INTRODUCTION/BACKGROUND:Emergency department (ED) patients have higher than average levels of food insecurity. We examined the association between multiple measures of food insecurity and frequent ED use in a random sample of ED patients. METHODS:We completed survey questionnaires with randomly sampled adult patients from an urban public hospital ED (n = 2,312). We assessed food insecurity using four questions from the United States Department of Agriculture Household Food Security Survey. The primary independent variable was any food insecurity, defined as an affirmative response to any of the four items. Frequent ED use was defined as self-report of ≥4 ED visits in the past year. We examined the relationship between patient food insecurity and frequent ED use using bivariate and multivariable analyses and examined possible mediation by anxiety/depression and overall health status. RESULTS:One-third (30.9%) of study participants reported frequent ED use, and half (50.8%) reported any food insecurity. Prevalence of food insecurity was higher among frequent vs. non-frequent ED users, 62.8% vs 45.4% (P <0.001). After controlling for potential confounders, food insecurity remained significantly associated with frequent ED use (adjusted odds ratio 1.48, 95% confidence interval, 1.20-1.83). This observed association was partially attenuated when anxiety/depression and overall health status were added to models. CONCLUSION/CONCLUSIONS:The high observed prevalence of food insecurity suggests that efforts to improve care of ED patients should assess and address this need. Further research is needed to assess whether addressing food insecurity may play an important role in efforts to reduce frequent ED use for some patients.

Twenty men with spinal cord injury (SCI) were randomized into two 16-week intervention groups receiving testosterone treatment (TT) or TT combined with resistance training (TT + RT). TT + RT appears to hold the potential to reverse or slow down bone loss following SCI if provided over a longer period.

Black men who have sex with men (BMSM) are disproportionately incarcerated in the United States. Incarceration is a barrier to health equity and may be a risk factor for experiences of interpersonal violence. However, the effect of incarceration on experienced violence among BMSM is understudied. We examined associations between recent incarceration on subsequent experiences of race- or sexuality-based violence, intimate partner violence, or community violence. We analyzed data from the HPTN 061 study. Analysis includes data on 1,169 BMSM recruited from 6 U.S. cities who were present at baseline as well as 6- and 12-month follow-up interview. We tested if self-reported incarceration between baseline and 6 months was associated with self-reported outcomes between 6 and 12 months using logistic regression with inverse probability of treatment weighting and multiple imputation methods. Experienced outcomes included violence due to race or sexuality, intimate partner violence and aggression, and community violence (i.e., gang violence, robbery, shooting). Approximately 14% reported incarceration between baseline and 6 months and 90% reported experiencing violence between 6 and 12 months. In adjusted analyses, incarceration was associated with subsequent race- or sexuality-based violence [aOR (adjusted odds ratio) range: 1.25-1.41, 95% CI (confidence interval) range: 1.00-1.74], experiences of physical abuse and aggression from intimate partners (aOR: 2.35; 95% CI: 1.50, 3.70) and community violence (OR 1.82; 95% CI: 1.23, 2.72). Recent incarceration experience increased risk of exposure to future violence in this population. Mixed methods research examining mediating paths between and downstream effects of incarceration and violence on the wellbeing and health of BMSM is needed. We implore researchers to study violence and incarceration among BMSM. Practitione should implement strategies such as trauma-informed interventions, and policies strengthening the social and economic support needs of Black populations.

OBJECTIVE:To examine the factor structure of a revised and expanded opioid overdose risk behavior scale and assess its associations with known overdose indicators and other clinical constructs. BACKGROUND:Opioid-related overdose remains high in the U.S. We lack strong instrumentation for assessing behavioral risk factors. We revised and expanded the opioid overdose risk behavior scale (ORBS-1) for use among a broader range of people who use opioids. SETTING & SAMPLING FRAME/UNASSIGNED:Using respondent-driven sampling we recruited adults (18+) reporting current unprescribed opioid use and New York City residence. METHOD/METHODS:Participants (N = 575) completed the ORBS-1, ORBS-2, and a variety of clinical measures and then completed the ORBS-2 and overdose risk outcomes across monthly follow-up assessments over a 13-month period. RESULTS:Principal components analysis was used to identify six ORBS-2 subscales, Prescription Opioid Misuse, Risky Non-Injection Use, Injection Drug Use, Concurrent Opioid and Benzodiazepine Use, Concurrent Opioid and Alcohol Use, and Multiple-Drug Polysubstance Use. All subscales showed moderate non-parametric correlations with the ORBS-1 and with corresponding clinical constructs. Five of the subscales were significantly (p < .01) positively associated with self-reported non-fatal overdose. Of note, the Risky Non-Injection Use subscale was the most strongly associated with past-month overdose indicators. CONCLUSIONS:Psychometrics for the opioid overdose risk behavior subscales identified suggest the ongoing utility of risk behavioral instrumentation for epidemiological research and clinical practice focused on risk communication and minimization. Use of the entire ORBS-2 measure can provide insight into the proximal/behavioral factors of greatest concern to reduce overdose mortality.

Black men who have sex with men (BMSM) have disproportionate HIV/STI acquisition risk. Incarceration may increase exposure to violence and exacerbate psychosocial vulnerabilities, including internalized homophobia, which are associated with HIV/STI acquisition risk. Using data from HIV Prevention Trials Network 061 (N = 1553), we estimated adjusted prevalence ratios (APR) and 95% confidence intervals (CIs) for associations between lifetime burden of incarceration and HIV/STI risk outcomes. We measured associations between incarceration and HIV/STI risk outcomes with hypothesized mediators of recent violence victimization and internalized homophobia. Compared to those never incarcerated, those with 3-9 or ≥ 10 incarcerations had approximately 10% higher prevalence of multiple partnerships. Incarceration burden was associated with selling sex (1-2 incarcerations: APR: 1.52, 95% CI 1.14-2.03; 3-9: APR: 1.77, 95% CI 1.35-2.33; ≥ 10: APR: 1.85, 95% CI 1.37-2.51) and buying sex (≥ 10 incarcerations APR: 1.80, 95% CI 1.18-2.75). Compared to never incarcerated, 1-2 incarcerations appeared to be associated with current chlamydia (APR: 1.47, 95% CI 0.98-2.20) and 3-9 incarcerations appeared to be associated with current syphilis (APR: 1.46, 95% CI 0.92-2.30). Incarceration was independently associated with violence, which in turn was a correlate of transactional sex. Longitudinal research is warranted to clarify the role of incarceration in violence and HIV/STI risk in this population.

Big Events are periods during which abnormal large-scale events like war, economic collapse, revolts, or pandemics disrupt daily life and expectations about the future. They can lead to rapid change in health-related norms, beliefs, social networks and behavioural practices. The world is undergoing such Big Events through the interaction of COVID-19, a large economic downturn, massive social unrest in many countries, and ever-worsening effects of global climate change. Previous research, mainly on HIV/AIDS, suggests that the health effects of Big Events can be profound, but are contingent: Sometimes Big Events led to enormous outbreaks of HIV and associated diseases and conditions such as injection drug use, sex trading, and tuberculosis, but in other circumstances, Big Events did not do so. This paper discusses and presents hypotheses about pathways through which the current Big Events might lead to better or worse short and long term outcomes for various health conditions and diseases; considers how pre-existing societal conditions and changing 'pathway' variables can influence the impact of Big Events; discusses how to measure these pathways; and suggests ways in which research and surveillance might be conducted to improve human capacity to prevent or mitigate the effects of Big Events on human health.

Interactions with the police may result in police brutality, particularly for people of color. Black men who have sex with men (BMSM) face disproportionate risk of police contact and may experience elevated violence risk. We measured longitudinal associations between discriminatory police harassment (DPH) and subsequent risk of a range of interpersonal violence experiences, including intimate partner violence (IPV). In this study, we estimated associations between DPH motivated by racism, homophobia, or both, and subsequent violent experiences (being physically harassed, hit, threatened with weapons, and intimate partner violence) among BMSM. Bivariate and multivariable regression analyses were used to control for demographic and behavioral factors. Among 1160 BMSM included at 12-month follow-up, experiencing DPH motivated by racism and homophobia was associated with over four times the odds of being threatened with violence (AOR 4.85, 95% CI 3.20, 7.33), four times the odds of or experiencing violence defined as being punched, kicked, or beaten, or having an object thrown at them (AOR 4.51, 95% CI 2.82, 7.19), and nearly three times the odds of physical partner abuse (AOR 3.49, 95% CI 1.69, 7.19). Findings suggest that for BMSM, DPH is associated with the threat and experience of violence, with a dose-response relationship between DPH motivated by one or more causes. Given that BMSM are a population particularly vulnerable to both police harassment related to race and sexual orientation and violence coupled with stigma, additional research evaluating mechanisms linking these associations is needed in order to develop additional supportive interventions.

Black sexual minority men (BSMM) and Black transgender women (BTW) have disproportionately high HIV prevalence, making HIV testing critical for treatment and prevention. Racism and homophobia may be barriers to testing among BSMM/BTW, particularly in the context of previous incarceration. We analyzed a subsample (n = 655) of HIV-negative, previously incarcerated BSMM/BTW in the HIV Prevention Trials Network 061 study, generating prevalence ratios and interaction terms testing associations between experienced racism and homophobia with past-year HIV testing. Both racism (aPR = 0.83, 95% CI [0.70, 0.98]) and homophobia (aPR: 0.68, 95% CI [0.48, 0.98]) were associated with lower testing, although their interaction was associated with unexpectedly higher testing (Interaction aPR = 1.77, 95% CI [1.25, 2.49]). Among BSMM/BTW with a history of incarceration, racism and homophobia are barriers to HIV testing. Positive interactions between racism and homophobia could be explained by numerous factors (e.g., resilience, coping) and warrants further study.

OBJECTIVE:We aimed to determine the effectiveness of various preexposure prophylaxis (PrEP) prescription strategies for African-American women impacted by mass incarceration within an urban setting. DESIGN/METHODS:An agent-based model was utilized to evaluate prevention strategies in an efficient, ethical manner. By defining agents, their characteristics and relationships, we assessed population-level effects of PrEP on HIV incidence. METHODS:We tested hypothetical PrEP prescription strategies within a simulation representing the African-American population of Philadelphia, Pennsylvania. Four strategies were evaluated: PrEP for women meeting CDC indicators regarding partner characteristics, PrEP for women with a recently incarcerated male partner, PrEP for women with a recently released male partner and couples-based PrEP at time of release. Interventions occurred alongside scale-up of HAART. We evaluated reductions in HIV transmissions, the number of persons on PrEP needed to avert one HIV transmission (NNT) and the resulting proportions of people on PrEP. RESULTS:Scenarios prescribing PrEP based on criminal justice system involvement reduced HIV transmissions. The NNT ranged from 147 (couples-based scenario) to 300 (recently released scenario). The percentage of the female population covered by PrEP at any one time ranged from 0.14% (couples-based) to 10.8% (CDC-based). CDC-guideline scenarios were consistently less efficient compared to the justice-involved interventions. CONCLUSION/CONCLUSIONS:Expanding PrEP for African-American women and their male partners affected by incarceration should be considered in national HIV prevention goals and correctional facilities leveraged as intervention sites. Partner characteristics in the current CDC indications may be more effective and efficient if guidelines considered criminal justice involvement.

The mental health impact of exposure to police harassment is understudied, particularly among Black men who have sex with men (BMSM), a group at elevated risk of exposure to such discrimination. This study aimed to identify the associations among BMSM between recent police harassment and psychosocial vulnerability, psychological distress, and depression measured six months later. Data come from the HIV Prevention Trials Network (HPTN) 061 Study, a cohort study of BMSM recruited in 6 U.S. cities (Atlanta, GA, Boston, MA, Los Angeles, CA, New York, NY, San Francisco, CA, and Washington DC). Participants completed baseline, 6-month follow-up, and 12-month follow-up interviews. A convenience sample of 1553 BMSM was recruited between July 2009 and October 2010 of whom 1155 returned for a follow-up interview 12 months later. Accounting for previous police interaction, poverty, psychopathology, drug use, and alcohol use, we estimated associations between recent police harassment reported at the 6 month follow-up interview and 12 month outcomes including psychosocial vulnerability (elevated racial/sexual identity incongruence), psychological distress (being distressed by experiences of racism and/or homophobia), and depression. About 60% of men reported experiencing police harassment between the baseline and 6-month interview due to their race and/or sexuality. Adjusted analyses suggested police harassment was independently associated with a 10.81 (95% CI: 7.97, 13.66) point increase and 8.68 (95% CI: 6.06, 11.30) point increase in distress due to experienced racism and distress due to experienced homophobia scores, respectively. Police harassment perceived to be dually motivated predicted disproportionate levels of distress. Police harassment is prevalent and associated with negative influences on psychosocial vulnerability and psychological distress among BMSM. Reducing exposure to police harassment may improve the psychosocial health of BMSM.
