  • Factors influencing PrEP adoption in sexual health clinics within Ontario’s public health system

    Open AccessEmma Nagy, Boris Alvarado et al.ARTICLEFrontiers in Public Health2026

    Introduction: HIV pre-exposure prophylaxis (PrEP) utilization in Ontario is concentrated in two large urban centers, resulting in geographic and structural inequities in access. Little is known about adoption in Public Health Sexual Health Clinics (PHSHCs) or the implementation factors influencing uneven uptake. This study aimed to: (1) assess the extent of PrEP adoption in PHSHCs; (2) identify barriers and facilitators affecting implementation; …

  • Assessing the educational impact of a new HIV PrEP training module among primary care providers in Southeast Ontario

    Open AccessJorge Martinez-Cajas, Jorge Luis Martinez-Cajas et al.ARTICLEAIDS Care2025

    Primary care providers (PCPs) in Canada frequently report limited knowledge and confidence in prescribing HIV pre-exposure prophylaxis (PrEP). To address this gap, we developed and evaluated an online educational module designed to enhance PCPs’ knowledge and PrEP-related clinical skills. Pre- and post-training surveys (n = 38 and n = 20, respectively) showed substantial improvements: understanding of PrEP eligibility increased by 46%; knowledge …

  • Barriers and facilitators to HIV pre-exposure prophylaxis uptake among transgender women in Colombia

    Open AccessMaria Camila-Bolívar, Sheilla Andrea Gomez-Peñaloza et al.ARTICLEPLOS Global Public Health2023

    Transgender women [TGW] in Colombia are disproportionately affected by HIV due to their low sociodemographic conditions, varied risk behaviours, difficulty accessing health services, and discrimination. Offering pre-exposure prophylaxis [PrEP] as part of a combination of prevention strategies is an appropriate option for this population to reduce their risk of HIV infection. However, little is known about how to implement a PrEP program for TGW i…

  • AC-2020-12-1420.R1 – HIV care providers’ familiarity, concerns, and attitudes about HIV PrEP in Colombia

    Open AccessJorge Martinez-Cajas, Boris Alvarado et al.ARTICLEAIDS Care2022

    In 2019, Colombia approved the combination of tenofovir disoproxil fumarate/emtricitabine for HIV Pre-Exposure Prophylaxis (PrEP). Therefore, we conducted a situational analysis in HIV-care providers to identify barriers and facilitators for PrEP implementation. A survey was applied to a non-probabilistic sample of health care workers of HIV-specialized clinics. We examined PrEP awareness and familiarity, comfort with PrEP-related activities, per…

  • Adaptation and Pilot Evaluation of an Intervention Addressing the Sexual Health Needs of Gay Men Living with HIV Infection in Colombia

    Open AccessBoris Alvarado, Jorge Martinez-Cajas et al.ARTICLEAmerican Journal of Men s Health2021

    Interventions addressing the sexual health need of HIV-positive men who have sex with men (MSM) in Latin America are scarce. We adapted and evaluated GPS, a group-based intervention led by peers, developed using the Information-Motivation-Behavioral (IMB) model and motivational interviewing (MI). We used McKleroy et al framework to culturally adapt GPS to MSM living with HIV infection in Colombia. Then, a one-armed pilot trial examined changes in…

  • El Sonido Musical De Victoria Poleva en Articulación Con La Imagen Fílmica De Andrei Tarkovsky

    Open AccessRicardo Espinoza Lolas, Boris Alvarado et al.ARTICLEMúsica Hodie2018

    El artículo pregunta por la articulación esencial entre el arte de Victoria Poleva y Andrei Tarkovsky. En ambos artistas se da algo único en su mutua diferencia. Tanto en el sonido de Poleva como la imagen de Tarkovsky acontece en un cierto cuerpo y espacio de la inmanencia y la materialidad que nos abre a lo otro. Es una arquitectura del espacio (lo profano se vuelve sacro) y una escultura del tiempo (la eternidad en el instante). Creemos que en…

  • Relationships Between Neighborhood Social Capital and The Occurrence of Outdoor Falls in Canadian Older Adults

    Open AccessAfshin Vafaei, William Pickett et al.ARTICLEJournal of Aging and Health2017Cited by: 1References: 4

  • Life-course social and economic circumstances, gender, and resilience in older adults

    Open AccessSusan P Phillips, MOHAMMAD AUAIS et al.ARTICLESSM - Population Health2016

    Although early socioeconomic adversity is associated with poorer function and health in adulthood, those who are able to adapt positively to such risks and threats develop a resilience that may ameliorate harm. Predictors of resilience have been examined in children, however exploring the relationship between life-course events, lived environments and current resilience among older adults across countries is novel. We specifically studied how chi…

  • Neighbourhood social and built environment factors and falls in community-dwelling canadian older adults

    Open AccessAfshin Vafaei, William Pickett et al.ARTICLESSM - Population Health2016

    Older persons are vulnerable to the ill effects of their social and built environment due to age-related limitations in mobility and bio-psychological vulnerability. Falls are common in older adults and result from complex interactions between individual, social, and contextual determinants. We addressed two methodological issues of neighbourhood-health and social epidemiological studies in this analysis: (1) validity of measures of neighbourhood…

  • Single, Divorced, or Separated? Factors That Impact the Lives of Women Who Are Heads of Household in Lima, Peru

    Open AccessBoris Alvarado, Beatriz Alvarado et al.ARTICLESAGE Open2015

    The rupture of a conjugal relationship has both a positive and negative impact on the lives of immediate family members. Although for many women terminating marriage may signal freedom from an oppressive, even violent conjugal relationship, it is undeniable that this separation also results in strong social pressure and discrimination in certain contexts, a situation which limits the woman’s freedom of action in and outside of the home. The purpo…

  • Early maternal age at first birth is associated with chronic diseases and poor physical performance in older age

    Open AccessCatherine M Pirkle, Boris Alvarado et al.ARTICLEBMC Public Health2014

    This study provides evidence that adolescent childbirth may increase the risk of developing chronic diseases and physical limitations in older age. Results likely reflect both the biological and social consequences of early childbearing and if the observed relationship is causal, it reinforces the importance of providing contraception and sex education to young women, as the consequences of early pregnancy may be life-long

  • Música y sensación sonora

    Open AccessBoris Alvarado, Ricardo Espinoza Lolas et al.ARTICLEHispania Sacra2014

    Lo que busca este artículo es investigar el bello y difícil acto de la sensación sonora de la obra de John Tavener (1944-2013) a la luz de una lógica de la sensación de Gilles Deleuze (1925-1995) y de la fenomenología del cuerpo de Xavie Zubiri (1898-1983). Creemos que con los conceptos acuñados por ambos filósofos pueden dar cuenta de un modo más acabado de ese estilo único de la experiencia sonora en la vibración que propone el arte sacro de la…

  • Income and economic exclusion

    Open AccessEmilie Renahy, Boris Alvarado et al.ARTICLEInternational Journal for Equity…2012

    We explicitly distinguish, both conceptually and empirically, between income and economic exclusion, one of the main dimensions of social exclusion. Our results suggest that the economic exclusion index we use measures additional aspects of material deprivation that are not captured by income, such as the effective hardship or level of economic 'well-being
