We analyzed data from the CDC Pregnancy Risk Assessment of Monitoring System, specifically Standard Core and Phase 8 responses, with 9549 respondents across the United States through SPSS 28 software in this cross-sectional study. Two variables assessed PCOS status in respondents: history of PCOS and PCOS during pregnancy. With a history of PCOS, there were significantly increased odds of diabetic (OR 1.665, p < 0.001), hypertensive disorders (OR 1.589, p < 0.001) during pregnancy, neonatal mortality (OR 1.550, p < 0.001), cesarean section (C/S) (OR 1.489, p < 0.001), and preterm prelabor rupture of membranes (PPROM) (OR 2.081, p < 0.001). With PCOS diagnosed during pregnancy, there were significantly greater odds of diabetes (OR 3.278, p < 0.001), hypertensive disorders (OR 2.935, p < 0.001) during pregnancy, and significantly decreased risk for small for gestational age (2 standard deviations) (OR 0.337, p = 0.024). PCOS is a significant risk factor that contributes to maternal morbidity. Our results support the hypothesis that PCOS’ impact extends well into a woman’s obstetrical journey, with varying degrees of associated adverse maternal and fetal risks. Preliminary pathophysiologic explanations associated with PCOS gestational diabetes include pre-existing insulin resistance. Meanwhile, altered placentation and endovascular changes associated with PCOS secondary to a baseline deranged metabolic environment predispose patients to developing hypertensive disorders, PPROM, and preterm delivery. Associations between neonatal mortality and C/S can be attributed to elevated maternal body mass index. The pathophysiologic link between PCOS and the above obstetrical outcomes still remains unknown, necessitating further investigation;however, this study identifies the outcomes that require the most attention at this time.展开更多
