EnquĂȘte Rapport au Sexe [report to sex] 2019 (ERAS 2019) was an anonymous, self-administered online cross-sectional survey conducted between February 16, 2019 and March 31, 2019. It aimed to evaluate MSM uptake of different HIV prevention tools (e.g., condoms, post-exposure prophylaxis, PrEP) in France over time.
Participants were recruited via social networks, LGBTQ+ (lesbian, gay, bisexual, transgender, queer/questioning) dating applications and sites, and online dating sites which use affinity questionnaires. Banners were also published via programmatic advertising platforms. Those exposed to the banners were men age 18 years and older who had searched online, browsed web pages, or liked content-related to male-male sexuality. Clicking on these banners directed people to a site dedicated to ERAS 2019, which included information on the survey's objectives, participation conditions, and data confidentiality. The inclusion criteria were that participants had to be male and age 18 years or older.
