更大的感知社会支持（PSS）与代谢和减肥手术（MBS）后体重减轻，活动行为和饮食调节的更有利变化相关。然而，研究依赖于通用的回顾性PSS测量，PSS水平的稳定性以及随时间推移与体重减轻和体重相关行为的关系尚不清楚。使用基于智能手机的生态瞬时评估，该研究评估了MBS前至MBS后1年的日常体重管理重点PSS变化以及与MBS前和MBS后最初一年期间的体重减轻，设备测量的活动行为和饮食调节的相关性。成人MBS患者（n = 71）接受（1）加速度计测量每日中到剧烈强度体力活动（MVPA）和久坐时间（ST）分钟/天，（2）智能手机在术前和术后3、6和12个月每天4个半随机时间完成早晨体重集中的PSS评级和饮食调节（饮食限制/去抑制）评级，持续10天。广义线性混合模型分析了PSS与总体重减轻（%TWL）和活动/饮食结果的相关性。参与者平均报告了相对稳定的中度至高度PSS（1至5个量表为3.98）。感知社会支持与%TWL、MVPA或ST无关。PSS较高的参与者报告的去抑制和抑制程度低于PSS较低的参与者（p < 0.05）;然而，参与者报告的抑制程度高于PSS低于其平时水平的日子（p = 0.009）。MBS患者的平均PSS水平随着时间的推移而稳定。随着时间的推移，较高的PSS水平与对暴饮暴食线索（去抑制）和限制食物摄入（抑制）的认知控制的更大抵抗力相关。此外，当PSS水平低于平时时，参与者报告了更高的约束力。总体而言，在术后最初一年，以体重为重点的PSS似乎在调节饮食行为方面比MBS患者的活动行为或体重减轻更重要。NCT02777177。
Greater perceived social support (PSS) is associated with more favorable changes in weight loss, activity behaviors, and eating regulation after metabolic and bariatric surgery (MBS). However, studies have relied on generic, retrospective PSS measures, and stability of PSS levels and relations with weight loss and weight‐related behaviors over time is unknown. Using smartphone‐based Ecological Momentary Assessment, this study evaluated pre‐to 1‐year post‐MBS changes in daily weight management‐focused PSS and associations with weight loss, device‐measured activity behaviors, and eating regulation before and during the initial year after MBS. Adult MBS patients (n = 71) received (1) an accelerometer to measure daily moderate‐to‐vigorous intensity physical activity (MVPA) and sedentary time (ST) minutes/day, and (2) a smartphone to complete morning weight‐focused PSS ratings and eating regulation (dietary restraint/disinhibition) ratings at four semi‐random times daily for 10 days at pre‐ and 3, 6, and 12‐month postoperative. Generalized linear mixed models analyzed the associations of PSS with total weight loss (%TWL) and activity/eating outcomes. Participants on average reported relatively stable moderate‐to‐high PSS (3.98 on one to five scale) across assessments. Perceived social support was not related to %TWL, MVPA, or ST. Participants with higher PSS reported lower disinhibition and higher restraint than those with lower PSS (ps < 0.05); however, participants reported higher restraint on days that PSS was lower than their usual levels (p = 0.009). MBS patients on average had stable PSS levels across time. Higher PSS levels were associated with greater resistance to overeating cues (disinhibition) and cognitive control to restrict food intake (restraint) over time. Additionally, participants reported higher restraint when PSS levels were lower than usual. Overall, weight‐focused PSS appeared to hold greater importance in relation to regulating eating behavior than engaging in activity behaviors or weight loss among MBS patients during the initial postoperative year.
