Association of maternal birth weight and maternal preterm birth with subsequent risk for adverse reproductive outcomes: The Women's Health Initiative

Individuals reporting a birthweight <6 lbs. are 20% more likely to experience stillbirth and 70% more likely to have a low birthweight infant.

• A history of being born preterm is associated with increased risks of infertility, miscarriage, preeclampsia, and gestational diabetes.
• Individuals with a birthweight ≥10 lbs. have a higher likelihood of having a high birthweight infant and are less likely to have a low birthweight infant.
• Those born preterm are also more likely to deliver a preterm or low birthweight infant.
• The findings suggest that individuals born at extreme birthweights and preterm may require closer monitoring during their pregnancies.
