Stunting and lead: using causal mediation analysis to better understand how environmental lead exposure affects cognitive outcomes in children

ConclusionsWe used a novel method of mediation analysis to test whether stunting  mediated the adverse effect of prenatal lead exposure on cognitive outcomes in Bangladesh. While we did not find that stunting acted as mediator of lead’s effect on cognitive development, we found significant effect modification by stunting. Our results suggest that children with stunting are mo re vulnerable to the adverse effects of low-level lead exposure.
