【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。
【Objective】 To analyze the prevalence of anemia among infants and young children resident in Beijing from Beijing and provide a basis for health intervention. 【Methods】 A retrospective analysis was conducted on the five categories of peripheral blood or venous blood from 141 to 331 children aged 6 months to 3 years who were admitted to the Children’s Hospital of Capital Institute of Pediatrics from January to December 2011. According to hemoglobin less than 110g / L for anemia screening criteria, MCV and MCHC levels for the type of anemia screening criteria, 6-month-old group (6-12 months), 1-year-old group and 2-year-old group of three age groups Statistical analysis. 【Results】 The total prevalence of anemia in infants and young children was 10.29% in this retrospective analysis. The prevalence of anemia in 6 months to 22 weeks was 8.52% in patients of 1 year old and 1.97% in patients of 2 years old. Chi-square test showed that the difference between the age groups was statistically significant. Analysis of anemia types revealed a small cell hypochromic anemia of 12.43%, a large cell anemia of 0.24%, a positive cell anemia of 17.03% and a simple cell anemia of 69.78%. Analysis of the degree of anemia showed 13,276 mild anemia cases, with a prevalence of 9.39%; 1 247 cases of moderate anemia with a prevalence of 0.88%; and 19 cases of severe anemia with a prevalence of 0.013%. 【Conclusion】 The prevalence of anemia among infants and young children at 6 months of age is the highest, and the prevalence of mild anemia is the highest. The results of this analysis can be used as experimental reference for the intervention of nutrition and health care in outpatient clinic children.
