Changes in Marital Status Following Roux-en-Y Gastric Bypass and Sleeve Gastrectomy: A US Multicenter Prospective Cohort Study

Among a US cohort followed 5 years after Roux-en-Y gastric bypass or sleeve gastrectomy, cumulative incidence of marriage and separation/divorce were 18% among unmarried (N=614) and 13% among married (N=827) participants, respectively. Preoperative predictors of marriage included younger age, college degree, lower BMI and cohabitating or being separated (versus single). OBJECTIVES: To describe changes in marital status following Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). BACKGROUND: Spousal encouragement and finding a life partner are self-reported motivators for undergoing bariatric surgery. METHODS: This study included 1441 US adults enrolled in a 6-center prospective cohort study who underwent RYGB or SG (2006–2009) and self-reported marital status preoperatively and annually postoperatively for ≤5 years. Time to change in marital status was analyzed with Kaplan–Meier estimates of cumulative incidence and Cox proportional-hazard models. RESULTS: Preoperative, 57% of participants (79% female, median age 47 years, median body mass index [BMI] 47 kg/m(2)) were married, 5% cohabitating, 4% separated, 15% divorced, 2% widowed, and 17% always single. The 5-year cumulative incidence of marriage among unmarried participants (N = 614) was 18%. Cohabitating (hazard ratios [HR] = 5.25) or being separated (HR = 3.03) versus always single, younger age (HR = 1.69/10 years), having a college degree versus ≤high school (HR = 2.36), lower BMI (HR = 1.54/10kg/m(2)), and fewer depressive symptoms (HR = 1.47/10 Beck Depression Inventory points) preoperative independently predicted (P < 0.05) higher chance of marriage. The 5-year cumulative incidence of separation/divorce among married participants (N = 827) was 13%. Female sex (HR = 2.08), younger age (HR = 1.84/10 years), household income <$25,000 versus ≥$100,000 (HR = 2.48), smoking (HR = 1.76), and sexual desire ≥once/week versus never (HR = 2.12) preoperative independently predicted (P ≤ 0.05) separation/divorce. CONCLUSIONS: Among a cohort of US adults, the majority did not change marital status within 5 years following RYGB or SG. Cumulative incidence of marriage and separation/divorce was 18% among unmarried and 13% among married participants, respectively. Several preoperative predictors of marriage and separation/divorce were identified.
