摘要: 目的 根据项目地区儿童血红蛋白的测量结果,了解西藏自治区农村地区3岁以下儿童的贫血状况,筛选相关因素进行分析并制定干预措施。方法 采用人口比例抽样方法,对西藏自治区4个地区、15个项目县70个乡的1 513名3岁以下儿童及母亲进行调查和血红蛋白测定。结果 西藏自治区农村项目地区3岁以下儿童贫血患病率为37.8%,儿童贫血随月龄变化,12～24月龄是3岁以下儿童贫血患病率的高峰,以后贫血率随月龄增加而下降。在海拔4 500 m以上,儿童贫血患病率达到52.5%。不同地区、不同性别贫血患病率不同,男童贫血患病率明显高于女童,差异有统计学意义(P<0.01)。母亲贫血与儿童贫血关系密切,母亲贫血的儿童贫血患病危险度是母亲不贫血的儿童贫血患病的2.005倍。多因素Logistic回归分析显示,儿童性别、母亲贫血、生长迟缓和海拔高度与儿童贫血有统计学联系。结论 西藏农村地区3岁以下儿童贫血状况不容乐观。Abstract: Objective To analyze the anemia status of children under 3 years old in rural Tibet of China.Methods Using PPS sampling method to investigate 1513 children under three years old in 4 regions,15 counties and 72 townships.Results The prevalence of anemia among the children was 37.8%.Prevalence of anemia was varying along with ages.The peak of anemia prevalence was at 12~24 months.And it decreased with the increasing of age.The prevalence of anemia was 52.5% above the height of 4 500 meters.Different gender and regions had different prevalence of anemia.The prevalence rate of the boys was higher than that of the girls(P<0.01).The related risk of anemia for the child with anemia mother was 2.005.The analysis of logistic regression showed that children's gender,mother anemia,stunting and differentheig hthad the significant relations to child anemia.Conclusion The feasible measures should beset down to decrease the prevalence of anemia.
