ABSTRACT
BACKGROUND: To compare the barriers to exercise and its associated factors among patients in the pre- and postoperative periods of bariatric surgery. METHODS: Cross-sectional study with patients who were split into preoperative (n = 81) and postoperative (n = 209) groups. It was collected sociodemographic characteristics, and the Exercise Benefits Barriers Scale was adopted in order to identify the barriers related to exercise practice. Chi-square, Mann-Whitney, and Poisson regression were applied for comparisons and associations. RESULTS: The postoperative group had a lower score on the barrier scale, except for the lack of time subdimension. In the preoperative, the subjects were considered physically active (p = 0.03), and those over 42 years old (p < 0.001) had the lowest score in lack of time subdimension. Those with a body mass index (BMI) higher than 36.89 kg/cm2 had a higher overall score on the scale (p < 0.001), also in the lack of time (p = 0.003) and physical effort subdimensions (p < 0.001). Those with higher education scored more in the lack of time (p = 0.014) and family discouragement subdimensions (p = 0.034). In the postoperative, the participants considered active had the lowest score on the general scale, as well as in all subdimensions (p < 0.001), and the ones with higher education presented better scores in physical effort subdimension (p = 0.041). CONCLUSIONS: The preoperative group had a higher score of barriers to practice exercises related to physical effort, environment, and family discouragement, when compared to the postoperative. The factors associated were physical inactivity, BMI over 36.89 kg/cm2, age 42 years old or under, and higher education.
