The relationship of interpregnancy interval to infant birthweight and length of gestation among low-risk women, Georgia

To examine the association between interpregnancy interval and low birthweight (< 2500 g), preterm delivery (< 37 weeks’ gestation), and inadequate fetal growth, we studied a population‐based sample of 23 388 white and 4885 black women at low risk for adverse pregnancy outcomes who delivered t...

Description
Summary:To examine the association between interpregnancy interval and low birthweight (< 2500 g), preterm delivery (< 37 weeks’ gestation), and inadequate fetal growth, we studied a population‐based sample of 23 388 white and 4885 black women at low risk for adverse pregnancy outcomes who delivered their first and second infants in Georgia from 1980 to 1992. We used fetal death and livebirth certificates. The interpregnancy interval was the time from delivery to the woman’s next conception. For each pregnancy outcome, we stratified by race and used logistic regression to assess the association between interpregnancy interval and outcome, while controlling for confounders. Intervals
