European Men-Who-Have-Sex-With-Men Internet Survey (EMIS-2024). National Report Switzerland

Résumé fourni par la source

The European MSM Internet Survey (EMIS) is a multi-country, multi-language, anonymous online survey targeting sexual minority populations at increased risk of HIV and STIs, primarily—but not exclusively—men who have sex with men (MSM, cis- and transgender) but also transgender women and non-binary individuals who have sex with men. EMIS provides data to support the planning, monitoring, and evaluation of HIV and sexual health interventions across Europe. EMIS is a collaborative project involving community, academic, and governmental partners across Europe, designed to inform sexual health interventions for MSM. It was conducted in 2010 and 2017 with core funding from the European Union Health Programme. The survey was repeated in 2024 with core funding from the European Centre for Disease Prevention and Control (ECDC) and 12 national governmental partners, including the Swiss AIDS Federation. EMIS-2024 covered 50 countries in the WHO European Region, including Switzerland. The survey was available online in the first half of 2024 in 35 languages simultaneously. EMIS is among the largest multi-country surveys of men who have sex with men conducted to date, in terms of the number of participating countries, languages, respondents, and collaborating partners. A key strength of EMIS is its harmonised design, which enables direct comparison of sexual health indicators across countries. The use of a shared questionnaire, consistent recruitment approach, and simultaneous multi-language implementation provides a rare opportunity to examine geographic variation in morbidities, behaviours, unmet needs, and access to and performance of interventions across Europe and beyond. A central methodological challenge has been to ensure conceptual equivalence of survey items across languages and cultural contexts, ensuring that items capture the same underlying constructs across languages. EMIS has generated a substantial body of scientific publications and has contributed to major international monitoring efforts, including the WHO Key Population Atlas. Its instruments and indicators have been adopted or adapted in other surveys, contributing to the harmonisation of sexual health surveillance among MSM. The data have also supported the development of estimates of MSM population size and distribution, including within-country variation in the concentration of MSM populations.www.emis-project.eu
