大庆地区儿童维生素A与铁营养状况的相关性研究

Correlation analysis of vitamin A and iron status in children of Daqing

目的了解大庆市儿童维生素A(VA)和铁营养状况之间的关系。方法对大庆市400名3～12岁儿童血浆VA和铁营养状况进行评价,并对其相关性进行分析。结果受试儿童VA平均含量为(1.03±0.20)μmol/L,其中7.8%患VA缺乏,40.5%儿童VA边缘缺乏。血浆VA与Hb呈正相关(r=0.13226,P<0.05),与sTfR呈负相关(r=-0.12681,P<0.05),与TIBC、SF不相关。结论铁缺乏伴随VA边缘缺乏在我市儿童中普遍存在,VA与铁营养状况存在相关性。

Objective：To study the correlation of VA and iron status of Chinese children.Methods：400 children were randomly chosen from children participanting in physical examinations of our hospital.The plasma vitamin A and iron status indexes were detected.The prevalence of VA deficiency and marginal deficiency was assessed and the correlation of VA and iron indexes was studied.Results：The VA concentration of subjects was（1.03±0.20）μmol/L.The prevalence of VA deficiency and VA marginal deficient was 7.8%,40.5% respectively.Plasma VA was positively correlated with Hb（r=0.13226,P0.05） and negatively correlated with sTfR（r=-0.12681,P0.05） significantly but there was no association of SF and TIBC.Conclusion：Iron deficiency coexisted VA marginal deficiency are still very prevalent in Daqing children,plasma VA are correlated with iron status.
