Chemsex and mental health as part of syndemic in gay and bisexual men.

A commentary is provided on the study reported by Garrett Prestage and his colleagues, which examined the relations between mental health states, non-injection drug use and sexual risk behaviors in a cross-sectional sample of 3,017Australian gay and bisexual men. We provide a summary of the findings in relation to the extant literature on the interconnectedness of these behaviors and health states and interpret the findings in this regard, noting both strengths and limitations. We couch our commentary in a theory of syndemics for considering how these associations may manifest and for informing both research and practice. While the data from this investigation posit risk they also point to strength and suggest the application of a resilience framework for addressing the health needs of gay and bisexual men.
