Bariatric surgery produces weight loss in part by impacting appetite and eating behavior. Research suggests physical activity (PA) assists with regulation of appetite and eating during non-surgical weight loss, although whether PA carries similar benefits in the context of bariatric surgery is unknown.
Evaluate associations of moderate-to-vigorous intensity PA (MVPA) and sedentary time (ST) with appetite sensations (hunger [homeostatic/hedonic], satiety) and eating regulation behaviors (restraint, disinhibition) before and during the initial year following bariatric surgery.
Adult bariatric patients received an accelerometer to measure MVPA/ST and a smartphone to complete appetite/eating ratings at four semi-random times daily for 10 days at pre- and 3-, 6-, and 12-months post-surgery. Data were analyzed using generalized linear mixed models.
Higher MVPA levels related to more satiety across time ( = 0.045) and more restraint at 3-months post-surgery ( < 0.001). At pre-surgery, higher MVPA levels also related to more disinhibition ('s < 0.01), although participants reported more disinhibition on days they performed less MVPA than usual ( = 0.017). MVPA did not relate to hunger. Lower ST levels related to more hedonic hunger ( = 0.003), especially at 12-months post-surgery ( < 0.001), and participants reported more homeostatic hunger on days they accumulated more ST than usual ( = 0.044). Additionally, higher ST levels related to more disinhibition at 3-months post-surgery ('s < 0.01) and lower restraint at pre-surgery ('s < 0.05). ST did not relate to satiety.
This study is the first to show that MVPA and ST each associate with appetite and eating regulation in daily life before and during post-surgical weight loss. Results, while preliminary and requiring experimental confirmation, highlight potential for targeting bariatric patients' activity behaviors to enhance modulation of appetite, control of food intake, and resistance to overeating.
减肥手术部分通过影响食欲和饮食行为来实现体重减轻。研究表明，体育活动（PA）有助于在非手术减肥期间调节食欲和饮食，尽管在减肥手术背景下PA是否具有类似益处尚不清楚。
评估减肥手术前及术后第一年期间，中等至剧烈强度的PA（MVPA）和久坐时间（ST）与食欲感觉（饥饿[稳态/享乐性]、饱腹感）以及饮食调节行为（克制、去抑制）之间的关联。
成年减肥患者佩戴加速度计以测量MVPA/ST，并使用智能手机在术前以及术后3个月、6个月和12个月时，连续10天每天在四个半随机时间完成食欲/饮食评分。数据使用广义线性混合模型进行分析。
较高的MVPA水平在整个时间段内与更多的饱腹感相关（β = 0.045），并且在术后3个月与更多的克制相关（P < 0.001）。在术前，较高的MVPA水平也与更多的去抑制相关（P < 0.01），尽管参与者在MVPA比平时少的日子里报告了更多的去抑制（P = 0.017）。MVPA与饥饿无关。较低的ST水平与更多的享乐性饥饿相关（β = 0.003），尤其是在术后12个月（P < 0.001），并且参与者在ST比平时积累更多的日子里报告了更多的稳态饥饿（P = 0.044）。此外，较高的ST水平在术后3个月与更多的去抑制相关（P < 0.01），在术前与较低的克制相关（P < 0.05）。ST与饱腹感无关。
本研究首次表明，MVPA和ST在术后减肥前及期间均与日常生活中的食欲和饮食调节相关。结果虽然初步且需要实验证实，但突出了针对减肥患者的活动行为以增强食欲调节、控制食物摄入和抵抗暴饮暴食的潜力。
