# BODY MASS INDEX (BMI)

Introduction
Body Mass Index (BMI) is a measure of body size that is used to assess a person’s body composition. It is calculated by dividing a person’s weight in kilograms by the square of his or her height in meters. The resulting number is then compared with a standard set of ranges to determine whether or not a person is considered to be underweight, healthy weight, overweight, or obese. BMI is an important tool for understanding the health risks associated with being overweight or obese and can be used to help design interventions to prevent or control these conditions.

Body composition
The amount of body fat a person has is an important determinant of their health. Excess body fat is associated with an increased risk of a number of chronic conditions, such as type 2 diabetes, hypertension, and coronary heart disease. BMI is a useful tool for assessing a person’s body composition and can be used to estimate the amount of body fat present in an individual.

Calculation
BMI is calculated by dividing a person’s weight in kilograms by the square of his or her height in meters. To determine a person’s BMI, the following equation should be used:

BMI = weight (kg) / height2 (m2)

Interpretation
Once a person’s BMI has been calculated, it can be compared with a standard set of ranges to determine whether or not a person is considered to be underweight, healthy weight, overweight, or obese. Generally, a BMI of 18.5 to 24.9 is considered to be a healthy weight, a BMI of 25 to 29.9 is considered to be overweight, and a BMI of 30 or greater is considered to be obese.

Conclusion
BMI is a useful tool for assessing body composition and can be used to estimate the amount of body fat present in an individual. It is an important tool for understanding the health risks associated with being overweight or obese and can be used to help design interventions to prevent or control these conditions.
