Pre-exposure prophylaxis (PrEP) use alongside condoms is preferred by men who have sex with men and transgender women in Mexico. This suggests PrEP may not decrease condom use in HIV prevention strategies.
Area of Science:
- Public Health
- Epidemiology
- HIV Prevention
Background:
- Scaling up pre-exposure prophylaxis (PrEP) may impact existing HIV prevention methods like condom use.
- Understanding prevention preferences is crucial for effective HIV/AIDS control among key populations.
Purpose of the Study:
- To evaluate HIV prevention method preferences among men who have sex with men (MSM) and transgender women (TW) in Tijuana, Mexico.
- To assess the potential for decreased condom use with increased PrEP uptake.
Main Methods:
- Cross-sectional study involving 397 HIV-negative MSM and TW in Tijuana, Mexico.
- Analysis of 1302 sexual partnerships to determine preferences for: neither PrEP nor condoms, condoms only, PrEP only, or PrEP with condoms.
- Statistical analysis using adjusted odds ratios (AOR) and 95% confidence intervals (CI) to compare preferences.
Main Results:
- PrEP with condoms was the most preferred method (56%), followed by condoms only (24%), PrEP only (17%), and neither (3%).
- PrEP only was significantly preferred over condoms only in primary partnerships (AOR=4.13) and condomless sex partnerships (AOR=6.97).
Conclusions:
- PrEP use, particularly in combination with condoms, is highly favored among MSM and TW in Tijuana.
- Findings suggest that PrEP scale-up may not lead to a reduction in condom use in this population and similar settings.
