Risk of recurrent preterm birth among women according to change in partner

Abstract: There is well-established literature indicating change in partner as a risk for preeclampsia, yet the research on the risk of preterm birth after a change in partners has been sparse and inconsistent. Using a population of California live born singletons, we aimed to determine the risk of preterm birth after a change in partner between the first and second pregnancies. The risk of preterm and early term delivery in the second pregnancy was calculated for mothers who did or did not change partners between births with the referent group as women who delivered both pregnancies at term and did not change partners. Adjusted odds ratios (ORs) and their 95% confidence intervals (CIs) were calculated. Relative to women who delivered at 39 weeks or later in the second pregnancy and did not change partners, preterm birth risks were somewhat lower for women who changed partners between the first and second pregnancies compared to those women who did not change partners. For example, 10.6% of women who did not change partners and delivered their second pregnancy before 34 weeks also delivered their first pregnancy before 34 weeks, while 8.5% of women who changed partners delivered before 34 weeks. Findings suggest partner change may alter the risk of preterm birth.
