Abstract: 【Objective】 To analyze the anemia status among infants and young children in out-patient department of hospital from Beijing area resident population. 【Methods】 A retrospective analysis of January to December 2011 in our hospital,141 331 cases of 6 months~3 years old in children with peripheral blood or blood routine test results of five classification.In accordance with the hemoglobin of less than 110 g/L for anemia screening criteria,MCV and MCHC level differences were screening criteria of anemia type.The population were divided into 6 months age group,1 age group and 2 age group and statistically analyzed. 【Results】 The results showed that total anemia prevalence rate was 10.29% from the survey population in infants and young children,in which iron-deficiency anemia was accounted for 12.43%,macrocytic anemia accounted for 0.24%,normocytic anemia accounting for 17.03% and Simple microcytic anemia accounting for 69.78%.Anemia prevalence rate of 6 months of age (from 6~12 months) group was 22.1%,1 age group was 8.52% as well as 2 age group was 1.97%,respectively.The prevalence of anemia was 9.39% in mild anemia of 13 276 patients,the prevalence of anemia was 0.88% in moderate anemia of 1 247 patients;severe anemia was found in 19 cases. 【Conclusion】 The prevalence of anemia among children with 6 month old group was the highest prevalence of anemia.Mild anemia prevalence ranks first.The result of the statistical analysis data would be provided as much help as infants and young children nutrition and health intervention experiment basis in out-patient department.

摘要： 【目的】 对来院就诊北京地区常住人口婴幼儿贫血患病情况进行统计分析,为保健干预提供依据。 【方法】 回顾分析2011年1-12月来首都儿科研究所附属儿童医院就诊141 331例6月龄~3岁儿童末梢血或静脉血血常规五分类检测结果。按照血红蛋白低于110g/L为贫血筛查标准,MCV和MCHC水平差异为贫血类型筛选标准,6月龄组(6~12月龄)、1~岁组和 2~岁组共3个年龄组进行统计学分析。 【结果】 本次回顾分析人群中,婴幼儿贫血总患病率为10.29%,6月龄~组贫血患病率为22.1%,1~岁组为8.52%,2~岁组为1.97%,χ²检验结果表明年龄组间患病率差异有统计学意义。贫血类型分析发现小细胞低色素贫血为12.43%,大细胞性贫血为0.24%,正细胞性贫血为17.03%以及单纯小细胞性贫血为69.78%。贫血程度情况分析表明轻度贫血13 276例,患病率为9.39%;中度贫血1 247例,患病率为0.88%;重度贫血19例,患病率为0.013%。 【结论】 以婴幼儿6月龄组贫血患病率最高,轻度贫血患病率居首位,本次资料分析结果可作为现阶段门诊就诊儿童人群营养保健干预的实验参考依据。
