Carrying out a confusingly constructed pr release through the University of Pittsburgh, numerous news outlets have erroneously stated that the possibility of HIV for bisexual guys in america is related to the danger for heterosexual guys. A bad reports, in outlets including health regular and WebMD, essentially turn on a confusion between your quantity of HIV infections among hetero- versus homosexuals, therefore the price of illness in each group that is respective.
Presenting their findings in the United states Public wellness Association’s 141st Annual Meeting & Exposition in Boston, scientists through the University of Pittsburgh Graduate class of Public Health carried out meta-analyses of 31 systematic articles that offered information on HIV prevalence and danger among males who possess intercourse with males just (homosexual) and males who possess intercourse with men and women (bisexual).
The investigators discovered that men that are bisexual an HIV prevalence price 60 % less than compared to homosexual men. They theorized that this difference between HIV prevalence had been because bisexual males had been additionally 60 per cent not as likely than homosexual guys to report unprotected receptive anal sex.
Bisexuals, they estimated, have an HIV prevalence price of approximately 10 %: away from a believed 1.2 million men that are bisexual the usa, 121,800 are HIV good. a comparable wide range of heterosexual guys are coping with HIV.
The following is where in actuality the news reports got confused: The reports suggest that the possibility of HIV is similar both for bisexual and men that are heterosexual. But this could simply be real in the event that price of HIV had been equivalent between your two teams. What exactly is just the same involving the two teams may be the number of instances. The rate of HIV infection for straight men is therefore a small fraction of that of bisexual men’s because there are vastly more heterosexual than bisexual men in the country.
The university’s release states that the idea of viral “bridging,” by which bisexual males contract HIV from guys then transfer to ladies, happens to be “exaggerated.” (the analysis abstract puts this more equivocally, calling the idea “relatively overstated.”) but, the production doesn’t simplify whether this exaggeration is due to misunderstandings concerning the real amount of bisexuals, the amount of bisexuals coping with HIV, or perhaps the price of HIV among bisexuals since it compares with either homosexual guys or heterosexuals.

Both the WebMD and healthcare constant tales additionally inaccurately suggest that the scientists carried out an analysis of over 3,000 studies to attain their conclusions. In reality, the detectives evaluated 3,474 articles so that you can appear aided by the 31 documents they eventually utilized in their analysis. This important difference, the university press release is vague, only stating that the researchers “reviewed over 3,000 scientific articles” for the study while the study abstract clarifies.
In a message trade with POZ and AIDSmeds, Allison Hydzik, a University of Pittsburgh Schools regarding the Health Sciences representative, acknowledged the inaccuracies when you look at the news reports and included that neither health constant nor WebMD had contacted the institution for clarification.
Hydzik defended the university’s release, saying, “The pr release wasn’t intended to anyone that is mislead and also the facts it presents are an exact representation associated with research. The production ended up being designed to bring focus on this research that is important which highlights the requirement for nationwide, bisexual-specific information collection and financing for HIV prevalence research in bisexual males. Such information is essential in avoidance, evaluation and treatment outreach efforts.”
