Note: The BRAB sexual-risk score included 9 questions. To calculate the sexual-risk score, questions asked about (1) sexual orientation (score: 0 or 1, with bisexual as the reference category), (2) number of male partners, (3) number of female partners, (4) frequency of exchanging sex for drugs, (5) frequency of exchanging drugs for sex, (6) frequency of exchanging sex for money, (7) consistency of condom use, (8) frequency of exchanging money for sex, and (9) frequency of sex with someone of known HIV/AIDS positive status. Questions (2)–(9) used 4-point ratings scales, scored 0–3 (e.g., 0 = “Not at All”, 3 = “Everyday”). Because only 3 participants responded in the affirmative for (8), and no participant responded in the affirmative for (9), inferential analyses could not be performed for these items, and they are omitted from the table. The BRAB drug-risk score includes 11 questions; 10 were based on prior literature [12, 15–16] and 1 question, frequency of sharing a straw or dollar bill, was added due to anecdotal reports of methods for drug administration in the Baltimore area. To calculate the drug-risk score, questions asked about: (1) injection drug use status (score: 0 or 1, with yes the reference category), (2) needle sharing status (score: 0 or 1, with yes the reference category), (3) number of people with whom needles were shared, (4) frequency of having others use needles after you, (5) number of visits to a shooting gallery, number of times sharing (6) rinse water (7) cookers (8) cottons, or (9) straws, (10) frequency of back-loading, and (11) sharing needles with someone who had HIV/AIDS. Questions (3)-(11) used 4-point rating scales, scored 0–3 (e.g., 0 = “Not at All”, 3 = “Everyday”). Because no participant responded in the affirmative for (11), inferential analyses could not be performed for this item, and it is omitted from the table. Results in the table are the significant exponentiated Poisson regression coefficients [exp(b)] and their standard errors, with the exception of sex-risk item (1) and drug-risk items (1) and (2), for which the odds ratios [exp(b)] and their standard errors are reported because logistic regression analyses were performed for these binary items. In the case of the Ethnicity effect, exp(b) represents the mean differences between the two ethnic groups (White v. non-White, as the reference group).
