Associations Between Transgender Identity, Sleep, Mental Health and Suicidality Among a North American Cohort of College Students

Is cardiovascular disease risk in transgender, gender-diverse, and non-binary adults associated with autonomic imbalance?

Blood pressure is a key indicator of cardiovascular health with chronically high levels increasing the risk of cardiovascular diseases (CVD) such as heart attack and stroke. Emerging evidence shows that transgender, gender-diverse, and non-binary (TGD) adults tend to have higher blood pressure than age-matched cisgender adults, corresponding to an increased CVD risk in this population. Yet, the mechanisms underlying elevated blood pressure in TGD adults remain unclear, posing challenges to TGD-affirming healthcare. Given the autonomic nervous system's role in CVD - wherein reduced parasympathetic and heightened sympathetic activity are key risk factors for CVD - this review explores the question: "Is cardiovascular disease risk in TGD adults associated with autonomic imbalance?" Limited research exists on autonomic balance within TGD populations. Accordingly, this review considers how TGD-specific factors, such as minority stress, lifestyle behaviors, sex and gender, and hormones (i.e., testosterone, estrogen, progesterone), may impact autonomic balance. Finally, this review aims to underscore the critical need for interdisciplinary research to elucidate these mechanisms and advance TGD-inclusive healthcare in the domains of autonomic control of blood pressure and overall cardiovascular health.

Gender Identity Disparities in Early Adolescent Sleep: Findings from the Adolescent Brain Cognitive Development Study

Purpose: Our aim was to examine associations between transgender identity and sleep disturbance in a demographically diverse, national sample of U.S. early adolescents. Methods: We conducted a cross-sectional analysis of the Adolescent Brain Cognitive Development Study from Year 3 (2019-2021, n = 10,277, 12-13 years) to investigate the association between transgender identity and caregiver-reported measures of their adolescent's sleep, assessed by the Sleep Disturbance Scale for Children. Results: Transgender adolescents had a higher risk of overall sleep disturbance and symptoms of insomnia and excessive sleepiness. Furthermore, per caregiver report, transgender adolescents were more likely to have shorter sleep duration categories; particularly concerning is the significant risk of <5 hours of sleep for transgender adolescents compared with their cisgender peers. Conclusion: These findings indicate that transgender adolescents had worse caregiver-reported sleep outcomes compared to cisgender peers. This study highlights the need for screenings and interventions targeted at improving sleep among transgender adolescents.

Sleep health among sexual and gender minority people in the United States: A scoping review

Sleep has been found to be essential to physical and mental health. Sexual and gender minority (SGM; e.g., lesbian, gay, bisexual, transgender, nonbinary) individuals experience significant health disparities, and emerging research indicates that this includes disparities in sleep health. However, the current literature on sleep health in this population has not previously been rigorously reviewed. This scoping review provides a comprehensive overview and synthesis of the current literature on SGM sleep health in the United States. Following established scoping review methodology, we systematically searched PubMed, CINAHL, PsycINFO, LGBTQ + Source, and Scopus; 76 studies met inclusion criteria. Included studies indicated significant sleep disparities exist for SGM people, particularly sexual minority women and gender minority people. Social determinants of health, including bullying and discrimination, were associated with worse sleep health. Included studies were heterogeneous and had methodological weaknesses, leaving opportunities for future research. Overall, findings point to the need for more rigorous research to advance understanding of sleep health across SGM subgroups and inform interventions to improve sleep health among SGM people, given the known negative impact of poor sleep on overall health.

Assessment of sleepiness role in working memory and whole-body reaction time

BACKGROUND

Sleep provides physical and mental strength, and natural sleep is essential for cell growth, strengthening, stabilizing, and accelerating the improvement of memory function.

OBJECTIVE

The current investigation aimed to explore working memory influenced by sleepiness and related to whole-body reaction time, in order to identify some facets of the dynamics of this memory. To the best of our knowledge, this triple has not yet been explored in the literature.

METHODS

This study cross-sectional, descriptive-analytical was performed on a sample total of 45 volunteer undergraduate academic students were recruited by convenience sampling, including 35 females and 10 males with a mean age of 21.08 ± 1.10 years of old. Data were collected via a demographic checklist, Epworth Sleepiness Scale (ESS) questionnaire, Digital Maze test (for working memory), and visual/auditory whole-body reaction time measurement.

RESULTS

The working memory of each subject was divided into three types:1) thoughtful and precise, 2) Cautious and Conservative, and 3) messy and inaccurate. The triple of working memory, reaction time, and sleep versus sleepiness were all significantly related (P = 0.017-0.05).

CONCLUSION

The authors concluded that there might be some established infrastructure for adult working memory, while there might be a floating operator of working memory as well; influenced by various parameters, this study was influenced by sleep adequacy and physical readiness.

Characterising the activity, lifestyle behaviours and health outcomes of UK university students: an observational cohort study with a focus on gender and ethnicity

BACKGROUND

Health-related outcomes and behaviours in university students are known to be poor relative to the general population. The substantial contextual shifts related to the COVID-19 pandemic, combined with increased numbers of students from minoritised ethnicity backgrounds and presenting as trans and gender diverse (TGD), means that up-to-date information is unavailable. The primary aim of this study was therefore to characterise the current movement, dietary and lifestyle behaviours, mental health, and Body Mass Index (BMI) of UK university students and assess differences between genders and ethnic groups.

METHODS

An online, self-report survey was administered across three years (2021-2023). Three independent cohorts of university students' (n = 6,327) completed the survey on four key topic areas. One-way ANOVAs were used to assess differences between genders (men, women, TGD), and independent samples t-tests were used to assess differences between ethnic groups (White, Minoritised Ethnicity).

RESULTS

30% of students were not meeting physical activity guidelines, 54% were sedentary for ≥ 6 h·d- 1, 83% had poor diet quality, 51% were in high or increased risk groups for alcohol consumption, 18% experienced terrible or poor sleep quality, and 32% were overweight or obese. Gender differences were present for all variables other than walking physical activity (WPA) (P < 0.05), with men having better mental health and engaging in healthier movement and sleeping behaviours, whereas women had more healthful dietary and drinking behaviours, and TGD students had poorer outcomes compared to cis-gender students in most domains. Differences between White and minoritised ethnicity students were present for all variables other than sedentary behaviour, diet quality, WPA and BMI (P < 0.05); students of minoritised ethnicity engaged in better movement, drinking and sleep behaviours in addition to having more positive mental health than White students.

CONCLUSION

The findings of the current study provide an update on the landscape of UK university students' health and health-related behaviours. Overall, health-related outcomes and behaviours are poor in this population and these data suggest that gender and ethnicity play a role in determining students' health and health-related behaviours. Therefore, these factors should be considered when developing strategies to promote healthy living in the context of higher education.

The relationship of race, ethnicity, gender identity, sex assigned at birth, sexual orientation, parental education, financial hardship and comorbid mental disorders with quality of life in college students with anxiety, depression or eating disorders

BACKGROUND

Previous studies showed that comorbidity and demographic factors added to burden on health-related quality of life (HRQoL). Only one study explored the relationship between HRQoL and comorbidity in college students with mental disorders, leaving generalizability of findings uncertain. Less is known about the association of demographics on HRQoL. This study investigated HRQoL based on demographics and comorbidity among college students with mental disorders.

METHODS

Participants were students (N = 5535) across 26 U.S. colleges and universities who met criteria for depression, generalized anxiety, panic, social anxiety, post-traumatic stress, or eating disorders based on self-report measures. ANOVA and linear regressions were conducted.

RESULTS

Overall, female, minoritized (gender, sexual orientation, race, or ethnicity), and lower socioeconomic status students reported lower HRQoL than male, heterosexual, White, non-Hispanic, and higher socioeconomic status peers. After accounting for comorbidity, differences in physical HRQoL based on sex assigned at birth and gender were no longer significant. For mental HRQoL, only gender and sexual orientation remained significant. A greater number of comorbidities was associated with lower HRQoL regardless of demographic group.

LIMITATIONS

The non-experimental design limits causal inference. The study focused on univariable associations without examining potential interactions between demographic factors. Future research should explore structural factors like discrimination.

CONCLUSION

Results suggested that increased comorbidities placed an additional burden on HRQoL and that certain demographic groups were more vulnerable to HRQoL impairment among students with mental disorders. Findings suggest the need for prevention of disorders and their comorbidity and implementing tailored interventions for specific student subgroups with increased vulnerability.

Gender identity and symptoms of anxiety and depression and their relationship with sleep disorders among Polish adolescents during the Covid-19 pandemic and the outbreak of war in the Ukraine

INTRODUCTION

For most people, gender identity is consistent with biological sex and such people are called cisgender. People in whom such a relationship does not occur or occurs to a lesser extent are referred to as gender non-conforming-and these include transgender, non-binary, agender and gender-fluid people. These individuals are usually affected by minority stress, which, combined with the circumstances of the pandemic and Russian aggression against Ukraine, may have led to mental disorders and sleep disorders in this population. The aim of the study was to analyze the symptoms of anxiety, depression and insomnia in a group of Polish youth during the Covid-19 pandemic and the outbreak of the war in Ukraine, taking into consideration gender differences, including non-binary gender.

METHODS

The study involved 1621 secondary school students aged 14 to 19, the average age was 16.73 ± 1.35, including 857 girls, 690 boys and 74 people who defined their gender as non-binary. A set of questionnaires for the Diagnosis of Depression in Children (CDI 2), the State-Trait Anxiety Inventory (STAI), the X-1 subscale, The Athens Insomnia Scale (AIS) and an original questionnaire of sociodemographic data were used in research.

RESULTS

Analyzing the results obtained in the study group, the respondents scored an average of 17.99 ± 9.55 points in the assessment of depressive symptoms. After division into groups taking into account gender, the corresponding score was 19.69 ± 9.40 points for girls, 15.03 ± 8.68 for boys and 25.86 ± 9.91 for non-binary people. The difference was statistically significant (p = 0.000) in all three study groups. In the anxiety symptoms assessment, the respondents scored an average of 46.92 ± 11.67 points. After division into gender groups, the corresponding score was 49.21 ± 11.12 points for girls, 43.39 ± 11.47 for boys and 53.39 ± 10.41 for non-binary people. The difference was statistically significant (p = 0.000) in all three study groups. Analyzing the results obtained in The Athens Insomnia Scale (AIS), the average score was 8.31 ± 4.58 points, which allows to evaluate sleep onset as a norm. After dividing into groups, the results were 8.95 ± 4.55 points, respectively for girls, 7.19 ± 4.21 points for boys and 11.35 ± 5.43 for non-binary people, the difference was significant in terms of comparisons between all statistically tested groups. The analysis of the relationships between the studied variables was presented for each gender separately. Statistically significant positive correlations were found between the results obtained on the scale assessing depressive symptoms (CDI-2) and anxiety symptoms (STAI-X1) and the results obtained on the AIS scale.

CONCLUSIONS

Among the studied group of teenagers, the highest intensity of depressive symptoms is demonstrated by non-binary people, followed by females, and finally by males. Similar results were obtained in the assessment of anxiety symptoms. The non-binary group achieved results indicating sleep disorders, while the cisgender group's results of sleep onset were borderline normal. Whatsmore, the greater the severity of depressive and anxiety disorders, the greater the sleep disorders in all study groups, regardless of gender.

Lifestyle behaviors and mental health outcomes in sexual and gender minority graduate students

OBJECTIVE

There are well-documented health disparities among sexual and/or gender minority (LGBTQ+) individuals generally, but there is limited research investigating the disparities in health-related lifestyle factors and mental health among LGBTQ+ graduate students, which is a group that may be especially vulnerable.

PARTICIPANTS

This project was a secondary analysis of data from the American College Health Association's National College Health Assessment's (NCHA) Fall 2019 wave, which included 7,766 graduate students.

METHODS

Students self-reported engagement in health-related lifestyle factors and psychological distress. Welch's independent samples t-tests were used to compare differences in psychological distress and lifestyle behaviors and multiple linear regression models were used to test lifestyle factors as predictors of LGBTQ+ psychological distress.

RESULTS

LGBTQ+ graduate students reported worse lifestyle profiles compared to their peers and greater psychological distress. Sleep quality had the strongest association with psychological distress among LGBTQ+ graduate students.

CONCLUSIONS

These findings have important implications for policies and interventions to improve health and decrease suffering in LGBTQ+ graduate students.

An exploratory study of stressors, mental health, insomnia, and pain in cisgender girls, cisgender boys, and transgender and gender diverse (TGD) youth

INTRODUCTION

Transgender and gender-diverse (TGD) youth experience more stressors and are therefore at a higher risk of health problems compared with their cisgender peers. The aim of this study was to investigate the prevalence of TGD youth in a general population sample and to explore a wide variety of health-related factors. We investigate differences in stressors and health outcomes between TGD youth and cisgender girls and boys and the influence of stressors and demographic factors on health outcome in the whole group.

METHODS

Cross-sectional survey data from a Swedish school-based study were used (N = 3,067, M = 17.8 years). Those who had reported their gender identity as "other" or other than their assigned gender (N = 41) were compared with cisgendered girls (n = 1,544) and boys (n = 1,482). Regression models in the whole group explored if demographics and stressors statistically predicted health outcomes.

RESULTS

In comparison with cisgender girls and boys, TGD youth (1.3% of the whole sample) reported a higher prevalence of self-harm and pain problems. Both TGD youth and cisgender girls more frequently reported insomnia, social anxiety, depressive symptoms, pain, and stressors compared with cisgender boys. When only demographic variables were entered, but not when stressors were added to the model, being TGD magnified the odds of depressive symptoms, sub-diagnostic social anxiety, and pain problems. Stressors magnified the odds of reporting health problems for the whole group.

CONCLUSION

TGD youth generally reported more stressors, which negatively influence health outcomes. Results are important for professionals who meet TGD youth.

Neurologic Care for Transgender and Gender-Diverse People: A Review of Current Evidence and Clinical Implications

Purpose of Review

To summarize the literature on neurologic care for transgender and gender-diverse (TGD) people and provide implications for clinical practice.

Recent Findings

There are limited data on the frequency and management of neurologic conditions among TGD people. TGD people have a higher prevalence of various neurologic conditions compared with cisgender or general population cohorts, including migraine, subjective cognitive decline, sleep disturbances, functional disorders, and cerebrovascular disease. Gender-affirming hormone therapy interacts with commonly prescribed neurologic medications and increases stroke risk among transfeminine people. Sex hormones and sex chromosomes may play a role in neurodegeneration and disability progression in neuroimmunologic diseases. Clitoral reduction surgeries on intersex children can cause neurologic disability and sexual dysfunction in adulthood. Socioeconomic disparities among TGD people contribute to health care barriers.

Summary

Neurologists should consider the unique experiences and health care needs of TGD people in their clinical practice and research protocols.

Sexual and Gender Minority Sleep Health Disparities and Minority Stress in Early Adolescence

PURPOSE

Sleep is essential to adolescent development. Sexual and gender minority (SGM; e.g., lesbian, gay, bisexual, transgender) adults are at high risk for poor sleep, partially due to minority stress (e.g., discrimination). However, sleep has rarely been studied among SGM adolescents. In a national sample of early adolescents, we analyzed sexual minority (SM) and gender minority (GM) identity, gender incongruence, and gender nonconformity in association with sleep and tested minority and general stressors as mediators.

METHODS

We cross-sectionally analyzed data from 10,070 adolescents aged 10-14 in the Adolescent Brain Cognitive Development℠ Study. Using logistic regression models, we analyzed associations between identity (SM and GM), sexual identity discrimination, minority and general stressors (sexual identity discrimination, teasing, and conflict with parents) and sleep health (duration, latency, and disturbance). We used Baron and Kenny's method to test for mediation.

RESULTS

Participants reported sexual identity (4% SM, 4% questioning) and gender identity (0.4% GM, 0.6% questioning); 65% were White, 20% were Hispanic, and 52% were assigned male at birth. Compared to heterosexual, SM participants had higher odds of short sleep duration, long sleep latency, and sleep disturbance. GM participants and those reporting gender incongruence and nonconformity had higher odds of long sleep latency and sleep disturbance. Sexual identity discrimination and general social stressors partially mediated some associations.

DISCUSSION

SGM participants reported poorer sleep. Minority and general social stressors partially accounted for some disparities. Policies need to address SGM identity-based discrimination and challenge social norms that produce minority stress for SGM early adolescents.

Efficacy and underlying mechanisms of three-circle post standing qigong on insomnia in college students: a four-arm, double-blind, randomized controlled trial protocol

BACKGROUND

Insomnia is common in college students, but its impact on health and wellbeing is often neglected. Enhancing sleep quality through targeted interventions could improve overall health and reduce the risk of consequent co-morbidities and mental health problems. Qigong exercises have been shown to significantly improve sleep quality and relieve insomnia. Three-circle Post Standing (TCPS) can help integrate body, breath, and mind, a fundamental principle of Qigong that promotes holistic wellbeing. In this clinical trial, we aim to (1) evaluate the feasibility, safety, and therapeutic efficacy of administering TCPS to improve sleep quality and quality of life in college students with insomnia; (2) explore the neurophysiological mechanisms underlying the mind adjustments mediated by TCPS in insomnia; (3) investigate body and breath pathophysiology mediated by TCPS in insomnia; and (4) assess the long-term efficacy of TCPS in terms of sleep quality and quality of life.

METHODS

This will be a prospective, parallel, four-arm, double-blind randomized controlled trial to investigate the effects and underlying mechanisms of TCPS on college students with insomnia. One hundred college students meeting diagnostic criteria for insomnia will be randomly assigned to receive either 14 weeks of standardized TCPS training (two weeks of centralized training followed by 12 weeks of supervised training) or sham-control Post Standing training. Efficacy outcomes including sleep quality, quality of life, neurophysiological assessments, plantar pressure, biomechanical balance, and physical measures will be collected at baseline, eight weeks (mid-point of supervised training), and 14 weeks (end of supervised training). Sleep quality and quality of life will also be evaluated during the four- and eight-week follow-up.

DISCUSSION

This trial will be an important milestone in the development of new therapeutic approaches for insomnia and should be easily implementable by college students with insomnia. The neuro- and pathophysiological assessments will provide new insights into the mechanisms underlying TCPS.

CLINICAL TRIAL REGISTRATION

This trial has been registered in the China Clinical Trials Registry (registration number: ChiCTR2400080763).

A Pilot Study of Symptoms of Major Depressive Disorder in Medical Students at an Osteopathic Medical School Before and After High-Stakes Examinations

Background

Given the high prevalence of symptoms of major depressive disorder (MDD) in medical students, identifying factors that impact the development of such symptoms is important. Previous data suggest that medical students can experience symptoms of MDD after medical school exams. It is not known if medical students experience more symptoms of MDD directly before or after exams. The aim of the current study is to determine the prevalence of symptoms of MDD in first- and second-year medical students directly before and after high-stakes medical school examinations.

Methods

Two anonymous surveys were sent via REDCap to first- and second-year medical students at the University of New England College of Osteopathic Medicine. A pre-exam survey on the day of the exam asking about the past three days' MDD symptoms, and a post-exam survey sent three days after the exam asking about MDD symptoms experienced after the exam was sent out to a total of 391 students with a response rate of 23%.

Results

First- and second-year medical students regardless of gender experienced symptoms of MDD at higher rates before exams than afterwards. Female students experienced symptoms of MDD (as defined by the DSM-5) including sadness, sleep disturbances, and feelings of guilt or worthlessness at a greater rate compared to males before exams. After exams, females were more likely to experience sleep disturbances and decreased energy. Second-year male students were the least likely to experience symptoms of MDD.

Conclusion

First- and second-year medical students can experience symptoms of MDD surrounding exams. This study highlights the emotional burden that students may carry near exams. It underscores the importance of further research on this topic to evaluate the effect exams have on the mental health of medical students during their training.

The motivation behind better sleep: self-determination as a framework for examining sleep outcomes in college students

OBJECTIVE

To examine sleep health within a self-determination framework across a diverse college sample.

PARTICIPANTS

A nonclinical sample of undergraduate students (n = 399) from a large, urban, public university in the Mid-Atlantic United States in Spring 2020.

METHODS

Participants were recruited via an online research participation portal and received extra credit for participation. All measures were administered via an online survey.

RESULTS

Basic psychological need satisfaction was associated with sleep health. This association was partially mediated by sleep hygiene but not by regulatory style. There were no racial/ethnic differences in sleep health, sleep hygiene, basic need satisfaction, or regulatory style. Men reported more maladaptive motivational styles for sleep health, and non-binary/transgender students reported worse sleep hygiene.

CONCLUSION

Basic psychological need satisfaction and sleep hygiene are critical targets for intervention across diverse college student populations. Motivation may be less critical for nonclinical interventions.

Images: Irregular sleep-wake rhythm disorder in transgender individuals

Growing evidence suggests that transgender individuals face a significant health disparity and are particularly vulnerable to sleep disorders. We present two patients who developed irregular sleep-wake rhythm disorder after gender reassignment and hormone replacement therapy. The growing interest in transgender health warrants further evaluation of the effects and frequency of all sleep disorders in this population. Efforts to address sleep disorders should consider assessing sleep disturbance in terms of sleep/wake patterns and schedules.

Mental Health Disparities in Sexual Minority and Transgender Women: Implications and Considerations for Treatment

Minority stress theory offers an explanation of how discrimination, marginalization, harassment, and violence against sexual minority and transgender women are connected to mental health disparities. Particularly, these groups are vulnerable to body image issues, disordered eating, higher rates of mood and anxiety disorders, suicide and nonsuicidal self-injury, and substance use. Discrimination is also experienced within clinical settings, which may lead this population to postpone or avoid treatment. Clinicians play a crucial role in reducing barriers to health care by developing cultural competency and ensuring safe and affirming spaces within their practice.

Caring for Sexual and Gender Minority Adults with Cardiovascular Disease

This article summarizes existing evidence on cardiovascular disease (CVD) risk and CVD diagnoses among sexual and gender minority adults and provides recommendations for providing nursing care to sexual and gender minority adults with CVD. More research is needed to develop evidence-based strategies to care for sexual and gender minority adults with CVD.

Insomnia among community members in Florida: Associations with demographics, health conditions, and social support

Objectives

To identify associations between demographics, social determinants of health, health conditions, and reported history of insomnia. A cross-sectional study including 11,960 adult community members recruited through HealthStreet, a community outreach program at University of Florida.

Methods

Health assessments were conducted via interviews. Participants reported their demographic background, level of social support, history of health conditions, and insomnia. Logistic regression was used to understand associations between risk factors and history of insomnia.

Results

The prevalence of self-reported insomnia was 27.3%. Adults aged ≥ 65 years (OR = 1.16) and women (OR = 1.18) reported higher rates of insomnia than their counterparts. Black/African American individuals reported lower rates of insomnia (OR = 0.72) than White individuals. Individuals with food insecurity (OR = 1.53), a military history (OR = 1.30), lower social support (OR = 1.24), living alone (OR = 1.14), anxiety (OR = 2.33), cardiometabolic disease (OR = 1.58), and attention-deficit hyperactivity disorder (ADHD) (OR = 1.44) were significantly more likely to endorse insomnia compared with their counterparts. Depression (OR = 2.57) had the strongest association with insomnia.

Conclusions

This study provides evidence regarding who is at greater risk for insomnia among a large community-based sample. Our findings highlight the importance of screening for insomnia, particularly among patients who experience food insecurity, are military veterans, have anxiety, depression, ADHD, or cardiometabolic disease, as well as those who live alone or have lower levels of social support. Future public health campaigns should provide education on insomnia symptoms, treatments, and evidenced-based sleep-promotion strategies.

Social Support and Mental Health Among Transgender and Nonbinary Youth in Quebec

Purpose: Transgender and nonbinary (TNB) youth face elevated levels of discrimination, stigma, mental health disorders, and suicidality when compared with their cisgender counterparts. Family and school support may mitigate some of the effects of the stressors facing TNB youth. This study aimed to better understand the impact of each of these sources of support on TNB youths' mental health and wellbeing. Methods: We used data collected between 2018 and 2019 as part of the Canadian Trans Youth Health Survey, a bilingual online survey to measure social support, physical health, and mental health in a sample of 220 TNB youth aged 14-25 living in Québec, Canada. We examined the relationships among different sources of support, and mental health and wellbeing outcomes using logistic regression. Analyses were conducted on the full sample and according to linguistic groups (French and English). Results: Participants reported high levels of mental health symptoms, self-harm, and suicidality, and mental health symptoms were higher in the English-speaking group (p = 0.005). In models controlling for age, family connectedness was associated with good/excellent self-reported mental health (odds ratio [OR] = 2.62, p = 0.001) and lower odds of having considered suicide (OR = 0.49, p = 0.003) or attempted suicide (OR = 0.43, p = 0.002), whereas school connectedness was associated with higher odds of good/very good/excellent general (OR = 2.42, p = 0.013) and good/excellent mental (OR = 2.45, p = 0.045) health. Conclusion: Family and school support present consistent associations with TNB youths' health and may constitute key areas for intervention for those supporting them.

Discrimination keeps transgender people awake at night: A nationwide cross-sectional survey of 583 transgender adults in South Korea

OBJECTIVES

We sought to investigate the association between transgender identity discrimination and sleep problems among transgender people in South Korea (hereafter, Korea), and whether family support for transgender identity plays a protective role in the association.

DESIGN & SETTING

We analyzed a nationwide cross-sectional survey of 583 Korean transgender adults which was anonymously conducted through an online platform.

MEASUREMENTS

Transgender identity discrimination was assessed using a single-item question. Sleep problems were defined as having any of the following problems: poor sleep quality, short sleep duration, and use of alcohol or sleep medications to fall asleep. Family support for transgender identity was classified into 3 groups as follows: not supportive, supportive, and unaware of participants' transgender identity.

RESULTS

Of 583 participants, 383 (65.7%) experienced transgender identity discrimination over the past 12 months. Participants who experienced transgender identity discrimination were 1.48 times (95% confidence intervals [95% CI] = 1.19-1.83) more likely to have any sleep problems, compared to those who never experienced transgender identity discrimination. When stratified by family support level, the associations between transgender identity discrimination and sleep problems remained statistically significant only among those with a family unsupportive (adjusted prevalence ratio [aPR] = 1.64; 95% CI = 1.16-2.31) or unaware (aPR = 1.60; 95% CI = 1.01-2.52) of participants' transgender identity. However, the association was not statistically significant among those with a supportive family (aPR = 1.41; 95% CI = 0.96-2.07).

CONCLUSION

Given transphobic environments in Korea, legal and institutional efforts are required to reduce transgender identity discrimination (eg, anti-discrimination laws) as well as to build trans-specific family resources.

Nonconforming gender expression and insufficient sleep among adolescents during COVID-19 school closure and after school reopening

BACKGROUND

Gender nonconformity (GNC) (i.e., gender expression that differs from gender role expectations for feminine or masculine appearance and behavior) is an under-researched area of adolescent sleep health. The COVID-19 lockdown offers an opportunity to understand how the effect of GNC on adolescent health outcomes changes between school closure and reopening.

METHODS

We conducted a cross-sectional study in Shanghai, China, in 2020. The sample size for analysis was 3,265. The age-specific insufficient sleep was estimated according to National Sleep Foundation's sleep duration recommendations. The self-perceived and self-rated GNC were measured by the two items "On the same scale that goes from 100% as a girl to 100% as a boy, where do you think others see you?" and "On a scale that goes from feeling 100% like a girl to feeling 100% like a boy, where do you see yourself?", and birth sex. In addition, we calculated sex-stratified adjusted odds ratios (AORs) of insufficient sleep for students with high and moderate GNC compared to students with low GNC. Finally, we measured the AORs with self-perceived and self-rated GNC during COVID-19 school closure and reopening.

RESULTS

Among 3,265 students in grade 6-12 in the analytic sample, 1,567(48.0%) were assigned female at birth (AFAB), 3,188 (97.6%) Han, and 1,921(58.8%) in grade 6-9. Among AFAB students, high self-perceived GNC was significantly associated with insufficient sleep (AOR,1.65; 95%CI,1.30-2.09) during school closure. Insufficient sleep was associated with high self-rated GNC (AOR,1.73; 95%CI,1.23-2.44) and moderate self-rated GNC (AOR,1.69; 95%CI,1.29-2.22) during school closure. After school reopening, neither self-perceived nor self-rated GNC was associated with insufficient sleep among AFAB students. Among assigned male at birth (AMAB) students, none of the two kinds of GNC was associated with insufficient sleep in the two periods during the COVID-19 pandemic.

CONCLUSIONS

This study suggests GNC is only associated with insufficient sleep among AFAB students during school closure. Furthermore, the association is nonsignificant among AMAB students. These findings indicate that GNC-related stigma within the family could be a risk factor for insufficient sleep among AFAB adolescents.

Sleep disturbance and suicide risk among sexual and gender minority people

Sleep disturbance has emerged as an independent, mechanistic, and modifiable risk factor for suicide. Sexual and gender minority (SGM) people disproportionately experience sleep disturbance and are at higher risk of death by suicide relative to cisgender and/or heterosexual individuals. The present narrative review evaluates nascent research related to sleep disturbance and suicide-related thoughts and behaviors (STBs) among SGM populations, and discusses how experiences of minority stress may explain heightened risk among SGM people. Although there is a growing understanding of the link between sleep disturbance and STBs, most research has not been conducted in SGM populations or has not examined suicide as an outcome. Research is needed to examine whether and how aspects of sleep disturbances relate to STBs among SGM people in order to better tailor sleep treatments for SGM populations.

Gender identity and transition: relationships with sleep disorders in US youth

STUDY OBJECTIVES

Transgender or gender-nonconforming (TGNC) identity is associated with higher burden of sleep disorders relative to cisgender identity. However, the role of gender-affirming therapy (GAT) in sleep disorders is poorly understood. This study examined relationships between TGNC identity, transition, and sleep disorders among TGNC and cisgender youth.

METHODS

This retrospective cross-sectional study utilized a large US-based administrative claims database (deidentified Optum Clinformatics Data Mart Database) to identify youth aged 12-25 years who obtained a diagnosis of TGNC identity and those who pursued GAT. Descriptive statistics estimated distributions of demographic and health characteristics by gender identity. Unadjusted and age-adjusted logistic regression models were used to examine associations between TGNC identity, GAT, and sleep disorders.

RESULTS

This study included 1,216,044 youth, of which 2,603 (0.2%) were identified as TGNC. Among the 1,387 TGNC who pursued GAT, 868 and 519 were identified as transmasculine and transfeminine, respectively. Adjusted analysis showed increased odds of insomnia (odds ratio = 5.4, 95% confidence interval 4.7, 6.2), sleep apnea (odds ratio = 3.0, 95% confidence interval 2.3, 4.0), and other sleep disorders (odds ratio = 3.1, 95% confidence interval 2.5, 3.9) in TGNC relative to cisgender youth. Decreased odds of any sleep disorder were observed in the TGNC youth on GAT (odds ratio = 0.5, 95% confidence interval 0.4, 0.7) relative to those not on GAT.

CONCLUSIONS

This study demonstrated a high burden of sleep disorders in TGNC youth in comparison to cisgender. However, GAT may confer a protective effect on sleep disorders among TGNC youth. Longitudinal assessments of sleep disorders prior to and post-GAT are needed to uncover their temporal relationships.

Examining the associations of gender minority stressors with sleep health in gender minority individuals

OBJECTIVES

Investigate the associations of gender minority stressors (including stigma consciousness [SC] and gender-related discrimination [GRD]) with sleep health in gender minority individuals.

DESIGN

Cohort.

PARTICIPANTS

279 gender minority individuals.

MEASUREMENTS

SC and GRD were measured using the Stigma Consciousness and Everyday Discrimination scales, respectively. Sleep disturbance was assessed using the PROMIS Sleep Disturbance measure. Subjective short sleep duration (<7 hours) was assessed. We used k-means longitudinal clustering to identify minority stress clusters (including SC and GRD scores). Linear and logistic regression models were used to examine the associations of these clusters with sleep disturbance and sleep duration, respectively, adjusted for demographic characteristics.

RESULTS

Mean age was 36.9 ± 13.6 years; most were non-White (54.5%), 52.5% were transmasculine, and 22.6% were heterosexual. Mean sleep disturbance score was 17.2 ± 6.1 (range 6-30) and 52% reported short sleep duration. We identified 3 minority stress clusters. Compared to participants with low SC/low GRD, those with high SC/low GRD (B 3.33, 95% confidence interval [CI] = 1.64, 5.01) and high SC/high GRD (B 4.51, 95% CI = 2.63, 6.39) had worse sleep disturbance scores. Participants in the high SC/high GRD cluster were more likely to report short sleep duration relative to the low SC/low GRD cluster (adjusted odds ratios 2.17; 95% CI = 1.11-4.26).

CONCLUSIONS

Participants with both high SC and high GRD had worse sleep health. Future longitudinal studies should examine factors that drive the link between gender minority stress and sleep health in gender minority individuals to inform sleep health interventions tailored for this population.

Abnormal hippocampal substructure volume in insomnia disorder

To date, our understanding of the role of abnormal hippocampal volume in imaging studies of insomnia disorders (ID) has remained in apparent contradiction. Given that hippocampal function can be mapped to anatomically defined substructures, the hippocampal substructure volume can be examined in detail at present. In this study, we examined the volumes of hippocampal substructures between IDs and healthy controls (HC) to accurately find hippocampal markers of ID. First, we used the automated hippocampal substructure module in FreeSurfer6.0 to inspect T1-weighted magnetic resonance images between 22 IDs and 30 HC. Then, 12 hippocampal substructures were computed. Volumetric assessment was performed at the hippocampal substructure level between groups. Our study revealed significant reduced volume of the bilateral fimbria in IDs compared with HC (p < 0.05/12, Bonferroni corrected), although there was no difference in the total volume of hippocampus. In addition, the correlation analysis showed that the total hippocampal volume of the left hemisphere was negatively correlated with Pittsburgh Sleep Quality Index (PSQI) scores. With regard to hippocampal substructure results, negative correlations were detected between bilateral fimbria volume and clinical variables (i.e., PSQI, SDS, and SAS) in all subjects. Taken together, we revealed marked differences in the volume of the hippocampal substructure between IDs and HC, which provided a more accurate structural imaging marker for the pathological of ID.
