Height < 165cm: height (cm)- 105 (male)
Height (cm)-100 (female)
② northerners = (height cm- 150)×0.6+50.
Southerners = (height cm- 150)×0.6+48.
Normal weight: = SW SW× 0. 10
Overweight: = SW+SW× (0.11~ 0.20)
Mild: = SW+SW× (0.2 1 ~ 0.30)
Moderate obesity: = SW+SW× (0.3 1 ~ 0.30)
Severity: = SW+SW× (0.3 1 ~ 0.50)
Thin: = SW-SW× (0.11~ 0.20)
Severe emaciation: =SW-SW×0.20 (and above 0.2 1)
Although China people belong to Asian race, the upper limit of the normal range of body mass index should be lower than the Asian standard, and they should be treated differently when judging whether they are obese by body mass index. Because China people's obesity has two characteristics: small body, small index, big belly and great harm.
Small size determines that the normal upper limit of body mass index is low. According to a survey of China people, the average blood pressure, blood sugar and triglyceride levels of China people with a body mass index greater than 22.6 are higher than those with a body mass index less than 22.6, but the level of high-density lipoprotein cholesterol beneficial to human body is lower. Therefore, experts believe that the upper limit of China people's normal body mass index should not be greater than 22.6, but lower than 24.9 in Europe and America and 22.9 in Asia.
Some experts suggest that the best value of China people's body mass index should be 20-22, with a body mass index greater than 22.6 as overweight and a body mass index greater than 30 as obesity.
The large proportion of abdominal obesity is the characteristic and potential danger of obesity in China. The proportion of China people whose body mass index exceeds 25 is obviously smaller than that of Europe and America, but the proportion of abdominal obesity is larger than that of Europe and America. In the first study, people with normal or not very high body mass index, if the abdominal circumference of men is greater than 10 1 cm and that of women is greater than 89 cm, or the ratio of waist circumference to hip circumference is greater than 0.9 for men and 0.85 for women, are as harmful as people with high body mass index.
