  • Who has never tested for HIV following a community-based distribution of HIV self-test kits? Establishing associated predictors in rural Zimbabwe

    Open AccessWellington Murenjekwa, Kudzai Chidhanguro et al.ARTICLEPLOS Global Public Health2025

    In 2023, Zimbabwe attained the 95-95-95 UNAIDS targets. However, some sub-populations are substantially less likely to have tested for HIV. Knowledge of characteristics of these groups is crucial in designing interventions that address their needs. We estimated the prevalence and predictors of “never-having tested for HIV” status following community-based distribution of HIV self-test kits in rural Zimbabwe. We analysed data from a household surv…

  • HIV incidence and prevalence projections for Zimbabwe

    Isaac Taramusi, John Stover et al.ARTICLEAfrican Journal of AIDS Research2025

    Introduction : Understanding how HIV epidemics are likely to behave in the future is key to informing HIV response strategies in low-income countries. Up-to-date HIV epidemiological estimates are important for policy decision- making, but surveillance data can be out of date. This study compared forecasts from HIV epidemiological models. Methods : Five independent modelling groups (EMOD-HIV, Goals, HIV Synthesis, Optima and PopART-IBM) calibrated…

  • Trajectories into gang membership

    Open AccessAndrew Phillips, Andrew N PhillipsARTICLESocial Work/Maatskaplike Werk2025

    Gangs represent a complex phenomenon, emerging in response to social exclusion, limited opportunities and systemic inequalities. In South Africa, gang-related crime is rife, impacting on individuals, families and broader society. Gang practices in the Free State province allegedly incorporate elements of the occult, including devil-worshipping and witchcraft, generating fear within affected communities. These gangs engage in spiritually-motivated…

    Open AccessNadia Hanum, Valentina Cambiano et al.ARTICLEAIDS Care2024

    We described the longitudinal changes in sexual behaviour and associated factors among newly diagnosed with HIV men who have sex with men participating in a prospective observational study from a London HIV clinic (2015–2018). Participants self-completed questionnaires at baseline, months 3 and 12. Information collected included socio-demographic, sexual behaviour, health, lifestyle and social support. Trends in sexual behaviours over one year fo…

  • Impact of the Covid-19 pandemic on the provision and uptake of services for the prevention of mother-to-child transmission of HIV in Zimbabwe

    Open AccessElizabeth Chappell, Anesu Chimwaza et al.ARTICLEPLOS Global Public Health2023

    Zimbabwe is targeting elimination of mother-to-child transmission of HIV by December 2025, however the COVID-19 pandemic challenged health service delivery globally. Monthly aggregated data were extracted from DHIS-2 for all facilities delivering antenatal care (ANC). ZIMSTAT and Spectrum demographic estimates were used for population-level denominators. Programme indicators are among those in HIV care and population indicators reflect the total …

  • A quantitative assessment of the consistency of projections from five mathematical models of the HIV epidemic in South Africa

    Open AccessHaroon Moolla, Andrew Phillips et al.ARTICLEBMC Public Health2023

    While models produced consistent estimates for several outputs, there are areas of variability that should be investigated. This is important if projections are to be used in subsequent cost-effectiveness studies

  • Modeling Contraception and Pregnancy in Malawi

    Open AccessTrevor Colbourn, Eva Janoušková et al.ARTICLEStudies in Family Planning2023Referências: 13

    Malawi has high unmet need for contraception with a costed national plan to increase contraception use. Estimating how such investments might impact future population size in Malawi can help policymakers understand effects and value of policies to increase contraception uptake. We developed a new model of contraception and pregnancy using individual‐level data capturing complexities of contraception initiation, switching, discontinuation, and fai…

  • Understanding early uptake of PrEP by female sex workers in Zimbabwe

    Joanna Busza, Andrew N Phillips et al.ARTICLEAIDS Care2021

    Female sex workers (FSW) are prioritised for increased access to pre-exposure prophylaxis (PrEP), although rates of uptake remain sub-optimal, particularly across Southern Africa. In the first two years of its availability in Zimbabwe, 37.1% of FSW in trial sites initiated PrEP and received at least one re-supply. We conducted a qualitative study on perceptions of PrEP among 19 early users selected from sites with varying rates of PrEP initiation…

  • Recreational drug use and use of drugs associated with chemsex among HIV-negative and HIV-positive heterosexual men and women attending sexual health and HIV clinics in England

    Open AccessAda Miltz, Ada R Miltz et al.ARTICLEInternational Journal of Drug…2021

    Providers need to be aware of cannabis and cocaine use and its potential link with sexual risk behavior and symptoms of depression and anxiety among heterosexual men and women attending sexual health and HIV clinics

  • Potential effects of disruption to HIV programmes in sub-Saharan Africa caused by Covid-19

    Open AccessBritta L Jewell, Edinah Mudimu et al.ARTICLEThe Lancet HIV2020

    BACKGROUND: The COVID-19 pandemic could lead to disruptions to provision of HIV services for people living with HIV and those at risk of acquiring HIV in sub-Saharan Africa, where UNAIDS estimated that more than two-thirds of the approximately 38 million people living with HIV resided in 2018. We aimed to predict the potential effects of such disruptions on HIV-related deaths and new infections in sub-Saharan Africa. METHODS: In this modelling st…

  • Practical metrics for establishing the health benefits of research to support research prioritisation

    Open AccessBeth Woods, Laëtitia Schmitt et al.ARTICLEBMJ Global Health2020

    INTRODUCTION: We present practical metrics for estimating the expected health benefits of specific research proposals. These can be used by research funders, researchers and healthcare decision-makers within low-income and middle-income countries to support evidence-based research prioritisation. METHODS: The methods require three key assessments: (1) the current level of uncertainty around the endpoints the proposed study will measure; (2) how u…

    Open AccessMarina Daskalopoulou, Alec Rodger et al.ARTICLEAIDS Care2020

    We assessed attitudes to disclosure to new sexual partners and association with sexual behaviours among HIV-diagnosed gay, bisexual, and other men who have sex with men (GBMSM) in the UK Antiretrovirals, Sexual Transmission Risk and Attitudes (ASTRA) study in 2011-12. Among 1373 GBMSM diagnosed with HIV for ≥3 months and reporting sex in the past three months (84% on antiretroviral therapy (ART), 75% viral load (VL) ≤50c/mL), 56.3% reported highe…

  • Exploring Mechanisms of Action

    Open AccessT Charles Witzel, T Witzel et al.ARTICLEInternational Journal of…2020

    SELPHI involves two interventions: (A) It provides one HIV self-testing (HIVST) kit; (B) It offers 3-monthly repeat HIVST kits if participants report ongoing risk. A logic model underpinned by the Behaviour Change Wheel informed the design of the intervention. SELPHI recruited 10,135 cis-men and trans people in England and Wales, all reporting anal sex with a man. This paper explores how the interventions were experienced and the pathways to impa…

  • Outsourcing Empire

    Open AccessAndrew Phillips, Andrew N Phillips et al.BOOKOutsourcing Empire2020Citada por: 33

    How chartered company-states spearheaded European expansion and helped create the world’s first genuinely global order From Spanish conquistadors to British colonialists, the prevailing story of European empire-building has focused on the rival ambitions of competing states. But as Outsourcing Empire shows, from the seventeenth to the twentieth centuries, company-states—not sovereign states—drove European expansion, building the world’s first gen…

  • Risk of HIV transmission through condomless sex in serodifferent gay couples with the HIV-positive partner taking suppressive antiretroviral therapy (PARTNER)

    Open AccessAlec Rodger, Alison J Rodger et al.ARTICLEThe Lancet2019

    BACKGROUND: The level of evidence for HIV transmission risk through condomless sex in serodifferent gay couples with the HIV-positive partner taking virally suppressive antiretroviral therapy (ART) is limited compared with the evidence available for transmission risk in heterosexual couples. The aim of the second phase of the PARTNER study (PARTNER2) was to provide precise estimates of transmission risk in gay serodifferent partnerships. METHODS:…

  • Investigating Conceptual Models for the Relationship Between Depression and Condomless Sex Among Gay, Bisexual, and Other Men Who have Sex with Men

    Open AccessAda Miltz, Alec Rodger et al.ARTICLEAIDS and Behavior2019

    The aim of this study is to investigate five hypothesized mechanisms of causation between depression and condomless sex with ≥ 2 partners (CLS2+) among gay, bisexual, and other men who have sex with men (GBMSM), involving alternative roles of self-efficacy for sexual safety and recreational drug use. Data were from the AURAH cross-sectional study of 1340 GBMSM attending genitourinary medicine clinics in England (2013-2014). Structural equation mo…

  • Changes in chemsex and sexual behaviour over time, among a cohort of MSM in London and Brighton

    Open AccessJohn Sewell, Valentina Cambiano et al.ARTICLEInternational Journal of Drug…2019

    Chemsex and use of two individual chemsex drugs (mephedrone and GHB/GBL) significantly declined over time among individuals in the study, alongside most measures of sexual behaviour with the exception of those related to CLAI. Focusing health promotion and HIV prevention, such as awareness of post-exposure prophylaxis (PEP) and access to pre-exposure prophylaxis (PrEP), on MSM that report chemsex, and in particular problematic chemsex, would be h…

  • Sexual Activity Without Condoms and Risk of HIV Transmission in Serodifferent Couples When the HIV-Positive Partner Is Using Suppressive Antiretroviral Therapy

    Alec Rodger, Alison J Rodger et al.ARTICLEJAMA2016

    IMPORTANCE: A key factor in assessing the effectiveness and cost-effectiveness of antiretroviral therapy (ART) as a prevention strategy is the absolute risk of HIV transmission through condomless sex with suppressed HIV-1 RNA viral load for both anal and vaginal sex. OBJECTIVE: To evaluate the rate of within-couple HIV transmission (heterosexual and men who have sex with men [MSM]) during periods of sex without condoms and when the HIV-positive p…

  • Pre-exposure prophylaxis to prevent the acquisition of HIV-1 infection (PROUD)

    Open AccessSheena McCormack, D Dunn et al.ARTICLEThe Lancet2016

    BACKGROUND: Randomised placebo-controlled trials have shown that daily oral pre-exposure prophylaxis (PrEP) with tenofovir-emtricitabine reduces the risk of HIV infection. However, this benefit could be counteracted by risk compensation in users of PrEP. We did the PROUD study to assess this effect. METHODS: PROUD is an open-label randomised trial done at 13 sexual health clinics in England. We enrolled HIV-negative gay and other men who have sex…

  • Non-Disclosure of HIV Status and Associations with Psychological Factors, ART Non-Adherence, and Viral Load Non-Suppression Among People Living with HIV in the UK

    Open AccessMarina Daskalopoulou, Fiona Lampe et al.ARTICLEAIDS and Behavior2016

    Disclosure of HIV status to family, friends, and a stable partner may be linked to improved health outcomes for people living with HIV. This study assessed whether non-disclosure is associated with psychological symptoms, non-adherence to antiretroviral therapy (ART), and viral load (VL) non-suppression. A total of 3258 HIV-diagnosed individuals in the UK completed the confidential ASTRA study questionnaire (2011-2012). Participants reported whet…

  • Health-related quality-of-life of people with HIV in the era of combination antiretroviral treatment

    Open AccessAlec Miners, Andrew Phillips et al.ARTICLEThe Lancet HIV2014

    BACKGROUND: Combination antiretroviral therapy has substantially increased life-expectancy in people living with HIV, but the effects of chronic infection on health-related quality of life (HRQoL) are unclear. We aimed to compare HRQoL in people with HIV and the general population. METHODS: We merged two UK cross-sectional surveys: the ASTRA study, which recruited participants aged 18 years or older with HIV from eight outpatient clinics in the U…
