【摘要】 目的了解维生素A(VitA)缺乏和贫血之间的关系。方法采取整群分层抽样抽取福建省9个地市3 178名5岁以下儿童,并检测VitA和血红蛋白的含量。结果血红蛋白正常、100~110 g/L、90~100 g/L、<90 g/L四组不同血红蛋白值儿童VitA缺乏率分别为6.19%、5.58%、8.29%和9.8%,随血红蛋白水平下降显著增加。VitA正常、VitA可疑缺乏及VitA缺乏组儿童贫血患病率分别为5.79%、10.26%、9.5%。随着血清VitA水平下降,不仅贫血患病率增加,而且贫血严重度也增加。结论亚临床VitA缺乏在儿童中已是很重要的营养问题,并与贫血有一定关系。更多还原

【Abstract】 Objective To explore the relationship between deficiency of vitamin A(VAD)and anemia.Methods 3 178 children under 5 years in 9 cities of Fujian province were stratified-randomly sampled and surveied.Levels of serum vitamin A and hemoglobin(Hb)were examined.Results Prevalence rate of vitamin A deficiency in Hb normal group、Hb 100～110 g/L、90～100 g/L、<90 g/L groups were 6.19%,5.18%,8.29%,9.8%,respectively,rising with the decrease of hemoglobin level.Prevalence rate of anemia in groups of children with normal,suspicious VAD and confirmed VAD were 5.29%,10.26%,9.5% respectively.Both prevalence rates and severity grade of animia increased with the decrease of serum vitamin A level.Conclusion Subclinical VAD in children has been a serious nutrional problem,which is often related to anemia.更多还原
