Research on opioid use disorder (OUD) in pregnancy has mainly considered women in urban areas receiving treatment, with less known about women in rural areas. We sought to describe demographics and substance use characteristics of pregnant women with OUD and to compare the women based on urbanicity, in a state (Kentucky) with unfavorable economic conditions in many rural counties; we hypothesized that pregnant women in rural areas would have greater adversity, broadly defined, related to substance use. Using data collected from a larger project between 2017 and 2020, we analyzed characteristics of 93 pregnant women (59 rural and 34 urban) with OUD; we examined data in medical, employment, substance use, legal, family history, relationship, and psychiatric health domains, both overall and within rural (population <50,000) and urban (population ≥50,000) strata. Pregnant women with OUD from rural and urban areas were similar on almost all attributes. Among the few significant differences, 30% from urban areas perceived inadequate prenatal care versus 11% from rural areas (p = 0.024); 21% of urban women used amphetamines/methamphetamines in the month before delivery versus 0% of rural women (p < 0.001); and rural women had longer most recent abstinence from substance use than their urban counterparts (medians 7.0 and 2.8 months, p = 0.049). The few significant differences that were discovered favored rural women. These findings, contrary to our hypothesis, suggest that tailoring interventions may require more than focusing on geography. The participants in this study were pregnant women being treated for OUD, and as such there is patient contribution of data.
