【目的】 了解维生素A(VA)缺乏和贫血之间的关系。 【方法】 全国分层抽取 14个省 42个市县的8699名 6岁以下儿童 ,血清维生素A和血红蛋白的测量 ,分别采用荧光法及HemocueSystem血红蛋白测定仪。 【结果】 血红蛋白正常、轻度、中度和重度贫血组儿童VA缺乏率分别为 10 .8%,18.7%,2 3 .2 %,42 .9%,随血红蛋白水平下降显著增加。VA正常、VA可疑缺乏及VA缺乏组儿童贫血患病率分别为 6.1%,12 .7%,17.1%。随血清VA水平下降不仅贫血患病率增加 ,而且贫血严重度增加。 【结论】 VA和铁之间可能存在着相互影响
【Objective】 To understand the relationship between vitamin A (VA) deficiency and anemia. 【Method】 8699 children under 6 years old in 42 cities and counties of 14 provinces and 42 cities were stratified stratified to measure serum vitamin A and hemoglobin by fluorescence method and HemocueSystem hemoglobin analyzer respectively. 【Results】 The VA deficiency rate in children with normal hemoglobin, mild, moderate and severe anemia was 10.8%, 18.7%, 23.2% and 42.9%, respectively, with a significant increase as hemoglobin level decreased. The prevalence of anemia in normal VA, suspicious VA and VA-deficient children were 6.1%, 12.7% and 17.1% respectively. With the decline of serum VA level not only the prevalence of anemia increased, and the severity of anemia increased. 【Conclusion】 There may be interaction between VA and iron
