虽然建议进行中等至剧烈强度的体力活动（MVPA），但对怀孕期间久坐行为（SED）的研究有限。我们进行了一项前瞻性队列研究，以描述在每个妊娠期的SED和活动的客观测量模式。女性佩戴大腿（activPAL 3）和腰部（Actigraph GT 3x）活动监测器。使用似然比检验比较了三个月的SED和活动，并使用基于组的轨迹进行了描述。探索性分析将SED和活动轨迹与不良妊娠结局（APO）和妊娠期体重过度增加（GWG）相关。孕妇（n=105;平均（SD）年龄=31（5）岁;孕前BMI=26.2（6.6）kg/m2）的平均SED为9.7、9.5、和9.5小时/天（p=0.062）。一些活动在妊娠期不同：站立（增加，p=0.01），踏步（在妊娠后期最高，p=0.04），步数/天（在妊娠后期最高，p=0.008）和MVPA（降低，p<0.001）。延长SED（发作≥30分钟）和插管MVPA（≥10分钟）稳定（p>0.05）。在探索性分析中，较高的SED和较低的站立、踏步和步数/天轨迹与APO的几率增加相关（p<0.05）。没有轨迹与过度GWG相关。孕妇在整个怀孕期间每天表现出稳定的SED近10小时。未来的研究评估SED跨怀孕和载脂蛋白O的风险是必要的。
Though moderate-to-vigorous intensity physical activity (MVPA) is recommended, limited research exists on sedentary behavior (SED) during pregnancy. We conducted a prospective cohort study to describe objectively-measured patterns of SED and activity during each trimester of pregnancy. Women wore thigh- (activPAL3) and waist-mounted (Actigraph GT3x) activity monitors. SED and activity were compared across trimesters using likelihood ratio tests and described using group-based trajectories. Exploratory analyses associated SED and activity trajectories with adverse pregnancy outcomes (APOs) and excessive gestational weight gain (GWG). Pregnant women (n=105; mean (SD) age=31 (5) years; prepregnancy BMI=26.2 (6.6) kg/m2) had mean SED of 9.7, 9.5., and 9.5 hr per day (p=0.062) across trimesters, respectively. Some activities differed across trimesters: standing (increased, p=0.01), stepping (highest in 2nd trimester, p=0.04), steps/day (highest in 2nd trimester, p=0.008), and MVPA (decreased, p<0.001). Prolonged SED (bouts ≥30 minutes) and bouted MVPA (≥10 minutes) were stable (p>0.05). In exploratory analyses, higher SED and lower standing, stepping, and steps/day trajectories were associated with increased odds of APOs (p<0.05). No trajectories were associated with excessive GWG. Pregnant women exhibited stable SED of nearly 10 hr per day across pregnancy. Future research evaluating SED across pregnancy and APO risk is warranted.
