Viral suppression by residency status among men living with HIV in the context of the expanded ART policy in Shanghai, China
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 …
“I think it made me a better person”
Purpose Immigrant youth face both unique and disproportionate barriers to sexual health. Targeted sexual health education to redress these disparities requires creative and inclusive approaches that consider personal and community challenges and strengths. This study piloted a novel intervention: SExT: Sex Education by Theatre, a theatre-based, culturally-relevant, participatory action research programme delivered in an immigration destination ne…

Disclosure of HIV-serodiscordant relationships and association with viral suppression
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…
Sex Education by Theatre (SExT)
Despite rising rates of sexually transmitted infections (STIs) and inequitable access to education and services, few studies have addressed the unique sex education needs of newcomer youth in Canada and other increasingly demographically diverse Western countries. This study involved the design, implementation and evaluation of a novel and innovative participatory action research project, SExT: Sex Education by Theatre. SExT is a theatre-based, c…
Social capital and HIV-serodiscordance
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
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

Examining HIV-related stigma among African, Caribbean, and Black church congregants from the Black PRAISE study in Ontario, Canada
316) and linear regressions determined relationships between HIV-related stigma and stigma subdomains with demographics, greater disagreement with same-sex relationships, HIV knowledge, and religiosity. Greater disagreement with same-sex relationships was the only variable associated with the HIV-related stigma scale and all of its subscales. Age, gender, HIV knowledge, religiosity, contact with persons living with HIV, and length of time in Cana…

The Gender Nonconformity Teasing Scale for gay and bisexual men
Childhood Maltreatment, Bullying Victimization, and Psychological Distress Among Gay and Bisexual Men
Sexual minority men report higher psychological distress than heterosexual men, including depression and anxiety. Research suggests that these health disparities may be due to the heightened stressors that gay, lesbian, and bisexual individuals experience. Some of these stressors occur early on in life, such as childhood abuse and bullying, and may include stressors that are topically related to sexual minority status, such as anti-gay bullying a…
Impact evaluation of a community-based intervention to reduce risky sexual behaviour among female sex workers in Shanghai, China
Following a preventive intervention among Shanghai FSWs, our findings demonstrate that a simple, community-based educational intervention improved overall condom use, HIV and STI knowledge, and attitudes in relation to HIV/AIDS. The intervention should be implemented widely after tailoring educational materials regarding condom negotiation with different partner types (i.e., commercial sex clients and primary partners)
Retrospective Reports of Developmental Stressors, Syndemics, and Their Association with Sexual Risk Outcomes Among Gay Men
Gay and bisexual men (GBM) continue to have a disproportionately higher HIV incidence than any other group in Canada and the United States. This study examined how multiple co-occurring psychosocial problems, also known as a syndemic, contribute to high-risk sexual behavior among GBM. It also examined the impact of early life adversity on high-risk sexual behavior as mediated by syndemic severity. A sample of 239 GBM completed self-report questio…

Intimate partner violence is associated with incident HIV infection in women in Uganda
OBJECTIVES: To quantify the association between intimate partner violence (IPV) and incident HIV infection in women in the Rakai Community Cohort Study between 2000 and 2009. DESIGN AND METHODS: Data were from the Rakai Community Cohort Study annual surveys between 2000 and 2009. Longitudinal data analysis was used to estimate the adjusted incidence rate ratio (IRR) of incident HIV associated with IPV in sexually active women aged 15-49 years, us…
Risk factors for intimate partner violence in women in the Rakai Community Cohort Study, Uganda, from 2000 to 2009
Using longitudinal data, this study identified a number of risk factors for IPV. These findings are useful for the development of prevention strategies to prevent and mitigate IPV in women

Prevalence and Predictors of Urethral Chlamydia and Gonorrhea Infection in Male Inmates in an Ontario Correctional Facility
Effect of Early versus Deferred Antiretroviral Therapy for HIV on Survival
BACKGROUND: The optimal time for the initiation of antiretroviral therapy for asymptomatic patients with human immunodeficiency virus (HIV) infection is uncertain. METHODS: We conducted two parallel analyses involving a total of 17,517 asymptomatic patients with HIV infection in the United States and Canada who received medical care during the period from 1996 through 2005. None of the patients had undergone previous antiretroviral therapy. In ea…
Delayed application of condoms with safer and unsafe sex
While condom use remains one of the most effective measures to prevent the sexual transmission of HIV, decreasing attention appears to be given to its importance and techniques of effective use relative to potential biomedical technologies. This paper focuses on delayed condom application (DCA), one practice which has been implicated in HIV transmission among gay and bisexual men. It examines the prevalence of the practice within a gay community …
Accounts of HIV Seroconversion Among Substance-Using Gay and Bisexual Men
Statistical associations between substance use and seroconversion among gay and bisexual men abound. However, these associations often ignore men's own interpretations of their seroconversion. Using in-depth interviews with gay and bisexual men who reported using drugs or alcohol at the time of their seroconversion, we identify how these men explain the events that led to HIV transmission. Whereas a small minority of respondents reported substanc…
Experiences of and responses to HIV among African and Caribbean communities in Toronto, Canada
African and Caribbean communities in Canada and other developed countries are disproportionately affected by HIV/AIDS. This qualitative study of African and Caribbean communities in Toronto sought to understand HIV-related stigma, discrimination, denial and fear, and the effects of multiple intersecting factors that influence responses to the disease, prevention practices and access to treatment and support services. Semi-structured interviews we…
A qualitative study on the initiation into injection drug use
Previous literature has identified several factors associated with the initiation of injection drug use; we add to this literature by focussing on the biological, psychosocial, socio-cultural and socio-structural processes that play a role in injection initiation. We identified three necessary processes. Firstly, one must already have developed a conception of drugs as creating desired effects. Secondly, initiation is born out of a social context…

Sexual risk and HIV-testing behaviour by gay and bisexual men in Canada
Behavioural epidemiology is an important aspect of HIV research, particularly among marginalized populations where measurement of rates of infection have not been conducted. This Canadian study provides a country-wide analysis of the characteristics and behaviours of gay and bisexual men, and examines the influence of geographic, socio-demographic and lifestyle influences on sexual behaviour and test-seeking. A purposive sample of 4,803 men was r…

How Drug using men who have sex with men account for substance use during Sexual Behaviours
Much HIV prevention research ignores the underlying reasons why drug-using men who have sex with men (DU-MSM) use substances during sex. The present study explores DU-MSM descriptions of the relationships among substance use, sex, and risky sex practices. Twenty-seven in-depth qualitative interviews were conducted with sexually active DU-MSM. The research findings illustrate six roles of substances within the sexual lives of DU-MSM: Enhancing the…
Gay and bisexual men's experiences of bathhouse culture and sex
The aim of this study was to describe gay and bisexual men's experiences of bathhouses and their perceptions of HIV risk associated with sex in this context. Face-to-face, semi-structured interviews were conducted with a purposive sample of gay and bisexual men-14 HIV-positive and 9 HIV-negative-who reported ever frequenting a bathhouse. The sample was selected from the Polaris HIV Seroconversion Study, a longitudinal open cohort study of documen…
Psychosocial Impact of Repeat HIV-Negative Testing
Syringe Acquisition, Peer Exchange and HIV Risk
To explore syringe access patterns and implications for HIV prevention programming, data from qualitative interviews (n=120) with injection drug users (IDU) and an evaluation of a satellite syringe-exchange program (SEP) were used. Three patterns were identified: IDUs who stockpile supplies to meet their own needs and to provide secondary distribution to friends and drug-using associates; IDUs who keep a several-days supply of syringes available,…
