most sensitive indicators of normal growth and helps detect growth disorders at an early stage. Age Growth Velocity Birth–1 year 25 cm/year 1–2 years 12 cm/year 2–4 years 7–8 cm/year 4 years–Puberty 5–6 cm/year Puberty 8–12 cm/year • Clinical Importance • Detects growth failure early. • Assesses response to treatment. • Useful in endocrine and chronic diseases.
• 63.
  Y-Axis: Growth rate(velocity) in mm/year. X-Axis: Age in years. Infancy (0–4 years): Starts extremely high (over 200 mm/year) and decelerates rapidly. Childhood (4–10 years): Stabilizes into a steady, flat rate of growth. Pre-pubertal Dip (~11 years): Growth slows down to its lowest point right before puberty. Pubertal Growth Spurt (~12–14 years): Sharply spikes to a peak (around 100 mm/year) due to adolescent hormonal changes. Adolescence to Adulthood (14–20 years): Plummets toward zero as bones fuse and final adult height is reached.
• 64.
  SUMMARY:- • Growth assessmentis an essential part of child health care. • Anthropometric measurements provide valuable information about physical growth and nutritional status. • WHO Growth Standards are recommended for children below 5 years, while IAP Growth Charts are used for children and adolescents 5–18 years. • Regular growth monitoring allows early detection of nutritional deficiencies and growth disorders. • Timely intervention promotes healthy growth and overall development. • Growth assessment and developmental assessment should always be performed together. While anthropometric measurements evaluate physical growth, the Denver Developmental Screening Test assesses developmental milestones, ensuring a comprehensive evaluation of child health.
