To identify the relationship between fever and diarrhea 2-week prevalence and Yingyangbao(YYB) effective consumption among infants and young children.
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.
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".
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.
探讨婴幼儿发热及腹泻两周患病率与营养包有效服用之间的关系。
2017年6月至9月，采用多阶段随机抽样方法，选取河南省10个贫困县的2952名6至24月龄婴幼儿。通过自制问卷对其照料者进行调查，以获取婴幼儿两周患病率信息。采用结构方程模型进行多因素分析。
在调整潜在混杂因素后，营养包有效服用降低了婴幼儿发热（β=-0.279，P=0.001）及腹泻（β=-0.182，P=0.042）的两周患病率。照料者的营养知识及对营养包益处的认知，通过“营养知识-营养包益处认知-营养包有效服用-发热/腹泻”的链式中介路径，间接降低了发热（γ=-0.002，95%CI -0.004～-0.001，P=0.003）及腹泻（γ=-0.001，95%CI -0.003～0.000，P=0.049）的两周患病率。
营养包有效服用可降低婴幼儿发热及腹泻的两周患病率。营养知识及对营养包益处的认知可提高营养包有效服用率，从而间接降低婴幼儿发热及腹泻的两周患病率。
