目的:研究妊娠期补钙和日照对孕妇血清25-羟基总维生素D(25-OH-D)水平及产妇和新生儿缺钙症状的影响。方法:将151例正常妊娠期妇女分为不补钙日照不达标组、不补钙日照达标组、补钙日照不达标组、补钙日照达标组4组;采用LIAISON XL化学发光分析仪,进行血清25-OH-D定量检测,并对产妇及胎儿缺钙症状进行随访统计。结果:与不补钙日照不达标组比较,其他3组血清25-OH-D水平均有增高趋势(P<0.05);产妇缺钙率与新生儿缺钙率均有降低趋势(P<0.05)。孕期血清25-OH-D参考值:2.5%百分位数:13.96 ng/ml、中位数:39.54 ng/ml、92.5%百分位数:73.90 ng/ml。所有无症状组血清25-OH-D为(41.67±14.72)ng/ml。结论:孕期适当补充钙及充足日照可预防产妇及新生儿缺钙;孕期血清25-OH-D参考预测值范围区间略小于普通人群。

[Abstract]Objective:To study the effect of supplementation of calcium and sunshine during pregnancy on serum level of total 25-hydroxyvitamin vitamin D(25-OH-D).Methods:A total of 151 cases of normal pregnant women were divided into four groups:without calcium and sunshine,without calcium and with sunshine,with calcium and without sunshine,with calcium and sunshine.LIAISON XL chemiluminescence analyzer was used to detect the serum level of 25-OH-D.Results:Compared with the group of without calcium and sunshine,the serum level of 25-OH-D in other groups increased significantly.The calcium deficiency rate of puerpera and neonatal decreased significantly.The reference range was 13.96 ng/ml(2.5%percentile),39.54 ng/ml(50% percentile)and 73.90 ng/ml(92.5%percentile).The mean value of 25-OH-D was(41.67±14.72)ng/ml.Conclusion:Proper supplementation of calcium and adequate sunshine during pregnancy can prevent calcium deficiency of puerpera and neonate.The reference range of serum 25-OH-D is slightly lower than that in general population.

维生素D(VD)是人类不可缺少的脂溶性维生素,主要作用是增加肠钙吸收,调节骨细胞的功能,影响骨代谢,对维持骨骼健康有重要作用[1]。由于胎儿体内VD与孕妇VD密切相关,孕妇VD是胎儿和新生儿体内VD主要来源,孕妇VD缺乏除对孕妇产生影响外,还可能导致胎儿宫内生长迟缓、婴幼儿及儿童骨矿物质含量减少、肌肉无力和佝偻病等严重的不良后果[2]。……
