目的了解深圳市流动学龄前儿童贫血患病状况,为制定保护流动儿童健康措施提供参考依据。方法对深圳市部分幼儿园和社区的521名流动学龄前儿童进行营养健康调查,另选500名非流动学龄前儿童作为对照,检测两组儿童血红蛋白(Hb)含量,并作对比分析。结果521名流动学龄前儿童中贫血者89人,贫血患病率为17.08%,且贫血患病有随年龄增长而显著增加的趋势;以3～5岁年龄组贫血患病率最高,为29.53%。男女童贫血患病率基本一致。而非流动学龄前儿童贫血患病率为6.2%,与流动学龄前儿童比较,差异有统计学意义(χ2=32.23,P<0.01).结论流动学龄前儿童贫血患病率高于非流动儿童。应采取相应干预措施,降低流动学龄前儿童的贫血患病率。
Objective To understand the prevalence of anemia in mobile preschool children in Shenzhen and to provide a reference for the development of measures to protect the health of migrant children.
