Maternal and Fetal Outcomes Among Pregnant Women With Endometriosis [ID 2683578]

INTRODUCTION: Endometriosis, a prevalent disorder affecting around 10% of reproductive-aged women, has been linked to obstetric complications during pregnancy. This study aims to evaluate endometriosis prevalence in pregnancy and its effect on maternal and newborn outcomes. METHODS: A retrospective cohort study was conducted using data from the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS) database from the United States between 1999 and 2019. Multivariate logistic regression analysis, controlling for diverse baseline maternal characteristics, was used to investigate pregnancy and newborn outcomes in births to women diagnosed with endometriosis as compared to those without. RESULTS: The cohort consisted of 16,911,497 births to women without endometriosis and 14,956 pregnant women diagnosed with endometriosis. Over the 20-year period, there was a significant upward trend in prevalence of endometriosis among births, rising from 34.9 to 160.6/100,000 births. Births to women with endometriosis exhibited distinctive demographic characteristics: being of advanced maternal age, predominantly of Caucasian ethnicity, belonging to higher income quartiles, obese, smokers, and having private insurance coverage. Births to women with endometriosis were at heightened risk of experiencing obstetric complications, including gestational diabetes, preeclampsia, preterm birth, and postpartum hemorrhage. Neonates born to mothers with endometriosis also demonstrated an elevated likelihood of growth restriction and congenital anomalies. CONCLUSION: The study highlights the evolving prevalence of endometriosis among pregnant women and establishes a strong connection between endometriosis and adverse maternal and newborn outcomes. These findings emphasize the importance of vigilant monitoring to enhance obstetrical and fetal outcomes in pregnant women with endometriosis.
