1. The Body Mass Index (BMI) is calculated by dividing a person's weight in kilograms by the square of their height in meters.
2. This formula provides a commonly used measure of a person's body fatness and overall health status.
3. A BMI within the range of 18.5 to 23.9 is considered normal.
4. The BMI scale is applicable to adults aged 18 to 65 years, but it is not suitable for children, adolescents, pregnant women, lactating mothers, the elderly, or individuals with significant muscle mass.
5. According to American medical statistics, individuals with a BMI less than 16 and those with a BMI greater than 30 have the highest mortality rates.
6. The lowest mortality rates are found in individuals with a BMI between 20 and 22.
7. Some theories suggest that the ideal BMI values for women and men are 19 and 22, respectively.
8. Based on these ideal BMI values, the ideal body weight can be estimated as follows:
- Ideal body weight for women = 19 x height x height
- Ideal body weight for men = 22 x height x height
9. BMI is a tool for assessing the weight-to-height ratio, but it does not reflect the body's fat content.
10. In fact, excessive fat content is the key factor posing a threat to health, rather than the BMI number alone.详情
