摘要

背景。妊娠期是检查与新生儿结局相关的可改变的孕产妇行为的关键时期,以便采取预防措施防止儿童肥胖。目标。本研究旨在探讨通过母体体育活动影响新生儿大小和身体组成的途径。方法。从一项妊娠队列研究中纳入了具有客观测量体力活动数据的参与者的子样本。在怀孕期间第一次就诊时收集社会人口统计数据。在每次访问时计算妊娠期体重增加(GWG),并评估妊娠期糖尿病、高血压和HIV的存在。在妊娠14 - 18周和29 - 33周时,使用臀部佩戴的三轴加速度计测量身体活动。分娩时测量胎龄、出生体重和体长,分析新生儿体成分。以体重与长度比(WLR)或脂肪质量指数(FMI)为结果,运行结构方程模型(SEM)。结果。本研究共纳入84名参与者,新生儿亚样本(n=45)也有FMI数据。大多数(66%)母亲在第一次就诊时表现为超重或肥胖,每周平均体重增加0.35(19)公斤。扫描电镜显示,只有分娩胎龄和久坐时间与WLR呈正相关。步数与GWG直接相关(ß=-0.02, p=0.01),与胎龄直接相关(ß=0.16, p=0.04),因此与胎儿腹围减小间接相关。结论。这项研究表明,增加每日步数和减少久坐行为可能对孕产妇健康、分娩结果和新生儿体型产生有益影响。

Physical activity and sedentary behaviours during pregnancy are associated with neonatal size at birth
Background. Pregnancy is a crucial time to examine modifiable maternal behaviours associated with neonatal outcomes so that preventative measures can be taken against childhood obesity. Objectives. This study aimed to examine the pathways through which maternal physical activity impacted neonatal size and body composition. Methods. A subsample of participants who had objectively measured physical activity data were included from a pregnancy cohort study. Sociodemographic data were collected at the first visit during pregnancy. Gestational weight gain (GWG) was calculated at each visit, and the presence of gestational diabetes, hypertension and HIV were assessed. Physical activity was measured using a hip-worn triaxial accelerometer, at 14 - 18 weeks’ and 29 - 33 weeks’ gestation. At delivery, gestational age, birthweight and length were measured and neonatal body composition was analysed. A structural equation model (SEM) was run with either weight-to-length ratio (WLR) or fat mass index (FMI) as the outcome. Results. A total of 84 participants were included in this study, and a subsample of neonates (n=45) also had FMI data. Most (66%) mothers presented as overweight or obese at their first visit, and gained on average 0.35 (19) kg per week. The SEM showed that only gestational age at delivery and sedentary time were positively associated with WLR. Step count was directly associated with GWG (ß=-0.02, p=0.01), and with gestational age (ß=0.16, p=0.04), and was therefore indirectly associated with decreased fetal abdominal circumference. Conclusion. This study showed that increasing daily step count and decreasing sedentary behaviour could have beneficial effects on maternal health as well as delivery outcomes and neonatal size.
