Cross-Sectional Standard Growth Chart Height(cm) boy average Height Weight(Kg) average Weight AGE(year) 5 Data

Cross-Sectional Standard Growth Chart Height(cm) boy average Height Weight(Kg) average Weight AGE(year) 5 Data in 2000

● Rohrer Index =weight (kg)/( height (cm)3)x 107 ● Rohrer index =weight (kg)/( height

● Rohrer Index =weight (kg)/( height (cm)3)x 107 ● Rohrer index =weight (kg)/( height (m)3)x 10 Rohrer index Useful to calculate for obesity level of children 6

● Rohrer index ex. height : 135 cm, weight : 30 kg 3 Rohrer

● Rohrer index ex. height : 135 cm, weight : 30 kg 3 Rohrer index = 30÷ 1. 35 × 10 = 30/2. 46× 10 = 122(Normal Weight) 7

● Rohrer Index Severe Underweight under 100 Underweight 100<115 Normal Weight 115<145 Overweight 145<159

● Rohrer Index Severe Underweight under 100 Underweight 100<115 Normal Weight 115<145 Overweight 145<159 Obese over 160 8

● Kaup Index (BMI) = ( weight (g)/ height (cm)2)x 10 ● Kaup index

● Kaup Index (BMI) = ( weight (g)/ height (cm)2)x 10 ● Kaup index (BMI) =weight (g)/ height (cm)x 10 Kaup index (BMI) Useful to calculate for obesity level of small children and adult 9

● Kaup index ex. height : 100 cm Kaup index (1 m), weight :

● Kaup index ex. height : 100 cm Kaup index (1 m), weight : 20 kg = 20000÷ 1002× 10 = 20000/10000× 10 = 20(Normal Weight) BMI = 20÷ 12 = 20/1 = 20(Normal Weight) 10

● Kaup index (for small children) Severe Underweight < 13 Underweight 13 <15 Normal Weight

● Kaup index (for small children) Severe Underweight < 13 Underweight 13 <15 Normal Weight 15  < 18 Overweight 18 < 20 Obese 20 < 11

●BMI (for adult) Underweight < 18. 5 Normal Weight 18. 5 < 25 Overweight

●BMI (for adult) Underweight < 18. 5 Normal Weight 18. 5 < 25 Overweight 25 < 30 Obese 30 < 12
