Meeting physical activity (PA) recommendations is positively associated with health-related quality of life (HRQoL), but it is still unclear whether PA (specifically objectively measured) is associated with HRQoL in bariatric surgery candidates, both before and after surgery. Thus, the aim of this study was to examine the cross-sectional association between meeting objectively measured PA recommendations and HRQoL before and after Roux-en-Y gastric bypass (RYGB) surgery.
Sixty-six women undergoing RYGB with pre-surgery and 62 women with post-surgery valid PA and HRQoL data were included from the control group of a RCT study aiming at improving HRQoL and PA post-RYGB surgery. Measures before and 12 months after RYGB included the Short Form Health Survey (SF-36) and objectively measured PA, sedentary time (ST), and step counts with GT3X+ accelerometers. Multiple linear regression models were used to analyze the associations between PA and HRQoL.
Participants who engaged in more than 150 min of moderate to vigorous PA (MVPA)/week (PA recommendations) had considerably higher SF-36 scores (HRQoL) than those who did not, both pre and 12-month post-surgery, with greatest difference in the subscale bodily pain, 15.5 (p = 0.021) higher score (higher scores means less pain) pre-surgery and a 19.7 (p = 0.004) higher score post-surgery. Higher LPA and step counts and lower ST also showed positive associations in some of the subscales of SF-36.
Meeting the PA recommendations and overall engaging in more PA was associated with higher HRQoL, pre-, and post-RYGB surgery, highlighting the importance of PA both pre- and post-surgery.
满足身体活动（PA）建议与健康相关的生活质量（HRQoL）呈正相关，但仍不清楚 PA（特别是客观测量）是否与肥胖症手术候选者的 HRQoL 相关，包括手术前和手术后。因此，本研究的目的是检查在 Roux-en-Y 胃旁路术（RYGB）手术前后，符合客观测量 PA 建议与 HRQoL 之间的横断面关联。
从旨在改善 RYGB 手术后 HRQoL 和 PA 的 RCT 研究的对照组中，纳入了 66 名接受 RYGB 手术的女性（术前）和 62 名具有术后有效 PA 和 HRQoL 数据的女性。在 RYGB 手术前后，采用简短健康调查问卷（SF-36）和 GT3X+加速度计客观测量 PA、久坐时间（ST）和步数。采用多元线性回归模型分析 PA 与 HRQoL 之间的关系。
每周进行超过 150 分钟中等到剧烈 PA（MVPA）（PA 建议）的参与者，无论是在术前还是术后 12 个月，SF-36 评分（HRQoL）都明显更高，术前在身体疼痛子量表中差异最大，高 15.5（p=0.021）分，术后高 19.7（p=0.004）分。更高的 LPA 和步数以及更低的 ST 也与 SF-36 的一些子量表呈正相关。
符合 PA 建议并总体上更多地进行 PA 与 RYGB 手术前后更高的 HRQoL 相关，强调了 PA 在手术前后的重要性。
