Black women who are positive for human immunodeficiency virus (HIV) are more likely than other HIV-positive women to experience poor health outcomes. Given these disparities, we compared receipt of HIV testing and other preventive services among Black, White, and Hispanic women participating in HIV prevention programs funded by the Centers for Disease Control and Prevention in2015. Data came from 61 health department jurisdictions and 123 community-based organizations. Using Wald χ2 tests, we assessed racial/ethnic differences in HIV testing by demographic characteristics, risk factors, HIV status, HIV service delivery, and (using unlinked data) participation in evidence-based HIV prevention interventions among women. We also assessed temporal changes in Black women's receipt of preventive services (2012-2015). In 2015, there were 1,326,589 HIV testing events (single sessions in which one or more HIV tests are performed to determine HIV status) that occurred among Black, White, and Hispanic women, resulting in 4,868 positive diagnoses. Proportionally fewer Black (vs. White and Hispanic) women were linked to HIV medical care within 90days (64.4% vs. 69.1% and 73.7%), interviewed for partner services (50.4% vs. 54.4% and 63.5%), and referred to risk reduction services (55.5% vs. 57.7% and 59.8%). From 2012 to 2015, HIV testing events among Black women decreased by 15.2%, but linkage to care within 90days increased by 30.6% and participation in one or more evidence-based intervention increased by 46.8% among HIV-positive Black women. Black HIV-positive women were less likely than White and Hispanic women to receive services that prevent HIV-related morbidity and mortality. Additional programmatic efforts are needed to increase the proportion of HIV-positive Black women who are linked to services to reduce HIV disparities among women.
