BACKGROUND: Many studies using self-reported physical activity (PA) assessment tools have suggested there is an increase in PA after bariatric surgery.
OBJECTIVES: Our aim was to assess PA and sedentary behavior before bariatric surgery and at 6 months after, using subjective and objective tools.
SETTING: Bariatric surgery candidates were recruited from a single center.
METHODS: Demographic data, medical history, current medications, and anthropometric measurements were recorded. Participants were asked to complete a PA and lifestyle questionnaire and to wear an accelerometer on their nondominant wrist. Data were collected before and at 6 months after surgery.
RESULTS: Twenty-two participants were included (17 gastric bypass; 4 sleeve gastrectomy; 1 intragastric balloon). Mean age was 46 years and the majority were female (72%). At a median of 6.3 months follow-up, there were significant reductions in measures of body fatness with a mean reduction of 27 kg in weight. The majority of daytime (12.5±1.1 out of 16 h) was spent in sedentary behavior presurgery with little change postsurgery (12.2±1.2; P = .186). Objectively measured mean moderate-vigorous PA did not change significantly from pre- to postsurgery (mean 11.5±13.9 and 11.6±13.1 min/d, respectively; P = .971). Self-reported total nonoccupational PA did not change significantly (P = .390).
CONCLUSIONS: The majority of bariatric surgery candidates were physically inactive presurgery, and there was no significant change in either subjectively or objectively measured PA at follow-up. This patient group may benefit from objective PA assessment and interventions aimed at increasing PA.
