HIV Acquisition and Life Course of Born-abroad Men Who Have Sex With Men Living in Ile-de-France: the GANYMEDE Study

Study Overview
=================
Brief Summary
-----------------
In France, men who have sex with men (MSM) born abroad are the most affected population by HIV, in terms of HIV incidence and prevalence of undiagnosed infections. Close to 50% of born-abroad HIV-infected MSM are living in the region of Ile-de-France, which is the metropolitan area of Paris. Recent European data, not including France, suggest that born-abroad MSM have the highest rate of post-migration HIV acquisition. Many vulnerability factors could explain le burden of HIV in this group of the population. A better understanding of vulnerability factors related to post-migration HIV acquisition should allow to improve HIV prevention and screening strategies among born-abroad MSM living in France. This, in turn, should reduce the burden of HIV in this population in France.

Detailed Description
-----------------
A better understanding of vulnerability factors related to post-migration HIV acquisition should allow to improve HIV prevention and screening strategies among born-abroad MSM living in France. This, in turn, should reduce the burden of HIV in this population in France. Multicenter, cross-sectional, two-year study in the region Ile-de-France. The study is based on the self-completion of a questionnaire, built after an exploratory qualitative study. Constitution of a representative sample of born-abroad HIV-infected MSM from patients followed up for HIV in Paris area. Questionnaires will collect data needed to estimate the post-migration HIV acquisition rates, and will explore contextual and individual factors leading to high exposure to HIV. The participants will complete a questionnaire translated into 5 languages (English, Spanish, Portuguese, Arabic, and Russian) in order to allow almost all of the participants to answer the survey themselves, without assistance. In order to not exclude those who cannot read, or those who do not master any of the 6 languages offered, the questionnaire may be administered with the assistance of a member of the research team of the associated center, including through a telephone interpretation service. A brief eCRF will collect clinical and biological data, and historical viral sequences in associated virology departments, when available.
