title: Disorders of childhood growth and development: childhood obesity.
abstract: The incidence of childhood obesity in the United States is estimated at 17%, or 12 million children ages 2 to 19 years. Obesity is a multifactorial condition with syndromic and nonsyndromic variants. Genetic, social, ethnic, endocrinologic, and behavioral issues are all potential etiologic factors. Preventive efforts should begin with monitoring from birth and include breastfeeding until age 6 months, avoiding juices, and promoting fruit and vegetable consumption and adequate exercise. Childhood obesity is diagnosed based on body mass index; a child is considered overweight at the 85th to 95th percentiles and obese at or above the 95th percentile. After obesity is diagnosed, testing should include blood pressure levels, fasting lipid profile, diabetes screening, and liver function tests. The physician should obtain a detailed history of the physical activity level and food intake and assess possible complications of obesity, including depression and hypertension, annually. Lifestyle interventions with family involvement are the mainstay of management, with pharmacotherapy or bariatric surgery considered for adolescents only if intensive lifestyle modifications have failed and in the presence of comorbidities. Intervention by multiple disciplines (ie, medicine, nutrition, psychology) is recommended, and family physicians are encouraged to become more involved in encouraging physical activity and improved nutrition for children.
