JCEM:使用含雌激素避孕药可增加25(OH)D的浓度

2016-08-07 MedSci MedSci原创

既往小型研究已经表明外源性雌激素可能改善维生素D的水平,但是其机制并不清楚,因为使用激素的女性其选择的生活方式可能会影响维生素D的状态。本研究旨在探究激素避孕与25羟基维生素D(25(OH)D)之间的关联。 采用横截面数据的线性回归模型来评估校正其他混杂因素后,季节调整后的血清25(OH)D与雌激素使用之间的关联。 研究共纳入了1662名参与子宫肌瘤队列研究的非裔美国妇女,年龄在23

既往小型研究已经表明外源性雌激素可能改善维生素D的水平,但是其机制并不清楚,因为使用激素的女性其选择的生活方式可能会影响维生素D的状态。本研究旨在探究激素避孕与25羟基维生素D(25(OH)D)之间的关联。

采用横截面数据的线性回归模型来评估校正其他混杂因素后,季节调整后的血清25(OH)D与雌激素使用之间的关联。

研究共纳入了1662名参与子宫肌瘤队列研究的非裔美国妇女,年龄在23 - 34岁,收集每名参与者血液样本,测量拟人化的变量和皮肤反射,并完成关于人口统计学特征、饮食和膳食补充剂的摄入、避孕、生育史和医疗史以及行为。

结果发现,血清25(OH)D的浓度较低(70%的研究对象,< 20纳克/毫升)。目前使用的含雌激素避孕药与校正后25(OH)D 的浓度增加20%有关(95%的CI:14 - 27)。对于过去曾使用雌激素的参与者,并没有发现其25(OH)D的浓度增加,而当前使用雌激素的参与者却有所增加,表明这个结果未受未测量与避孕选择相关的混杂因素的影响。

总而言之,使用含雌激素避孕药可增加25(OH)D的浓度为涉及的生物途径提出了机制方面的问题,并强调有必要行进一步的研究以探究内源性雌激素对维生素D的影响。
