Ischemic Placental Disease, Preterm Delivery, and Their Association With Opioid Use During Pregnancy.

ABSTRACT: Opioids affect placental development and function in animal models, but human data on their association with ischemic placental disease are limited. Using a cohort of pregnant women in the US nationwide Medicaid Analytic eXtract (2000-2014), we compared women with ≥2 opioid dispensings in pregnancy with unexposed women. Given an uncertain etiologically relevant window, we assessed exposure occurring in early pregnancy, late and not early pregnancy, and both early and late pregnancy. For placental abruption, preterm delivery, small for gestational age (SGA), and preeclampsia, we estimated adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) using Cox proportional hazard models adjusting for demographic factors, indications/comorbidities, and medications.
