Hypothesis
What is the potential population impact and cost saving from modifying key HIV risk factors among men who have sex with men in Sydney, Australia?
Conclusion
The study found that eliminating unprotected anal intercourse with HIV-positive partners could significantly reduce HIV infections among men who have sex with men.
Supporting Evidence
- Unprotected anal intercourse with an HIV-positive partner was reported by 5% of men.
- The hazard ratio for this behaviour was 16.1.
- The average lifetime healthcare costs attributable to this behaviour were estimated at $AUD102 million.
- UAI with unknown HIV status partners was reported by 25% of men, with a hazard ratio of 4.4.
Takeaway
If men stop having unprotected sex with partners who are HIV-positive, many fewer people will get HIV.
Methodology
Proportional hazard analyses were used to examine the association between sexual behaviours and HIV incidence in a cohort of HIV-negative men who have sex with men.
Potential Biases
Self-reported data may be subject to recall and measurement bias.
Limitations
The study's findings may not be generalizable due to non-random recruitment and reliance on self-reported data.
Participant Demographics
HIV-negative men who have sex with men, primarily recruited from community-based sources.
