BackgroundSome migrant men who have sex with men (MSM) acquire HIV in France.AimsWe investigated, in migrant MSM receiving HIV care in France, the (i) rate of post-migration-HIV acquisition in France, (ii) delay between arrival and HIV acquisition and (iii) factors affecting HIV acquisition within 1 year after migration.MethodsThis cross-sectional study focused on ≥ 18-year-old MSM born outside France, receiving HIV care in the Paris region. Information on migration history, socioeconomic condition, sexual activity, and health was collected in May 2021-June 2022 through self-administered questionnaires and medical records. Post-migration-HIV-acquisition rate and delay between arrival in France and HIV acquisition were estimated from biographical data and CD4+ T-cell counts. Predictors of HIV acquisition within 1 year after migration were determined using logistic regression.ResultsOverall post-migration HIV-acquisition rate was 61.7% (715/1,159; 95%CI: 61.2-62.2), ranging from 40.5% (95%CI: 39.6-41.6) to 85.4% (95%CI: 83.9-86.0) in participants from Latin America and North Africa. Among post-migration-HIV acquisitions, those within 1 year after migration represented 13.1% overall (95%CI: 11.6-14.6), being highest in participants from sub-Saharan Africa (25%; 95%CI: 21.5-28.3). Participants ≥ 15-years old at migration, with post-migration-acquired HIV, had a 7.5-year median interval from arrival in France to HIV acquisition (interquartile range (IQR): 3.50-14.75). Older age at arrival, region of origin (sub-Saharan Africa and Asia), degree of social disadvantage and numbers of sexual partners were independently associated with acquiring HIV within 1 year in France.ConclusionOur findings may guide HIV prevention policies for most vulnerable migrants to Europe.
在法国，一些与男性发生性关系的移民男性（MSM）感染了艾滋病毒。
我们调查了在法国接受艾滋病毒护理的移民 MSM 中，（i）在法国获得的 HIV 感染后率，（ii）到达和 HIV 感染之间的延迟，以及（iii）在迁移后 1 年内影响 HIV 感染的因素。
这项横断面研究集中在出生于法国以外的年龄在 18 岁及以上、在巴黎地区接受 HIV 护理的 MSM。2021 年 5 月至 2022 年 6 月期间，通过自我管理问卷和医疗记录收集有关移民史、社会经济状况、性行为和健康的信息。根据传记数据和 CD4+T 细胞计数估计感染后 HIV 感染率和到达法国与 HIV 感染之间的延迟。使用逻辑回归确定迁移后 1 年内感染 HIV 的预测因素。
总体感染后 HIV 感染率为 61.7%（715/1,159；95%CI：61.2-62.2），拉丁美洲和北非参与者的范围为 40.5%（95%CI：39.6-41.6）至 85.4%（95%CI：83.9-86.0）。在感染后 HIV 感染中，整体有 13.1%发生在迁移后 1 年内（95%CI：11.6-14.6），撒哈拉以南非洲参与者的比例最高（25%；95%CI：21.5-28.3）。迁移时年龄在 15 岁及以上、感染后 HIV 感染的参与者从到达法国到 HIV 感染的中位间隔为 7.5 年（四分位距（IQR）：3.50-14.75）。到达时年龄较大、原籍国（撒哈拉以南非洲和亚洲）、社会劣势程度和性伴侣人数与在法国 1 年内感染 HIV 独立相关。
我们的研究结果可能为针对欧洲最脆弱移民的 HIV 预防政策提供指导。
