“…Understanding age mixing patterns in transmission can help to determine which groups are at a greater risk and potentially guide public health interventions [23]. Our findings 270 confirm that young MSM infect one another more than expected by random mixing which supports the idea that prevention benefit could be enhanced by focusing on this small group [24].…”

Background: Near 60% of new HIV infections in the United Kingdom are estimated to occur in men who have sex with men (MSM). Patterns of mixing between different risk groups of MSM have been suggested to spread the HIV epidemics through age-disassortative partnerships and to contribute to ethnic disparities in infection rates. Understanding these mixing patterns in transmission can help to determine which groups are at a greater risk and guide prevention.Methods: We analyzed combined epidemiologic data and viral sequences from MSM diagnosed with HIV as of mid-2015 at the national level. We applied a phylodynamic source attribution model to infer patterns of transmission between groups of patients by age, ethnicity and region.Results: From pair probabilities of transmission between 19 847 MSM patients, we found that potential transmitters of HIV subtype B were on average 5 months older than recipients. We also found a moderate overall assortativity of transmission by ethnic group and a stronger assortativity by region.Conclusions: Our findings suggest that there is only a modest net flow of transmissions from older to young MSM in subtype B epidemics and that young MSM, both for Black or White groups, are more likely to be infected by one another than expected in a sexual network with random mixing.

“…A number of factors have been posited to explain the increasing incidence of HIV among YMSM, including decreasing age of sexual debut and participation in age-discordant sexual debut (i.e., having sex with an older partner). Both of these characteristics have been associated with an increased risk of engaging in condomless anal intercourse (C 0 AI) and contracting sexually transmitted infections (STIs), including HIV (3,4). …”

Sexual Debut and HIV-Related Sexual Risk-Taking by Birth Cohort Among Men Who Have Sex with Men in the United States

et al. 2016

Age-discordant and earlier sexual debut are risk factors for HIV among men who have sex with men (MSM). Despite differences in the sociopolitical landscape over time, there are no studies sampling participants from the United States that have examined the role of birth cohort in relations between sexual debut characteristics and sexual risk among MSM. We assessed sexual debut patterns and associations with sexual risk-taking in 812 adult MSM stratified by ten-year birth cohorts (i.e., before 1970, 1970–1979, 1980–1989, after 1990). Sexual debut characteristics differed by birth cohort. In multivariate models controlling for birth cohort, both younger age of sexual debut and younger age of anal sex debut were associated with an increased likelihood of condomless sex. Men born in the 1990s had increased odds of engaging in sexual risk regardless of sexual debut characteristics. Sexual risk reduction interventions tailored to the unique needs of young MSM are encouraged.

“…In essence, although there were characteristic differences in who was recruited via different venues, the wide range in places these men subsequently used to meet sex partners highlights strong potential for overlap in sexual networks. In developing strategies through which to understand HIV transmission across populations, researchers have investigated the roles that racial intermixing/homogeneity (Bohl, McFarland, & Raymond, 2011; Newcomb & Mustanski, 2013) as well as intergenerational sexual partnerships (Anema et al, 2013; Raymond & McFarland, 2009; Sowell & Phillips, 2010). These findings highlight that an additional variable, venue-frequenting patterns (Grov & Crow, 2012; Jenness et al, 2011), may also contribute to our understanding of how HIV, STIs, and other communicable pathogens (e.g., meningitis) are transmitted across seemingly separate sub-communities of MSM.…”

With limited exceptions, few studies have systematically reported on psychosocial and demographic characteristic differences in samples of men who have sex with men (MSM) based on where they were recruited. This study compared three sexually active cohorts of MSM recruited via Craigslist.org (recruited via modified time-space sampling), gay bars and clubs (recruited via time-space sampling), and private sex parties (identified via passive recruitment and listserves), finding mixed results with regard to differences in demographic characteristics, STI history, and psychosocial measures. Men recruited from sex parties were significantly older, reported more symptoms of sexual compulsivity, more likely to be HIV-positive, more likely to report a history of STIs, and more likely to self-identify as a barebacker, than men recruited from the other two venues. In contrast, men from Craigslist.org reported the lowest levels of attachment to the gay and bisexual community and were the least likely to self-identify as gay. Men from bars and clubs were significantly younger, and were more likely to report use of hallucinogens and crack or cocaine. Our findings highlight that the venues in which MSM are recruited have meaningful consequences in terms of the “types” of individuals who are reached.
