PLoS One:孕早期缺乏维生素D不会增加不良妊娠结局风险

2015-04-22 MedSci MedSci原创

孕期缺乏维生素D会对妊娠造成何种影响现在仍不明确,但有研究表明,其与妊娠有着藕断丝连的关系。因此Flood-Nichols SK等人进行了一项回顾性队列研究孕早期缺乏维生素D 与接下来的临床结局间的关系。该研究纳入310名健康的单胎妊娠初产妇,收集其血样测定维生素D含量,并记录其妊娠结局。根据孕妇维生素D含量对研究对象进行分层,不良妊娠结局主要为:子痫前期、早产、胎儿生长受限、妊娠期糖尿病、自发性

孕期缺乏维生素D会对妊娠造成何种影响现在仍不明确,但有研究表明,其与妊娠有着藕断丝连的关系。因此Flood-Nichols SK等人进行了一项回顾性队列研究孕早期缺乏维生素D 与接下来的临床结局间的关系。

该研究纳入310名健康的单胎妊娠初产妇,收集其血样测定维生素D含量,并记录其妊娠结局。根据孕妇维生素D含量对研究对象进行分层,不良妊娠结局主要为:子痫前期、早产、胎儿生长受限、妊娠期糖尿病、自发性流产。通过Logistic回归对不良妊娠结局和维生素D含量间相关性进行分析。

该研究共获得了235名孕妇(18-40岁,平均年龄24.3岁)的孕早期维生素D含量,纳入人群中70%的孕妇缺乏维生素D,低于30 ng/mL。总体维生素D含量波动在13-71.6 ng/mL,人群平均含量为27.6 ng/mL。对年龄、种族、BMI、吸烟史、年份等因素进行校正后,研究结果显示,孕早期缺乏维生素D不会增加妊娠不良结局(子痫前期、早产、胎儿生长受限、妊娠期糖尿病、自发性流产)的风险,两者之间没有相关性:aOR=1.01,95% CI 0.961-1.057,P= 0.738。

Flood-Nichols SK等人的研究结果表明,孕早期缺乏维生素D不会导致不良妊娠结局风险增加,两者间无明显相关性。但是数据也表明,很大一部分育龄期女性缺乏维生素D。
