Do patients with obesity undergoing bariatric surgery modify their objectively measured physical activity? A systematic review and meta-analysis.

Background: Obesity is a chronic disease associated with adverse outcomes and its prevalence is increasing, which makes it a concern. One of the obesity treatment options is bariatric surgery, which effectively reduces calorie absorption and total body mass, but its effects on physical activity (PA) levels need to be clarified, considering the protective effect of the PA against cardiovascular disease, independently of the weight loss alone.

Objectives: To carry out a systematic review and meta-analysis of observational studies that evaluated PA in pre- and post-bariatric surgery periods through objective evaluation.
