What is the body mass index?

Body mass index (BMI) is a standard to measure obesity and health. Body mass index (BMI), also known as weight or BMI, is a number obtained by dividing the kilograms of weight by the square of the meters of height. It is a widely used international standard to measure the degree of obesity and health.

For different races, the same body mass index may represent different degrees of obesity. The level of body mass index in Asia (including China) is lower than that in European countries as a whole, but according to many studies, Asians are already at high risk of cardiovascular diseases at a low level of body mass index.

Body mass index greater than or equal to 24 is overweight, and greater than or equal to 28 is obese; Male waist circumference is greater than or equal to 85 cm, and female waist circumference is greater than or equal to 80 cm. If there is no specific standard to judge people's nutritional status, we can only use some relatively vague words such as "normal", "good", "obesity" and "emaciation" to describe it.

Influencing factors of physique:

Physical fitness is inherited and acquired, and the inherent and relatively stable characteristics of human individuals in morphological structure and functional activities are related to their psychological character.

The difference of individual constitution is manifested in some differences in response and adaptation to external stimuli under physiological conditions, as well as susceptibility to certain pathogenic factors and tendency of disease development during the onset.
