目的 了解深圳市托幼机构儿童贫血现状,为降低儿童贫血患病率,制定预防策略和干预措施提供理论依据。方法 用分层整群抽样方法,收集随机抽取的317所托幼机构儿童2013年体检资料进行统计分析。结果 1)深圳市托幼机构儿童血红蛋白平均值为(123.83±8.83)g/L。其贫血患病率为6.28%,以轻度贫血为主占98.7%。2~6岁组儿童分别为4.16%、4.59%、3.88%、10.81%、8.50%,不同年龄组间儿童贫血患病率不同(χ2=1 304.4,P<0.001)。男女童贫血患病率无明显差异(χ2=0.143,P=0.705)。2)中心区托幼机构儿童贫血患病率3.83%低于周边区7.51%(χ2=432.63,P<0.001)。3)未评级、区级、市级、省级托幼机构的儿童贫血患病率依次为7.39%、7.23%、4.57%、4.11%,其差异有统计学意义(χ2=284.0,P<0.001),托幼机构级别与贫血患病率呈线性趋势(χ2=246.1,P<0.001)。4)患有低体重、生长迟缓、消瘦、肥胖儿童的贫血患病率均高于正常儿童(P<0.001)。结论 深圳市托幼机构儿童贫血现状不容乐观,需针对不同情况儿童采取干预措施,进一步降低其贫血患病率,促进儿童健康成长。
Abstract
Objective To acknowledge the anemia status of kindergarten children in Shenzhen,provide a theoretical basis to develop prevention strategies and interventions for reducing the prevalence of anemia of children in kindergartens. Method With stratified cluster sampling,317 kindergartens were randomly selected and collected the whole physical examination data in 2013 for statistical analysis. Results 1)The average hemoglobin of kindergarten children in Shenzhen was (123.83±8.83)g/L.The prevalence of anemia was 6.28% and the mild anemia account for 98.7%.The prevalence of 2~6 years old children were 4.16%,4.59%,3.88%,10.81%,8.50% respectively,and the prevalence rate of anemia among children in different age groups was different(χ2=1 304.4,P<0.001).There was no significant difference in the prevalence of anemia between boys and girls(χ2=0.143,P=0.705).2)The prevalence rate of anemia of kindergarten children in center district was 3.83% and lower than 7.51% in the surrounding area (χ2=432.63,P<0.001).3) The prevalence of anemia in unrated,district,municipal,provincial kindergartens followed by 7.39%,7.23%,4.57% and 4.11% ,the difference had statistical significance(χ2=284.0,P<0.001).The level of kindergartens and anemia prevalence rate had linear trend(χ2=284.0,P<0.001).4)The prevalence of anemia in children with low weight,growth retardation,and weight loss was higher than that of normal children (P<0.001). Conclusion Shenzhen kindergarten children's anemia situation is not optimistic,measures according to the different situations of the children should be taken to further reduce the prevalence of anemia,and promote the healthy growth of children.
