摘　　要：目的探究婴幼儿有效服用营养包与发热、腹泻2周患病率之间的关系。方法 2017年6—9月,通过多阶段随机抽样抽取2952名河南省10个县贫困地区6~24月龄婴幼儿,利用营养包项目组编制的问卷对婴幼儿看护人一对一进行面访式问卷调查,获得婴幼儿2周患病率相关信息。采用结构方程模型进行多因素分析。结果调整可能的影响因素后,有效服用营养包降低婴幼儿发热(β=-0.279,P=0.001)、腹泻(β=-0.182,P=0.042)2周患病率;看护人营养知识、营养包益处认知通过"营养知识-益处认知-有效服用-发热/腹泻"的链式中介间接降低婴幼儿发热(γ=-0.002, 95%CI-0.004^-0.001,P=0.003)、腹泻(γ=-0.001, 95%CI-0.003~0.000,P=0.049)2周患病率。结论婴幼儿有效服用营养包可降低发热、腹泻2周患病率;看护人营养知识及营养包益处认知通过提高婴幼儿营养包服用有效性从而间接降低发热、腹泻2周患病率。OBJECTIVE To identify the relationship between fever and diarrhea 2-week prevalence and Yingyangbao(YYB) effective consumption among infants and young children. METHODS A total of 2952 infants and young children aged from 6 to 24 month in 10 impoverished counties of Henan province were selected by multi-stage random sampling between June and September 2017. To acquire 2-week prevalence information of infants and young children, their caregivers were investigated by self-made questionnaire. The structural equation model was utilized in multi-factor analysis. RESULTS After adjusting potential confounders, YYB effective consumption reduced2-week prevalence of fever(β=-0.279, P=0.001) and diarrhea(β=-0.182, P=0.042) among infants and young children. Nutrition knowledge and YYB benefit cognition of caregivers reduced2-week prevalence of fever(γ=-0.002, 95%CI-0.004^-0.001, P=0.003) and diarrhea(γ=-0.001, 95%CI-0.003~0.000, P=0.049) indirectly through chain mediation path of "nutrition knowledge-YYB benfit cognition-YYB effective consumption-fever/diarrheal" CONCLUSION YYB effective consumption can reduce 2-week prevalence of fever and diarrhea among infants and young children. Nutrition knowledge and YYB benefit cognition can improve YYB effective consumption and thus reduce 2-week prevalence of fever and diarrhea indirectly.
