Middle-Aged and Older Men Who Have Sex With Men Exhibit Multiple Trajectories With Respect to the Number of Sexual Partners

Background Mathematical models have demonstrated that the majority of gonococcal transmission is from oropharynx to oropharynx (i.e. kissing) among men who have sex with men (MSM). The aim of this study is to investigate the association between the number of partners within specific time periods and gonorrhoea and chlamydia positivity. Methods: This was a retrospective data analysis of MSM attending the Melbourne Sexual Health Centre between 2007 and 2016. Univariable and multivariable logistic regression analyses, with generalised estimating equations (GEE), were performed to determine if the number of partners within specified time periods was associated with site-specific gonorrhoea and chlamydia positivity. Results: There were 45933 consultations which included 15197 MSM. Oropharyngeal gonorrhoea positivity was associated with the number of partners in the past 3 months, but not the number of partners 4–12 months ago; men who had ≥6 partners in the past 3 months had significantly higher odds of acquiring oropharyngeal gonorrhoea (aOR 1.93; 95% CI 1.61–2.31), but this was not the case for men who had ≥6 partners 4–12 months ago. Anorectal gonorrhoea and chlamydia and urethral chlamydia were associated with the number of partners in both time periods after adjusting for age and condom use. Conclusions: The association of oropharyngeal gonorrhoea with the number of recent partners, but not partners from an earlier period, unlike anorectal gonorrhoea and anorectal and urethral chlamydia, could be explained by a shorter duration of oropharyngeal gonococcal infection. Annual screening for gonorrhoea may be insufficient to materially reduce oropharyngeal prevalence.

Spread Of Infection

Gonorrhoea is on the rise in Sweden and in many other European countries. The present report describes and evaluates the gonorrhoea trends in Sweden from 2001 to 2008 when an increase of 32% was reported. Up to 86% of the cases were reported in men, with the highest proportion among heterosexually infected men (41-59% during these years). Heterosexually infected men more often acquired gonorrhoea abroad, especially in Thailand, whereas women and men who have sex with men were more likely to acquire the infection within Sweden. The recent increase in gonorrhoea cases in Sweden is most likely due to adoption of more risky sexual behaviour (e.g. an increase in the number of sexual partners and the number of new/casual sexual partners and/or low use of condoms) in the Swedish population. Further research regarding more effective identification and description of sexual transmission chains and sexual networks is needed in order to follow the spread of infection and to recognise more effective interventions to prevent the spread of gonorrhoea and also other sexually transmitted infections.

Objective Since the recent introduction of preexposure prophylaxis (PrEP), several studies have reported a decrease in the use of condoms and a rise in STIs among users. This rise in risk behavior associated with the advent of PrEP is known as “risk compensation.” The aim of this study is to measure clinical and behavioral changes associated with the introduction of PrEP by analyzing condom use for anal intercourse, number of sexual partners, sexualized drug use and STI incidence. Methods We performed a retrospective descriptive study of PrEP users followed every 3months over a 2-year period spanning 2017–2019 in a referral clinic specializing in STI/HIV in Madrid, Spain. One hundred ten men who have sex with men and transgender women underwent regular screening for STIs and hepatitis C virus (HCV) infection. Sociodemographic, clinical, and behavioral data were gathered for all subjects studied. Results The risk compensation observed in this study consisted primarily of a lower rate of condom use, while the number of sexual partners and recreational drug consumption remained stable. We observed a very high incidence of STIs in this sample, particularly rectal gonorrhea and chlamydia. The factors shown to be independently associated with the presence of an STI on multivariate analysis were age below 30 years and over 10 sexual partners/month. Conclusion The incidence of STI acquisition was higher than expected, indicating a need for strategies to minimize this impact, particularly among younger individuals with a higher number of sexual partners.

Background: Men who have sex with men (MSM) university students were more likely to be infected with HIV than the general population due to various reasons, including having multiple sexual partners, having anal sex without a condom, and using alcohol and drugs. The objective of this study was to investigate the factors associated with multiple sexual partners among MSM university students in northern Thailand. Methods: The participants of this study were 139 MSM university students. The number of sexual partners in the last 12 months was used as the main outcome variable. Information was collected using an online self-administered questionnaire. The number of sexual partners for categories of participants was described as median and interquartile range. Factors that were independently associated with multiple sexual partners were identified using binary logistic regression analysis. Results: Findings showed that seeking sexual partners online (AOR = 1.72; 95% CI 3.10 - 44.29), drinking alcohol within the last 12 months (AOR=9.73; 95% CI 1.38 - 68.47), and having a self-perception of HIV risk (AOR=3.63; 95% CI 1.15 - 11.50) were independently associated with having multiple sexual partners. Conclusion: Health agencies and universities should develop strategies to promote life skills related to sexual responsibility, appropriate use of online media, and reduction of alcohol consumption among MSM university students.

ObjectivesMSM Internet Survey Ireland (MISI) 2015 was an anonymous, self-completed, cross-sectional internet survey assessing sexual behaviours and health needs among men who have sex with men (MSM) in Ireland. We explored factors associated with self-reported STI diagnosis among MSM who were sexually active and had an STI test in the previous year.MethodsWe compared the study population (n=1158; 37% of total population), with the sexually active MISI population not testing for STIs (n=1620; 52% of total population). Within the study population, we identified sociodemographics and sexual behaviours associated with self-reporting STI diagnosis. We used multivariable logistic regression to estimate adjusted odds ratios (aORs).ResultsThe sociodemographics, lifestyle and sexual behaviours of the study population differed significantly from the sexually active MISI population who did not test for STIs. Within the study population, 65% met a sexual partner via geosocial networking smartphone application (GSNa) and 21% self-reported an STI diagnosis in the previous year. On univariable analysis, factors associated with STI diagnosis included: older age, identifying as gay, HIV-positive status, increasing number of sexual partners in the previous year, condomless anal intercourse (CAI) with ≥2 non-steady partners and using GSNa to meet a new sexual partner in the previous year or most recent sexual partner. On multivariable analysis, STI diagnosis was associated with: being aged 25–39 years (aOR 1.8, 95% CI 1.04 to 3.15), CAI with ≥2 non-steady partners (aOR 2.8, 95% CI 1.84 to 4.34), total number of sexual partners (aOR 1.02, 95% CI 1.00 to 1.03) and using GSNa to meet a new sexual partner (aOR 1.95, 95% CI 1.12 to 3.39).ConclusionsSTI diagnosis among MSM testing for STIs is associated with GSNa use, as well as sexual behaviours. GSNas are key settings for STI prevention interventions, which should prioritise men with high numbers of sexual partners and those with multiple CAI partners.

ObjectivesWe evaluated the prevalence of lymphogranuloma venereum (LGV) in anorectal Chlamydia trachomatis-positive French men who have sex with men (MSM) using pre-exposure prophylaxis (PrEP) for HIV. Here, we describe the clinical, biological and behavioural characteristics of these patients.MethodsLaboratories throughout French metropolitan areas performing routine testing for C. trachomatis sent positive anorectal specimens to the National Reference Centre for bacterial STIs for LGV real-time PCR targeting the pmpH gene. Identification of the C. trachomatis genovar was performed by ompA gene sequencing. For each patient, clinical, biological and sexual behaviour data were collected after obtaining written informed consent.ResultsIn 2017, 486 anorectal C. trachomatis-positive specimens from MSM PrEP users were analysed. A strain of genovar L was detected in 91 cases (18.7%). Patients with LGV were significantly more symptomatic, had more sexual partners and more concurrent syphilis compared with their non-LGV counterparts. OmpA gene sequencing, successful in two-thirds of anorectal C. trachomatis-positive specimens, showed that the LGV cases were mainly of variant L2b (n=33), followed by genovar L2 (n=27) and genetic L2b ompA variants (n=16). In 11 cases, the results indicated the occurrence of genetic exchange between L and non-L genovars.ConclusionsLGV was diagnosed in 18.7% of anorectal C. trachomatis-positive specimens from French MSM using PrEP. LGV testing should be carried out for MSM diagnosed with chlamydia and with a large number of sexual partners, high-risk practices and anorectal symptoms. These patients should be presumptively treated as having LGV. This is the first surveillance study of LGV among MSM PrEP users and monitoring should continue.

Older Msm

Middle-aged and older men who have sex with men (MSM) are one of the most underestimated populations with regard to HIV/AIDS infection, despite the worldwide trend of increasing prevalence in recent years. This population also has low rates of testing, although rare studies are done exclusively with middle-aged and older MSM assessing the factors associated with this prevalence. Thus, based on data from an exclusive online survey with middle-aged and older MSM who use geolocation-based dating applications, the purpose of the study was to analyze factors associated with not taking the HIV test among middle-aged (50 years old) and older MSM in Brazil. Using a modification of time-location sampling adapted to virtual reality, 412 volunteers were approached in Grindr®, Hornet®, SCRUFF®, and Daddyhunt®. The multivariate logistic regression model was adopted to produce adjusted odds ratios (ORa), considering a significance level at .05. There were factors associated with not taking the test: being in a relationship (ORa: 0.24; 95% CI [0.10, 0.53]); knowing partner through the applications (ORa: 1.84; 95% CI [1.07, 3.15]); not knowing the serological status (ORa: 5.07; 95% CI [1.88, 13.67]); ejaculating outside of anal cavity (ORa: 1.79; 95% CI [1.04, 3.05]); practicing sex without penetration (ORa: 2.30; 95% CI [1.17, 4.50]); not taking the test as a form of prevention (ORa: 2.83; 95% CI [1.05, 7.68]); and rarely using Viagra in sexual intercourse (ORa: 1.91; 95% CI [1.20, 3.65]). There is a blind spot in the prevalence of HIV testing in older MSM because this population is not being covered by services, which compromises the overall response to HIV, the goals set for universal health coverage.
