[Relationship between 2-week prevalence of fever and diarrhea and Yingyangbao consumption among infants and young children in impoverished area of Henan Province]

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.
