AbstractThe aims of the present study were to examine changes in health-related quality of life (HRQOL) and depressive symptoms in adolescents with extreme obesity undergoing Roux-en-Y gastric bypass (RYGBP) across the first postoperative year. A prospective longitudinal observational study of 31 adolescent patients undergoing RYGBP at a pediatric medical center (mean = 16.4 years; 64.5% females, mean BMI 63.5; 97% of study eligible and consecutive patients) was conducted. Participants completed two adolescent HRQOL measures, the PedsQL (generic) and the IWQOL-Kids (weight-related), the Beck Depression Inventory (BDI), and height and weight were measured at three time points: baseline, and 6 and 12 months following RYGBP. Prior to RYGBP, significant impairments in HRQOL were documented and 38.7% reported depressive symptomatology in the clinical range. As expected, BMI and depressive symptoms decreased and HRQOL improved from baseline to 12 months post-RYGBP. Linear mixed modeling analyses detected several nonlinear slopes in BMI, depressive symptoms, and the majority of HRQOL domains over time with deceleration in these postoperative changes beginning at the 6th month time point. In contrast, the rate of change in weight-related social relations was linear (e.g., no deceleration), indicating continued improvement across the first postoperative year. Adolescent RYGBP results in significant improvement in HRQOL and depressive symptomatology over the first postoperative year. Longer-term follow-up will be critical to determine adolescent weight and psychosocial trajectories, their interrelations, and what role psychosocial status plays in continued weight loss, maintenance, and regain.
