Bariatric surgery for adolescents

Stefater MA, Jenkins T, Inge TH. Bariatric surgery for adolescents Pediatric Diabetes 2013: 14: 1-12. Obesity is no longer just an adult disease. An increasing number of youth are overweight, defined as body mass index (BMI) at or greater than the 95th percentile for age (1). Between 2009 and 2010, 16.9% of children aged 2-19 yr were classified as overweight based on BMI (2), as compared with only 5% of children affected by obesity in 1976-1980 (3). This is a problem of enormous proportion from a public health standpoint, as without intervention these children will grow up to become overweight and obese adults. For an obese child, the risk of becoming an obese adult may be as high as 77%, compared with 7% for a child of healthy weight (4). Morbid obesity is a major risk factor for later complications such as cardiovascular disease, type 2 diabetes, obstructive sleep apnea (OSA), polycystic ovary syndrome (PCOS), and degenerative joint disease (4-10). Obesity is also an expensive problem: the US government spends $147 billion yearly on obesity-related healthcare costs (11). Thus, there is an urgent need to target obesity in the pediatric population, before the expensive and life-threatening consequences of obesity manifest. Unfortunately, the effectiveness of medical treatments for obesity is limited. Behaviorally based dietary and physical activity interventions offer little benefit for pediatric obesity, while pharmacologic therapy is also limited and carries low success rates and recidivism (12-14) (Table 1).
