A descriptive analysis of alcohol behaviors across gender subgroups within a sample of transgender adults

Sex and sobriety: Human brain structure and function in AUD abstinence

Women are drinking alcohol as much as men for the first time in history. Women experience more health-related consequences from alcohol use disorder (AUD), like increased prevalence of alcohol-related cancers, faster progression of alcohol-related liver disease, and greater risk for relapse compared to men. Thus, sex differences in chronic alcohol use pose a substantial public health problem. Despite these evident sex differences, our understanding of how these differences present during alcohol abstinence is limited. Investigations of brain structure and function are therefore critical for disentangling factors that lead to sex differences in AUD abstinence. This review will discuss current human neuroimaging data on sex differences in alcohol abstinence, focusing on structural and functional brain measures. Current structural imaging literature reveals that abstinent men have smaller gray and white matter volume and weaker structural connectivity compared to control men. Interestingly, abstinent women do not show differences in brain structure when compared to controls; instead, abstinent women show a relation between alcohol use and decreased measures of brain structure. Current functional brain studies reveal that abstinent men exhibit greater brain activation and stronger task-based functional connectivity to aversive stimuli than control men, while abstinent women exhibit lesser brain activation and weaker task-based functional connectivity than control women. Together, the current literature suggests that sex differences persist well into alcohol abstinence and impact brain structure and function differently. Understanding how men and women differ during alcohol abstinence can improve our understanding of sex-specific effects of alcohol, which will be critical to augment treatment methods to better serve women.

Gambling Behavior Among LGBTQ + Individuals: The Role of Gender and Gender Identity

While past literature suggests that LGBTQ + individuals may be at a greater risk for gambling related-harms and addiction, few studies have specifically looked at gambling behavior among LGBTQ + persons based on gender and gender identity. A study of LGBTQ + individuals in four U.S. States was conducted to assess differences in gender and gender identity for (1) gambling prevalence; (2) gambling behavior based on type and location; and (3) comorbidity with substance abuse and/or other problematic behaviors. Individuals assigned male at birth had greater prevalence of gambling than those assigned female at birth, regardless of current gender identity. Gender identity, on its own, is only significant for certain types of gambling and in some analysis only when combined with gender assigned at birth. Findings suggest that gender assigned at birth has a stronger relationship with gambling prevalence and behavior than adult gender identity.

Daily and Momentary Associations Between Gender Minority Stress and Resilience With Alcohol Outcomes

BACKGROUND AND PURPOSE

Minority stressors have been linked with alcohol use among transgender and gender diverse (TGD); however, no ecological momentary assessment studies have examined daily links between minority stress and alcohol use specifically among TGD. This study examined gender minority stressors and resilience as predictors of same-day or momentary alcohol-related outcomes. Feasibility and acceptability of procedures were evaluated.

METHODS

Twenty-five TGD adults (mean age = 32.60, SD = 10.82; 88% White) were recruited Canada-wide and participated remotely. They completed 21 days of ecological momentary assessment with daily morning and random surveys (assessing alcohol outcomes, risk processes, gender minority stressors, resilience), and an exit interview eliciting feedback.

RESULTS

Gender minority stress had significant and positive within-person relationships with same-day alcohol use (incidence risk ratio (IRR) = 1.12, 95% confidence interval [CI] [1.02, 1.23]), alcohol-related harms (IRR = 1.14, 95% CI [1.02, 1.28]), and coping motives (IRR = 1.06, 95% CI [1.03, 1.08]), as well as momentary (past 30-min) alcohol craving (IRR = 1.32, 95% CI [1.18, 1.47]), coping motives (IRR = 1.35, 95% CI [1.21, 1.51]), and negative affect (IRR = 1.28, 95% CI [1.20, 1.36]). Gender minority stress indirectly predicted same-day drinking via coping motives (ab = 0.04, 95% CI [0.02, 0.08]). Resilience was positively associated with same-day alcohol use (IRR = 1.25, 95% CI [1.03, 1.51]) but not harms.

CONCLUSIONS

TGD adults may use alcohol to cope with gender minority stress, which can increase the risk for alcohol-related harms. Interventions are needed to eliminate gender minority stressors and support adaptive coping strategies.

Transgender and non-binary people's experiences with alcohol reduction in the UK: A cross-sectional study

INTRODUCTION

Transgender (trans) and non-binary people experience disproportionate harm from alcohol use, have a greater likelihood of developing dependence, and experience exclusion from both clinical and peer-based support systems. This study aimed to understand experiences with and preferences for alcohol reduction support among UK-based transgender and non-binary people.

METHODS

The study team and community stakeholders co-produced a cross-sectional survey and administered it to a purposive sample of trans and non-binary people from 1st February to 31st March 2022. The study recruited participants through social media, mailing lists, blog posts, and news articles. Participants (n = 565) had a lifetime history of alcohol use, were in one of five gender categories, and were classified as people who drink or formerly drank alcohol. Open- and closed-ended questions measured motivations for alcohol reduction and views surrounding various support modalities.

RESULTS

More than 15 % of the sample no longer drink alcohol and reported long-term abstinence, achieved without support, and were motivated by a loss of control over drinking behaviour and a desire to improve both physical and mental health. Mental illness, gender dysphoria, and a culture of alcohol excess were common antecedents of alcohol use. Thirty percent of participants who drink alcohol wanted to reduce their consumption. They suggested that this could be achieved with self-help tools, specialist trans and non-binary or LGBT+ services, access to both gender-affirming medical services, and sober queer social spaces.

CONCLUSIONS

UK-based trans and non-binary people face unique gender minority-related stressors which contribute to patterns of alcohol use that are perceived to be out of control and harmful to health. While many wanted access to self-help tools, there was interest in the availability of specialist alcohol reduction services and more inclusive general services. Conducting needs assessments to inform Needs assessments should inform the development of such services and trans-affirmative training should be mandated for all who provide support with alcohol reduction.

Alarming patterns of moderate and high-risk alcohol use among transgender women in Goiás, Central Brazil

Background

Scant studies have examined alcohol consumption among transgender women in Latin America. This cross-sectional study estimated the prevalence and associated factors of risky alcohol use among transgender women in Goiás, a state located in the center of Brazil.

Methods

Participants were 440 transgender women (median age = 35 years, interquartile range = 9) recruited through respondent-driven sampling. All participants were interviewed about sociodemographic characteristics, violence, and risk behavior. Alcohol use was assessed using the alcohol use disorders identification test (AUDIT). An AUDIT score greater than or equal to eight was considered as risky alcohol consumption. Logistic regression analysis was used to examine predictors of risky alcohol use, and p-values <0.05 were considered significant.

Results

The majority were young, single, sex workers. Most transgender women had used alcohol in the previous year (85.7%), and more than half (56.6%) reported binge drinking and risky alcohol consumption (60.2%). There was a high overlap between sexual behavior, drugs, and alcohol use. Using alcohol during sex (adjusted odds ratio [aOR]: 2.9; 95% confidence interval [CI]: 1.7-4.8), cocaine/crack use (aOR: 2.3; 95% CI: 1.5-3.7) and having a drug user as a sexual partner (aOR: 2.9; 95% CI: 1.5-5.9) were independently associated with risky alcohol consumption.

Conclusion

Alcohol consumption was highly prevalent, and drugs seem to play an important role in risky alcohol consumption among transgender women Goiás. These findings support stakeholders to promote intervention strategies to reduce this pattern of alcohol consumption and reduce the burden of substance use disorders among transgender women.

Group differences in gender expression discrimination and depressive and anxiety symptoms among transgender and gender-expansive adults: The role of gender identity pride

Despite established associations between discrimination and mental health, little research has focused on gender expression discrimination and integrated individual strengths such as transgender and gender-expansive (TGE) identity pride. This study examined the roles of gender expression discrimination and pride in mental health among TGE adults across gender identity, race, and class. A national sample of TGE adults (N = 212) completed online measures assessing gender identity, race, income, gender expression-related discrimination, TGE identity pride, and depression and anxiety symptoms. Gender expression discrimination was positively associated with depressive and anxiety symptoms. Black, Indigenous, People of Color (BIPOC), higher income, transfeminine participants reported more gender expression discrimination. High TGE identity pride buffered the association between gender expression discrimination and depression-most robustly for BIPOC, lower income, transfeminine participants. TGE identity pride may buffer the effects of gender expression discrimination on depression. Intersectionality in case formulation and treatment planning with TGE individuals is vital.

The Mediating Role of Avoidant and Facilitative Coping on the Relation Between Discrimination and Alcohol Use Among Transgender and Gender-Diverse Individuals

Purpose

The motivational model of alcohol use indicates that there is a relation between chronic stress and alcohol use, and that this relation is mediated by substance use to cope. However, this model has not been applied to the experiences of transgender and gender-diverse (TGD) individuals. In response, this study investigated whether facilitative (e.g., active and interpersonal coping) and avoidant (e.g., cognitive avoidance and substance use to cope) coping mediate the relation between discrimination and alcohol use.

Methods

Participants include 496 TGD individuals (97 trans women, 126 trans men, and 273 nonbinary), 18-68 years of age (mean=32.09 and standard deviation=12.47), who completed a survey about health behaviors and stress. An exploratory factor analysis and confirmatory factor analysis of the Brief Coping Orientation to Problems Experienced (COPE) were conducted to determine the coping patterns of TGD individuals and multiple mediation analyses were conducted to examine whether distinct coping strategies mediated the relation between discrimination and alcohol use.

Results

Both facilitative and avoidant coping strategies were significantly related to discrimination; however, only active coping and substance use to cope were related to alcohol use. Mediation results showed that substance use to cope (i.e., an avoidant coping strategy) was the only significant mediator. Descriptive results showed nonsignificant differences between TGD gender identities regarding levels of alcohol use and engagement with coping strategies.

Conclusion

The results indicate a clear need for interventions to reduce utilization of avoidant coping strategies among TGD individuals.

A narrative systematic review of the gender inclusivity of measures of harmful drinking and their psychometric properties among transgender adults

BACKGROUND AND AIMS

Experiencing higher rates of stigma, marginalization and discrimination puts transgender individuals at risk for alcohol use and associated harms. Measures of harmful drinking were designed with cisgender people in mind, and some rely on sex- and gender-based cut-offs. The applicability of these measures for gender diverse samples remains unknown. The present study had two aims: (i) identify gender-non-inclusive language and cut-offs in measures of harmful drinking, and (ii) systematically review research reporting psychometric properties of these measures in transgender individuals.

METHODS

We reviewed 22 measures of harmful drinking for gendered language and sex- and gender-based cut-off values and provided suggestions for revision when warranted. We also conducted a systematic narrative review, including eight eligible studies, summarizing the psychometric properties of measures of harmful drinking in transgender populations.

RESULTS

Six of 22 measures of harmful drinking were not gender inclusive, because of gendered language in the measure itself or use of sex- or gender-based cut-off scores. Only eight published studies reported psychometric data for these measures in transgender people. Apart from in one study, the Alcohol Use Disorders Identification Test (AUDIT) and Alcohol Use Disorders Identification Test Consumption (AUDIT-C) appear reliable for transgender adults (Cronbach's α: AUDIT [0.81-0.87] and AUDIT [0.72-0.8)]). There is initial support for using uniform cut-offs for transgender people for the AUDIT-C (≥3) and binge drinking (≥5 drinks in a sitting).

CONCLUSIONS

Most existing measures of harmful drinking appear to be gender inclusive (containing gender neutral language and uniform cut-off scores across sex and gender groups) and some that are not easily adapted to be gender inclusive.

Correlates of hazardous alcohol drinking among trans and non-binary people in Canada: A community-based cross-sectional study

PURPOSE

Transgender and non-binary people (TGNB) have a higher rate of heavy episodic drinking than cisgender people; however, extant knowledge about predictors of hazardous alcohol drinking (HAD) among different TGNB groups is limited. This study examined predictors of HAD in a national sample of TGNB people in Canada.

METHODS

Logistic regression models were fit to examine the effects of 1) minority stressors and 2) stress-buffering factors on the likelihood of HAD, stratified by gender, among 2324 TGNB individuals from the Trans PULSE Canada survey, a cross-sectional survey conducted in 2019 among trans and non-binary people aged 14+ in Canada.

RESULTS

Almost 17% of participants reported past-year HAD. Lifetime day-to-day and lifetime major discrimination were associated with higher odds of HAD in the full sample [(AOR=1.37, 95% CI: 1.30, 1.44) and (AOR=1.69, 95% CI: 1.55, 1.86) respectively], and across all gender groups. Social support was associated with lower odds of HAD in trans men, non-binary people assigned female at birth (NB-AFAB), and non-binary people assigned male at birth (NB-AMAB) groups, but with higher odds of HAD in the trans women group. Misgendering was associated with lower odds of HAD in trans men and NB-AFAB, but higher odds of HAD in trans women and NB-AMAB. Mixed effects of gender distress, gender positivity, and gender-affirming medical care were also reported across groups.

CONCLUSION

The study provided a more detailed understanding of the predictors of HAD across four TGNB groups. Public health interventions should focus on structural discrimination and social support for TGNB people.

Protocol for a systematic review of substance use and misuse prevalence and associated factors among transgender and non-binary youth living in the USA

BACKGROUND

Transgender and gender non-binary (TNB) youth living in the USA report elevated levels of substance use compared with their cisgender counterparts, with previous literature pointing to minority stressors as some of the factors that could facilitate such elevated levels. Yet, substance use and misuse prevalence and associated modifiable factors among TNB youth are not fully known. The current paper details the protocol for a systematic review aimed at (1) identifying substance use and misuse prevalence among TNB youth (ages <25) and related demographic disparities (based on racial, ethnic and gender identity, and sexual orientation), (2) examining factors associated with substance use and misuse among TNB youth and (3) examining protective factors against substance use and misuse among TNB youth.

METHODS AND ANALYSIS

Systematic searches will be conducted across four databases: PubMed, LGBTQ+ Source, CINAHL and PsycInfo to identify quantitative, qualitative and mixed-methods peer-reviewed research publications. An exhaustive list of keywords and corresponding MeSH (Medical Subject Headings) terms representing the concepts of 'TNB' (the population of interest) and 'substance use and misuse' (outcome) will be employed. Identified records will be initially screened via a review of titles and abstracts. Full text of the remaining records will be reviewed corresponding to the inclusion and exclusion criteria. Extracted data will be synthesised in table and narrative format. A meta-analysis will be considered contingent on the existence of sufficient data. Methodological quality and risk of bias of studies will be assessed.

ETHICS AND DISSEMINATION

This review does not require approval from the Institutional Review Board as it involves no interactions with human subjects. We will disseminate our findings via peer-reviewed manuscripts and academic conference presentations.

Examining Differences in Substance Use Outcomes and Related Correlates among Transfeminine and Transmasculine Adults Using the 2017 New York State Patient Characteristics Survey

Background: Transgender persons in the U.S. experience high levels of violence and discrimination which have been linked to adverse substance use outcomes. Despite transgender women's higher exposure to such deleterious events compared to transgender men, studies have often aggregated both transgender women and men, obfuscating potentially unique differences between these groups. The current study, guided by the Minority Stress Model, examines differences in substance use outcomes and related correlates among transfeminine and transmasculine adults. Methods: A secondary data analysis was conducted using the 2017 Patient Characteristics Survey of public mental health facilities in the state of New York (N = 1387). Controlling for theoretically relevant factors, logistic regression models were estimated to examine differences between transfeminine and transmasculine adults in alcohol-related disorder (ARD) and drug use-related disorder (DURD) diagnoses, and tobacco use. Correlates of substance use disparities were also examined within gender identity groups. Results: Overall, 35% of participants were documented as using tobacco products whereas 14 and 19% were diagnosed with ARDs and DURDs, respectively. Transfeminine participants were 1.44-times more likely to be diagnosed with ARDs relative to transmasculine adults. Compared to transmasculine and White participants, transfeminine and Black participants were 1.64- and 1.59-times more likely to be diagnosed with DURDs. Conclusions: Recognizing the observed higher hazardous substance use risk among transfeminine and Black participants, findings indicate the potential role of minority stress in health outcomes of stigmatized communities. Our findings emphasize the need for identifying prevention and treatment strategies aimed at mitigating the implications of minority stress.

Differences in Alcohol and Other Drug Use and Dependence Between Transgender and Cisgender Participants from the 2018 Global Drug Survey

Purpose: The purpose of this study was to compare five gender groups (cisgender women, cisgender men, transgender women, transgender men, people with nonbinary/other identities) on measures of use of and dependence on seven substances. Methods: A two-stage approach to assessing gender allowed 126,648 participants from the 2018 Global Drug Survey (GDS) to be classified to one of these five gender groups. Participants were asked to disclose use of each substance in the preceding 12 months. The Alcohol Use Disorders Identification Test and the Severity of Dependence Scale were used to assess dependence. Multivariable logistic regression generated odds ratios (ORs) to measure the association between gender and each substance use/dependence outcome, with cisgender women as the reference group. Results: The sample comprised 43,331 cisgender women, 81,607 cisgender men, 215 transgender women, 254 transgender men, and 1241 people with nonbinary/other identities. Relative to cisgender women, nonbinary/other participants reported greater odds of last 12-month use of all substances (adjusted odds ratio [AOR] = 1.66-2.30), except alcohol (lower odds; AOR = 0.42), and greater odds of dependence on cannabis (AOR = 2.39), 3,4-methylenedioxymethamphetamine (AOR = 1.64) and alcohol (AOR = 3.28), adjusting only for age (all p < 0.05). Conclusion: Transgender 2018 GDS respondents, particularly those with nonbinary/other identities, had greater odds of reporting most substance use outcomes than cisgender women. These findings suggest that a nuanced approach to gender reporting in surveys and treatment centers is required to understand the needs of transgender people who use substances.

Under-Representation of Transgender Identities in Research: The Limitations of Traditional Quantitative Survey Data

Purpose

Research indicates that the portrayal and representation of transgender individuals within society, or lack thereof, impact the way in which they are able to reconcile their gender identity. Quantitative research methodology often requires that participants select one identity label from a limited list for each identity characteristic (e.g., race, sexual orientation, and relationship status). The process of choosing from limited items that do not represent one's identities limits our understanding of the nuances of identity and may create minority stress for the participant.

Methods

This study included 325 diverse transgender adults who participated in a national anonymous online survey as part of a broader study focused on minority stress and mental health. Participants answered questions about gender, sexual orientation, relationship status, race, and religion, and were given the option to select multiple response options and to write in additional identities that were not listed.

Results

Descriptive results indicated that 95 unique gender identities written in were not captured by the 14 gender labels provided, over 43% of participants selected multiple sexual orientations, and participants wrote in additional options for every identity variable.

Conclusion

The nuance of transgender identities may not be adequately captured by standard demographic research methodologies and research would benefit from ongoing revision of demographic response options informed by the literature. Through the process of acknowledging and validating less visible identities, transgender individuals will be better represented and understood by researchers.

Substance Use in the Transgender Population: A Meta-Analysis

(1) Background: This meta-analysis aimed to assess the relationship between identifying as transgender and substance use. (2) Methods: We searched for relevant studies in PubMed, Scopus, the Web of Science, and PsycINFO on 21 July 2021. (3) Results: Twenty studies comparing transgender and cisgender people were included in this work, accounting for a total of 2,376,951 participants (18,329 of whom were transgender). These articles included data on current tobacco use, current tobacco use disorder, current alcohol use, current alcohol use disorder, lifetime substance (all) use, current substance use (excluding tobacco and alcohol), current use of specific substances (excluding tobacco and alcohol and including cocaine, amphetamines, methamphetamines, ecstasy, stimulants, heroin, opiates, cannabis, marijuana, LSD, hallucinogens, steroids, inhalants, sedatives, Ritalin or Adderall, diet pills, cold medicine, prescription medications, polysubstance, other club drugs, and other illegal drugs), and current substance use disorder (excluding tobacco and alcohol). We used the ORs and their 95% CIs to state the association between identifying as transgender and those variables. The control reference category used in all cases was cisgender. We employed a random-effects model. Transgender people were more likely to use tobacco (odds ratio (OR) = 1.65; 95% CI [1.37, 1.98]), have used substances throughout their lives (OR = 1.48; 95% CI [1.30, 1.68]), and present current use of specific substances (OR = 1.79; 95% CI [1.54, 2.07]). When current alcohol and substance use in general and tobacco, alcohol, and substance use disorders specifically were considered, the likelihood did not differ from that of cisgender people. (4) Conclusions: The presence of substance use disorders did not differ between transgender and cisgender people. Considering this population as consumers or as addicted may be a prejudice that perpetuates stigma. Nonetheless, transgender people were more likely to use tobacco and other substances, but not alcohol. Hypothetically, this might be an emotional regulation strategy, a maladaptive mechanism for coping with traumatic experiences, or could respond to minority stress, produced by stigma, prejudice, discrimination, and harassment. It is of particular importance to implement policies against discrimination and stigmatisation and to adapt prevention and treatment services so that they are inclusive of the 2SLGBTQIA+ community.

Alcohol and cannabis use during the COVID-19 pandemic among transgender, gender-diverse, and cisgender adults in Canada

BACKGROUND

This study examined whether heavy episodic drinking (HED), cannabis use, and subjective changes in alcohol and cannabis use during the COVID-19 pandemic differ between transgender and gender-diverse (TGD) and cisgender adults.

METHODS

Successive waves of web-based cross-sectional surveys.

SETTING

Canada, May 2020 to March 2021.

PARTICIPANTS

6,016 adults (39 TGD, 2,980 cisgender men, 2,984 cisgender women, and 13 preferred not to answer), aged ≥18 years.

MEASUREMENTS

Measures included self-reported HED (≥5 drinks on one or more occasions in the previous week for TGD and cisgender men and ≥4 for cisgender women) and any cannabis use in the previous week. Subjective changes in alcohol and cannabis use in the past week compared to before the pandemic were measured on a five-point Likert scale (1: much less to 5: much more). Binary and ordinal logistic regressions quantified differences between TGD and cisgender participants in alcohol and cannabis use, controlling for age, ethnoracial background, marital status, education, geographic location, and living arrangement.

RESULTS

Compared to cisgender participants, TGD participants were more likely to use cannabis (adjusted odds ratio (aOR)=3.78, 95%CI: 1.89, 7.53) and to have reported subjective increases in alcohol (adjusted proportional odds ratios (aPOR)= 2.00, 95%CI: 1.01, 3.95) and cannabis use (aPOR=4.56, 95%CI: 2.13, 9.78) relative to before the pandemic. Compared to cisgender women, TGD participants were more likely to use cannabis (aOR=4.43, 95%CI: 2.21, 8.87) and increase their consumption of alcohol (aPOR=2.05, 95%CI: 1.03, 4.05) and cannabis (aPOR=4.71, 95%CI: 2.18, 10.13). Compared to cisgender men, TGD participants were more likely to use cannabis (aOR=3.20, 95%CI: 1.60, 6.41) and increase their use of cannabis (aPOR=4.40, 95%CI: 2.04, 9.49). There were no significant differences in HED between TGD and cisgender participants and in subjective change in alcohol between TGD and cisgender men; however, the odds ratios were greater than one as expected.

CONCLUSIONS

Increased alcohol and cannabis use among TGD populations compared to before the pandemic may lead to increased health disparities. Accordingly, programs targeting the specific needs of TGD individuals should be prioritized.

A scoping review of alcohol, tobacco, and other drug use treatment interventions for sexual and gender minority populations

BACKGROUND

Alcohol, tobacco, and other drug use are among the most prevalent and important health disparities affecting sexual and gender minority (SGM; e.g., lesbian, gay, bisexual, transgender) populations. Although numerous government agencies and health experts have called for substance use intervention studies to address these disparities, such studies continue to be relatively rare.

METHOD

We conducted a scoping review of prevention and drug treatment intervention studies for alcohol, tobacco, and other drug use that were conducted with SGM adults. We searched three databases to identify pertinent English-language, peer-reviewed articles published between 1985 and 2019.

RESULTS

Our search yielded 71 articles. The majority focused on sexual minority men and studied individual or group psychotherapies for alcohol, tobacco, or methamphetamine use.

CONCLUSION

Our findings highlight the need for intervention research focused on sexual minority women and gender minority individuals and on cannabis and opioid use. There is also a need for more research that evaluates dyadic, population-level, and medication interventions.

Trauma and Alcohol Use Among Transgender and Gender Diverse Women: An Examination of the Stress-Buffering Hypothesis of Social Support

Transgender and gender diverse (TGD) women (i.e., individuals who were assigned male at birth and identify as women or trans women) experience trauma at disproportionate rates compared to cisgender populations. While trauma is associated with increased alcohol use among TGD women, research regarding factors that are protective of this association is scant. The stress-buffering hypothesis of social support suggests that perceived social support, defined as the judgment that social network members will be helpful when individuals experience stress, may buffer and reduce the association between trauma symptoms and alcohol use. However, this relationship has not been examined among TGD women. We examined whether perceived social support moderates the association between trauma and alcohol use among 89 TGD women. Exploratory multiple regression analyses provided support for this hypothesis, insofar as trauma symptoms were related to alcohol use by individuals with low, relative to high levels of perceived social support. Exploratory analyses demonstrated that this finding was driven by perceived social support from friends and family. Our results are the first to suggest that social support reduces alcohol use among TGD women and add to the literature on their trauma and alcohol use.

Review: Prevalence of Addictions among Transgender and Gender Diverse Subgroups

We conducted an analysis of the prevalence of substance and behavioral addictions across different transgender and gender diverse (TGD) subgroups. We performed a scoping review using MEDLINE and Google Scholar databases and examined 12 addictions, including alcohol, nicotine, cannabis, illicit drugs, gambling, eating/food, internet, sex, love, exercise, work, and shopping. We presented prevalence rates for each addiction as a function of an individual’s gender identity (stratified into transgender females, transgender males, and gender nonconforming), and used cisgender women and men as reference groups. We included 55 studies in our final analysis, the majority of which investigated substance use disorders among TGD subgroups. Overall findings indicated that substantial differences in substance use exist among US TGD subgroups. There were far fewer publications that examined the prevalence of behavioral addictions across TGD subgroups. However, despite limited research in this area, findings still suggest that notable differences in behavioral addictions may exist between individual TGD subgroups. The conclusions of our review may provide clinicians with a better ability to screen for and treat at-risk individuals within the TGD community.

Using a Comprehensive Proximal Stress Model to Predict Alcohol Use

Purpose: The gender minority stress model has been proposed by researchers to explain the high rates of substance use found within transgender communities, but its explanatory power has never been directly tested. Further, qualitative research has noted that premedically transitioned and nonbinary individuals are more likely to engage in avoidant coping such as drinking to cope. As such, the current study tested the relationship between proximal stress (comprised of internalized transphobia, anticipated stigma, concealment, and gender dysphoria), drinking to cope, and problematic alcohol use. Methods: Transgender and nonbinary participants over the age of 18 (N=297) completed an online survey on alcohol use. To test for differences in drinking to cope across gender identity and medical transition, analysis of variance and independent t-tests were conducted. Further, a structural equation model of proximal stress was developed to test whether drinking to cope mediated the relationship between proximal stress and alcohol use. Results: There were no significant differences across gender identity or medical transition status in severity of drinking to cope. Proximal stress was significantly related to problematic alcohol use and the relationship was explained by an indirect relationship with drinking to cope. Conclusion: Findings from this study suggest that drinking to cope is an important aspect of high rates of alcohol use found in the transgender community. Implications for clinical practice with transgender individuals are discussed.

Prevalence and correlates of substance use among transgender adults: A systematic review

INTRODUCTION

Minority stress theories suggest that high rates of discrimination experienced by transgender people are precipitants of substance use. This risk is likely exacerbated by an inadequate provision of trans-inclusive substance misuse services. However, the exclusion of transgender people from the general substance misuse literature makes it difficult to determine the extent to which transgender status influences substance use. A systematic review was undertaken to better understand the prevalence, patterns and correlates of substance use among this group.

METHODS

In accordance with the PRISMA guidance, a literature search was conducted to 29th May 2019 on PubMed, PsycINFO, Embase and Global Health databases. Primary quantitative studies, published in English, that reported the prevalence, patterns or correlates of substance use by transgender people were included, with no restriction on methodological design.

RESULTS

653 unique records were identified, and 41 studies were included. Half the studies reported on both transgender men and transgender women and half transgender women only. There was high and excess prevalence of substance use among transgender compared with cisgender people, but insufficient evidence to estimate prevalence or quantify the risk for substance use. Correlates of substance use included transphobic discrimination or violence, unemployment and sex work, gender dysphoria, high visual gender non-conformity and intersectional sexual minority status.

CONCLUSIONS

The sparse findings lend support to the minority stress model. However, the overreliance of the literature on disproportionate investigation of transgender women with multiple intersectional disadvantages, means there are significant gaps regarding the wider transgender community. To ensure substance use treatment services are inclusive, gender identity should be recorded and targeted interventions available. Clinicians should be aware of the multiple, complex drivers of substance use and be prepared to ask about substance use and offer support. Given the high prevalence of trauma experienced by transgender people, trauma-informed psychosocial interventions may be useful in the management of problematic substance use in transgender adults.

Assessing gender identity differences in cardiovascular disease in US adults: an analysis of data from the 2014-2017 BRFSS

The purpose of this study was to assess gender identity differences in CVD risk and CVD conditions among adults in the U.S. Using data from the 2014-2017 BRFSS we compared CVD risk and CVD conditions in gender minorities (transgender men, transgender women and gender nonconforming persons) to both cisgender men and women. The sample consisted of 662,903 participants. Transgender women (AOR 1.34, 95% CI 1.05-1.72) and transgender men (AOR 1.54, 95% CI 1.07-2.24) were more likely to be overweight than cisgender women. Compared to cisgender women, transgender women reported higher rates of diabetes (AOR 1.45, 95% CI 1.05-1.99), angina/coronary heart disease (AOR 1.90, 95% CI 1.34-2.68), stroke (AOR 1.88, 95% CI 1.16-3.03), and myocardial infarction (AOR 2.98, 95% CI 2.14-4.17). Gender nonconforming participants (AOR 2.68, 95% CI 1.14-6.30) reported higher odds of myocardial infarction than cisgender women. Transgender women also had higher rates of reporting any CVD than cisgender men (AOR 1.38, 95% CI 1.01-1.88). There is a need to elucidate the cardiovascular effects of minority stressors and gender affirming therapy in this population. More research focused on CVD prevention and management in gender minorities is recommended.

Improving the Gender-Affirmation Process for Transgender and Gender-Nonconforming Individuals: Associations Among Time Since Transition Began, Body Satisfaction, and Sexual Distress

Sexual distress is associated with a variety of negative outcomes. Unique contributors to sexual distress exist among transgender individuals. The current study examined the impacts of gender-affirming interventions (i.e., hormone therapy [HT], gender-affirmation surgery [GAS]) and body satisfaction on sexual distress among 317 transgender adults recruited nationally to participate in an anonymous online survey. As expected, individuals who had received HT and/or GAS reported better body satisfaction compared to those who wanted these interventions but had not yet received them. Sexual distress did not differ by transition status. As hypothesized, time since transition began was positively associated with body satisfaction, and there was an indirect relationship between time since transition began and sexual distress through body satisfaction. These results replicated findings in the extant literature suggesting that body satisfaction is improved by GAS. Furthermore, this was the first study of which we are aware to examine the role of time since transition began with respect to body satisfaction and the resulting impact on sexual distress. Results from this study may have clinical implications that could help improve the gender-affirmation experience for transgender individuals.

Understanding predictors of improvement in risky drinking in a U.S. multi-site, longitudinal cohort study of transgender individuals: Implications for culturally-tailored prevention and treatment efforts

OBJECTIVE

While transgender people report higher rates of risky drinking than the general population, no studies have examined transgender alcohol use longitudinally. This study investigated minority stress and identity development predictors of improvement in risky drinking among transgender individuals.

METHODS

Data come from a multi-site, longitudinal cohort study of U.S. transgender individuals (N = 330) and include measures of enacted stigma, felt stigma, identity development, and risky alcohol use. Theory-driven, hierarchical multivariable logistic regression was used to investigate the hypothesis that minority stress and identity development factors are related to improvement in risky drinking between baseline and 1-year follow-up.

RESULTS

Baseline risky drinkers (n = 106; 37.1%) were younger and more likely to have female sex assigned at birth. At 1-year follow-up, 68 baseline risky drinkers (64.2%) reported persistent risky drinking, while 38 (35.8%) reported improved drinking. Controlling for demographics and study site, female sex assigned at birth and enacted stigma were associated with lower odds of improved drinking. Non-white/Hispanic race/ethnicity, felt stigma, change in gender role/expression for 1-5 years, and diffuse-avoidant identity style were associated with higher odds of improvement.

CONCLUSIONS/IMPORTANCE

This is the first study to identity predictors of improvement in risky drinking among transgender individuals. Compared to trans-feminine individuals (assigned male at birth), trans-masculine individuals (assigned female at birth) were more likely to report risky drinking at baseline and had lower odds of improvement at 1-year follow-up. Improved drinking may be facilitated by preventing anti-transgender discrimination. Felt stigma and diffuse-avoidant identity style may lower alcohol risk via avoidance of drinking venues. Further research is needed to explicate these relationships and to inform culturally-tailored alcohol interventions for this at-risk population.

Estimating the Prevalence of HIV and Sexual Behaviors Among the US Transgender Population: A Systematic Review and Meta-Analysis, 2006-2017

Background. Transgender women (transwomen) in the United States have been shown to have high HIV risk with Black and Hispanic transwomen being particularly vulnerable. Growing research on transgender men (transmen) also shows increased HIV risk and burden, although not as much is known for this transgender population.Objectives. This systematic review estimates the prevalence of self-reported and laboratory-confirmed HIV infection, reported sexual and injection behaviors, and contextual factors associated with HIV risk of transgender persons living in the United States.Search Methods. We searched the HIV Prevention Research Synthesis database and MEDLINE, EMBASE, PsycINFO, CINAHL, and Sociological Abstracts databases from January 2006 to March 2017 and January 2006 to May 2017, respectively. Additional hand searches were conducted in December 2017 to obtain studies not found in the literature searches.Selection Criteria. Eligible reports were published US-based studies that included transgender persons and reported HIV status.Data collection and analysis. Data were double-coded and quality assessed. We used random-effects models employing the DerSimonian-Laird method to calculate overall prevalence of HIV infection, risk behaviors, and contextual factors for transwomen, transmen, and race/ethnicity subgroups.Main Results. We reviewed 88 studies, the majority of which were cross-sectional surveys. Overall laboratory-confirmed estimated prevalence of HIV infection was 9.2% (95% confidence interval [CI] = 6.0%, 13.7%; κ = 24). Among transwomen and transmen, HIV infection prevalence estimates were 14.1% (95% CI = 8.7%, 22.2%; κ = 13) and 3.2% (95% CI = 1.4%, 7.1%; κ = 8), respectively. Self-reported HIV infection was 16.1% (95% CI = 12.0%, 21.2%; κ = 44), 21.0% (95% CI = 15.9%, 27.2%; κ = 30), and 1.2% (95% CI = 0.4%, 3.1%; κ = 7) for overall, transwomen, and transmen, respectively. HIV infection estimates were highest among Blacks (44.2%; 95% CI = 23.2%, 67.5%; κ = 4). Overall, participation in sex work was 31.0% (95% CI = 23.9%, 39.0%; κ = 39). Transwomen (37.9%; 95% CI = 29.0%, 47.7%; κ = 29) reported higher participation in sex work than transmen (13.1%; 95% CI = 6.6%, 24.3%; κ = 10; P = .001). Most outcomes indicated high heterogeneity in the overall and subgroup analyses.Conclusions. The availability of more data allowed us to calculate estimates separately for transwomen and transmen. HIV prevalence estimates for US transwomen were lower than previous estimates, but estimates for HIV prevalence and participation in sex work were higher when compared with transmen. Evidence gaps remain for transmen and the syndemic relationship of HIV, risky behaviors, and contextual factors specific to the transgender experience.Public Health Implications. This study highlights gender disparities for HIV and risky sexual behavior, as well as evidence gaps that exist for transmen. Tailored programs and services for the transgender population need to be developed to encourage use of and access to HIV prevention services.
