The aim of this study was to evaluate the association between the physical activity level in the third trimester and the time of labor onset.
Two hundred and sixty women with low-risk pregnancies, who gave birth at 37 weeks of gestation or beyond, and completed the Pregnancy Physical Activity Questionnaire were included in this prospective, cross-sectional study. According to the gestational age at delivery, the study population was divided into case (≥41 weeks) and control (37-406/7 weeks) groups. The clinical characteristics and the physical activity levels of the two groups were compared. The physical activity levels of the participants were also compared according to the delivery route.
The nulliparity rate (54.3 vs. 21.7%), the median gestational weight gain (10.5 [2-30] vs. 10 [2-25] kg), and the cesarean delivery rate (27.7 vs. 6.6%) were higher in the case group than the control group (p<0.05). While the median level of sedentary activity was higher, the median moderate-intensity activity level and the median household/caregiving activity level were lower in the case group than the control group (p<0.05). The level of sedentary activity was also higher in women who gave birth by a cesarean section than vaginally (p<0.05).
Physical activity in the third trimester was associated with the time of labor onset. Decreased moderate-intensity and household/caregiving activity levels and an increased level of sedentary activity in the last trimester of pregnancy were found in women who gave birth at ≥41 weeks of gestation. A decreased level of sedentary activity was observed in women who gave birth vaginally.
本研究旨在评估孕晚期身体活动水平与分娩发动时间之间的关联。
本前瞻性横断面研究纳入了260例低风险妊娠且在妊娠37周及以后分娩并完成妊娠身体活动问卷的女性。根据分娩时的孕周，将研究人群分为病例组（≥41周）和对照组（37 - 40⁶/₇周）。比较两组的临床特征和身体活动水平。还根据分娩方式比较了参与者的身体活动水平。
病例组的初产率（54.3%对21.7%）、孕期体重增加中位数（10.5 [2 - 30] kg对10 [2 - 25] kg）和剖宫产率（27.7%对6.6%）均高于对照组（p<0.05）。病例组的久坐活动中位数水平较高，而中等强度活动中位数水平和家庭/照护活动中位数水平低于对照组（p<0.05）。剖宫产分娩的女性久坐活动水平也高于阴道分娩的女性（p<0.05）。
孕晚期的身体活动与分娩发动时间有关。在妊娠≥41周分娩的女性中，发现妊娠晚期中等强度和家庭/照护活动水平降低，久坐活动水平增加。阴道分娩的女性久坐活动水平降低。
