Body mass index (BMI)

It is an important standard commonly used in the world to measure the degree of human obesity and whether it is healthy, and is mainly used for statistical analysis. The absolute value of weight can't be used to judge the degree of obesity, and the degree of obesity is naturally related to height. Therefore, the body mass index (BMI) obtains a relatively objective parameter through the two values of human body weight and height, and measures the physical quality by the range of this parameter.

Body mass index Body mass index = weight/height squared (international unit kg/㎡)

Ideal weight (kg) = (18.5 ~ 23.9) × the square of height (unit m)

According to the standards set by the World Health Organization, Asians are overweight if their BMI exceeds 22.9.

Body mass index application scope:

According to domestic standards, the body mass index less than 18.5 belongs to the normal range, and the body mass index of 18.5-24, 24-28 belongs to the obese group. Because the body mass index is only calculated by height and weight, it is not suitable for pregnant women, young children and the elderly, as well as professional fitness athletes.

Body mass index (BMI) cannot be used as the only criterion to judge whether a person is fat or thin. The body mass index (BMI) may be the same due to different body fat percentages.
