Abstract

Background

Promoting habitual physical activity (PA) among bariatric patients is crucial for long-term surgery success, yet it poses a significant challenge for healthcare practitioners.

Objectives

This randomized controlled trial (RCT) aimed to examine the effectiveness of a theory-based behavioral intervention on PA level in post-metabolic bariatric surgery (MBS) patients.

Setting

University Hospital, Israel

Methods

Forty-four patients undergoing MBS were randomized to the intervention (n = 22) or control group (n = 22). The intervention group received a 6-month PA counseling program based on self-determination theory (SDT) and the 5 A’s framework, while the control group received usual care. PA level and self-efficacy for exercise (SEE) were assessed pre- (baseline, preintervention) and postoperatively (14 and 28 weeks follow-ups). Anthropometrics, physical function, cardiovascular, and biochemical outcomes were measured at all time points.

Results

The intervention group showed greater increases in PA levels across time compared to the control group. A significant increase in step counts from baseline to 14 weeks was observed (P = .003). Significant differences favoring the intervention group were observed in self-reported PA changes from baseline to 14- and 28-week follow-ups (P = .020 and P = .024, respectively). Additionally, Physical function, as assessed by the 6-minute walk test (6MWT) and the 5 sit-to-stand (5STS) test, significantly improved in the intervention group throughout the follow-up period (P < .05 for all), However, no between-group differences were observed in SEE, anthropometrics, cardiovascular, or biochemical parameters.

Conclusions

A 6-month behavioral intervention post-MBS significantly enhanced patients' PA levels and physical function. Given its theory-based approach and structured protocol, this intervention could be disseminated to support MBS clinicians and centers. Further research with longer follow-up period is warranted to confirm these findings and assess the long-term effects.

为期 6 个月的体育锻炼行为干预对代谢性减肥手术后患者的影响：随机对照试验

促进肥胖症患者养成体育锻炼（PA）的习惯对于手术的长期成功至关重要，但这对医疗从业人员来说却是一项巨大的挑战。这项随机对照试验（RCT）旨在研究基于理论的行为干预对代谢性减肥手术（MBS）术后患者体育锻炼水平的影响。以色列大学医院 44 名接受代谢性减肥手术的患者被随机分配到干预组（22 人）或对照组（22 人）。干预组接受为期 6 个月的以自我决定理论（SDT）和 5 A 框架为基础的 PA 辅导计划，而对照组则接受常规护理。对干预前（基线，干预前）和干预后（14 周和 28 周随访）的运动量和运动自我效能（SEE）进行评估。在所有时间点都对人体测量学、身体功能、心血管和生化结果进行了测量。与对照组相比，干预组在不同时间段的运动量增加幅度更大。从基线到 14 周，观察到步数明显增加 ( = .003)。从基线到 14 周和 28 周的随访期间，干预组在自我报告的运动量变化方面有明显差异（分别为 = .020 和 = .024）。此外，通过 6 分钟步行测试 (6MWT) 和 5 次坐立测试 (5STS) 评估，干预组在整个随访期间的身体机能明显改善（均小于 0.05），但在 SEE、人体测量、心血管或生化指标方面未观察到组间差异。MBS后为期6个月的行为干预显著提高了患者的PA水平和身体功能。鉴于其基于理论的方法和结构化的方案，该干预措施可用于支持MBS临床医生和中心。为了证实这些研究结果并评估其长期效果，有必要进行更长时间的随访研究。
