  • Viral suppression by residency status among men living with HIV in the context of the expanded ART policy in Shanghai, China

    Open AccessJoshua B Mendelsohn, Yinzhong Shen et al.ARTICLEPLOS Global Public Health2026

    Access to China’s national free antiretroviral therapy (ART) program was historically restricted to the home province or province of birth (“Hukou”). During the COVID-19 pandemic, Shanghai facilitated access to free ART and supportive services for all Shanghai residents regardless of residency status. Our aim was to study differences in viral suppression according to residency status in Shanghai, China. We conducted a cross-sectional survey with …

  • Characteristics of individuals who received a complete, 2-dose mpox vaccine regimen as part of the public health response to the mpox epidemic in Ontario, Canada

    Open AccessRamandip Grewal, Cindy Lau et al.ARTICLEPLOS Global Public Health2025

    In May 2022, an outbreak of mpox emerged in Canada. In June 2022, the province of Ontario began offering first doses of a 2-dose regimen of Modified Vaccinia Ankara–Bavaria Nordic (MVA-BN) to those at high risk of exposure. Second doses became available in September 2022. To help increase dose 2 access and uptake, we sought to understand how individuals who received 2 doses differed from those who received only 1 dose. We conducted a cross-sectio…

    Open AccessMelissa Perri, Ayu Pinky Hapsari et al.ARTICLEAIDS Care2024

    Unemployment is more common among people living with HIV (PLWH) compared to the general population. PLWH who are employed have better physical and mental health outcomes compared to unemployed PLWH. The main objective of this mixed-methods study was to conduct a program evaluation of Employment Action (EACT), a community-based program that assists PLWH in Toronto, Ontario, Canada to maintain meaningful employment. We extracted quantitative data f…

  • Disclosure of HIV-serodiscordant relationships and association with viral suppression

    Open AccessJoshua B Mendelsohn, Liviana Calzavara et al.ARTICLEAIDS Care2023

    BACKGROUND: Little is known about the effects of disclosure of HIV-serodiscordant relationships on clinical outcomes. We aimed to evaluate the effect of relationship disclosure on HIV viral suppression, and hypothesized that disclosure by HIV-positive and HIV-negative partners would be associated with viral suppression in the HIV-positive partner. METHODS: We conducted a Canadian national online and telephone-administered survey of HIV-positive a…

  • Understanding Covid-19 Vaccine Confidence in People Living with HIV

    Open AccessCecilia T Costiniuk, Joel Singer et al.ARTICLEAIDS and Behavior2023

    Understanding the roots of Covid-19 vaccine hesitancy in at-risk groups, such as persons living with HIV (PLWH), is of utmost importance. We developed a modified Vaccine Hesitancy Scale (VHS) questionnaire using items from the National Advisory Committee on Immunization Acceptability Matrix. To examine factors associated with receiving COVID-19 vaccine and the link between vaccine attitudes and beliefs with vaccine behavior, PLWH were recruited v…

  • Social capital and HIV-serodiscordance

    Open AccessJames Iveniuk, Liviana Calzavara et al.ARTICLESSM - Population Health2022

    As people living with HIV are living longer lives, they have a correspondingly greater opportunity to enjoy long-term romantic and sexual partnerships, including with persons who do not live with HIV ("serodiscordant" relationships). In these dyads, asymmetries may emerge in access to social resources between partners. In this paper we examined how serodiscordant couples access informal (interpersonal, such as family and friends) and formal (prac…

  • A national recruitment strategy for HIV-serodiscordant partners living in Canada for the Positive Plus One study

    Open AccessMin Xi, Sandra Bullock et al.ARTICLEBMC Public Health2022

    Our findings provide important new information on and support the use of a multi-pronged approach to recruit HIV-positive and HIV-negative individuals involved in HIV-serodiscordant relationships in Canada. More creative strategies are needed to help index partners recruit their partner in relationships with lower satisfaction and shorter duration and further minimize the risk of "happy couple" bias

  • Influence of previous experience with and beliefs regarding anal cancer screening on willingness to be screened among men living with HIV

    Open AccessJennifer Gillis, Jennifer L Gillis et al.ARTICLEBMC Public Health2022

    Men generally had positive beliefs and were willing to undergo screening, though there were differences by sexual orientation and racial identity. Tailored community-led initiatives could focus on men's understanding of their risk and expectations of anal cancer screening to facilitate participation

  • Help-Seeking to Cope With Experiences of Violence Among Women Living With HIV in Canada

    Open AccessRebecca Gormley, Valerie Nicholson et al.ARTICLEViolence Against Women2021References: 4

    Using baseline data from a community-collaborative cohort of women living with HIV in Canada, we assessed the prevalence and correlates of help-seeking among 1,057 women who reported experiencing violence in adulthood (≥16 years). After violence, 447 (42%) sought help, while 610 (58%) did not. Frequently accessed supports included health care providers ( n = 313, 70%), family/friends ( n = 244, 55%), and non-HIV community organizations ( n = 235,…

  • High retention in HIV care at a tertiary care centre in Toronto, Canada

    Leah Szadkowski, María Luisa Calvache Quesada et al.ARTICLEAIDS Care2018

    Poor retention in HIV care is associated with poor clinical outcomes and mortality. Previous studies of predictors of poor retention have been conducted with a wide variety of populations, using different measures of retention, and occasionally have conflicting results. We studied demographic and psychosocial factors associated with inter-visit interval length in a setting of universal health care and modern cART. Patients attending ≥2 appointmen…

  • Assessing Timely Presentation to Care Among People Diagnosed with HIV During Hospital Admission

    Open AccessClaire Kendall, Esther S Shoemaker et al.ARTICLEAIDS and Behavior2018

    Timely presentation to care for people newly diagnosed with HIV is critical to optimize health outcomes and reduce onward HIV transmission. Studies describing presentation to care following diagnosis during a hospital admission are lacking.

  • Burden and risk factors for gastrointestinal symptom distress in HIV patients in the modern antiretroviral era

    Tyler J O’Neill, Janet Raboud et al.ARTICLEAIDS Care2017

    In the modern antiretroviral (ARV) era, there is limited knowledge about the prevalence and risk factors for HIV patient-reported gastrointestinal (GI) symptoms (diarrhoea/soft stool, nausea/vomiting, bloating/painful abdomen, loss of appetite, and weight loss/wasting) and distress. We prospectively analysed data (2007-2014) on distressing GI symptoms from the Ontario HIV Treatment Network Cohort Study, which follows people attending HIV clinics.…

  • Access and engagement in HIV care among a national cohort of women living with HIV in Canada

    Nadine Kronfli, Ashley Lacombe-Duncan et al.ARTICLEAIDS Care2017

    Attrition along the cascade of HIV care poses significant barriers to attaining the UNAIDS targets of 90-90-90 and achieving optimal treatment outcomes for people living with HIV. Understanding the correlates of attrition is critical and particularly for women living with HIV (WLWH) as gender disparities along the cascade have been found. We measured the proportion of the 1425 WLWH enrolled in the Canadian HIV Women's Sexual and Reproductive Heal…
