Extended data:
First, the standard weight calculation method:
1, standard weight calculation method (7- 16 years old)
Standard weight (kg) = age x 2+8 (7-16 years old)
Mild obesity: 20%-30% over standard weight.
Moderate obesity: 40%-50% over standard weight.
Severe obesity: more than 50% of the standard weight.
2. BMI method
Body mass index BMI = weight (kg)/height (m) squared, that is, kg/m2 age BMI value.
Second, the height calculation formula
Prediction of adult height by children's body length
1, male height = birth length (cm) ÷ 0.2949;
Female height = length at birth (cm) ÷0.3 109.
It should be noted that this formula is only applicable to normal full-term newborns; If the data of body length can be measured accurately to 0. 1 cm, the prediction of height will be more accurate.
2. Male height =3 years old, height ×0.545+ average height of parents ×0.544+37.69 (cm);
Height of female =3 years old ×0.545+ average height of parents ×0.544+25.63 (cm), and prediction formula of human standard height (genetic law).
