Change, predictors and correlates of weight- and health-related quality of life in adolescents 2-years following bariatric surgery


Weight-related quality of life (WRQOL) and generic health-related quality of life (HRQOL) have been identified as important patient-reported outcomes for obesity treatment and outcome research. This study evaluated patterns of WRQOL and HRQOL outcomes for adolescents at 24-months post-bariatric surgery relative to a nonsurgical comparator sample of youth with severe obesity, and examined potential weight-based (e.g., BMI, weight dissatisfaction) and psychosocial predictors and correlates of these outcomes.


Multi-site data from 139 adolescents undergoing bariatric surgery (Mage = 16.9; 79.9% female, 66.2% White; MBody Mass Index [BMI] = 51.5 kg/m2) and 83 comparators (Mage = 16.1; 81.9 % female, 54.2% White; MBMI = 46.9 kg/m2) were collected at pre-surgery/baseline, 6-, 12-, and 24-months post-surgery/baseline with high participation rates across time points (>85%). Self-reports with standardized measures of WRQOL/HRQOL as well as predictors/covariates (e.g., weight dissatisfaction, social support, peer victimization, family dysfunction, loss of control eating, self-worth, and internalizing symptoms) were obtained. Growth curve models using structural equation modeling examined WRQOL/HRQOL over time and linear regressions examined predictors and correlates of WRQOL/HRQOL outcomes.
