Barriers to Physical Exercise and Associated Factors in the Pre- and Postoperative Periods of Bariatric Surgery.

Abstract

To compare the barriers to exercise and its associated factors among patients in the pre- and postoperative periods of bariatric surgery. 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. 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 42years old (p< 0.001) had the lowest score in lack of time subdimension. Those with a body mass index (BMI) higher than 36.89kg/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). 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 36.89kg/cm2, age 42years old or under, and higher education.
