  • Factors Associated with Not Seeking Post-exposure Prophylaxis for HIV Among PrEP-Naive Men Who Have Sex with Men

    Open AccessJuan Camilo Jones, Marie Costa et al.ARTICLEAIDS and Behavior2026

    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…

  • From initial awareness to sustained involvement

    Open AccessMaaike A J Noorman, Kim Romijnders et al.ARTICLEAIDS Care2026

    HIV remains a persistent global health challenge, emphasizing the urgent need for an effective cure. Meaningful engagement of affected communities is essential for advancing HIV cure efforts. Using stage theories of behavior change, this paper investigated engagement as a dynamic process. Engagement was highlighted with five interconnected stages: awareness, perceived relevance, decision-making, participation, and sustained involvement. These sta…

    This study examined the intricate phenomenon of chemsex among men who have sex with men (MSM) in France, by focusing on the perspectives of different stakeholders, namely people with chemsex experience, clinicians, and community health workers . Employing a sociodynamic approach, lexical analysis was used to identify and interpret key themes in participants’ discourses on chemsex, with a view to revealing its multifaceted nature. Our findings hig…

  • Trajectories of Chemsex Engagement Across Time Among PrEP-Using Men Who Have Sex with Men

    Emils Sietins, Luis Sagaon-Teyssier et al.ARTICLEInternational Journal of Sexual…2025

    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…

  • Socioeconomic marginalization, social exclusion, and engagement in transactional sex among transgender women living with HIV

    Raymond Van Huizen, Margot Annequin et al.ARTICLEAIDS Care2025

    Gender affirmation (GAF) is a multidimensional (psychological, social, medical, administrative) social determinant of health for transgender individuals. Transactional sex (TS) is prevalent among transgender women living with HIV (TWLH), who face intersectional discrimination. GAF’s relationship with TS is understudied. ANRS-Trans&HIV(2020–2022) was a French cross-sectional, community-based, life-event study of TWLH. We used clustering analyses t…

  • Impact of Covid-19 Pandemic on Men Who Have Sex With Men That Practice Chemsex in France

    Open AccessP Roux, Cécile Donadille et al.ARTICLEAmerican Journal of Men s Health2022

    Chemsex—the use of drugs in a sexual context—has been associated with more at-risk sexual practices and substance-related complications in men who have sex with men (MSM). To date, no study has focused on the impact of France’s first coronavirus disease 2019 (COVID-19)-related lockdown on the mental health and drug/alcohol use of MSM who practice chemsex. We implemented a web-based survey of 9,488 MSM living in France in June 2020 (after the coun…

  • Impact of HIV risk perception on both pre-exposure prophylaxis and condom use

    Open AccessMarion Di Ciaccio, Luis Sagaon-Teyssier et al.ARTICLEJournal of Health Psychology2021References: 40

    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…

  • Acceptability of HIV cure-related trials

    Marie Préau, Marjolaine Doumergue et al.ARTICLEAIDS Care2018

    Essential HIV cure-related clinical trials (HCRCT) have a potentially high-risk profile in terms of participants' health, which could hinder enrollment by people living with HIV (PLWH) and healthcare professionals (HP). The ANRS-APSEC survey is part of the IAS "Towards an HIV cure" initiative, which promotes multidisciplinary research for a safe, affordable and scalable cure. The study objectives were to understand the psychosocial mechanisms und…

  • The ANRS-Ipergay trial, an opportunity to use qualitative research to understand the perception of the “participant”-physician relationship

    Marion Di Ciaccio, Christel Protière et al.ARTICLEAIDS Care2018

    The ANRS-IPERGAY trial consisted in providing sexual activity-based antiretroviral prophylaxis for HIV prevention (PrEP) with a package of prevention tools (counselling, condoms, HIV and sexually transmitted infections' screening) to highly exposed HIV-negative men who have sex with men (MSM). Few data exist concerning the patient-physician relationship in the particular context of PrEP, where physicians discuss sexual behaviours with MSM who are…

  • How Can Contingent Valuation Inform the Bioethics Debate? Evidence from a Survey on Hereditary Cancers in France

    Christel Protière, Olivier Chanel et al.ARTICLERevue économique2017References: 2

    Les porteurs de la mutation BRCA1/2 ont un risque plus élevé de développer un cancer du sein ou de l’ovaire à un âge plus jeune. Le diagnostic préimplantatoire (DPI) et le diagnostic prénatal (DPN) sont deux des rares options pour éviter de transmettre cette mutation. Afin d’éclairer le débat sur l’autorisation du DPI et du DNP pour les porteurs de cette mutation, les préférences de 460 porteurs sains ont été révélées grâce à une enquête d’évalua…

  • Take the Money and Run? Hypothetical Fee Variations and French GPs’ Labour Supply

    Olivier Chanel, Alain Paraponaris et al.ARTICLERevue économique2017References: 1

    L’article étudie dans quelle mesure l’offre de travail des médecins généralistes français répond aux variations du tarif de consultation, en s’intéressant pour commencer au signe de cette réponse. Le tarif de la consultation présente peu de variabilité empirique ; c’est pourquoi nous nous sommes appuyés sur une enquête d’évaluation contingente qui formulait trois scénarios d’augmentation, répartis de façon aléatoire sur un échantillon représentat…

  • Pas de prix mais un coût ? Évaluation contingente de l'aide informelle apportée aux personnes âgées en perte d'autonomie

    Open AccessBérangère Davin, Alain Paraponaris et al.ARTICLEEconomie et Statistique /…2015

    Le vieillissement de la population confronte les pays qu’il concerne à certains défis, notamment au regard des soins de long-terme. Prendre en charge une personne âgée en perte d’autonomie génère en effet à la fois des coûts publics et privés qui se chiffrent en milliards d’euros chaque année. L’objectif de cette analyse est d’étudier les déterminants du consentement à payer (CAP) des aidants informels pour l’aide qu’ils apportent aux personnes â…

  • Les consentements a payer pour des programmes de prevention sanitaire incluent-ils de l'altruisme

    Olivier Chanel, Stephane Luchini et al.ARTICLERevue économique2004Cited by: 1

    Increasingly, the assessment of health prevention policies is evaluated through willingness to pay (WTP) surveys. When the evaluation deals with policies with a public dimension, the individual's stated WTP can reflect an altruistic component, which may alter the results of the economic valuation. By applying an expected utility framework in a contingent valuation survey on Q fever, we can determine the individuals who integrate an altruistic com…

    L’évaluation de politiques de prévention sanitaire par le recours à des consentements à payer ( cap ) issus d’enquêtes auprès de la population est de plus en plus fréquent. Lorsque ces politiques revêtent une dimension collective, les cap déclarés par les individus peuvent refléter une composante altruiste, ce qui rend problématique le calcul économique. À partir d’une enquête d’évaluation contingente portant sur deux politiques de prévention de …
