Body mass index (BMI) is a common standard to measure obesity. The calculation method is weight (kg) divided by the square of height (m). For example, the weight is 70kg, the height 1.7m and the body mass index = 70 ÷ (1.7× 1.7) = 24.
The results show that when the body mass index is 30 or above, the risk of death from cancer, heart disease, respiratory diseases, kidney disease and diabetes will increase. But too low body mass index is not good, and it is also related to the increased risk of death from various diseases.
Extended data
Body mass index measurement became popular in 1970, but it may not be suitable for everyone, such as some boxers and rugby players, whose muscle ratio is much higher than fat.
Athletes' muscle density is higher than fat, so they are heavier than fat. Therefore, their body mass index may exceed the standard, but in fact they are healthy. Of course, this kind of people only account for a very small number of the population, about 1%.
With the increase of age, the muscle proportion of athletes will decrease, and there may be a lot of visceral fat, especially for some smokers.
In addition, the body mass index is not suitable for pregnant women.
The distribution position of fat in human body is very important, which cannot be measured by body mass index. Therefore, it is best to combine body mass index and other readings, such as blood pressure, cholesterol and family history, to judge a person's risk of diabetes or heart disease.
