摘　　要：目的 探究河南省贫困地区婴幼儿服用营养包的潜在类别,并分析该潜在类别与贫血的关联性。方法 通过多阶段随机抽样方式,于2018年6-9月纳入4433名6-24月龄婴幼儿。测量婴幼儿血红蛋白并对看护人进行问卷调查,使用潜类别分析对婴幼儿营养包服用进行分类,使用两水平Logistic回归探究营养包服用与贫血的关联性。结果 (1)2018年河南省贫困地区6-24月龄婴幼儿贫血率15.1%。(2)婴幼儿营养包服用特点存在2个潜在类别:有效服用,潜在类别概率0.889;非有效服用,潜在类别概率0.111。(3)与有效服用相比,未服用(OR=1.365,P<0.001)及非有效服用营养包(OR=1.265,P=0.034)的婴幼儿贫血风险均升高。结论 开展贫困地区儿童营养改善项目可以有效降低河南省婴幼儿贫血率,有效服用是保证营养包贫血干预效果的关键。OBJECTIVE To explore latent classes of Yingyangbao(YYB) consumption among infants and young children in impoverished areas of Henan Province, and to analyze the relationship between these classes and anemia status.METHODS We recruited 4433 children aged 6 to 24 months by multi-stage random sampling in 14 poverty-stricken counties of Henan Province between June and September 2018. We conducted hemoglobin concentration measurement among children and questionnaire survey among their caregivers. Then we used latent class analysis to classify the characteristics of YYB consumption among the children and two-level Logistic regression was used to explore relationship between YYB consumption and anemia status.RESULTS The prevalence of anemia was 15.1% in poor areas of Henan Province in 2018. There were two latent classes of YYB consumption among children: the one was “effective consumption”, latent class probability was 0.889;the other called “ineffective consumption”, latent class probability was 0.111. Compared with effective consumption, children who never have consumed YYB(odds ratio(OR)=1.365, P<0.001) or were in “ineffective consumption” class(OR=1.265, P=0.034) were both positive related to anemia.CONCLUSION Prevalence of anemia among children in impoverished areas has been significantly reduced since the launch of Program of Children’s Nutrition Improvement in Impoverished Areas. Effective consumption is a key to ensuring YYB’s anemia intervention effect.
