Homelessness among a cohort of women in street-based sex work: the need for safer environment interventions

Impact of a Community Empowerment Intervention on Sexually Transmitted Infections Among Female Sex Workers in Baltimore, Maryland

BACKGROUND

Female sex workers ( FSWs) are vulnerable to a number of health issues, but often delay seeking health care due to structural barriers. Multiservice drop-in centers have been shown to increase FSW access to health services globally, but their impact on FSW in the United States is lacking. This study seeks to evaluate the effect of a community-level empowerment intervention (the multiservice drop-in SPARC center) on cumulative sexually transmitted infections (STIs) among FSW in a city in the United States.

METHODS

Between September 2017 and January 2019, 385 FSWs were recruited in Baltimore. Participants from areas served by SPARC were recruited to the intervention; other areas of Baltimore were the control. Follow-up occurred at 6, 12, and 18 months. The primary outcome is cumulative STI (ie, positive gonorrhea or chlamydia test at any follow-up). We tested effect modification by condomless sex with paying clients reported at baseline. Logistic regressions with propensity score weighting were used to estimate intervention effect, accounting for loss to follow-up, with bootstrap confidence intervals.

RESULTS

Participants completed 713 follow-up study visits (73%, 70%, 64% retention at 6, 12, and 18 months, respectively). Baseline STI prevalence was 28% and cumulative STI prevalence across follow-ups was 26%; these both did not differ between control and intervention communities in bivariate analyses. After adjusting for covariates, FSW in the intervention had a borderline-significant decrease in odds of cumulative STI compared with control (odds ratio, 0.61, P = 0.09 ) . There was evidence of effect modification by baseline condomless sex, such that FSW in the intervention who reported condomless sex had lower odds of cumulative STI compared with FSW in the control community who also reported baseline condomless sex (odds ratio, 0.29; P = 0.04).

CONCLUSIONS

Results demonstrate the value of a low-barrier, multiservice model on reducing STIs among the highest-risk FSW.Clinical Trial Number: NCT04413591.

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).

Understanding the longitudinal relationship between substance use and violent victimization among street-based women who exchange sex in Baltimore, Maryland

BACKGROUND

Women who exchange sex (WES) experience extensive interpersonal violence from multiple perpetrators. Violence towards WES contributes to poor mental and behavioral health outcomes, including high rates of drug use. However, it is difficult to disentangle the temporal relationship between drug use and violence among WES.

METHODS

We used data from 251 WES, who completed baseline and 6-month follow up surveys. WES reported baseline sociodemographic characteristics, including homelessness and hunger. Participants reported their drug use by type and violent experiences by perpetrator at each time point. We conducted a path analysis examining the associations between drug use and violent victimization over time.

RESULTS

Participants were on average 37.8 years old, non-Hispanic White (57.4%) and experiencing high levels of structural vulnerability (59.4% homelessness; 58.6% weekly hunger). Drug use and violence were significantly correlated within each time point. Prospectively, baseline violent victimization was significantly associated with drug use (ß (SE) = 0.13 (0.06)) and violence (ß (SE) = 0.47 (0.05)) at follow up. Baseline drug use was associated with drug use at follow up (ß (SE) = 0.45 (0.05)) but was not significantly associated with violence at follow up (ß (SE) = 0.10 (0.06)).

CONCLUSIONS

Violence and drug use are closely linked in this population; and violence appears to facilitate sustained drug use. Interventions to address the dual epidemics of violence and substance use in this population should address underlying trauma as well as socio-structural drivers of violence as well as tailored harm reduction services for this population.

Family matters in Canada: understanding and addressing family homelessness in Ontario

Background

Homelessness is becoming an international public health issue in most developed countries, including Canada. Homelessness is regarded as both political and socioeconomic problems warranting broad and consistent result-oriented approaches.

Methods

This paper represents the qualitative findings of a project that explored risk factors associated with family homelessness and strategies that could mitigate and prevent homelessness among families using a focused ethnographic study guided by the principles of participatory action research (PAR). The sample includes 36 family members residing at a family shelter who participated in focus groups over two years (between April 2016 and December 2017). Most of the participants were single-parent women.

Results

The analysis yielded five major themes including, life challenges, lack of understanding of the system, existing power differentials, escaping from hardship, and a theme of proposed solutions for reducing family homelessness in the community.

Conclusion

The findings illustrated the complex nature of family homelessness in Ontario; that the interaction of multiple systems can put families at risk of homelessness. Findings from this study underscore the need for urgent housing protocols aimed at educating homeless families on how to navigate and understand the system, enhance their conflict resolution skills, and develop strategies beyond relocation to help them to cope with difficulties with housing.

Patterns of Sex Work Client Solicitation Settings and Associations with HIV/STI Risk Among a Cohort of Female Sex Workers in Baltimore, Maryland

Female sex workers' (FSWs) risk for HIV/STIs is influenced by their work environments. While previous research has characterized vulnerability in a single workplace, many FSWs solicit clients from multiple settings. Using latent class analysis (LCA), we examined client solicitation patterns and associated HIV/STI-related behaviors (consistent condom use with clients, asking clients about HIV/STIs, and past 6-month HIV/STI testing) among 385 FSWs in Baltimore, Maryland. The LCA yielded a three-class solution: predominantly street (61.2%), mixed street/venue (23.7%), and multisource (street, venue, and online) (15.1%). Consistent condom use differed significantly (p < 0.01) by class, with the mixed street/venue having the lowest (40.6%) rate and the multisource having the highest (70.6%). Classes differed on HIV/STI testing (p < 0.01), with the predominantly street class having the lowest testing rate (56.2%) and multisource with the highest (85.7%). These findings underscore the importance of considering how solicitation patterns are linked to HIV/STI susceptibility of FSWs and adapting interventions accordingly.

Women's multiple uses of an overdose prevention technology to mitigate risks and harms within a supportive housing environment: a qualitative study

Background

North America is amidst an opioid overdose epidemic. In many settings, particularly Canada, the majority of overdose deaths occur indoors and impact structurally vulnerable people who use drugs alone, making targeted housing-based interventions a priority. Mobile applications have been developed that allow individuals to solicit help to prevent overdose death. We examine the experiences of women residents utilizing an overdose response button technology within a supportive housing environment.

Methods

In October 2019, we conducted semi-structured qualitative interviews with 14 residents of a women-only supportive housing building in an urban setting where the overdose response button technology was installed. Data was analyzed thematically and framed by theories of structural vulnerability.

Results

While participants described the utility and disadvantages of the technology for overdose response, most participants, unexpectedly described alternate adoptions of the technology. Participants used the technology for other emergency situations (e.g., gender-based violence), rather than its intended purpose of overdose response.

Conclusions

Our findings highlight the limitations of current technologies while also demonstrating the clear need for housing-based emergency response interventions that address not just overdose risk but also gender-based violence. These need to be implemented alongside larger strategies to address structural vulnerabilities and provide greater agency to marginalized women who use drugs.

Pathways through homelessness among women in Addis Ababa, Ethiopia: A qualitative study

Background

There has been a paradigm shift in understanding homelessness. The shift is from the belief that homelessness results from lack of secure housing towards the view which explains homelessness in terms of the complex interactions of factors which determine the pathways into and out of homelessness. The evidence base for women’s homelessness is less robust than men’s homelessness. The effect of gender and its relationship with homelessness has been neglected. Addis Ababa, the capital city of Ethiopia, is estimated to be home for around 50,000 homeless people. This study aims to explore pathways through homelessness in women who were sheltered in a facility for the homeless in Addis Ababa.

Methods

In-depth interviews were conducted in 2019 with 14 women who were ‘roofless’, and were gathered for support in a temporary shelter in Addis Ababa, Ethiopia. The shelter was one of the eight such facilities established in Addis Ababa few months earlier than the study. For data analysis the QDA Miner 5.0.30 software was used and data was analyzed using thematic analysis approach.

Results

The analysis revealed that determinant factors for pathways into homelessness among women occurred on the background of predisposing factors, such as poverty, being raised by caregivers other than biological parents, child marriage, unstable employment history. On top of the predisposing factors listed above the occurrence of precipitating factors such as problems with marriage, migration, death of parents, deception, became the immediate cause of homelessness. Despite mentions of positive experiences of homelessness such as mutual support and good social life within network of homeless people, the net effect of the interaction between negative and positive experiences of the homeless life, together with the effectiveness of coping strategies by the participants resulted in the participants’ decision of whether homelessness is tolerable. Finally, the presence of perpetuating factors such as lack of affordable house, feeling of shame to go back home, and unfavorable situation at home discouraged participants from exiting the homeless situation.

Conclusion

From the findings of the study we conclude that the predisposing factors and the precipitating factors resulted in the occurrence of onset of homelessness among the participants. Once homeless, the experiences of life as homeless, and the availability of the means to exit from it determined whether the participants would stay homeless or exit from it.

Social and structural determinants of health associated with drug use patterns among female sex workers in Iran: A latent class analysis

BACKGROUND

Female sex workers (FSWs) experience adversities regarding social determinants of health (SDH) and behavioural factors including illicit drug use. This study aimed to assess the clustered impact of SDH on illicit drug use among FSWs in Iran.

METHODS

We surveyed 1,347 FSWs in 13 major cities in 2015. Latent class analysis was conducted to identify distinct classes of five measured SDH including low education, unemployment, unstable housing, last-year incarceration and sexual violence. We examined the association of these classes with five illicit drug use patterns using multivariable generalized linear model with Poisson family and log link, and reported adjusted prevalence ratios (aPR) and their 95% confidence intervals (CI).

RESULTS

We identified five SDH classes: Class 1: no SDH adversities; Class 2: mainly unemployment; Class 3: low education and unemployment; Class 4: sexual violence and unemployment; and Class 5: multiple SDH adversities. The prevalence of last-month drug use ranged from 7.0% in Class 1 to 53.3% in Class 5. Compared to FSWs in Class 1, those in Class 2 (aPR: 2.47, 95% CI: 1.15, 5.27), Class 3 (aPR: 3.69, 95% CI: 1.62, 8.36), Class 4 (aPR: 4.49, 95% CI: 1.71, 11.78) and Class 5 (aPR: 6.35, 95% CI: 2.42, 16.69) were more likely to report last-month drug use. The same patterns were observed for specific drugs of opium use, crystal methamphetamine use, and heroin-crack use, as well as poly-drug use.

CONCLUSION

Socio-structural determinants are clustered together and elevate the likelihood of illicit drug use among FSWs. Our findings highlighted the significance of assessing and addressing such key determinants of health in drug use harm reduction programs targeting FSWs.

Entry to Sex Trade and Long-Term Vulnerabilities of Female Sex Workers Who Enter the Sex Trade Before the Age of Eighteen

Female sex workers are a structurally vulnerable population, including critical insecurity such as having access to food and shelter. This risk may be heightened among individuals who enter sex work as minors. However, the reasons for entering sex work as a minor and the long-term structural risk implications are poorly understood. Here, we investigated the reasons for and long-term impact of trading sex before the age of eighteen on women's structural vulnerability among a cohort of 250 cisgender women involved in street-based sex work in Baltimore City, Maryland, USA. We used logistic regression to explore the role of age of entry on two structural vulnerability outcomes of interest (homelessness and recent food insecurity in the past 3 months). Overall, 73% of women entered the sex trade to get drugs, 36% of women entered to get basic necessities such as food or housing, and 17% of women entered to support their children or family. Of significance, 21% of those aged < 18 years at entry reported being either coerced, threatened, pressured, misled, tricked, or physically forced into trading sex compared to 5% in those who entered at an older age group (p value < 0.001). In adjusted analysis, women who first trade sex before the age of 18 had 4.54 increased odds of experiencing recent homelessness (95% CI 1.92-10.70) and had 3.14 times increased odds of experiencing recent food insecurity (95% CI 1.42-6.94). Those who entered as minors were also more likely to be HIV positive (11.3% vs 3.6%, p value = 0.02). This study highlights that those who trade sex at a younger age experience an ongoing cumulative vulnerability in comparison to those entering over the age of 18. These findings call for additional research into a more detailed understanding of young women's entry into the sex trade and trajectory. A focus on the importance of policy changes and structural interventions that directly alleviate young people's socio-economic disadvantage is needed.

"We don't got that kind of time, man. We're trying to get high!": Exploring potential use of drug checking technologies among structurally vulnerable people who use drugs

BACKGROUND

Novel public health interventions are being considered to address the opioid overdose epidemic, including drug checking technologies. We examined the willingness to use various drug checking technologies among structurally-vulnerable people who use drugs (PWUD).

METHODS

We conducted one-to-one qualitative semi-structured interviews with 20 PWUD in Vancouver, Canada's Downtown Eastside. Participants were purposively recruited from ongoing cohort studies of PWUD.

RESULTS

Overall willingness to use drug checking technologies was low among participants. A range of factors undermined potential use of various drug checking technologies including: having to give up a drug sample; time dedication; discrepancies regarding measurements and accuracy; recourse following positive fentanyl results; ambivalence to overdose risk; and availability and accessibility of drug checking technologies.

CONCLUSIONS

Participants discussed numerous factors that undermined potential willingness to use drug checking technologies. These factors underscore the structural vulnerabilities experienced by PWUD and how they may constrain uptake of drug checking technologies. Future drug checking programming should consider these influencing factors prior to the implementation of drug checking technologies to ensure that drug checking interventions are appropriate and meeting the needs of target populations.

Overlapping intimate partner violence and sex trading among high-risk women: Implications for practice

Despite research indicating higher than average rates of intimate partner violence (IPV) across groups of vulnerable women, less is known about the prevalence and types of IPV experienced by women who trade sex for money, drugs, shelter or food, a high risk group for poor health and psychosocial outcomes. Using a cross-sectional design and multivariate logistic regression analyses, this study examined the relationship between IPV and sex trading in a convenience sample of 346 HIV-negative, drug-involved women in relationships, recruited during 2005-2010 in New York City. About 41% and 36% of participants reported lifetime and recent IPV, respectively, by their main partner, with significant differences by recent engagement in sex trading (p < 0.01). Results of multivariate analyses indicated that sex trading was associated with recent severe physical or sexual IPV (OR = 3.07, p < 0.01) and that depression, having ever been married, child sexual abuse, and income were associated with IPV (p < 0.05). Women who reported childhood sexual abuse and recent sex trading had a 7.37 higher odds (p < 0.01) for reporting severe physical or sexual IPV compared to those who reported neither. Findings highlight the need to expand screening and interventions among women who trade sex.

Structural factors associated with methamphetamine smoking among female sex workers in Tijuana, Mexico

INTRODUCTION AND AIMS

Smoking methamphetamine is associated with increased risk of HIV among female sex workers (FSW). The structural context of substance use is an important shaper of individual behaviour; however, structural determinants of methamphetamine use among FSWs are largely unknown. We identified individual, structural and neighbourhood factors associated with smoking methamphetamine among FSWs in the border city of Tijuana, Baja California, Mexico.

DESIGN AND METHODS

A prospective cohort of 301 FSWs sampled from indoor and outdoor sex work venues throughout Tijuana participated in quantitative surveys on behaviours and mapping of home and work neighbourhoods across three visits. Multinomial logistic regression using generalised estimating equations identified individual, structural and neighbourhood variables associated with smoking methamphetamine.

RESULTS

Methamphetamine use, particularly smoking, was highly prevalent among FSWs. Over half (61%) of FSWs had ever used methamphetamine in their lifetime and at baseline, 38% currently smoked methamphetamine. Smoking methamphetamine daily was associated with living in the red light district [adjusted odds ratio (AOR) = 2.72, 95% confidence interval (CI) = 1.23-6.02] and with perceived homelessness, but only among women in a good financial situation (AOR = 4.08, 95% CI = 1.58-10.50). Smoking methamphetamine less than daily was associated with older age (AOR = 1.06, 95% CI = 1.02-1.10).

DISCUSSION AND CONCLUSIONS

Our findings point to the important dynamic between the residential environment and more severe methamphetamine use. FSWs may prioritise the purchase of methamphetamine over stable housing if they have the financial means. Given the high prevalence of smoking methamphetamine among FSWs in Tijuana, drug treatment options, especially for women living in the red light district, are needed.

Prevalence of HIV Among U.S. Female Sex Workers: Systematic Review and Meta-analysis

Although female sex workers are known to be vulnerable to HIV infection, little is known about the epidemiology of HIV infection among this high-risk population in the United States. We systematically identified and critically assessed published studies reporting HIV prevalence among female sex workers in the United States. We searched for and included original English-language articles reporting data on the prevalence of HIV as determined by testing at least 50 females who exchanged sexual practices for money or drugs. We did not apply any restrictions on date of publication. We included 14 studies from 1987 to 2013 that reported HIV prevalence for a total of 3975 adult female sex workers. Only two of the 14 studies were conducted in the last 10 years. The pooled estimate of HIV prevalence was 17.3 % (95 % CI 13.5-21.9 %); however, the prevalence of HIV across individual studies varied considerably (ranging from 0.3 to 32 %) and statistical heterogeneity was substantial (I(2) = 0.89, Q = 123; p < 0.001). Although the variance across the 14 studies was high, prevalence was generally high (10 % or greater in 11 of the 14 included studies). Very few studies have documented the prevalence of HIV among female sex workers in the United States; however, the available evidence does suggest that HIV prevalence among this vulnerable population is high.

Barriers to Viral Suppression Among Female Sex Workers: Role of Structural and Intimate Partner Dynamics

OBJECTIVE

Despite global evidence that sex workers (SWs) are disproportionately impacted by HIV, data on HIV treatment outcomes among SWs living with HIV remains sparse. This study examined the correlates of undetectable plasma viral load (pVL) among street- and off-street SWs living with HIV and on antiretroviral therapy (ART) in Metro Vancouver, Canada.

METHODS

Analyses drew on data (2010-2014) from a longitudinal cohort of SWs (An Evaluation of Sex Workers Health Access) and confidential linkages with the Drug Treatment Program (DTP) data on ART dispensation and outcomes. Bivariate and multivariable generalized linear mixed-effects models were used to identify longitudinal correlates of undetectable pVL (<50 copies/mL).

RESULTS

Of the 72 SWs living with HIV who had ever used ART, 38.9% had an undetectable pVL at baseline. Although 84.7% had undetectable pVL at least once over the study period, 18.1% exhibited sustained undetectable pVL. In multivariable generalized linear mixed-effects model analyses, ≥95% pharmacy refill adherence (adjusted odds ratio (AOR) = 4.21; 95% confidence interval (CI) 2.16 to 8.19) and length of time since diagnosis (AOR = 1.06; 95% CI: 1.00 to 1.13) were positively correlated with undetectable pVL. Having an intimate male partner (AOR = 0.35; 95% CI: 0.16 to 0.78) and being homelessness were negatively correlated with undetectable pVL (AOR = 0.22; 95% CI: 0.10 to 0.47).

DISCUSSION/CONCLUSIONS

There is a need to more closely consider the social and structural contexts that shape SWs' experiences on ART and impact treatment outcomes, including the gendered power dynamics within intimate partnerships. Future research on HIV care among SWs is urgently needed, alongside structural and community-led interventions to support SWs' access to and retention in care.

The impact of violence on sex risk and drug use behaviors among women engaged in sex work in Phnom Penh, Cambodia

BACKGROUND

Violence, substance use, and HIV disproportionately impact female entertainment and sex workers (FESW), but causal pathways remain unclear.

METHODS

We examined data from an observational cohort of FESW age 15-29 in Phnom Penh, Cambodia for associations between violence exposure and sexual risk and drug use. Validated measures of physical and sexual violence were assessed at baseline. Self-reported outcomes measured quarterly over the next 12-months included past month sexual partners, consistent condom use by partner type, sex while high, and amphetamine type stimulant (ATS) use. Biomarkers measured quarterly included prostate specific antigen (PSA) and urine toxicology. Generalized estimating equations were fit adjusting for age, education, marital status and sex work venue.

RESULTS

Of 220 women, 48% reported physical or sexual violence in the preceding 12-months. Physical violence was associated with increased number of sex partners (adjusted incidence rate ratio [aIRR] 1.33; 95% CI: 1.04-1.71), greater odds of sex while high (adjusted odds ratio [aOR] 2.42; 95% CI: 1.10-5.33), increased days of ATS use (aIRR 2.74; 95% CI: 1.29-5.84) and increased odds of an ATS+ urine screen (aOR 2.80, 95%CI: 1.38-5.66). Sexual violence predicted decreased odds of consistent condom use with non-paying partners (aOR 0.24; 95% CI: 0.10-0.59) and greater odds of a PSA+ vaginal swab (aOR 1.83; 95% CI: 1.13-2.93).

CONCLUSIONS

Physical and sexual violence are prevalent among Cambodian FESW and associated with subsequent sexual risk and drug use behaviors. Clinical research examining interventions targeting structural and interpersonal factors impacting violence is needed to optimize HIV/AIDS prevention among FESW.

The Relationship Between Non-Medical Use of Prescription Opioids and Sex Work Among Adults in Residential Substance Use Treatment

High rates of substance use (e.g., alcohol, cocaine, heroin) have been documented among individuals who engage in sex work (SW), and adults seeking substance use disorder (SUD) treatment frequently report prior engagement in SW. Non-medical use of prescription opioids (NMUPO) has increased over the last decade, but little is known about the relationship between NMUPO with sex exchange. The purpose of this study was to describe the prevalence of recent SW among patients at a large residential SUD treatment center and examine the association between NMUPO and SW. Approximately 14% of 588 adults reported involvement in SW in the month prior to treatment. NMUPO was more common among those with a history of SW (95% of sex workers vs. 74% of non-sex-workers), and this association remained statistically significant after controlling for demographic factors, other substance use and psychiatric symptom severity (odds ratio=3.38). SW is relatively common among patients in residential SUD treatment, and is associated with greater psychiatric severity and more extensive substance use, including alarming rates of NMUPO. Addiction treatment for individuals involved in SW may benefit from the addition of content related to NMUPO.

Social and Structural Factors Shaping High Rates of Incarceration among Sex Workers in a Canadian Setting

In light of the emphasis on enforcement-based approaches towards sex work, and the well-known negative impacts of these approaches on women's health, safety and well-being, we conducted a study to investigate the prevalence and correlates of recent incarceration among a cohort of women sex workers in Vancouver, Canada. Data were obtained from an open prospective community cohort of female and transgender women sex workers, known as An Evaluation of Sex Workers' Health Access (AESHA). Bivariate and multivariable logistic regression analyses, using generalized estimating equations (GEE), were used to model the effect of social and structural factors on the likelihood of incarceration over the 44-month follow-up period (January 2010-August 2013). Among 720 sex workers, 62.5 % (n = 450) reported being incarcerated in their lifetime and 23.9 % (n = 172) being incarcerated at least once during the study period. Of the 172 participants, about one third (36.6 %) reported multiple episodes of incarceration. In multivariable GEE analyses, younger age (adjusted odds ratio [AOR] = 1.04 per year younger, 95 % confidence interval [CI] 1.02-1.06), being of a sexual/gender minority (AOR = 1.62, 95 % CI 1.13-2.34), heavy drinking (AOR = 1.99, 95 % CI 1.20-3.29), being born in Canada (AOR = 3.28, 95 % CI 1.26-8.53), living in unstable housing conditions (AOR = 4.32, 95 % CI 2.17-8.62), servicing clients in public spaces (versus formal sex work establishments) (AOR = 2.33, 95 % CI 1.05-5.17) and experiencing police harassment without arrest (AOR = 1.82, 95 % CI 1.35-2.45) remain independently correlated with incarceration. This prospective study found a very high prevalence and frequency of incarceration among women sex workers in Vancouver, Canada, with the most vulnerable and marginalized women at increased risk of incarceration. Given the well-known social and health harms associated with incarceration, and associations between police harassment and incarceration in this study, our findings further add to growing calls to move away from criminalized and enforcement-based approaches to sex work in Canada and globally.

Sex Work and Motherhood: Social and Structural Barriers to Health and Social Services for Pregnant and Parenting Street and Off-Street Sex Workers

Our study documents the correlates of barriers to pregnancy and mothering among sex workers in Vancouver, Canada. We used baseline data from An Evaluation of Sex Workers' Health Access (AESHA), a prospective cohort of sex workers. Among the 399 sex workers who had ever been pregnant or had a child, 35% reported having ever experienced a barrier, with lower education, homelessness, and history of injecting drugs significantly correlated with pregnancy and mothering barriers. Our findings highlight a critical need for tailored and nonjudgmental services and supports, including improved programs to address intersecting aspects of poverty, health literacy, stigma, and substance use.

The Cedar Project: Residential transience and HIV vulnerability among young Aboriginal people who use drugs

Aboriginal homelessness is considered to be a result of historic dispossession of traditional territories and forced displacement from community structures. Using data collected from 2005-2010 from the Cedar Project, a cohort of young Aboriginal people who use drugs in two Canadian cities, we examined how residential transience shapes HIV vulnerability. At baseline, 48 of 260 participants (18.5%) reported sleeping in six or more places ('highly transient') in the past six months. Generalized linear mixed models identified associations between high transience and sex and drug related HIV vulnerabilities. Transience was independently associated with sex work (AOR:3.52, 95%CI:2.06, 6.05); sexual assault (AOR:2.48, 95%CI:1.26, 4.86); injection drug use (AOR:4.54, 95%CI:2.71, 7.61); daily cocaine injection (AOR:2.16, 95%CI:1.26, 3.72); and public injection (AOR:2.87, 95%CI:1.65, 5.00). After stratification, transience and sexual vulnerability remained significantly associated among women but not men. Ensuring that young Aboriginal people have access to safe spaces to live, work, and inject must include policies addressing residential transience as well as the absence of a roof and walls.

Exploring HIV prevention strategies among street-based female sex workers in Chongqing, China

Background: Commercial sex plays an increasingly important role in China’s growing HIV and sexually transmitted infection (STI) epidemics. In China, street-based sex workers (SSWs) are a subgroup of female sex workers with a particularly high risk of HIV/STI infections but are neglected in responses to HIV. This study assesses changes in HIV voluntary counseling and testing (VCT) utilization and high-risk sexual behaviors following a three-month HIV preventive intervention among SSWs in Chongqing, China. Methods: A three-month intervention was conducted by a team of peer educators, outreach workers from community-based organizations and health professionals. It mainly included distribution of free pamphlets and condoms and delivery of onsite and clinic-based VCT. Cross-sectional surveys were conducted prior to (n = 100) and immediately following (n = 112) the intervention to assess its impact. In-depth interviews were conducted among 12 SSWs after the intervention to further explore potential barriers to HIV prevention. Results: The intervention significantly increased SSWs’ participation in VCT (from 2.0%–15.2%, P < 0.001). Despite participants’ improved HIV-related knowledge level (from 24.0%–73.2%, P < 0.001), there were minimal changes in the levels of condom use with clients. Qualitative research revealed that fear of police arrest and stigma were the main barriers to VCT utilization. Low condom use was associated with family financial constraints, inadequate power in condom negotiation, low awareness and misconceptions of HIV infection risks. Conclusion: HIV intervention improved VCT utilization and knowledge but we did not observe an increase in condom use after this short intervention. SSWs faced substantial economic, social and environmental barriers to VCT utilization and condom use.

High prevalence and partner correlates of physical and sexual violence by intimate partners among street and off-street sex workers

Objectives

Intimate partner violence (IPV) is associated with increased risk of HIV among women globally. There is limited evidence and understanding about IPV and potential HIV risk pathways among sex workers (SWs). This study aims to longitudinally evaluate prevalence and correlates of IPV among street and off-street SWs over two-years follow-up.

Methods

Longitudinal data were drawn from an open prospective cohort, AESHA (An Evaluation of Sex Workers Health Access) in Metro Vancouver, Canada (2010–2012). Prevalence of physical and sexual IPV was measured using the WHO standardized IPV scale (version 9.9). Bivariate and multivariable logistic regression using Generalized Estimating Equations (GEE) were used to examine interpersonal and structural correlates of IPV over two years.

Results

At baseline, 387 SWs had a male, intimate sexual partner and were eligible for this analysis. One-fifth (n = 83, 21.5%) experienced recent physical/sexual IPV at baseline and 26.2% over two-years follow-up. In multivariable GEE analysis, factors independently correlated with physical/sexual IPV in the last six months include: childhood (<18 years) sexual/physical abuse (adjusted odds ratio [AOR] = 2.05, 95% confidence interval [CI]: 1.14–3.69), inconsistent condom use for vaginal and/or anal sex with intimate partner (AOR = 1.84, 95% CI: 1.07–3.16), <daily prescription opioid use (AOR = 1.72, 95% CI: 1.02–2.89), providing financial support to intimate partner (AOR = 1.65, 95% CI: 1.05–2.59), and sourcing drugs from intimate partner (AOR = 1.62, 95% CI: 1.02–2.26).

Discussion

Our results demonstrate that over one-fifth of SWs in Vancouver report physical/sexual IPV in the last six months. The socio-structural correlates of IPV uncovered here highlight potential HIV risk pathways through SWs’ intimate, non-commercial partner relationships. The high prevalence of IPV among SWs is a critical public health concern and underscores the need for integrated violence and HIV prevention and intervention strategies tailored to this key population.

Youth, violence and non-injection drug use: nexus of vulnerabilities among lesbian and bisexual sex workers

Despite increasing evidence of enhanced HIV risk among sexual minority populations, and sex workers (SWs) in particular, there remains a paucity of epidemiological data on the risk environments of SWs who identify as lesbian or bisexual. Therefore, this short report describes a study that examined the individual, interpersonal and structural associations with lesbian or bisexual identity among SWs in Vancouver, Canada. Analysis drew on data from an open prospective cohort of street and hidden off-street SWs in Vancouver. Bivariate and multivariable logistic regressions were used to examine the independent relationships between individual, interpersonal, work environment and structural factors and lesbian or bisexual identity. Of the 510 individuals in our sample, 95 (18.6%) identified as lesbian or bisexual. In multivariable analysis, reporting non-injection drug use in the last six months (adjusted odds ratio [AOR] = 2.89; 95% confidence intervals [CI] = 1.42, 5.75), youth ≤24 years of age (AOR = 2.43; 95% CI = 1.24, 4.73) and experiencing client-perpetrated verbal, physical and/or sexual violence in the last six months (AOR = 1.85; 95% CI = 1.15, 2.98) remained independently associated with lesbian/bisexual identity, after adjusting for potential confounders. The findings demonstrate an urgent need for evidence-based social and structural HIV prevention interventions. In particular, policies and programmes tailored to lesbian and bisexual youth and women working in sex work, including those that prevent violence and address issues of non-injection stimulant use are required.

Negotiating place and gendered violence in Canada's largest open drug scene

BACKGROUND

Vancouver's Downtown Eastside is home to Canada's largest street-based drug scene and only supervised injection facility (Insite). High levels of violence among men and women have been documented in this neighbourhood. This study was undertaken to explore the role of violence in shaping the socio-spatial relations of women and 'marginal men' (i.e., those occupying subordinate positions within the drug scene) in the Downtown Eastside, including access to Insite.

METHODS

Semi-structured qualitative interviews were conducted with 23 people who inject drugs (PWID) recruited through the Vancouver Area Network of Drug Users, a local drug user organization. Interviews included a mapping exercise. Interview transcripts and maps were analyzed thematically, with an emphasis on how gendered violence shaped participants' spatial practices.

RESULTS

Hegemonic forms of masculinity operating within the Downtown Eastside framed the everyday violence experienced by women and marginal men. This violence shaped the spatial practices of women and marginal men, in that they avoided drug scene milieus where they had experienced violence or that they perceived to be dangerous. Some men linked their spatial restrictions to the perceived 'dope quality' of neighbourhood drug dealers to maintain claims to dominant masculinities while enacting spatial strategies to promote safety. Environmental supports provided by health and social care agencies were critical in enabling women and marginal men to negotiate place and survival within the context of drug scene violence. Access to Insite did not motivate participants to enter into "dangerous" drug scene milieus but they did venture into these areas if necessary to obtain drugs or generate income.

CONCLUSION

Gendered violence is critical in restricting the geographies of men and marginal men within the street-based drug scene. There is a need to scale up existing environmental interventions, including supervised injection services, to minimize violence and potential drug-related risks among these highly-vulnerable PWID.

Sex-for-Crack exchanges: associations with risky sexual and drug use niches in an urban Canadian city

Background

While crack cocaine has been associated with elevated sexual risks and transmission of HIV/STIs, particularly in the context of street-based sex work, few empirical studies have examined correlates of direct sex-for-crack exchanges. This study longitudinally examined the correlates of sex-for-crack exchanges and associated effects on sexual risk outcomes among street-based female sex workers (SW) who use drugs in Vancouver, Canada.

Methods

Data were drawn from a prospective cohort of street-based SWs (2006–2008), restricted to those who smoke crack cocaine. Multivariable generalized estimating equations (GEE) were employed to examine the correlates of exchanging sex for crack. A confounding model using GEE quasi-Poisson regression modeled the independent effect of exchanging sex for crack on number of clients/week.

Results

Of 206 SWs, 101 (49%) reported sex-for-crack exchanges over 18 months of follow-up. In multivariable GEE analyses, sharing a crack pipe with a client (aOR = 1.98; 95%CI: 1.27-3.08) and smoking crack in a group of strangers (e.g., in an alley or crackhouse) (aOR = 1.70; 95% CI: 1.13-2.58) were independently correlated with sex-for-crack exchanges. In our confounding model, exchanging sex for crack (aIRR = 1.34; 95% CI: 1.07-1.69) remained significantly associated with servicing a greater number (>10) of clients/week.

Conclusions

These findings reveal elevated sexual- and drug- risk patterns among those who exchange sex for crack. The physical and social environment featured prominently in our results as a driver of sex-for-crack exchanges, highlighting the need for gender-sensitive multilevel approaches to harm reduction, STI and HIV prevention that address SWs’ environment, individual level factors, and the interplay between them.

Risky health environments: women sex workers' struggles to find safe, secure and non-exploitative housing in Canada's poorest postal code

This study explored low-income and transitional housing environments of women sex workers and their role in shaping agency and power in negotiating safety and sexual risk reduction in Vancouver, Canada. A series of 12 focus group discussions were conducted with 73 women currently involved in street-based sex work. These women were purposively sampled for a range of experiences living in low-income housing environments, including homeless shelters, transitional housing, and co-ed and women-only single-room occupancy (SRO) hotels. Drawing on the risk environment framework and theoretical constructs of gender, agency and power, analyses demonstrate that women continue to be vulnerable to violence and sexual and economic exploitation and have reduced ability to negotiate risk reduction resulting from the physical, structural and social environments of current dominant male-centred housing models. Within the physical environment, women described inhabitable housing conditions in SROs with infestations of bedbugs and rats, leading women to even more transitional housing options such as shelters and couch-surfing. In many cases, this resulted in their economic exploitation and increased sexual risk. Within the structural environment, enforcement of curfews and guest policies forced women to accept risky clients to meet curfew, or work outdoors where their ability to negotiate safety and condom use were limited. Certain policies promoted women's agency and mitigated their ability to reduce risks when selling sex. These included flexible curfews and being able to bring clients home. The social environments of co-ed single-room occupancy hotels resulted in repeated violence by male residents and discrimination by male building staff. Women-only shelters and SROs facilitated 'enabling environments' where women developed support systems with other working women that resulted in safer work practices. The narratives expressed in this study reveal the critical need for public health interventions and safer supportive housing to account for the daily lived experiences of women sex workers.
