Standard weight (kg):

① Height 4102 > 165cm: height (cm)-100

Height < 165cm: height (cm)- 105 (male)

Height (cm)-100 (female)

② northerners = (height1653cm-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)

Male standard weight (kg) = body length (cm)- 100.

Female standard weight (kg) = length (cm)-102

First, the world obesity standard

At present, body mass index (BMI) is used all over the world to measure whether a person is obese or not. The calculation method is: body mass index = weight (kg) divided by the square of height (m).

The world standard drawn up by large organizations in the world is that the body mass index is within the normal range of 18.5-24.9, with a body mass index greater than 25 as overweight and an MBI greater than 30 as obesity.

However, experts attending the meeting pointed out that this weight standard is based on white people in Europe and America and may not be applicable to Asians.

Second, Asian obesity standards

Asians are too young to be measured by the world's "normal range" weight standard BMI 18.5-24.9. For example, when my body mass index was 24.9 on that day, my risk of hypertension increased by three times; Among Japanese in the United States, when the body mass index is greater than 23, the risk of cardiovascular disease begins to increase significantly; In China, the mortality rate of body mass index is the lowest, at 23.7, and it starts to rise when it is higher. This shows that the world standard of the normal upper limit of body mass index of 24.9 is obviously too high for Asians.

So, what should the Asian obesity standard be? Experts believe that the body mass index is normal at 18.5-22.9, overweight at 23 and obese at 30. In this way, the upper limit of the normal body mass index of Asians is two indicators lower than that of Europeans and Americans, and the difference is not too big.

Third, China obesity standards

Chinese experts believe that 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 with 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.
