People who are incarcerated have a disproportionately high risk of contracting human immunodeficiency virus (HIV). While there is no known cure for HIV, there are biomedical approaches that can successfully manage the virus and prevent its transmission. A total of 267 men who are incarcerated completed a cross-sectional survey focused on cancer health, HIV prevention, and mental health in three state prisons. The mean age was 39 years. The majority had an annual income of US$10,000 or less, self-identified as heterosexual, not married, had children, did not have any military status, and identified as African American/Black. Less than 4% indicated that they had heard about Pre-Exposure Prophylaxis (PrEP), and only 3% had heard of Post-Exposure Prophylaxis (PEP). PrEP and PEP effectively prevent HIV infection, but little attention has focused on increasing the knowledge and awareness of these HIV prevention interventions in the incarcerated population.

Impact Statement
The mixed methods study found a positive association between Mental Health First Aid training and an
increase in correctional officers attitudes regarding referring people who are incarcerated to mental health professionals. Mental Health First Aid training can be helpful for correctional officers to equip them with appropriate skills to identify mental health challenges and substance use in correctional settings. However, correctional officers also report that the systems currently in place to connect people struggling with mental illness must be revamped.

The digestive health of African American/Black male immigrants in the United States has not been previously studied. Much of what is known about gastrointestinal (GI) concerns in this population is based on studies conducted on the overall Black American population. The purpose of this narrative study was to understand how African American/Black male immigrants with GI concerns navigated their GI condition. Fifteen African American/Black male immigrants from various cities in the United States participated in two remote focus groups to discover what motivates them to take control of their illness. Narrative analysis was used to analyze the qualitative data. Most men, 47% (n = 7), did not have health insurance, and 67% (n = 10) reported their income was less than US$52,000. The themes identified were: (1) lack of knowledge of GI, (2) denial of initial diagnosis, (3) self-discipline, (4) positive provider interactions, (5) health as a priority, and (6) advice to other African American/Black male immigrants experiencing GI. A strengths-based approach is necessary for describing the health-seeking behaviors among African American/Black male immigrants.

Introduction The COVID-19 pandemic’s economic fallout has further exacerbated the health and well-being among Hispanics/Latinos, who maybe overrepresented in essential job industries and are vulnerable to experiencing food insecurity. This study explores whether the COVID-19 pandemic affected food security status differently among Latino/Hispanic essential and non-essential workers in the United States.

Methods The COVID-19 Latino health cross-sectional survey was conducted and administered in person and virtually. Bivariate analyses and chi-square tests were performed to investigate the association between essential worker status and changes in food security status during the COVID-19 pandemic. All reported p-values were two-sided; p < 0.05 was considered statistically significant.
Results Of the 869 Hispanic/Latino respondents, 393 (45%) were deemed essential workers, and 476 (55%) were nonessential workers. About 22% of essential workers reported a household income of less than $20,000, whereas 19% of nonessential workers had an income above $100,000. Half (54%) of essential workers reported food insecurity. Over one-third (35%) of essential and 22% of non-essential workers reported increased food insecurity during the COVID-19 pandemic.
Moreover, there was a significant difference in food insecurity status between essential and non-essential Hispanic/Latino workers (p < 0.001).
Conclusion The results underscore the prevalence of food insecurity due to the COVID-19 pandemic and the need to create comprehensive food policies that address the lack of availability of adequate food among Hispanic/Latino essential workers who already face pandemic-related challenges.

Colorectal Cancer is the second leading cause of cancer-related deaths in the United States. In this program, we use an ecological model to help Newark residents complete colorectal screening through fecal immunochemical testing (FIT). We provide education and motivational interviewing to address barriers and concerns about screening.

It has been well established that mental health problems disproportionately burden a significant number of individuals who are incarcerated. The literature suggests that one way of offsetting the deleterious effects of prison life among inmates is to build and use available social support resources before incarceration and during community reintegration. Our studies have investigated different forms of support that could significantly improve mental health outcomes among formerly incarcerated men of color in New York City. To learn more about how to use social support in mitigating recidivism and reducing poor health, please read some of our findings and solutions:
