1, WHO calculation method
The standard weight of men is equal to (height-80) × 70%;
The standard weight of women is equal to (height-70) × 60%;
Normal weight is plus or minus10% of standard weight;
Overweight or underweight is+10 ~ 20% of the standard weight;
Obesity or underweight exceeds 20% of the standard weight;
The overweight coefficient is equal to (actual weight-ideal weight)/(ideal weight).
2. Different age algorithms
The standard weight is equal to the age x 8+8 (only applicable to 7- 16 years old);
Mild obesity exceeds the standard weight by 20%-30%;
Moderate obesity exceeds the standard weight by 30%-50%;
Severe obesity exceeds the standard weight by more than 50%.
Extended data
Measurement method of obesity
1, weighing
Men's standard weight: height minus105; Female standard weight: height minus 100. Normal body weight is within the standard plus or minus 10%, and obesity is above 10%.
2. Body mass index
The weight in kilograms divided by the height in square meters. This method is more accurate and is used by the state to measure overweight and obesity. The normal range is 18.5-23.9, 24-27.9 overweight, and obese over 28. For children, the diagnostic standard is different from that of adults, which is a little lower.
