HIV's Syndemic Links With Mental Health, Substance Use, and Violence in an Environment of Stigma and Disparities in Japan

Mental health service use and shortages among a cohort of women living with HIV in Canada

BACKGROUND

The prevalence of mental health conditions among women with HIV in Canada ranges between 29.5% and 57.4%, highlighting the need for accessible mental health care. We aimed to (1) describe the availability and use of mental health services among women with HIV and (2) identify characteristics associated with reporting that shortages of these services presented a problem in their care.

METHODS

Baseline data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study were analysed. Self-reported availability and use of mental health services were examined using descriptive statistics. Participants indicated whether a lack of mental health support was a problem in their care. Logistic regression models were constructed to determine associations between sociodemographic, clinical, and psychosocial characteristics and reported problematic shortages.

RESULTS

Of 1422 women, 26.7% (n = 380) used mental health services in the last year, which most accessed through their HIV clinic. Thirty-eight percent (n = 541) reported that a shortage of mental health support was a problem in their care. Among this subset, 22.1% (n = 119) used services at their HIV clinic, 26.5% (n = 143) reported available services but did not use them, and 51.4% (n = 277) either indicated that these services were unavailable, did not know if such services were available, or were unengaged in HIV care. Factors associated with reporting problematic shortages included rural residence [adjusted odds ratio (aOR): 1.69, 95% confidence interval (CI): 1.03-2.77], higher education level (aOR: 1.43, 95% CI: 1.02-2.02), and higher HIV stigma score (aOR: 1.03, 95% CI: 1.02-1.03). Conversely, African/Caribbean/Black identity (aOR: 0.37, 95% CI: 0.26-0.54), history of recreational drug use (aOR: 0.56, 95% CI: 0.39-0.81), and Quebec residence (aOR: 0.69, 95% CI: 0.50-0.96) were associated with lower odds of reporting service shortages.

CONCLUSION

Our findings highlight the HIV clinic as the primary location of mental health service use. However, existing services may not be sufficient to reach all patients or meet specific needs. Furthermore, the low uptake among those reporting a shortage suggests a lack of connection to services or patient knowledge about their availability. Characteristics associated with reporting shortages reflect geographic and socioeconomic disparities that must be accounted for in future service design.

Disparities in HIV incidence and mortality rates between Japanese nationals and international migrants before and during the COVID-19 pandemic: evidence from Japan's national HIV surveillance data (2018-2021)

Migrants often encounter heightened health risks during crises. We analysed the disparities in the burden of HIV between Japanese nationals and international migrants in Japan by comparing new HIV infections, AIDS cases, and HIV-related deaths between 2018-2019 (pre-COVID-19) and 2020-2021 (during the COVID-19 pandemic). Between 2018 and 2021, 4,705 new HIV infections were reported in Japan (2,813 Japanese nationals and 522 international migrants). Additionally, 1,370 AIDS cases (1,188 Japanese nationals, 182 international migrants) were recorded, representing 29.1% of the total. Comparative analysis of HIV incidence and mortality rates between Japanese nationals and international migrants indicates elevated disparities: During the COVID-19 pandemic, the HIV incidence rate among Japanese nationals decreased from 1.8 to 1.5 cases/100,000 people, while the rate among international migrants remained high at 12.8 cases/100,000 people. The AIDS incidence also increased for international migrants from 2.8 to 3.8 per 100,000 people, while Japanese nationals maintained a low at 0.5 per 100,000 people. International migrants living with HIV experienced a significantly younger age at death due to HIV-related illness (coefficient = -11.7, p < .01). The COVID-19 pandemic may have exacerbated the disparities with more international migrants living with HIV being diagnosed late and with less precise reporting. Investment in more equitable HIV care is warranted.

HIV prevalence among transgender women in Northeast Brazil – Findings from two Respondent Driven Sampling studies

Background

The HIV epidemic still high among key-populations in Brazil, especially among transgender women (TGW). The aim of this study was to investigate the prevalence of HIV infection among TGW and to analyze factors associated with HIV seropositivity across two cross-sectional surveys conducted in Salvador, Bahia, one of the largest urban centers of Brazil.

Methods

The studies were conducted between 2014 and 2016 and 2016-2017 and employed Respondent-Driven Sampling (RDS) sampling, comprising 127 and 161 TGW residents of Salvador, Bahia. The outcome was the positive rapid antigen testing for HIV infection. Odds ratios (OR) and 95% confidence intervals (95%CI) were obtained using binomial logistic regression.

Results

The HIV prevalence was 9.0% (95%CI: 4.2-18.2) and 24.3% (95%CI: 16.2-34.9). In the first study, factors associated with HIV prevalence were experiencing discrimination by the family (OR 8.22; 95%CI: 1.49-45.48) and by neighbors (OR 6.55; 95%CI: 1.12-38.14) as well as having syphilis (OR 6.56; 95%CI:1.11-38.65); in the subsequent study gender-based discrimination (OR 8.65; 95%CI:1.45-51.59) and having syphilis (OR 3.13; 95%CI: 1.45-51.59) were associated with testing positive for HIV.

Conclusion

We found disproportionately high HIV prevalence among TGW, which underscores the context of vulnerability for this population. The data point to the urgency for intensification and expansion of access to HIV prevention and strategies to stop discrimination in health care and services for this population.

New strategies for prevention of HIV among Japanese men who have sex with men: a mathematical model

HIV prevalence in Japan continues to increase among men who have sex with men (MSM). We built a mathematical model to describe the HIV epidemic, including acute infection and pre-exposure prophylaxis (PrEP), and projected the model to 2050. We compared current testing and treatment policies, a scenario where Japan achieves UNAIDS 90-90-90 targets, three PrEP scenarios defined by different coverage levels of 25%, 50%, and 75% among the 20% of MSM with the highest risk behavior, and combinations of these scenarios. With no change in interventions prevalence of HIV among MSM will rise to 9.0% in 2050. If Japan achieves full UNAIDS 90-90-90 targets, 84.9% of these infections would be averted. Under 50% PrEP with no expansion of testing and treatment, prevalence will reach 2.6% and 62.1% of infections would be averted by 2050. If in addition UNAIDS 90-90-90 goals are achieved, 92.7% of HIV infections would be prevented by 2050. All interventions tested in this model were cost-saving relative to the base case. Both PrEP and enhanced ART strategies can be cost-saving, and if Japan enhances its testing program for MSM and introduces PrEP, it has the potential to effectively eliminate new infections in the next 30 years.

Depression, injecting drug use, and risky sexual behavior syndemic among women who inject drugs in Kenya: a cross-sectional survey

BACKGROUND

Injecting drug use (IDU) is a key driver of the HIV epidemic particularly when individuals experience psychosocial conditions and risky sexual behavior in a syndemic manner. This study sets out to assess evidence of a syndemic pattern of psychosocial conditions (IDU, depression, intimate partner violence (IPV)) on one the hand and risky sexual behavior on the other while accounting for the socio-economic disadvantage among women who inject drugs (WWID) in low-income urban settings in Kenya.

METHODS

Using a cross-sectional study design, this study recruited 306 WWIDs from two sites in Nairobi between January 2017 and July 2017. Multiple methodologies including descriptive analyses of co-occurrences of psychosocial conditions at the individual level, standard logistic regression analyses to examine relationships and interactions within and between psychosocial conditions and risky sexual behavior, and classification trees algorithm for predictive modeling via machine learning were employed.

RESULTS

The prevalence of the psychosocial conditions was as follows: IDU, 88%; depression, 77.1%; and IPV, 84%. The prevalence of risky sexual behavior was 69.3%. IDU and depression were related to each other (P < 0.05) and each of them with risky sexual behavior (P < 0.05). The highest 2-way and 3-way co-occurrence of conditions were reported in IDU and depression (72%) and in IDU, depression, and risky sexual behavior (62%), respectively, indicating clustering of the conditions at the individual level. Further, each additional psychosocial condition (IDU and depression) was associated with sixfold odds (P = 0.000) of having risky sexual behavior suggesting a dose-response relationship. Logistic regression analyses incorporating multiplicative interactive effects returned three significant variables (P < 0.05): IDU*depression interaction effect, "Age when delivered the first child," and "Income." Classification tree modeling represented a 5-level interaction analysis with IDU and depression predicted to have the highest influence on risky sexual behavior.

CONCLUSION

Findings provide possible evidence of a syndemic pattern involving IDU, depression, and risky sexual behavior suggesting the need for an integrated approach to the implementation of harm reduction interventions among WWID in low-income urban settings in Kenya. This work highlights the need for further studies to authenticate the findings and to characterize pathways in the syndemic development in WWID.

Stigma and discrimination related to gender identity and vulnerability to HIV/AIDS among transgender women: a systematic review

HIV prevalence among transgender women is disproportional when compared to the general population in various countries. Stigma and discrimination based on gender identity have frequently been associated with vulnerability to HIV/AIDS. The objective was to conduct a systematic literature review to analyze the relationship between stigma and discrimination related to gender identity in transgender women and vulnerability to HIV/AIDS. This systematic literature review involved the stages of identification, compilation, analysis, and interpretation of results of studies found in five databases: PubMed, Scopus, Web of Science, Science Direct, and LILACS. No publication time period was determined in advance for this review. The studies were assessed according to the inclusion and exclusion criteria. The review included articles in English, Portuguese, or Spanish that related stigma and discrimination to transgender women's vulnerability to HIV. We found 41 studies, mostly qualitative, published from 2004 to 2018, and categorized in three dimensions of stigma: individual, interpersonal, and structural. The data highlighted that the effects of stigma related to gender identity, such as violence, discrimination, and transphobia, are structuring elements in transgender women's vulnerability to HIV/AIDS. The studies showed a relationship between stigma and discrimination and transgender women's vulnerability to HIV/AIDS and indicated the need for public policies to fight discrimination in society.

Syndemics and HIV-related sexual risk among men who have sex with men in India: influences of stigma and resilience

Using syndemics theory as a framework, we explored the experience of men who have sex with men in India in relation to four syndemic conditions (depression, alcohol use, internalised homonegativity and violence victimisation) and to understand their resilience resources. Five focus groups were conducted among a purposive sample of diverse men along with seven key informant interviews with HIV service providers. Participants' narratives suggested various pathways by which syndemic conditions interact with one another to sequentially or concurrently increase HIV risk. Experiences of discrimination and violence from a range of perpetrators (family, ruffians and police) contributed to internalised homonegativity and/or depression, which in turn led some men to use alcohol as a coping strategy. Stigma related to same-sex sexuality, gender non-conformity and sex work contributed to the production of one or more syndemic conditions. While rejection by family and male regular partners contributed to depression/alcohol use, support from family, regular partners and peers served as resources of resilience. In India, HIV prevention and health promotion efforts among men who have sex with men could be strengthened by multi-level multi-component interventions to reduce intersectional/intersecting stigma, address syndemic conditions and foster resilience - especially by promoting family acceptance and peer support.

Factors Affecting Sexual History Taking in a Health Center Serving Homeless Persons

Low rates of documentation of sexual histories have been reported and research on sexual history taking (SHT) has focused on the content of, barriers to collecting, and interventions to improve documentation of sexual histories. Absent from this literature is an understanding of the contextual factors affecting SHT. To address this gap, a focused ethnography of one health center was conducted. Data were collected through observations of health care encounters and interviews with health care providers (HCPs). No SHT was observed and this was likely influenced by patients' characteristics, communication between patients and HCPs, the prioritization of patients' basic needs, and time constraints imposed upon encounters. Given that the health center studied serves patients experiencing homelessness, behavioral health concerns, and opioid use disorder, findings illuminate areas for future inquiry into a patient population affected by social as well as physiologic determinants of health and potentially at high risk for adverse sexual health outcomes.

Estigma e resistência entre travestis e mulheres transexuais em Salvador, Bahia, Brasil

Resumo: Trata-se de um estudo qualitativo, com base na análise de narrativas produzidas por travestis e mulheres transexuais em Salvador, Bahia, Brasil, com o objetivo de analisar suas experiências de estigmatização, descrevendo acontecimentos, atores e contextos que marcam as suas trajetórias de vida, e também compreender a relação entre o estigma e suas performances femininas. As narrativas são provenientes de 19 entrevistas em profundidade realizadas ao longo de um inquérito epidemiológico. Foram orientadas por um roteiro prévio que explorou a produção de narrativas sobre as experiências e modos de vida das travestis e mulheres transexuais na cidade de Salvador. As histórias de vida que emergiram do campo foram transcritas e analisadas sob uma perspectiva teórico-narrativa. Observou-se que muitas travestis e mulheres transexuais apresentaram em suas narrativas a descrição de uma performance de gênero “afeminada”, que é identificada desde à infância por membros da família e da comunidade. Essa performance é apresentada como uma insubordinação ao poder estabelecido pelo sistema jurídico da sociedade heteronormativa. O processo de estigmatização começa a operar quando as expectativas sociais sobre a coerência entre “sexo biológico” e “performance de gênero” são frustradas nas interações sociais, submetendo as pessoas à discriminação e violência. Desse modo, o processo de estigmatização é operado por meio do poder exercido pelas leis da heterossexualidade compulsória sobre os corpos. Entretanto, durante as trajetórias de vida das travestis e mulheres transexuais, estratégias de resistência contra o estigma são produzidas com o potencial de transformação dos quadros estabelecidos.

Gender-based discrimination and unprotected receptive anal intercourse among transgender women in Brazil: A mixed methods study

INTRODUCTION

Discrimination related to gender identity may directly influence vulnerability to HIV through increased exposure to unprotected receptive anal intercourse (URAI). Little is known about the relationship between gender-based discrimination (GBD) and URAI with stable partners among transgender women.

METHODS

This mixed-methods research began with a cross-sectional survey conducted between 2014 and 2016 with transgender women in Salvador, the capital city in one of the poorest regions in Brazil. Respondent-driven sampling was used to recruit the study population. GBD was defined through Latent Class Analysis. Additionally, 19 semi-structured interviews with participants were transcribed and analyzed through thematic content analysis.

RESULTS

URAI with stable partners was commonly reported (37.3%). GDB was positively associated with URAI among stable partners (OR = 6.47; IC 95%: 1.67-25.02). The analysis of the interviews illustrated how GBD impacted transgender women in diverse ways. Experiences with GBD perpetrated by the family often initiated a trajectory of economic vulnerability that led many to engage in survival sex work. The constant experience with GBD contributed to participants feeling an immense sense of trust with their stable partners, ultimately diminished their desire to use condoms. Further, the high frequency of GBD contributed to poor mental health overall, though some participants said engagement in transgender advocacy efforts provided a vital source of resilience and support.

CONCLUSION

Our mixed-method study capitalizes upon the strengths of diverse data sets to produce a holistic understanding of GBD and URAI with stable partners. Furthermore, by confirming the association between greater GBD and URAI, we have demonstrated how GBD can impact condom negotiation in diverse relationships.

HIV Pre-Exposure Prophylaxis and Postexposure Prophylaxis in Japan: Context of Use and Directions for Future Research and Action

Biomedical HIV prevention strategies are playing an increasingly prominent role in addressing HIV epidemics globally, but little is known about their use in Japan, where persistent HIV disparities and a recently stable, but not declining, national epidemic indicate the need for evolving approaches. We conducted an ethnographic study to determine the context of pre-exposure prophylaxis (PrEP) and postexposure prophylaxis (PEP) use and to identify directions for future research and action in Japan. We used data from observational fieldwork in the Kansai region and Tokyo Metropolitan Area (n = 178 persons observed), qualitative interviews (n = 32), documents and web-based data sources (n = 321), and email correspondences (n = 9) in the period 2013-2016. Drug approvals by Japan's regulatory agencies, insurance coverage for medications, and policies by healthcare institutions and government agencies were the main factors affecting PrEP and PEP legality, use, and awareness. Awareness and the observable presence of PrEP and PEP were very limited, particularly at the community level. PrEP and PEP held appeal for Japanese scientists and activists, and for study participants who represented various other stakeholder groups; however, significant concerns prevented open endorsements. Japanese health officials should prioritize a national discussion, weigh empirical evidence, and strongly consider formal approval of antiretroviral (ARV) medications for use in PrEP and both occupational and nonoccupational PEP. Once approved, social marketing campaigns can be used to advertise widely and increase awareness. Future research would benefit from theoretical grounding in a diffusion of innovations framework. These findings can inform current and future ARV-based prevention strategies at a critical time in the international conversation.

HIV in Japan: Epidemiologic puzzles and ethnographic explanations

Japan is widely perceived to have a low level of HIV occurrence; however, its HIV epidemics also have been the subject of considerable misunderstanding globally. I used a ground truthing conceptual framework to meet two aims: first, to determine how accurately official surveillance data represented Japan's two largest epidemics (urban Kansai and Tokyo) as understood and experienced on the ground; and second, to identify explanations for why the HIV epidemics were unfolding as officially reported. I used primarily ethnographic methods while drawing upon epidemiology, and compared government surveillance data to observations at community and institutional sites (459 pages of field notes; 175 persons observed), qualitative interviews with stakeholders in local HIV epidemics (n = 32), and document research (n = 116). This revealed seven epidemiologic puzzles involving officially reported trends and conspicuously missing information. Ethnographically grounded explanations are presented for each. These included factors driving the epidemics, which ranged from waning government and public attention to HIV, to gaps in sex education and disruptive leadership changes in public institutions approximately every two years. Factors constraining the epidemics also contributed to explanations. These ranged from subsidized medical treatment for most people living with HIV, to strong partnerships between government and a well-developed, non-governmental sector of HIV interventionists, and protective norms and built environments in the sex industry. Local and regional HIV epidemics were experienced and understood as worse than government reports indicated, and ground-level data often contradicted official knowledge. Results thus call into question epidemiologic trends, including recent stabilization of the national epidemic, and suggest the need for revisions to the surveillance system and strategies that address factors driving and constraining the epidemics. Based upon its utility in the current study, ground truthing has value as a conceptual framework for research and shows promise for future theoretical development.
