Body mass index (BMI)
Body mass index (BMI) is a number obtained by dividing the weight in kilograms by the square of the height in meters, which is mainly used for statistics.
When it is necessary to compare and analyze the influence of a person's weight on the health of people with different heights, the body mass index value is a neutral and reliable indicator.
Body mass index was originally designed as a statistical tool for public health research. With the development of science and technology, the current body mass index value is only a reference value.
