Body mass index is standard weight (kg) = height (cm)-105. The actual weight is normal within 10% of the standard weight calculated according to the formula, over 20% is obese, 20%-30% is mildly obese, 30%-50% is moderately obese, and over 50% is severely obese.

For example, a girl is 1.6m in height and 50kg in weight. The standard weight is:

1, body mass index (BMI) = 50/1.62 = 50/2.56 =19.53.

2. The body mass index is the standard weight (kg) = 160- 105=55.

The range of body mass index (BMI) of male college students is 17.9-23.9.

The body mass index (BMI) of female college students ranges from17.2 to 23.9.

Extended data:

Body Mass Index (in English) is a number obtained by dividing the weight in kilograms by the square of the height in meters, and it is a commonly used international standard to measure the degree of obesity and health. When we need to compare and analyze the influence of a person's weight on the health of people of different heights, the body mass index is a neutral and reliable indicator.
