  • Intersecting vulnerabilities, diverging pathways

    Open AccessElla Van Landeghem, B Hensen et al.ARTICLESocial Science & Medicine2026

    OBJECTIVE: This study explored how intersecting vulnerability factors reduced migrants' access to HIV Pre-exposure prophylaxis (PrEP) in Belgium, moving beyond single-factor analyses to examine complex, interconnected barriers. METHODS: Drawing on data from a larger study, we conducted a qualitative multi-method study using key informant interviews (n = 8), in-depth interviews with migrant men and a transgender woman, all of whom have sex with me…

  • Determinants of quality of life in people living with HIV and changes over time

    Gert Scheerder, Ella Van Landeghem et al.ARTICLEAIDS Care2026

    With HIV evolving into a chronic disease, attention is shifting to quality of life (QoL) of people living with HIV (PLWH). We analyzed monitoring data on QoL of PLWH followed up at the Antwerp HIV clinic between 2016-2023, using the WHO-QOL-HIV BREF. Using logistic regression, we analyzed associations of QoL after adjusting for covariates. Changes in QoL across repeated measurements were calculated for a standardized period (mean change score per…

  • Subjective meanings of quality of life and related coping mechanisms

    Christiana Nöstlinger, Gert Scheerder et al.ARTICLEAIDS Care2026

    Despite advances in HIV treatment, people living with HIV face intersecting health and social challenges shaping their quality of life (QoL). Little is known about how people living with HIV in Belgium conceptualise their quality QoL, cope with stressors, and experience their HIV care. We conducted 18 purposively sampled in-depth interviews, analysing them inductively using reflexive thematic analysis from an interpretative perspective. Participa…

  • Mortality and barriers to healthcare among people experiencing homelessness in Paris

    Open AccessEveline Cleynen, Brecht Ingelbeen et al.ARTICLEInternational Journal for Equity…2025

    Homelessness is a global problem with significant public health implications. Persons experiencing homelessness (PEH) face poorer health outcomes and elevated risks of premature death compared to the general population. This is also true for PEH in France, despite the country’s system of universal health coverage. This study investigates 10-year mortality patterns among PEH in Paris and barriers to accessing healthcare. Deaths among PEH—including…

  • Social and sexual networks of newly diagnosed people living with HIV

    Open AccessElla Van Landeghem, Charlotte Vanden Bulcke et al.ARTICLEBMC Public Health2025

    This study revealed important differences in the networks of gay-identified MSM, heterosexuals and hetero- and bisexual identified MSM influencing sexual risk taking and prevention behavior. Future prevention initiatives should be inclusive and mainstreamed to ensure to address those who do not identify as belonging established key populations. Awareness of HIV and biomedical prevention should be raised in the general population, providing a base…

  • Sexual satisfaction, an indicator of sexual health and well-being? Insights from STI/HIV prevention research in European men who have sex with men

    Open AccessKarel Blondeel, Massimo Mirandola et al.ARTICLEBMJ Global Health2024

    INTRODUCTION: Although sexual health has been holistically defined to include sexual satisfaction, it has been largely absent in health services and sexual and reproductive health and rights programmes in many parts of the world. We propose sexual satisfaction as a useful indicator, as one of the proxy measures for sexual health and well-being and as a component of well-being in general. METHODS: The Sialon II project is a multicentre biological …

  • PrEP Among Sub-Saharan African Diaspora Communities in Belgium – a Participatory Action Research Study

    Open AccessElla Van Landeghem, Alida Arbier et al.ARTICLEJournal of Community Health2024

    In Belgium, migrants from Sub-Saharan Africa (SSA) accounted for 45% of new heterosexual HIV infections in 2021, while only 1.5% of PrEP starters were of SSA descent. We explored the acceptance of PrEP and barriers towards PrEP uptake and use among SSA migrant and diaspora communities in Belgium using a participatory action research approach. Trained community researchers (CRs), involved in all phases of the study, co-designed and moderated group…

  • Exploring group differences in the response to a sexual risk reduction intervention to prevent hepatitis C virus reinfection in HIV-infected MSM

    Patrizia Künzler-Heule, Alvin J Schmidt et al.ARTICLEAIDS Care2024

    To prevent hepatitis C virus (HCV) reinfection, within the Swiss HCVree Trial, a preventive risk reduction intervention was implemented alongside curative treatment. Formative qualitative research identified three response patterns to the intervention. This mixed-methods study's aim was to cross-validate group differences in (a) the content of sexual risk reduction goals set during intervention and (b) the extent of their behavioural change in co…

  • Local initiative supports case isolation and contact tracing during a Sars-CoV-2 surge in summer 2020

    Open AccessKristien Verdonck, Stefan Morreel et al.ARTICLEFrontiers in Public Health2023

    In Antwerp, Belgium's second largest city, a COVID-19 surge in July 2020 predominantly affected neighborhoods with high ethnic diversity. Local volunteers reacted and set up an initiative to support contact tracing and self-isolation. We describe the origin, implementation, and transfer of this local initiative, based on semi-structured interviews of five key informants and document review. The initiative started in July 2020, when family physici…

    Open AccessOkikiolu Badejo, Christiana Nöstlinger et al.ARTICLEBMJ Global Health2023

    INTRODUCTION: Youth-friendly health service (YFHS) approaches are essential to better outcomes for young people. We evaluated attainment of viral load suppression among young people living with HIV (YPLHIV) enrolled in an HIV treatment programme implementing YFHS models in Nigeria. METHODS: A realist evaluation using qualitative and quantitative programme data from 10 implementing health facilities. We used qualitative information to explore how …

  • Explanatory Models of (Mental) Health Among Sub-Saharan African Migrants in Belgium

    Open AccessHanne Apers, Christiana Nöstlinger et al.ARTICLECulture Medicine and Psychiatry2023

  • Sub-Saharan African communities’ experiences and engagement with Covid-19 and the related control strategies in Antwerp, Belgium

    Open AccessCharles Ddungu, Lazare Manirankunda et al.ARTICLEInternational Journal for Equity…2023

    Pre-existing disparities influenced the perceptions of and attitudes towards COVID-19 and its control strategies among SSA communities. To better design support and control strategies targeted to specific groups, we need to not only involve communities and address their specific needs and concerns, but also build on their strengths and resilience. This will remain important in the context of widening disparities and future epidemics

  • Patterns of PrEP and condom use among PrEP users in Belgium

    Open AccessAnke Rotsaert, Tom Smekens et al.ARTICLEBMC Public Health2023

    Our findings show that there is little variation in PrEP use over time and that PrEP use was associated with sexual behaviours, which could be taken into account when designing tailored PrEP care

  • Insights into barriers and facilitators in PrEP uptake and use among migrant men and transwomen who have sex with men in Belgium

    Open AccessElla Van Landeghem, Stef Dielen et al.ARTICLEBMC Public Health2023

    An interplay of several underlying determinants and barriers impacts on PrEP uptake among migrant men and transwomen who have sex with men, illustrating a social gradient in access to PrEP. We need equitable access to the full spectrum of HIV prevention and care for all priority populations, including undocumented migrants. We recommend social and structural conditions that foster exercising these rights, including adapting PrEP service delivery,…

  • Responding to the information and prevention needs of sub-Saharan African communities in Antwerp at the beginning of the Covid-19 pandemic

    Open AccessCharles Ddungu, Ella Van Landeghem et al.ARTICLEInternational Journal of…2023

    Pre-existing racial and ethnic disparities in health, sustained by complex and intersecting socio-economic and structural inequities have exacerbated during the COVID-19 pandemic. There is limited evidence about how communities have experience the COVID-19 epidemic, and their perception of the causes and effects of COVID-19 related burden. This hinders true engagement with communities and co-creation of comprehensive prevention strategies includi…

  • Increased Anxiety and Depression Among Belgian Sexual Minority Groups During the First Covid-19 Lockdown—Results From an Online Survey

    Open AccessThijs Reyniers, Buffel et al.ARTICLEFrontiers in Public Health2022

    The COVID-19 pandemic most likely had a negative impact on mental health. Sexual minorities are at higher risk for adverse mental outcomes such as depression, anxiety and suicidal ideation. Such mental health disparities may have exacerbated during the COVID-19 pandemic, due to restricted real-life social contact. The study aim was to examine changes in depression, anxiety and suicidal ideation among Belgian sexual minority adults between the per…

  • From Physical Distancing to Social Loneliness among Gay Men and Other Men Having Sex with Men in Belgium

    Open AccessEstrelle Thunnissen, Veerle Buffel et al.ARTICLEInternational Journal of…2022

    Since the start of the SARS-CoV-2 pandemic, levels of loneliness have increased among the general population and especially among sexual minorities, such as gay men and other men who have sex with men, who already experienced more problems with social isolation before the pandemic. We analyzed how the disruption of the social network and social support structures by containment measures impact loneliness among gay and other men having sex with me…

  • Covid-19 as a social disease

    Open AccessChristiana Nöstlinger, Ella Van Landeghem et al.ARTICLEInternational Journal for Equity…2022

    Study participants' narratives showed how coping with and responding to COVID-19 was strongly intertwined with socio-economic and ethnic/racial characteristics. This justifies conceptualizing COVID-19 a social disease. At the same time, communities demonstrated resilience in responding to these structural vulnerabilities. From a health equity perspective, we provide concrete policy recommendations grounded in insights into communities' structural…

  • Putting 2-1-1 into Practice

    Open AccessAnke Rotsaert, Thijs Reyniers et al.ARTICLEAIDS and Behavior2022

  • Process evaluation of a bio-behavioural HIV research combined with prevention among GBMSM in 13 European countries

    Open AccessSonia Maria Ferreira Dias, Ana Gama et al.ARTICLEGlobal Public Health2021

    Comparative European data using Second Generation Surveillance System (SGSS) are scarce among gay, bisexual and other men who have sex with men. This study evaluated the implementation of Sialon II, a bio-behavioural HIV research combined with targeted HIV prevention in 13 European cities conducted in collaboration with community partners. A mixed-methods process evaluation assessed the project's coverage, outputs, quality, challenges and opportu…

  • Stigma Mechanisms and Outcomes among Sub-Saharan African Descendants in Belgium—Contextualizing the HIV Stigma Framework

    Open AccessLazare Manirankunda, Aletha Wallace et al.ARTICLEInternational Journal of…2021

    HIV-related stigma and discrimination are recognized barriers to HIV prevention, testing and treatment among people of Sub-Saharan African descent (SSA) origin living in Belgium, but insights into HIV related-stigma mechanisms and outcomes are lacking for this population with high HIV prevalence. Guided by Earnshaw and Chaudoir's stigma framework (2009), we conducted this qualitative study using 10 focus-groups with 76 SSA community members and 2…

  • Intimate Partners Violence against Women during a Covid-19 Lockdown Period

    Open AccessJohn Ditekemena, John D Ditekemena et al.ARTICLEInternational Journal of…2021

    Intimate Partners' Violence (IPV) is a public health problem with long-lasting mental and physical health consequences for victims and their families. As evidence has been increasing that COVID-19 lockdown measures may exacerbate IPV, our study sought to describe the magnitude of IPV in women and identify associated determinants. An online survey was conducted in the Democratic Republic of Congo (DRC) from 24 August to 8 September 2020. Of the 41…

  • Understanding how communities respond to Covid-19

    Open AccessJef Vanhamel, Marie Meudec et al.ARTICLEInternational Journal for Equity…2021

    The experiences of Orthodox Jewish communities in Antwerp demonstrate a valuable example of a feasible community-centered approach to health emergencies. Increasing the engagement of communities in local decision-making and governance structures remains a key strategy to respond to unmet information and prevention needs

  • Awareness of, Willingness to Take PrEP and Its Actual Use Among Belgian MSM at High Risk of HIV Infection

  • The social meanings of PrEP use - A mixed-method study of PrEP use disclosure in Antwerp and Amsterdam

    Open AccessThijs Reyniers, Hanne M L Zimmermann et al.ARTICLESociology of Health & Illness2021Referências: 54

    Pre-Exposure Prophylaxis (PrEP) is a novel HIV prevention tool. PrEP stigma is a frequently reported barrier, while social disclosure of PrEP use may be an important facilitator. We explored how PrEP users managed PrEP use disclosure using a symbolic interactionist approach. We interviewed 32 participants from two PrEP demonstration projects (Be-PrEP-ared, Antwerp; AMPrEP, Amsterdam). We validated qualitative findings through Be-PrEP-ared questio…
