Prevalence of rape-related pregnancy as an indication for abortion at two urban family planning clinics.

Objective: We sought to estimate the prevalence of rape-related pregnancy as an indication for abortion at two public Chicago facilities and to describe demographic and clinical correlates of women who terminated rape-related pregnancies.

Methods: We performed a cross-sectional study of women obtaining abortion at the Center for Reproductive Health (CRH) at University of Illinois Health Sciences Center and Reproductive Health Services (RHS) at John H. Stroger, Jr. Hospital between August 2009 and August 2013. Gestational age limits at CRH and RHS were 23+6 and 13+6weeks, respectively. We estimated the prevalence of rape-related pregnancy based on billing code (CRH) or data from an administrative database (RHS), and examined relationships between rape-related pregnancy and demographic and clinical variables.

Results: Included were 19,465 visits for abortion. The majority of patients were Black (85.6%). Prevalence of abortion for rape-related pregnancy was 1.9%, and was higher at CRH (6.9%) than RHS (1.5%). Later gestational age was associated with abortion for rape-related pregnancy (median 12days, p<.001). Younger age and Black race were associated with abortion for rape-related pregnancy at CRH only (p<.001 for both). Chlamydia and gonorrhea infection were no more prevalent among women terminating rape-related pregnancy than among those terminating for other indications.

Conclusion: Rape-related pregnancy as an indication for abortion had a low, but clinically significant prevalence at two urban Chicago family planning centers. Later gestational age was associated with abortion for rape-related pregnancy.

Implications: Rape-related pregnancy may occur with higher prevalence among some subgroups of women seeking abortion than others. Efforts to address rape-related pregnancy in the abortion care setting are needed.
