Homophobia and health among MSM across Europe
A new open access paper using the pan-European EMIS data shows that country-level stigma may have limited HIV transmission among MSM, but by restricting MSM public visibility, it also reduces their ability to access HIV-prevention services. The findings suggest that MSM in European countries with high levels of homophobia remain vulnerable to HIV infection. Although they have less opportunity to identify as gay or bisexual and contact other MSM, this might change with app-driven contact technologies.
