Physical Activity in Gastric Bypass Patients: Associations with Weight Loss and Psychosocial Functioning at 12-Month Follow-Up
Open accessAbstract
Background This study examined self-reported frequency and intensity of physical activity in gastric bypass patients, and the relationship between physical activity and weight loss and psychosocial outcomes during 12-month postoperative follow-up.Methods Participants were 131 obese patients who underwent gastric bypass surgery and completed psychometrically established measures assessing physical activity, depression, and physical and mental health preoperatively and at a 12-month follow-up assessment.Results Preoperatively, 62.6% of patients reported at least one episode of a minimum of 15 minutes of physical activity per week. This figure increased to 92.4% at 12-month postoperative follow-up. Both the frequency and intensity levels of physical activity episodes increased significantly from preoperative to 12-month postoperative assessments. Hierarchical regression analyses, controlling for demographic variables and preoperative body mass index (BMI), revealed that the intensity of physical activity was significantly associated with postoperative weight loss at 12-month follow-up. Both the frequency and intensity of physical activity were significantly associated with depression, and physical and mental well-being at the 12-month postoperative follow-up.Conclusion Gastric bypass patients increase both the frequency and intensity of their physical activity during the first 12 months postoperatively. Higher postoperative intensity levels of physical activity are associated with better weight loss outcomes while both increased frequency and intensity levels of physical activity are associated with better psychosocial outcomes.

Only 10-24% of post-bariatric surgery patients met the physical activity guidelines for health promotion (≥150 min/week or moderate-to-vigorous physical activity in bouts of ≥10 min).
“only 10–24% of post-BS patients met the PA guidelines for health promotion (i.e., ≥ 150 min/week or moderate-to-vigorous PA in bouts of ≥ 10 min) [59].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
