Identifying Patterns of Social and Economic Hardship Among Structurally Vulnerable Women: A Latent Class Analysis of HIV/STI Risk

Implementation of collaborative care for depression in VA HIV clinics: Translating Initiatives for Depression into Effective Solutions (HITIDES): protocol for a cluster-randomized type 3 hybrid effectiveness-implementation trial

BACKGROUND

Depression is the most diagnosed mental health condition among people living with HIV. Collaborative care is an effective intervention for depression, typically delivered in primary care settings. The HIV Translating Initiatives for Depression into Effective Solutions (HITIDES) clinical intervention involves a depression care team housed off-site that supports depression care delivery by HIV care providers. In a randomized controlled trial, HITIDES significantly improved depression symptoms for veterans living with HIV and delivered cost savings. However, no HIV clinics in the Veterans Health Administration (VHA) have implemented HITIDES; as such, it is unclear what implementation strategies are necessary to launch and sustain this intervention.

METHODS

This hybrid type-3 effectiveness-implementation trial examines the implementation and effectiveness of HITIDES in 8 VHA HIV clinics randomly assigned to one of two implementation arms. Each arm uses a different implementation strategy package. Arm 1 includes an intervention operations guide; an on-site clinical champion who, with the help of a peer community of practice, will work with local clinicians and leadership to implement HITIDES at their site; and patient engagement in implementation tools. Arm 2 includes all strategies from Arm 1 with assistance from an external facilitator. The primary implementation outcomes is reach; secondary outcomes include adoption, implementation dose, depressive symptoms, and suicidal ideation. We will conduct a budget impact analysis of the implementation strategy packages. We hypothesize that Arm 2 will be associated with greater reach and adoption and that Arm 1 will be less costly.

DISCUSSION

Preliminary work identified implementation strategies acceptable to veterans living with HIV and HIV care providers; however, the effectiveness and cost of these strategies are unknown. While the depression care team can deliver services consistently with high quality, the ability of the depression care team to engage with HIV care providers at sites is unknown. Findings from this study will be used to inform selection of implementation strategies for a broad rollout to enhance depression and suicide care for people living with HIV.

Keeping it real: A descriptive analysis of HIV testing history, PrEP awareness, and PrEP use among Black cisgender women in Middle Tennessee, 2018

INTRODUCTION

HIV disproportionately affects Black/African American women in the United States, particularly in the southern states, including Tennessee. Despite this, limited research and intervention are targeting this population, especially regarding biomedical prevention technologies such as pre-exposure prophylaxis (PrEP). This study aims to describe the HIV testing history of a sample of Black women in middle Tennessee, assess their awareness and potential for adopting modern HIV prevention technologies like PrEP, and explore the dyadic and social factors that influence their HIV prevention awareness and use.

THEORY

The Precaution Adoption Process Model (PAPM) is employed to understand how individuals progress through decision-making stages when adopting new health behaviors, especially related to novel interventions.

METHODS

For survey development and deployment, this cross-sectional survey study engaged the Nashville Health Disparities Coalition and the Resident Association for the Metropolitan Developmental Housing Association in Nashville. Eligible participants included African American and Black women aged 18 and above. The survey collected demographic information, HIV testing history, reasons for testing or not testing, dyadic HIV risk factors, awareness, and use of rapid HIV testing and PrEP, and social norms related to these prevention technologies.

RESULTS AND DISCUSSION

Age significantly influenced HIV testing history, emphasizing the importance of regular screening, especially among older women. Dyadic factors such as concurrency and having a shared male partner were associated with differences in testing behavior. Awareness of both rapid HIV testing and PrEP was limited among participants, highlighting the need for increased education and awareness campaigns specifically highlighting benefits to Black women. Social norms, particularly recommendations from healthcare providers, played a crucial role in influencing women's willingness to adopt these prevention technologies. [Increasing routine HIV testing and awareness of PrEP, especially among women in non-monogamous relationships, is essential in reducing HIV disparities among Black women.] IMPLICATIONS: Healthcare providers play a crucial role in initiating and recommending HIV testing and PrEP among Black women, emphasizing the importance of patient-provider relationships and ongoing conversations about prevention strategies. This study underscores the importance of community-engaged research in addressing HIV disparities and highlights the potential for partnerships between medical centers and community organizations in the fight against HIV.

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.

Using mindfulness-based stress reduction group therapy to reduce perceived stress of vulnerable women in south of Iran

Provision of educational and health services to vulnerable women in drop-in centers can reduce their traumas. Mindfulness-Based Stress Reduction (MBSR) group therapy is a psychological intervention to reduce perceived stress these women. This quasi-experimental study aimed to evaluate the effectiveness of MBSR group therapy in the perceived stress of 63 vulnerable women who referred to two drop-in centers in southeastern Iran. The participants were assigned into the intervention (n = 30) and control (n = 33) groups. The intervention group members were required to attend the MBSR intervention held in eight 90-minute sessions. Perceived Stress Scale (PSS) was administered to collect data before and one month after the MBSR. Based on the findings, the pre-test scores of perceived stress were not significantly different between the intervention (38.16 ± 6.04) and control (39.06 ± 5.30) groups (t = -0.62, p = 0.53). However, the perceived stress scores reduced significantly in the intervention group (30.20 ± 2.89) than the control group scores (37.96 ± 4.18) in the posttest (t = -8.35, P = 0.001). Given the significant reduction of perceived stress in participants after attending the MBSR group therapy, expert counselors, psychologists, and psychiatrists are recommended to conduct this therapy to reduce perceived stress in vulnerable women.

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.

Increasing HIV early diagnosis by implementing an automated screening strategy in emergency departments

INTRODUCTION

Late HIV diagnosis is associated with increased morbidity, mortality and risk of onward transmission. Increasing HIV early diagnosis is still a priority. In this observational study with historical control, we determined the impact of an opportunistic HIV screening strategy in the reduction of late diagnosis and missed opportunities for earlier diagnosis.

METHODS

The screening programme was implemented in the emergency department (ED) of the Hospital de Cascais between September 2018 and September 2021. Eligible patients were aged 18-64 years, with no known HIV diagnosis or antibody testing performed in the previous year, and who required blood work for any reason. Out of the 252 153 emergency visits to the ED, we identified 43 153 (17.1%) patients eligible for HIV testing. Among the total population eligible for the screening, 38 357 (88.9%) patients were ultimately tested for HIV. Impact of the ED screening was determined by analysing late diagnosis in the ED and missed opportunities at different healthcare settings 3 years before and 3 years after the start of the ED screening.

RESULTS

After 3 years of automated HIV ED testing, we found 69 newly diagnosed HIV cases (54% male, 39% Portuguese nationals, mean age 40.5 years). When comparing the characteristics of HIV diagnoses made in the ED, we observed a significant reduction in the number of people with late HIV diagnosis before and after implementation of the screening programme (78.4% vs. 39.1%, respectively; p = 0.0291). The mean number of missed opportunities for diagnosis also fell (2.6 vs. 1.5 annual encounters with the healthcare system per patient, p = 0.0997).

CONCLUSIONS

People living with HIV in Cascais and their providers miss several opportunities for earlier diagnosis. Opportunistic screening strategies in settings previously deemed to be unconventional, such as EDs, are feasible and effective in mitigating missed opportunities for timely HIV diagnosis.

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.

Cumulative Violence and PTSD Symptom Severity Among Urban Street-Based Female Sex Workers

Female sex workers (FSW) are a marginalized and vulnerable population at high risk of gender-based violence within and outside of their occupation. However, FSW remain underrepresented in the trauma and mental health literature. The aims of this study were to (a) characterize exposure to violence among street-based FSW, including violence type, patterns over the life course, and key perpetrator groups, and (b) examine the multivariate associations between posttraumatic stress disorder (PTSD) symptom severity and two constructs (revictimization across life stages and cumulative violence). Data were drawn from the Sex Workers and Police Promoting Health in Risky Environments (SAPPHIRE) study, an observational community-based cohort of street-based FSW recruited through targeted sampling across Baltimore, Maryland (USA) in 2016 to 2017. PTSD symptom severity was measured using the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (PCL-5). At baseline, 61% of FSW screened positive for PTSD symptoms. The mean PCL-5 score was 38.6. We documented extensive histories of sexual and physical violence (lifetime: 81.8%; childhood and adult revictimization: 15.0% for sexual and 37.7% for physical). The vast majority of perpetrators were male and included paying clients, police officers, family members, and intimate partners. Exposure to childhood and adult sexual violence were independently associated with higher PTSD severity (p < .05), with marginal associations observed for physical violence. Data supported a cumulative violence model of PTSD severity (p < .05). Binge drinking also appeared to be a contributing factor (p < .05). The levels of PTSD observed among our sample were comparable with that reported among treatment-seeking war veterans. Our findings underscore the urgent need for tailored trauma-informed interventions and policies to address violence among urban street-based FSW, a population experiencing extremely high levels of violence, PTSD, and substance use.

Place-Based Correlates of Exchange Sex Among People Who Inject Drugs in 19 U.S. Metropolitan Areas, 2012

This study examined overall and gender-specific associations between place-based characteristics and opposite-sex exchange sex among people who inject drugs (PWID) in the U.S. PWID were recruited from 19 metropolitan statistical areas (MSAs) for the Centers for Disease Control and Prevention's 2012 National HIV Behavioral Surveillance. Administrative data were used to describe the economic, social, and political features of the ZIP codes, MSAs, counties, and states where PWID lived. Multilevel modeling estimated associations of place characteristics and exchange sex. We found that 52% of women and 23% of men reported past-year opposite-sex exchange sex (N = 7599). Female PWID living in states with stronger policies supporting working caregivers had lower odds of exchange sex (aOR = 0.80; 95% CI 0.69, 0.94). PWID living in ZIP codes with greater economic deprivation had higher odds of exchange sex (aOR = 1.10; 95% CI 1.03, 1.17). We found that a high percentage of male PWID exchanged sex with women; determinants and risks of this group merit exploration. If future research establishes that the relationships identified here are causal, interventions to reduce exchange sex among PWID should include policies supporting working caregivers and reducing poverty rates.

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.

Prevalence and correlates of receptive syringe-sharing among people who inject drugs in rural Appalachia

BACKGROUND AND AIMS

Syringe-sharing significantly increases the risk of HIV and viral hepatitis acquisition among people who inject drugs (PWID). Clearer understanding of the correlates of receptive syringe-sharing (RSS) is a critical step in preventing bloodborne infectious disease transmission among PWID in rural communities throughout the United States. This study aimed to measure the prevalence and correlates of RSS among PWID in a rural county in Appalachia.

DESIGN

Observational, cross-sectional sample from a capture-recapture parent study.

SETTING

Cabell County, West Virginia (WV), USA, June-July 2018.

PARTICIPANTS

The sample was restricted to people who reported injecting drugs in the past 6 months (n = 420). A total of 180 participants (43%) reported recent (past 6 months) RSS. Participants reported high levels of homelessness (56.0%), food insecurity (64.8%) and unemployment (66.0%).

MEASUREMENTS

The main outcome was recent re-use of syringes that participants knew someone else had used before them. Key explanatory variables of interest, selected from the risk environment framework, included: unemployment, arrest and receipt of sterile syringes from a syringe services program (SSP). Logistic regression was used to determine correlates of recent RSS.

FINDINGS

PWID reporting recent RSS also reported higher prevalence of homelessness, food insecurity and unemployment than their non-RSS-engaging counterparts. In adjusted analyses, correlates of RSS included: engagement in transactional sex work [adjusted odds ratio (aOR) = 2.27, 95% confidence interval (CI) = 1.26-4.09], unemployment (aOR = 1.67, 95% CI = 1.03-1.72), number of drug types injected (aOR = 1.33, 95% CI = 1.15-1.53) and injection in a public location (aOR = 2.59, 95% CI = 1.64-4.08). Having accessed sterile syringes at an SSP was protective against RSS (aOR = 0.57, 95% CI = 0.35-0.92).

CONCLUSION

The prevalence of receptive syringe-sharing among people who inject drugs in a rural US county appears to be high and comparable to urban-based populations. Receptive syringe-sharing among people who inject drugs in a rural setting appears to be associated with several structural and substance use factors, including unemployment and engaging in public injection drug use. Having recently acquired sterile syringes at a syringe services program appears to be protective against receptive syringe sharing.

The Role of Sexually Transmitted Infections in Police as Clients Among Street-Based Female Sex Workers in Baltimore City

BACKGROUND

Research among street-based female sex workers (FSWs) has documented many harms caused by police. One harm that has received little attention is that of police as clients. We examined this interaction in a 12-month longitudinal cohort study of street-based FSWs in Baltimore, MD.

METHODS

We explored longitudinal bivariate and multivariate associations between having police clients and independent variables that focused on sexually transmitted infections (STIs), as well as demographic, structural, substance use, police interaction, and violence-related factors.

RESULTS

Mean participant age was 35.8 years, 65.9% were White, and more than half (53.3%) had less than a high school education. Most (70.3%) used heroin daily, and 24.8% reported having police as clients over the study period. In a multivariate model, factors independently associated with recent police clients were recent arrest (adjusted odds ratio [aOR], 1.76; 95% confidence interval [CI], 1.03-2.99; P = 0.037), coerced or forced sex by police (aOR, 4.47; 95% CI, 1.79-11.12; P = 0.001), higher number of egregious police practices experienced (aOR, 1.77; 95% CI, 1.38-2.29; P < 0.001), and prevalent STI infection (aOR, 2.43; 95% CI, 1.46-4.04; P = 0.001).

CONCLUSIONS

The study uniquely documents both the frequency with which street-based FSWs take police as clients and the role of egregious police practices and prevalent STIs in association with police as clients. Results indicate the police-as-client association as a form of "everyday violence," which both normalizes and legitimizes police power and structural violence. Alongside the urgent need for decriminalization of sex work and STI prevention programs tailored for this complex population, prompt investigation and harsher penalties for police officers who engage in sex with FSW could help shift police culture away from abuse.

HIV viral load trajectories of women living with HIV in Metro Vancouver, Canada

This study describes long-term viral load (VL) trajectories and their predictors among women living with HIV (WLWH), using data from Sexual Health and HIV/AIDS: Women's Longitudinal Needs Assessment (SHAWNA), an open prospective cohort study with linkages to the HIV/AIDS Drug Treatment Program. Using Latent Class Growth Analysis (LCGA) on a sample of 153 WLWH (1088 observations), three distinct trajectories of detectable VL (≥50 copies/ml) were identified: 'sustained low probability of detectable VL', characterized by high probability of long-term VL undetectability (51% of participants); 'high probability of delayed viral undetectability', characterized by a high probability VL detectability at baseline that decreases over time (43% of participants); and 'high probability of detectable VL', characterized by a high probability of long-term VL detectability (7% of participants). In multivariable analysis, incarceration (adjusted odds ratio (AOR) = 3.24; 95%CI:1.34-7.82), younger age (AOR = 0.96; 95%CI:0.92-1.00), and lower CD4 count (AOR = 0.82; 95%CI:0.72-0.93) were associated with 'high probability of delayed viral undetectability' compared to 'sustained low probability of detectable VL.' This study reveals the dynamic and heterogeneous nature of WLWH's long-term VL patterns, and highlights the need for early engagement in HIV care among young WLWH and programs to mitigate the destabilizing impact of incarceration on WLWH's HIV treatment outcomes.

Patterns of Exposure to Socio-structural Stressors and HIV Care Engagement Among Transgender Women of Color

Transgender women are disproportionately affected by HIV and experiences of social adversity that may interfere with engagement in care and viral suppression. We used latent class analysis to examine patterns of social adversity and their impact on HIV care continuum outcomes in an urban sample of transgender women of color. Participants (n = 224) were median age 29 and 86% non-Hispanic Black. Lack of resources, unemployment, and housing instability were reported by over 50%, and 41% reported history of incarceration. Latent class analysis identified 2 distinct classes representing higher and lower levels of social adversity. In latent class regression, membership in the higher social adversity class was associated with statistically significantly lower odds of viral suppression and HIV care engagement in univariate analysis; when adjusted for age, race, and recruitment site the association remained statistically significant for viral suppression (aOR 0.38, 95% CI 0.18-0.79; chi-square = 6.681, d.f. = 1, p = 0.010), though not for HIV care engagement. Our findings highlight the impact of socio-structural barriers on engagement in the HIV care continuum among transgender women.

Exposure to Police and Client Violence Among Incarcerated Female Sex Workers in Baltimore City, Maryland

Objectives. To determine the rate and correlates of incarceration among street-based female sex workers (FSWs).Methods. From April 2016 to January 2017, FSWs (n = 250) in Baltimore City, Maryland, were enrolled in a 12-month prospective cohort study. We analyzed baseline data and used zero-inflated negative binomial regression to model the incarceration rate.Results. Overall, 70% of FSWs had ever been incarcerated (mean = 15 times). In the multivariable analysis, incarceration rate was higher for FSWs exposed to police violence, non-Hispanic White FSWs, and women who used injection drugs daily. Risk for ever being incarcerated was higher for FSWs exposed to police or client violence, non-Hispanic Black FSWs, women who used injection or noninjection drugs daily, and those with longer time in sex work.Conclusions. Incarceration was associated with exposure to violence from both police and clients. Daily drug use and time in sex work appeared to amplify these risks. Although non-Hispanic Black women were at greater risk for ever being incarcerated, non-Hispanic White women were incarcerated more frequently.Public Health Implications. Decriminalization of sex work and drug use should be prioritized to reduce violence against FSWs.

Structural vulnerabilities and HIV risk among sexual minority female sex workers (SM-FSW) by identity and behavior in Baltimore, MD

BACKGROUND

Research suggests sexual minority female sex workers (SM-FSW) face elevated structural vulnerability and HIV risk compared to their heterosexual counterparts. Structural vulnerabilities reflect societal level factors (e.g., sexism, homophobia, racism) that constrain an individual's agency, particularly related to health outcomes. This study examines the association between SM status by identity and behavior, structural vulnerability, and HIV risk among a sample of street-based FSW.

METHODS

The current study utilizes baseline data from the SAPPHIRE study, a prospective cohort of cis gender and transgender FSW in Baltimore, MD, recruited through targeted time-location sampling from April 2016 to January 2017. The current analysis focuses on cisgender women. The baseline survey ascertained demographics, substance use, intimate partner violence (IPV), and sex work characteristics. Multivariable models were constructed using self-identity and behaviorally defined SM status as independent variables with vulnerability outcomes (e.g., injection drug use, injection speedball, binge drinking, homelessness, physical IPV, ever had a pimp, and being a minor at sex work entry (age < 18)) as dependent variables.

RESULTS

Of the participants (n = 247), 25.5% (n = 63) self-identified as a SM by identity (e.g., gay or bisexual), and 8.5% (n = 21) reported SM behavior (e.g., same-gender sexual behavior) in the past 3 months. In multivariable logistic regression models, SM status by identity was associated with increased odds of injection drug use, binge drinking, homelessness, physical IPV, and being a minor at sex work entry. SM status by behavior was associated with increased odds of binge drinking, homelessness, ever having a pimp, and being a minor at sex work entry.

CONCLUSION

The study indicates disproportionate structural vulnerability and heightened HIV risk among SM-FSW, as compared to their heterosexual counterparts, with differences in their profile by sexual identity and behavior. Findings suggest a need for nuanced interventions tailored to these populations.

Creating HIV risk profiles for men in South Africa: a latent class approach using cross-sectional survey data

INTRODUCTION

Engaging at-risk men in HIV prevention programs and services is a current priority, yet there are few effective ways to identify which men are at highest risk or how to best reach them. In this study we generated multi-factor profiles of HIV acquisition/transmission risk for men in Durban, South Africa, to help inform targeted programming and service delivery.

METHODS

Data come from surveys with 947 men ages 20 to 40 conducted in two informal settlements from May to September 2017. Using latent class analysis (LCA), which detects a small set of underlying groups based on multiple dimensions, we identified classes based on nine HIV risk factors and socio-demographic characteristics. We then compared HIV service use between the classes.

RESULTS

We identified four latent classes, with good model fit statistics. The older high-risk class (20% of the sample; mean age 36) were more likely married/cohabiting and employed, with multiple sexual partners, substantial age-disparity with partners (eight years younger on-average), transactional relationships (including more resource-intensive forms like paying for partner's rent), and hazardous drinking. The younger high-risk class (24%; mean age 27) were likely unmarried and employed, with the highest probability of multiple partners in the last year (including 42% with 5+ partners), transactional relationships (less resource-intensive, e.g., clothes/transportation), hazardous drinking, and inequitable gender views. The younger moderate-risk class (36%; mean age 23) were most likely unmarried, unemployed technical college/university students/graduates. They had a relatively high probability of multiple partners and transactional relationships (less resource-intensive), and moderate hazardous drinking. Finally, the older low-risk class (20%; mean age 29) were more likely married/cohabiting, employed, and highly gender-equitable, with few partners and limited transactional relationships. Circumcision (status) was higher among the younger moderate-risk class than either high-risk class (p < 0.001). HIV testing and treatment literacy score were suboptimal and did not differ across classes.

CONCLUSIONS

Distinct HIV risk profiles among men were identified. Interventions should focus on reaching the highest-risk profiles who, despite their elevated risk, were less or no more likely than the lower-risk to use HIV services. By enabling a more synergistic understanding of subgroups, LCA has potential to enable more strategic, data-driven programming and evaluation.

Barriers and facilitators to retaining a cohort of street-based cisgender female sex workers recruited in Baltimore, Maryland, USA: results from the SAPPHIRE study

BACKGROUND

Despite experiencing HIV/STIs, violence, and other morbidities at higher rates than the general public, street-based female sex workers are often absent from public health research and surveillance due to the difficulty and high costs associated with engagement and retention. The current study builds on existing literature by examining barriers and facilitators of retaining a street-based cohort of cisgender female sex workers recruited in a mobile setting in Baltimore, Maryland who participated in the SAPPHIRE study. Participants completed interviews and sexual health testing at baseline, 3-, 6-, 9-, and 12-months.

METHODS

Retention strategies are described and discussed in light of their benefits and challenges. Strategies included collecting several forms of participant contact information, maintaining an extensive field presence by data collectors, conducting social media outreach and public record searches, and providing cash and non-cash incentives. We also calculated raw and adjusted retention proportions at each follow-up period. Lastly, baseline sample characteristics were compared by number of completed visits across demographic, structural vulnerabilities, work environment, and substance use variables using F-tests and Pearson's chi-square tests.

RESULTS

Although there were drawbacks to each retention strategy, each method was useful in tandem in achieving a successful follow-up rate. While direct forms of contact such as phone calls, social media outreach, and email were useful for retaining more stable participants, less stable participants required extensive field-based efforts such as home and site visits that increase the likelihood of random encounters. Overall, adjusted retention exceeded 70% for the duration of the 12-month study. Participants who were younger, recently experienced homelessness, and injected drugs daily were less likely to have completed all or most follow-up visits.

CONCLUSION

Retention of street-based female sex workers required the simultaneous use of diverse retention strategies that were tailored to participant characteristics. With familiarity of the dynamic nature of the study population characteristics, resources can be appropriately allocated to strategies most likely to result in successful retention.

Patterns and Correlates of New Drug Initiation among Female Exotic Dancers: The Contribution of Occupational and Structural Risks

Introduction: Exotic dance clubs (EDCs) can play pivotal roles in the production of drug-related risks for female exotic dancers (FED). We aimed to characterize the structural and occupational factors associated with new drug initiation post-EDC entry among new FED (N = 117) in Baltimore, Maryland. Materials and Methods: Logistic regression models tested the associations of new drug uptake, measured as initiating any illicit drug (including non-prescribed and diverted prescription narcotics) not used prior to EDC employment, with structural (e.g. debt sources, housing instability) and occupational (e.g. sex work, dancing as sole income source) vulnerabilities. Results: Most FED were younger than 24 years-old (60%), identified as Black/African American (61%), and did not complete high school (56%). Twenty-nine (25%) reported using any new drug post-EDC entry, with cocaine (34%) cited most frequently among newly initiated substances. In multivariable analysis, drug initiation was significantly associated with cumulative debt sources (Adjusted Odds Ratio [AOR] = 1.82, 95% Confidence Interval [CI]: 1.19-2.77), dancing as only income source (AOR = 4.21, CI: 1.29-13.71), and sex work (AOR = 9.26, CI: 2.74-31.32). Conclusions: Our findings implicate co-occurring structural and occupational factors in FED's initiation of illicit drugs proceeding EDC employment. Results demonstrate the coping role of drug use for FED in stressful working environments and the multiple vulnerabilities associated with illicit drug uptake. The study reinforces a need for harm reduction interventions (i.e. debt relief, employment connections, increased hourly pay) that consider the contribution of overlapping financial insecurities to the production of occupational risks motivating drug uptake.

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

Despite established links between food insecurity and HIV outcomes, no studies have examined the role of food insecurity among female sex workers (FSW) in the United States (US). The aim of this exploratory study was to identify correlates (structural vulnerability and health factors) of severe food insecurity among street-based FSW in Baltimore, Maryland using multivariable logistic regression. In adjusted models, FSW with severe food insecurity were at greater odds of recent homelessness, physical intimate partner violence, client condom refusal, and HIV infection. Multi-sectoral approaches must take into consideration the co-occurrence of structural and health vulnerabilities to food insecurity among FSW in the US, including those that address violence, housing, and HIV.

Relationship and communication characteristics associated with agreement between heart failure patients and their Carepartners on patient depressive symptoms

Objectives: Informal caregivers who recognize patients' depressive symptoms can better support self-care and encourage patients to seek treatment. We examined patient-caregiver agreement among patients with heart failure (HF). Our objectives were to (1) identify distinct groups of HF patients and their out-of-home informal caregivers (CarePartners) based on their relationship and communication characteristics, and (2) compare how these groups agree on the patients' depressive symptoms. Method: We used baseline data from a comparative effectiveness trial of a self-care support program for veterans with HF treated in outpatient clinics from 2009-2012. We used a cross-sectional design and latent class analysis (LCA) approach to identify distinct groups of patient-CarePartner dyads (n = 201) based on relationship and communication characteristics then evaluated agreement on patients' depressive symptoms within these groups. Results: The LCA analysis identified four groups: Collaborative (n = 102 dyads, 51%), Avoidant (n = 33 dyads, 16%), Distant (n = 35 dyads, 17%), and Antagonistic (n = 31 dyads, 15%). Dyadic agreement on the patients' depressive symptoms was highest in the Distant (Kappa (κ) = 0.44, r = 0.39) and Collaborative groups (κ = 0.19, r = 0.32), and relatively poor in the Avoidant (κ = -0.20, r = 0.17) and Antagonistic (κ =-0.01, r = 0.004) groups. Patients in Avoidant (61%) and Antagonistic groups (74%) more frequently had depression based on self-report than patients in Collaborative (46%) and Distant (34%) groups. Conclusion: Caregiver relationships in HF tend to be either Collaborative, Avoidant, Distant, or Antagonistic. Patients' depressive symptoms may negatively affect how they communicate with their caregivers. At the same time, improved patient-caregiver communication could enhance dyadic consensus about the patient's depressive symptoms.

Are Opportunities Being Missed? Burden of HIV, STI and TB, and Unawareness of HIV among African Migrants

Sub-Saharan African migrants (SSAMs) have been disproportionately affected by infectious disease burden. We aimed to identify correlates of HIV, past sexually transmitted infection (STI) and past Tuberculosis infection (TB), as well as examine HIV seropositivity unawareness and testing history among SSAMs. A venue-based sample of 790 SSAMs completed a cross-sectional biobehavioral survey on sexual practices, HIV testing and self-reported infectious diseases; an HIV rapid test was offered. Overall, 5.4% of participants were HIV-positive and 16.7% reported a past STI. Odds of being HIV positive or having a past STI were higher among participants with low socioeconomic status and who experienced violence from a partner. Increased odds of having a past STI were also found among long-term migrants and those who reported sexual risk behaviors. In total, 4.1% of participants had TB in the past; these were more likely male and HIV positive. Unawareness of HIV-positive status was notably high (35%). Half of the participants had never been tested for HIV before, including over a third of those who had STI or TB in the past. Efforts are needed to reduce missed opportunities for HIV/STIs prevention and uptake of HIV testing among SSAMs through more integrated care, while addressing social determinants of infectious diseases.

Interpersonal and structural factors associated with receptive syringe-sharing among a prospective cohort of female sex workers who inject drugs

AIMS

To determine the interpersonal and structural factors associated with receptive syringe sharing (RSS) among female sex workers who inject drugs (FSW-IDU), a group at high risk of HIV/hepatitis C virus (HCV) acquisition.

DESIGN

Sex workers And Police Promoting Health In Risky Environments (SAPPHIRE) study, a prospective cohort study.

SETTING

Baltimore, MD, USA PARTICIPANTS: One hundred and eighty FSW-IDU; mean age = 33 years, 77.1% white and 62.9% in a relationship/married.

MEASUREMENTS

Surveys were conducted between April 2016 and February 2018. The main outcome was recent RSS (past 3 months). In addition to socio-demographic characteristics and drug use behaviors, we assessed factors at the interpersonal level, including injection practices, intimate partner and client drug use and exposure to violence. Structural-level factors included methods of syringe access.

FINDINGS

Nearly all FSW-IDU used heroin (97.1%) or crack cocaine (89.7%). Recent RSS was reported by 18.3%. Syringes were accessed from needle exchange programs (64.6%), pharmacies (29.7%), street sellers (30.3%) or personal networks (29.1%). Some FSW-IDU had clients or intimate partners who injected drugs (26.3 and 26.9%, respectively). Longitudinal factors independently associated with RSS in the multi-level mixed-effects model were recent client violence [adjusted odds ratio (aOR) = 2.17, 95% confidence interval (CI) = 1.09-4.33], having an intimate partner who injected drugs (aOR = 2.18, 95% CI = 0.98-4.85), being injected by others (aOR = 4.95, 95% CI = 2.42-10.10) and obtaining syringes from a street seller (aOR = 1.88, 95% CI = 0.94-3.78) or from a member of their personal network (aOR = 4.43, 95% CI = 2.21-8.90).

CONCLUSIONS

Client violence, intimate partner injection drug use, being injected by others and obtaining syringes from personal connections appear to increase parenteral HIV/HCV risk among female sex workers who inject drugs.

CAM Practices and Treatment Adherence Among Key Subpopulations of HIV+ Latinos Receiving Care in the San Diego-Tijuana Border Region: A Latent Class Analysis

Latinos living in the United States-Mexico border region bear a disproportionate HIV/AIDS burden compared to individuals living in the interior of both nations and face a constellation of barriers that determine their ability to access and adhere to HIV care. Use of complementary and alternative medicine (CAM) may be associated with suboptimal treatment adherence. Sociodemographic factors, health practices, and social determinants of health unique to the border region may further contribute to health disparities that undermine care engagement and continuity. Improved understanding of HIV-positive Latino subgroups and their risk profiles can lead to more effective, targeted clinical and public health interventions. We undertook this study to identify and characterize distinct classes of HIV-positive Latinos in the San Diego-Tijuana border region, differentiated by HIV and border-related factors, utilizing latent class analysis. We investigated relationships between class membership and CAM utilization and self-reported antiretroviral therapy (ART) adherence. Five distinct classes were identified with unique demographic, HIV risk, and border mobility profiles. CAM was recently used by nearly half of each class, though there were significant differences in the proportion of CAM use by class ranging from 44.4 to 90.9%. As well, all classes were currently receiving ART at similarly high rates and ART adherence outcomes were not significantly different based on class. Findings highlight the significant use of CAM by all HIV-positive Latinos in the border region and imply the need for a research framework which appropriately acknowledges the heterogeneous nature of this population, such as intersectionality. Further research is recommended into understanding how patients integrate CAM into HIV treatment and the risks and benefits of incorporating CAM into HIV treatment.

Drivers of HIV Infection Among Cisgender and Transgender Female Sex Worker Populations in Baltimore City: Results From the SAPPHIRE Study

OBJECTIVE

To determine and compare risk factors for HIV infection among cisgender female sex workers (CFSWs) and transgender female sex workers (TFSWs).

DESIGN

Baseline data from a cohort study (SAPPHIRE) of street-based CFSW and TFSW in Baltimore, MD.

METHODS

Women were queried about individual (eg, drug use), interpersonal (eg, sexual abuse), and structural (eg, housing) risk factors and questioned on their sex work risk environment. Women were tested for HIV/sexually transmitted infections. We used logistic regression to identify key risk factors for prevalent HIV in each population.

RESULTS

We recruited 262 CFSW and 62 TFSW between 2016 and 2017. Compared with TFSW, CFSW were more likely to be white (66% vs. 0%), recently homeless (62% vs. 23%, P < 0.001), regularly gone to sleep hungry (54% vs. 16%, P < 0.001), and to inject drugs (71% vs. 4%, P < 0.001). HIV prevalence was 8 times greater in TFSW than in CFSW (40% vs. 5%, P < 0.001). All participants reported high rates of lifetime physical and sexual violence. Cocaine injection [adjusted odds ratio (aOR) = 3.65, 95% confidence interval (CI): 1.12 to 11.88], food insecurity (aOR = 1.92, 95% CI: 1.22 to 3.04), and >5 years in sex work (aOR = 5.40, 95% CI: 2.10 to 13.90) were independently associated with HIV among CFSW. Childhood sexual abuse (aOR = 4.56, 95% CI: 1.20 to 17.32), being in sex work due to lack of opportunities (aOR = 4.81, 95% CI: 1.29 to 17.90), and >5 years in sex work (aOR = 5.62, 95% CI: 1.44 to 21.85) were independently associated with HIV among TFSW.

CONCLUSIONS

Although distinct, both populations share a history of extensive childhood abuse and later life structural vulnerability, which drive their engagement in street-based sex work and their HIV risk profiles.

Police-Related Correlates of Client-Perpetrated Violence Among Female Sex Workers in Baltimore City, Maryland

OBJECTIVES

To characterize interactions that female sex workers (FSWs) have with the police and explore associations with client-perpetrated violence.

METHODS

Baseline data were collected April 2016 to January 2017 from 250 FSWs from the Sex Workers and Police Promoting Health in Risky Environments (SAPPHIRE) study based in Baltimore, Maryland. Interviewer-administered questionnaires captured different patrol or enforcement and abusive police encounters, experiences of client-perpetrated violence, and other risk factors, including drug use. We conducted bivariate and multivariable analysis in Stata/SE version 14.2 (StataCorp LP, College Station, TX).

RESULTS

Of participants, 78% reported lifetime abusive police encounters, 41% reported daily or weekly encounters of any type. In the previous 3 months, 22% experienced client-perpetrated violence. Heroin users (70% of participants) reported more abusive encounters (2.5 vs 1.6; P < .001) and more client-perpetrated violence (26% vs 12%; P = .02) than others. In multivariable analysis, each additional type of abusive interaction was associated with 1.3 times (95% confidence interval [CI] = 1.1, 1.5) increased odds of client-perpetrated violence. For patrol or enforcement encounters, this value was 1.3 (95% CI = 1.0, 1.7).

CONCLUSIONS

Frequent exposures to abusive police practices appear to contribute to an environment where client-perpetrated violence is regularly experienced. For FSWs who inject drugs, police exposure and client-perpetrated violence appear amplified. Public Health Implications. Structural interventions that address police-FSW interactions will help alleviate police's negative impact on FSWs' work environment.

Patterns of primary healthcare use among female exotic dancers in Baltimore, Maryland

Female exotic dancers (FEDs) are often exposed to violence-, sex- and drug-related occupational harms and are precluded from employer-based health insurance. We examined access to primary health-care resources, correlates of use, and service needs among a sample of new FEDs (N = 117) working in 22 exotic dance clubs (EDCs) in Baltimore, MD. Self-administered surveys were completed between May and October 2014. Health care measures were aggregated and described, and correlates of use were evaluated using Fisher Exact and Poisson regression with robust variance, adjusting for race/ethnicity. The majority of dancers reported having health insurance (80%), a primary care provider (PCP) (68%), and having visited a PCP (74%). Among dancers with insurance, all were covered by Medicaid. Multivariable regression models demonstrated that having a regular PCP was associated with recent PCP use (adjusted prevalence ratio 1.5; 95% confidence interval: 1.1, 2.1). Despite a high level of health-care coverage and recent visits to PCP, dancers frequently sought services at the emergency department and reported needs for medical care, including mental health support services and drug treatment. Findings highlight that basic access to primary health care is available and used but may not be fully meeting dancers' complex needs.

Correlates of exchange sex among a population-based sample of low-income women who have heterosexual sex in Baltimore

Sex exchange is associated with HIV and other morbidities yet has received little research, surveillance, and programmatic attention in the U.S. This study identified correlates of exchange sex and among low-income women in Baltimore, Maryland. Participants were recruited into the National HIV Behavioral Surveillance (NHBS) system in 2013 using respondent driven sampling (RDS) and completed a survey and HIV testing. The analytic sample (n = 253) consisted of women aged ≥18 years who had recent (past year) heterosexual sex. Multivariable logistic regression identified correlates of recent exchange sex. Independently associated with recent exchange sex were history of injection drug use (adjusted odds ratio (AOR) = 3.4, 95% CI: 1.1-10.3), recent prescription painkiller use (AOR = 3.7, 95% CI: 1.4-9.9), recent crack/cocaine use (AOR = 6.6, 95% CI: 2.1-20.9), recent arrest (AOR = 4.1, 95% CI: 1.2-14.8), and recent consistent condom use (AOR 1.1; 95% CI: 1.0-1.3). Women who exchanged sex exhibited heightened social and structural vulnerability and substance use. These data demonstrate the need for further research examining the context of exchange sex among low-income women and synergies between substance use and HIV risk.

Syndemic Risk Classes and Substance Use Problems among Adults in High-Risk Urban Areas: A Latent Class Analysis

Substance use problems tend to co-occur with risk factors that are especially prevalent in urban communities with high rates of poverty. The present study draws on Syndemics Theory to understand profiles of risk and resilience and their associations with substance use problems in a population at risk for adverse outcomes. African-American/Black and Hispanic heterosexual adults (N = 2,853) were recruited by respondent-driven sampling from an urban area with elevated poverty rates, and completed a structured assessment battery covering sociodemographics, syndemic factors (that is, multiple, co-occurring risk factors), and substance use. More than one-third of participants (36%) met criteria for either an alcohol or a drug problem in the past year. Latent class analysis identified profiles of risk and resilience, separately for women and men, which were associated with the probability of a substance use problem. Almost a third of women (27%) and 38% of men had lower risk profiles-patterns of resilience not apparent in other types of analyses. Profiles with more risk and fewer resilience factors were associated with an increased probability of substance use problems, but profiles with fewer risk and more resilience factors had rates of substance use problems that were very similar to the general adult population. Relative to the lowest risk profile, profiles with the most risk and fewest resilience factors were associated with increased odds of a substance use problem for both women [adjusted odds ratio (aOR) = 8.50; 95% CI: 3.85-18.74] and men (aOR = 11.68; 95% CI: 6.91-19.74). Addressing syndemic factors in substance use treatment and prevention may yield improved outcomes.
