Safe Injection Self-Efficacy is Associated with HCV and HIV Seropositivity Among People Who Inject Drugs in the San Diego-Tijuana Border Region.

Safe injection self-efficacy (SISE) is negatively associated with injection risk behaviors among people who inject drugs (PWID) but has not been examined in differing risk environments. We compared responses to a validated SISE scale between PWID in San Diego, California and Tijuana, Mexico, and examine correlates of SISE among PWID in Tijuana. PWID were recruited via street outreach for a longitudinal cohort study from October 2020-September 2021. We compared SISE scale items by city. Due to low variability in SISE scores among San Diego residents, we restricted analysis of factors associated with SISE to Tijuana residents and identified correlates of SISE score levels (low, medium, high) using ordinal logistic regression. Of 474 participants, most were male (74%), Latinx (78%) and Tijuana residents (73%). Mean age was 44. Mean SISE scores among San Diego residents were high (3.46 of 4 maximum) relative to Tijuana residents (mean: 1.93). Among Tijuana residents, White race and having previously resided in San Diego were associated with higher SISE scores. HCV and HIV seropositivity, homelessness, fentanyl use, polysubstance co-injection, and greater injection frequency were associated with lower SISE scores. We found profound inequalities between Tijuana and San Diego SISE, likely attributable to differential risk environments. Associations with fentanyl and polysubstance co-injection, injection frequency, and both HIV and HCV seropositivity suggest that SISE contribute to blood-borne infection transmission risks in Tijuana. SISE reflects an actionable intervention target to reduce injection risk behaviors, but structural interventions are required to change the risk environment.

RESUMEN: La autoeficacia de inyección segura (SISE, por sus siglas en inglés) se asocia negativamente con conductas de riesgo de inyección entre las personas que se inyectan drogas (PWID, por sus siglas en inglés), pero no se ha examinado en diferentes entornos de riesgo. Comparamos las respuestas a una escala validada de SISE entre PWID en San Diego, California, y Tijuana, México, y examinamos los correlatos de SISE entre PWID en Tijuana. Participantes fueron reclutados por medio de alcance callejero para un estudio de cohorte longitudinal entre octubre 2020 ­septiembre de 2021. Comparamos los ítems de la escala SISE por ciudad. Debido a la baja variabilidad en los puntajes SISE entre los residentes de San Diego, restringimos el análisis de factores asociados con SISE a los residentes de Tijuana e identificamos factores correlacionados con niveles de SISE (bajo, medio, alto) mediante regresión logística ordinal. De 474 participantes, la mayoría eran hombres (74%), latinx (78%) y residentes de Tijuana (73%). La edad promedio fue de 44 años. Los puntajes medios de SISE entre los residentes de San Diego fueron altos (3.46 de un máximo de 4) en comparación con los residentes de Tijuana (media: 1.93). Entre los residentes de Tijuana, la raza blanca y haber residido previamente en San Diego se asociaron con puntajes más altos de SISE. La seropositividad para HCV y VIH, la falta de vivienda, el uso de fentanilo, la co-inyección de múltiples sustancias y una mayor frecuencia de inyecciónes se asociaron con puntajes más bajos de SISE. Encontramos profundas desigualdades entre SISE en Tijuana y San Diego, probablemente atribuibles a diferentes entornos de riesgo. Las asociaciones con fentanilo y la co-inyección de múltiples sustancias, la frecuencia de inyección y la seropositividad tanto para VIH como para HCV sugieren que SISE contribuye a los riesgos de transmisión de infecciones transmitidas por la sangre en Tijuana. SISE refleja un objetivo de intervención accionable para reducir las conductas de riesgo de inyección, pero se requieren intervenciones estructurales para cambiar el entorno de riesgo.

Water, sanitation, and hygiene access among people who inject drugs in Tijuana and San Diego in 2020-2021: a cross-sectional study.

BACKGROUND: Water, sanitation, and hygiene (WASH) access is critical to public health and human dignity. People who inject drugs (PWID) experience stigma and structural violence that may limit WASH access. Few studies have assessed WASH access, insecurity, and inequities among PWID. We describe WASH access, social and geographic inequalities, and factors associated with WASH insecurity among PWID in the Tijuana-San Diego metropolitan area. METHODS: In this cross-sectional binational study, we interviewed PWID (age 18+) in 2020-2021 about WASH access and insecurity. City of residence (Tijuana/San Diego) and housing status were considered as independent variables to describe key WASH access outcomes and to assess as factors associated with WASH insecurity outcomes. Measures of association between outcomes and independent variables were assessed using log modified-Poisson regression models adjusting for covariates. RESULTS: Of 586 PWID (202 Tijuana; 384 San Diego), 89% reported basic access to drinking water, 38% had basic hand hygiene, 28% basic sanitation, and 46% access to bathing, and 38% reported recent open defecation. Participants residing in Tijuana reported significantly higher insecurity in accessing basic drinking water (aRR: 1.68, 95%CI: 1.02-2.76), basic hygiene (aRR: 1.45, 95%CI: 1.28-1.64), and bathing (aRR: 1.21, 95%CI: 1.06-1.39) than those living in San Diego. Participants experiencing unsheltered homelessness experienced significantly higher insecurity in accessing basic drinking water (aRR: 2.03, 95%CI: 1.07-3.86), basic sanitation (aRR: 1.68, 95%CI: 1.48, 1.92), bathing (aRR: 1.84, 95%CI: 1.52-2.22), and improved water sources for cleaning wounds (aRR: 3.12, 95%CI: 1.55-6.29) and for preparing drugs (aRR: 2.58, 95%CI: 1.36-4.89) than participants living in permanent housing. CONCLUSION: WASH access among PWID in the Tijuana-San Diego metropolitan area was low by international standards and lower than the national averages in both countries. Homelessness was significantly associated with WASH insecurity in this population. Concentrated efforts are needed to guarantee continuously available WASH services for PWID-especially those who are unsheltered.

The association between depression and alcohol use among pregnant adults in the USA.

BACKGROUND: The prevalence of alcohol use among pregnant women aged 18-44 years old increased in recent years. The influence of mental health issues on an individual's likelihood to use alcohol during pregnancy has not been thoroughly investigated. This study will examine the association between experiencing a major depressive episode (MDE) in the past year and past-month alcohol use among pregnant women using the 2011-2020 National Survey on Drug Use and Health (NSDUH). METHODS: Pregnant women between the ages of 18 and 44 years old were included in the study for analysis. Multivariable logistic regression analysis was used to examine the association between past-year MDE and past-month alcohol use adjusting for age, race/ethnicity, marital status, and employment status. Additional logistic regression analysis was performed to investigate whether this relationship differed by trimester of pregnancy. RESULTS: A total of 6745 participants were included in the analytic sample. The prevalence of past-year MDE and past-month alcohol use was 7.67% and 9.15% respectively. Logistic regression analysis showed past-year MDE was significantly associated with past-month alcohol use in pregnant women adjusting for age, race/ethnicity, marital status, and employment status (aOR = 1.96; 95% CI, 1.34-2.87). This relationship became stronger in second and third trimesters of pregnancy. CONCLUSIONS: This study showed a positive association between MDE and past-month alcohol use among pregnant women, with strongest effect estimates in the third trimester. These findings may inform approaches for improved screening guidelines and health education for individuals who may be at higher risk of prenatal alcohol use.

Pandemic-related challenges accessing food and primary healthcare among sex workers during the COVID-19 pandemic: findings from a community-based cohort in Vancouver, Canada.

INTRODUCTION: Globally, the COVID-19 pandemic upended healthcare services and created economic vulnerability for many. Criminalization of sex work meant sex workers were largely ineligible for Canada's government-based financial pandemic relief, the Canadian Emergency Response Benefit. Sex workers' loss of income and inability to access financial support services during the pandemic resulted in many unable to pay rent or mortgage, and in need of assistance with basic needs items including food. Little is known about the unique experiences of sex workers who faced challenges in accessing food during the pandemic and its impact on healthcare access. Thus, we aimed to identify the association between pandemic-related challenges accessing food and primary healthcare among sex workers. METHODS: Prospective data were drawn from a cohort of women sex workers in Vancouver, Canada (An Evaluation of Sex Workers' Health Access, AESHA; 2010-present). Data were collected via questionnaires administered bi-annually from October 2020-August 2021. We used univariate and multivariable logistic regression with generalized estimating equations to assess the association between pandemic-related challenges accessing food and challenges accessing primary healthcare over the study period. RESULTS: Of 170 participants, 41% experienced pandemic-related challenges in accessing food and 26% reported challenges accessing healthcare. Median age was 45 years (IQR:36-53), 56% were of Indigenous ancestry, 86% experienced intimate partner violence in the last six months, and 62% reported non-injection substance use in the last six months. Experiencing pandemic-related challenges accessing food was positively associated with challenges accessing primary healthcare (Adjusted Odds Ratio: 1.99, 95% Confidence Interval: 1.02-3.88) after adjustment for confounders. CONCLUSIONS: Findings provide insight about the potential role community-based healthcare delivery settings (e.g., community clinics) can play in ameliorating access to basic needs such as food among those who are highly marginalized. Future pandemic response efforts should also take the most marginalized populations' needs into consideration by establishing strategies to ensure continuity of essential services providing food and other basic needs. Lastly, policies are needed establishing basic income support and improve access to food resources for marginalized women in times of crisis.

How immigration shapes health disadvantages and what healthcare organizations can do to deliver more equitable care.

That immigration is a determinant of health and that immigration systems themselves contribute to structural disadvantage remains under-addressed within healthcare in Canada. This article offers context for how immigration shapes health, and recommendations for how health systems can be better prepared to respond to the diverse needs of immigrants and migrants (together referred to as im/migrants), based on a community-based research project in British Columbia. Findings call attention to the varied and intersecting ways in which immigration status, access to health insurance, language, experiences of trauma and discrimination, lack of support for health system limits access to healthcare, and the roles community-based organizations play in supporting access. Recommendations are intended to help make sure that all health services are accessible to everyone, and move beyond a homogenizing category of "newcomers" into practical, meaningful strategies that attend to diverse and intersecting community needs.

Housing Instability and Evictions Linked to Elevated Intimate Partner and Workplace Violence Among Women Sex Workers in Vancouver, Canada: Findings of a Prospective, Community-Based Cohort, 2010-2019.

Objectives. To model the relationship of unstable housing and evictions with physical and sexual violence perpetrated against women sex workers in intimate and workplace settings. Methods. We used bivariate and multivariable logistic regression with generalized estimating equations to model the association of unstable housing exposure and evictions with intimate partner violence (IPV) and workplace violence among a community-based longitudinal cohort of cisgender and transgender women sex workers in Vancouver, Canada, from 2010 through 2019. Results. Of 946 women, 85.9% experienced unstable housing, 11.1% eviction, 26.2% IPV, and 31.8% workplace violence. In multivariable generalized estimating equation models, recent exposure to unstable housing (adjusted odds ratio [AOR] = 2.04; 95% confidence interval [CI] = 1.45, 2.87) and evictions (AOR = 2.45; 95% CI = 0.99, 6.07) were associated with IPV, and exposure to unstable housing was associated with workplace violence (AOR = 1.46; 95% CI = 1.06, 2.00). Conclusions. Women sex workers face a high burden of unstable housing and evictions, which are linked to increased odds of intimate partner and workplace violence. Increased access to safe, women-centered, and nondiscriminatory housing is urgently needed. (Am J Public Health. 2023;113(4):442-452. https://doi.org/10.2105/AJPH.2022.307207).

Migration and health research: past, present, and future.

Global migration continues to rise at unprecedented rates. Migrants are an extremely heterogeneous group and face diverse health needs related to infectious diseases, sexual and reproductive health, non-communicable diseases, and healthcare access across the whole lifespan. In this editorial, we set the context and invite contributions for a collection on 'Migration and health' at BMC Public Health.

"When you leave your country, this is what you're in for": experiences of structural, legal, and gender-based violence among asylum-seeking women at the Mexico-U.S. border.

BACKGROUND: Recent U.S. immigration policy has increasingly focused on asylum deterrence and has been used extensively to rapidly deport and deter asylum-seekers, leaving thousands of would-be asylum-seekers waiting indefinitely in Mexican border cities, a large and growing proportion of whom are pregnant and parenting women. In the border city of Tijuana, Mexico, these women are spending unprecedented durations waiting under unsafe humanitarian conditions to seek safety in the U.S, with rising concerns regarding increases in gender-based violence (GBV) among this population during the COVID-19 pandemic. Given existing gaps in evidence, we aimed to describe the lived experiences of GBV in the context of asylum deterrence policies among pregnant and parenting asylum-seeking women at the Mexico-U.S. border. METHODS: Within the community-based Maternal and Infant Health for Refugee & Asylum-Seeking Women (MIHRA) study, we conducted semi-structured qualitative interviews with 30 asylum-seeking women in Tijuana, Mexico between June and December 2022. Eligible women had been pregnant or postpartum since March 2020, were 18-49 years old, and migrated for the purposes of seeking asylum in the U.S. Drawing on conceptualizations of structural and legal violence, we conducted a thematic analysis of participants' experiences of GBV in the context of asylum deterrence policies and COVID-19. RESULTS: Pregnant and parenting asylum-seeking women routinely faced multiple forms of GBV perpetuated by asylum deterrence policies at all stages of migration (pre-migration, in transit, and in Tijuana). Indefinite wait times to cross the border and inadequate/unsafe shelter exacerbated further vulnerability to GBV. Repeated exposure to GBV contributed to poor mental health among women who reported feelings of fear, isolation, despair, shame, and anxiety. The lack of supports and legal recourse related to GBV in Tijuana highlighted the impact of asylum deterrence policies on this ongoing humanitarian crisis. CONCLUSION: Asylum deterrence policies undermine the health and safety of pregnant and parenting asylum-seeking women at the Mexico-U.S. border. There is an urgent need to end U.S. asylum deterrence policies and to provide respectful, appropriate, and adequately resourced humanitarian supports to pregnant and parenting asylum-seeking women in border cities, to reduce women's risk of GBV and trauma.

Migration and Mobility: Correlates of Recent HIV Testing Among Substance Using Female Sex Workers at the Mexico-Guatemala Border.

The goal of this paper is to determine the association between traveling to engage in sex work in another country and recent access to HIV testing among substance-using female sex workers (FSWs) in the Mexico-Guatemala border region. From 2012 to 2015, through modified time-location sampling and peer referral, 255 FSWs were recruited at Mexico's southern border. Participants completed questionnaires on sociodemographics, migration and mobility experiences, work environment factors, and substance use. A conceptual framework, as depicted by a directed acyclic graph (DAG), guided our analysis. Crude and adjusted logistic regression models were used to evaluate the relationships between mobility experiences and HIV testing in the past year. Overall HIV testing was low (41%); after considering relevant covariates (i.e., interaction with health services and organizations, and sex work characteristics) traveling to engage in sex work in another country was found to be positively associated with HIV testing in the past year. Future efforts need to consider voluntary and non-stigmatizing prevention HIV services and focus on reaching out to less mobile women.

RESUMEN: El objetivo de este artículo es determinar la asociación entre viajar a otro país para ejercer el comercio sexual y el acceso a una prueba reciente de VIH, en una población de mujeres trabajadoras sexuales en la frontera de México con Guatemala. Entre el 2012 y 2015, utilizando un muestreo por conveniencia y por referencia de pares, se invitó a 255 mujeres trabajadoras sexuales en la frontera sur de México a participar en este proyecto de investigación. Las participantes completaron una encuesta que comprendió preguntas sociodemográficas así como experiencias de migración y movilidad, características del trabajo sexual, y patrones de uso de sustancia. Utilizamos un marco conceptual que se ilustra en una Gráfica Acíclica Dirigida (DAG) el cual sirvió para guiar nuestro análisis. Realizamos análisis de regresión logística cruda y ajustada para evaluar la asociación entre experiencias de movilidad y haber recibido una prueba de VIH en el último año. En general, el porcentaje de haber recibido una prueba de VIH en el último año fue bajo (41%); después de considerar covariables relevantes; (ej., interacción con organizaciones y servicios de salud, características del trabajo sexual) encontramos que viajar a otro país para ejercer el comercio sexual está asociado con haber recibido una prueba de VIH en el último año. Es importante que, en el futuro, se concentren esfuerzos en servicios de prevención del VIH que sean voluntarios, no estigmatizantes, y que se enfoquen en mujeres trabajadoras sexuales menos móviles.

Sex work community participation in criminalized environments: a community-based cohort study of occupational health impacts in Vancouver, Canada: 2010-2019.

BACKGROUND: Sex work criminalization and occupational stigma pose barriers to sex workers' access to support services, including community participation - engagement with sex work specific community organizing at both formalized and grassroots capacities. In light of gaps in evidence regarding impacts of community participation on sex workers' occupational health in higher-income settings, we evaluated engagement in community participation and associations with occupational sexual health outcomes among sex workers in Vancouver, Canada. METHODS: Prospective data from a community-based cohort of 943 women sex workers in Vancouver, British Columbia (2010-2019). We used logistic regression with generalised estimating equations (GEE) to model correlates of community participation, and a confounder modeling approach to examine the association of community participation on sexually transmitted infection (STI) seropositivity. RESULTS: Among participants, 38.1% were Indigenous, 31.4% identified as women of colour (e.g., East Asian, Southeast Asian, Black) and 29.3% were im/migrants to Canada. Over a quarter (28.3%, n = 267) serviced in informal indoor spaces, while 38.0% (n = 358) serviced clients in outdoor/public and 31.4% (n = 296) in formal in-call spaces. 8.9% of participants reported sex work community participation at least once over the 9-year study. In multivariable GEE analysis, Indigenous (adjusted odds ratio(aOR) 1.71, 95% confidence interval (CI) 0.88-3.32) and trans women (aOR 4.69, 95%CI 2.43-9.06) had higher odds of community participation; women of colour had lower odds (aOR 0.18, 95%CI 0.06-0.57). In a multivariable GEE confounder model, community participation was independently associated with lower odds of STI seropositivity (aOR 0.66, 95% CI0.45-0.96). CONCLUSION: Sex workers who engaged in sex work community participation faced reduced odds of STI seropositivity. Building off reserach evaluating community interventions in low and middle income contexts, our study provides some of the first quantitative evidence on community participation among sex workers in Canada, and is the first to examine this in relation to sexual health outcomes. This research demonstrates the need to scale up community participation access for sex workers, via linguistically diverse community spaces, anti-stigma initiatives, and decriminalization to reduce barriers faced by racialized sex workers and support occupational health and rights for all sex workers.

Internet solicitation linked to enhanced occupational health and safety outcomes among sex workers in Metro Vancouver, Canada 2010-2019.

OBJECTIVES: Examine the independent association between online solicitation and sex workers' (SWs') occupational health and safety (OHS), particularly violence and work stress. METHODS: Data were drawn from a cohort of women SWs (N=942, 2010-2019) in Vancouver, Canada. Analyses used descriptive statistics and bivariate and multivariable logistic and linear regression using generalised estimating equations (GEE); explanatory and confounder modelling approaches were used. RESULTS: 33.9% (n=319) of participants solicited online and 14.1% (n=133) primarily solicited online in the last 6 months in at least one study visit. In multivariable GEE analysis, factors associated with primarily soliciting online included younger age (adjusted OR (AOR) 0.95 per year older, 95% CI 0.93 to 0.97), sexual minority status (AOR 2.57, 95% CI 1.61 to 4.10), gender minority status (AOR 3.09, 95% CI 1.80 to 5.28), higher education (AOR 2.13, 95% CI 1.34 to 3.40), higher sex work income (AOR 1.03 per $100 weekly, 95% CI 1.01 to 1.06), being an im/migrant to Canada (AOR 2.40, 95% CI 1.26 to 4.58) and primarily servicing in informal indoor workspaces (AOR 3.47, 95% CI 2.32 to 5.20). In separate GEE confounder models, primarily soliciting online significantly (1) reduced odds of physical/sexual workplace violence (AOR 0.64, 95% CI 0.39 to 1.06) and (2) reduced work stress (ß coefficient -0.93, 95% CI -1.59 to -0.26). DISCUSSION/CONCLUSIONS: Younger workers, gender/sexual minorities, im/migrants and those in informal indoor spaces had higher odds of soliciting online. Confounder models indicate access to online solicitation methods may support enhanced OHS. Decriminalisation of sex work-including advertising via online platforms-remains necessary to support SWs' OHS.

Seeing pre-screened, regular clients associated with lower odds of workplace sexual violence and condom refusal amidst sex work criminalization: findings of a community-based cohort of sex workers in Metro Vancouver, Canada (2010-2019).

BACKGROUND: Research that accurately represents how characteristics of sex work clients relate to sex workers' labour conditions is crucial for informing evidence-based legislation which upholds sex workers' human rights. As little quantitative research has examined how seeing regulars (repeat clients) impacts sex workers' occupational safety, particularly under 'end-demand' criminalization in Canada, our study aimed to explore how seeing mostly regulars shapes workplace sexual violence and client condom refusal. METHODS: We drew on longitudinal data from a community-based open cohort of 900+ sex workers in Vancouver, recruited via time-location sampling during day and late-night outreach to indoor, outdoor, and online solicitation spaces. We used logistic regression analyses and multivariable GEE confounder models to 1) describe correlates of seeing mostly pre-screened, regular clients, 2) identify associations between seeing mostly regulars and odds of experiencing occupational outcomes of workplace sexual violence and client condom refusal, and 3) examine the interaction between seeing mostly regulars and work environment on workplace sexual violence and client condom refusal. RESULTS: Participants' median age was 35, and 55.6% had completed high school. Over the 9-year study (n=925), 20.9% (193) experienced 282 events of workplace sexual violence and 40.2% (372) faced 702 events of client condom refusal. In multivariable GEE confounder models, seeing mostly regulars was associated with reduced odds of sexual violence (AOR 0.73, 95%CI 0.53-1.02, p=0.067) and client condom refusal (AOR 0.70, 95%CI 0.57-0.86). In multivariable GEE confounder models examining the additive interaction between seeing mostly regulars and work environment, participants who saw mostly regulars and primarily worked in outdoor or informal indoor venues faced significantly lower odds of experiencing workplace sexual violence (AOR 0.69, 95%CI 0.49-0.95) and client condom refusal (AOR 0.64, 95%CI 0.52 -0.80) relative to those who worked in the same venues and did not see mostly regulars. CONCLUSION: Our findings highlight protective effects of seeing pre-screened regulars within a criminalized setting. Removal of 'end-demand' client criminalization is needed to enable sex workers to effectively screen clients, support HIV/STI prevention, and advance sex workers' human rights.

Sharpening our public health lens: advancing im/migrant health equity during COVID-19 and beyond.

BACKGROUND: Differential impacts of the COVID-19 pandemic have brought deeply rooted inequities to the forefront, where increasing evidence has shown that racialized immigrant and migrant (im/migrant) populations face a disproportionate burden of COVID-19. Im/migrant communities may be worst affected by lockdowns and restrictive measures, face less opportunity to physically distance or stay home sick within 'essential' jobs, and experience severe barriers to healthcare. Insufficient attention to experiences of racialized im/migrants in current pandemic responses globally highlights an urgent need to more fulsomely address unmet health needs through an anti-racist, equity-oriented lens. This commentary aims to highlight the need for public health and clinical training, research, and policy to thoughtfully prioritize im/migrant health equity during and beyond the COVID-19 pandemic. MAIN TEXT: Global pandemic responses have neglected im/migrants by continuing to ignore or insufficiently address inequities, exacerbating COVID transmission, xenophobia, and occupational injustice. Deaths, illness, stress, and other negative outcomes of the overlapping epidemics of COVID-19 and structural racism disproportionately borne by racialized im/migrants suggest the urgent need for action. As evidence mounts about how im/migrants have been left behind in times of crises, we need enhanced focus on health equity within COVID-19 research and interventions, including research that examines and pursues structural interventions necessary to mitigate these impacts, and that identifies patterns and harms of xenophobic policy, structural racism, and white supremacy in shaping im/migrant health outcomes. We must also strengthen anti-racist and equity-oriented curriculum within health education, and ensure sufficient attention to the needs of im/migrant communities within public health, clinical, and research training. CONCLUSION: The COVID-19 pandemic has exacerbated and rendered more visible the deeply rooted health and social inequities faced by racialized im/migrants across diverse settings. We argue for a greater emphasis on equity-focused and anti-racist im/migrant health research, interventions, and training. Policymakers and practitioners must ensure that healthcare policies and practices do not exacerbate inequities, and instead meaningfully address unmet needs of communities, including racialized im/migrants. Ethical and respectful community engagement, commitment and collaboration with global, national, and local communities, policymakers, academics, and educators, as well as accountability across sectors, is critical.

Harms of third party criminalisation under end-demand legislation: undermining sex workers' safety and rights.

After Canada's laws criminalising sex work were struck down by the Supreme Court for violating sex workers' rights and new end-demand legislation was passed in 2014. These new laws however continue to criminalise sex work third parties (i.e. venue owners/managers) who gain material benefits, despite evidence that managed in-call venues can provide important protections for sex workers. As part of a longstanding community-based study in Vancouver, this analysis drew on 25 in-depth interviews with third parties who provide services for indoor sex workers. We explored how end-demand third party criminalisation shapes indoor sex workers' working conditions, health and safety. We found that most third parties were women and current/former sex workers, problematising assumptions of third parties as exploitative male "pimps". Third parties provided client screening, security and sexual health resources for sex workers, yet end-demand laws restricted condom availability and access to police protections in case of violence, thereby undermining sex workers' health and safety. Our findings highlight that third party criminalisation under end-demand legislation reproduces the unsafe working conditions under the previous laws deemed unconstitutional by Canada's highest court. Legislative reforms to decriminalise all aspects of the sex industry, including sex workers' right to work with third parties, are urgently needed.

Third Parties (Venue Owners, Managers, Security, etc.) and Access to Occupational Health and Safety Among Sex Workers in a Canadian Setting: 2010-2016.

OBJECTIVE: To determine the impact of engagement with third parties (i.e., managers, receptionists, or owners of in-call venues; advertisers; security; spotters; and others) on sex workers' occupational health access. METHODS: We drew longitudinal data from An Evaluation of Sex Workers' Health Access, a community-based cohort of more than 900 women sex workers. We used multivariable logistic regression and generalized estimating equations to (1) examine factors correlated with accessing third-party administrative or security services and (2) evaluate the impact of third-party services on access to mobile condom distribution and sex worker and community-led services (2010-2016). Finally, we evaluated changes in accessing third-party services pre-post end-demand criminalization (2010-2017). RESULTS: Im/migrant sex workers (persons with any type of legal status who were born in another country; adjusted odds ratio [AOR] = 2.32; 95% confidence interval [CI] = 1.35, 3.98) had higher odds of accessing third-party services. In confounder models, third-party services were independently correlated with increased access to mobile condom distribution (AOR = 1.84; 95% CI = 1.47, 2.31) and sex worker and community-led services (AOR = 1.61; 95% CI = 1.15, 2.24). End-demand criminalization was linked to a decrease in access to third-party services (AOR = 0.79; 95% CI = 0.63, 0.99). CONCLUSIONS: This research suggests that access to administrative and security services from third parties increases sex workers' occupational health and safety. Policy reforms to ensure sex workers' labor rights, including access to hiring third parties, are recommended.

Preventing sexually transmitted and blood borne infections (STBBIs) among sex workers: a critical review of the evidence on determinants and interventions in high-income countries.

BACKGROUND: Across diverse regions globally, sex workers continue to face a disproportionate burden of HIV and other sexually transmitted and blood borne infections (STBBIs). Evidence suggests that behavioural and biomedical interventions are only moderately successful in reducing STBBIs at the population level, leading to calls for increased structural and community-led interventions. Given that structural approaches to mitigating STBBI risk beyond HIV among sex workers in high-income settings remain poorly understood, this critical review aimed to provide a comprehensive synthesis of the global research and literature on determinants of HIV and other STBBIs and promising intervention practices for sex workers of all genders in high-income countries. METHODS: We searched for publications over the last decade (January 2005-March 2016) among sex workers (cis women, cis men, and trans individuals). Data obtained from quantitative peer-reviewed studies were triangulated with publicly available reports and qualitative/ethnographic research where quantitative evidence was limited. RESULTS: Research demonstrates consistent evidence of the direct and indirect impacts of structural factors (e.g., violence, stigma, criminalization, poor working conditions) on increasing risk for STBBIs among sex workers, further compounded by individual and interpersonal factors (e.g., mental health, substance use, unprotected sex). Sub-optimal access to health and STBBI prevention services remains concerning. Full decriminalization of sex work has been shown to have the largest potential to avert new infections in sex work, through reducing workplace violence and increasing access to safer workspaces. Promising practices and strategies that should be scaled-up and evaluated to prevent STBBIs are highlighted. CONCLUSIONS: The high burden of STBBIs among sex workers across high-income settings is of major concern. This review uniquely contributes to our understanding of multilevel factors that potentiate and mitigate STBBI risk for sex workers of all genders. Research suggests that multipronged structural and community-led approaches are paramount to addressing STBBI burden, and are necessary to realizing health and human rights for sex workers. Given the heterogeneity of sex worker populations, and distinct vulnerabilities faced by cis men and trans sex workers, further research utilizing mixed-methods should be implemented to delineate the intersections of risk and ameliorate critical health inequalities.

Influence of indoor work environments on health, safety, and human rights among migrant sex workers at the Guatemala-Mexico Border: a call for occupational health and safety interventions.

BACKGROUND: Migrant women are over-represented in the sex industry, and migrant sex workers experience disproportionate health inequities, including those related to health access, HIV and sexually transmitted infections (STIs), and violence. Despite calls for occupational sex work interventions situated in labour rights frameworks, there remains a paucity of evidence pertaining to migrant sex workers' needs and realities, particularly within Mexico and Central America. This study investigated migrant sex workers' narratives regarding the ways in which structural features of work environments shape vulnerability and agency related to HIV/STI prevention and violence at the Guatemala-Mexico border. METHODS: Drawing on theoretical perspectives on risk environments and structural determinants of HIV in sex work, we analyzed in-depth interviews, focus groups, and ethnographic fieldwork conducted with 39 migrant sex workers in indoor work environments between 2012 and 2015 in Tecún Umán, Guatemala. RESULTS: Participant narratives revealed the following intersecting themes to be most closely linked to safety and agency to engage in HIV/STI prevention: physical features of indoor work environments (e.g., physical layout of venue, proximity to peers and third parties); social norms and practices for alcohol use within the workplace; the existence and nature of management practices and policies on health and safety practices; and economic influences relating to control over earnings and clients. Across work environments, health and safety were greatly shaped by human rights concerns stemming from workplace interactions with police, immigration authorities, and health authorities. CONCLUSIONS: Physical isolation, establishment norms promoting alcohol use, restricted economic agency, and human rights violations related to sex work policies and immigration enforcement were found to exacerbate risks. However, some establishment policies and practices promoted 'enabling environments' for health and safety, supporting HIV/STI prevention, economic agency, and protection from violence and exploitation; these practices and policies were especially crucial for recent migrants. Policy reforms and structural workplace interventions tailored to migrant sex workers' needs are recommended to promote improved working conditions and migrant sex workers' health, safety, and human rights.

Interpersonal and structural contexts of intimate partner violence among female sex workers in conflict-affected northern Uganda.

Intimate partner violence (IPV) is the most prevalent form of violence against women, yet remains under-researched among sex workers in sub-Saharan Africa. We explored the interpersonal and structural determinants of recent IPV among female sex workers in northern Uganda. This analysis drew on data from a community-based cross-sectional study (conducted May 2011-January 2012), involving 379 female sex workers in Gulu, northern Uganda. Using logistic regression and multivariable modeling, we examined the correlates of recent male-perpetrated physical or sexual IPV. Of 379 women with noncommercial partners, 59 percent reported having experienced recent moderate/severe physical or sexual IPV. Reporting recent client violence (adjusted odds ratio (AOR): 3.67; 95 percent confidence interval [CI]: 2.31-5.83), doing what their partner wanted (AOR: 2.46; 95 percent CI: 1.46-4.13), and forced sexual debut (AOR: 1.92; 95 percent CI: 1.20-3.05) were independently associated with moderate/severe IPV; recent police arrest and/or incarceration were/was marginally significantly associated with IPV (AOR: 2.25; 95 percent CI: 0.86-5.88, p = 0.097). Greater odds of IPV among sex workers were associated with recent workplace violence, forced sexual debut, and gendered power dynamics favoring male partner control. Programs and policies promoting the safety and health of marginalized women and addressing gender dynamics and violence are needed.

Food Insecurity Increases HIV Risk Among Young Sex Workers in Metro Vancouver, Canada.

This research aimed to determine the effect of food insecurity on sexual HIV risk with clients among youth sex workers (YSWs) <30 years in Metro Vancouver, Canada. Data were drawn from a prospective community cohort of sex workers (2010-2013). We examined the independent relationship between YSWs' food insecurity and being pressured into sex without a condom by clients ("client condom refusal"). Of 220 YSWs, 34.5 % (n = 76) reported client condom refusal over the 3.5-year study period and 76.4 % (n = 168) reported any food insecurity. Adjusting for other HIV risk pathways, food insecurity retained an independent effect on client condom refusal (AOR 2.08, 95 % CI 1.23-3.51), suggesting that food insecurity is significantly associated with HIV risk among YSWs. This study indicates a critical relationship between food insecurity and HIV risk, and demonstrates YSWs' particular vulnerability. Public policies for food assistance as a harm reduction measure may be key to addressing this disparity.
