Body-mass index (BMI) is a simple and commonly used measurement in clinical medicine and population health—a ratio of weight (kilogrammes) and height (metres squared). Adults with a BMI of 25–29·9 kg/m2 are considered overweight and adults with a BMI of 30 kg/m2 or higher are considered obese. The causes and consequences of overweight and obesity, however, are anything but simple. Determinants of BMI include genetic and epigenetic factors; individual behaviours (eg, physical activity, sedentary time, and caloric intake); sociocultural factors; and the physical, economic, and policy environments.
