Study protocol: Exploring the use of Family Health Histories in the African American community to reduce health disparities in Flint, Michigan.

Background Health disparities are costly and preventable differences in disease progression that disproportionately affect minority communities such as African Americans. Practices to reduce health disparities can be rooted in prevention, particularly through screening tools. Family Health History tools are preventative screening mechanisms meant to explore family history to better understand how an individual's health can potentially be predicted or impacted. These tools are underutilized in the African American community. Contributions to this underutilization include a lack of cultural tailoring in the tools, a lack of health literacy in community members, and a lack of effective health communication. The Family Health History Study will create a culturally appropriate Family Health History toolkit to increase family health history utilization and ultimately decrease health disparities. Methods The proposed sample will be composed of 195 African American adults ages 18 + who live in Genesee County, Michigan. The study consists of two phases: the development phase and the randomized pilot study phase. The goal of the development phase (n = 95) is to explore how Family Health History toolkits can be modified to better serve the African American community using a community based participatory research approach and to create a culturally tailored family health history toolkit. In the pilot study phase, 100 participants will be randomized to the culturally tailored toolkit or the current standard Family Health History toolkit. Outcomes will include feasibility and acceptability of the intervention. Discussion This study will result in a culturally appropriate Family Health History tool that is co-developed with community members that can be utilized by African American adults to better understand their family health histories.

Perceived Economic Strain, Subjective Social Status, and Colorectal Cancer Screening Utilization in U.S. Men-A Cross-Sectional Analysis.

Although socioeconomic status (SES) is fundamentally related to underutilization of colorectal cancer (CRC) screening, the role of perceived economic strain and subjective social status with CRC screening is understudied. The aim of this study was to investigate whether greater perceived economic strain or lower subjective social status would decrease the odds of CRC screening uptake and being up-to-date with guideline-recommended CRC screening. We also explored interactions with household income and educational attainment. Cross-sectional survey-based data from men aged 45-75 years living in the United States (N = 499) were collected in February 2022. Study outcomes were ever completing a stool- or exam-based CRC screening test and being up-to-date with CRC screening. Perceived economic strain and subjective social status were the predictors. We conducted logistic regression models to estimate odds ratios (OR) and 95% confidence intervals (CI). Greater perceptions of economic strain decreased odds of being up-to-date with CRC screening. Household income modified the association between perceived economic strain and completing a stool-based test; the association was stronger for men from lower-income households. In unadjusted models, higher subjective social status increased odds of completing an exam-based test and being up-to-date with CRC screening. Our findings suggest that experiencing economic strain may interfere with men's CRC screening decisions and may capture additional information about barriers to CRC screening utilization beyond those captured by income or education.

Justice beliefs for self and others: Associations with positive and negative affectivity in African Americans and White Americans.

Prior research has shown that a belief in personal justice (i.e., justice for self) is associated with better health and well-being, whereas a belief in justice more generally (i.e., justice for others) is unrelated. However, an emerging perspective is that racial differences may overlay the relationships between multidimensional beliefs about justice and indices of well-being. This includes that well-being among African Americans may be additionally supported by rejecting rather than endorsing some forms of believing in justice. In the present study, we consider racial similarities and differences in the links between beliefs about justice for self and others and emotional well-being. African Americans (N = 117) and White Americans (N = 188) completed measures of beliefs about justice for self and others, and also measures of dispositional tendencies towards experiencing positive and negative emotion (i.e., positive and negative affectivity). In both groups, beliefs about justice for the self were associated with greater positive affect and reduced negative affect. However, beliefs about justice for others were additionally associated with greater negative affect only among African Americans. The link between justice for others and negative affect among African Americans was not attributable to measurement or mean differences in justice beliefs across racial groups, or to socioeconomic differences. Results align with an emerging perspective that simultaneously endorsing and rejecting justice beliefs may be vital to preserving well-being for some racial minorities.

Personal justice beliefs, everyday discrimination, and carotid intima media thickness in sexual minority men.

OBJECTIVE: Cardiovascular disease (CVD) disproportionately affects sexual minority men (SMM) and is linked to discrimination-related stress. Belief in a just world-including the belief that one personally gets what one deserves (personal justice beliefs)-is a coping strategy that can protect against discrimination-related stress and CVD risk. Here, we examine links between personal justice beliefs, perceived everyday discrimination, and carotid intima media thickness (cIMT)-a measure of atherosclerosis that can indicate subclinical CVD. METHOD: Sexual minority White (29%) and racial minority (African American 18.8%, mixed/other 44.9%) male young adults (N = 69) completed measures of personal justice beliefs and everyday discrimination. cIMT imaging was used to compute common carotid artery (CCA) intima media thickness. RESULTS: Hierarchical multiple regressions revealed associations between justice beliefs, perceived discrimination, and cIMT that were moderated by age. Consistent with prior research, personal justice beliefs predicted less perceived discrimination, especially among older SMM. However, personal justice beliefs were also linked to greater rather than less CCA among older SMM. CONCLUSIONS: Relationships between believing in justice and CVD may be complex among minority groups. Among SMM, the belief in personal justice may reduce perceived discrimination, but may be simultaneously deleteriously associated with biological processes that underlie CVD.

Preventing HIV Among Adolescent Boys and Young Men Through PEPFAR-Supported Voluntary Medical Male Circumcision in 15 Sub-Saharan African Countries, 2018-2021.

Voluntary medical male circumcision (VMMC) is an HIV prevention intervention that has predominantly targeted adolescent and young men, aged 10-24 years. In 2020, the age eligibility for VMMC shifted from 10 to 15 years of age. This report describes the VMMC client age distribution from 2018 to 2021, at the site, national, and regional levels, among 15 countries in southern and eastern Africa. Overall, in 2018 and 2019, the highest proportion of VMMCs were performed among 10-14-year-olds (45.6% and 41.2%, respectively). In 2020 and 2021, the 15-19-year age group accounted for the highest proportion (37.2% and 50.4%, respectively) of VMMCs performed across all age groups. Similarly, in 2021 at the site level, 68.1% of VMMC sites conducted the majority of circumcisions among men aged 15-24 years. This analysis highlights that adolescent boys and young men are the primary recipients of VMMC receiving an important lifetime reduction in HIV risk.

Medical mistrust, culturally targeted message framing, and colorectal cancer screening among African Americans.

Mistrust in the information and treatment provided by medical professionals and organizations hinders cancer screening among African Americans. However, its impact on responses to health messaging aimed at bolstering screening uptake is unknown. The present study examined the effects of medical mistrust on message framing and culturally targeted health messaging about colorectal cancer (CRC) screening. Screening eligible African Americans (N = 457) completed the Group-Based Medical Mistrust scale and then viewed an informational video about CRC risks, prevention, and screening, during which all participants received either a gain or loss-framed message about screening. Half of participants received an additional culturally targeted screening message. After messaging, all participants completed Theory of Planned Behavior measures of CRC screening receptivity, as well as items assessing expectations about experiencing racism when obtaining CRC screening (i.e., anticipatory racism). Hierarchical multiple regressions showed that medical mistrust predicted lower screening receptivity and greater anticipatory racism. Additionally, effects of health messaging were moderated by medical mistrust. Among participants high in mistrust, targeted messaging-regardless of message frame-bolstered normative beliefs about CRC. Additionally, only targeted loss-framed messaging bolstered attitudes toward CRC screening. Although targeted messaging reduced anticipatory racism among participants with high mistrust, anticipatory racism did not mediate messaging effects. Findings indicate medical mistrust may be an important culturally-relevant individual difference to attend to in addressing CRC screening disparities, including its potential to impact responses to cancer screening messaging.

Message Framing for Men? Gender Moderated Effects of Culturally Targeted Message Framing on Colorectal Cancer Screening Receptivity among African Americans.

Receptivity to recommended colorectal cancer (CRC) screening can be enhanced by use of loss-framed health messaging that emphasizes possible consequences of failing to act. However, a simultaneous use of culturally targeted messaging may be needed to achieve effectiveness when loss-framed messaging is used with African Americans, especially to reduce racism-related cognitions aroused by standard loss framing that impede CRC screening receptivity. This study considered whether effects of stand-alone and culturally targeted message framing on CRC screening receptivity differ between African American men and women. African Americans eligible for CRC screening (Men=117, Women=340) viewed an informational video about CRC risks, prevention, and screening, and were randomized to receive a gain or loss-framed message about screening. Half of participants received an additional culturally targeted message. Using the Theory of Planned Behavior, we measured receptivity to CRC screening. We also measured arousal of racism-related cognitions. A significant three-way interaction suggested effects of messaging on CRC screening receptivity were moderated by gender. Participants were no more receptive to CRC screening when standard loss-framing was used, but were more favorable if loss-framing was culturally targeted. However, these effects were more pronounced among African American men. Contrary to prior findings, gender moderated effects of culturally targeted loss-framed messaging were not attributable to reducing racism-related cognitions. Findings add to growing recognition of important nuance in effective use of message framing to also include gender, while suggesting a critical need to explore gender-relevant mechanistic pathways, potentially including how health messaging activates masculinity-related cognitions among African American men.

Voluntary Medical Male Circumcisions for HIV Prevention - 13 Countries in Eastern and Southern Africa, 2017-2021.

In 2007, voluntary medical male circumcision (VMMC) was endorsed by the World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS after it was found to be associated with approximately a 60% reduction in the risk for female-to-male transmission of HIV (1). As a result of this endorsement, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), through partnerships with U.S. government agencies, including CDC, the U.S. Department of Defense, and the U.S. Agency for International Development, started supporting VMMCs performed in prioritized countries in southern and eastern Africa. During 2010-2016, CDC supported 5,880,372 VMMCs in 12 countries (2,3). During 2017-2021, CDC supported 8,497,297 VMMCs performed in 13 countries. In 2020, the number of VMMCs performed declined 31.8% compared with the number in 2019, primarily because of COVID-19-related disruptions to VMMC service delivery. PEPFAR 2017-2021 Monitoring, Evaluation, and Reporting data were used to provide an update and describe CDC's contribution to the scale-up of the VMMC program, which is important to meeting the 2025 Joint United Nations Programme on HIV/AIDS (UNAIDS) target of 90% of males aged 15-59 years having access to VMMC services in prioritized countries to help end the AIDS epidemic by 2030 (4).

Moderators of the effects of perceived racism and discrimination on cancer-related health behaviors among two samples of African Americans.

BACKGROUND: Assumptions regarding within-race variation in the associations between measures of discrimination racism and health-related behaviors among African Americans have been largely unexplored. METHODS: We conducted secondary analyses of two studies to examine support for a model which describes several theoretical moderators of the effects of discrimination and racism on health behaviors. The first study examined the effects of group-based behavioral information and racial identity on the association between perceived racism and requests for at home colorectal cancer screening tests among a sample of 205 geographically diverse African Americans who participated in an online experiment from 2019 to 2020. RESULTS: Group-based behavioral information attenuated the association between perceived racism and requests for at-home screening kit. In the absence of group-based behavioral information, perceived racism was positively associated with screening kit requests for African Americans with weaker racial identity and negatively associated with requests for African Americans with stronger racial identity. The second study examined the influence of personal and group-based perceived discrimination, and behavior-relevant affective information related to a breast cancer risk notification, on 89 Michigan dwelling African American women's self-reported physician communication from 2015 to 2016. Results showed that perceived group-based discrimination was positively associated with physician communication in the absence of negative affective information, and perceived personal discrimination was negatively associated with physician communication as positive affective information increased. CONCLUSIONS: Together, these results support our theoretical model highlighting variation in the effects of discrimination and racism on health behaviors among African Americans, and indicates group-relevant behavioral information, racial identity, behavior relevant affective information, and target of discrimination as moderators of the effect. Implications for conceptualizing the effects of racism and discrimination and for examining racially targeted interventions are discussed.

Writing about justice and injustice: Complex effects on affect, performance, threat, and biological responses to acute social stress among african American women and men.

OBJECTIVE: Brief, culturally-tailored, and scalable stress coping interventions are needed to address a broad range of stress-related health disparities, including among African Americans. In this study, we develop two brief justice writing interventions and demonstrate a methodological approach for evaluating how prompting African Americans to think about justice and injustice can alter responses to acute social stress. METHODS: African American women and men were randomized to a neutral writing condition or one of two justice-based writing interventions, which prompted them to recall past experiences of personal justice - with (adjunctive injustice) or without (personal justice-only) recalling and writing about injustice. Participants then completed a modified Trier Social Stress Test, during which they received feedback on poor performance. We measured cognitive performance, affect, and perceived threat in response to task feedback. We also measured blood pressure and salivary cortisol stress responses. RESULTS: Men experienced more positive emotion, performed better on the stressor task, and were less threatened by poor performance feedback in the personal justice-only condition. Men also had lower systolic blood pressure reactivity in the justice writing conditions compared to control. Women experienced less positive emotion, performed worse on the stressor task, and were more threatened by feedback in the personal justice-only condition. Women also had lower cortisol recovery after the stressor task in the adjunctive injustice condition. CONCLUSION: Thinking about justice and injustice may alter performance, affect, threat, and biological responses to acute social stress. Still, gender differences highlight that justice thinking is likely to produce heterogeneous and complex stress coping responses among African Americans.

Complex effects of racism and discrimination on African Americans' health and well-being: Navigating the status quo.

Most research on the effects of racism and discrimination on the health and well-being of African Americans utilize a deficit perspective, one that homogeneously paints African Americans as disadvantaged victims. Such approaches do little to highlight the variability in the effects of racism and discrimination on relevant outcomes, and the resources that African Americans have drawn upon to navigate an environment characterized by varying levels of racialized hostility. The goal of this special issue is to inspire more refined conceptualizations of how African Americans navigate an often-hostile status quo in service of their health and well-being. The articles in this special issue examine within-race heterogeneity in African Americans' responses to varying manifestations of racism and discrimination, as well as subsequent heterogeneity in the effects of racism and discrimination on African Americans' health and well-being at the individual level. The commentaries and articles address the goals of this special issue in three broad categories of health outcomes: biological/physiological, mind and brain, and health behavior. These contributions demonstrate several critical themes that can guide future work to achieve a more comprehensive understanding of the heterogeneity in the effects of racism and discrimination on health and well-being among African Americans.

Results of an African American-targeted norm-based colorectal cancer screening intervention: a pilot study.

Lower colorectal cancer screening rates among African Americans contribute to higher colorectal cancer incidence and mortality. We tested the effects of a racially-targeted messaging intervention that used favorable behavioral norm information to increase uptake of at-home Fecal Immunochemical Test (FIT) Kits. We expected stronger intervention effects among African Americans with stronger racial identity. Eligible African Americans were randomized to one of four intervention conditions: injunctive norm message, descriptive norm message, both messages, neither message. The norm-based messages were delivered via an animated video health message. Background variables, constructs defined by the theory of planned behavior, racial identity, screening modality preferences, and uptake and return of FIT Kits were assessed. Of 205 participants, 111(54%) requested FIT Kits. Contrary to hypotheses, multigroup path analyses indicated stronger effects of targeted messages among African Americans with weaker racial identity. Findings highlight the importance of within-race heterogeneity in the receptivity to racially-targeted health messages.

Culturally targeted message framing and colorectal cancer screening preferences among African Americans.

OBJECTIVE: The current study investigated whether culturally targeted message frames alter preferences for specific colorectal cancer (CRC) screening modalities among African Americans. METHOD: African Americans who were eligible for CRC screening (N = 457) viewed a video about CRC risks, prevention, and recommended screening options. Participants then received a gain or loss-framed message about screening, with half of participants viewing an additional culturally targeted message about overcoming disparities in CRC through screening. Participants reported their desired thoroughness in CRC screening and preferences for being screened using colonoscopy, sigmoidoscopy, or stool-based fecal immunochemical testing. RESULTS: Relative to gain-framing, loss-framed messaging enhanced desired thoroughness in CRC screening. Targeted loss-framing enhanced preferences for colonoscopy and decreased preferences for stool-based FIT screening. CONCLUSIONS: Findings demonstrate that message framing and culturally targeted messaging can impact CRC screening preferences. Altering preferences may carry implications for reducing CRC screening disparities among African Americans. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Effects of COVID-19 Pandemic on Voluntary Medical Male Circumcision Services for HIV Prevention, Sub-Saharan Africa, 2020.

Beginning in March 2020, to reduce COVID-19 transmission, the US President's Emergency Plan for AIDS Relief supporting voluntary medical male circumcision (VMMC) services was delayed in 15 sub-Saharan African countries. We reviewed performance indicators to compare the number of VMMCs performed in 2020 with those performed in previous years. In all countries, the annual number of VMMCs performed decreased 32.5% (from 3,898,960 in 2019 to 2,631,951 in 2020). That reduction is largely attributed to national and local COVID-19 mitigation measures instituted by ministries of health. Overall, 66.7% of the VMMC global annual target was met in 2020, compared with 102.0% in 2019. Countries were not uniformly affected; South Africa achieved only 30.7% of its annual target in 2020, but Rwanda achieved 123.0%. Continued disruption to the VMMC program may lead to reduced circumcision coverage and potentially increased HIV-susceptible populations. Strategies for modifying VMMC services provide lessons for adapting healthcare systems during a global pandemic.

Defining the Global Research and Programmatic Agenda and Priority Actions for Voluntary Medical Male Circumcision for HIV Prevention.

PURPOSE OF REVIEW: Since 2007, voluntary medical male circumcision (VMMC) programs have been associated with substantially reduced HIV incidence across 15 prioritized countries in Eastern and Southern Africa. Drawing on the programmatic experience of global VMMC leaders, this report reviews progress made in the first 15 years of the program, describes programmatic and research gaps, and presents considerations to maximize the impact of VMMC. RECENT FINDINGS: Overall, key programmatic and research gaps include a lack of robust male circumcision coverage estimates due to limitations to the data and a lack of standardized approaches across programs; challenges enhancing VMMC uptake include difficulties reaching populations at higher risk for HIV infection and men 30 years and older; limitations to program and procedural quality and safety including variations in approaches used by programs; and lastly, sustainability with limited evidence-based practices. Considerations to address these gaps include the need for global guidance on estimating coverage, conducting additional research on specific sub-populations to improve VMMC uptake, implementation of responsive and comprehensive approaches to adverse event surveillance, and diversifying financing streams to progress towards sustainability. This report's findings may help establish a global VMMC research and programmatic agenda to inform policy, research, and capacity-building activities at the national and global levels.

Consolidated Overview of Notifiable Adverse Events in the U.S. President's Emergency Plan for AIDS Relief's Voluntary Medical Male Circumcision Program Through 2020.

PURPOSE OF REVIEW: Through December 2020, the U.S. President's Emergency Plan for AIDS Relief (PEPFAR) supported more than 25 million voluntary medical male circumcisions (VMMC) as part of the combined HIV prevention strategy in 15 African countries. PEPFAR monitors defined adverse events (AEs) occurring within 30 days of VMMC through its notifiable adverse event reporting system (NAERS). All NAERS reports through December 2020 were reviewed to quantify AE type, severity, and relation to the VMMC procedure. Interventions to improve client safety based on NAERS findings are described. RECENT FINDINGS: Fourteen countries reported 446 clients with notifiable adverse events (NAEs); 394/446 (88%) were determined VMMC-related, representing approximately 18 NAE reports per million circumcisions. Fatalities comprised 56/446 (13%) with 24/56 (43%) of fatalities determined VMMC-related, representing 0.96 VMMC-related fatalities per million circumcisions. The remaining 390 NAEs were non-fatal with 370/390 (95%) VMMC-related. Multiple programmatic changes have been made based on NAERS data to improve client safety. Client safety is paramount in this surgical program designed for individual and population-level benefit. Surveillance of rare but severe complications following circumcision has identified pre-existing or new safety concerns and guided continuous programmatic improvement.

Patient perceptions by race of educational animations about living kidney donation made for a diverse population.

INTRODUCTION: This qualitative study sought to identify potential design and delivery alterations to inform cultural adaptation of educational animations about living donor kidney transplantation (LDKT)-previously developed for a diverse population-to better fit Black Americans' needs. METHODS: We conducted a secondary analysis of 88 transcripts derived from interviews and focus groups conducted with diverse target users (62 kidney failure patients, 36 prior/potential donors, and 11 care partners) to develop 12 animations about LDKT, named KidneyTIME. Statements were abstracted and coded pertaining to cognitive and communication barriers to LDKT, and the perceived value of using the videos to learn and share the information with social network members using content analysis. Incidence counts of each content code were also calculated to assess differences between Black and non-Black patients. RESULTS: Cognitive barrier codes included lack of knowledge, ambivalence, and concern for donor. Communication barrier codes included reluctance and difficulty talking about LDKT. Cognitive facilitating codes included attention-getting, efficient learning, manageable content, emotional impact, and new knowledge. Communication facilitating codes included delivery through many dissemination channels and broadly shareable. Compared to non-black patients (n = 33) Black patients (n = 29) more often stated concern for donor and reluctance/difficulty talking about LDKT as barriers, and less often stated efficient learning and manageable content as facilitators. CONCLUSION: Findings highlight the value of LDKT informational content that is visually appealing, digestible, non-threatening, and highly shareable. Heterogeneity may exist when considering access and intervention preferences in using KidneyTIME videos and highlight a potential for further cultural targeting or tailoring.

The Serological Sciences Network (SeroNet) for COVID-19: Depth and Breadth of Serology Assays and Plans for Assay Harmonization.

In October 2020, the National Cancer Institute (NCI) Serological Sciences Network (SeroNet) was established to study the immune response to COVID-19, and "to develop, validate, improve, and implement serological testing and associated technologies" (https://www.cancer.gov/research/key-initiatives/covid-19/coronavirus-research-initiatives/serological-sciences-network). SeroNet is comprised of 25 participating research institutions partnering with the Frederick National Laboratory for Cancer Research (FNLCR) and the SeroNet Coordinating Center. Since its inception, SeroNet has supported collaborative development and sharing of COVID-19 serological assay procedures and has set forth plans for assay harmonization. To facilitate collaboration and procedure sharing, a detailed survey was sent to collate comprehensive assay details and performance metrics on COVID-19 serological assays within SeroNet. In addition, FNLCR established a protocol to calibrate SeroNet serological assays to reference standards, such as the U.S. severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) serology standard reference material and first WHO international standard (IS) for anti-SARS-CoV-2 immunoglobulin (20/136), to facilitate harmonization of assay reporting units and cross-comparison of study data. SeroNet institutions reported development of a total of 27 enzyme-linked immunosorbent assay (ELISA) methods, 13 multiplex assays, and 9 neutralization assays and use of 12 different commercial serological methods. FNLCR developed a standardized protocol for SeroNet institutions to calibrate these diverse serological assays to reference standards. In conclusion, SeroNet institutions have established a diverse array of COVID-19 serological assays to study the immune response to SARS-CoV-2 and vaccines. Calibration of SeroNet serological assays to harmonize results reporting will facilitate future pooled data analyses and study cross-comparisons. IMPORTANCE SeroNet institutions have developed or implemented 61 diverse COVID-19 serological assays and are collaboratively working to harmonize these assays using reference materials to establish standardized reporting units. This will facilitate clinical interpretation of serology results and cross-comparison of research data.

Early-Onset Colorectal Cancer Survival Differences and Potential Geographic Determinants Among Men and Women in Utah.

By 2030, early-onset colorectal cancer (EOCRC) is expected to become the leading cancer-related cause of death for people age 20 to 49. To improve understanding of this phenomenon, we analyzed the geographic determinants of EOCRC in Utah by examining county-level incidence and mortality. We linked data from the Utah Population Database to the Utah Cancer Registry to identify residents (age 18-49) diagnosed with EOCRC between 2000 and 2020, and we used spatial empirical Bayes smoothing to determine county-level hotspots. We identified 1,867 EOCRC diagnoses (52.7% in male patients, 69.2% in non-Hispanic White patients). Ten counties (34%) were classified as hotspots, with high EOCRC incidence or mortality. Hotspot status was unrelated to incidence rates, but non-Hispanic ethnic-minority men (incidence rate ratio, 1.49; 95% CI, 1.15-1.91), Hispanic White men and women (incidence rate ratio, 2.24; 95% CI, 2.00-2.51), and Hispanic ethnic-minority men and women (incidence rate ratio, 4.59; 95% CI, 3.50-5.91) were more likely to be diagnosed with EOCRC. After adjustment for income and obesity, adults living in hotspots had a 31% higher hazard for death (HR, 1.31; 95% CI, 1.02-1.69). Survival was poorest for adults with a late-stage diagnosis living in hotspots (chi square (1) = 4.0; p = .045). Adults who were married or who had a life partner had a lower hazard for death than single adults (HR, 0.73; 95% CI, 0.58-0.92). The risk for EOCRC is elevated in 34% of Utah counties, warranting future research and interventions aimed at increasing screening and survival in the population age 18 to 49.
