BACKGROUND
Recent studies have shown that consumption of date fruits during pregnancy and also postpartum period might affect some pregnancy outcomes. We performed an updated systematic review and meta-analysis about the effects of consuming date fruits on gestation, labor, and delivery.
METHODS
Two researchers independently searched the online databases of PubMed, Scopus, Web of Science, Embase, Google Scholar, and EBSCO up to January 2019 for clinical trials examining the effects of date fruits consumption on any types of gestation, labor, and delivery outcomes. A fixed-effects model or random-effects models were applied to pool data, where appropriate. Quality assessment was done by Jadad scale.
RESULTS
In total, 11 and 8 studies were included in the systematic review and meta-analysis. Meta-analysis revealed that date fruit consumption significantly reduced gestation duration (pooled effect size: -0.30, 95% CI: -0.45, -0.15; P < 0.001), increased cervical dilation on admission (pooled effect size: 0.94, 95% CI: 0.88, 1.00; P < 0.001), and shorten duration of first stage of labor (pooled effect size: -50.09, 95% CI: -72.25, -27.93; P < 0.001). Also, it was revealed that date fruit consumption significantly reduced duration of second stage of labor in fixed-effects model (pooled effect size: -9.85, 95% CI: -14.00, -5.70; P < 0.001); however, this effect was not significant in random-effects analysis (pooled effect size: -11.27, 95% CI: -28.23, -5.68; P = 0.193).
CONCLUSIONS
Date fruits intake seems to reduce gestation duration and duration of the first stage of labor, and also increase cervical dilation on admission.
背景
最近的研究表明，怀孕期间和产后食用枣椰果可能会影响某些妊娠结局。我们进行了一项更新的系统评价和荟萃分析，以了解食用枣椰果对妊娠、分娩和分娩的影响。
方法
两名研究人员独立检索了 PubMed、Scopus、Web of Science、Embase、Google Scholar 和 EBSCO 在线数据库，以查找截至 2019 年 1 月检查枣椰果消费对任何类型妊娠、分娩和分娩结局影响的临床试验。在适当的情况下，应用固定效应模型或随机效应模型对数据进行汇总。通过 Jadad 量表进行质量评估。
结果
共有 11 项和 8 项研究被纳入系统评价和荟萃分析。荟萃分析显示，枣椰果的消费显著缩短了妊娠时间（汇总效应大小：-0.30，95%置信区间：-0.45，-0.15；P<0.001），增加了入院时宫颈扩张（汇总效应大小：0.94，95%置信区间：0.88，1.00；P<0.001），并缩短了第一产程的持续时间（汇总效应大小：-50.09，95%置信区间：-72.25，-27.93；P<0.001）。此外，研究结果还表明，在固定效应模型中，枣椰果的消费显著缩短了第二产程的持续时间（汇总效应大小：-9.85，95%置信区间：-14.00，-5.70；P<0.001）；然而，在随机效应分析中，这种效果并不显著（汇总效应大小：-11.27，95%置信区间：-28.23，-5.68；P=0.193）。
结论
枣椰果的摄入似乎可以缩短妊娠时间和第一产程的持续时间，同时增加入院时宫颈扩张的程度。
