Weight-related quality of life was assessed with IWQOL scores. Analyses were adjusted for age at surgery, BMI, depressive symptoms (indicated by a score ≥17 on the Beck Depression Inventory–II), sex, race, and physical functional status (a score of 0 on the Health Assessment Questionnaire Disability Index indicates normal physical functional status; a score >0 indicates impaired physical functional status). Age at surgery was not retained in the final model for IWQOL total score or physical comfort score; sex and race were not retained in the final model for IWQOL physical comfort score; and BMI was not retained in the final model for IWQOL total score.
