Health status of transgender people globally: A systematic review of research on disease burden and correlates.

BACKGROUND AND OBJECTIVES: Transgender and gender diverse (trans) health research has grown rapidly, highlighting the need to characterize the scientific evidence base. We conducted a systematic review of peer-reviewed research on disease burden and correlates in trans adolescents and adults over a 20-month period to identify knowledge gaps and assess methodological characteristics including measurement of gender identity, community engagement, and study quality. DATA SOURCES, ELIGIBILITY CRITERIA, AND SYNTHESIS METHODS: We searched seven databases using terms related to (a) transgender populations and (b) health or disease. Eligible studies were in English, French, or Spanish and reported original quantitative data on mental health or substance use conditions, infectious diseases, or non-communicable conditions in at least 25 trans individuals aged 15+. Quality assessment was performed in duplicate on a 10% sample of articles and findings were summarized using narrative synthesis. RESULTS: The 328 included studies were conducted in 45 countries, with most from North America (54%) and limited research from South Asia (3%), Sub-Saharan Africa (3%), and the Middle East and North Africa (2%). Most studies used cross-sectional designs (73%) and convenience sampling (65%). Only 30% of studies reported any form of community engagement. Mental health and substance use disorders were the most studied area (77% of studies) and non-communicable conditions the least (16%). Available data indicated that trans populations experience high disease burden with considerable heterogeneity within and across settings. Of 39 articles assessed for quality, 80% were rated as fair, 18% as poor, and 3% as good quality. CONCLUSIONS AND IMPLICATIONS: Geographic, gender-specific, and topical gaps remain in trans health, but we found more research from African countries, with transmasculine people, and on non-communicable conditions than previous syntheses. Areas for growth in trans health research include community engagement, non-binary health, chronic and age-related conditions, and health determinants. REGISTRATION: PROSPERO CRD42021234043.

Preventable mortality among sexual minority Canadians.

Background: Epidemiologic studies point to multiple health inequities among sexual minority people, but few studies have examined mortality. Some causes of death are more preventable than others, and access to prevention is theorized to follow patterns of access to social and material resources. The objective of this study is to compare estimates of preventable mortality between sexual minority (SM)-i.e., bisexual, lesbian, gay-and heterosexual adults in Canada. Methods: A population-based retrospective cohort with 442,260 (unweighted N) Canadian adults, ages 18-59 years, was drawn from the Canadian Community Health Survey/Canadian Mortality Database linked database (2003-2017). The Rutstein preventability rating index was used to classify cause-specific mortality (low/high). Longitudinal analyses were conducted using Cox proportional hazards models. Results: SM respondents had higher hazard of all-cause mortality (unadjusted hazard ratio [uHR] 1.28, 95% CI 1.06, 1.55). The uHR increased when the outcome was limited to highly-preventable causes of mortality (uHR 1.43, 95% CI 1.14, 1.80). The uHR further increased in sensitivity analyses using higher thresholds of the Rutstein index. SM respondents had higher hazard of cause-specific mortality for heart disease (uHR 1.53, 95% CI 1.03, 2.29), accidents (uHR 1.97, 95% CI 1.01, 3.86), HIV (uHR 75.69, 95% CI 18.77, 305.20), and suicide (uHR 2.22, 95% CI 0.93, 5.30) but not for cancer (uHR 0.86, 95% CI 0.60, 1.25). The adjusted HR (aHR) for highly-preventable mortality was not attenuated by adjustment for confounders (aHR 1.57, 95% CI 1.20, 2.05) but was reduced by adjustment for hypothesized mediators relating to access to social and material resources (marital status, children, income, education; aHR 1.11, 95% CI 0.78, 1.58). Conclusions: Preventable mortality was elevated for SM Canadians compared to heterosexuals. Early and broad access to sexual minority-affirming primary and preventive healthcare should be expanded.

A Computable Phenotype Model for Classification of Men Who Have Sex With Men Within a Large Linked Database of Laboratory, Surveillance, and Administrative Healthcare Records.

Background: Most public health datasets do not include sexual orientation measures, thereby limiting the availability of data to monitor health disparities, and evaluate tailored interventions. We therefore developed, validated, and applied a novel computable phenotype model to classify men who have sex with men (MSM) using multiple health datasets from British Columbia, Canada, 1990-2015. Methods: Three case surveillance databases, a public health laboratory database, and five administrative health databases were linked and deidentified (BC Hepatitis Testers Cohort), resulting in a retrospective cohort of 727,091 adult men. Known MSM status from the three disease case surveillance databases was used to develop a multivariable model for classifying MSM in the full cohort. Models were selected using "elastic-net" (GLMNet package) in R, and a final model optimized area under the receiver operating characteristics curve. We compared characteristics of known MSM, classified MSM, and classified heterosexual men. Findings: History of gonorrhea and syphilis diagnoses, HIV tests in the past year, history of visit to an identified gay and bisexual men's clinic, and residence in MSM-dense neighborhoods were all positively associated with being MSM. The selected model had sensitivity of 72%, specificity of 94%. Excluding those with known MSM status, a total of 85,521 men (12% of cohort) were classified as MSM. Interpretation: Computable phenotyping is a promising approach for classification of sexual minorities and investigation of health outcomes in the absence of routinely available self-report data.

Perceived Barriers to Mental Health Services Among Canadian Sexual and Gender Minorities with Depression and at Risk of Suicide.

This study examines barriers to mental health services among sexual and gender minorities (SGM) who screened positive for depression and risk of suicide. Data from an online survey of SGM (N = 2778) are analyzed. 37.5% met criteria for depression and 73.6% screened for being at risk of suicide. The most frequently cited barriers to mental health services access were inability to pay (62.3%), insufficient insurance (52.2%), a preference for 'waiting' for the problems to go away (51.5%), discomfort discussing emotions (45.7%), and feeling embarrassed and ashamed about mental health challenges (42.5%). Policy and practices implications of these findings are discussed.

The Need and Desire for Mental Health and Substance Use-Related Services Among Clients of Publicly Funded Sexually Transmitted Infection Clinics in Vancouver, Canada.

CONTEXT: Sexually transmitted infections (STI) and mental health and substance use (MHSU) disorders all occur at elevated rates in sexual and gender minorities. These overlapping epidemics, or syndemics, are exacerbated by challenges these same populations face in accessing sexual/gender minority-affirming services. Many publicly funded STI clinics are a low barrier and provide sexual minority-competent care. These sites therefore may be uniquely situated to address clients' MHSU-related needs. OBJECTIVE: We characterize the need and desire for MHSU services among STI clinic clients. DESIGN, SETTING, PARTICIPANTS: We conducted a waiting room survey at 6 STI clinics in Metro Vancouver, Canada. MAIN OUTCOME MEASURES: We calculated the proportion of clients with self-reported unmet MHSU needs in the previous 12 months and, among these clients, barriers to accessing MHSU services and desire for MHSU services within the STI clinic. We also examined social disparities in barriers to accessing MHSU services. RESULTS: Among 1115 respondents-65% of whom were sexual minorities-39% reported a recent need for MHSU-related care, most frequently in relation to anxiety (29%), depression (26%), substance use (10%), or suicide ideation (7%). Seventy-two percent of this group had not yet talked to a provider about their concern. Common barriers included shame (26%) and inability to afford the service (24%). Eighty-three percent of clients with unmet MHSU needs indicated that they were comfortable discussing MHSU concerns with an STI clinic provider, and 94% expressed desire to receive MHSU assessments, referrals, or counseling in the STI clinic. Sexual and gender minorities and those attending a suburban clinic were more likely to report barriers to accessing MHSU services. CONCLUSIONS: More than a quarter of STI clinic clients report unmet MHSU health care needs; moreover, these clients report high levels of comfort with and desire to discuss MHSU concerns with STI clinic providers. Sexually transmitted infections clinics are thus opportune sites for syndemic service integration.
