Leisure-Time Physical Activity Patterns and Predictors in Patients Before and After Metabolic and Bariatric Surgery:...

To describe patterns and predictors of leisure-time physical activity (LTPA) in patients awaiting (PRE) and after (POST) metabolic and bariatric surgery (MBS).

A cross-sectional study was conducted with 180 participants (PRE: n = 63, POST: n = 117). Data were collected through a structured questionnaire on demographic and clinical variables, LTPA patterns, and professional guidance. Descriptive statistics, chi-square and Fisher's exact tests, and binomial logistic regression were used.

The sample was predominantly female (83.3%), with a mean age of 43.16 ± 11.13 years and BMI of 40.85 ± 10.79 kg/m². In the PRE group, 70% were classified as inactive, with 44.3% reporting no physical activity (PA). Walking or running outdoors was the most common activity. Most active participants (88.2%) exercised under professional supervision versus 27.8% of inactive ones [X²(1) = 13.05; p < 0.001]. In the POST group, 57% were inactive, although 43.1% engaged in at least one type of LTPA. Walking or running was most common overall (40.2%), while resistance training predominated among active individuals (60%). Indoor settings were preferred for LTPA (63.4%). Being accompanied by an exercise professional significantly increased the odds of being active (OR = 4.57, 95% CI: 1.31-15.88, p = 0.017).

LTPA participation and characteristics differ considerably between PRE and POST MBS groups. Receiving guidance from an exercise professional was significantly associated with higher PA levels. These findings highlight the importance of developing tailored LTPA programs that include professional support to encourage PA among MBS patients.
