Background: Rates of drug and alcohol use are higher among men who have sex with men (MSM) than the general adult male population, and are often associated with increased sexual risk-taking. Objectives: We aim to examine the prevalence of drunk or high sex and their associations with socio-demographic characteristics, gay social network size, and social stress among an online sample of MSM drawn from seven countries. Methods: Sexually-active MSM aged over 18 residing in Australia, Brazil, Canada, South Africa, Thailand, the United Kingdom, or the United States were recruited through Facebook for a quantitative survey (n = 2,403) in 2012. Two outcomes were examined via logistic regression: reporting being buzzed/drunk at last sex, and reporting being high at last sex. Results: Results highlight the role of social stressors in shaping drug use among MSM. Results were context-specific, though commonalities were seen across countries. Being in a male–male sexual relationship was associated with lower odds of being buzzed/drunk at last sex in five countries. Higher scores on measures of external homonegative discrimination and internalized homonegativity were associated with greater odds of reporting being high at last sex in three countries. Conclusions/Importance: Social networks and minority stressors can have significant effects on drug use and sex while drunk or high. This points to the importance of focusing on structural issues when designing interventions for MSM aimed at reducing the transmission of HIV and other STIs. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the article was to investigate recent trends in human immunodeficiency virus (HIV) diagnosis rates among men who have sex with men (MSM) in high-income countries in North America, Western Europe, and Australia., Methods: Data on annual rates of HIV diagnoses among MSM aged 15 to 65 years from 2000 to 2014 were collected from 13 high-income countries. Joinpoint regression software was used to empirically determine country-specific trend periods. Trends in HIV diagnosis rates and in the proportion of diagnoses occurring in young MSM aged 15 to 24 years were analyzed using Poisson regression and log-binomial regression, respectively., Results: Six countries experienced an increasing trend from 2000 to 2007-08 followed by either a stable or declining trend through 2014. Five countries had recently increasing trends, and two countries had one stable trend from 2000 to 2014. All 13 countries experienced increases in the proportion of diagnoses occurring in young MSM., Conclusions: Since 2008, half of the 13 high-income countries examined experienced stable or decreasing trends. Still, some countries continue to experience increasing HIV trends, and young MSM are increasingly represented among new diagnoses. Efforts to support early sexual health promotion, reduce barriers to pre-exposure prophylaxis, and improve care engagement for young MSM are critical to addressing current HIV trends., (Copyright © 2018 Elsevier Inc.

Purpose: To describe and contextualize changes in rates of human immunodeficiency virus (HIV) notifications in men who have sex with men (MSM) in eight countries (Australia, Canada, France, Germany, Netherlands, Spain, United Kingdom, and United States) from 1996-2005., Methods: We analyzed trends in HIV notification rates from 1996-2000 and 2000-2005 by generalized linear regression and estimated annual percentage change (EAPC) in rates of HIV notifications. To interpret trends, we visually examined graphs of primary and secondary syphilis reports among MSM and the prevalence of recent HIV testing., Results: The rate of HIV notifications among MSM declined 5.2% per year (95% confidence interval [CI]: -5.8%, -4.7%) from 1996-2000, and increased 3.3% per year (95% CI: +2.9%,+3.7%) from 2000-2005. During the period of increasing HIV diagnoses, increases in primary and secondary syphilis diagnoses occurred among MSM, but recent HIV testing among MSM did not seem to increase., Conclusions: After declining in the second half of the 1990s, HIV notification rates for MSM increased beginning in 2000. Increased HIV notifications in MSM are not wholly explained by changes in HIV testing. Urgent efforts are required to develop effective HIV prevention interventions for MSM, and implement them broadly in these countries.
