Objective

Physical activity (PA) is an integral component of the medical management of patients following bariatric surgery as it is thought to be associated with biopsychosocial outcomes, including mood and physical function. This study examined self-reported PA (SR-PA) and psychosocial correlates among patients with loss-of-control (LOC) eating following bariatric surgery.

Method

Participants were 145 patients (82.8% female, 53.8% White) who were experiencing recurrent LOC-eating approximately six months after having undergone sleeve gastrectomy surgery. Body mass index (BMI) and percent total weight loss were calculated using measured height and weight.. Eating-disorder symptoms were assessed using the Eating Disorder Examination-Bariatric Surgery Version interview and participants completed established self-report measures assessing PA, health-related quality of life (mental and physical functioning domains), weight-related disability, and depression.

Results

Approximately two-thirds of the participant group reported at least one bout (≥15 min) of moderate PA per week. SR-PA was significantly negatively associated with LOC-eating frequency, dissatisfaction with weight and shape, depression, and weight-related disability, and was significantly positively correlated with physical functioning. After adjusting for depression and BMI, SR-PA remained significantly associated with better physical functioning but no longer contributed significant independent variance to eating-disorder psychopathology or weight-related disability.

Conclusions

Among patients with LOC-eating following bariatric surgery, an inactive lifestyle is common. Greater PA was associated with better psychosocial functioning and finding ways to promote greater engagement with recommended levels of PA following bariatric surgery may contribute to improved bariatric surgery outcome.

饮食失控患者减肥手术后的身体活动与心理社会相关性

目的

体力活动（PA）是减肥手术后患者医疗管理中不可或缺的组成部分，因为据认为它与包括情绪和身体功能在内的生物心理社会后果相关。这项研究检查了减肥手术后饮食失控（LOC）患者中自我报告的PA（SR-PA）和心理社会相关性。

方法

参加者有145例（女性82.8％，白人53.8％是白人），他们在进行了袖胃切除手术后大约六个月经历了LOC反复发作。使用测得的身高和体重来计算体重指数（BMI）和总体重减轻百分率。饮食失调症状通过饮食失调检查-aria门手术版本访谈进行评估，参与者完成了建立的自我报告措施，评估了与健康相关的PA生活质量（精神和身体功能领域），与体重有关的残疾和抑郁。

结果

大约三分之二的参与者组每周至少报告一次中度PA发作（≥15分钟）。SR-PA与进食LOC的频率，对体重和形状的不满意，抑郁和与体重有关的残疾呈显着负相关，与身体功能呈显着正相关。在对抑郁症和BMI进行调整后，SR-PA仍然与更好的身体机能显着相关，但不再对饮食失调的精神病理学或体重相关的残疾造成明显的独立差异。

结论

在减肥手术后进食LOC的患者中，不活跃的生活方式很常见。较高的PA与更好的心理社会功能有关，在减肥手术后寻找促进以推荐的PA水平更好地参与的方法可能有助于改善减肥手术的效果。
