“…Serosorting is a recent concept, its definition is still being developed and no consensus has been reached in literature so far [13,15,21]. This explains why the comparison of our results with those of other studies is difficult.…”

“…Recently, sexual behaviours aiming at reducing the risk of HIV transmission have been reported: serosorting with casual partners, negotiated safety with regular partners, strategic positioning, withdrawal before ejaculation [10][11][12][13]. The first, serosorting, consists of engaging in unprotected anal sex only with partners of the same HIV serostatus as oneself.…”

We examined whether men who have sex with men (MSM) in France have adopted serosorting with their casual partners, serosorting being one strategy to reduce the risk of HIV transmission. We expected to see the same predictors of this practice with casual partners in France as in other similar MSM communities (HIV-seropositive, Internet dating). Data from a cross-sectional survey was used, based on a self-administered questionnaire conducted among readers of the gay press and users of gay websites in 2004. The study population consisted of MSM who reported their HIV status, as well as the practice of unprotected anal intercourse (UAI) with a casual partner at least once during the previous 12 months. Among 881 respondents included in the analysis, 195 (22%) had practiced serosorting: 14% among HIV-seropositive men and 26% among HIV-seronegative men. Serosorting was independently associated with the use of cruising venues (AOR 0.28, p=0.001) and Internet dating (AOR 2.16, p=0.051) among HIV-seropositive men, whereas it was independently associated with the use of cruising venues (AOR 0.59, p=0.013) and the fact of having less partners (AOR 1.50, p=0.046) among HIV-seronegative men. Serosorting requires an up-to-date knowledge of HIV serostatus for MSM and their UAI casual partners, and does not prevent from acquiring other sexually transmitted infections. Prevention campaigns are needed to underline the risks associated with serosorting.

“…For example, in Kenya, the HIV prevalence among the general population ranged from 6.70% in 2003 to 5.60% in 2012 (Kenya AIDS response progress report 2014) while that of MSM was 24.60% during the same period [21,51]. Likewise, whereas the national prevalence of HIV in Zambia was documented at 15.20% among heterosexual adults, it was 33.30% among MSM [56][57][58][59][60][61]. A similar trend was documented among Tanzanian MSM in Zanzibar, with 12.3% HIV prevalence while that of the local general population was 2.00% [9].…”

Background: In the extremely homophobic conditions in Tanzania and other countries in sub-Saharan Africa (SSA), men who have sex with men (MSM) experience disproportionate amounts of both HIV infection and psychosocial health problems, but no research has been conducted to examine the synergistic or additive effects of these adversities on their experiences. While the predominantly deficit-based research approach has identified various HIV risks and vulnerabilities, any naturally occurring protective and resilience factors that these men naturally employ to these health-related adversities remain undetermined.

“…Among HIV-negative MSM, serosorting appears to be more common and more successfully adhered to than consistent condom use (McFarland et al, 2012). Serosorting among HIV-positive men may be effective at reducing HIV transmission to previously uninfected partners and is thought to be responsible, in part, for reduction in HIV incidence in certain settings despite rises in other sexually transmitted infections (STIs) and sexual risk behavior (Truong et al, 2006). However, serosorting practices among HIV-positive men may come at a cost of both increased STIs (Golden, Dombrowski, Kerani, Stekler, 2012) and possibly HIV superinfection (Smith et al, 2004).…”

The objectives of this study were to characterize men who have sex with men (MSM) with intention to serosort and to identify factors associated with subsequent failure, defined as potentially discordant unprotected anal intercourse (PDUAI) events. Time-location sampling was used to recruit MSM into a longitudinal study of seroadaptive behaviors in San Francisco. Intention to serosort was assessed at baseline, while sexual behavior in the subsequent 6 months was assessed at follow-up. HIV-negative frequent methamphetamine users were less likely (odds ratio [OR] = 0.14; 95% CI [0.03, 0.81]) and HIV-positive frequent methamphetamine users were more likely (OR = 1.99; 95% CI [1.07, 3.69]) to intend to serosort than nonusers. Among HIV-positive and HIV-negative MSM with intent to serosort, those who frequently used alcohol, methamphetamine, or "downers" had significantly more episodes of PDUAI compared to nonusers. Challenges to serosorting, particularly substance use, should be addressed in HIV prevention and treatment programs that promote seroadaptive behaviors.
