Reduction in child marriage is highly correlated with a decline in maternal and child morbidity and mortality. Nigeria has taken a step to reduce child marriage through the Child Rights Act; however, 11 states in the Northeast and Northwest are yet to implement these laws despite the documented benefits. Estimates predict that a 70% reduction of maternal deaths can be achieved by a 10% reduction in child marriage. Additionally, the $7.6 billion lost in earning and productivity of human capital from (...) child marriage annually can be averted. A reduction in child marriage can also decrease violence against girls and improve educational level attainment. We propose that the Nigerian government should enact the Maternal and Child Health Country-wide Policy to give a national security treatment to maternal and child health matters. It will ensure that policies passed at the federal level with the potential to reduce maternal and child mortality can be automatically adopted nationwide. (shrink)
