Body Mass Index (BMI) is a widely used measure of body weight relative to height that is used to classify individuals as underweight, normal weight, overweight, or obese. It is calculated by dividing an individual's weight in kilograms by their height in meters squared. BMI is commonly used as a screening tool to identify individuals who may be at risk for obesity-related health problems. While it is a useful tool for assessing body weight and potential health risks, BMI does have limitations, such as not taking into account other factors like muscle mass or distribution of body fat. Research in the area of BMI often focuses on its association with various health outcomes, such as cardiovascular disease, diabetes, and mortality. Studies may explore the relationship between BMI and these health outcomes, as well as potential interventions to help individuals maintain a healthy weight.
