1
Physical development of children. Anthropometry Topic 5-6
2
Physical DEVELOPMENT: Neuropsychological biological
3
Stages: The measurement of anthropometric data The estimation of physical development
4
Methods of anthropometry
5
І. Адекватне обчислення віку дата обстеження – дата народження Закруглення віку до повного місяця або року ± 0,5 року або місяця
6
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.
7
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.
8
Physical growth estimation
9
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.
10
Physical growth estimation
11
Empirical formulas for: Length Height Body mass Circumferences
12
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)
13
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 –at 12 mnts : W birth * 3
14
- Bounds - 7-10% - Rough estimate of body dimensions - For prompt use
16
Methods of anthropometric stadards: -Accuracy -Reliability -Objectivity Types of anthropometric stadards: -Parametric (sigmal, regression) -Nonparametric (percentile)
17
± 1 σ ± 2 σ ± 3 σ Mean
18
1 % 50 % 100 %
19
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
24
Anthropometric indexes
25
Height (in cm) – body mass (in kg) =100 Index Brauquas Body mass index - BMI BMІ = W / H 2 (kg/m 2 ).
26
Body mass deficiency Body mass excess
27
Hypotrophy, leanness I degree < 11 – 20 % II degree < 21 – 30 % III degree < 30 %
28
Obesity І degree: > 10-29% ІІ degree : > 30-49% ІІІ degree : > 50-100% IV degree : > 100%
