Introduction/UNASSIGNED:Sikh Asian Indians are an underserved, minority group demonstrating high rates of diabetes. Community health workers (CHWs) are effective in addressing health disparities by reaching socially and linguistically isolated populations. There are no culturally-adapted programs for diabetes prevention among Sikh Asian Indians, thus, this study tests the efficacy of a culturally-tailored CHW intervention to improve diabetes prevention-related outcomes among Sikh Asian Indians at-risk for diabetes. Methods/UNASSIGNED:A quasi-experimental two-arm intervention among Sikh Asian Indian adults at-risk for diabetes and living in New York City (n=160) was conducted in 2013-2014. The treatment group received six monthly CHW group education sessions and ten follow-up phone calls; the control group received the first session. Main outcomes included weight, body mass index (BMI), blood pressure (BP), physical activity (PA), diet, and health self-efficacy. Results/UNASSIGNED:Positive and significant changes in weight, BMI, and diabetes prevention-related indicators were seen among both study groups. However, only treatment group participants showed significant changes over time for weight, BMI, PA self-efficacy, and health-related self-efficacy. Significant between-group differences were seen in adjusted analyses for weight, BMI, systolic BP, total weekly PA, PA self-efficacy, PA social interaction, portion control, barriers to healthy eating, and health self-efficacy. At 6-months, treatment participants were more likely to lose ≥5% and ≥7% of their weight compared to control participants (p=0.071, and p=0.015, respectively). Conclusions/UNASSIGNED:Findings demonstrate that a culturally-adapted CHW diabetes prevention program in the Sikh community is efficacious, adding to the growing literature on CHWs' capacity to address health inequity among underserved populations.

BACKGROUND:Electronic health record (EHR)-based interventions that use registries and alerts can improve chronic disease care in primary care settings. Community health worker (CHW) interventions also have been shown to improve chronic disease outcomes, especially in minority communities. Despite their potential, these two approaches have not been tested together, including in small primary care practice (PCP) settings. This paper presents the protocol of Diabetes Research, Education, and Action for Minorities (DREAM) Initiative, a 5-year randomized controlled trial integrating both EHR and CHW approaches into a network of PCPs in New York City (NYC) in order to support weight loss efforts among South Asian patients at risk for diabetes. METHODS/DESIGN/METHODS:The DREAM Initiative was funded by the National Institute of Diabetes and Digestive and Kidney Diseases (National Institutes of Health). A total of 480 individuals at risk for type 2 diabetes will be enrolled into the intervention group, and an equal number will be included in a matched control group. The EHR intervention components include the provision of technical assistance to participating PCPs regarding prediabetes-related registry reports, alerts, and order sets. The CHW intervention components entail group education sessions on diabetes prevention, including weight loss and nutrition. A mixed-methods approach will be used to evaluate the feasibility, adoption, and impact (≥ 5% weight loss) of the integrated study components. Additionally, a cost effectiveness analysis will be conducted using outcomes, implementation costs, and healthcare claims data to determine the incremental cost per person achieving 5% weight loss. DISCUSSION/CONCLUSIONS:This study will be the first to test the efficacy of an integrated EHR-CHW intervention within an underserved, minority population and in a practical setting via a network of small PCPs in NYC. The study's implementation is enhanced through cross-sector partnerships, including the local health department, a healthcare payer, and EHR vendors. Through use of a software platform, the study will also systematically track and monitor CHW referrals to social service organizations. Study findings, including those resulting from cost-effectiveness analyses, will have important implications for translating similar strategies to other minority communities in sustainable ways. TRIAL REGISTRATION/BACKGROUND:This study protocol has been approved and is made available on ClinicalTrials.gov by NCT03188094 as of 15 June 2017.

A distal psychosocial factor, perceived powerlessness, has been found to predict various sexual risk behaviors among youth, yet no studies have assessed mediators or moderators in this relationship. Using a demographically diverse, longitudinal sample of urban youth (N = 257), this study assessed whether the need for sexual validation mediates the relationship between perceived powerlessness and sexual risk behaviors and to assess whether this mediated pathway is moderated by socioeconomic status and gender. The mean age of the participants was 21 years old (range: 15-24) and the majority of the sample identified as Black (65%) and female (62%). The results of structural equation modeling showed that the need for sexual validation mediated perceived powerlessness and condomless sex at last sex among Black youth. The need for sexual validation mediated perceived powerlessness and concurrent sexual partnerships among White youth and depended on levels of socioeconomic status. Sexual risk behavior interventions should provide youth with increased opportunities that encourage feelings of validation from other personal achievements in addition to sex while simultaneously addressing the structural conditions that drive young people to feel powerless.

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.

To address a shortage in research on Pre-Exposure Prophylaxis (PrEP) amongst women at high risk of HIV acquisition, this study explored the attitudes and preferences of female sex workers (FSW) (n = 15) and women who inject drugs (WWID) (n = 16) to existing (e.g., pill) and new (e.g., injection, implant) PrEP modalities, in Baltimore, Maryland, U.S.A. This study reports on seven focus groups conducted between December 2016 and April 2017 and aims to provide new insights into FSW and WWID attitudes and preferences towards three different PrEP delivery methods (i.e., PrEP pill, PrEP implant, PrEP injection). Results draw upon the PrEP care continuum framework and distill existing factors, including lack of control over side effects with new, longer lasting modalities, better privacy with injections, increased adherence with reduced dosing schedules from longer lasting PrEP and new factors such as perceptibility concerns with respect to the PrEP implant relevant to PrEP uptake and adherence among two important overlapping, at-risk populations. The study contributes to a better understanding of barriers and facilitators to uptake and adherence for FSW and WWID around both existing and new PrEP modalities, with implications for future clinical trials and PrEP interventions with at risk-populations.

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.

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.

Women who are structurally vulnerable are at heightened risk for HIV/STIs. Identifying typologies of structural vulnerability that drive HIV/STI risk behavior is critical to understanding the nature of women's risk. Latent class analysis (LCA) was used to classify exotic dancers (n = 117) into subgroups based on response patterns of four vulnerability indicators. Latent class regression models tested whether sex- and drug-related risk behavior differed by vulnerability subgroup. Prevalence of vulnerability indicators varied across housing instability (39%), financial insecurity (39%), limited education (67%), and arrest history (36%). LCA yielded a two-class model solution, with 32% of participants expected to belong to a "high vulnerability" subgroup. Dancers in the high vulnerability subgroup were more likely to report sex exchange (OR = 8.1, 95% CI, 1.9-34.4), multiple sex partnerships (OR = 6.4, 95% CI, 1.9-21.5), and illicit drug use (OR = 17.4, 95% CI, 2.5-123.1). Findings underscore the importance of addressing inter-related structural factors contributing to HIV/STI risk.

Urban female exotic dancers are thought to experience unique risk for violence and barriers to care, though limited research has focused on this aspect of urban sex industries. We characterize recent client-perpetrated and intimate partner violence (IPV) and their correlates, and describe women's intentions for violence-related help-seeking, among venue-based exotic dancers in a high-risk urban environment. We conducted a cross-sectional study with new female exotic dancers (n = 117) in Baltimore, MD. Over one third (36%) reported intimate partner violence (IPV), and 16% reported client physical or sexual violence, in the six months prior to the survey. Both forms of violence were correlated with arrest, sex trade, substance use, and childhood abuse. Violence-related help-seeking intentions were highest for club management. Intentions to seek help from police and violence-related support hotlines were lowest among those with recent experiences of violence. Recent violence, particularly from intimate partners, was pervasive in this sample of female exotic dancers, and enabled by substance use, criminal history, and sex trade. Preferences for help within venues, rather than the justice sector and publicly funded support services, indicate the need for systems reform to meet the needs of this high-risk group of women.
