    Analysis of COVID-19 Case Demographics and Disease Outcomes in Gary, Indiana
    (MDPI, 2023-09-07) Sabir, Maryam; Al-Tarshan, Yazan; Snapp, Cameron; Brown, Martin; Walker, Roland; Han, Amy; Kostrominova, Tatiana
    Background: The COVID-19 pandemic further exposed the prevalence of existing health disparities in Black communities in the U.S. The current study evaluates COVID-19 data collected in Gary, Indiana, from June 2020 to June 2021. We hypothesized that the number of COVID-19 cases, hospitalizations, and deaths were influenced by race and income. Methods: In collaboration with the Gary Health Department (GHD), we analyzed demographic data on COVID-19-positive cases. Results: Compared to Gary's non-Black population, age- and population-adjusted rates of hospitalizations and deaths in the Black population were 3-fold (p < 0.0001) and 2-fold (p < 0.05) higher, respectively. This is despite a higher infection rate (p < 0.0001) in the non-Black population. The median household income of a zip code was negatively correlated with COVID-19 hospitalizations (R2 = 0.6345, p = 0.03), but did not correlate with infections and deaths. Conclusions: The current study demonstrates clear health disparities of income and race in the context of COVID-19-related infections and outcomes in the city of Gary. Indiana University School of Medicine Northwest and GHD officials can collaborate to utilize these data for the reallocation of resources and health education efforts in Gary's highly populated, low-income, and predominantly Black neighborhoods. It should also prompt further investigation into national health resource allocation.

    HIV/AIDS and Substance Use Prevention for African American Young Adults: Field Evaluation of “Color it Real”
    (Sage, 2021) Agley, Jon; Xiao, Yunyu; Jayawardene, Wasantha; Gay, Albert; King, Rosemary; Horne, Kelly; Walker, Roland; School of Social Work
    In the United States, African Americans continue to bear a disproportionate amount of risk from HIV and illicit drug use, highlighting the importance of culturally responsive prevention programming. Manualized HIV and substance use prevention curricula that are conceptually African centered are few, and evaluative data of such programs are sparse. This research brief aims to describe a field evaluation of the “Color it Real” (CIR) program, a 6-session, 12-hr HIV and substance use prevention curriculum for African American males and females aged 18 to 24 years. Participants (n = 225) were recruited using convenience sampling from two cities within a high-risk county in Indiana. Attitudes, knowledge, and confidence related to HIV and substance use were assessed before and after the intervention. Wilcoxon and McNemar tests were used to compare pretest and posttest scores, and binary logistic regression models were used to examine sociodemographic associations with outcomes. Among the analytic sample (n = 195), the CIR program was associated with several improved attitudes and increased knowledge related to HIV and substance use, but not with increased confidence in sexual negotiation skills. These findings represent the first published data from CIR since the developers’ original study, and support continued use of the curriculum by our program. Given the positive findings (i.e., attitudes and knowledge) and community receptiveness to CIR, we believe that a randomized, controlled trial of the intervention that includes longitudinal behavioral measurement would be a meaningful addition to prevention research.
