202 1 standard weight and height comparison table

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 formulated by the World Health Organization, Asians are overweight if their body mass index (BMI) is higher than 22.9.

Asians and Europeans and Americans belong to different races, and the WHO standard is not suitable for the situation of China people, so the China reference standard was formulated.

Body mass index (BMI) is an important international standard to measure the degree of obesity and health status, which 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.

There is a new standard to measure obesity.

Body mass index (BMI) is a commonly used index to evaluate whether a person's weight is reasonable. However, after research, scientists at Cedes Sinai Medical Center in San Francisco, California, found a more scientific body fat characteristic index-Relative Fat Mass Index (RFM).

Experts all over the world admit that the body mass index is not perfect. It does not consider gender differences (women usually have more body fat than men); There is no difference in bone mass, muscle mass and excess fat, and the measurement results of children and the elderly may be quite different. It can be said that body mass index (BMI) has always been a rough index to investigate the problem of population obesity.

This time, based on the data of10.2 million adults in the Health and Nutrition Survey of the Centers for Disease Control and Prevention, the researchers worked out more than 300 formulas for estimating body fat, and finally got the RFM calculation method. The specific measurement method is as follows:

Measure your height and waist circumference, and then substitute the numbers into the following formula:

Male: 64-(20× height/waist circumference) =RFM.

Female: 76-(20× height/waist circumference) =RFM.

The normal range of adult body fat rate is 20%~25% for women and 15%~ 18% for men.

Researchers say that the relative fat mass index is a better indicator to measure the degree of obesity, which can not only reliably judge whether someone's body fat percentage is at a healthy level, but also be simple and cheap to measure. You don't need complicated equipment such as a scale, the only tool you need is a tape measure.
