Mol Autism:孕期使用叶酸补充剂与儿童孤独症谱系障碍风险之间的关系

2019-09-16 不详 网络

既往研究评估了孕期使用叶酸补充剂与儿童孤独症谱系障碍(ASD)风险之间的关系,但没有明确的结论。因此,我们进行了更全面的荟萃分析,以重新评估叶酸与ASD风险之间的关系。研究检索了PubMed,Web of Knowledge和Wanfang Data电子数据库进行了仔细搜索,纳入2017年3月新近发表的符合条件的研究。使用随机效应模型将相对风险(RR)与95%置信区间(CI)相结合。进行了敏感性分

既往研究评估了孕期使用叶酸补充剂与儿童孤独症谱系障碍(ASD)风险之间的关系,但没有明确的结论。因此,我们进行了更全面的荟萃分析,以重新评估叶酸与ASD风险之间的关系。

研究检索了PubMed,Web of Knowledge和Wanfang Data电子数据库进行了仔细搜索,纳入2017年3月新近发表的符合条件的研究。使用随机效应模型将相对风险(RR)与95%置信区间(CI)相结合。进行了敏感性分析,并评估发表文章的偏倚。

本报告共纳入12篇文章,包括16项研究,4514例ASD病例。结果发现,与没有补充叶酸的女性相比,怀孕期间补充叶酸可降低ASD的风险[RR = 0.771,95%CI = 0.641-0.928,I2 = 59.7%,异质性= 0.001]。这些关联在亚洲,欧洲和美国人群中具有重要意义。

总之,这项全面的荟萃分析表明,与不补充叶酸的女性相比,孕期使用叶酸补充剂可以显著降低儿童ASD的风险,而无论其种族如何。
