The Intersectional Discrimination Index – Revised
The Intersectional Discrimination Index (InDI) includes three measures of anticipated, day-to-day, and major discrimination for intercategorical intersectionality research. Previous studies found that the measures are unidimensional with high loadings, good test-retest reliability, predictive validity, and measurement invariance between Canadian and United States (US) samples. Gaps included the need for cognitive interviewing, reassessing stabili…

Intersectional analysis of suicide risk among transgender and non-binary people
Transgender and non-binary (TNB) people experience high rates of suicidal thoughts and behaviors, but less is known about how suicide risk varies within TNB communities. We investigated variation in suicidality among TNB people across intersecting social identities and positions. This study uses data from Trans PULSE Canada, a 2019 community-based survey of TNB people aged 14+ in Canada. Among 2054 participants aged 16+, conditional inference tre…
“It’s a Big Ordeal”
Objectives: Transgender and gender diverse (TGD) persons are disproportionately affected by sexually transmitted infection (STI) inequities. Research predominantly focuses on HIV disparities among transfeminine persons, whereas non-HIV STIs (e.g., chlamydia) and transmasculine and nonbinary persons are overlooked. Thus, we examined barriers and facilitators to uptake of non-HIV STI testing among TGD persons, inclusive of transmasculine, transfemi…

Access to transition-related health care among transmasculine people in India
Little research has examined the health care experiences of transmasculine people in India, where government initiatives to improve access to transition-related (also called gender-affirmative) care have recently been announced. We draw on data from ‘ Our Health Matters’, a mixed-methods community-based participatory research project, to characterize the transition-related care experiences of transmasculine people in India. Peer researchers condu…
Factors associated with primary healthcare provider access among trans and non-binary immigrants, refugees, and newcomers in Canada
Results may inform settlement organizations of the unique needs and barriers of TNB IRN. Schools and LGBTQ+ organizations may better serve this population - especially those originating from highlighted regions, who live in Quebec or the Prairie provinces, and/or are non-permanent residents - by offering programs that connect them to primary healthcare providers who are competent in cross-cultural trans health

Intersecting Sexual Behavior and Gender Identity Stigmas Among Transgender Women in the United States
Intersecting Inequalities in Access to Justice for Trans and Non-binary Sex Workers in Canada
Introduction In the context of renewed debate about Canada’s “end demand” sex work laws, we took an intersectional approach to characterize experiences with the criminal legal system and perceived access to justice among transgender (trans) and nonbinary sex workers in Canada. Methods The Trans PULSE Canada community-based study collected multimode survey data in fall 2019. Data were cross-stratified by lifetime sex work and sex assigned at birth…

Gender affirming hormone therapy dosing behaviors among transgender and nonbinary adults
Gender-affirming hormones have been shown to improve psychological functioning and quality of life among transgender and nonbinary (trans) people, yet, scant research exists regarding whether and why individuals take more or less hormones than prescribed. Drawing on survey data from 379 trans people who were prescribed hormones, we utilized multivariable logistic regression models to identify factors associated with hormone-dosing behaviors and c…

Impacts of Covid-19 on trans and non-binary people in Canada
Our findings highlight the pandemic's systemic impacts on the lives of trans and non-binary people in domains such as healthcare, employment, and housing, and on the social networks of these groups, many of which reflect an exacerbation of pre-existing inequities. Based on our analysis, we recommend that public health researchers, policymakers, and practitioners attend to the structural impacts of the pandemic on these groups as primary sites of …
Affirming and negotiating gender in family and social spaces
17 participants) and 10 in-depth interviews with transmasculine people in Mumbai and Chennai. Data analyses were guided by minority stress theory and the gender affirmation model. Within family, the pressure to conform to assigned gender roles and gender policing usually began in adolescence and increased over time. Some participants left parental homes due to violence. In educational settings, participants described the enforcement of gender-nor…

Methods in HIV-Related Intersectional Stigma Research
Researchers are increasingly recognizing the importance of studying and addressing intersectional stigma within the field of HIV. Yet, researchers have, arguably, struggled to operationalize intersectional stigma. To ensure that future research and methodological innovation is guided by frameworks from which this area of inquiry has arisen, we propose a series of core elements for future HIV-related intersectional stigma research. These core elem…
Methods for analytic intercategorical intersectionality in quantitative research
We describe actual and adjusted intersectional inequalities in psychological distress and decompose them to identify three component effects for each of 11 intersectional comparison groups (e.g., Indigenous SGM), versus the reference intersectional group that experienced the lowest levels of discrimination (white non-SGM). These reflect the expected inequality in outcome: 1) due to membership in the more discriminated-against group, if its member…
The Intersectional Discrimination Index
Final InDI measures include the 9-item InDI-A, 9-item InDI-D, and 13-item InDI-M, for which we have found initial evidence of construct validity and reliability. In combination with sociodemographic information, the InDI measures can be used to evaluate the role of discrimination as a mediator of intersectional health inequalities, and to monitor the prevalence and impacts of discrimination in heterogeneous populations
Sex and Gender Diversity Among Transgender Persons in Ontario, Canada
Recent estimates suggest that as many as 1 in 200 adults may be trans (transgender, transsexual, or transitioned). Knowledge about dimensions of sex and gender in trans populations is crucial to development of inclusive policy, practice, and research, but limited data have been available, particularly from probability samples. The Trans PULSE community-based research project surveyed trans Ontarians (n=433) in 2009-2010 using respondent-driven sa…
Advancing quantitative intersectionality research methods
A range of methods have recently been proposed for incorporating intersectionality theoretical frameworks into quantitative research methodology. We published a pair of articles on methods for intercategorical intersectionality, in which we distinguished analytic from descriptive studies, identified causal mediation decomposition methods as an appropriate strategy for analytic intercategorical intersectionality, and introduced and validated a gro…
Intersecting impacts of transphobia and racism on HIV risk among trans persons of colour in Ontario, Canada
Purpose – Minority stress theory suggests enhanced HIV risk for those experiencing social marginalization, while an intersectionality framework posits that forms of marginalization may interact. The purpose of this paper is to understand how race/ethnicity- and gender-based discrimination may impact HIV risk among transgender or transsexual (trans) people. Design/methodology/approach – The Trans PULSE project – a community-based research study in…
Sexual Health of Trans Men Who Are Gay, Bisexual, or Who Have Sex with Men
Recent reports have addressed the sexual health of female-to-male transgender or transsexual people who are gay, bisexual, and/or have sex with men (trans GB-MSM) using urban convenience samples. The Trans PULSE Project conducted a multimode, respondent-driven sampling survey in Ontario, Canada, in 2009-2010. Weighted estimates were calculated for trans GB-MSM ( n = 173) for sexual orientation, behavior, partners, and HIV-related risk, as well as…

That's a double-edged sword”
Supervised consumption services (SCS) have been integrated into community health centres in Toronto. We draw on qualitative interviews and ethnographic observations to examine the implementation contexts of these SCS. Participants' perspectives on the integration of SCS within CHCs were mixed. Some participants identified the benefits of integrated SCS such as convenience and access to other health and social services. However, others identified …
Disparities in access to family physicians among transgender people in Ontario, Canada
Background: Informed by the Gelberg-Andersen behavioral model for vulnerable populations, this study examined the prevalence of and factors associated with not having a family physician among transgender (trans) people in Ontario, Canada.Methods: Data were drawn from a respondent-driven sampling (RDS) survey of trans Ontarians age 16 and above (n = 433) conducted between 2009 and 2010. All analyses were weighted using RDS II methods. Prevalence r…
Sexual Inactivity Among Transfeminine Persons
Sexual health research with transfeminine persons (individuals assigned male at birth who identify as female or feminine) has focused on HIV infection and sexual function following medical treatments. Yet, approximately half of transfeminine persons in Ontario, Canada, reported no partnered sex in the previous year. Therefore, we identified sociodemographic, social, and psychosocial factors associated with past-year sexual inactivity among transf…

The Ontario Integrated Supervised Injection Services Cohort Study of People Who Inject Drugs in Toronto, Canada (OiSIS-Toronto)
The Ontario Integrated Supervised Injection Services cohort in Toronto, Canada (OiSIS-Toronto) is an open prospective cohort of people who inject drugs (PWID). OiSIS-Toronto was established to evaluate the impacts of supervised consumption services (SCS) integrated within three community health agencies on health status and service use. The cohort includes PWID who do and do not use SCS, recruited via self-referral, snowball sampling, and communi…
A qualitative exploration of barriers to HIV prevention, treatment and support
Transgender (trans) women experience barriers to access to HIV care, which result in their lower engagement in HIV prevention, treatment and support relative to cisgender people living with HIV. Studies of trans women's barriers to HIV care have predominantly focused on perspectives of trans women, while barriers are most often described at provider, organisation and/or systems levels. Comparing perspectives of trans women and service providers m…

Unique Issues Bisexual People Face in Intimate Relationships
Bisexuality is associated with worse mental health than both heterosexuality and homosexuality on a range of outcomes. Healthy relationships extend a protective effect on one's mental health, but little research has explored the issues faced by bisexuals in developing and maintaining intimate relationships. This study uses qualitative methodology to identify some of these issues. The results show that bisexual people in intimate relationships hav…

Intervenable factors associated with suicide risk in transgender persons
Large effect sizes were observed for this controlled analysis of intervenable factors, suggesting that interventions to increase social inclusion and access to medical transition, and to reduce transphobia, have the potential to contribute to substantial reductions in the extremely high prevalences of suicide ideation and attempts within trans populations. Such interventions at the population level may require policy change
Global Epidemiology of HIV Infection and Related Syndemics Affecting Transgender People
INTRODUCTION: Transgender populations have been underrepresented in HIV epidemiologic studies and consequently in HIV prevention, care, and treatment programs. Since 2012, there has been a dramatic increase in research focused on transgender people. Studies highlight the burden of HIV and risk determinants, including intersecting stigmas, as drivers of syndemics among transgender populations. This review synthesizes the most recent global epidemi…
Transgender-inclusive measures of sex/gender for population surveys
Given that an estimated 0.6% of the U.S. population is transgender (trans) and that large health disparities for this population have been documented, government and research organizations are increasingly expanding measures of sex/gender to be trans inclusive. Options suggested for trans community surveys, such as expansive check-all-that-apply gender identity lists and write-in options that offer maximum flexibility, are generally not appropria…
Barriers and facilitators to HIV and sexually transmitted infections testing for gay, bisexual, and other transgender men who have sex with men
Transgender men who have sex with men (trans MSM) may be at elevated risk for HIV and other sexually transmitted infections (STI), and therefore require access to HIV and STI testing services. However, trans people often face stigma, discrimination, and gaps in provider competence when attempting to access health care and may therefore postpone, avoid, or be refused care. In this context, quantitative data have indicated low access to, and uptake…
Gay, bisexual, and queer trans men navigating sexual fields
Drawing on interviews with 40 gay, bisexual, and queer trans men in Ontario, Canada, we describe understandings of, and strategies for affective and behavioral negotiation within virtual and physical sexual fields in which they might find male sexual partners. Participants drew sharp distinctions between gay and queer sexual fields. Specific websites for seeking sex also emerged as important fields with their own internal logics. Sexual field cho…

Health of transgender men in low-income and middle-income countries
INTRODUCTION: Despite the rapid growth of research on transgender (trans) health globally, the extent of research on trans men and other transmasculine persons assigned the female sex at birth remains unclear. We, therefore, conducted a scoping review on trans men's health in low-income and middle-income countries (LMICs). METHODS: The review included peer-reviewed articles and conference abstracts, and grey literature published from 1 January 19…
