Geographic disparities in late HIV diagnoses in Tennessee: Opportunities for interventions in the rural Southeast.

PURPOSE: Incident HIV remains an important public health issue in the US South, the region leading the nation in HIV incidence, rural HIV cases, and HIV-related deaths. Late diagnoses drive incident HIV and understanding factors driving late diagnoses is critical for developing locally relevant HIV testing and prevention interventions, decreasing HIV transmission, and ending the HIV epidemic. METHODS: Retrospective cohort study utilizing Tennessee Department of Health (TDH) surveillance data and US Census Bureau data. Adults of ≥18-year old with a new HIV diagnosis between January 1, 2015 and December 31, 2019 identified in the TDH electronic HIV/AIDS Reporting System were included. Individuals were followed from initial HIV diagnosis until death, 90 days of follow-up for outcome assessment, or administrative censoring 90 days after study enrollment closed. FINDINGS: We included 3652 newly HIV-diagnosed individuals; median age was 31 years (IQR: 25, 42), 2909 (79.7%) were male, 2057 (56.3%) were Black, 246 (6.7%) were Hispanic, 408 (11.2%) were residing in majority-rural areas at diagnosis, and 642 (17.6%) individuals received a late HIV diagnosis. Residents of majority-rural counties (adjusted risk ratios [aRR] = 1.39, 95% confidence intervals [CI]: 1.16-1.67) and Hispanic individuals (aRR = 1.87, 95% CI: 1.50-2.33) had an increased likelihood of receiving a late diagnosis after controlling for race/ethnicity, age, and year of HIV diagnosis. CONCLUSIONS: Rural residence and Hispanic ethnicity were associated with an increased risk of receiving a late HIV diagnosis in Tennessee. Future HIV testing and prevention efforts should be adapted to the needs of these vulnerable populations.

Characterizing residential mobility among people with HIV in Tennessee and its impact on HIV care outcomes.

OBJECTIVE: Our objective was to assess the prevalence and patterns of mobility among people with HIV (PWH) in Tennessee and its impact on HIV care outcomes. DESIGN: Retrospective cohort study. METHODS: We combined residential address and HIV surveillance data from PWH in Tennessee from 2016 to 2018. Using Poisson regression, we estimated associations between in-state mobility (change in address or total miles moved) in 1 year and outcomes in the subsequent year; retention: having two CD4 + /HIV RNA values (labs) in a calendar year at least 3 months apart, loss to follow-up (LTFU): having labs at baseline but not the subsequent year, and viral suppression: HIV RNA less than 200 copies/ml. We applied a kernel density estimator to origin-destination address lines to visualize mobility patterns across demographic subgroups. RESULTS: Among 17 428 PWH [median age 45 years (interquartile range; IQR 34-53)], 6564 (38%) had at least one move. Median miles moved was 8.9 (IQR 2.6-143.4)). We observed in-state movement between major cities (Chattanooga, Knoxville, Memphis and Nashville) and out-of-state movement to and from Georgia and Florida. Having at least one in-state move was associated with a decreased likelihood of retention [adjusted relative risk (aRR) = 0.91; 95% confidence interval (CI) 0.88-0.95], and an increased risk of LTFU (aRR = 1.17; 95% CI 1.04-1.31, two to three moves vs. none). Greater distance moved in-state was associated with decreased retention and increased LTFU (aRR = 0.53; 95% CI 0.49-0.58, aRR = 2.52; 95% CI 2.25-2.83, respectively for 1000 vs. 0 miles). There was no association between mobility and viral suppression. CONCLUSION: Mobility is common among PWH in Tennessee and is associated with initial poor engagement in HIV care.

Misclassification of Loss to Care Among Persons With Human Immunodeficiency Virus: Improved Capture of Silent Transfers Through Surveillance Linkage Using Statewide Mandatorily Reported Laboratory Measures.

Human Immunodeficiency Virus (HIV)-positive individuals lost to follow-up from particular clinics may not be lost to care (LTC). After linking Vanderbilt's Comprehensive Care Clinic cohort to Tennessee's statewide HIV surveillance database, LTC decreased from 48.4% to 35.0% at 10 years. Routine surveillance linkage by domestic HIV clinics would improve LTC and retention measure accuracy.

HIV and Hepatitis C Among People Who Inject Drugs in Memphis, Tennessee: an Intersectional Risk Environment Analysis of the Social Determinants of Health.

BACKGROUND: The Southern US is confronting bourgeoning HIV and hepatitis C virus (HCV) epidemics among people who inject drugs (PWID), yet little is known about shared and unique risk factors across the region. We applied an intersectional risk environment framework to understand infectious disease outcomes for sub-groups of PWID that experience multiple axes of social marginalization related to racial and ethnic identity and social and economic vulnerability. METHODS: HIV and HCV prevalence was estimated from the first iteration of the CDC's National HIV Behavioral Surveillance respondent driven sample of PWID in Shelby County, Tennessee in 2018. We ran adjusted multinomial models to test main and interaction effects of race/ethnicity and structural factors on the prevalence of a three-level outcome: HIV-only, HCV-only, and no infection. RESULTS: A total of 564 PWID participated, 558 (99%) completed HIV testing, and 540 (96%) HCV testing. Thirty (5%) were HIV-positive, 224 (40%) HCV-positive, and less than 1% were co-infected. Descriptive differences by race/ethnicity and levels of structural vulnerability for HIV and HCV subpopulations were present; however, there was no evidence for statistical interaction. In the final main effects model, HIV status was positively associated with non-Hispanic Black identity (aRR 4.95, 95% CI 1.19, 20.6), whereas HCV status was associated with non-white identity (aRR 0.11 95% CI 0.07, 0.18). Factors associated with HCV infection were higher scores of structural vulnerability (aRR 2.19 95% CI 1.10, 4.35), and criminal legal involvement (aOR 1.99 95% CI 1.18, 3.37). CONCLUSION: This is the first study to implement local population-based survey data to evaluate distinctive intersections of ethnic/racial and social factors associated with HIV and HCV status among PWID in the Memphis region. Findings come at an opportune time as harm reduction programs are in development in the South and shed light to the need for socially equitable race conscious resource investment.

Type of Exchange Sex and Associated Behaviors and Outcomes Among Cisgender Men and Women at Increased Risk for HIV via Heterosexual Transmission in Six U.S. Metropolitan Areas.

Exchange sex is associated with sexual risk behaviors and poor outcomes and different types may incur different levels of risk. We assessed risk profiles of different types of exchange sex among non-injecting cisgender men and women who participated in the 2019 National HIV Behavioral Surveillance project at six sites. Six percent of men and 19% of women reported exchange sex in the past year; most engaged in non-commercial exchange sex for drugs/money with smaller percentages reporting formal sex work or non-commercial exchange sex for goods or services other than drugs/money. Exchange sex was associated with sexual risk and prevention behaviors and psychosocial and sexual health outcomes and associations varied by type of exchange sex. Efforts to improve access to STI/HIV testing and PrEP may benefit from tailoring based on type of exchange sex. Findings indicate value in a broader definition of exchange sex with follow-up assessment of exchange sex typology.

Violence, Discrimination, Psychological Distress, and HIV Vulnerability Among Men Who Have Sex With Men in Memphis, Tennessee.

Gay, bisexual, and other men who have sex with men (MSM) are disproportionally impacted by HIV. Discrimination, violence, and psychological distress (PD) may influence engagement with HIV prevention services and amplify HIV vulnerability among this priority population. These dynamics are understudied in the Southern United States. Understanding how these relationships interact is critical to designing effective HIV programs. We examined associations between MSM-related discrimination, MSM-related violence, and severe PD with HIV status among 2017 National HIV Behavioral Surveillance study participants in Memphis, Tennessee. Eligible participants were aged ≥18 years, born and identified as male, and reported having sex with another man in their lifetime. Participants completed a Centers for Disease Control and Prevention-designed anonymous survey and self-reported discrimination and violence across their lifetime, and PD symptoms within the past month, scored on the Kessler-6 Scale. Optional HIV rapid tests were performed on-site. Logistic regressions examined the associations between the exposure variables and HIV antibody-positive results. Among 356 respondents, 66.9% were aged <35 years and 79.5% identified as non-Hispanic Black; 13.2% reported experiencing violence, 47.8% reported discrimination, and 10.7% experienced PD. Of the 297 participants who tested, 33.33% were living with HIV. Discrimination, violence, and PD were significantly associated with each other (p < .0001). HIV antibody-positive test results were associated with violence (p < .01). Memphis-based MSM face a complex array of social experiences, which may increase vulnerability to HIV. On-site testing at community-based organizations and clinical settings among MSM may be an opportunity to screen for violence and incorporate strategies when designing HIV programs.

Assessment of Tennessee's county-level vulnerability to hepatitis C virus and HIV outbreaks using socioeconomic, healthcare, and substance use indicators.

BACKGROUND: Human immunodeficiency virus (HIV), hepatitis C virus (HCV), and injection drug use are syndemic in the central Appalachian states. In Tennessee (TN), declines in HIV among persons who inject drugs (PWID) stalled, and HCV infection rates increased significantly from 2013-2017. To better target strategies to address the syndemic, county-level socioeconomic, opioid use, access to healthcare, and health factors were modeled to identify indicators predictive of vulnerability to an HIV/HCV outbreak among PWID in TN. METHODS: Newly reported chronic HCV cases among persons aged 13-39 years in 2016-2017 were used as a proxy for county-level HIV/HCV vulnerability among TN's 95 counties. Seventy-five publicly available county-level measures from 2016-2017 were collected and reduced through multiple dimension reduction techniques. Negative binomial regression identified indicators associated with HCV which were used to calculate county-level vulnerability to a local HIV/HCV outbreak. RESULTS: Thirteen county-level indicators were identified as strongly predictive of HIV/HCV vulnerability with the statistically significant indicators being percentage of the population aged 20-44 years, per capita income, teen birth rate, percentage of clients in TDMHSAS-funded opioid treatment and recovery, syphilis case rate, and percentage of homes with at least one vehicle. Based on the 13 indicators, we identified the distribution of vulnerability to an HIV/HCV outbreak among TN's counties. Eleven high vulnerability counties were identified, with the preponderance located in east and middle TN. CONCLUSION: This analysis identified the county-level factors most associated with vulnerability to an HIV/HCV outbreak among PWID in TN. These results, alongside routine surveillance, will guide targeted prevention and linkage to care efforts for the most vulnerable communities.

Comprehensive Process Mapping and Qualitative Interviews to Inform Implementation of Rapid Linkage to HIV Care Programs in a Mid-Sized Urban Setting in the Southern United States.

BACKGROUND: Rapid antiretroviral therapy (ART) initiation, in which people living with HIV start ART within days of diagnosis, is a key component of the US Ending the HIV Epidemic initiative. SETTING: The Memphis Metropolitan Statistical Area ranked fourth in the United States for the highest HIV incidence per 100,000 population in 2018. Rapid ART programs are limited in the Memphis Metropolitan Statistical Area, and our objective was to identify local implementation barriers. METHODS: We conducted participatory process mapping and in-depth interviews to detail steps between HIV testing at the municipal health department's Sexually Transmitted Infections Clinic and ART prescription from a nearby high-volume Ryan White-funded HIV Clinic. RESULTS: Process mapping identified 4 modifiable, rate-limiting rapid ART barriers: (1) requiring laboratory-based confirmatory HIV results, (2) eligibility documentation requirements for Ryan White-funded services, (3) insufficient HIV Clinic medical provider availability, and (4) variability in ART initiation timing among HIV Clinic providers. Staff at both sites highlighted suboptimal communication and sense of shared management between facilities, limited resources to address important social determinants of health, and lack of Medicaid expansion in Tennessee as key barriers. In-depth interview themes negatively affecting rapid ART initiation included clinic burden; provider knowledge, attitudes, and beliefs; and client psychosocial needs. CONCLUSIONS: Our preimplementation work identified modifiable and systemic barriers to systems flow and patient-level outcomes. This work will inform the design and implementation of a locally relevant rapid ART program in Memphis, a community disproportionately affected by the HIV epidemic.

Individual, community, and structural factors associated with linkage to HIV care among people diagnosed with HIV in Tennessee.

OBJECTIVE: We assessed trends and identified individual- and county-level factors associated with individual linkage to HIV care in Tennessee (TN). METHODS: TN residents diagnosed with HIV from 2012-2016 were included in the analysis (n = 3,751). Individuals were assigned county-level factors based on county of residence at the time of diagnosis. Linkage was defined by the first CD4 or HIV RNA test date after HIV diagnosis. We used modified Poisson regression to estimate probability of 30-day linkage to care at the individual-level and the contribution of individual and county-level factors to this outcome. RESULTS: Both MSM (aRR 1.23, 95%CI 0.98-1.55) and women who reported heterosexual sex risk factors (aRR 1.39, 95%CI 1.18-1.65) were more likely to link to care within 30-days than heterosexual males. Non-Hispanic Black individuals had poorer linkage than White individuals (aRR 0.77, 95%CI 0.71-0.83). County-level mentally unhealthy days were negatively associated with linkage (aRR 0.63, 95%CI: 0.40-0.99). CONCLUSIONS: Racial disparities in linkage to care persist at both individual and county levels, even when adjusting for county-level social determinants of health. These findings suggest a need for structural interventions to address both structural racism and mental health needs to improve linkage to care and minimize racial disparities in HIV outcomes.

'PrEP'ing Memphis: A qualitative process evaluation of peer navigation support.

BACKGROUND: HIV PrEP (pre-exposure prophylaxis) navigation comprises intervention strategies used to improve PrEP uptake via education, linkage, and follow-up/ongoing engagement. During 2016-2019, the Tennessee Department of Health (TDH) implemented a CDC-funded demonstration project ("Project PrIDE") focused on PrEP navigation in Memphis community-based organizations (CBOs) and the Shelby County Health Department (HD). A process evaluation was conducted to determine facilitators and barriers to the implementation of the Memphis-based Project PrIDE PrEP navigation activities. METHODS: A total of fourteen in-depth qualitative interviews were conducted, with nine PrEP navigators in evaluation year 1 (2018) and five of the original navigators in evaluation year 2 (2019), to understand the navigation processes using thematic analysis. RESULTS: Facilitators of PrEP navigation included accessing clients at testing events, accompanying clients to first appointments, rapport building with patient and clinic staff, and maintaining consistent engagement with clients. Factors impeding PrEP navigation included difficulties assessing client readiness, tracking client navigation status, and stigmatizing clinic and social experiences for clients. CONCLUSIONS AND LESSONS LEARNED: Findings have informed the scale-up of PrEP navigation implementation statewide, along with priority setting and resource allocation for the local Ending the HIV Epidemic (EHE) initiative in Memphis.

Who Is Not Linking to HIV Care in Tennessee - the Benefits of an Intersectional Approach.

INTRODUCTION: Guided by an intersectional approach, we assessed the association between social categories (individual and combined) on time to linkage to HIV care in Tennessee. METHODS: Tennessee residents diagnosed with HIV from 2012-2016 were included in the analysis (n=3750). Linkage was defined by the first CD4 or HIV RNA test date after HIV diagnosis. We used Cox proportional hazards models to assess the association of time to linkage with individual-level variables. We modeled interactions between race, age, gender, and HIV acquisition risk factor (RF), to understand how these variables jointly influence linkage to care. RESULTS: Age, race, and gender/RF weAima A. Ahonkhaire strong individual (p < 0.001 for each) and joint predictors of time to linkage to HIV care (p < 0.001 for interaction). Older individuals were more likely to link to care (aHR comparing 40 vs. 30 years, 1.20, 95%CI 1.11-1.29). Blacks were less likely to link to care than Whites (aHR= 0.73, 95% CI: 0.67-0.79). Men who have sex with men (MSM) (aHR = 1.18, 95%CI: 1.03-1.34) and heterosexually active females (females) (aHR = 1.32, 95%CI: 1.14-1.53) were more likely to link to care than heterosexually active males. The three-way interaction between age, race, and gender/RF showed that Black males overall and young, heterosexually active Black males in particular were least likely to establish care. CONCLUSIONS: Racial disparities persist in establishing HIV care in Tennessee, but data highlighting the combined influence of age, race, gender, and sexual orientation suggest that heterosexually active Black males should be an important focus of targeted interventions for linkage to HIV care.

Informing the future of PrEP navigation: Findings from a five-site cluster evaluation.

The PrEP (pre-exposure prophylaxis) Implementation, Data to Care and Evaluation (PrIDE) demonstration project funded 12 health departments (HD) (2016-2019) to scale up PrEP among sexual minorities at risk for HIV. Each health department (HD) conducted an evaluation of at least one local strategy, and, to maximize crossvalidation, an adapted cluster evaluation approach was employed. As a result, five HDs with similar evaluation questions regarding PrEP navigation were identified. Overall, PrEP navigation fit in well with HD clinics and community-based organizations. A hybrid model of patient, peer, and systems navigation linking clients to PrEP and social services was commonly used. Although there were no differences by setting regarding linking clients to PrEP providers, one HD demonstrated that having all PrEP services in the same location contributed the most to PrEP uptake. Navigator skill for case management and rapport building facilitated navigation, whereas staff turnover and lack of client health insurance were challenges. While one HD in a non-Medicaid expansion state was affected by health insurance issues the most, another HD demonstrated that providing payment assistance increased client PrEP use. The findings pinpoint PrEP navigation hybrid modality and having health insurance as promising strategies to increase PrEP uptake among priority groups.

Risk of HIV Diagnosis Following Bacterial Sexually Transmitted Infections in Tennessee, 2013-2017.

BACKGROUND: Data on associations between sexually transmitted infections (STIs) and incident human immunodeficiency virus (HIV) diagnoses beyond men who have sex with men (MSM) are lacking. Identifying STIs associated with greatest risk of incident HIV diagnosis could help better target HIV testing and prevention interventions. METHODS: The STI and HIV surveillance data from individuals 13 years or older in Tennessee from January 2013 to December 2017 were cross-matched. Individuals without diagnosed HIV, but with reportable STIs (chlamydia, gonorrhea, syphilis) were followed up from first STI diagnosis until HIV diagnosis or end of study. Cox regression with time-varying STI exposure was used to estimate adjusted hazard ratios (aHRs) and 95% confidence intervals (CI) for subsequent HIV diagnosis; results were stratified by self-reported MSM. RESULTS: We included 148,465 individuals without HIV (3831 MSM; 144,634 non-MSM, including heterosexual men and women) diagnosed with reportable STIs; 473 had incident HIV diagnoses over 377,823 person-years (p-y) of follow-up (median, 2.6 p-y). Controlling for demographic and behavioral factors, diagnoses of gonorrhea, early syphilis, late syphilis, and STI coinfection were independently associated with incident HIV diagnosis compared with chlamydia. Early syphilis was associated with highest HIV diagnosis risk overall (aHR, 5.5; 95% CI, 3.5-5.8); this risk was higher for non-MSM (aHR, 12.3; 95% CI, 6.8-22.3) versus MSM (aHR, 2.9; 95% CI, 1.7-4.7). CONCLUSIONS: While public health efforts often focus on MSM, non-MSM with STIs is also a subgroup at high risk of incident HIV diagnosis. Non-MSM and MSM with any STI, particularly syphilis, should be prioritized for HIV testing and prevention interventions.

Using an Established Outbreak Response Plan and Molecular Epidemiology Methods in an HIV Transmission Cluster Investigation, Tennessee, January-June 2017.

INTRODUCTION: In April 2017, the Tennessee Department of Health (TDH) was notified of an increase in the number of persons newly diagnosed with HIV in eastern Tennessee in the same month. Two were identified as persons with a history of injection drug use (IDU) and named each other as syringe-sharing partners, prompting an investigation into a possible HIV cluster among persons with a history of IDU. MATERIALS AND METHODS: TDH and public health staff members in eastern Tennessee collaborated to implement procedures outlined in TDH's HIV/hepatitis C virus (HCV) Outbreak Response Plan, including conducting enhanced interviewing and using a preestablished database for data collection and management. To complement contact tracing and enhanced interviewing, TDH partnered with the Centers for Disease Control and Prevention to conduct molecular HIV analyses. RESULTS: By June 27, 2017, the investigation had identified 31 persons newly diagnosed with HIV infection; 8 (26%) self-reported IDU, 4 of whom were also men who have sex with men (MSM). Of the remaining 23 persons newly diagnosed with HIV infection, 10 were MSM who did not report IDU, 9 reported high-risk heterosexual contact, and 4 had other or unknown risk factors. Molecular analysis of the 14 HIV-1 polymerase genes (including 7 of the 8 persons self-reporting IDU) revealed 3 distinct molecular clusters, one of which included 3 persons self-reporting IDU. PRACTICE IMPLICATIONS: This investigation highlights the importance of implementing an established Outbreak Response Plan and using HIV molecular analyses in the event of a transmission cluster or outbreak investigations. Future HIV outbreak surveillance will include using Global Hepatitis Outbreak Surveillance Technology to identify HCV gene sequences as a potential harbinger for HIV transmission networks.

Temporal Trends and Sociodemographic Correlates of PrEP Uptake in Tennessee, 2017.

Client-level data from two Tennessee-based PrEP navigation demonstration projects reported to the Tennessee Department of Health from January to December 2017 were evaluated to determine the proportion of clients who accepted, were linked to, and were prescribed PrEP. Disparities by age, race, transmission risk, and geographic region as well as trends over time were examined via bivariate and multivariable modified Poisson regression models accounting for potential confounders. Among 1385 PrEP-eligible individuals, 50.5% accepted, 33.4% were linked, and 27.3% were prescribed PrEP. PrEP uptake varied by age, race, and HIV transmission risk, and most disparities persisted across Tennessee throughout evaluation period. Multivariable regression models revealed significant independent associations between age, race/ethnicity, transmission risk, and region and PrEP acceptance and linkage. While differences in PrEP acceptance by race narrowed over time, success among black MSM was limited, underscoring a significant need to improve upstream PrEP continuum outcomes for this important population.

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.

Structural risk and limits on agency among exotic dancers: HIV risk practices in the exotic dance club.

This paper provides longitudinal examination of women's health and sexual risk trajectories in US exotic dance clubs, which represent an important commercial setting for the economic mainstreaming of sexual services and an important target for public health programmes. Between July 2014 and May 2015, two semi-structured interviews (at baseline and at three months) were conducted with 24 female exotic dancers who had recently started working in in Baltimore City, USA. Results from a constant comparative analysis point to the interrelationship between the structures of the club setting, including the social context, and women's agentic practices concerning their sexual health. Study findings highlight the centrality of the interrelationship between individual- and structural-level experiences in influencing dancers' risk behavior. Findings point to the need for interventions to empower women both individually and collectively so as to provide the foundation for longer-term structural change.

Barriers and Facilitators to the Implementation of a National HIV Linkage, Re-Engagement, and Retention in Care Program.

The 2020 National HIV AIDS Strategy (NHAS) sets a target of 90% of diagnosed people living with HIV (PLWH) retained in HIV care. Access to Care (A2C) was a national HIV linkage, re-engagement, and retention in care program funded by AIDS United with support from the Corporation for National and Community Service that aimed to link and retain the most vulnerable PLWH into high-quality HIV care. This study explores the barriers and facilitators of implementing the A2C program from the perspective of program staff. Ninety-eight qualitative interviews were conducted with staff at implementing organizations over the 5 years of the project. Barriers included challenges with recruiting and retaining participants, staffing and administration, harmonizing partnerships, and addressing the basic and psychosocial needs of participants. Facilitators included strong relationships with partner organizations, flexible program models, and the passion and dedication of staff. Findings will inform the development of future programs and policy.

Experiences of structural vulnerability among exotic dancers in Baltimore, Maryland: Co-occurring social and economic antecedents of HIV/STI risk.

BACKGROUND: Women who grow up in economic scarcity often face limited opportunities for upward mobility, as a result of challenges securing stable housing, quality education, and steady employment. Chronic instability may limit the capacity of women to protect themselves against HIV/STI-related harm when engaging in sexual activity or drug use. Characterizing the structural contexts that facilitate HIV/STI risk among women are critical to effective design and implementation of drug and sexual harm reduction interventions. METHODS: Semi-structured in-depth interviews were completed with 25 female exotic dancers working in Baltimore City and County exotic dance clubs July 2014-May 2015. Using thematic analysis, interviews were examined to understand the nature of structural vulnerability experienced by dancers during their early lives through the initial months of exotic dancing, including an examination of the roles of drug use and social relationships in engagement of sexual risk behavior. RESULTS: Dancers depicted early experiences of social and economic disadvantage, which accumulated through early adulthood. Substance use emerged as an important subject for the majority of women, operating cyclically as both precursor to and product of accumulating social and economic hardship. Dancers revealed social strategies that buffered the effects of structural vulnerability and minimized exposure to workplace-related drug and sexual harms. CONCLUSION: This study provides insight on an understudied group of at-risk women with a unique demographic profile. Findings illustrate how the effects of structural vulnerability, substance abuse, social strategies, and opportunities for economic gain through sexual services in the workplace converge to produce varying levels of HIV/STI risk among exotic dancers.

The network structure of sex partner meeting places reported by HIV-infected MSM: Opportunities for HIV targeted control.

Baltimore, Maryland ranks among U.S. cities with the highest incidence of HIV infection among men who have sex with men (MSM). HIV screening at sex partner meeting places or venues frequented by MSM with new diagnoses and/or high HIV viral load may reduce transmission by identifying and linking infected individuals to care. We investigated venue-based clustering of newly diagnosed MSM to identify high HIV transmission venues. HIV surveillance data from MSM diagnosed between October 2012-June 2014 and reporting ≥1 sex partner meeting place were examined. Venue viral load was defined according to the geometric mean viral load of the cluster of cases that reported the venue and classified as high (>50,000 copies/mL), moderate (1500-50,000 copies/mL), and low (<1500 copies/mL). 143 MSM provided information on ≥1 sex partner meeting place, accounting for 132 unique venues. Twenty-six venues were reported by > 1 MSM; of these, a tightly connected cluster of six moderate viral load sex partner meeting places emerged, representing 66% of reports. Small, dense networks of moderate to high viral load venues may be important for targeted HIV control among MSM.
