目的描述使用加速度计客观测量的妊娠中晚期体力活动（PA）的特征。方法采用日本TDK公司生产的Silmee W10型加速度计连续7天测量孕中期和孕晚期孕妇的PA。结果共检查34例经产妇女。在怀孕的第二和第三个三个月期间，PA的量没有统计学上的显著差异。亚组分析表明，全职家庭主妇组的PA显着增加，从第二至第三个三个月，而总PA和中度和剧烈PA的停止工作组，在这段时间内显着下降。目前工作组的PA在妊娠期之间没有差异。在全职家庭主妇组，每小时的PA量显着增加，在12：00，18：00，22：00小时。在目前的工作组，每小时的PA量显着增加，在9：00，10：00，16：00小时。在停止工作组，每小时的PA量显着减少，在7：00，8：00，18：00小时。结论使用加速度计的客观测量没有发现任何显着变化，PA在不同孕期。亚组分析显示，PA变化与怀孕期间不同的生活方式相关的明确模式。未来的研究可能会通过确定PA和妊娠结局之间的关系来开发个性化的健康指导。
Aim To describe the characteristics of objectively measured physical activity (PA) during the 2nd and 3rd trimesters of pregnancy using a accelerometer. Methods This was a longitudinal observational study wherein PA in pregnant women in the 2nd and 3rd trimesters was measured for seven consecutive days using a accelerometer (Silmee W10, TDK, Japan). Results A total of 34 primiparous women were examined. There was no statistically significant difference in the amount of PA during the 2nd and 3rd trimesters of pregnancy. Sub-group analysis demonstrated that PA in the full-time housewife group increased significantly from the 2nd to the 3rd trimester, while total PA and moderate and vigorous PA of the stopped-working group, decreased significantly over that time. There was no difference in the PA of the currently working group between trimesters. In the full-time housewife group, the amount of PA for each hour significantly increased at 12:00, 18:00, and 22:00 hr. In the currently working group, the amount of PA for each hour significantly increased at 9:00, 10:00, and 16:00 hr. In the stopped-working group, the amount of PA for each hour significantly decreased at 7:00, 8:00, and 18:00 hr. Conclusion Objective measurements using an accelerometer did not identify any significant changes in PA during the different trimesters of pregnancy. Sub-group analysis revealed clear patterns in PA change correlating with different lifestyles during pregnancy. Future research may enable the development of personalized health guidance by identifying the relationship between PA and pregnancy outcomes.
