Participants who consented and completed the NHBS interview and HIV test.
Participants who had an HIV-positive NHBS test result.
Participants were unaware of their HIV infection if they reported (1) no previous HIV-positive test result or no previous HIV test, (2) had a confirmed HIV-positive NHBS test result (blood test), and (3) had no detectable antiretroviral drugs in their blood sample.
MSM analysis was limited to men who reported ever having sex with another man, were aged ≥18 y, and lived in the participating NHBS city.
Race/ethnicity is presented because it is associated with differences in HIV prevalence and access to health care. Race/ethnicity were self-reported by participants using a standard 2-question measure of race/ethnicity. Participants were asked to report their race (black/African American, American Indian/Alaska Native, Asian, Native Hawaiian/other Pacific Islander, white, or multiple race) and ethnicity (Hispanic/Latino: yes/no) separately.6 A 4-category race/ethnicity variable was coded as follows: participants reporting Hispanic/Latino ethnicity were considered Hispanic, regardless of race; all non-Hispanics were categorized as black, white, or other race. “Other race” included American Indian/Alaska Native, Asian, Native Hawaiian/other Pacific Islander, and those of multiple race.
PWID analysis was limited to men and women who injected drugs not prescribed to them in the past 12 mo, were aged ≥18 y, and lived in the participating NHBS city.
