贫血孕妇铁与维生素A营养状况分析

Investigation on nutritional status of iron and retinal in anemic pregnant women

摘要

摘要:
目的了解妊娠妇女铁、维生素A、核黄素等营养素的摄入及贫血的患病情况, 为开展营养干预提供科学依据。
方法随机抽取山东省莘县430名贫血孕妇和292名非贫血孕妇, 采用24 h回顾法比较2组孕妇主要营养素摄入情况, 分析孕妇维生素A、核黄素及铁的营养水平。
结果 2组孕妇膳食均以粮谷类等植物性食物为主, 铁的摄入量接近膳食推荐摄入量(RNIs); 血清检验结果显示, 贫血组的铁营养水平明显低于非贫血组; 85.2%贫血孕妇血浆铁蛋白 < 14μg/L, 转铁蛋白受体平均为31.42 nmol/L; 贫血组缺乏维生素A和核黄素的比例分别为62.9%和63.1%, 明显高于相应的非贫血组(P < 0.01)。
结论贫血不仅与铁的吸收利用率有关, 而且与维生素A、核黄素摄入不足或缺乏有密切关系。

Abstract:
Objective To investigate the nutritional status of iron, vitamin A and riboflavin in anemic pregnant women.
Methods 430 anemic pregnant women and 292 nonanemic pregnant women were randomly recruited from Shenxian country, China.The daily intake of dietary nutrients was collected by the 24 h-diet recall.The levels of serum ferritin, soluble transferrin receptor, riboflavin and retinal were determined.
Results The vegetable foods accounted for a high percentage both in anemic and nonanemic pregnant women.The average daily intake of iron was near to its RNI; the level of serumiron in anemia group was remarkably lower than that of the nonanemia group.About 85% of anemic pregnant women were less than 14 Lg/L of plasma ferritin and the averagely 31.42 nmol/L of sTfR.The percentages of riboflavin and retinol deficiency were 62.90% and 63.09% in anemic pregnant women, respectively, which were much higher than that of the nonanemic group(P < 0.01).
Conclusion The anemia of pregnant women might be related to the iron poor bioavailability, and the deficiencies of retinal, riboflavin.
