LBO-1.5 Men who have sex with men (MSM) have a 140-fold risk for HIV and syphilis compared with other men in New York City
2011
Background While men who have sex with men (MSM) comprise the majority of new HIV and new syphilis cases in the U.S., understanding the full burden of disease among them has been challenging as direct estimates of Men who Have Sex with Men (MSM) numbers in the general population have been largely unavailable. We describe the population of Men who Have Sex with Men (MSM) in New York City, compare their demographics, risk behaviours, and new HIV and primary and secondary (P&S) syphilis rates with those of men who have sex with women (MSW), and examine trends in disease rates among Men who Have Sex with Men (MSM). Methods Population denominators and demographic and behavioural data were obtained from population-based behavioural surveys during 2005–2008. Numbers of new HIV and P&S syphilis diagnoses were extracted from citywide disease surveillance registries. We calculated overall, age- and race/ethnicity-specific case rates and rate ratios for Men who Have Sex with Men (MSM) and MSW, and analysed trends in Men who Have Sex with Men (MSM) rates by age and race/ethnicity. Results The average prevalence of same-sex behaviour among sexually active men during 2005–2008 (5.0%; 95% CI 4.5 to 5.6) differed by age (peaking at 8% among 40–49-year-old men) and race/ethnicity (2.3% among non-Hispanic black men; 7.4% among non-Hispanic white men). Compared to MSW, Men who Have Sex with Men (MSM) differed significantly on all demographics and reported a higher prevalence of condom use at last sex and of HIV testing, but also more sex partners; 38.4% of Men who Have Sex with Men (MSM) and 13.6% of MSW reported =3 partners in the last year (p Conclusions The substantial population of Men who Have Sex with Men (MSM) in NYC is at high risk for transmission of sexually transmitted infections given high disease rates and ongoing risk behaviours. There is significant overlap between HIV and P&S syphilis epidemics in NYC with the relatively small subgroups of young and non-Hispanic black Men who Have Sex with Men (MSM) disproportionately affected. Integration of HIV and STD case data would allow for better identification and characterisation of the population affected by these synergistic epidemics. Intensified and innovative efforts to implement and evaluate prevention programs are required.
