Background: Peer support has been extensively studied in specific areas of community-based primary care such as mental health, substance use, HIV, homelessness, and Indigenous health. These programs are often built on the assumption that peers must share similar social identities or lived experiences of disease to be effective. However, it remains unclear how peers can be integrated in general primary care setting that serves people with a diversity of health conditions and social backgrounds.

Background: HIV-related stigma, gender discrimination, and racial discrimination harm mental health and hamper HIV treatment access for women living with HIV. Maladaptive coping strategies, such as substance use, can further worsen HIV treatment outcomes, whereas resilience can improve HIV outcomes. We examined resilience and depression as mediators of the relationship between multiple stigmas and HIV treatment outcomes among women living with HIV.

Engagement along the HIV care cascade in Canada is lower among women compared to men. We used Fuzzy Cognitive Mapping (FCM), a participatory research method, to identify factors influencing satisfaction with HIV care, their causal pathways, and relative importance from the perspective of women living with HIV. Building from a map of factors derived from a mixed-studies review of the literature, 23 women living with HIV in Canada elaborated ten categories influencing their satisfaction with HIV care.

Background: Women with an undetectable viral load can become pregnant and have children with no risk of HIV transmission to their sexual partners and low risk of transmission to their infants. Contemporary pregnancy intentions of women living with HIV in Canada are poorly understood, evidenced by high rates of unintended pregnancy and low uptake of contraceptives.

Methods: We used longitudinal survey data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) to measure and compare pregnancy intentions (Yes vs No vs Unsure) at baseline, 18-months and 36-months follow-up (from 2013 to 2018) among women living with HIV of reproductive age (16-49 years) and potential.

Article Synopsis
  • * The "Women-Centred HIV Care" (WCHC) Model was developed using the knowledge-to-action framework, resembling a house with trauma-aware care as the foundation and person-centred care as the first floor.
  • * The model integrates women’s health, mental health, and peer support, offering a flexible approach to care that can adapt to various settings and delivery methods to meet diverse needs.

Background: Patient and public engagement (PPE) in research is growing internationally, and with it, the interest for its evaluation. In Canada, the Strategy for Patient-Oriented Research has generated national momentum and opportunities for greater PPE in research and health-system transformation. As is the case with most countries, the Canadian research community lacks a common evaluation framework for PPE, thus limiting our capacity to ensure integrity between principles and practices, learn across projects, identify common areas for improvement, and assess the impacts of engagement.

Background: A community-based research (CBR) approach is critical to redressing the exclusion of women-particularly, traditionally marginalized women including those who use substances-from HIV research participation and benefit. However, few studies have articulated their process of involving and engaging peers, particularly within large-scale cohort studies of women living with HIV where gender, cultural and linguistic diversity, HIV stigma, substance use experience, and power inequities must be navigated.

Methods: Through our work on the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS), Canada's largest community-collaborative longitudinal cohort of women living with HIV (n = 1422), we developed a comprehensive, regionally tailored approach for hiring, training, and supporting women living with HIV as Peer Research Associates (PRAs).

Scant research has explored the engagement of transgender (trans) women living with HIV (WLWH) in the HIV care cascade, particularly in universal health care settings like Canada. This convergent parallel, mixed-methods study drew on cross-sectional quantitative data from 50 trans WLWH in the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS) and qualitative semistructured interview data from a subsample of 11 participants. Descriptive analyses were used to describe proportions of trans WLWH at five steps of the HIV care cascade and bivariate analyses to determine associations between hypothesized barriers/facilitators and HIV care cascade outcomes.

Love remains hidden in HIV research in favor of a focus on risk. Among 1424 women living with HIV in Canada, we explored (1) whether eight facets of sex and intimacy (marital status, sexual activity, physical intimacy, emotional closeness, power equity, sexual exclusivity, relationship duration, and couple HIV serostatus) may coalesce into distinct relationship types, and (2) how these relationship types may be linked to love as well as various social, psychological, and structural factors. Five latent classes were identified: no relationship (46.
