Abstract

Abstract : Background: Racial/ethnic and sexual minorities face elevated risk of policing and detainment. Dual minority status is linked to disproportionate incarceration; among black men who have sex with men (BMSM) in the HIV Prevention Trials Network (HPTN) study, 60% had been incarcerated. Incarceration disrupts networks and increases partnership exchange and STI. We lack understanding of the impact of incarceration on STI risk among BMSM. Methods: We used data from HPTN 061 (N=1553) conducted in Atlanta, Boston, New York, Los Angeles, San Francisco, and Washington DC to measure longitudinal associations between incarceration within six months and twelve-month risk of multiple partnerships and biologically-confirmed STI (gonorrhea, chlamydia, syphilis). Using inverse probability of treatment weighted (IPTW) regression to account for pre-incarceration poverty, psychopathology, drug use, and STI risk, we estimated risk ratios (RRs) and 95% confidence intervals (CIs) for associations between incarceration and outcomes and assessed differences by city. Results: Approximately 14% had been incarcerated in the past six months. Controlling for site, incarceration predicted multiple partnerships (RR: 1.20, 95% CI: 1.06–1.36) and incident STI (RR: 1.08, 95% CI: 1.00–1.16). Associations with multiple partnerships and STI differed by city (joint test of interaction, p value <0.05). Incarceration was most strongly associated with multiple partnerships (RR: 1.69, 95% CI: 1.38–2.04) and STI (RR: 1.31, 95% CI: 1.04–1.64) in Washington DC. In other cities, STI RRs ranged from 0.95 to 1.08 and were not significant at the 0.05 level. Incarceration was associated with multiple partnerships in New York (RR: 1.25, 95% CI: 1.01–1.55) and Boston (RR: 1.31, 95% CI: 1.08–1.58), while RRs ranged from 0.87 to 1.08 and were not significant in other cities. Conclusion: Recent incarceration impacts STI risk among BMSM in Washington DC and the northeastern United States. Disclosure: No significant relationships.
