Abstract
BackgroundAmong adolescents who underwent metabolic and bariatric surgery (MBS), it is unclear how relationships and specifically marital status (MS) may be associated with long-term weight loss. ObjectiveIn this analysis, we tested for associations between the MS of adolescents who underwent MBS and the MS of their primary caregiver and weight loss trajectory over 8 years. SettingTeen-LABS participating sites. MethodsThis sample included 231 participants (75.3% female, 71.4% White, 68.0% Roux-en-Y gastric bypass, 27.7% vertical sleeve gastrectomy, 4.3% laparoscopic adjustable gastric band). A linear mixed model was conducted with the dependent variable percent body mass index (BMI) change from preoperatively through 8 years with between-participant factors (1) participant MS, (2) caregiver MS, and (3) interaction between caregiver and participant MS. ResultsOne third of participants and 87% of caregivers were ever married (EM). Compared with never-married (NM) participants and caregivers (–14.6%), EM participants and caregivers (–20.6%), EM participants and NM caregivers (–25.9%), and NM participants and EM caregivers (–19.8%), each had significantly greater BMI loss at 8 years (each P < .05). No other group comparisons achieved statistical significance. ConclusionsNM participants with NM caregivers had less favorable long-term BMI. Additional research is needed to better understand how relationships affect behavior change and weight loss after MBS.
