RésuméObjective Recent studies highlighted that many HIV-positive migrants in Europe acquired their infections post-migration. However, the timing of these infections is not always known. This study aims to estimate the timing of post-migration HIV acquisition among sub-Saharan migrants in France and to understand the correlates of post-migration infection. Methods Within the PARCOURS retrospective survey conducted in 2012-2013 in 74 healthcare facilities in the Paris region, life-event data were collected among a random sample of 926 patients living with HIV in HIV services and 763 patients undiagnosed with HIV in primary care centres born in sub-Saharan Africa (reference group). Based on previous analysis, we considered the first 6 years in France after migration as a settlement period. Among the persons who acquired HIV after migration, we estimated the proportion of persons infected during settlement (0-6 years after migration) and after settlement (>6 years after migration) by using an algorithm that combines life-event data and a modelisation of CD4(+) T-cell count decline. We then assessed the determinants of HIV acquisition during settlement and after settlement using bivariate logistic regression models. Results Overall, 58% of sub-Saharan migrants who acquired HIV after migration were infected during the first 6 years in France. HIV acquisition during settlement was found to be linked to short/transactional partnerships and lack of a resident permit. 42% of migrants had contracted HIV after settlement. After settlement, HIV acquisition was associated with short/transactional but also with concurrent partnerships and not with social hardship. Conclusion Two profiles of HIV post-migration acquisition emerged. The majority of HIV post-migration acquisition occurs during the settlement period: comprehensive combination prevention programmes among recently arrived migrants are needed. However, long-term migrants are also at risk for HIV through multiple partnerships. Prevention programmes should address the different profiles of migrants at risk for post-migration HIV acquisition.
