Does Having an Alcohol Use Disorder Impact Sexual Behavior or Sexually Transmitted Infection (STI) Prevalence among Men Who Have Sex with Men (MSM) and Transgender Women (TW) in Lima, Peru?
High-risk MSM and TW recruited from STI clinics completed a survey on CAI and number of sex partners in the past 3 months, and alcohol use. An AUDIT score ≥8 determined AUD presence. Recent STI diagnosis included rectal gonorrhea/chlamydia (NAAT), syphilis (RPR titer≥1:16), and/or new HIV infection within 6 months. Prevalence ratios (PR) were calculated using Poisson regression.
Among 312 MSM and 89 TW, the median age was 30 years (IQR 18-58) and 45% of participants (181/401) had an AUD. Among those with an AUD, 164 (91%) were hazardous or harmful drinkers, and 17 (9%) had alcohol dependence. Higher CAI was reported by participants with an AUD vs. without (84% vs. 73%, p=0.007). There was no difference in recent STI/HIV among participants by AUD status (32%, p=0.961). CAI was associated with having an AUD (aPR=1.13), self-report of bi-or heterosexual (aPR=1.13), and having ≥6 sex partners (aPR=1.22) in multivariable regression (all p-values<0.05). Recent STI/HIV infection was associated with being receptive (aPR=1.81) or both receptive and insertive (aPR=2.35) during anal sex (p-values<0.05).
Although AUDs were associated with CAI, there was no association of AUD with recent STI/HIV in our sample. This may suggest that STI prevalence within this key population confers greater risk than individual risk behaviors, necessitating population-level interventions.
