Body mass index (BMI), referred to as body mass index, is a commonly used international standard to measure obesity and health. The formula is body mass index = weight/height.
Body mass index (BMI) is a commonly used index to measure obesity and health in the world. The normal body mass index is between 20 and 25. If it exceeds 25, it means overweight, and if it exceeds 30, it means obesity. It was first put forward by Belgian generalist kettler in the middle of19th century.
The following are the main application aspects:
1. Assessing obesity level: Body mass index is the main index to assess obesity level, and obesity level is generally divided according to the range of body mass index value. For example, the World Health Organization (WHO) classifies people into four grades according to the range of body mass index: thin, normal, overweight and obese.
2. Risk assessment: Body mass index is related to the occurrence and health status of certain diseases, such as cardiovascular diseases, type 2 diabetes and certain cancers. Some studies show that the higher the body mass index, the higher the incidence of related diseases, so it can be used to assess the risk of illness.
3. Applicability evaluation: According to the body mass index, the applicability of public facilities and some products can be evaluated. For example, obese people may not be able to wear ordinary-sized seats or vehicles.
4. Height and weight matching: Body mass index can be used to evaluate the matching degree of height and weight. If the body mass index value is too high or too low, it may indicate that the height-weight matching degree is unreasonable, such as being overweight or thin.
Body mass index (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.
Mainly used for statistical purposes, when we need to compare and analyze the health effects of a person's weight on people of different heights, the body mass index value is a neutral and reliable indicator.
