BACKGROUND: Though psychosocial factors are routinely examined in pre-surgical psychological evaluations, the predictive value of some psychosocial factors on post-surgical weight loss is still relatively unknown. Additional research examining the predictive value of psychological constructs pre-operatively and long-term weight outcomes is needed to enhance the clinical utility of the pre-surgical psychological evaluations. OBJECTIVES: This study aimed to examine psychosocial factors as predictors of weight outcomes 30 months after bariatric surgery. SETTING: University Hospital in the Appalachian region of United States. METHODS: Participants included 196 adults who underwent bariatric surgery. Psychosocial data were collected as part of a routine psychological evaluation prior to bariatric surgery. Objective weight was obtained through patients’ medical record at 12, 24, and 30 months after surgery. RESULTS: Linear mixed models was used to examine pre-surgical psychosocial factors predicting post-surgical weight loss (n at 12 months=153, n at 24 months= 130, n at 30 months= 92). Anxiety had a significant interaction effect with time (Est. = −0.01, p = 0.013), indicating that higher anxiety was associated with less weight loss over time. Those with severe anxiety prior to surgery lost the most weight 12 months after surgery, but also regained the most weight 30 months after surgery. Other predictors were not statistically significant. CONCLUSIONS: Anxiety assessed prior to surgery predicted reduced weight loss 30 months after bariatric surgery, after controlling for surgery type, baseline weight, sex, and age. Results highlight the importance of evaluation and treatment of anxiety in pre-surgical bariatric candidates. |
