减肥手术患者报告术前到术后显著增加体力活动（PA）。然而，目前尚不清楚的是，客观措施是否能证实这些变化。本研究比较了自我报告和基于加速度计的中至高强度PA （MVPA）从术前到术后6个月的变化估计。20例减肥手术患者（65%为腹腔镜可调节胃束带，35%为胃旁路）（46.2±9.8岁，88%为女性，术前BMI = 50.8±9.7 kg/m2），在减肥术前和术后6个月佩戴RT3加速计作为MVPA的客观测量，并完成帕芬巴格体育活动问卷（PPAQ）作为主观测量。计算术前和术后PPAQ和RT3（≥1分钟和≥10分钟）在MVPA中花费的时间（min/周）。自我报告的MVPA从术前到术后增加了5倍（44.6±80.8至212.3±212.4分钟/周；P < 0.005）。相比之下，RT3在≥1分钟（186.0±169.0至151.2±118.3分钟/周）和≥10分钟（41.3±109.3至39.8±71.3分钟/周）发作时MVPA均无显著降低。在术前，根据PPAQ和RT3，在≥10分钟的回合中累积≥150分钟/周的MVPA的参与者百分比相同（10%）。然而，在术后，55%的参与者报告遵守了建议，而根据RT3测量，这一比例为5% （P = 0.002）。从术前到术后6个月，客观测量的MVPA变化似乎比自我报告的变化要小得多。需要更大样本的进一步研究来证实这些发现，并确定自我报告和客观PA测量是否与手术减肥结果存在差异。
Bariatric surgery patients report significant pre- to postoperative increases in physical activity (PA). However, it is unclear whether objective measures would corroborate these changes. The present study compared self-reported and accelerometer-based estimates of changes in moderate-to-vigorous intensity PA (MVPA) from pre- (pre-op) to 6 months postsurgery (post-op). Twenty bariatric surgery (65% laparoscopic-adjustable gastric banding, 35% gastric bypass) patients (46.2 ± 9.8 years, 88% female, pre-op BMI = 50.8 ± 9.7 kg/m2) wore RT3 accelerometers as an objective measure of MVPA and completed the Paffenbarger Physical Activity Questionnaire (PPAQ) as a subjective measure before and 6 months after bariatric surgery. Time (min/week) spent in MVPA was calculated for the PPAQ and RT3 (≥1-min and ≥10-min bouts) at pre-op and post-op. Self-reported MVPA increased fivefold from pre-op to post-op (44.6 ± 80.8 to 212.3 ± 212.4 min/week; P < 0.005). By contrast, the RT3 showed nonsignificant decreases in MVPA for both ≥1-min (186.0 ± 169.0 to 151.2 ± 118.3 min/week) and ≥10-min (41.3 ± 109.3 to 39.8 ± 71.3 min/ week) bouts. At pre-op, the percentage of participants who accumulated ≥150-min/week of MVPA in bouts ≥10-min according to the PPAQ and RT3 was identical (10%). However, at post-op, 55% of participants reported compliance with the recommendation compared to 5% based on RT3 measurement (P = 0.002). Objectively-measured changes in MVPA from pre-op to 6 months post-op appear to be much smaller than self-reported changes. Further research involving larger samples is needed to confirm these findings and to determine whether self-report and objective PA measures are differentially associated with surgical weight loss outcomes.
