Pitt Public Health Analysis Challenges Assumptions About Bisexual Men and HIV Transmission

The number of HIV positive men who have sex with both men and women is likely no higher than the number of HIV positive heterosexual men, according to a U.S.-based analysis by University of Pittsburgh Graduate School of Public Health researchers. The finding challenges a popular assumption that bisexual men are responsible for significant HIV transmission to their female partners.  

Considerable Gender, Racial and Sexuality Differences Exist in Attitudes Toward Bisexuality

Men who identify themselves as heterosexual are three times more likely to categorize bisexuality as "not a legitimate sexual orientation," an attitude that can encourage negative health outcomes in people who identify as bisexual, according to an analysis led by University of Pittsburgh Graduate School of Public Health researcher Mackey Friedman, Ph.D., M.P.H.

Pitt Researchers Plan CFAR Application for 2013

On December 18, 2012, twelve HIV-AIDS researchers from the University of Pittsburgh established a Pitt CFAR Planning Working Group (PCPWG) to prepare an application to the NIH for a CFAR. Such designation would allow the University to build on its 30 year history of HIV-AIDS research. It was agreed we will proceed with the development of a regular CFAR proposal for submission June, 2013.
