Key clinical point: Uterine fibroids did not increase the risk for preterm births and were not associated with any clinical preterm birth subtype.
Major finding: Prevalence of fibroids was similar in pregnancies ending in preterm and term births (10.2% and 10.3%, respectively). Presence of fibroids was not associated with an overall risk for preterm birth (adjusted risk ratio [aRR], 0.88; 95% confidence interval [CI], 0.62-1.24) or preterm birth subtypes like medically indicated (aRR, 0.92; 95% CI, 0.43-1.96) or spontaneous (aRR, 1.27; 95% CI, 0.76-2.11) preterm births.
Study details: Findings are from a prospective cohort including 4,622 women with singleton pregnancies resulting in a live birth after 20 weeks of gestation.
Disclosures: This study was funded by National Institutes of Health, American Water Works Association Research Foundation, and the National Institute of General Medical Studies. The authors declared no conflict of interests.
