Overweight and obesity is one of the key risk factors for many noncommunicable diseases (NCD) such as coronary heart disease, hypertension, and stroke, certain types of cancer, type 2 diabetes, gallbladder disease, dyslipidemia, osteoarthritis and gout, and pulmonary diseases. Body mass index (BMI) is a surrogate marker of adiposity calculated by dividing the weight of a person in kilograms by the square of the height in meters (kg/m²). In the case of adults, a person with a BMI equal to or greater than 30 is considered obese and a BMI equal to or greater than 25 is considered overweight. The BMI categories for defining obesity vary by age and gender in infants, children and adolescents.
