Background: Comprehensive studies of adolescent bariatric surgery outcomes are in their infancy and are critically needed. The present study examined the rate of change in the body mass index (BMI), health-related quality of life (HRQOL), depressive symptoms, and self-concept in adolescents undergoing Roux-en-Y gastric bypass (RYGB) during the first 24 postoperative months using a prospective longitudinal design at a pediatric medical center. Methods: A total of 16 adolescents (mean age 16.2 yr; 62.5% female, mean BMI 59.9 kg/m 2; 97% of eligible, consecutive patients) completed the Impact of Weight on Quality of Life-Kids, Pediatric Quality of Life Inventory, Beck Depression Inventory, Self-Perception Profile for Adolescents, and height and weight measurements at baseline and 6, 12, 18, and 24 months after RYGB. A total of 75% participated at all follow-up points. Results: Before RYGB, global psychosocial impairments were documented. Hierarchical linear modeling was used to examine the growth trajectories. Several quadratic (nonlinear) trends were revealed. A substantial reduction in weight and depressive symptoms, as well as improved HRQOL and self-concept were identified across the first postoperative year, followed by decelerations in year 2, including weight regain (P <.0001) and slight increases in depressive symptoms (P =.004) and decreases in HRQOL (Social, P =.002; Body Esteem, P =.0007; Physical Comfort, P <.0001; and Total, P <.0001), and self-concept (Social, P =.02; Appearance, P =.002; and Close Friendship, P =.008). Conclusion: During the first 24 months after RYGB, preliminary evidence suggests adolescents experience significant weight loss as well as psychosocial and HRQOL improvements. A deceleration in these gains occurred in the second postoperative year. Longer term follow-up with larger samples is critical to determine the weight and psychosocial trajectories, and what role psychosocial status plays in adolescents' weight change and maintenance.
