BACKGROUND: Prior studies have reported that students with overweight and obesity have impairments in performance IQ and executive function and worse school functioning in comparison with peers of normal weight. The present study assessed school and cognitive functioning in a sample of adolescents with severe obesity being evaluated for laparoscopic adjustable gastric banding. METHODS: Eligible candidates for bariatric surgery were referred for psychiatric evaluation, which included a semistructured clinical interview measuring school functioning and the vocabulary and matrix reasoning subtests of the Wechsler Abbreviated Scale of Intelligence (WASI). RESULTS: Self-reported school problems were common, with 55.5% of adolescents failing a grade or subject, 38.7% attending summer school, and 17.8% failing a citywide examination. A significant relationship was observed between body mass index, estimated WASI IQ (r = -.250; P = .005), and the vocabulary subtest (r = -.241; P = .006), but not matrix reasoning (r = -.126; P = NS). CONCLUSION: Even among a sample of adolescents with severe obesity, increased body mass index was associated with lower WASI IQ and vocabulary subtest scores. Increasing awareness of potential cognitive and school problems in bariatric candidates among teachers, school counselors, and other mental health providers is an important first step to improving academic support and educational systems deficiencies for students with overweight and obesity.
