目的分析中国贫困地区2～5岁儿童的贫血患病情况及与喂养行为相关的影响因素。方法采用多阶段整群随机抽样的方法,在贫困地区13个省(自治区、直辖市)30个县(市)随机抽取5927名2～5岁儿童进行调查,调查内容包括儿童的一般情况、喂养状况和检测血红蛋白值。结果我国贫困地区2～5岁儿童的贫血患病率为22.4%,男童与女童无明显差异。多因素非条件Logistic分析结果显示:断奶时间、是否吃早餐、家里就餐人数、母亲文化程度、孩子在家就餐次数及家庭人均年收入等均与儿童的贫血患病状况有较大的相关。结论我国贫困地区2～5岁儿童的贫血状况依然严重,且与家庭喂养条件及喂养行为有密切关系。需有针对性的开展贫血的预防与干预。
