title: Tobacco use and substance use disorders as predictors of postoperative weight loss 2 years after bariatric surgery.
abstract: Although evaluations of tobacco and substance use disorders (SUDs) are required before bariatric surgery, the impact of these factors on postsurgical outcomes is unclear. This study describes (1) the prevalence of tobacco and SUDs in 61 veterans undergoing bariatric surgery, (2) associations between presurgical tobacco use and postsurgical weight loss, and (3) relationships between presurgical SUDs and postsurgical weight loss. Height, weight, tobacco, and SUDs were assessed from medical charts at presurgery and 6, 12, and 24 months postsurgery. Thirty-three patients (55%) were former or recent tobacco users; eight (13%) had history of SUDs. All patients who quit smoking within 6 months before surgery resumed after surgery, which was associated with increased weight loss at 6 and 12 months. Presurgical SUDs were related to marginally worse weight loss at 12 and 24 months. Bariatric surgery candidates with history of smoking and/or SUDs might benefit from additional services to improve postsurgical outcomes.
