旨在预防产前并发症的体力活动（PA）干预措施的重点是增加中度PA产生矛盾的结果。很少关注妊娠期间的睡眠、久坐行为（SB）、轻度活动或每日总PA的评估。这项前瞻性纵向研究的目的是：1）客观地量化和比较妊娠中期和妊娠晚期习惯性PA和SB; 2）评估符合产前PA指南的妇女与不符合产前PA指南的妇女的活动模式差异。46名参与者在妊娠第18周和第35周期间佩戴2个PA监测仪（SenseWear® Mini和activPAL™）。我们比较了符合和不符合PA指南的妇女在第二和第三孕期的睡眠时间、姿势分配、每日步数和PA的差异。在妊娠后期，30%的女性一天（24小时）是完全睡眠; 52% SB; 13%轻度; 3%中度; 0%剧烈PA。轻度（P = 0.05）、剧烈（P = 0.02）和中度-剧烈PA（MET-分钟; P = 0.02）降低，SB有增加的趋势（P = 0.07）。其他强度的活动和睡眠持续时间没有显着变化。在第18周和第35周，分别只有39%和37%的参与者每晚睡眠时间在7-9小时之间。分别有46%（n = 21）和28%（n = 13）的参与者在妊娠第2和第3个月期间符合产前PA指南。第18周，符合PA指南的女性与不符合PA指南的女性在总睡眠、SB或轻度PA方面没有差异;符合指南的女性的总PA显着更大。在第35周，符合PA指南的妇女比不符合指南的妇女SB显著减少（P < 0.005）。这项研究表明，孕妇花了大部分的时间在SB。在整个怀孕期间，总活动的显着减少可能是由于，部分是由于轻PA和增加SB的变化。根据我们的样本的生活方式，无论在怀孕中期满足PA指南，在SB上花费的时间没有显着差异，然而，在妊娠晚期满足PA建议可能会减少SB。未来的干预措施应通过增加轻度和中度PA而不是自愿运动来减少SB。
Physical activity (PA) interventions designed to prevent prenatal complications have focused on increasing moderate PA yielding conflicting results. Minimal attention has focused on the evaluation of sleep, sedentary behavior (SB), light activity or total daily PA during pregnancy. The purpose of this prospective, longitudinal study was to 1) objectively quantify and compare habitual PA and SB during the 2nd and 3rd trimester; and 2) evaluate differences in activity patterns for women meeting prenatal PA guidelines versus those that did not. Forty-six participants wore 2 PA monitors (SenseWear® Mini and activPAL™) during week 18 and week 35 of pregnancy. We compared differences in sleep duration, postural allocation, daily steps, and PA between the 2nd and 3rd trimester and for women who met and did not meet PA guidelines. During the 2nd trimester, 30% of the women’s day (24-hours) was total sleep; 52% SB; 13% light; 3% moderate; and 0% vigorous PA. Light (P = 0.05), vigorous (P = 0.02), and moderate-vigorous PA (MET-minutes; P = 0.02), decreased with a trend in increased SB (P = 0.07). Activity of other intensities and sleep duration did not significantly change. Only 39% and 37% of participants slept between 7–9 hours/night at week 18 and 35, respectively. Forty-six percent (n = 21) and 28% (n = 13) of participants met prenatal PA guidelines during the 2nd and 3rd trimester, respectively. At week 18, no differences in total sleep, SB, or light PA existed for women who met PA guidelines versus those who did not; total PA was significantly greater for women who met guidelines. At week 35, women that met PA guidelines had significantly less SB (P < 0.005) than women who did not. This study demonstrates that pregnant women spend the majority of their day in SB. Significant reductions in total activity across pregnancy may be attributed, in part to shifts in light PA and increased SB. Based on the lifestyle of our sample, regardless of meeting PA guidelines in mid-pregnancy, no significant difference exists in time spent in SB, however meeting PA recommendations in late pregnancy may reduce SB. Future interventions should target reducing SB by increasing light and moderate PA beyond volitional exercise.
