Syndemic theory and HIV-related risk among young transgender women: the role of multiple, co-occurring health problems and social marginalization.

OBJECTIVES We assessed whether multiple psychosocial factors are additive in their relationship to sexual risk behavior and self-reported HIV status (i.e., can be characterized as a syndemic) among young transgender women and the relationship of indicators of social marginalization to psychosocial factors. METHODS Participants (n = 151) were aged 15 to 24 years and lived in Chicago or Los Angeles. We collected data on psychosocial factors (low self-esteem, polysubstance use, victimization related to transgender identity, and intimate partner violence) and social marginalization indicators (history of commercial sex work, homelessness, and incarceration) through an interviewer-administered survey. RESULTS Syndemic factors were positively and additively related to sexual risk behavior and self-reported HIV infection. In addition, our syndemic index was significantly related to 2 indicators of social marginalization: a history of sex work and previous incarceration. CONCLUSIONS These findings provide evidence for a syndemic of co-occurring psychosocial and health problems in young transgender women, taking place in a context of social marginalization.

Transgender Female Youth and Sex Work: HIV Risk and a Comparison of Life Factors Related to Engagement in Sex Work

This study examined the HIV risk behaviors and life experiences of 151 transgender female youth, ages 15–24, in Los Angeles and Chicago. Descriptive analyses and logistic regression modeling were used to identify life factors associated with ever having engaged in sex work. Sixty-seven percent of participants had ever engaged in sex work and 19% self-reported being HIV positive. Many factors were significantly associated with sex work for this sample population. A final multivariate logistic regression model found that lower education status, homelessness, use of street drugs, and perceived social support remained significantly associated with sex work when controlling for other factors. Findings highlight the complex HIV risk environment and suggest a need for sex work initiation research for transgender female youth. HIV prevention efforts for this population need to include broad-based approaches that take into account individual, social, and community-level factors relevant to the lives of transgender female youth.

Correlates of HIV Infection Among Transfemales, San Francisco, 2010: Results From a Respondent-Driven Sampling Study

OBJECTIVES We evaluated the use of respondent-driven sampling (RDS) among a high-risk population of transfemales. We also obtained up-to-date epidemiological data on HIV infection and related correlates among this population. METHODS We evaluated the utility of RDS in recruiting a sample of 314 transfemales in San Francisco, California, from August to December 2010 by examining patterns of recruitment and assessing network sizes and equilibrium. We used RDS weights to conduct bivariate and multivariate analyses of correlates of HIV infection. RESULTS The sample had moderate homophily and reached equilibrium at the eighth wave of recruitment. Weighted HIV prevalence among transfemales was 39.5%. Being a transfemale of color, using injection drugs, and having low educational attainment were independently associated with HIV infection and having a high number of sexual partners and identifying as female were not. CONCLUSIONS RDS performed well and allowed for analyses that are generalizable to the population from which the sample was drawn. Transfemales in San Francisco are disproportionately affected by HIV compared with all other groups except men who have sex with men who also inject drugs.

Sexual Risk Taking Among Transgender Male-to-Female Youths With Different Partner Types

OBJECTIVES We examined associations between partner types (categorized as main, casual, or commercial) and sexual risk behaviors of sexually active male-to-female (transgender female) youths. METHODS We interviewed 120 transgender female youths aged 15 to 24 years recruited from clinics, community-based agencies, club and bar venues, referrals, and the streets of Los Angeles, California, and Chicago, Illinois. RESULTS Sexual risk behaviors varied by partner type. Transgender female youths were less likely to use condoms during receptive anal intercourse with their main partner and were less likely to use condoms with a main partner while under the influence of substances. Youth participants were also more likely to talk to a main partner about their HIV status. Our data identified no demographic or social factors that predicted condom use during receptive anal intercourse by partner type. CONCLUSIONS Research and interventions that focus on understanding and mitigating risk behaviors by partner type, especially those that tackle the unique risks incurred with main partners, may make important contributions to risk reduction among transgender female youths.

Prevalence and correlates of substance use among trans*female youth ages 16–24 years in the San Francisco Bay Area

BACKGROUND Substance use is highly prevalent among transgender (trans*) females and has been associated with negative health outcomes, including HIV infection. Little is known about psychosocial risk factors that may influence the onset of substance use among trans*female youth, which can contribute to health disparities during adulthood. METHODS We conducted a secondary data analysis of a study on HIV risk and resilience among trans*female youth (N=292). Prevalence of substance use was assessed and multivariable logistic regression models were used to examine the relationship between posttraumatic stress disorder (PTSD), psychological distress, gender-related discrimination, parental drug or alcohol problems (PDAP) and multiple substance use outcomes. RESULTS Most (69%) of the trans*female youth reported recent drug use. In multivariable analyses, those with PTSD had increased odds of drug use [AOR=1.94 (95% CI=1.09-3.44)]. Those who experienced gender-related discrimination had increased odds of drug use [AOR=2.28 (95% CI=1.17-4.44)], drug use concurrent with sex [AOR=2.35 (95% CI=1.11-4.98)] and use of multiple drugs [AOR=3.24 (95% CI=1.52-6.88)]. Those with psychological distress had increased odds of using multiple heavy drugs [AOR=2.27 (95% CI=1.01-5.12)]. Those with PDAP had increased odds of drugs use [AOR=2.62 (95% CI=1.43-4.82)], drug use concurrent with sex [AOR=2.01 (95% CI, 1.15-3.51)] and use of multiple drugs [AOR=2.10 (95% CI=1.22-3.62)]. CONCLUSIONS Substance use is highly prevalent among trans*female youth and was significantly associated with psychosocial risk factors. In order to effectively address substance use among trans*female youth, efforts must address coping related to gender-based discrimination and trauma. Furthermore, structural level interventions aiming to reduce stigma and gender-identity discrimination might also be effective.

HIV treatment cascade among transgender women in a San Francisco respondent driven sampling study

Objective Male-to-female transgender women (transwomen) have a disproportionate burden of HIV. We sought to estimate HIV treatment cascade indicators among transwomen in San Francisco. Methods We conducted a respondent driven sampling (RDS) study of 314 transwomen from August to December 2010. The study tested participants for HIV and collected self-reported data on linkage and access to care, viral load and antiretroviral treatment (ART). We derived population-based estimates and 95% CIs of cascade indicators using sampling weights based on established RDS methods. We conducted RDS-weighted logistic regression analyses to evaluate correlates of being on ART and being virologically suppressed (viral load ≤200 copies/mL). Results The RDS-weighted population-based estimate of HIV prevalence was 39% (95% CI 32% to 48%) among transwomen tested for HIV. Among HIV-positive transwomen, 77% (95% CI 70% to 93%) reported being linked to care within 3 months of diagnosis and 87% (95% CI 76% to 98%) accessed care in the past 6 months. In addition, 65% (95% CI 54% to 75%) were on ART, and less than half (44%; 95% CI 21% to 58%) were virologically suppressed. Housing instability was associated with lower odds of being on ART and being virologically suppressed. Conclusions We observed a high prevalence of HIV in our population-based estimates of transwomen in San Francisco, coupled with modest ART use and low virological suppression rates, indicating high potential for forward transmission. Poor HIV treatment outcomes were consistently associated with housing instability. These data suggest that multi-level efforts, including efforts to address housing insecurity, are urgently needed to ameliorate disparities in HIV clinical outcomes among transwomen and reduce secondary HIV transmission to their partners.

Connecting the dots: examining transgender women's utilization of transition-related medical care and associations with mental health, substance use, and HIV.

Findings on access to general healthcare for transgender people have emerged, but little is known about access to transition-related medical care for transwomen (i.e., hormones, breast augmentation, and genital surgery). Transgender women have low access to general medical care and are disproportionately at risk for substance use, mental illness, and HIV. We conducted an analysis to determine if utilization of transition-related medical care is a protective factor for health risks to transgender women and to investigate if care differs by important demographic factors and HIV status. A secondary analysis was conducted using data from a 2010 HIV surveillance study using respondent-driven sampling to recruit 314 transwomen in San Francisco. Survey-corrected logistic regression models were used to estimate odds ratios for six psychosocial health problems—binge drinking, injection drug use, anxiety, depression, suicidal ideation, and high-risk intercourse—comparing various levels of utilization of transition-related medical care. Odds ratios were also calculated to determine if utilization of transition-related medical care was related to less overlap of risk domains. We found that Latina and African American transwomen had significantly lower estimated utilization of breast augmentation and genital surgery, as did transwomen who identified as transgender rather than female. Overall, utilization of transition-related medical care was associated with significantly lower estimated odds of suicidal ideation, binge drinking, and non-injection drug use. Findings suggest that utilization of transition-related medical care may reduce risk for mental health problems, especially suicidal ideation, and substance use among transwomen. Yet, important racial/ethnic and gender identity disparities in utilization of transition-related medical care need to be addressed.

Differential HIV Risk for Racial/Ethnic Minority Trans*female Youths and Socioeconomic Disparities in Housing, Residential Stability, and Education

OBJECTIVES We examined HIV prevalence and risk behaviors of 282 trans*female youths aged 16 to 24 years participating in the San Francisco Bay Area, California, SHINE study from 2012 to 2013 to determine differences between racial/ethnic minority and White youths. METHODS We conducted the χ(2) test to determine distributional differences between racial/ethnic minority and White participants in sociodemographic factors, HIV-related risk behaviors, and syndemic factors. RESULTS Of the trans*female youths, 4.8% were HIV positive. Racial/ethnic minority and White trans*female youths differed significantly in gender identity and sexual orientation. Racial/ethnic minority youths also had significantly lower educational attainment, were less likely to have lived with their parents of origin as a child, and were significantly more likely to engage in recent condomless anal intercourse than were Whites. CONCLUSIONS Efforts to assess the impact of multiple-minority stress on racial/minority trans*female youths are needed imminently, and prevention efforts must address macrolevel disparities for trans*female youths, especially those from racial/ethnic minority groups, to reduce these disparities and prevent incident cases of HIV.

Stigma and HIV risk among Metis in Nepal

Similar to other parts of Asia, the HIV epidemic in Nepal is concentrated among a small number of groups, including transgender people, or Metis. This study was conducted to explore the social context of stigma among Metis in Nepal to better understand their risk for HIV. Fourteen in-depth interviews were conducted with Metis in Kathmandu, Nepal. We found that stigma from families leading to rural-urban migration exposed Metis to discrimination from law enforcement, employers and sexual partners, which influenced their risk for HIV. Specific HIV-related risks identified were rape by law enforcement officers, inconsistent condom use and high reported numbers of sexual partners. These data point to an immediate need to work with law enforcement to reduce violence targeting Metis. HIV prevention, housing and employment outreach to Metis in rural areas and those who migrate to urban areas is also needed. Finally, there is a need for more research to determine the prevalence of HIV among Metis, to explore risk within sexual networks and to better understand of the relationship between Metis and their families in order to develop future programmes and interventions.

Parental support and condom use among transgender female youth.

&NA; Evidence suggests that transgender female youth (TFY), much like their adult transgender female peers, are at high risk for HIV. Yet little attention has been given to important developmental experiences of TFY that may impact HIV risk for this youth population. The overall purpose of this study was to explore HIV risk in TFY. A reoccurring theme from the qualitative data was the importance of parents. To better understand the impact of parents on HIV risk among TFY, in‐depth individual interview data from 21 TFY in Los Angeles and Chicago were analyzed, suggesting a potential link between HIV‐related risk behavior and parental support. Youth with parental support in this sample reported regular condom use, while those without such support reported inconsistent condom use. Implications for the unique research and interventions needs of TFY related to parental support and sexual risk behaviors are discussed.
