1994年4月在本市前山地区对2293名0～6岁儿童进行了营养性贫血和HBsAg携带状况的调查.结果表明:贫血患病率为14.6％,其中0～2岁组儿童患病率17.6％;3～6岁组儿童患病率13.5％,差异有显著性(P<0.05).由此可见儿童营养性贫血的防治重点应放在婴幼儿期.因该阶段小儿正处在迅速生长发育期,铁需要量明显增加。而婴儿离开母体3～4个月后先天性储铁已经耗尽。如得不到有效的补充,很易引起营养性贫血发生. A total of 2293 children aged 0-6 years were investigated for nutritional anemia and HBsAg carriage in Qianqian in April 1994. The results showed that the prevalence of anemia was 14.6%, of which the prevalence of children aged 0-2 years 17.6%; children aged 3 to 6 years prevalence rate of 13.5%, the difference was significant (P <0.05) .Therefore, children with nutritional anemia prevention and treatment should focus on infants and young children.Because this stage of children are in rapid Growth and development, iron demand increased significantly. The baby after leaving the mother 3 to 4 months after congenital storage of iron has been depleted. Without effective supplement, it is easy to cause nutritional anemia.
