Abstract

OBJECTIVES

Sub-Saharan African immigrants are particularly affected by HIV in France, with many acquiring the infection after migration due to precarious circumstances that increase their vulnerability. This study aimed to explore the association between HIV risk perception, knowledge of biomedical HIV prevention methods and sexual behaviours among sub-Saharan African immigrants living in precarious conditions in the greater Paris area.

METHODS

This cross-sectional study analysed data from 614 participants in the MAKASI project, conducted in the greater Paris area (2019-2020). Sociodemographic characteristics, living conditions, knowledge of biomedical HIV prevention methods (postexposure prophylaxis, treatment as prevention and pre-exposure prophylaxis (PrEP)) and sexual behaviours were described by sex using Pearson's χ tests. HIV risk perception, defined as self-reported exposure to HIV comparable to or greater than the general population, was analysed by participant characteristics. A multivariable logistic regression model identified factors associated with HIV risk perception using variables with a significance threshold of 20%.

RESULTS

Most participants (76.5%) were men, with a median age of 34 years (IQR: 29-41) and living in precarious conditions. Forty-one per cent of respondents reported perceiving their HIV exposure risk as comparable to or greater than the general population. Participants aware of PrEP (adjusted OR (aOR) =2.60 (1.17-5.80); p<0.020) and those who had sex with occasional partners without a condom within in the 3 months preceding the survey (aOR=1.89 (1.12-3.18); p<0.017) were more likely to report the same or greater risk of HIV exposure.

CONCLUSIONS

Our findings reveal that PrEP knowledge and sex with occasional partners, particularly participants who did not use condoms, are associated with increased HIV risk perception among sub-Saharan African immigrants. Further research should explore the relationship between PrEP uptake and HIV risk perception in this population.

摘要

目的

在法国，撒哈拉以南非洲移民受艾滋病毒影响尤为严重，许多人在移民后因不稳定的生活状况而感染艾滋病毒，这些状况增加了他们的易感性。本研究旨在探讨生活在大巴黎地区不稳定状况下的撒哈拉以南非洲移民中，艾滋病毒风险认知、生物医学艾滋病毒预防方法知识与性行为之间的关联。

方法

这项横断面研究分析了在大巴黎地区开展的MAKASI项目中614名参与者的数据（2019 - 2020年）。使用Pearson卡方检验按性别描述社会人口学特征、生活条件、生物医学艾滋病毒预防方法知识（暴露后预防、治疗即预防和暴露前预防（PrEP））以及性行为。艾滋病毒风险认知定义为自我报告的与普通人群相当或高于普通人群的艾滋病毒暴露情况，按参与者特征进行分析。多变量逻辑回归模型使用显著性阈值为20%的变量确定与艾滋病毒风险认知相关的因素。

结果

大多数参与者（76.5%）为男性，中位年龄34岁（四分位间距：29 - 41岁），生活状况不稳定。41%的受访者报告认为自己的艾滋病毒暴露风险与普通人群相当或高于普通人群。知晓PrEP的参与者（调整后比值比（aOR）=2.60（1.17 - 5.80）；p<0.020）以及在调查前3个月内与临时伴侣发生无保护性行为的参与者（aOR = 1.89（1.12 - 3.18）；p<0.017）更有可能报告相同或更高的艾滋病毒暴露风险。
