Social, sexual and structural factors shaping HIV vulnerability among transgender women in Mali
Transgender women (TGW) in Mali face discrimination and stigma, possibly exacerbating HIV vulnerability and limiting access to health services. We identified HIV vulnerability factors among TGW by exploring perceptions and experiences of TGW from urban, peri-urban and rural areas, and those of community workers, using six focus groups (n = 44) and a data thematic content analysis. The analysis highlighted that TGW’s sexual networks included their…
A qualitative study of healthcare workers’ living and working conditions in rural and urban areas of Senegal in the context of Universal Health Coverage
BACKGROUND: Healthcare delivery in Senegal is hindered by a limited, unequally distributed healthcare workforce, and by inadequate infrastructure which negatively impacts access to quality care and good health outcomes. Despite efforts to improve healthcare delivery through Universal Health Coverage (UHC), progress remains insufficient. We investigated the living and working conditions of Senegalese healthcare workers (HWs), specifically their re…
Factors Associated with Not Seeking Post-exposure Prophylaxis for HIV Among PrEP-Naive Men Who Have Sex with Men
HIV post-exposure prophylaxis (PEP) uptake is low among men who have sex with men (MSM), even among those aware of it. We examined factors associated with not seeking PEP among MSM in the ANRS-PREVENIR cohort who were PrEP-naive at enrollment, aware of PEP, and reported a potential need for it in the previous 12 months. Among 3,193 participants, 632 (19.8%) met these criteria, and 424 (67.1%) did not seek PEP. The most cited reasons were low perc…
High Uptake of HIV Pre-exposure Prophylaxis Among Men Who Have Sex with Men Recruited via Geosocial Networking Applications and Community Outreach in Paris, France
Distribution and determinants of Covid-19 seroprevalence in a hard-to-access health district in Mali
In November 2023, three years after the onset of the pandemic, Mali officially recorded 33,160 confirmed COVID-19 cases and 743 related deaths. Tombouctou health district, following Bamako, the capital city, emerged as the second major hotspot with over 532 confirmed cases. However, these figures likely underestimate the true scale of the epidemic due to limited healthcare access and diagnostic capacity. This study aimed to describe the early tra…
Trajectories of Chemsex Engagement Across Time Among PrEP-Using Men Who Have Sex with Men
Objectives To identify trajectories of chemsex engagement and their evolution across time among men who have sex with men (MSM) and the associated factors.Methods Among 2518 PrEP-using MSM in the French ANRS- Prévenir cohort, a group-based trajectory model was used to identify trajectories of chemsex engagement. A multivariable model was then used to estimate time-constant factors associated with trajectory membership, and time-varying factors as…
Access to PrEP for cis and transgender women
Background : Pre-exposure prophylaxis (PrEP) is recommended as part of a comprehensive HIV prevention approach, but its uptake among women, particularly those in key populations, remains limited. Methods : A mixed-methods community-based study was conducted in Mali, Mauritius, and Morocco to assess barriers and facilitators to PrEP implementation among cis and transgender women at high risk of HIV infection. Quantitative data collected included d…
The added value of community-based organisations in retaining people living with HIV (PLHIV) in the continuum of care in Mali
Peer educators play an essential role in PLHIV (general public and KP) retention in care in Mali in terms of psychosocial and logistical support. The non-judgmental approach of physicians working in CBO is also a major factor in retention
The Effect of Sexual and Gender Minority Violence on Depression, Hazardous Drinking, Condom Use, and HIV Acquisition
A Competing Risks Duration Model to Study PrEP Discontinuation Among MSM in France
Men Who Have Sex with Both Men and Women in West Africa
HIV is highly prevalent in men who have sex with men (MSM) in West Africa. Many MSM in the region also have sex with women (MSMW). Accordingly, they are a potential bridge subpopulation for HIV transmission to women. We aimed to evaluate the proportions and characteristics of West African MSMW at high behavioral risk of acquiring HIV from male partners and transmitting it to female partners (HBRMF). The cohort ANRS-12324 CohMSM Study included 630…
Prevalence of stimulant use and the role of opioid agonist treatment among people who inject drugs in France
INTRODUCTION: The co-use of stimulants and opioids, including opioid agonist treatment (OAT), is very prevalent worldwide. A large body of data exists on the association between stimulant use and its health complications, and on OAT effectiveness among people with opioid use disorder. However, few data exist on stimulant-opioid co-use among people receiving OAT. Using data from the COSINUS cohort study, we investigated the association between the…

Highly precarious general and sexual health conditions of young domestic servants
Most domestic servants (DS) in Mali are very young female migrants living in precarious conditions. We aimed to understand their living and working conditions in relation to their general and sexual health. Seven focus groups (53 participants) were conducted by the DS community-based organization ADDAD. Narratives were thematically analyzed using an inductive method. The dominant emerging theme was DS' strong dependence on their employers. Employ…
Socio-behavioral correlates of pre-exposure prophylaxis use and correct adherence in men who have sex with men in West Africa
Community-based clinic attendance and PE contact outside of scheduled visits were both associated with higher PrEP engagement, but some socially and economically marginalized participants struggled with adherence. As scale-up continues in West Africa, we recommend implementing community-based interventions and providing extra support for vulnerable users to ensure adequate PrEP engagement

Evolution of Condom Use Among a 5-Year Cohort of Female Sex Workers in Zambia
Individual and healthcare supply-related barriers to treatment initiation in HIV-positive patients enrolled in the Cameroonian antiretroviral treatment access programme
Increasing demand for antiretroviral treatment (ART) together with a reduction in international funding during the last decade may jeopardize access to ART. Using data from a cross-sectional survey conducted in 2014 in 19 HIV services in the Centre and Littoral regions in Cameroon, we investigated the role of healthcare supply-related factors in time to ART initiation in HIV-positive patients eligible for ART at HIV diagnosis. HIV service profile…
Impact of HIV risk perception on both pre-exposure prophylaxis and condom use
Risk perception is one of the several important factors impacting sexual health behaviours. This study investigated the evolution of HIV risk perception on pre-exposure prophylaxis adherence and condom use in men who have sex with men at high risk of HIV and associated factors. Group-based trajectory modelling helped in identifying patterns of risk perception, pre-exposure prophylaxis adherence and condom use over time. The association between th…
Loss to follow-up among female sex workers in Zambia
HIV-incidence studies are used to identify at-risk populations for HIV-prevention trials and interventions, but loss to follow-up (LTFU) can bias results if participants who remain differ from those who drop out. We investigated the incidence of and factors associated with LTFU among Zambian female sex workers (FSWs) in an HIV-incidence cohort from 2012 to 2017. Enrolled participants returned at month one, month three and quarterly thereafter. FS…
Changes in Sexual Behaviors in Men Who Have Sex with Men
Sex work among female workers in the traditional mining sector in Mali – results from the ANRS-12339 Sanu Gundo cross-sectional study in 2015
Female sex workers (FSW) in mining sites are considered to be at very high risk of HIV infection. We aimed to characterize FSW at the Kôkôyô artisanal gold mining site in Mali, and identify factors associated with sex work using data from ANRS-12339 Sanu Gundo, a cross-sectional survey conducted in 2015 at the mine by ARCAD-SIDA, a Malian non-governmental organisation. People attending HIV-prevention activities were invited to participate in the …
A generalized additive model to disentangle age and diagnosis-specific cohort effects in psychological and behavioral outcomes in people living with HIV
Psychosocial and behavioral outcomes are complex processes which can be explained in different ways by a combination of the clinical and social contexts which PLWH are exposed to at the time of diagnosis, and by developmental characteristics. A greater understanding of these processes could inform healthcare policy-making for specific HIV generations and different HIV age groups

Health-related quality of life of people living with HIV followed up in hospitals in France
In recent years, France has witnessed both structural changes in the population of people living with HIV and a relative improvement in the social representation of HIV infection. However, potential changes in people's day-to-day experience with HIV have not been documented. We used data from the national surveys ANRS-VESPA (2003) and VESPA2 (2011) to compare the levels and patterns of correlates of health-related quality of life (HRQL) in adult …
Attitudes toward vaccination and the H1N1 vaccine
Factors associated with satisfaction with community-based non-medicalized counseling and testing using HIV rapid tests among MSM in France
The aims of the study were to determine the level of satisfaction of men who have sex with men (MSM) participating in two community-based non-medicalized counseling and testing programs (ANRS-DRAG and ANRS-COM'TEST) offering HIV rapid tests (hereafter CBOffer), and to identify factors associated with satisfaction. Between 2009 and 2011, 436 participants voluntarily benefited from a CBOffer in the two programs. They completed self-administered que…
Heterosexual practices of women and men living with HIV attending hospital outpatient services (ANRS-Vespa2 survey)
HAART has improved the well-being of many people living with HIV (PLWH). This study aimed at (i) comparing heterosexual practices between PLWH and the general population by gender, and (ii) identifying factors associated with sexual practices and at-risk behaviors in the two populations. Self-reported data were collected among PLWH attending hospitals (VESPA2 survey; n = 3022) and the general population (CSF survey; n = 10,280). Significant diffe…
Uptake of PrEP and condom and sexual risk behavior among MSM during the ANRS Ipergay trial
The double-blind phase of the randomized ANRS IPERGAY trial, evaluating sexual activity-based oral HIV pre-exposure prophylaxis (PrEP), was conducted among high-risk men who have sex with men (MSM). Results showed an 86% (95% CI: 40-98) relative reduction in HIV incidence among participants with tenofovir disoproxil fumarate-emtricitabine vs. placebo. The present pooled analysis aimed to analyze (i) participants' adherence to the prescribed treat…

The Creation and Evolution of the Donor Funded Market for Antimalarials and the Growing Role of Southern Firms
Since the early 2000s, the question of access to medicines at affordable prices for Southern populations has appeared as one of the major challenges for the international governance of health. But what is at stake is the creation of market for medicines in the global South, particularly countries in the Sub-Saharan Africa. These markets are new in nature in the sense that they are driven by international organisations where Southern firms, especi…
