ABSTRACT

To estimate the risk of repeat low birthweight deliveries among women whose first child was very low birthweight (less than 1500 g), a retrospective cohort of women who had their first and second children in Washington state between 1984 and 1991 was studied. After adjustment for potential confounding factors, a woman whose first infant was very low birthweight experienced an 11.5-fold increased risk of delivering a low birthweight (less than 2500 g) second infant (relative risk 11.5, 95% confidence interval 5.4 to 24.4). Women with a very low birthweight first infant also had a significantly increased risk of repeat very low birthweight infant (p <0.0001). Women with a previous very low birthweight delivery are at increased risk of repeat low and very low birthweight infants. This high-risk group may benefit from education regarding recurrence risk and modification of factors associated with low birthweight, as well as good prenatal care.
