Contraceptive use among cisgender women with bacterial sexually transmitted infections: A cross-sectional study

Background Data on contraceptive use among women with bacterial sexually transmitted infections (STIs) are sparse, despite this population’s high risk for unplanned pregnancy. Methods This cross-sectional study included 1623 cisgender women recently diagnosed with a bacterial STI who completed a public health Partner Services interview between January 2017 and December 2019 in King County, WA, USA. Contraceptive methods were categorized as: (1) highly or moderately effective and (2) least effective or no method. Poisson regression models were used to assess associations between individual characteristics and contraceptive method. Results Almost two thirds of the women (62.6%) reported using highly or moderately effective contraception, with 30.3% of women using long-acting contraception (LARC). More than one in three women (37.4%) reported using least effective methods or no method. Black women were less likely to report using a highly or moderately effective method compared to White women (aRR 0.58, 95% CI 0.43–0.80) and women with private insurance were more likely to report using a highly or moderately effective method compared to those with public insurance (aRR 1.67, 95% CI 1.28–2.19). Conclusions Given that many women with bacterial STIs are not desiring pregnancy, this study highlights the need for additional reproductive health services for women with recent STI diagnoses.
