Abstract:
HIV infections in Peru are concentrated among men who have sex with men (MSM) and transgender women (TW). HIV testing rates among them remain low, delaying entrance into care. We assessed the prevalence of frequent HIV testing (at least every 6 months) and associated factors among 310 MSM and TW who attend sexual health clinics in Lima, Peru, and who reported that they were HIV seronegative or unaware of their status. Only 39% of participants tested frequently, and 22% had never tested; 29% reported that they were at low or no risk for acquiring HIV. Reporting low or no risk for acquiring HIV was associated with frequent testing (adjusted prevalence ratio [aPR] = 1.53, 95% CI 1.13-2.08); those reporting unprotected anal sex were less likely to test frequently (aPR = 0.66, 95% CI 0.50-0.87). HIV prevalence was 12% and did not vary by risk perception categories. This at-risk population tests infrequently and may not understand the risk of having unprotected sex.
Insights
Frequent HIV testing remains low among men who have sex with men (MSM) and transgender women (TW) in Peru, despite high HIV prevalence. Many underestimate their risk, highlighting a critical gap in prevention and care engagement.
Area of Science:
- Public Health
- Epidemiology
- Infectious Diseases
Background:
- HIV infections in Peru disproportionately affect men who have sex with men (MSM) and transgender women (TW).
- Low HIV testing rates among these key populations delay crucial entry into care and treatment.
- Understanding testing behaviors is vital for targeted HIV prevention strategies.
Purpose of the Study:
- To assess the prevalence of frequent HIV testing (≥ every 6 months) among HIV-seronegative or status-unknown MSM and TW in Lima, Peru.
- To identify factors associated with frequent HIV testing in this population.
- To examine the relationship between risk perception and HIV testing frequency.
Main Methods:
- Cross-sectional study involving 310 MSM and TW attending sexual health clinics in Lima, Peru.
- Data collected on HIV testing history, sexual behaviors, and perceived risk for HIV acquisition.
- Statistical analysis using adjusted prevalence ratios (aPR) to identify associated factors.
Main Results:
- Only 39% of participants reported frequent HIV testing; 22% had never been tested.
- Reporting low or no risk for HIV acquisition was associated with more frequent testing (aPR=1.53).
- Engaging in unprotected anal sex was associated with less frequent testing (aPR=0.66). HIV prevalence was 12% and did not differ by risk perception.
Conclusions:
- A significant proportion of at-risk MSM and TW in Lima test infrequently for HIV.
- Misperceptions of risk and engagement in unprotected sex are barriers to frequent testing.
- Interventions are needed to improve HIV testing uptake and risk awareness among these populations.
