妊娠期妇女核黄素营养水平与缺铁性贫血关系的研究

目的：　研究机体核黄素水平与孕妇铁营养状况及缺铁性贫血的关系。方法：　对３２２ 名孕中期妇女进行铁及核黄素营养状况的横断面调查，并从中随机抽取５８ 名进行１２ 周的追踪观察。结果：　核黄素缺乏率在孕中、晚期的妇女分别为２９．８０％ 和６５．５２％ ；贫血患病率分别为３２．７６％ 和４８．２７％ ；储存铁缺乏率分别为５６．９０％ 及８４．４８％ 。核黄素缺乏者的贫血患病率为３６．６０％ ，明显高于核黄素正常者的２１．４０％ （Ｐ＜ ０．０１）；储存铁缺乏率在核黄素缺乏者为４４．０９％ ，也明显高于核黄素正常者的３０．１３％ （Ｐ＜ ０．０５）。相关分析发现，孕晚期ＢＧＲＡＣ与Ｈｂ、ＳＦ、ＳＩ分别呈显著负相关（γＨｂ＝ － ０．２７２９，γＳＦ＝ － ０．２２８３，γＳＩ＝ － ０．１９９７，Ｐ＜ ０．０１），ＢＧＲＡＣ与ＥＦＰ呈显著正相关（ΓＥＦＰ＝ ０．１９６３，Ｐ＜ ０．０１）。结论：　核黄素缺乏与孕妇贫血及缺铁之间呈显著相关。

THE RELATIONSHIP BETWEEN RIBOFLAVIN STATUS AND ANEMIA IN PREGNANT WOMEN

and Methods:The riboflavin and iron status were investigated among 322 in the 2nd trimester and 58 in the 3nd trimesters pregnant women. Results:The incidences of riboflavin (Vit B 2) deficiency, anemia, and iron deficiency were 29.80% and 65.52%, 32.76% and 48.27%, 56.90% and 84.48% in the 2nd and 3nd trimesters pregnancies, respectively. The rate of anemia and iron deficiency were 36.60% and 44.09% in vit B 2 def. pregnancies respectively, while 21.40% and 30.13% in vit B 2 normal pregnancies (P<0.01, P<0.05). There were significant negative correlations between BGRAC and Hb; BGRAC and SF, BGRAC and SI, and positive correlation between BGRAC and EFP. Conclusion:That riboflavin status might be related to anemia and iron deficiency in the investigated pregnant women.
