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.
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.
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.
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.
探讨河南省贫困地区婴幼儿营养包（YYB）的潜在消费类型，并分析这些类型与贫血状况之间的关系。
2018年6月至9月，我们在河南省14个贫困县通过多阶段随机抽样招募了4433名6至24个月的儿童。我们对儿童进行了血红蛋白浓度测量，并对其照顾者进行了问卷调查。然后，我们使用潜在类别分析对儿童营养包的消费特征进行分类，并使用二级逻辑回归来探讨营养包消费与贫血状况之间的关系。
2018年河南省贫困地区贫血患病率为15.1%。儿童营养包消费存在两种潜在类型：一种是“有效消费”，潜在类别概率为0.889；另一种是“无效消费”，潜在类别概率为0.111。与有效消费相比，从未食用过营养包的儿童（比值比（OR）=1.365，P<0.001）或处于“无效消费”类型的儿童（OR=1.265，P=0.034）均与贫血呈正相关。
自贫困地区儿童营养改善项目启动以来，贫困地区儿童贫血患病率显著降低。有效消费是确保营养包贫血干预效果的关键。
