Changes in Physical Activities and Body Composition after Roux-Y Gastric Bypass Surgery

Changes in Physical Activities and Body Composition after Roux-Y Gastric Bypass Surgery Purpose Given the importance of physical activities for health outcomes, it is still unclear whether bariatric surgery per se and the standard care after surgery would result in an increase of physical activity level. This study aimed to determine physical activities preoperatively and at 6 and 12 months postoperatively among female patients who underwent bariatric surgery, and to investigate its relationship with body composition changes. Material and Methods Thirty-four women who had Roux-Y gastric bypass (RYGB) surgery completed the study. Physical activity was measured objectively for 7 consecutive days by using an ActiGraph GT3X+ accelerometer. Body composition was estimated by using multifrequency bioimpedance analysis. Results The percentage of time spent in moderate-to-vigorous physical activity (MVPA) changed significantly from preopera- tively to 6 months postoperatively; however, no difference was observed at 12 months. No significant changes were detected for other physical activity variables. Multivariable regression analysis suggested that the percentage of time spent in sedentary activity was associated with fat-free mass loss at 6 months (β = − 0.323; 95% CI = − 0.649 to 0.003) and 12 months (β = − 0.510; 95% CI = − 0.867 to − 0.154) postoperatively. Conclusion The overall MVPA increased at 6 months http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Obesity Surgery Springer Journals

Abstract

Purpose Given the importance of physical activities for health outcomes, it is still unclear whether bariatric surgery per se and the standard care after surgery would result in an increase of physical activity level. This study aimed to determine physical activities preoperatively and at 6 and 12 months postoperatively among female patients who underwent bariatric surgery, and to investigate its relationship with body composition changes. Material and Methods Thirty-four women who had Roux-Y gastric bypass (RYGB) surgery completed the study. Physical activity was measured objectively for 7 consecutive days by using an ActiGraph GT3X+ accelerometer. Body composition was estimated by using multifrequency bioimpedance analysis. Results The percentage of time spent in moderate-to-vigorous physical activity (MVPA) changed significantly from preopera- tively to 6 months postoperatively; however, no difference was observed at 12 months. No significant changes were detected for other physical activity variables. Multivariable regression analysis suggested that the percentage of time spent in sedentary activity was associated with fat-free mass loss at 6 months (β = − 0.323; 95% CI = − 0.649 to 0.003) and 12 months (β = − 0.510; 95% CI = − 0.867 to − 0.154) postoperatively. Conclusion The overall MVPA increased at 6 months
