Recent Intimate Partner Violence and Oral Contraceptive Pill Adherence in a Cohort of Reproductive-Aged Women

Objective: Intimate partner violence (IPV) is an important public health problem that impacts reproductive decision-making. Although previous literature has reported a negative impact on contraceptive adherence overall, this study specifically aims to investigate the association between IPV and oral contraceptive pill (OCP) adherence.Study Design: We analyzed baseline survey data from 373 OCP users participating in the MyNewOptions study. Recent IPV was defined as any positive response to HARK, a 4-question tool assessing emotional, sexual, and physical abuse in the past year, or self-report of sexual coercion in the past 6 months. High OCP adherence was defined by self-report of missing <= 1 pill per month, which was then corroborated by pharmacy claims data. Multivariable regression analyses were performed to assess the influence of recent IPV history and patient-level variables on OCP adherence.Results: Just over half of our participants were highly adherent to OCPs (53.6%), and approximately one-quarter reported recent IPV exposure (25.2%). Women with recent IPV were significantly less likely to be OCP adherent than those without IPV (adjusted odds ratio (AOR) 0.54, 95% confidence interval (CI): 0.32-0.92). Protestant religion was also associated with high OCP adherence (AOR 2.41, 95% CI: 1.24-4.65, compared with no religious affiliation), while younger age groups (18-25 and 26-33 years) were less likely to have high OCP adherence compared with the 34-40 age group (AOR 0.45, 95% CI: 0.20-1.00 and AOR 0.40, 95% CI: 0.18-0.91, respectively).Conclusion: Recent IPV exposure is associated with low OCP adherence among women of reproductive age. ClinicalTrials.gov identifier: NCT02100124.

Automated summary

This study investigates the association between intimate partner violence (IPV) and adherence to oral contraceptive pills (OCPs). The results show that women who have recently experienced IPV are less likely to adhere to OCPs. Religious affiliation and age are also associated with high OCP adherence.
