Nonuse of Contraception at Conception Due to Partner Objection and Pregnancy-Related Health Care Utilization, Postpartum Health, and Infant Birth Outcomes.

Objective: Reproductive coercion has been associated with adverse reproductive health experiences. This study examined the relationship between nonuse of contraception due to partner objection, one aspect of reproductive coercion, and selected pregnancy-related outcomes. Methods: We used 2016-2020 data from the Pregnancy Risk Assessment Monitoring System in 22 jurisdictions to assess the prevalence of nonuse of contraception due to a partner objection by select characteristics among individuals with a recent live birth who reported an unintended pregnancy. We calculated adjusted prevalence ratios (aPRs) to understand associations with health care utilization, postpartum behaviors and experiences, postpartum contraceptive use, and infant birth outcomes. Results: Among people with a recent live birth in the study jurisdictions (n = 29,071), approximately 5% reported nonuse of contraception due to a partner objection and unintended pregnancy. This experience was associated with lower prevalence of attending a health care visit before pregnancy (aPR 0.8, 95% confidence interval [CI] 0.7-0.9), first trimester prenatal care, and attending a postpartum checkup (aPR 0.7, 95% CI 0.6-0.9 for both). Higher prevalence was observed for postpartum depressive symptoms (aPR 1.3, 95% CI 1.1-1.6) and partner objecting to using birth control postpartum (aPR 2.8, 95% CI 2.1-3.9). Conclusions: Nonuse of contraception due to a partner objection at conception was associated with poor mental health and lower health care utilization around the time of pregnancy. Prevention efforts may include strategies that ensure provider screening for intimate partner violence, and evidence-based approaches that teach about healthy relationships, enhance self-efficacy, and address underlying drivers of violence.
