In adults, obesity is defined as a body mass index (kg/m2) of 30 or higher and overweight is defined as a BMI between 25.0 and 29.9. In children and adolescents, obesity is defined as a BMI at or above the 95th percentile for age and gender, and overweight is defined as a BMI at or above the 85th percentile. Current estimates suggest that 32% of men and 35% of women in the USA meet criteria for obesity (Flegal, Carroll, Ogden, & Curtin, 2010).
