Background: Bariatric surgery is the only effective long-term treatment for obesity; however, some studies have observed post-surgical problems related to alcohol use. At present, no large-scale studies have examined the prevalence and correlates of either increases in alcohol use or maintenance of frequent alcohol use post-surgery, both of which may increase risk of post-surgical alcohol-related problems. Further, it is unclear as to how post-surgical alcohol use relates to weight loss outcomes. Thus, the current study examined whether type of surgery, tobacco use, and severity of depression predicted increased drinking or sustained frequent drinking following bariatric surgery, and whether frequency of post-surgical drinking related to weight loss outcomes. Method: Participants were 42,228 individuals who underwent bariatric surgery (20.4% male). Of these patients, 54.2% received Roux-en-Y Gastric Bypass (RYGBP), and 45.8% received Adjustable Gastric Banding (AGB). Single-item rating scales of severity of depression and the frequency of pre- and post-surgical (M=351 days following surgery; SD=145) alcohol and tobacco use were entered directly into the Bariatric Outcomes Longitudinal Database by their physician. Two logistic regression analyses were performed to examine predictors of sustained frequent drinking (i.e., ¿¿¿¿¿¿¿frequent¿¿¿¿¿¿¿ drinking pre- and post-surgery) and increased drinking post-surgery, respectively. A multivariate linear regression was used to examine whether frequency of post-surgical alcohol use significantly predicted percent BMI change. Results: Fifty-seven percent of those who drank frequently before surgery (n = 479) sustained frequent drinking post-surgery. Of those with infrequent or no alcohol use prior to surgery (n = 41,749), 1.9% increased drinking post-surgery. Undergoing AGB was associated with a greater likelihood of both increased drinking (p < 0.05, OR = 1.15) and sustained frequent drinking (p < .01, OR = 2.44) post-surgery. Neither pre-surgical tobacco use nor severity of pre-surgical depression were significant predictors of increased drinking or sustained frequent drinking post-surgery. In the entire sample, frequency of post-surgical drinking was not related to percent BMI change. Conclusion: AGB may put an individual at increased risk for sustained frequent drinking or increased drinking when compared to RYGBP. Contrary to expectations, depression and smoking were not significantly related to post-surgical drinking. In addition, the current findings suggest that post-surgical alcohol use may not be associated with significantly poorer weight loss outcomes. While the current findings address limitations of prior studies, additional work is needed to examine other relevant factors influencing post-surgical alcohol use, particularly in the context of problematic use.
