目的比较孕中、晚期妇女的维生素D营养状况,为不同孕期妇女补充维生素D提供依据。方法选取嘉兴市妇幼保健院2013年4—6月建卡并定期产检的孕妇520人,按初次检测血清25-(OH)D水平时的孕周分成两组,即孕中期278人和孕晚期242人,评估两组孕妇血清25-(OH)D水平及维生素D营养状况。结果孕中、晚期孕妇血清25-(OH)D水平分别为(28.0±10.4)和(37.7±9.8)nmol/L,两者差异有统计学意义(P<0.01)。孕中、晚期妇女存在维生素D营养状况不良分别占99.28%和98.76%,孕中期组妇女营养不良比孕晚期组严重(P<0.01)。结论妊娠中、晚期妇女普遍存在维生素D营养不良,孕中期妇女更为严重,应及早干预。
Objective To compare the nutritional status of vitamin D in pregnant women and late women and provide basis for vitamin D supplementation in different pregnant women. METHODS: A total of 520 pregnant women who were scheduled for card-making from April to June in 2013 in Jiaxing Maternal and Child Health Hospital were divided into two groups according to their gestational ages of 25- (OH) D for the first time, that is, 278 pregnant women and the third trimester of pregnancy 242 people, to assess the serum 25- (OH) D levels and vitamin D nutrition status of pregnant women in both groups. Results Serum levels of 25- (OH) D in pregnant women and late pregnant women were (28.0 ± 10.4) and (37.7 ± 9.8) nmol / L, respectively, with statistical significance (P <0.01). The prevalence of malnutrition of vitamin D in pregnant women and advanced women was 99.28% and 98.76%, respectively. The malnutrition of pregnant women in the second trimester was worse than that in the third trimester (P <0.01). Conclusion The prevalence of vitamin D malnutrition in women in the middle and late pregnancy is more serious in the second trimester of pregnancy, and should be intervened as soon as possible.
