 This study found that both young and older maternal ages were associated with poorer birth and child health outcomes in low-income and middle-income countries. Younger mothers were more likely to give birth to babies with low birth weights and shorter gestational periods, while older mothers were more likely to have children who were stunted and not able to complete their education. Additionally, both groups of mothers were more likely to have children with elevated blood sugar levels as adults. This article was authored by Professor Caroline H.D.
