摘要 目的调查潍坊地区孕期女性的叶酸利用能力,分析叶酸利用能力与不良孕产史的相关性,为围受孕期叶酸补充和风险监测提供指导。方法对2 934例潍坊地区孕期女性进行叶酸利用能力遗传检测,采用Taqman-MGB技术检测亚甲基四氢叶酸还原酶(MTHFR)基因C677T、A1298C和甲硫氨酸合成酶还原酶(MTRR)基因A66G位点的单核苷酸多态性分型,对叶酸利用能力遗传风险进行分级。结果潍坊地区孕期女性发现高度叶酸利用能力遗传风险的比例为40.05%,全国参考数据为19.70%,P<0.01;未发现遗传风险的比例为26.48%,全国参考数据为33.04%%,P<0.01。正常孕产组和不良孕产组的叶酸利用能力总体构成不同,存在统计学差异(χ2=19.47,P<0.01),正常孕产组未发现遗传风险人群的比例为28.29%,不良孕产组为14.40%,两组比较P<0.05;正常孕产组高度遗传风险人群的比例为38.13%,不良孕产组为52.88%,两组比较P<0.01。结论潍坊地区孕期女性叶酸利用能力较全国人群偏低;叶酸代谢和利用障碍与不良孕产史有相关性。
