Objectively measured levels of physical activity (PA) in patients undergoing Roux-en-Y Gastric Bypass (RYGB) surgery remain essentially unchanged from before to one year after surgery. Effects from RYGB on objectively measured levels of PA among women undergoing RYGB and appurtenant children beyond one year post-surgery are unknown. The aim of the present study was to objectively assess longitudinal changes in PA and sedentary time (ST), among women undergoing RYGB and appurtenant children, from three months before to nine and 48 months after maternal surgery.
Thirty women undergoing RYGB and 40 children provided anthropometric measures during home visits and valid accelerometer assessed (Actigraph GT3X+) PA data, three months before and nine and 48 months after maternal RYGB surgery.
Women undergoing RYGB decreased time spent in moderate to vigorous PA (MVPA) with 2.0 min/day (p = 0.65) and increased ST with 14.4 min/day (p = 0.35), whereas their children decreased time spent in MVPA with 13.2 min/day (p = 0.04) and increased ST with 110.5 min/day (p < 0.001), from three months before to 48 months after maternal surgery. Twenty, 27 and 33% of women, and 60, 68 and 35% of children reached current PA guidelines three months before and nine and 48 months after maternal RYGB, respectively.
Objectively measured PA in women remains unchanged, while appurtenant children decrease time spent in MVPA and increase ST, from three months before through nine and 48 months after maternal RYGB. The majority of both women undergoing RYGB and children are insufficiently active 48 months after maternal RYGB.
接受Roux-en-Y胃旁路术（RYGB）的患者经客观测量的身体活动（PA）水平在术前至术后一年基本保持不变。RYGB对接受RYGB手术的女性及其附属子女术后一年以上经客观测量的PA水平的影响尚不清楚。本研究的目的是客观评估接受RYGB手术的女性及其附属子女在母亲手术前三个月至术后9个月和48个月期间PA和久坐时间（ST）的纵向变化。
30名接受RYGB手术的女性和40名儿童在家庭访视期间提供了人体测量数据，并在母亲RYGB手术前三个月、术后9个月和48个月通过有效的加速度计（Actigraph GT3X+）评估PA数据。
接受RYGB手术的女性中度至剧烈PA（MVPA）时间每天减少2.0分钟（p = 0.65），ST时间每天增加14.4分钟（p = 0.35），而她们的子女MVPA时间每天减少13.2分钟（p = 0.04），ST时间每天增加110.5分钟（p < 0.001），从母亲手术前三个月至术后48个月。在母亲RYGB手术前三个月、术后9个月和48个月，分别有20%、27%和33%的女性以及60%、68%和35%的儿童达到了当前的PA指南。
从母亲RYGB手术前三个月到术后9个月和48个月，经客观测量，女性的PA保持不变，而附属子女的MVPA时间减少，ST增加。在母亲RYGB手术48个月后，接受RYGB手术的女性和儿童中的大多数活动量不足。
