Pregnancy risks double in prem mums

Canadian researchers analysed the medical records of about 7400 women born preterm alongside a matched cohort of more than 16,700 women born at term between 1976 and 1995.

Of the women born preterm, 554 were born before 32 weeks. Their odds of pregnancy complications including pre-eclampsia, gestational hypertension or gestational diabetes, were nearly doubled compared to women born at term.

Pregnancy complications for women born at 32–36 weeks were elevated by 14%. The findings were independent of low weight for gestational age, the researchers said.
