Abstract

Objective: The objective was to study the relationship between a decrease in gross fetal movement during maternal night sleep counted by an objective method and abnormal perinatal outcomes.

Methods: This was a prospective cohort study. A total of 470 pregnant women recorded fetal movement with the fetal movement acceleration measurement recorder weekly after 28 weeks. The ratio of 10-s epochs with fetal movement to all epochs was calculated as the fetal movement parameter. When the parameter was below the 10th percentile of the previously made reference curve, it was defined as decreased movement. Women who showed a decreased movement at least once were classified into a study group, and the other women were classified into a control group. Abnormal perinatal outcomes between the two groups were compared with the Chi-square test.

Results: There were more preterm births (19%) in the study group than in the control group (10%) (P = 0.0210). There was a significant difference for iatrogenic preterm birth (P = 0.0241) but not for spontaneous preterm birth (P = 0.4566). There were more hypertensive disorders of pregnancy (11.6%), small-for-gestational-age newborns (10.7%), and Apgar scores below 7 points at 1 min (7.4%) in the study group than in the control group (5.2%, 4.8%, and 2.6%, respectively) (P = 0.0329, 0.0459, and 0.0487, respectively).

Conclusion: A decrease in gross fetal movement during maternal night sleep was related to iatrogenic preterm births, small-for-gestational-age newborns, hypertensive disorders of pregnancy, and low Apgar scores at 1 min.

目的目的是研究用客观方法计算的产妇夜间睡眠时胎动减少与围产期异常结果之间的关系:这是一项前瞻性队列研究。共有 470 名孕妇在 28 周后每周使用胎动加速度测量记录仪记录胎动。有胎动的 10 秒钟时间与所有时间的比值被计算为胎动参数。当该参数低于先前绘制的参考曲线的第 10 百分位数时,就被定义为胎动减少。至少出现过一次胎动减少的妇女被划分为研究组,其他妇女被划分为对照组。两组围产期异常结果的比较采用卡方检验:研究组的早产率(19%)高于对照组(10%)(P = 0.0210)。在先天性早产方面有明显差异(P = 0.0241),但在自发性早产方面没有明显差异(P = 0.4566)。与对照组(分别为 5.2%、4.8% 和 2.6%)相比(P = 0.0329、0.0459 和 0.0487),研究组的妊娠高血压疾病(11.6%)、小于妊娠年龄新生儿(10.7%)和 1 分钟 Apgar 评分低于 7 分的新生儿(7.4%)更多:结论:孕产妇夜间睡眠时胎动减少与先天性早产、小于妊娠年龄新生儿、妊娠期高血压疾病和 1 分钟内低阿普加评分有关。
