HIV care continuum among cisgender and transgender women sex workers in Greater Kuala Lumpur, Malaysia.

An estimated 37,000 cisgender and transgender women work as sex workers in Malaysia, a population that has been disproportionately affected by the HIV epidemic. Although Malaysia provides no-cost antiretroviral therapy (ART) to people with HIV, little is known about sex workers' engagement in the HIV care continuum. We analyzed data from 57 HIV-infected cisgender women (n = 33) and transgender women (n = 24) sex workers from a respondent-driven sampling study on HIV prevalence among sex workers in Kuala Lumpur, Malaysia. We examined the proportion of women who were newly diagnosed with HIV, had a baseline CD-4 count test, were initiated and retained on antiretroviral treatment (ART). Overall, only 26.3% had ever been HIV tested and almost 60% were newly diagnosed. Only a small proportion of cisgender (15.2%) and transgender (12.5%) women were currently taking ART. Interventions to enhance sex workers' engagement in the HIV care continuum are urgently needed. Deployment of evidence-based strategies to improve linkage and retention in HIV care should be adapted to address the unique needs of this important key population.

Prevalence and Correlates of Active Amphetamine-Type Stimulant Use Among Female Sex Workers in Malaysia.

The use of amphetamine-type stimulants (ATS) has been associated with increased sexual risk behaviors and HIV transmission, among other adverse health outcomes. However, ATS use among female sex workers (FSWs) in Malaysia has not yet been characterized. We examined the prevalence and correlates associated with ATS use among Malaysian FSW. Between February and December 2016, 492 FSWs, including cisgender (n = 299) and transgender (n = 193) women, were recruited using respondent-driven sampling in Greater Kuala Lumpur, Malaysia. A structured questionnaire was used to collect demographic characteristics, sexual behaviors, ATS and other substance use, behavioral health issues, involvement in criminal justice, and experience of physical and sexual trauma. Logistic regression analyses were conducted to determine factors associated with active ATS use, defined as ATS use in the last 30 days. Nearly one-third (32.3%) of participants reported active ATS use. In the multivariable model, ATS use was associated with drug use during sex work (aOR = 17.10; 8.32-35.15), having moderate to severe level of substance use disorder (aOR = 3.38; 1.48-7.70), and engaging in sex work with multiple clients per day (two clients: aOR = 3.39; 1.36-8.46; three clients: aOR = 5.06; 1.81-14.10). A high prevalence of ATS use was documented in our sample. The presence of moderate to severe substance use disorder, the use of drugs during sex work activity, and having multiple sex work clients per day were significantly associated with active ATS use. Given these findings, prevention and harm reduction strategies need to be tailored to address the increasing ATS use and the associated adverse health consequences among FSWs in Malaysia.

Preexposure Prophylaxis for Women Across the Criminal Justice System: Implications for Policy and Practice.

Data that inform preexposure prophylaxis (PrEP) implementation for women involved in criminal justice (WICJ) systems are scarce. In a survey of PrEP attitudes, acceptability, and barriers across the criminal justice system, incarcerated women (n = 48) were more likely than WICJ on probation (n = 125) to be eligible for PrEP (29% vs. 15%; p = .04) and willing to take PrEP if offered (94% vs. 78%; p = .01). In multivariate models, PrEP eligibility directly correlated with being incarcerated (adjusted odds ratio [aOR] 4.81, 95% confidence interval [CI] 1.76-13.1) and inversely correlated with Hispanic/Latina ethnicity (aOR 0.31; 95% CI 0.10-0.96). Recent partner violence exposure was associated with PrEP eligibility (aOR 3.29; 95% CI 1.54-7.02) and discordant risk perception (aOR 2.36; 95% CI 1.18-4.70). Findings demonstrate high potential for PrEP for all WICJ, though implementation efforts will need to address partner violence.

Correlates of newly diagnosed HIV infection among cisgender women sex workers and transgender women sex workers in Greater Kuala Lumpur, Malaysia.

Globally, cisgender women sex workers (CWSWs) and transgender women sex workers (TWSWs) experience increased vulnerabilities to HIV infection. Unfortunately, there is limited data on the drivers of HIV infection in these two understudied populations, particularly in Southeast Asia. To better understand factors associated with HIV infection, we evaluated correlates of newly diagnosed HIV infection in these two populations in Greater Kuala Lumpur, Malaysia. A total of 469 women (CWSW: n = 283; TWSW: n = 186) were included in this study. Most participants who tested HIV+ were unaware of their infection (59.6%; n = 34/57). Separate binary and multivariable logistic regressions were conducted to identify correlates of newly diagnosed HIV in CWSWs and TWSWs. Among CWSWs, Chlamydia trachomatis (aOR = 5.66; p = 0.007) and lifetime use of ecstasy/MDMA (aOR = 5.34; p = 0.03) were associated with newly diagnosed HIV, while condomless vaginal sex with clients was associated with lower likelihood of HIV infection (aOR = 0.98; p = 0.01). Among TWSWs, being single (aOR = 6.76; p = 0.03), using mobile application to solicit clients (aOR = 25.33; p = 0.006), and having C. trachomatis infection (aOR = 88.22, p = 0.02) were associated with newly diagnosed HIV. Expansion of HIV/sexually transmitted infection screening is needed to increase detection of HIV and linkage to care for sex workers. Interventions to reduce HIV infection among CWSWs and TWSWs should be tailored to these populations' unique vulnerabilities.

Correlates of Recent HIV Testing Among Transgender Women in Greater Kuala Lumpur, Malaysia.

PURPOSE: In Malaysia, an estimated 9.7%-12.4% of transgender women (TW) are HIV positive, with higher estimates among those engaged in sex work. According to the 90-90-90 Joint United Nations Programme on HIV/AIDS strategy, HIV testing is the first crucial step in curbing the HIV epidemic. This study examines correlates of recent HIV testing among TW in Greater Kuala Lumpur, Malaysia. METHODS: TW (N = 199) in Greater Kuala Lumpur completed a survey on healthcare access and utilization, including HIV testing history. Bivariate logistic regression and penalized multivariate logistic regression were used to explore correlates of HIV testing in the last 12 months. RESULTS: Overall, 41.7% of TW reported having ever been tested for HIV. Among participants who were HIV negative or not sure of their HIV status (n = 187), only 18.7% (n = 35) had been tested for HIV in the last 12 months. The multivariate analysis indicated that having a primary care provider (PCP), being 26-40 years of age, and having higher mental health functioning were positively associated with recent HIV testing. Active amphetamine use and previous depression diagnosis were also associated with recent HIV testing. CONCLUSION: HIV testing is the first step in linking individuals to prevention and treatment interventions. Our findings suggest that having a PCP can improve engagement in HIV testing. Moreover, PCPs can serve as a valuable link to HIV treatment and prevention services. Current interventions that target social and behavioral risk factors for HIV, on their own, may be insufficient at engaging all HIV-vulnerable TW.

Prevalence of Human Immunodeficiency Virus and Sexually Transmitted Infections Among Cisgender and Transgender Women Sex Workers in Greater Kuala Lumpur, Malaysia: Results From a Respondent-Driven Sampling Study.

BACKGROUND: Sex workers face a disproportionate burden of human immunodeficiency virus (HIV) and sexually transmitted infections (STI) worldwide. For cisgender women sex workers (CWSW), global HIV prevalence is over 10%, whereas transgender women sex workers (TWSW) face an HIV burden of 19% to 27%. METHODS: We used respondent-driven sampling to recruit 492 sex workers, including CWSW (n = 299) and TWSW (n = 193) in Greater Kuala Lumpur, Malaysia. Participants completed an in-depth survey and were screened for HIV, syphilis, Chlamydia trachomatis, and Neisseria gonorrhoeae. Sample characteristics stratified by gender identity and interview site are presented. Bivariate analyses comparing CWSW and TWSW were conducted using independent samples t tests for continuous variables and χ tests for categorical variables. RESULTS: Pooled HIV prevalence was high (11.7%; 95% confidence interval [CI], 8.8-14.5), and was similar for CWSW (11.1%) and TWSW (12.4%). Rates of syphilis 25.5% (95% CI, 21.6-29.5), C. trachomatis (14.8%; 95% CI, 11.6-18.0) and N. gonorrhoeae (5.8%; 95% CI, 3.7-7.9) were also concerning. Both groups reported lifetime HIV testing (62.4%), but CWSW were less likely to have ever been HIV tested (54.5%) than TWSW (74.6%). Median time since last HIV test was 24 months. Previous screening for STI was low. Inconsistent condom use and drug use during sex work were not uncommon. CONCLUSIONS: High HIV and STI prevalence, coupled with infrequent HIV and STI screening, inconsistent condom use, and occupational drug use, underscore the need for expanded HIV and STI prevention, screening, and treatment efforts among CWSW and TWSW in Malaysia.

Innovative Program Delivery and Determinants of Frequent Visitation to a Mobile Medical Clinic in an Urban Setting.

The Community Health Care Van (CHCV) is a mobile medical clinic (MMC) that has served vulnerable populations in New Haven, Connecticut since 1993. This study explores utilization patterns to understand if certain populations frequently rely upon non-traditional health care within a representative MMC. Patient characteristics, services used, and visitation frequency were described and compared for 8,415 unique clients making 29,728 visits. Negative binomial regression was used to model the impact of specific indicators on visitation. Clients receiving buprenorphine had the highest visitation rates, with 2.09 visits per person-year. Increased CHCV visitation was positively associated with being foreign-born (additional 3.42 visits on average, p < .001), injection drug use (additional 1.69 visits on average, p < .001) and having hypertension (additional 1.09 visits on average, p < .001). As the Affordable Care Act has increased health insurance coverage, MMCs will continue their role in assisting entry into continuous health care and offering low-threshold acute care for urban vulnerable populations.

Gender identity, healthcare access, and risk reduction among Malaysia's mak nyah community.

Transgender women (TGW) face compounded levels of stigma and discrimination, resulting in multiple health risks and poor health outcomes. TGW identities are erased by forcing them into binary sex categories in society or treating them as men who have sex with men (MSM). In Malaysia, where both civil and religious law criminalise them for their identities, many TGW turn to sex work with inconsistent prevention methods, which increases their health risks. This qualitative study aims to understand how the identities of TGW sex workers shapes their healthcare utilisation patterns and harm reduction behaviours. In-depth, semi-structured interviews were conducted with 21 male-to-female transgender (mak nyah) sex workers in Malaysia. Interviews were transcribed, translated into English, and analysed using thematic coding. Results suggest that TGW identity is shaped at an early age followed by incorporation into the mak nyah community where TGW were assisted in gender transition and introduced to sex work. While healthcare was accessible, it failed to address the multiple healthcare needs of TGW. Pressure for gender-affirming health procedures and fear of HIV and sexually transmitted infection screening led to potentially hazardous health behaviours. These findings have implications for developing holistic, culturally sensitive prevention and healthcare services for TGW.

Strategies for hepatitis C testing and linkage to care for vulnerable populations: point-of-care and standard HCV testing in a mobile medical clinic.

Despite new Hepatitis C virus (HCV) therapeutic advances, challenges remain for HCV testing and linking patients to care. A point-of-care (POC) HCV antibody testing strategy was compared to traditional serological testing to determine patient preferences for type of testing and linkage to treatment in an innovative mobile medical clinic (MMC). From 2012 to 2013, all 1,345 MMC clients in New Haven, CT underwent a routine health assessment, including for HCV. Based on patient preferences, clients could select between standard phlebotomy or POC HCV testing, with results available in approximately 1 week versus 20 min, respectively. Outcomes included: (1) accepting HCV testing; (2) preference for rapid POC HCV testing; and (3) linkage to HCV care. All clients with reactive test results were referred to a HCV specialty clinic. Among the 438 (32.6 %) clients accepting HCV testing, HCV prevalence was 6.2 % (N = 27), and 209 (47.7 %) preferred POC testing. Significant correlates of accepting HCV testing was lower for the "baby boomer" generation (AOR 0.67; 95 % CI 0.46-0.97) and white race (AOR 0.55; 95 % CI 0.36-0.78) and higher for having had a prior STI diagnosis (AOR 5.03; 95 % CI 1.76-14.26), prior injection drug use (AOR 2.21; 95 % CI 1.12-4.46), and being US-born (AOR 1.76; 95 % CI 1.25-2.46). Those diagnosed with HCV and preferring POC testing (N = 16) were significantly more likely than those choosing standard testing (N = 11) to be linked to HCV care within 30 days (93.8 vs. 18.2 %; p < 0.0001). HCV testing is feasible in MMCs. While patients equally preferred POC and standard HCV testing strategies, HCV-infected patients choosing POC testing were significantly more likely to be linked to HCV treatment. Important differences in risk and background were associated with type of HCV testing strategy selected. HCV testing strategies should be balanced based on costs, convenience, and ability to link to HCV treatment.

Accessibility and utilization patterns of a mobile medical clinic among vulnerable populations.

We mapped mobile medical clinic (MMC) clients for spatial distribution of their self-reported locations and travel behaviors to better understand health-seeking and utilization patterns of medically vulnerable populations in Connecticut. Contrary to distance decay literature, we found that a small but significant proportion of clients was traveling substantial distances to receive repeat care at the MMC. Of 8404 total clients, 90.2% lived within 5 miles of a MMC site, yet mean utilization was highest (5.3 visits per client) among those living 11-20 miles of MMCs, primarily for those with substance use disorders. Of clients making >20 visits, 15.0% traveled >10 miles, suggesting that a significant minority of clients traveled to MMC sites because of their need-specific healthcare services, which are not only free but available at an acceptable and accommodating environment. The findings of this study contribute to the important research on healthcare utilization among vulnerable population by focusing on broader dimensions of accessibility in a setting where both mobile and fixed healthcare services coexist.

The burgeoning HIV/HCV syndemic in the urban Northeast: HCV, HIV, and HIV/HCV coinfection in an urban setting.

INTRODUCTION: Despite recommendations for generation-based HCV and once lifetime HIV screening, thousands of individuals in the U.S. still remain untested and undiagnosed. This cross-sectional study examines the correlates of HCV and HIV monoinfection and HIV/HCV coinfection in an urban Northeast setting. METHODS: Utilizing an electronic database from a mobile medical clinic in New Haven, CT from January 2003 to July 2011, 8,311 individuals underwent structured health assessment and screening for HIV and HCV. RESULTS: HIV [N = 601 (8.0%)] and HCV [N = 753 (10.1%)] infection were identified, and 197 (26.1%) of the 753 with HCV were coinfected with HIV. Both monoinfection and coinfection status were independently correlated with crack cocaine use and increasing age. HIV/HCV coinfection was correlated with men having sex with men (MSM) (AOR = 38.53, p<0.0080), shooting gallery use (AOR = 3.06, p<0.0070), and not completing high school (AOR = 2.51, p<0.0370). HCV monoinfection correlated with health insurance (AOR = 2.16, p<0.0020), domestic violence (AOR = 1.99, p<0.0070), and being Hispanic (AOR = 2.63, p<0.0001), while HIV monoinfection correlated with having had syphilis (AOR = 2.66, p<0.0001) and being Black (AOR = 1.73, p = 0.0010). CONCLUSIONS: Though HIV and HCV share common transmission risk behaviors, independent correlates with viral infection status in an urban Northeast setting are distinct and have important implications for surveillance, healthcare delivery, disease prevention, and clinical care.
