Severe Food Insecurity, Gender-Based Violence, Homelessness, and HIV Risk among Street-based Female Sex Workers in Baltimore, Maryland

Condom Use at Last Sex and Sexual Negotiation Among Young African American Women in North Carolina: Context or Personal Agency

African American women are 10.8 times more likely to be diagnosed with HIV compared with White women. This descriptive study fills a gap by examining associations among social and contextual factors and sexual communication, condom use, and safer sex negotiation among African American women. Study participants between 18 and 25 years of age and who reported recent substance use were recruited from three North Carolina counties. A risk behavior survey was administered via audio computer-assisted self-interview, and logistic regression analyses were conducted to assess associations between social and contextual variables and condom use at last sex with a main partner. Education (AOR: 2.078; 95% CI: 1.214, 3.556), sexual communication with a main partner (AOR: 1.079; 95% CI: 1.050, 1.109), and condom use relationship scale (AOR: 1.059; 95% CI: 1.023, 1.098) were positively associated with condom use at last sex, whereas living with a main partner (AOR: 0.447; 95% CI: 0.210, 0.950) and the alcohol and drug problem scale (AOR: 0.971; 95% CI: 0.944, 0.998) were negatively associated with condom use (p < 0.05). The study findings show that among young African American women at risk for HIV, contextual and personal factors may influence condom use. A socio-ecological approach combining personal empowerment, interpersonal, structural, and biobehavioral strategies is necessary in implementing holistic gender-focused HIV prevention programs.

Correlates of HIV Testing Among Asian Immigrant Female Sex Workers in New York City and Los Angeles County

This analysis examined correlates of HIV testing among Asian immigrant female sex workers in massage parlors. We interviewed 69 Chinese and Korean immigrant women who provided sexual services in massage parlors in New York City or Los Angeles County (2014-2016). Multivariable logistic regression results showed that participants who were younger, have lived in the U.S. for a longer period of time, had greater English proficiency, perceived higher HIV risk, or were living with an intimate partner were more likely to have had an HIV test. Disclosing sex work to a close friend was also positively associated with HIV testing at p < .1. These correlates may reflect differential access to information, systems, and social networks that would facilitate HIV testing, highlighting the importance of reducing social isolation and increasing HIV education, especially for older women who have come to the U.S. more recently. As the literature has indicated that Asian immigrant female sex workers experience high rates of intersectional stigma, efforts to mitigate these intersecting stigmas could further these objectives.

The Association Between Food Insecurity and Intimate Partner Violence Among U.S. Army Soldiers

Food insecurity in the military ranges between 25% and 33%, significantly higher than the 10.5% for civilians reported by the U.S. Department of Agriculture. The primary objective of this study is to analyze the association between food insecurity and intimate partner violence (IPV) victimization among U.S. Army Soldiers. The secondary objective is to determine if there are any moderating effects in the relationship between food insecurity and IPV victimization by demographic, financial, and mental health covariates. A cross-sectional, online survey was administered by the U.S. Army Public Health Center at an Army installation in 2019; 56% of respondents reported that they were married or in a relationship (n = 2,740). The main predictor was the two-item food insecurity screener (Hunger Vital Signs), which measures marginal food insecurity (encompassing marginal, low, and very low food security). The main outcome was IPV victimization as measured by the Hurt, Insult, Threaten, Scream scale. Multiple logistic regression was used to assess the association between marginal food insecurity and IPV victimization, controlling for demographic, financial, and mental health covariates. In a multivariable model, marginally food insecure respondents had 2.05-fold greater adjusted odds of reporting any IPV victimization when compared to highly food secure respondents (95% confidence interval [1.40, 3.00]). The only interaction that was statistically significant was between anxiety and food insecurity on IPV victimization (p = .0034). Interactions by soldier's military rank, birth sex, and race and ethnicity were not statistically significant. IPV has implications for the emotional and physical health of survivors. In addition, service members who are food insecure may experience similar decrements in emotional and physical health due to suboptimal nutrient intake. By addressing both food insecurity and IPV, the military has the potential to increase the overall well-being of its service members and their dependents.

The Link Between Intimate Partner Violence and Food Insecurity: A Review of Quantitative and Qualitative Studies

Intimate partner violence (IPV) and food insecurity are global health issues that affect millions of people worldwide. Numerous studies show that IPV and food insecurity are linked; however, there is a lack of synthesis of this research. Using a systematic search and review, we examined the international quantitative and qualitative research published on the link between IPV and food insecurity. We searched for peer-reviewed, English-language articles with participants above the age of 16 in 4 large online databases. Fifty-six studies were included from around the world that discussed the link between food insecurity and IPV perpetration and/or victimization. We found evidence in both qualitative and quantitative studies for a meaningful connection between these two global health isues. We also reviewed the literature on moderators and mediators (e.g., mental health). Our findings indicate the importance of implementing IPV prevention strategies which also address household food insecurity, and the potential for food insecurity resources to provide IPV resources. Future research should focus more frequently on IPV perpetration as opposed to victimization, and further examine the moderating and mediating mechanisms that inform the link between IPV and food insecurity.

Causes of preventable death among children of female sex worker mothers in low- and middle-income countries: A community knowledge approach investigation

Background

Female sex workers (FSW) in low- and middle-income countries (LMIC) are disproportionately vulnerable to poor health, social, and economic outcomes. The children of female sex workers (CFSW) experience health risks based on these challenging circumstances and the unique conditions to which they are exposed. Although country child mortality data exist, little is known about the causes of death among CFSW specifically, thereby severely limiting an effective public health response to the needs of this high-risk group of children.

Methods

The Community Knowledge Approach (CKA) was employed between January and October 2019 to survey a criterion sample of 1280 FSW participants across 24 cities in eight LMIC countries. Participants meeting pre-determined criteria provided detailed reports of deaths among the CFSW within their community of peers. Newborn deaths were gleaned from FSW maternal death reports where the infants also died following birth.

Results

Of the 668 child deaths reported, 589 were included in the analysis. Nutritional deficiencies comprised the leading cause of mortality accounting for 20.7% of deaths, followed closely by accidents (20.0%), particularly house fires, overdoses (19.4%), communicable diseases (18.5%), and homicides (9.8%). Other reported causes of death included neonatal conditions, respiratory illnesses, and suicides.

Conclusions

The causes of CFSW death in these eight countries are preventable with improved protections. Governments, intergovernmental organisations like the United Nations, nongovernmental stakeholder organisations (e.g. sex worker organisations), and funders can implement targeted policies and programmes to protect CFSW and assist vulnerable FSW who are pregnant and raising children. Further research is needed to identify effective child welfare safeguards for CFSW.

A Longitudinal Analysis of Residential Mobility and Experience of Client Violence Among Women Who Exchange Sex in Baltimore

Residential mobility remains an underexplored yet critical construct that may influence the risk of violence among women who exchange sex. This study examined the longitudinal relationship between residential mobility and experience of client-perpetrated physical or sexual violence among women who exchange sex in Baltimore, Maryland. Participants were at least at 18 years of age, were cisgender women, reported having engaged in transactional sex three or more times within the last 3 months, and were willing to be contacted for 6-, 12-, and 18-month follow-up visits. Analyses of responses from 370 women who exchange sex participating in at least one study visit were conducted. Unadjusted and adjusted Poisson regression models of the association over time between residential mobility and recent experience of physical or sexual violence were fit. Generalized estimating equations with an exchangeable correlation structure and robust variance estimation were used to account for clustering of participants' responses over time. Findings demonstrated that those who had lived in at least four places in the past 6 months had a 39% increased risk of client-perpetrated physical violence (aRR: 1.39; 95% CI: 1.07-1.80; p < .05) and a 63% increased risk of sexual violence (aRR: 1.63; 95% CI: 1.14-2.32; p < .01) compared to their less-mobile counterparts. These findings provide necessary evidence of correlations over time between residential mobility and experience of client-perpetrated violence among women who exchange sex. Strengthening our understanding of how residential mobility intersects with violence is critical for the development of public health interventions that are relevant to women's lives and needs. Future interventions should explore including residential mobility, a critical pillar of housing instability, with efforts to address client-perpetrated violence.

Food Insecurity and Transmission Risks Among People with HIV Who Use Substances

Food insecurity (FI) impacts people with HIV (PWH) and those who use substances (i.e. drugs and alcohol). We evaluated the longitudinal association between FI and HIV transmission risks (unprotected sexual contacts and shared needles/syringes). Among 351 PWH who use substances in Russia, 51.6% reported FI and 37.0% past month injection drug use. The mean number of unprotected sexual contacts in the past 90 days was 13.4 (SD 30.1); 9.7% reported sharing needles/syringes in the past month. We did not find a significant association between mild/moderate FI (adjusted IRR = 0.87, 95% CI 0.47, 1.61) or severe FI (aIRR = 0.84, 95% CI 0.46, 1.54; global p = 0.85) and unprotected sexual contacts. We observed a significant association between severe FI and sharing needles/syringes in the past month (adjusted OR = 3.27, 95% CI 1.45, 7.39; p = 0.004), but not between mild/moderate FI and sharing needles/syringes in the past month (aOR = 1.40,95% CI 0.58, 3.38; p = 0.45). These findings suggest that severe FI could be a potential target for interventions to lower HIV transmission.

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.

Who Asks About HIV/STI Status?: An Analysis of Women Who Sell Sex and Inject Drugs

Communication about HIV and sexually transmitted infections (STI) is a cornerstone of risk reduction, yet there is a dearth of research that examines communication patterns among persons with dual risks for HIV/STI acquisition, such as women who sell sex and inject drugs (WSSID). We used logistic regression to identify factors associated with WSSID (N = 211) in Baltimore, Maryland always asking new clients about their HIV/STI status. Most WSSID were non-Hispanic White (73%) and 74% reported current homelessness. 50% of WSSID reported always asking new clients about their HIV/STI status. Experiencing depressive symptoms (adjusted odds ratio [aOR]: 0.53; 95% confidence interval [CI]: 0.29, 0.96) and having condomless sex with clients (aOR 0.31; 95% CI: 0.17, 0.57) were inversely associated with WSSID always asking new clients about their HIV/STI status. Recent entry into sex work (aOR 2.99; 95% CI: 1.30, 6.87) was positively associated with always asking new clients about their HIV/STI status. Enhancing HIV/STI communication in combination with engagement in other risk mitigation strategies may decrease disease incidence among WSSID.

Mental health and HIV risk differs by co-occurring structural vulnerabilities among women who sell sex

Female sex workers (FSW) experience many structural vulnerabilities (SV; e.g., violence, economic insecurity) which contribute to increased risk of HIV and mental distress. However, little research has examined how SV co-occur to shape HIV risk, and none have studied mental distress. Among FSW (n = 385) in Baltimore, Maryland, latent class analysis of five binary indicators (housing insecurity; financial dependence on others; client-perpetrated physical or sexual violence; food insecurity) determined classes of SV and differential HIV risk behavior and mental health outcomes. A 3-class model fit the data best: minimal SV (i.e., low probabilities of all indicators); material needs (i.e., housing, food insecurity); and high SV (i.e., high probability of all indicators). Compared to minimal SV, high SV and material needs had significantly greater adjusted probability of drug injection and poorer adjusted depression, post-traumatic stress disorder, and mental distress scores. The high SV class had significantly higher probability of reporting condomless sex with clients compared to material needs and minimal SV. Results show the deleterious effect of co-occurring SV on HIV risk behaviors among FSW with particular emphasis on co-occurring food and housing insecurities. This is the first study of co-occurring SV on mental health outcomes in this key population.

Criminalization and coercion: sexual encounters with police among a longitudinal cohort of women who exchange sex in Baltimore, Maryland

BACKGROUND

The criminalization of sex work and drug use creates unequal power dynamics easily exploited by police. Women who exchange sex (WES) in settings around the globe have reported coerced sex and sexual assault by police, and some have reported police as paying clients. Little research has examined nuances underlying WES's sexual interactions with police.

METHODS

A cohort of cisgender WES (N = 308) was recruited through targeted sampling in Baltimore, Maryland and completed a structured survey every 6 months for 18 months. Follow-up surveys included detailed questions about recent sexual encounters with police. In bivariate and multivariate models using generalized estimating equations to account for intra-person correlation, we examined correlates of reporting recent sex with police over time.

RESULTS

One-third reported recent sex with police at any study visit. At each time point, about 90% of women who reported sex with police reported any uniformed or non-uniformed police had paid for sex. Between 72 and 85% had been solicited for paid sex by uniformed police. Between 41 and 50% of women who reported recent sex with police indicated they had done so because they feared arrest otherwise; one-third were directly pressured for sex by police to avoid arrest or trouble. In the final adjusted model, severe food insecurity [adjusted odds ratio (aOR) = 2.05; 95% confidence interval (CI) 1.13-3.71], Black race (vs. white, non-Hispanic; aOR = 1.90; 95% CI 1.13-3.17), recent arrest (aOR = 1.51; 95% CI 1.01-2.27), nonfatal overdose (aOR = 1.94; 95% CI 1.24-3.01), and client- or non-paying intimate partner-perpetrated violence (aOR = 2.46; 95% CI 1.63-3.71) were significantly independently associated with recent sex with police.

CONCLUSIONS

Sexual encounters between WES and police in Baltimore are common and often coerced to avoid arrest in a setting where both drug use and sex work are criminalized. Recent sex with police was more prevalent among WES who were racially marginalized, highly structurally vulnerable, and/or at high risk for drug overdose-and therefore subject to the dual-criminalization of sex work and drug use. This indicates deep power imbalances and their exploitation by police as the root of such sexual encounters and adds to the evidence regarding the need for decriminalization to support the health and wellbeing of WES.

Inferred networks, machine learning, and health data

This paper presents a network science approach to investigate a health information dataset, the Sexual Acquisition and Transmission of HIV Cooperative Agreement Program (SATHCAP), to uncover hidden relationships that can be used to suggest targeted health interventions. From the data, four key target variables are chosen: HIV status, injecting drug use, homelessness, and insurance status. These target variables are converted to a graph format using four separate graph inference techniques: graphical lasso, Meinshausen Bühlmann (MB), k-Nearest Neighbors (kNN), and correlation thresholding (CT). The graphs are then clustered using four clustering methods: Louvain, Leiden, and NBR-Clust with VAT and integrity. Promising clusters are chosen using internal evaluation measures and are visualized and analyzed to identify marker attributes and key relationships. The kNN and CT inference methods are shown to give useful results when combined with NBR-Clust clustering. Examples of cluster analysis indicate that the methodology produces results that will be relevant to the public health community.

Economic Abuse and Care-seeking Practices for HIV and Financial Support Services in Women Employed by Sex Work: A Cross-Sectional Baseline Assessment of a Clinical Trial Cohort in Uganda

Economic hardship is a driver of entry into sex work, which is associated with high HIV risk. Yet, little is known about economic abuse in women employed by sex work (WESW) and its relationship to uptake of HIV prevention and financial support services. This study used cross-sectional baseline data from a multisite, longitudinal clinical trial that tests the efficacy of adding economic empowerment to traditional HIV risk reduction education on HIV incidence in 542 WESW. Mixed effects logistic and linear regressions were used to examine associations in reported economic abuse by demographic characteristics, sexual behaviors, HIV care-seeking, and financial care-seeking. Mean age was 31.4 years. Most WESW were unmarried (74%) and had less than primary school education (64%). 48% had savings, and 72% had debt. 93% reported at least one economic abuse incident. Common incidents included being forced to ask for money (80%), having financial information kept from them (61%), and being forced to disclose how money was spent (56%). WESW also reported partners/relatives spending money needed for bills (45%), not paying bills (38%), threatening them to quit their job(s) (38%), and using physical violence when earning income (24%). Married/partnered WESW (OR = 2.68, 95% CI:1.60-4.48), those with debt (OR = 1.70, 95% CI:1.04-2.77), and those with sex-work bosses (OR = 1.90, 95% CI:1.07-3.38) had higher economic abuse. Condomless sex (β = +4.43, p < .05) was higher among WESW experiencing economic abuse, who also had lower odds of initiating PrEP (OR = .39, 95% CI:.17-.89). WESW experiencing economic abuse were also more likely to ask for cash among relatives (OR = 2.36, 95% CI:1.13-4.94) or banks (OR = 2.12, 95% CI:1.11-4.03). The high prevalence of HIV and economic abuse in WESW underscores the importance of integrating financial empowerment in HIV risk reduction interventions for WESW, including education about economic abuse and strategies to address it. Programs focusing on violence against women should also consider economic barriers to accessing HIV prevention services.

Selling sex in the context of substance use: social and structural drivers of transactional sex among men who use opioids in Maryland

BACKGROUND

Transactional sex is an important driver of HIV risk among people who use drugs in the USA, but there is a dearth of research characterizing men's selling and trading of sex in the context of opioid use. To identify contextually specific factors associated with selling or trading sex in a US population of men who use drugs, we cross-sectionally examined social and structural correlates of transactional sex among men who use opioids (MWUO) in Anne Arundel County and Baltimore City, Maryland.

METHODS

Between July 2018 and March 2020, we used targeted sampling to recruit men reporting past-month opioid use from 22 street-level urban and suburban recruitment zones. MWUO completed a 30-min self-administered interview eliciting substance use histories, experiences with hunger and homelessness, criminal justice interactions, and transactional sex involvement. We identified correlates of recent (past 3 months) transactional sex using multivariable log-binomial regression with cluster-robust standard errors.

RESULTS

Among 422 MWUO (mean age 47.3 years, 73.4% non-Hispanic Black, 94.5% heterosexual), the prevalence of recent transactional sex was 10.7%. In multivariable analysis, younger age (adjusted prevalence ratio [aPR] 0.98, 95% confidence interval [95% CI] 0.97-0.99, p < 0.001), identifying as gay/bisexual (aPR = 5.30, 95% CI 3.81-7.37, p < 0.001), past-month food insecurity (aPR = 1.77, 95% CI 1.05-3.00, p = 0.032), and injection drug use in the past 3 months (aPR = 1.75, 95% CI 1.02-3.01, p = 0.043) emerged as statistically significant independent correlates of transactional sex.

CONCLUSIONS

Synergistic sources of social and structural marginalization-from sexuality to hunger, homelessness, and injection drug use-are associated with transactional sex in this predominantly Black, heterosexual-identifying sample of MWUO. Efforts to mitigate physical and psychological harms associated with transactional sex encounters should consider the racialized dimensions and socio-structural drivers of transactional sex among MWUO.

Economic vulnerability, violence, and sexual risk factors for HIV among female sex workers in Tijuana, Mexico

Economic vulnerability is often reported to underlie involvement in sex work among female sex workers (FSW), but may also create urgency in women's work, limiting women's negotiating power with clients and in turn, increasing their vulnerability for violence and HIV. This study assessed economic vulnerability in relation to violence and sexual risk behaviors for HIV among a sample of FSW in Tijuana, Mexico. FSW at least 18 years of age were recruited through venue-based sampling for a survey (n = 228) and in-depth interviews (n = 50) to investigate HIV risk factors in this region. Using crude and adjusted logistic regression models, we assessed lack of financial support from others as well as reports of financial hardship separately in relation to experiencing sexual violence (e.g. by clients, police, relationship partners, in the past 6 months), physical violence (past 6 months), STI diagnosis, and inconsistent condom use (past 30 days). Qualitative interviews (n = 50), conducted with a subsample of the survey participants, were also examined for related themes. FSW who reported no financial support were more likely to report sexual violence (OR = 2.1; 95% CI:1.1-4.2). FSW who reported financial hardship were more likely to experience sexual violence (OR = 1.9; 95% CI:1.1-3.6) and physical violence (OR = 1.9; 95% CI:1.1-3.6), as well as to report past 30-day inconsistent condom use (OR = 2.4; 95%CI: 1.3-4.6) and to test positive for an STI (OR = 1.9; 95% CI:1.1-3.4). Qualitative data substantiated these findings. Findings suggest that interventions to improve economic well-being may be useful to prevent the intersecting concerns of violence and HIV among FSW.

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.

Mapping Interests in Event-Driven and Long-Acting Pre-exposure Prophylaxis Formulations onto the HIV Risk Environment of Street-Based Female Sex Workers: A Latent Class Analysis

Despite growing availability, HIV pre-exposure prophylaxis (PrEP) uptake and adherence remains suboptimal among female sex workers (FSW) in the United States. Using cross-sectional data from a survey of 236 street-based cisgender FSW in Baltimore, Maryland, we examined interest in event-driven and long-acting PrEP formulations. Latent class analysis identified discrete patterns of interest in five novel PrEP agents. Multinomial latent class regression then examined factors associated with probabilistic class membership. A three-class solution emerged as the best-fit latent class model: Injectable Acceptors (~ 24% of sample), Universal Acceptors (~ 18%), and Non-Acceptors (~ 58%). Compared to Non-Acceptors, Universal Acceptors had significantly (p < 0.05) higher odds of reporting condomless vaginal sex with clients, client condom coercion, and client-perpetrated physical violence. Relative to Non-Acceptors, Injectable Acceptors were distinguished by significantly higher rates of condomless vaginal sex with clients and injection drug use. Expanding PrEP options for FSW could help overcome barriers to PrEP initiation and persistence.

Co-occurring Threats to Agency Among Female Sex Workers in Baltimore, Maryland

Driven largely by the unequal distribution of power, female sex workers (FSW) globally bear a disproportionately high burden of HIV, sexually transmitted infections, and interpersonal violence. Prior literature has identified a number of multi-level factors that may serve to constrain FSWs' agency, or their ability to define and take action to realize goals. Among these are work-based violence and substance use, which are potentiated by the criminalization of sex work and structural vulnerability. Quantitative research related to U.S.-based FSWs' own sense of agency, as well as the barriers that may impede it, is sparse. We sought to identify patterns of various threats to agency and explore to what extent they were associated with perceived agency among a cohort of 381 FSW in Baltimore, Maryland, United States, using latent class analysis. Latent class indictors were past-six-month experience of client-perpetrated sexual violence, client-perpetrated physical violence, homelessness, food insecurity, arrest, daily crack-cocaine use, and daily heroin use. Perceived agency was measured using the short form of the Pearlin Mastery Scale. We identified three typologies of threatened agency among women in our sample: a "threatened by structural factors, drug use, and violence" class, a "threatened by structural factors and drug use" class, and a "less threatened" class. Mean perceived agency score was significantly lower for the class characterized by client-perpetrated violence than for either of the other classes. This suggests violence, in the context of deeper, structural power imbalances embedded in hunger, homelessness, and drug use, may dramatically reduce one's sense of agency and operate as a critical barrier to empowerment. Our study adds important insights to the broader FSW community empowerment literature and supports the need for interventions to bolster both individual and collective agency among U.S.-based FSW, including interventions to prevent sex work-related violence.

Latent Classes of Polysubstance Use and Associations with HIV Risk and Structural Vulnerabilities among Cisgender Women Who Engage in Street-Based Transactional Sex in Baltimore City

We describe patterns of polysubstance use and associations with HIV risk-related behaviors among women engaged in street-based transactional sex, an understudied yet important population and area of research. This sample was restricted to cisgender women who reported drug use (n = 244) in the baseline of the longitudinal SAPPHIRE cohort study. Latent class analysis (LCA) was conducted using drug use measures (route of administration (injection/non-injection); type of drug (specific opioids, stimulants)) and selection based on fit statistics and qualitative interpretation of the classes. Polysubstance use was prevalent (89% ≥ 2), and 68% had injected drugs in the past 3 months. A three-class solution was selected: Class 1 ("heroin/cocaine use", 48.4% of sample), Class 2 ("poly-opioid use", 21.3%), and Class 3 ("poly-route, polysubstance use", 30.3%). Class 3 was significantly younger, and Class 2 was disproportionately non-White. Women reported high levels of housing (63%) and food (55%) insecurity, condomless sex with clients (40%), and client-perpetrated violence (35%), with no significant differences by class. Obtaining syringes from syringe services programs differed significantly by class, despite injection behaviors in all classes. Tailored HIV and overdose prevention programming that considers drug use patterns would strengthen their impact.

ART uptake and adherence among female sex workers (FSW) globally: A scoping review

We conducted the first scoping literature review on ART uptake and adherence among Female Sex Workers (FSW), following PRISMA-ScR guidelines. Searches were conducted in PubMed, Embase, CINAHL, PsycInfo, and Sociological Abstracts. Eligibility criteria included: reporting an ART uptake or adherence result among FSW aged 18 or older; peer-reviewed; published in English between 1996 and 2018. Our search identified 6,735 studies; 30 met eligibility requirements. ART uptake ranges from 0 to 100% and adherence ranges from 50-90%, depending on measurement methods. Uptake and adherence influencing factors are mapped onto a social ecological model (SEM). Knowledge and beliefs, substance use, food insecurity and sex-work engagement were negatively associated, while older age, relationships and social support were positively associated with ART uptake and adherence. Standardised methods to measure uptake and adherence prevalence must be established for data comparison. Evidence regarding ART uptake and adherence barriers and facilitators span multiple SEM levels, although more research is needed regarding structural and occupational level influencers. Results suggest that the multi-level ART uptake and adherence barriers faced by FSW require complex multi-level evidence-based interventions. Study findings can inform ART interventions, future research, and offer guidance to other support services with FSW, such as PrEP interventions.

Social Support Associated with Condom Use Behavior Among Female Sex Workers in Iran

BACKGROUND

Despite the widespread knowledge about social support and health, there is little information about the association between social support and HIV risk behaviors such as condom use among female sex workers (FSWs) in Iran. This study aimed to determine the association between social support and frequency of condom use among FSWs in Tehran, Iran.

METHODS

Using mixed sampling methods, we recruited 170 FSWs in Tehran in 2017. We measured self-reported social support by face-to-face interviews using a standardized questionnaire. Linear regression was used to assess the association between socio-demographic characteristics (age, education level, marital status, and place of living), transactional sex characteristics (age at first transactional sex and frequency of transactional sex in the last month), HIV knowledge, social support network characteristics (social network size, duration of tie, intimacy, social support), and condom use behavior.

RESULTS

Of the total of 1193 persons in FSW's social networks, 615 (51%) were sexual partners, 529 (44%) were peer sex workers, and 36 (5%) were family members. The participants perceived moderate social support from sexual partners, low from peer sex workers, and very low from family members. Adjusted for individual and other network characteristics, peer sex worker social support (b = 0.28, 95%CI 0.06, 0.50), and family support (b = 1.12, 95%CI 0.028, 2.23) were significantly associated with condom use.

CONCLUSION

Family and peer sex worker social support are associated with condom use, but less strongly than HIV knowledge or place of living. However, very few FSWs are socially connected with families. Interventions to promote condom use among this vulnerable population should also consider social and familial support.

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.

Sex workers as mothers: Correlates of engagement in sex work to support children

BACKGROUND

Globally, most female sex workers (FSW) are mothers but are rarely considered as such in public health and social service programs and research. We aimed to quantitatively describe FSW who are mothers and to examine correlates of current engagement in sex work to support children among a cohort of FSW in Baltimore, Maryland, United States (U.S.).

METHODS

The study utilized baseline survey and HIV/STI testing data from the Sex workers And Police Promoting Health In Risky Environments (SAPPHIRE) study of women engaged in street-based sex work in Baltimore, Maryland. Variable selection and interpretation were guided by Connell's theory of Gender and Power. We used bivariate and multivariate logistic regression analyses to examine correlates of engagement in sex work to support children among FSW mothers.

RESULTS

Our sample included 214 FSW with children, of whom 27% reported supporting children as a reason for the current engagement in sex work. Median age was 36 years, and mean number of children was 2.88. 20.6% were currently living with any of their minor aged children, and this was significantly more common among mothers engaged in sex work to support children (57.9% vs. 7%; p<0.001). 38.7% had ever lost legal custody of children, which was significantly less common among those supporting children through sex work (26.8% vs. 42.9%; p=0.033). In multivariate analyses, the following were independently associated with engaging in sex work to support children: African-American versus white race (aOR=2.62; 95% CI:1.18-5.82; p=0.018); less housing instability (aOR=0.42; 95% CI:0.20-0.89; p=0.024); initiating sex work at age <23 (aOR=2.59; 95% CI:1.23-5.46; p=0.012); less frequent intoxication during sex with clients (aOR=0.31; 95% CI:0.14-0.67; p=0.003); and reporting mental health as most important health concern (aOR=2.37; 95% CI:1.09-5.17; p=0.029).

CONCLUSIONS

FSW mothers who report engagement in sex work to support children are distinct from their counterparts in key areas related to HIV and other health outcomes. Neglecting to account for this important social role may lead to missed opportunities to meaningfully promote physical and mental health and to engage women on their own terms. Future research and interventions should seek to address FSW as whole social beings and center their experiences and needs as mothers.

Food access among people who inject drugs in West Virginia

BACKGROUND

The substance use epidemic in the United States continues to drive high levels of morbidity and mortality, particularly among people who inject drugs (PWID). Poor access to food often co-occurs with drug use and contributes to associated sequelae, such as risks for HIV and diabetes. The objective of this study was to examine factors associated with adequate food access among PWID in a rural Appalachian community.

METHODS

Cross-sectional surveys were used to collect data among PWID aged 18 and older in Cabell County, West Virginia. Frequency of hunger and sociodemographic, structural and drug use characteristics were measured. Adequate food access was defined as reporting 'never' going to bed hungry at night in the past six months. Pearson's χ² and t-tests and multivariable logistic regression were used to identify factors associated with food access.

RESULTS

Only 71 individuals (17%) reported never going to bed hungry at night in the past six months. Adjusted odds of having adequate food access were higher among PWID who completed high school (aOR 2.94; P = 0.010) and usually used drugs alone (aOR 1.97; P = 0.025), and lower among PWID who were female (aOR 0.51; P = 0.037), experienced homelessness (aOR 0.23, P < 0.001), were recently arrested (aOR 0.50 P = 0.047), and engaged in receptive sharing of injection equipment (aOR 0.52, P = 0.035).

CONCLUSIONS

We found extremely low food access in a population of PWID in Appalachia who are vulnerable to overdose and infectious disease transmission. Integrated interventions promoting food access are needed to improve the public health and wellbeing of people who inject drugs in Appalachia.

Conceptualizing overdose trauma: The relationships between experiencing and witnessing overdoses with PTSD symptoms among street-recruited female sex workers in Baltimore, Maryland

BACKGROUND

The opioid crisis has rendered witnessing and experiencing overdoses a common occurrence, especially among marginalized and drug using populations, including female sex workers (FSW). Such exposures may confer psychological trauma that has gone unrecognized. We explored relationships between experiencing and witnessing overdoses and PTSD symptomology to understand the traumatic nature of these experiences.

METHODS

Data were from FSW (N = 380) in Baltimore City, Maryland, who reported whether they had witnessed/experienced any overdoses in the past 6 months ("overdose traumas") and PTSD symptoms (PCL-5). We tested for associations between overdose traumas and PTSD diagnoses/symptomology in bivariate logistic regression models and multivariate models, adjusting for sociodemographic, experiences of violence, and drug use characteristics.

RESULTS

In our sample, 35.3% witnessed a fatal overdose, 51.9% witnessed a non-fatal overdose, and 28.3% experienced an overdose in the past 6 months. More than half (52.4%) met criteria for PTSD. Most endorsed symptoms within each PTSD domain: 63.2% for intrusive, 58.4% for avoidance, 66.1% for cognition/mood, and 64.7% for arousal/reactivity symptoms. Experiencing an overdose was associated with meeting PTSD criteria and symptoms in all domains in bivariate models. Witnessing an overdose was associated with PTSD diagnoses and intrusive and arousal/reactivity symptoms in bivariate models. Adjusting for sociodemographic characteristics and drug use, experiencing an overdose was associated with intrusive and cognition/mood symptoms, while neither trauma remained associated with PTSD diagnoses.

CONCLUSIONS

Traumas related to overdose, coined "overdose traumas" appear to be extremely psychologically traumatic, though the relationships vary by type and symptom. Programs should be cognizant of psychological trauma to address the full spectrum of overdose harms. Existing measures of PTSD do not accurately represent the effects of overdose traumas in populations like FSW due to the structural barriers to avoiding locations/situations where overdoses may occur and the overlap between symptoms, drug effects, and adaptive responses to homelessness.

The EMERALD (Enabling Mobilization, Empowerment, Risk Reduction, and Lasting Dignity) Study: Protocol for the Design, Implementation, and Evaluation of a Community-Based Combination HIV Prevention Intervention for Female Sex Workers in Baltimore, Maryland

Background

Cisgender female sex workers (FSWs) experience high rates of HIV and sexually transmitted infections (STIs), including chlamydia and gonorrhea. Community empowerment–based responses to the risk environment of FSWs have been associated with significant reductions in HIV and STI risk and associated risk behaviors; however, evaluations of US-based interventions targeting FSWs are limited.

Objective

The objective of this study is to describe the design, implementation, and planned evaluation strategy of an ongoing comprehensive community-level intervention in Baltimore City, Maryland, which aims to improve HIV and STI risk and cumulative incidence among FSWs. The two intervention components are the SPARC (Sex Workers Promoting Action, Risk Reduction, and Community Mobilization) drop-in center and the accompanying comprehensive mobile outreach program. The mission of SPARC is to provide low-barrier harm reduction services to FSWs, with a special focus on women who sell sex and use drugs. Services are provided through a harm reduction framework and include reproductive health and sexual health care; medication-assisted treatment; legal aid; counseling; showers, lockers, and laundry; and the distribution of harm reduction tools, including naloxone and sterile drug use supplies (eg, cookers, cotton, syringes, and pipes).

Methods

The SPARC intervention is being evaluated through the EMERALD (Enabling Mobilization, Empowerment, Risk Reduction, and Lasting Dignity) study, which consists of a prospective 2-group comparative nonrandomized trial (n=385), a cross-sectional survey (n=100), and in-depth interviews assessing SPARC implementation (n=45). Participants enrolled in the nonrandomized trial completed a survey and HIV and STI testing at 4 intervals (baseline and 6, 12, and 18 months). Participants recruited from predefined areas closest to SPARC comprised the intervention group, and participants from all other areas of Baltimore were included in the control group.

Results

We hypothesize that addressing structural drivers and more immediate medical needs, in combination with peer outreach, will improve the HIV and STI risk environment, leading to community empowerment, and reduce the HIV and STI cumulative incidence and behavioral risks of FSWs. Data collection is ongoing. A baseline description of the cohort is presented.

Conclusions

In the United States, structural interventions aimed at reducing HIV and STIs among FSWs are scarce; to our knowledge, this is the first intervention of its kind in the United States. The results of the EMERALD study can be used to inform the development of future interventions targeting FSWs and other at-risk populations.

Why have Non-communicable Diseases been Left Behind?

Non-communicable diseases are no longer largely limited to high-income countries and the elderly. The burden of non-communicable diseases is rising across all country income categories, in part because these diseases have been relatively overlooked on the global health agenda. Historically, communicable diseases have been prioritized in many countries as they were perceived to constitute the greatest disease burden, especially among vulnerable and poor populations, and strategies for prevention and treatment, which had been successful in high-income settings, were considered feasible and often affordable in low-income settings. This prioritization has reduced the communicable diseases burden globally but has left non-communicable diseases largely neglected. A new approach is urgently needed to tackle non-communicable diseases. Based on an analysis of potential features which may have underlain the different approaches to non-communicable diseases and communicable diseases until now, including acuity of disease, potential for control or cure, cost, infectiousness, blaming of individuals and logistical barriers, little ethical or rational justification can be found to support continued neglect of non-communicable diseases. Justice demands access to quality and affordable care for all. An equitable approach to non-communicable diseases is therefore strongly mandated on medical, ethical, economic, and public health grounds. Funding must not however be diverted away from communicable diseases, which continue to require attention-but concomitantly, funding for non-communicable diseases must be increased. International and multi-sectoral action is required to accelerate progress towards true universal health coverage and towards achievement of all of the sustainable development goals, such that prevention and access to care for non-communicable disease can become a global reality.
