Note. HBCU = historically Black colleges and universities; OR = odds ratio; CI = confidence interval. For total sample, N = 1837. The risky sexual behaviors assessed were inconsistent condom use, history of a sexually transmitted disease, and multiple sexual partners in the preceding 3 months. ORs were derived from generalized estimating equation models.
