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。
Objective To understand the prevalence of iron, vitamin A, riboflavin and other nutrients in pregnant women and the prevalence of anemia in order to provide a scientific basis for nutrition intervention. Methods A total of 430 anemic pregnant women and 292 non-anemic pregnant women were randomly selected from Xinxian County, Shandong Province. The 24-h retrospective study was conducted to compare the intake of main nutrients in pregnant women with vitamin A, riboflavin and iron in pregnant women. Results The dietary intake of the two groups of pregnant women was mainly cereal foods such as cereals. The intake of iron was close to the recommended dietary intakes (RNIs). The results of serum test showed that the levels of iron nutrition in anemia group were significantly lower than those in non-anemia group Plasma ferritin was <14μg / L in pregnant women with a% anemia and average of transferrin receptor was 31.42nmol / L in the anemia group. The ratio of vitamin A and riboflavin deficiency in the anemia group was 62.9% and 63.1% respectively, which was significantly higher than that in the corresponding non-anemia group (P <0.01). Conclusions Anemia is not only related to the absorption and utilization rate of iron, but also closely related to inadequate or deficient intake of vitamin A and riboflavin.
