Community-wide awareness that ART provides protection against HIV has the
potential to increase perceived safety and thereby increase condomless anal sex
among men who have sex with men (MSM). Furthermore, reductions in condom use can
increase exposure to sexually transmitted infections, which in turn can reduce
the protective effects of ART on HIV transmission. The current study extends
previous community-based behavioral surveillance research on beliefs regarding
use of ART for HIV prevention and sexual practices among MSM. Anonymous
cross-sectional community surveys were collected from 1831 men at the same Gay
pride event in Atlanta, GA four times over nearly two decades; 1997,
2005–2006 (the 2006 survey over-sampled African Americans to diversify
the study), and 2015. Results indicate clear and consistent trends of increasing
beliefs that HIV treatments reduce HIV transmission risks, reflecting the
dissemination of HIV prevention research findings. Changes in treatment beliefs
coincide with increased rates of condomless anal intercourse. Increased beliefs
that treatments prevent HIV and increased condomless anal sex were observed for
both HIV positive men and men who had not tested HIV positive. Results
illustrate the emergence of an era where ART is the focus of HIV prevention and
community-held beliefs and behaviors regarding definitions of risk create a new
and potentially problematic environment for HIV transmission.
