Physical activity is an important lifestyle target for post-bariatric surgery patients that may be associated with improved weight loss, lower incidence of weight regain, and improvements in selective health-related outcomes. Despite these benefits, engagement in physical activity in less than optimal in post-bariatric surgery patients. Identifying psychosocial variables associated with physical activity may lead to the development of interventions that better address the challenges to participating in physical activity experienced after bariatric surgery, and enhance physical activity in these patients.

PURPOSE: To examine associations between selective psychosocial variables and physical activity in patients who had undergone bariatric surgery within the past 2 years.

METHODS: Eighty-three patients who had undergone bariatric surgery (age 44.0±11.8 years, BMI 44.0±11.8 kg/m2) self-reported current physical activity and select psychosocial constructs. Additionally, participants provided retrospective information on physical activity and select psychosocial constructs prior to surgery.

RESULTS: Subjects increased leisure-time physical activity by a median 508.00 (48.00, 1138.00) kcal/week from pre- to post-bariatric surgery. Physical activity was significantly associated with a number of pre- and post-surgical psychosocial constructs in the bivariate analyses; however, only social support, fitness orientation, physical function and self-classified weight emerged as significant predictors of physical activity engagement in subsequent stepwise regression analyses.

CONCLUSIONS: These findings may suggest that both pre- and post-bariatric surgery intervention may need to target important constructs that include the encouragement of social support, strategies to enhance the effort individuals put forward to engage in physical activity, focus on enhancing physical function, and awareness of weight status with the goal of improving engagement in physical activity.
