Getting Precise about Gender and Sex Measurement: A Primer for Epidemiologists.

Accurately measuring gender and sex is crucial in public health and epidemiology. Iteratively reexamining how variables-including gender and sex-are conceptualized and operationalized is necessary to achieve impactful research. Reexamining gender and sex advances epidemiology toward its goals of health promotion and disease elimination. While we cannot reduce the complexities of sex and gender to simply an issue of measurement, striving to capture these concepts and experiences accurately must be an ongoing dialogue and practice-to the benefit of the field and population health. We assert that epidemiology must counteract misconceptions and accurately measure gender and sex in epidemiology. We aim to summarize existing critiques and guiding principles in measuring gender and sex that can be applied in practice.

Health and Health Care Among Transgender Adults in the United States.

Transgender (trans) communities in the USA and globally have long organized for health and social equity but have only recently gained increased visibility within public health. In this review, we synthesize evidence demonstrating that trans adults in the USA are affected by disparities in physical and mental health and in access to health care, relative to cisgender (nontrans) persons. We draw on theory and data to situate these disparities in their social contexts, explicating the roles of gender affirmation, multilevel and intersectional stigmas, and public policies in reproducing or ameliorating trans health disparities. Until recently, trans health disparities were largely made invisible by exclusionary data collection practices. We highlight the importance of, and methodological considerations for, collecting inclusive sex and gender data. Moving forward, we recommend routine collection of gender identity data, an emphasis on intervention research to achieve trans health equity, public policy advocacy, and investment in supporting gender-diverse public health leadership.

Solidarity, support and competition among communities of female and male sex workers in Mombasa, Kenya.

Female and male sex workers are at elevated risk for HIV infection, psychological distress and other adverse health outcomes. It is therefore important to understand how sex workers' social relationships with one another might inform psychosocial support services for this population. We conducted semi-structured interviews to examine the formation and nature of social networks of 25 female and 25 male sex workers recruited from bars and clubs in Mombasa, Kenya. Relationships between and among female and male participants were often formed based on a mutual understanding of the challenging nature of sex work. Both groups described their relationships in terms of friendship and brotherhood/sisterhood and highlighted the following benefits of sex worker social networks: economic benefits, access to information about HIV/STIs and protection, and support against violence from clients and law enforcement agents. Social networks were often threatened by competition for clients and hence could result in conflict. However, sex workers explained that their sense of solidarity and reliance on one another for health, protection and economic well-being helped minimise conflict. The social networks of sex workers could therefore be used to leverage or optimise access to HIV prevention and care.

Correlates of Geosocial Networking Applications (GSN Apps) Usage among Gay, Bisexual, and Other Men Who Have Sex with Men in Nigeria, Africa.

Geosocial networking applications (GSN apps) are widely utilized by gay, bisexual, and other men who have sex with men (GBMSM) to meet potential sexual/romantic partners, foster friendships, and build community. However, GSN apps usage has been linked to elevated levels of HIV sexual risk behavior among GBMSM. Little is known about how GSN apps can facilitate HIV sexual risk behaviors, especially among GBMSM in Africa. To fill this gap in research, the present study aimed to characterize the frequency of GSN apps usage and its association with sociodemographic characteristics, sexual health, healthcare access, psychosocial problems, and substance use in a large multicity sample of community-recruited GBMSM in Nigeria (N = 406). Bivariate and multivariable ordinal logistic regression procedures were used to examine factors associated with GSN apps usage. We found that 52.6% of participants reported recent (≤ 3 months) GSN apps use to meet sexual partners. Factors associated with increased odds of GSN apps usage included: being single, having a university degree or higher, reporting higher recent receptive anal sexual acts, being aware of PrEP, having a primary care provider, and reporting higher levels of identity concealment. HIV-related intervention delivered through GSN apps may help curb the spread of HIV among Nigerian GBMSM.

"I Couldn't Afford to Resist": Condom Negotiations Between Male Sex Workers and Male Clients in Mombasa, Kenya.

Male sex workers in Kenya face a disproportionate burden of HIV and often engage in condomless sex with their commercial partners, yet little is known about how condom negotiations between male sex workers and clients take place. We conducted semi-structured interviews with 25 male sex workers and 11 male clients of male sex workers in Mombasa, Kenya, to examine barriers and facilitators to condom use and how condom use negotiation takes place in these interactions. Participants reported positive attitudes toward condom use and perceived condom use to be a health-promoting behavior. Barriers to condom use included extra-payment for condomless sex, low perceived HIV/STI risk with some sexual partners, perceived reduced pleasure associated with using condoms, alcohol use, and violence against male sex workers by clients. Future interventions should address individual- and structural-level barriers to condom use to promote effective condom use negotiation between male sex workers and male clients.

Acceptability of Antiretroviral Pre-exposure Prophylaxis from a Cohort of Sexually Experienced Young Transgender Women in Two U.S. Cities.

Emtricitabine/tenofovir disoproxil fumarate as pre-exposure prophylaxis (PrEP) can prevent HIV infection among at-risk individuals, including young transgender women (YTW). We used baseline data from 230 HIV-uninfected YTW (ages 16-29 years) who were enrolled in Project LifeSkills during 2012-2015. We examined factors associated with perceived acceptability of PrEP use (mean score = 23.4, range 10.0-30.0). Participants were largely transgender women of color (67%) and had a mean age of 23 years (SD = 3.5). In an adjusted multiple linear regression model, PrEP interest (ß = 3.7, 95% CI 2.2-5.2) and having a medical provider who meets their health needs (ß = 2.9, 95% CI 1.3-4.4) was associated with higher PrEP acceptability scores, whereas younger age (21-25 vs 26-29 years) (ß = -2.0, 95% CI - 3.6 to - 0.4) and reporting transactional sex in the past 4 months (ß = - 1.5, 95% CI - 3.0 to - 0.1) was associated with lower PrEP acceptability scores (all p values < 0.05). Enhancing PrEP-related interventions by addressing the unique barriers to uptake among YTW of younger age or those with history of transactional sex could bolster PrEP acceptability for this population.

First They Came for Us All: Responding to Anti-Transgender Structural Violence With Collective, Community-Engaged, and Intersectional Health Equity Research and Advocacy.

This article is a call for collective action across health equity researchers and advocates to build a more just world. We attempt to make sense of senseless structural and interpersonal brutality in the context of the current political climate across the United States, whereby the spectrum of gender nonconformity has been and continues to be stigmatized. From drag performance to transgender identities to gender-affirming health care, extremists have instrumentalized primary levers of democracy-the courts, legislatures, and social media-to attempt to outlaw and eradicate gender expansiveness and those who provide forms of support and care, including gender-affirming medical care, to transgender, nonbinary, and gender-expansive (TNBGE) individuals.

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.

Health equity necessitates the inclusion of gender identity data in COVID-19 clinical trials.

COVID-19 has highlighted the importance of studying differences by sex and gender. The under-reporting of gender identity in COVID-19 studies limits the generalizability of study results to nonbinary persons. Some of the data on sex-assigned associated complications of both COVID-19 infection and COVID-19 immunizations is presented in this manuscript.

Transgender-specific COVID-19-related stressors and their association with depressive symptoms among transgender adults: A nationwide cross-sectional survey in South Korea.

Introduction: COVID-19 has disproportionately impacted marginalized groups, including transgender populations, reproducing and exacerbating inequalities and vulnerabilities that existed in those groups prior to the pandemic. This study aimed to assess the prevalence of transgender-specific COVID-19-related stressors and their association with depressive symptoms among South Korean transgender adults. Methods: We conducted a nationwide cross-sectional study of 564 South Korean transgender adults (trans women, trans men, and nonbinary people) from October 7 to October 31, 2020. We measured four transgender-specific COVID-19-related stressors as follows: (A) had difficulty receiving gender-affirming healthcare due to economic hardship related to COVID-19, (B) had difficulty receiving gender-affirming healthcare due to limited access to hospitals under the COVID-19 situation, (C) had difficulty purchasing a public face mask due to gender information on an identification card, and (D) avoided getting a COVID-19 test in fear of unfair treatment and dirty looks due to gender identity, despite having COVID-19 symptoms. Past-week depressive symptoms were assessed using the Center for Epidemiologic Studies-Depression Scale. Results: Of the total participants, 30.7% experienced any of the four transgender-specific COVID-19-related stressors, and 70.2% were classified as having depressive symptoms during the past week. We found statistically significant associations with depressive symptoms among participants who reported that they had difficulty receiving gender-affirming healthcare due to either economic hardship (adjusted prevalence ratio [aPR] = 1.20, 95% Confidence Interval [CI] = 1.05-1.37) or limited access to hospitals (aPR = 1.15, 95% CI = 1.00-1.32), respectively. Furthermore, those who had two or more of the four transgender-specific COVID-19-related stressors were 1.21 times (95% CI = 1.05-1.40) more likely to report depressive symptoms, compared to those who did not report any stressor. Conclusion: Transgender-specific COVID-19-related stressors may negatively influence depressive symptoms among South Korean transgender adults. Given these findings, transgender-inclusive interventions should be implemented at the policy level during the COVID-19 pandemic in South Korea.

Gender Identity Change Efforts Are Associated with Depression, Panic Disorder, and Suicide Attempts in South Korean Transgender Adults.

Purpose: Gender identity change efforts (GICEs), sometimes referred to as "conversion therapy," are considered pseudoscientific and unethical practices that are not supported by the existing scientific literature. However, a substantial portion of transgender people face such practices during their lives. We assessed lifetime exposure to GICEs and its associations with mental health indicators among transgender adults in South Korea. Methods: We analyzed a nationwide cross-sectional survey of 566 Korean transgender adults conducted in October 2020. Lifetime exposure to GICEs was classified as follows: "never had GICE-related experiences," "received a referral, but did not undergo GICEs," and "undergone GICEs." We assessed mental health indicators, including past-week depressive symptoms; medical diagnosis or treatment of depression and panic disorder; and past 12-month suicidal ideation, suicide attempts, and self-harm. Results: Of the total participants, 12.2% had "received a referral, but did not undergo GICEs," and 11.5% had "undergone GICEs." Compared with those who had "never had GICE-related experiences," participants who had "undergone GICEs" showed significantly higher prevalence of depression (adjusted prevalence ratio [aPR]=1.34, 95% confidence interval [CI]=1.11-1.61), panic disorder (aPR=2.52, 95% CI=1.75-3.64), and suicide attempts (aPR=1.73, 95% CI=1.10-2.72). However, we did not find significant associations between having "received a referral, but did not undergo GICEs" and mental health indicators. Conclusion: Given our findings suggest that lifetime exposure to GICEs may harm transgender adults' mental health, legal restrictions should be imposed to ban GICEs in South Korea.

Adolescent Providers' Experiences of Harassment Related to Delivering Gender-Affirming Care.

PURPOSE: The politicization of adolescent gender-affirming care has occurred alongside targeted harassment (e.g., threats of violence, doxing, bomb threats) of adolescent gender-affirming care providers across the United States. This study sought to explore their experiences of targeted harassment. METHODS: From October to December 2022, mental and physical health gender-affirming care providers from across the United States completed a survey including open-ended questions about the kinds of harassment they experienced (i.e., method and messages of harassment) and its impact on their lives and practices. Thematic analyses were used to analyze their responses. RESULTS: In total, 117 providers completed the survey and 70% shared that either they, their practice, or their institution had received threats specific to delivering gender-affirming care. The most common experiences were threats via social media or mailed letters. Several received death threats. Providers described how targeted harassment impacted their psychological well-being and required them to reassess clinic safety. Additionally, providers expressed the need for a more accurate representation of gender-affirming care in media and stronger advocacy from institutions and organizations emphasizing the importance of this care. DISCUSSION: Adolescent gender-affirming care providers are experiencing targeted harassment, significantly affecting their ability to deliver care to transgender and gender-diverse adolescents and their families. Providers stressed the importance of receiving support from their institutions to ensure their safety. The ongoing sociopolitical climate related to gender-affirming care coupled with targeted harassment of those providing it will further limit access to this care.

Characterizing Problematic Drug Use Among Transgender Women and Cisgender Men During the Emerging HIV Crisis in the Philippines: Implications for Policy Research.

Drug use and HIV are key issues for public health interventions in the Philippines. We examined associations of problematic drug use among 320 Filipinx transgender women (trans-WSM) and cisgender men who have sex with men (cis-MSM). The prevalence of exhibited problematic drug use in this sample was 29.38%. Greater odds of problematic drug use were observed among Filipinx participants who recently engaged in sex work (adjusted OR [aOR] = 2.79, 95% CI [1.08, 7.18]), reported having HIV positive and unknown status vs. negative status (aOR = 3.61, 95% CI [1.39, 9.39], and aOR = 13.99, 95% CI [2.04, 29.69], respectively), exhibited low HIV knowledge (aOR = 4.15, 95% CI [1.82, 9.44]), and displayed hazardous drinking (aOR = 2.77, 95% CI [1.21, 6.33]). Given its correlates of HIV-related indicators, integration of HIV and harm reduction services as a public health intervention could potentially decrease problematic drug use.

Asian, Latinx, or Multiracial? Assessing Filipinxs' Health Conditions and Outcomes by Aggregate Ethnic Category.

INTRODUCTION: Filipinxs are the second-largest Asian subgroup in the USA. While Filipinxs are most often considered Asian when constructing aggregate ethnic categories, recent research has identified a trend of a small portion of Filipinxs identifying as Latinx or multiracial. However, little research had addressed how identification with different aggregate ethnic categories may have implications for identifying health disparities among Filipinxs and how these compare to non-Hispanic whites. METHODS: Bivariate and multivariable regression analyses using 2011-2018 California Health Interview Survey data, comparing Asian Filipinxs, Latinx Filipinxs, and multiracial Filipinxs. RESULTS: In bivariate analyses, Asian Filipinxs had a higher prevalence of diabetes than Latinx or multiracial Filipinxs. After controlling for sociodemographics, Latinx Filipinxs had significantly lower odds of having diabetes or heart disease than Asian Filipinxs. Compared to non-Latinx Whites, Asian Filipinxs reported higher odds of being in fair/poor health, obese or overweight, high blood pressure, and diabetes, multiracial Filipinxs reported higher odds of being obese or overweight, and Latinx Filipinxs reported lower odds of heart disease. DISCUSSION: These findings suggest emerging differences in health linked to identification with different ethnic categories, underscoring the need to investigate nuances among Filipinxs in future research as well as highlighting the utility of emerging sociological insights in health research.

Violence and Victimization in Interactions Between Male Sex Workers and Male Clients in Mombasa, Kenya.

Male sex workers (MSWs) and male clients (MCMs) who engage their services face increased vulnerability to violence in Kenya, where same-sex practices and sex work are criminalized. However, little is known about how violence might arise in negotiations between MSWs and MCMs. This study explored the types of victimization experienced by MSWs and MCMs, the contexts in which these experiences occurred, and the responses to violence among these groups. We conducted in-depth interviews with 25 MSWs and 11 MCMs recruited at bars and clubs identified by peer sex worker educators as "hotspots" for sex work in Mombasa, Kenya. Violence against MSWs frequently included physical or sexual assault and theft, whereas MCMs' experiences of victimization usually involved theft, extortion, or other forms of economic violence. Explicitly negotiating the price for the sexual exchange before having sex helped avoid conflict and violence. For many participants, guesthouses that were tolerant of same-sex encounters were perceived as safer places for engaging in sex work. MSWs and MCMs rarely reported incidents of violence to the police due to fear of discrimination and arrests by law enforcement agents. Some MSWs fought back against violence enacted by clients or tapped into peer networks to obtain information about potentially violent clients as a strategy for averting conflicts and violence. Our study contributes to the limited literature examining the perspectives of MSWs and MCMs with respect to violence and victimization, showing that both groups are vulnerable to violence and in need of interventions to mitigate violence and protect their health. Future interventions should consider including existing peer networks of MSWs in efforts to prevent violence in the context of sex work. Moreover, decriminalizing same-sex practices and sex work in Kenya may inhibit violence against MSWs and MCMs and provide individuals with safer spaces for engaging in sex work.

Evaluating Translation of HIV-Related Legal Protections Into Practice: A Qualitative Assessment Among HIV-Positive Gay, Bisexual, and Other Men Who Have Sex With Men in Manila, Philippines.

Legal protections for people living with HIV (PLHIV) are important for protecting human rights, yet little research has examined how laws translate into awareness and understanding for key populations. The Philippines has recently revised their legal protections for PLHIV in response to its growing HIV epidemic, where HIV-positive gay, bisexual and other men who have sex with men bear the majority of cases. We present findings from interviews with 21 HIV-positive gay, bisexual and other men who have sex with men in Manila, Philippines regarding awareness, understanding, and needs regarding HIV-specific legal protections at the time just before new revisions to the omnibus HIV law were passed. Overall, there was no standardized way participants became aware of legal protections; few became aware through healthcare providers, while most learned through online resources, social media, and advocacy organizations. However, even after learning about HIV-specific legal protections, many found the law too complex to understand or did not understand how to use such protections. This led participants to preemptively take action to avoid HIV-related discrimination, even if they were protected by law. Participants demonstrated a strong desire for interventions and policies to improve legal awareness and understanding for PLHIV, government officials, and private businesses. This research demonstrates the value of increasing awareness and understanding in policy-specific interventions designed to improve quality of life for PLHIV. Interventions centered around legal protections are currently underdeveloped, providing a strong opportunity to integrate such interventions in existing practice or as stand-alone tools to decrease perceived stigmatization.

Opioid pain medication misuse, concomitant substance misuse, and the unmet behavioral health treatment needs of transgender and gender diverse adults.

BACKGROUND: Limited research has explored risk factors for opioid pain medication misuse, concomitant substance misuse, and the unmet behavioral health treatment (BHTx) needs of transgender and gender diverse (TGD) adults. METHODS: In 2019, TGD adults (N = 562) in Massachusetts and Rhode Island were purposively recruited and completed a psychosocial and behavioral health survey (95 % online; 5% in-person). Multivariable logistic regression was used to examine factors associated with past 12-month opioid pain medication misuse and unmet BHTx needs. RESULTS: Overall, 24.4 % of participants were trans women; 32.0 % trans men; and 43.6 % were non-binary. Past-year substance misuse included: marijuana (56.8 %), hazardous drinking (37.5 %), hallucinogens (9.8 %), benzodiazepines (8.2 %), and opioid pain medication (8.0 %). Among participants with past-year substance misuse and BHtx need (n = 326), 81.3 % received BHtx and 18.7 % had unmet BHtx needs. Being a trans woman, having HIV, stigma in healthcare, and number of substances misused were associated with increased odds of past-year opioid pain medication misuse; high social connectedness was associated with decreased odds of opioid pain medication misuse (p-values<0.05). Younger age, stigma in healthcare, and misusing opioid pain medications were associated with increased odds of unmet BHTx needs; post-traumatic stress disorder and family support were associated with decreased odds of unmet BHtx needs (p-values<0.05). CONCLUSIONS: Addressing disparities in opioid pain medication misuse among TGD people requires systematic improvements in healthcare access, including efforts to create TGD-inclusive BHtx environments with providers who are equipped to recognize and treat the social and structural drivers of TGD health inequities, including opioid pain medication misuse.

Transgender-specific developmental milestones and associated experiences of violence, discrimination, and stigma among Filipinx transgender women who are sexually active with men.

BACKGROUND: For transgender people, reaching transgender (trans)-specific developmental milestones, including recognizing and expressing one's identity, plays an integral role in overall health, wellbeing, and the pursuit of gender affirmation. Yet trans people continue to face minority stressors, including structural violence (i.e., discrimination, violence, and stigma), which may interfere with the achievement of these milestones. Among trans women specifically, however, potential associations between gender developmental milestones and structural violence are not well characterized in the literature. In a sample of Filipinx (i.e., an inclusive term for describing non-binary genders in the Philippines) trans women who are sexually active with men (trans-WSM), we thus sought to: (a) describe the mean ages at which gender developmental milestones occur and (b) examine the associations between structural violence and mean ages at which at which Filipinx trans-WSM experience trans-specific developmental milestones. METHODS: Using data from Project #ParaSaAtin, an online survey of Filipinx trans-WSM (n = 139), we mapped age-estimates per trans-specific milestones and then tested whether structural violence is associated with the mean age at which trans women experience trans-specific developmental milestones. RESULTS: Overall, participants who reported higher levels of discrimination, stigma, and violence also experienced a later age for nearly each milestone (i.e., initial self-awareness of transfeminine identity, transfeminine expression in private, transfeminine expression in public, first consensual oral/vaginal/anal sex with a cisgender male partner, first consensual oral/vaginal/anal sex with a cisgender male partner as a trans women, and hormone integration) (all p-values <0.05). Of note, the single exception to this pattern was the non-significant association between stigma and initial disclosure of transfeminine identification to another person. CONCLUSION: Results are consistent with psychological literature outlining a temporal sequence of developmental milestones among young trans-WSM. For young trans-WSM in the Philippines, data from this study demonstrate significant associations between structural violence and the achievement of developmental milestones. These findings highlight the need for trauma-informed, strengths-based programming and institutional policies that measure and mitigate anti-trans violence.
