Conclusion
Additional research is needed to better understand the correlation between household income and child health. It would seem important to explore several mechanisms that could explain the correlation (or the causal impact) of parentalincome on child health. Previous research has already exploredwhether nutrition and housing conditions are mechanisms through which income has an impact on child health [7,9].However, these mechanisms need re-assessing with moredetailed data on diet and living conditions. Knowledge aboutthe roles of nutrition and housing conditions will certainlyimprove the implementation of policies promoting child health.This objective is all the more important as poor health inchildhood is not only related to lower child well-being in theshort run, but also to future educational and labor marketoutcomes in the long run [32].
