BACKGROUNDnDrug use among gay and bisexual men (GBM) is higher than most populations. The use of crystal methamphetamine, erectile dysfunction medication (EDM), and amyl nitrite have been associated with sexual risk behaviour and HIV infection among gay and bisexual men (GBM).nnnOBJECTIVEnThis paper describes an online prospective observational study of licit and illicit drug use among GBM and explores baseline prevalence of drug use in this sample. Capturing these data poses challenges as participants are required to disclose potentially illegal behaviours in a geographically dispersed country. To address this issue, an entirely online and study specific methodology was chosen.nnnMETHODSnMen living in Australia, aged 16.5 years of age or older, who identified as homosexual or bisexual or had sex with at least one man in the preceding 12 months were eligible to enrol.nnnRESULTSnBetween September 2014 and July 2015, a total of 2250 participants completed the baseline questionnaire, of whom, 1710 (76.0%) consented to six-monthly follow-up. The majority (65.7%) were recruited through Facebook targeted advertising. At baseline, over half (50.5%) the men reported the use of any illicit drug in the previous six months, and 28.0% had used party drugs. In the six months prior to enrolment, 12.0% had used crystal methamphetamine, 21.8% had used EDM, and 32.1% had used amyl nitrite. Among the 1710 men enrolled into the cohort, 790 men had used none of these drugs.nnnCONCLUSIONnEase of entry and minimal research burden on participants helped ensure successful recruitment into this online cohort study. Study outcomes will include the initiation and cessation of drug use, associated risk behaviours, and health consequences, over time. Results will provide insights into the role gay community plays in patterns of drug use among GBM.

Estimates of the proportion of HIV infections coming from within regular sexual relationships among gay and bisexual men (GBM) vary widely. Research surveys use various partner type categories, but there is little understanding of how men classify their partners. We conducted an online cross-sectional survey of Australian GBM exploring sexual relationships, including 2057 men reporting on 2566 regular partnerships. Just over half of the partnerships were considered ‘relationships’, while the remainder were non-romantic ‘fuckbuddy’-style arrangements. In multivariable analysis, factors associated with considering the partnership a ‘relationship’ were: using a ‘romantic’ descriptor, partnership length, monogamous agreements, any condomless anal sex with each other, love, and commitment. The category of ‘regular partner’ can mask diverse partnership types, which have different meanings to GBM, associated behaviours, and HIV risks. Certain HIV prevention techniques may be more suited to particular types of partnerships. ‘Fuckbuddy’ arrangements need to be more explicitly acknowledged in HIV prevention.

Online Dating Among Australian Gay and Bisexual Men: Romance or Hooking Up?

Garrett Prestage; Benjamin R. Bavinton; Jeffrey Grierson; Ian Down; Phillip Keen; Jack Bradley; Duane Duncan

Increasingly, gay and bisexual men (GBM) meet casual sex partners online and this has been associated with sexual risk behavior. How do GBM meet regular partners? This online anonymous survey of 4215xa0GBM included 2562 men with a primary regular partner (PRP) who were included in these analyses. Mean age of the sample was 38.1xa0years. 60.3xa0% had met their PRP at least 2xa0years earlier. Meeting their PRP online increased from 14.0xa0% before 2001 to 79.9xa0% in 2013–2014. At all time points, men who met their PRP online were somewhat older than those who met their PRP offline. Regardless of how they met their PRP, most men met casual sex partners online. Among GBM, meeting sexual and romantic partners online has replaced other methods, for all age groups. The population of GBM who use the internet for this purpose is now equivalent to all sexually active GBM.

Negotiating gay men’s relationships: how are monogamy and non-monogamy experienced and practised over time?

Steven Philpot; Duane Duncan; Jeanne Ellard; Benjamin R. Bavinton; Jeffrey Grierson; Garrett Prestage

Abstract When viewed over time, many gay men’s relationships are not static, or firmly fixed to monogamy or non-monogamy. This paper uses in-depth interviews with 61 Australian gay men to explore how monogamy and non-monogamy are experienced over time, expectations of what constitutes the norms regarding gay men’s relationships and how couples experience and practices change. Although some gay men may idealise monogamy, particularly at the beginning of a relationship, it is often experienced as temporary. Non-monogamy is often seen as a likely prospect for gay relationships owing to the social and cultural norms that operate in gay communities. These expected trajectories are reflected in practice – many relationships begin monogamously and then become non-monogamous over time. While the application of ‘rules’, experimentation and flexibility can facilitate change, couples may struggle to navigate new territory as their relationship structures shift. This is particularly the case when partners value monogamy and non-monogamy differently, or when one partner’s values change. These findings shed light on how gay men approach change to the status of ‘fidelity’ within their relationships, and the tensions and opportunities that change can produce for couples.

‘I’d much rather have sexual intimacy as opposed to sex’: Young Australian gay men, sex, relationships and monogamy:

Duane Duncan; Garrett Prestage; Jeffrey Grierson

Few studies have explored how young gay men negotiate opportunities for rethinking sexual and relationship life associated with gay sexual cultures upon coming out. Drawing on qualitative interview data with Australian gay men aged 18–30, this article explores a tension these participants described between a desire for monogamy as the basis to a committed, enduring and mature relationship on one hand, and sexual opportunities associated with ‘the gay scene’ on the other. We analyse these mens negotiation of this tension in the context of wider political shifts in the social status of gay mens relationships, encapsulated in a debate between those who see ‘homonormativity’ and those who see transformation in the contemporary relationship practices of gay men.

Off-Label Use of Phosphodiesterase Type 5 Inhibitor Erectile Dysfunction Medication to Enhance Sex Among Gay and Bisexual Men in Australia: Results From the FLUX Study

Mohamed Hammoud; Fengyi Jin; Toby Lea; Lisa Maher; Jeffrey Grierson; Garrett Prestage

BACKGROUNDnGay and bisexual men (GBM) use oral erectile dysfunction medications (EDMs) often with little evidence of medical indication necessitating their use.nnnAIMnTo investigate the prevalence, contexts, and motivations for oral EDM use and its relation to sexual risk behavior.nnnMETHODSnA total of 2,250 Australian GBM completed an online survey of licit and illicit drug use and their associated behaviors. Multivariate logistic regression analysis identified factors associated with use of EDMs in the previous 6 months and, for those who had used EDMs, factors associated with use on a weekly basis.nnnOUTCOMESnAny EDM use and at least weekly use in the previous 6 months.nnnRESULTSnThe median age of the sample was 33.0 years (rangexa0= 16-81). Two thirds (67.7%) reported no lifetime history of EDM use. Approximately 1 in 10 participants (11.1%) had last used an EDM more than 6 months previously. In the previous 6 months, 11.5% reported using EDMs less than monthly, 5.3% reported using EDMs approximately monthly, and 4.5% reported using EDMs at least weekly. Of men who had used EDMs in the previous 6 months, common reasons cited for its use were to maintain an erection for longer (73.3%), to make it easier to get hard (67.3%), and difficulty in attaining or maintain an erection (53.5%). Use of EDMs in the previous 6 months was associated with illicit drug use and higher rates of sexual risk behavior. Weekly users were more likely to have severe anxiety than less frequent users.nnnCLINICAL TRANSLATIONnThe use of EDMs in the context of intensive sex partying, with the associated potential for increased risk of HIV transmission and illicit drug use, indicates a need to consider the use of EDMs among GBM in HIV prevention and minimizing harm.nnnSTRENGTHS AND LIMITATIONSnThis large-scale study of drug use among GBMs includes comprehensive detailed data on their history of use and rationales for use. Our online methodology potentially decreases social desirability bias in reporting illegal or stigmatized behaviors. This volunteer online convenience sample might not be representative of all GBMs in Australia.nnnCONCLUSIONnGBMs who used an oral EDM in the previous 6 months often used it for recreational purposes, but many of those who used it on a weekly basis also might have used it for therapeutic reasons. GBMs often use EDMs to enhance their sexual experiences often in the context of intensive sex partying (which can include risky sexual behavior). Hammoud MA, Jin F, Lea T, etxa0al.

BACKGROUNDnWhile illicit drug use is prevalent among gay and bisexual men (GBM) in Australia, little is known about the factors associated with injecting drug use among GBM.nnnMETHODSnThe Following Lives Undergoing Change (FLUX) study is a national, online prospective observational cohort investigating drug use among Australian GBM. Eligible participants were men living in Australia who were aged 16.5 years or older, identified as gay or bisexual or had sex with at least one man in the last year. We examined baseline data for associations between socio-demographic and behavioural characteristics and recent (last six months) injecting using log-binomial regression.nnnRESULTSnOf 1995 eligible respondents, 206 (10.3%) reported ever injecting drugs and 93 (4.7%) had injected recently, most commonly crystal (91.4%) and speed (9.7%). Among recent injectors, only 16 (17.2%) reported injecting at least weekly; eight (8.6%) reported recent receptive syringe sharing. Self-reported HIV and HCV prevalence was higher among recent injectors than among other participants (HIV: 46.2% vs 5.0%, pu202f<u202f.001; HCV: 16.1% vs. 1.2%, pu202f<u202f.001). Recent injecting was associated with lifetime use of more drug classes (adjusted prevalence ratio (APR)u202f=u202f1.31, 95% Confidence Interval (95%CI) 1.21-1.41), longer time since initiating party drug use (APRu202f=u202f1.02, 95%CI 1.01-1.04), greater numbers of sex partners (2-10 sex partners: APRu202f=u202f3.44, 95%CI 1.45-8.20; >10 sex partners: APRu202f=u202f3.21, 95%CI 1.30-7.92), group sex (APRu202f=u202f1.42, 95%CI 1.05-1.91) and condomless anal intercourse with casual partners (APRu202f=u202f1.81, 95%CI 1.34-2.43) in the last six months.nnnCONCLUSIONSnObserved associations between injecting and sexual risk reflect a strong relationship between these practices among GBM. The intersectionality between injecting drug use and sex partying indicates a need to integrate harm reduction interventions for GBM who inject drugs into sexual health services and targeted sexual health interventions into Needle and Syringe Programs.

Intensive sex partying with gamma-hydroxybutyrate: factors associated with using gamma-hydroxybutyrate for chemsex among Australian gay and bisexual men – results from the Flux Study

Mohamed Hammoud; Adam Bourne; Lisa Maher; Fengyi Jin; Bridget Haire; Toby Lea; Louisa Degenhardt; Jeffrey Grierson; Garrett Prestage

Background Gamma-hydroxybutyrate (GHB) use among gay and bisexual men (GBM) has increased in recent years. It is commonly cited as a sexual-enhancement drug. There is, however, little evidence for factors associated with GHB use or the consequences of its use among GBM.nnnAIMnFactors associated with GHB use, its relationship to sexual risk behaviour, and the contexts, consequences, and motivations for its use were examined.nnnMETHODSnThe Following Lives Undergoing Change (Flux) Study is an online prospective observational study of Australian GBM. At baseline, a total of 3190 GBM provided details about their use of GHB. Data on frequency, methods, pleasures and consequences of their drug use, alongside key demographic variables were collected.nnnRESULTSnMean age was 35.0 years. One in five men (19.5%) had a history of GHB use and 5.4% reported use within the past 6 months, with 2.7% having used it monthly or more frequently. Overdose had been experienced by 14.7%, this was more common among men who used GHB at least monthly. Being HIV-positive, having more gay friends, greater social engagement with gay men who use drugs, a greater number of sexual partners, group sex, and condomless anal intercourse with casual partners were independently associated with GHB use in the past 6 months. Greater social engagement with gay men who use drugs and group sex were independently associated with at least monthly use. More frequent GHB use was independently associated with experiencing overdose among GHB users.nnnCONCLUSIONnMost men used GHB infrequently and it was often used explicitly to enhance sexual experiences, often in the context of intensive sex partying. Men who used GHB frequently, were at greater risk of overdose and other negative health outcomes. GHB use should be considered alongside other drugs that have been implicated in sexual risk behaviour and HIV transmission. Harm-reduction interventions need to consider the particular impact of frequent GHB use.

Systematic review and meta-analysis of diabetes mellitus, cardiovascular and respiratory condition epidemiology in sexual minority women

Catherine Meads; Adam Martin; Jeffrey Grierson; Justin Varney

Objective Sexual minority women (SMW) experience higher chronic disease risk factors than heterosexual counterparts. However, it was unclear if these risks translate into higher physical condition rates. This systematic review evaluates cardiovascular disease (CVD), hypertension, respiratory disease and diabetes mellitus in SMW. Methods A protocol was registered with the Prospero database (CRD42016050299). Included were studies reporting mortality, incidence or prevalence of the above-listed conditions in SMW compared with heterosexual women. Databases (platforms) searched from 2010 to December 2016 were Medline (Ovid), Embase (Elsevier), Cumulative Index to Nursing and Allied Health Literature (Elsevier), PsycINFO (Ovid), Social Policy and Practice (Ovid), Cochrane CENTRAL (Cochrane Library), Science Citation Index (Web of Science), and CAB Abstracts (Ovid). Search terms included Medical Subject Heading (MeSH) terms and text words. Extensive additional searches were conducted in specialist academic journals and websites. Two reviewers checked study eligibility. One independently extracted data and assessed quality, checked by a second reviewer, with disagreements resolved through discussion. The Critical Appraisal Skills Programme cohort checklist was used to assess risk of bias. Meta-analysis was conducted where more than four studies reported the same outcomes, with Comprehensive Meta-Analysis software, using adjusted ORs (AORs) and random-effects models. Heterogeneity was assessed using I2 test. Results Identified were 23 103 citations, 692 full texts screened and 16 studies included (in 18 papers). One reported mortality (from Denmark), none incidence and 15 prevalence (14 USA, 1 Australia). Same-sex cohabiting women had higher mortality rates compared with opposite-sex cohabiting women in CVD (HR=1.37 (95% CI 1.22 to 1.54)) and respiratory disease (HR=2.10 (95% CI 1.74 to 2.53)). AOR meta-analyses of seven studies showed higher asthma rates in lesbians (OR=1.44 (95% CI 1.27 to 1.64), I2=0%) and bisexual women (OR=1.64 (95% CI 1.41 to 1.89), I2=0%) but no differences for CVD (5 studies), hypertension (5 studies) or diabetes mellitus (7 studies). Conclusions These new health estimates require further confirmatory epidemiological studies, and investigation into potential environmental, hormonal, physiological, psychological or genetic causes. This would be supported by routine collection of sexual identity measures in population-level epidemiological surveys.

Age-related prevalence and twelve-month incidence of illicit drug use in a cohort of Australian gay and bisexual men: Results from the Flux Study

Fengyi Jin; Mohamed Hammoud; Lisa Maher; Louisa Degenhardt; Adam Bourne; Toby Lea; Stefanie J. Vaccher; Jeffrey Grierson; Bridget Haire; Garrett Prestage

BACKGROUNDnWe report prevalence and incidence of drug use initiation in Australian gay and bisexual men (GBM) participating in an online cohort study.nnnMETHODSnBetween September 2014 and June 2015, 1,710 GBM were enrolled in the Following Lives Undergoing Change Study and followed-up six monthly. Participants were asked about measures of lifetime use at baseline and recent use (last six months) at all visits. Drug use initiation was defined as men who reported having never used a specific drug prior to baseline and reported recent use at follow-up.nnnRESULTSnParticipants median age was 31 years (range: 16-81). Prevalence of lifetime use was significantly associated with older age for all individual drugs (p trend<0.001), and 84.1% reported lifetime use of any drugs. Just above half (51.9%) reported recent use at baseline, with the majority reporting occasional use (once or twice in the previous six-months). Among men who reported no history of drug use at baseline, drug initiation was highest for amyl nitrite, with an incidence of 10.5 per 100 person-years (95% CI 7.9-13.9), followed by cannabis (7.3 per 100 person-years, 95% CI 5.0-10.6) and ecstasy (5.0 per 100 person-years, 95% CI 3.6-7.0). Younger age was significantly associated with higher incidence of initiation of amyl nitrite, ecstasy, cocaine, ketamine, GHB, and LSD (p trend <0.05 for all).nnnCONCLUSIONnPrevalence of lifetime illicit drug use is lower in younger GBM than in their older counterparts. However, incidence of drug use initiation is high among younger men, providing an opportunity for early intervention.
