Introduction Screening for specific sexually transmitted diseases (STDs) during pregnancy has been a longstanding public health recommendation. Prior studies have described associations between these infections and socioeconomic factors such as race/ethnicity and education. Objectives We evaluated the prevalence of STDs and the correlation socioeconomic factors have with the presence of these infections among pregnant women in the United States. Methods We conducted an analysis using self-reported data from 12,948 recently pregnant women from the Pregnancy Risk Assessment Monitoring System (PRAMS) in 5 states during 2009-2011. Responses to questions about curable STDs (chlamydia, gonorrhea, syphilis, trichomoniasis) diagnosed during pregnancy were utilized to calculate weighted STD prevalence estimates and 95% confidence intervals (CI). A logistic regression was also conducted to identify maternal socioeconomic characteristics significantly associated with STDs; results are displayed as adjusted prevalence ratios (aPR). The PRAMS protocol was approved at PRAMS participating sites and by CDC's Institutional Review Board. Results Overall, 3.3% (CI 2.9-3.7) reported ≥ 1 curable STD during her most recent pregnancy. The adjusted STD prevalence was higher among women with younger age (aPR, 2.4; CI 1.8-3.4), non-Hispanic black race/ethnicity (aPR, 3.3; CI 2.4-4.1), unmarried status (aPR, 2.1; CI 1.4-3.0), no college education (aPR, 1.4; CI 1.0-1.9), annual income < $25,000 (aPR, 2.0; CI 1.3-3.2), and no pre-pregnancy health insurance (aPR, 1.4; CI 1.1-1.8). Conclusions for Practice This is the largest study of prevalence of self-reported curable STDs among U.S. pregnant women. Differences in STD prevalence highlight the association between certain socioeconomic factors and the presence of STDs.
