Obesity is defined in terms of Body Mass Index (BMI), which is a person's weight in kilograms divided by the square of height in meters. A adult with a BMI from 18.5 to 24.9 is considered to have a normal or healthy weight. Below 18.5 is considered underweight, from 25 to 29.9 is overweight and 30 and over is obese. Although BMI is an indirect measure of body fat and should be used for screening rather than diagnosis at the individual level, studies have shown that BMI correlates with body fat and future health risks and is therefore a reliable measure of the prevalence of overweight and obesity in a population.
