Health-body mass index body mass index

Clinicians and researchers often use body mass index (BMI), that is, weight kg divided by the square of height m, to evaluate whether a person's weight is normal.

Body mass index = weight (kg)/ height (m? ), please refer to the table below:

The comparison between body mass index and ideal weight shows that body mass index is highly correlated with body fat and some diseases.

The importance of body mass index lies in the curve relationship between body mass index and all-cause mortality. With the increase of body mass index curve, the risks of cardiovascular complications (including hypertension and stroke), certain cancers, diabetes, gallstones, osteoarthritis and kidney diseases also increase.

The limitation of body mass index is that it can not evaluate the body composition and body fat distribution related to obesity types. The increase of bone and muscle weight, even the increase of plasma caused by fitness exercise, may affect the calculation result of body mass index. Due to long-term training or heredity, some people have more muscle weight than fat weight, but their higher body mass index may be misinterpreted. Such as weightlifters and wrestlers, are wrongly classified as overweight or obese.

The above is a brief introduction to the body mass index. If you need to know more about fitness, please pay attention.
