Ideal weight (kg) = (18.5 ~ 23.9) × the square of height (unit m) According to the standards formulated by the World Health Organization, Asians are overweight if their body mass index (BMI) is higher than 22.9.
Asians and Europeans and Americans belong to different races, and the WHO standard is not suitable for the situation of China people, so the China reference standard was formulated.
Body mass index (BMI) is an important international standard to measure the degree of obesity and health status, which is mainly used for statistical analysis. The absolute value of weight can't be used to judge the degree of obesity, and the degree of obesity is naturally related to height. Therefore, the body mass index (BMI) obtains a relatively objective parameter through the two values of human body weight and height, and measures the physical quality by the range of this parameter.
1, WHO calculation method for standard weight
Male: (height cm-80)×70%= standard weight.
Female: (height cm-70)×60%= standard weight.
Standard weight plus or minus 10% is normal weight.
Standard weight plus or minus 10%~20% overweight or underweight.
More than 20% of the standard weight is obese or underweight.
Overweight calculation formula:
Overweight% = [(actual weight-ideal weight)/(ideal weight) ]× 100%.
2. Different age algorithm of standard weight
Standard weight method:
Mild obesity: 20%-30% overweight.
Moderate obesity: 30%-50% overweight.
Severe obesity: more than 50% of standard weight.
3, the standard weight body mass index method
Body mass index Body mass index = weight (kg)/height (m) squared.
