Physical growth estimation

Physical growth estimation

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 : ,5 х (а-6)

Infant weight Birth to 6 months: W = W birth * а (g) –3-12 months: W = (9 + а)/2 (kg), –where “а” age in months Other method - –at 6 mnts: W birth * 2 –at 12 mnts : W birth * 3

Methods of anthropometric stadards: -Accuracy -Reliability -Objectivity Types of anthropometric stadards: -Parametric (sigmal, regression) -Nonparametric (percentile)

± 1 σ ± 2 σ ± 3 σ Mean

1 % 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

Anthropometric indexes

Height (in cm) – body mass (in kg) =100 Index Brauquas Body mass index - BMI BMІ = W / H 2 (kg/m 2 ).

Body mass deficiency Body mass excess

Hypotrophy, leanness I degree < 11 – 20 % II degree < 21 – 30 % III degree < 30 %

Obesity І degree: > 10-29% ІІ degree : > 30-49% ІІІ degree : > % IV degree : > 100%
