Abstract: Objective To understand the incidence and risk factors of iron deficiency anemia of 6~8-month-old infants in Beijing,in order to provide data support for further development interventions of infant anemia. Methods A cohort study was conducted,and stratified cluster sampling was used to select newborns having their health care in the community healthcare centers,and then following up the infants till the first blood test.After data cleaning,the single factor and Logistic regression were used to explore the risk factors of iron deficiency anemia. Results A total of 2 243 children were involved in this study,and the incidence of iron deficiency anemia was 19.6%(446/2 243).Logistic regression showed that infants at the age of 6 to 8 months old whose parents' owning agricultural registered permanent residence(OR=1.568,95%CI:1.164~2.112),whose family had more than one child (OR=1.490,95%CI:1.150~1.929),whose father was younger than 25 years old when the child was born (OR=1.660,95%CI:1.119~2.464),whose mother did not use chalybeate before pregnancy (OR=1.440,95%CI:1.071~1.936),who was delivered in the second level hospital (OR=1.465,95%CI:1.112~1.931),who are low birth weight (OR=3.340,95%CI:1.398~7.980),who was a boy (OR=1.285,95%CI:1.025~1.611) and who was breastfed (OR=2.217,95%CI:1.584~3.102) have a higher risk to anemia. Conclusion 1)The incidence of iron deficiency anemia in 6 to 8-month-old infant is high in Beijing.2)The factors influencing the infant iron status and socio-economic factors can lead iron deficiency anemia in infants.

摘要: 目的 了解北京地区6~8月龄婴儿缺铁性贫血发生率以及危险因素,为下一步制定婴儿贫血干预措施提供数据支撑。方法 研究采用队列研究的方法,分层整群抽取项目社区新生儿进行随访,直至其6~8月龄进行血常规检测为止。数据归纳整理后,运用单因素及Logistic回归探讨缺铁性贫血的危险因素。结果 西城区、海淀区和密云区16家项目社区卫生服务中心共2 243名儿童在6~8月龄时进行血色素测定,缺铁性贫血发病率为19.6%(446/2 243)。Logistic回归显示,父母一方或双方是农业户籍(OR=1.568,95%CI:1.164~2.112),家庭孩子数较多(OR=1.490,95%CI:1.150~1.929),出生时父亲年龄≤25岁(OR=1.660, 95%CI:1.119~2.464),母亲孕前未服用铁剂(OR=1.440,95%CI:1.071~1.936),二级机构出生(OR=1.465,95%CI:1.112~1.931),低出生体重(OR=3.340,95%CI:1.398~7.980),性别为男性(OR=1.285,95%CI:1.025~1.611)以及母乳喂养(OR=2.217,95%CI:1.584~3.102)的6~8月龄婴儿发生缺铁性贫血的风险较高。结论 1)北京地区6~8月龄婴儿缺铁性贫血发生率较高。2)影响婴儿铁水平的因素以及社会经济因素均可导致婴儿缺铁性贫血的发生。
