Stages: The measurement of anthropometric data The estimation of physical development
І. Адекватне обчислення віку • дата обстеження – дата народження • Закруглення віку до повного місяця або року • ± 0,5 року або місяця
Weight, body mass. • Index of physical growth; • Index of quality of nutrition; • Sign of some diseases; • Symptom of dehydratation; • Symptom of excessive hydratation, fluid retention.

Weight, body mass. • Index of physical growth; • Index of quality of nutrition; • Sign of some diseases; • Symptom of dehydratation; • Symptom of excessive hydratation, fluid retention.
Physical growth estimation Methods of empirical formulas
Empirical formulas for: • Length • Height • Body mass • Circumferences
Infant body length • Birth to 6 months: L = L birth + 3 * а (cm) • 7-12 months: L = 64 + а, • where “а” age in months • Other method - • Before 6 mnts:66 – 2,5 х (6-а) (cm) • After 6 mnts: 66 + 1,5 х (а-6)
Infant weight • Birth to 6 months: W = W birth + 800* а (g) • 3-12 months: W = (9 + а)/2 (kg), • where “а” age in months • Other method - • at 6 mnts:W birth * 2 • at12mnts: W birth* 3
Methods of empirical formulas • Bounds - 7-10% • Rough estimate of • body dimensions • For prompt use
Methods of anthropometric standards
Methods of anthropometric stadards: • Accuracy • Reliability • Objectivity Types of anthropometric stadards: • Parametric (sigmal, regression) • Nonparametric (percentile)
± 1 σ Sigmal - parametric ± 2 σ Mean ± 3 σ
1 % Percentile - nonparametric 50 % 100 %
Centum = 100 All anthropometric data of special children group (separated by age and gender) are divided for 100 intervals. 2 types – percentile tables percentile charts
Body mass space percentile Age
pathological normal pathological
Anthropometric indexes
Index Brauquas Height (in cm) – body mass (in kg) =100 Body mass index - BMI • BMІ = W / H2 (kg/m2).
Body mass excess Body mass deficiency
Hypotrophy, leanness • Idegree <11 – 20 % • IIdegree <21 – 30 % • IIIdegree < 30 %
Obesity І degree:> 10-29% ІІ degree :> 30-49% ІІІ degree :> 50-100% IVdegree :> 100%
