目的 了解6月龄儿童贫血发生与喂养方式及辅食添加的关系,为制定保健策略提供依据。方法 整群抽取闵行区常规儿童保健中年满6个月有血红蛋白记录的正常足月出生儿童10 617人,对其喂养方式、辅食添加种类、两次保健期间的患病情况,体格发育情况进行回顾分析。结果 无添加辅食儿童的贫血发生率高于已添加辅食儿童,其三组喂养方式间的贫血发生未见差异。辅食添加类别数为1项的儿童患贫血风险是辅食添加类别数为2项及以上的1.5倍。男性、非本市户籍、出生体重＜2 500 g或≥4 000 g、无辅食添加、无蛋黄摄入是贫血发生危险因素。结论 今后应加强相关知识的宣传,提高家长的营养知识、喂养态度和喂养技术,对有贫血发生危险因素的儿童及时添加多样性的辅食,以降低6月龄儿童患贫血的风险。

Results The prevalence rate among the infants without complementary food consumed was higher,and there were no significant differences between the infant groups with different feeding patterns.Odd ratio of complementary food consumed more than 2 types group towards infant anemia was 50% higher than the only one type group.Baby boy,baby of nonlocal household register,birth weight lower than 2 500g or higher than 4 000g,without egg yolk consumed,without any complementary food consumed were the risk factors of infant anemia.
