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 understand the relationship between vitamin A (VA) and iron nutrition in children in Daqing. Methods The plasma VA and iron nutritional status of 400 children aged 3 to 12 years in Daqing city were evaluated and their correlations were analyzed. Results The average content of VA in the children was (1.03 ± 0.20) μmol / L, 7.8% of them were VA deficient and 40.5% of children were lacking in VA margin. Plasma VA was positively correlated with Hb (r = 0.13226, P <0.05), negatively correlated with sTfR (r = -0.12681, P <0.05), but not with TIBC and SF. Conclusion The lack of VA with VA deficiency is common in children in our city. There is a correlation between VA and iron nutrition status.
