2006～2010年甘肃农村地区0～6岁儿童贫血患病率调查分析

Investigation and analysis on prevalence rate of anemia in 0-6-year-old children from rural area of Gansu province from 2006 to 2010

目的:了解甘肃省农村地区0～6岁儿童贫血患病情况。方法:采用分层随机整群抽样选取甘肃清水、康乐、古浪、陇西0～6岁儿童为调查对象,对其进行血红蛋白含量测定。结果:共检测5 454人,男童贫血患病率8.60%,女童贫血患病率8.26%;2006～2010年不同年份男、女童贫血患病率差异均有统计学意义(P<0.01),但男、女间差异无统计学意义(P>0.05)。随着时间的变迁儿童血红蛋白均值有所提高,不同年龄组儿童贫血患病率差异有统计学意义(P<0.05),5年间儿童贫血高峰均在24月龄以内,最高峰集中在12月龄及以下,随后逐渐降低。结论:甘肃省0～6岁儿童贫血状况不容乐观,重点地区在农村,尤其针对2岁以下儿童加强贫血防治,采取相应干预措施,改善儿童贫血状况。

Objective： To understand the prevalence of anemia in 0-6-year-old children living in rural area of Gansu province.Methods： Stratified random sampling method was used to select 0-6-year-old children from Qingshui county,Kangle county,Gulang county and Longxi county of Gansu province as respondents,and then the contents of hemoglobin were measured.Results： A total of 5 454 children were selected and detected,the prevalence rates of anemia in boys and girls were 8.60% and 8.26%,respectively;there were statistically significant differences in prevalence rates of anemia in boys and girls among different years from 2006 to 2010（P 0.01）,but there was no statistically significant difference between boys and girls（P 0.05）.The average level of hemoglobin in children increased with time,there was statistically significant difference in prevalence rate of anemia among children in different age groups（P 0.05）,the average peak of prevalence rate of anemia in children was found within 24 months,the most peak of prevalence rate of anemia concentrated in 12 months and below,then it decreased gradually.Conclusion： The prevalence of anemia in children under six years in Gansu province is higher,especially in rural area and children under two years old,it is necessary to make corresponding interventional measures to improve the prevalence of anemia in children.
