title: HIV Testing and HIV Serostatus-Specific Sexual Risk Behaviour Among Men Who Have Sex with Men Living in England and Recruited Through the Internet in 2001 and 2008.
abstract: Using data from two large internet-recruited surveys in England in 2001 and 2008, we examine HIV status-specific patterns of unprotected anal intercourse (UAI). In adjusted comparisons between our 2008 and 2001 samples, there was evidence of a greater proportion of men living with diagnosed HIV, a reduction in sexual partners and in UAI with partners of unknown HIV status among men not tested HIV positive, increases in anal intercourse and UAI among men with diagnosed HIV and an increase in insertive UAI with HIV-positive men among men never tested for HIV. However, we found no evidence for increases in negotiated safety or sero-sorting. The data are compatible with a concentration of sexual risk among men with diagnosed HIV, countering an overall trend towards less risk taking among men not tested HIV positive.
