The formula for calculating body mass index (BMI) is BMI = weight/height 2.
First, the body mass index noun explanation
Body mass index (BMI) is a commonly used index to evaluate a person's weight.
The calculation results of body mass index can be used to evaluate a person's weight status and be explained with reference to the internationally accepted classification standards of body mass index. Body mass index < 18.5: light; 18.5 ≤ body mass index < 24.9: normal weight range; 25.0 ≤ body mass index < 29.9: overweight; Body mass index ≥30.0: obesity.
Second, the calculation steps
1. The unit of weight is kilograms (kg).
2. Measure the height in meters (m).
3. The square of height (that is, height × height).
4. Divide weight by the square of height to get the value of body mass index.
Some potential hazards of abnormal body index;
1, health risks increase.
Too low or too high body mass index is associated with many health problems and increased risk of chronic diseases. For example, low body mass index may lead to malnutrition, immune system damage, osteoporosis and other problems, while high body mass index is related to the increased risk of cardiovascular diseases, hypertension, diabetes, fatty liver and other diseases.
2. Cardiovascular health problems
Overweight and obesity are associated with increased risk of cardiovascular diseases, such as hypertension, coronary heart disease and stroke. Excessive body mass index may lead to arteriosclerosis, dyslipidemia and the development of heart disease.
3. Metabolic disorders
Obese or overweight people are often accompanied by metabolic disorders, such as insulin resistance and lipid metabolism disorders, which increase the risk of diabetes and metabolic syndrome. However, people with low body mass index often have metabolic problems, which are prone to hypoglycemia and fainting, causing serious health hazards.
4. Bone problems
Low body mass index may lead to an increased risk of osteoporosis and fracture. Low body weight may indicate insufficient supply of calcium and other minerals in bones, which increases the risk of osteoporosis.
