Sleeve gastrectomy for youth with cognitive impairment or developmental disability

Abstract

BACKGROUND AND OBJECTIVES: Youth with cognitive impairment or developmental disability (CI/DD) face higher rates of obesity and secondary medical issues. Bariatric surgery may be a helpful tool for health improvement because it has been shown efficacious for adolescents. We aim to contribute to literature regarding bariatric surgery for adolescents with CI/DD and explore the association between cognitive functioning and weight loss outcomes. METHODS: Adolescents (N = 64) received a preoperative psychological evaluation, including cognitive assessment, and bariatric surgery at 1 weight loss program between 2010 and 2017. For these adolescents with measured cognitive performance, CI/DD was defined by an IQ,80 or previous diagnosis. In analyses, we compared adolescents with and without CI/DD. Structural equation modeling was used to assess the impact of cognitive functioning on weight loss 3 to 24 months postsurgery. RESULTS: There were no significant differences between adolescents with or without CI/DD in terms of preoperative BMI, age, and sex. Having CI/DD did not significantly impact weight loss or weight loss trajectory in the 2 years after surgery, although modeling revealed a trend toward individuals with CI/DD losing more weight over time. Similarly, intelligence scores did not predict weight loss after surgery. CONCLUSIONS: Bariatric surgery may be a helpful tool for adolescents with severe obesity and CI/DD. They could benefit from the surgery as much as those with typical development, and having CI/DD should not be used as a criterion to deny surgery. Continuing research with this population can be used to determine long-term outcomes in addition to defining best practices.
