BACKGROUND Gay, bisexual and other men who have sex with men (MSM) are disproportionately affected by HIV in Canada. Combination antiretroviral therapy has been shown to dramatically decrease progression to AIDS, premature death and HIV transmission. However, there are no comprehensive data regarding combination antiretroviral therapy outcomes among this(More)
BACKGROUND Youth trauma exposure is associated with syndemic HIV risk. We measured lifetime prevalence, type, and correlates of trauma experience by gender among adolescents living in the HIV hyper-endemic setting of Soweto, South Africa. METHODS Using data from the Botsha Bophelo Adolescent Health Survey (BBAHS), prevalence of "ever" experiencing a(More)
Within HIV-endemic settings, few studies have examined gendered associations between sexual self-efficacy (SSE), one’s confidence or perceived control over sexual behavior, and uptake of HIV prevention behaviors. Using cross-sectional survey data from 417 sexually-experienced adolescents (aged 14–19, median age = 18, 60% female) in Soweto, South Africa, we(More)
PURPOSE We examined adolescents' knowledge regarding the origin of HIV/AIDS and correlates of beliefs surrounding conspiracy theories in Soweto, South Africa. Now, a decade post-AIDS denialism, South Africa has the largest antiretroviral therapy roll-out worldwide. However, conspiracy theories stemming from past AIDS denialism may impact HIV prevention and(More)
OBJECTIVES We sought to compare all-cause mortality of people living with HIV and accessing care in Canada and the UK. METHODS Individuals from the Canadian Observational Cohort (CANOC) collaboration and UK Collaborative HIV Cohort (UK CHIC) study who were aged ≥ 18 years, had initiated antiretroviral therapy (ART) for the first time between 2000 and 2012(More)
BACKGROUND Atazanavir/ritonavir and darunavir/ritonavir are common protease inhibitor-based regimens for treating patients with HIV. Studies comparing these drugs in clinical practice are lacking. METHODS We conducted a retrospective cohort study of antiretroviral naïve participants in the Canadian Observational Cohort (CANOC) collaboration initiating(More)
Sexual self-efficacy (SSE) - one's confidence in their ability to perform given sexual behaviours, has been shown to predict adolescents' HIV-prevention practices (e.g., Condom use). Few studies within sub-Saharan Africa, where HIV incidence and prevalence disproportionately affects young women, have examined gendered differences in SSE. We used(More)
BACKGROUND Combination antiretroviral therapy (cART) has reduced mortality from AIDS-related illnesses and chronic comorbidities have become prevalent among HIV-infected patients. We examined the association between hepatitis C virus (HCV) co-infection and chronic kidney disease (CKD) among patients initiating modern antiretroviral therapy. METHODS Data(More)
