Adherence to a culturally adapted soul food vegan diet among African American adults increases diet quality compared to an omnivorous diet in the NEW Soul Study.

Adherence to a vegan diet may lower risk of cardiovascular disease among African Americans (AAs). Feasibility and sustainability of adopting a vegan diet may be challenging among AAs who live in regions where soul food is a predominant cuisine. Our hypothesis was that AAs randomized to a culturally adapted vegan diet will have greater adherence to their assigned diet compared with those randomized to a culturally adapted omnivorous diet. AAs (N = 113) with overweight/obesity from South Carolina were included. Dietary intake was measured at months 0, 3, 6, and 12 using 24-hour recalls. Adherence was defined based on recommended animal product intake for each group. Differences in nutrient intakes and dietary indices (Alternative Healthy Eating Index 2010 and healthy plant-based diet index) between groups were evaluated using t-tests. At 12 months, adherence was higher to the vegan (51%) versus omnivorous (35%) diet. Participants assigned to the vegan diet had higher intake of carbohydrates (P = .01) and fiber (P < .001), and lower intake of cholesterol P< .001) and protein (P = .001) compared with participants assigned to the omnivorous diet. Participants adherent to the vegan diet had lower cholesterol intake (P < .001) and higher fiber intake (P = .02) compared with those adherent to the omnivorous diet. Compared with those assigned to the omnivorous diet, participants assigned to the vegan diet had higher Alternative Healthy Eating Index 2010 (P = .01) and healthy plant-based diet index (P < .001) scores. AAs with overweight/obesity were more adherent to a culturally adapted vegan diet versus an omnivorous diet after 1 year, and nutrient and food group intake changes were sustained.

The shadow of fear: hate crime victimization and stress after Charlottesville.

Introduction: Recent years have witnessed an increase in highly publicized attacks targeting members of ethnoracial and religious minority groups. To date, existing research has primarily focused on the tendency for such "trigger events" to generate violent aftershocks. We argue that beyond such ripple effects, highly salient trigger events significantly increase hate-crime related stress among racial and ethnic minorities. Additionally, we explore whether these effects are limited to the group most clearly targeted, or if they "spill over" to other minoritized communities. Methods: To study reactions to hate crimes, we draw upon national survey data (N = 1,122) in combination with a natural experiment involving the Unite the Right rally and vehicle attack in Charlottesville, Virginia in August 2017. We employ an "unexpected event during survey" design to estimate the causal effect of the Charlottesville rally on stress about hate crimes. Results: We first show that there was an increase in anti-Black hate crimes in the 2 weeks following the Charlottesville incident. We also find a corresponding increase in stress due to the perception of personal vulnerability to hate crimes among African-Americans. However, we do not observe a significant increase in levels of stress following the trigger event among Hispanics and Asian Americans. Discussion: Our results suggest that highly publicized instances of intergroup violence can have significant impacts on stress about hate crime victimization within the target group. However, we find that this effect is short-lived, and that both violent aftershocks and the general climate of fear spurred by hate crimes may be racially bounded.

Extended genome-wide association study employing the African genome resources panel identifies novel susceptibility loci for Alzheimer's disease in individuals of African ancestry.

INTRODUCTION: Despite a two-fold risk, individuals of African ancestry have been underrepresented in Alzheimer's disease (AD) genomics efforts. METHODS: Genome-wide association studies (GWAS) of 2,903 AD cases and 6,265 controls of African ancestry. Within-dataset results were meta-analyzed, followed by functional genomics analyses. RESULTS: A novel AD-risk locus was identified in MPDZ on chromosome (chr) 9p23 (rs141610415, MAF = 0.002, P = 3.68×10-9). Two additional novel common and nine rare loci were identified with suggestive associations (P < 9×10-7). Comparison of association and linkage disequilibrium (LD) patterns between datasets with higher and lower degrees of African ancestry showed differential association patterns at chr12q23.2 (ASCL1), suggesting that this association is modulated by regional origin of local African ancestry. DISCUSSION: These analyses identified novel AD-associated loci in individuals of African ancestry and suggest that degree of African ancestry modulates some associations. Increased sample sets covering as much African genetic diversity as possible will be critical to identify additional loci and deconvolute local genetic ancestry effects. HIGHLIGHTS: Genetic ancestry significantly impacts risk of Alzheimer's Disease (AD). Although individuals of African ancestry are twice as likely to develop AD, they are vastly underrepresented in AD genomics studies. The Alzheimer's Disease Genetics Consortium has previously identified 16 common and rare genetic loci associated with AD in African American individuals. The current analyses significantly expand this effort by increasing the sample size and extending ancestral diversity by including populations from continental Africa. Single variant meta-analysis identified a novel genome-wide significant AD-risk locus in individuals of African ancestry at the MPDZ gene, and 11 additional novel loci with suggestive genome-wide significance at P < 9×10-7. Comparison of African American datasets with samples of higher degree of African ancestry demonstrated differing patterns of association and linkage disequilibrium at one of these loci, suggesting that degree and/or geographic origin of African ancestry modulates the effect at this locus. These findings illustrate the importance of increasing number and ancestral diversity of African ancestry samples in AD genomics studies to fully disentangle the genetic architecture underlying AD, and yield more effective ancestry-informed genetic screening tools and therapeutic interventions.

Assessment of unmeasured confounding in the association between perceived discrimination and mental health in a predominantly African American cohort using g-estimation.

BACKGROUND: Perceived discrimination in health care settings can have adverse consequences on mental health in minority groups. However, the association between perceived discrimination and mental health is prone to unmeasured confounding. The study aims to quantitatively evaluate the influence of unmeasured confounding in this association, using g-estimation. METHODS: In a predominantly African American cohort, we applied g-estimation to estimate the association between perceived discrimination and mental health, adjusted and unadjusted for measured confounders. Mental health was measured using clinical diagnoses of anxiety, depression and bipolar disorder. Perceived discrimination was measured as the number of patient-reported discrimination events in health care settings. Measured confounders included demographic, socioeconomic, residential and health characteristics. The influence of confounding was denoted as α1 from g-estimation. We compared α1 for measured and unmeasured confounding. RESULTS: Strong associations between perceived discrimination in health care settings and mental health outcomes were observed. For anxiety, the odds ratio (95% confidence interval) unadjusted and adjusted for measured confounders were 1.30 (1.21, 1.39) and 1.26 (1.17, 1.36), respectively. The α1 for measured confounding was -0.066. Unmeasured confounding with α1=0.200, which was over three times that of measured confounding, corresponds to an odds ratio of 1.12 (1.01, 1.24). Similar results were observed for other mental health outcomes. CONCLUSION: Compared with measured confounding, unmeasured that was three times measured confounding was not enough to explain away the association between perceived discrimination and mental health, suggesting that this association is robust to unmeasured confounding. This study provides a novel framework to quantitatively evaluate unmeasured confounding.

PSA Stratification for Predicting Advanced Prostate Cancer Events in Men Approaching Age-Limits for Recommended Screening.

PURPOSE: To quantify the ability of various PSA values in predicting the likelihood of developing metastatic or fatal prostate cancer in older men. MATERIALS/METHODS: We used a random sample of patients in the United States Veterans Health Administration to identify 80,706 men who had received PSA testing between ages 70 to 75. Our primary endpoint was time to development of either metastatic prostate cancer or death from prostate cancer. We used cumulative/dynamic modeling to account for competing events (death from non-prostate cancer causes) in studying both the discriminative ability of PSA as well as for positive predictive value and negative predictive value at three time points. RESULTS: PSA demonstrated time-dependent predictive discrimination, with receiver operating characteristic area under the curve at 5, 10, and 14 years decreasing from 0.83 to 0.77 to 0.73, respectively, but without statistically significant difference when stratified by race. At PSA thresholds between 1 and 8 ng/mL, the positive predictive value of developing advanced prostate cancer was significantly greater in Black than White patients. For instance, at a PSA > 3, at 5, 10, and 14 years, White patients had 2.4%, 2.9%, and 3.7% risk of an event, whereas Black patients had 4.3%, 6.5%, and 8.3% risk. CONCLUSIONS: In men aged 70 to 75 deciding whether to cease PSA testing with borderline-elevated PSA values, the risk of developing metastatic or fatal prostate cancer is quantifiable and relatively low. Risk assessment in this setting must account for the higher incidence of prostate cancer in Black men.

Impact of DAA Treatment for HCV on Hepatocellular Carcinoma in a Predominately African American Population.

PURPOSE: This study tested the hypothesis that our predominately AA medical center population would demonstrate a decline in HCV-driven HCC diagnosis following the initiation of DAA treatment in 2014. Also evaluated was whether achieving an SVR prior to diagnosis of HCC improved outcomes in patients who had an HCV diagnosis after completion of treatment. METHODS: All patients with HCC seen at the Detroit Medical Center from 2009 to 2021 were identified using ICD-10 codes, and medical records were evaluated. Outcomes were evaluated as either alive or death/hospice as of December of 2022. RESULTS: There were 461 patients with HCC of whom 433 (94%) had racial information in the database (AA = 351; non-AA = 82). HCC incidence regardless of race peaked in 2017, with a subsequent decline through 2021. HCV as a risk factor was higher in AA as compared to non-AA (85% vs. 53% p = 0.0001). Outcome (alive vs. death/hospice) was better for SVR patients compared to untreated patients (54% vs. 19%; p = 0.0009). HCC patients who achieved SVR also had better liver function at diagnosis as defined by Child-Pugh score (74% vs. 49% Class A p = 0.04) at the time of diagnosis. CONCLUSIONS: Racial disparity in HCC etiology was confirmed with AA more likely to have HCV than non-AA. The reduction in HCC patients with HCV confirms the impact of DAA treatment and prior successful treatment of HCV yields better outcomes. Increasing HCV treatment rates especially in AA patients will have a major impact on HCC development and treatment outcomes. WHAT IS KNOWN: • African Americans are more likely to have HCV infection as compared to non-AA. • Hepatocellular carcinoma is increasing in incidence in the US. • The role of HCV in the development of HCC remains to be further investigated. WHAT IS NEW: • HCC diagnosis in a single urban medical center study increased from 2009 as a result of HCV as a risk factor. • HCC declined post 2018 due primarily to a reduction in HCV infection as the risk factor. • African Americans were more likely to have HCV as the risk factor as compared to non-AA patients who were more likely to have no known risk factor on record (i.e., cryptogenic).

Rationale, design, and participant characteristics of the FAITH! Heart Health+ study: An exploration of the influence of the social determinants of health, stress, and structural racism on African American cardiovascular health.

BACKGROUND: African Americans (AAs) face cardiovascular health (CVH) disparities linked to systemic racism. The 2020 police killing of Mr. George Floyd in Minneapolis, Minnesota, alongside the COVID-19 pandemic, exacerbated adverse psychosocial factors affecting CVH outcomes among AAs. This manuscript describes the study protocol and participant characteristics in an ancillary study exploring the relationship between biopsychosocial factors and CVH among AAs. METHODS: Using a community-based participatory approach, a mixed-methods ancillary study of 58 AA participants from an overarching randomized control trial (RCT) was conducted. Baseline RCT health assessments (November 2020) provided sociodemographic, medical, and clinical data. Subsequent health assessments (February-December 2022) measured sleep quality, psychosocial factors (e.g., high-effort coping), biomarkers (e.g., cortisol), and cardiovascular diagnostics (e.g., cardio-ankle vascular index). CVH was assessed using the American Heart Association Life's Simple 7 (LS7) (range 0 to 14, poor to ideal) and Life's Essential 8 (LE8) scores (range 0 to 100, low to high). Correlations between these scores will be examined. Focus group discussions via videoconferencing (March to April 2022) assessed psychosocial and structural barriers, along with the impact of COVID-19 and George Floyd's killing on daily life. RESULTS: Participants were predominantly female (67%), with a mean age of 54.6 [11.9] years, high cardiometabolic risk (93% had overweight/obesity and 70% hypertension), and moderate LE8 scores (mean 57.4, SD 11.5). CONCLUSION: This study will enhance understanding of the associations between biopsychosocial factors and CVH among AAs in Minnesota. Findings may inform risk estimation, patient care, and healthcare policies to address CVD disparities in marginalized populations.

Involvement of Reactive Oxygen Species in Prostate Cancer and Its Disparity in African Descendants.

Reactive oxygen species (ROS) participate in almost all disorders, including cancer. Many factors, including aging, a high-fat diet, a stressful lifestyle, smoking, infection, genetic mutations, etc., lead to elevated levels of ROS. Prostate cancer, the most prevalent type of cancer in senior American men and the second leading cause of cancer mortality in American men, results from chronic oxidative stress. The doubled incident rate as well as the doubled mortality numbers of prostate cancer have persisted in African Americans in comparison with Caucasian Americans and other racial groups, indicating a prostate cancer disparity in African American men. In this review, we mainly focus on the latest findings on ROS in prostate cancer development and progression within the last five years to update our understanding in this area, as several comprehensive literature reviews addressing oxidative stress and/or inflammation in prostate cancer before 2020 are available. In addition to other known factors such as socioeconomic disadvantage, cultural mistrust of the health care system, etc. that are long-existing in the African American group, we also summarize the latest evidence that demonstrated high systemic oxidative stress and inflammation in African Americans for their potential contribution to the racial prostate cancer disparity in this population.

A Culturally Adapted Perioperative Mental Health Intervention for Older Black Surgical Patients.

OBJECTIVES: Perioperative mental health of older Black surgical patients is associated with poor surgical outcomes; however, evidence-based perioperative interventions are lacking. Our two study objectives included: first, examine factors affecting perioperative care experiences of older Black surgical patients with mental health problems, and second, ascertain design and implementation requirements for a culturally-adapted perioperative mental health intervention. DESIGN SETTING AND PARTICIPANTS: We conducted six focus groups with older Black patients (n = 15; ≥50 years; surgery within the past 5 years and/or interest in mental health research; history of distress, anxiety, or depression coping with surgery/hospitalization/) from a large academic medical center. We engaged study partners, including interventionists and community members, to gather insights on intervention and implementation needs. We followed a hybrid inductive-deductive thematic approach using open coding and the National Institute on Minority Health and Health Disparities Research Framework. RESULTS: Patients reported that their psychological well-being and long-term mental health outcomes were not appropriately considered during perioperative care. Perceived stressors included interpersonal and structural barriers to using mental healthcare services, clinician treatment biases and ageism in care, and lack of healthcare professional connections/resources. Patients utilized various coping strategies, including talk therapy, faith/spirituality, and family and friends. CONCLUSION: This study offers valuable insights into the experiences of older Black surgical patients and the critical elements for developing a personalized perioperative mental health intervention to support their well-being before, during, and after surgery. Our findings demonstrated a need for a patient-centered and culturally adapted intervention targeting the individual/behavioral and interpersonal levels. Informed by the cultural adaptation framework, we propose a multi-component intervention that integrates psychological and pharmacological components.

Using a Randomized Clinical Trial to Test the Efficacy of a Culturally Responsive Mobile Health Application in African Americans.

Mindfulness is a promising health promotion strategy for African Americans, and it is imperative that culturally responsive mindfulness approaches be accessible to this population. One way to address this need is to develop and test if culturally responsive mobile health (mhealth) applications are efficacious in reducing stress-related outcomes in this population. With this goal in mind, we employed a repeated-measures randomized control trial (RCT) across a 12-week intervention period to evaluate if participants in the intervention group outperformed a wait-list control group in reductions in stress, depressive symptoms, anxiety, emotional regulation difficulties as well as in increases in self-compassion, resilience, and mindfulness attitudes and behaviors. Our sample included 170 Black/African American participants who were randomly assigned to either the intervention condition (n = 84) or the wait-list control group (n = 86). Participants in the intervention condition reported more self-compassion, used more mindfulness, and had greater self-efficacy using mindfulness; yet, no other differences were evident. Participants expressed high levels of satisfaction with the app and gave it a positive rating for its relevance to their lives. These findings support the efficacy of a culturally responsive mindfulness mHealth app to enhance self-compassion and increase the use of health-promoting behaviors, like mindfulness, among African Americans. Implications for future research are discussed.

Factors predicting primary and booster COVID-19 vaccination in a community sample of African American men and women in the United States Midwest.

COVID-19 has disproportionately burdened impoverished minority communities. This study recruited an age- and gender-diverse community sample of 541 Black adults in a United States Midwestern city with large racial health disparities, with the aim of examining factors associated with COVID-19 vaccination. All participants completed measures assessing their COVID-19 vaccination status (unvaccinated, received primary vaccination, or received primary plus booster vaccination) as well as demographic characteristics, socioeconomic factors, health and health system factors, and health behavior theory constructs related to vaccination. In this predominantly low-income sample, 55% of participants had received primary COVID-19 vaccination and 31% of the sample had received a booster dose. Multiple regression analyses established that having primary vaccination was significantly predicted by older age, political identification as Democrat, education beyond high school, barriers to accessing health care, as well as higher trust of vaccine benefits, less preference for natural immunity, stronger social norms favoring vaccination, and perceiving higher levels of collective responsibility. Surprisingly, higher global medical mistrust and difficulty with healthcare access were associated with vaccination. The model explained 76% of the variance in primary COVID-19 vaccination. Having received a COVID-19 booster was predicted by older age, previous COVID-19 infection, higher trust in vaccine benefits, and fewer worries about unforeseen future effects of vaccination. Study findings identified factors associated with COVID-19 vaccine uptake in racial minority communities, and support the benefits of interventions that harness social network supports for vaccination, address community vaccine concerns, and appeal to collective responsibility to promote vaccine uptake.

Capturing the perspectives of African American informal dementia caregivers: a phenomenological study.

Dementia can be overwhelming to families and their caregivers. Informal caregiving is a widespread mode of providing dementia care in African American communities, yet impact of caregiving on informal or family caregivers in African American communities is burdensome. This study aimed to describe the lived experiences of informal caregivers of African American People Living with Dementia (PLWD) to understand their perceptions of dementia and dementia care, caregiver support needs, and service needs. Interpretive phenomenological qualitative inquiry guided this study to understand caregivers' experiences and needs. Ten family caregivers of African American PLWD in the community participated in this study. Data were collected through in-depth interviews and a diary study approach to document and interpret caregivers' experiences. The data analysis was based on procedures of content analysis. Four major themes emerged from the in-depth interviews: caregiver burden, familism, lack of information and community-based resources, and desire and need for culturally appropriate community-based resources. Triangulated diary entry data complemented the in-depth interviews with similar themes. This study highlights how African American informal caregivers of PLWD face various caregiving needs and challenges in dementia care including lack of culturally appropriate community resources and information. The study illustrates that African American cultural beliefs of familism are significant aspects of their caregiving experience and their coping strategies. These study results provide a useful foundation for various stakeholders to develop culturally targeted interventions and programs to support African American informal caregivers and their family members with dementia.

Content validation of a Facebook HPV vaccination promotion intervention (#HPVvaxtalks) created for young Black adults (18-26 years old).

BACKGROUND: Despite the expansion in human papillomavirus (HPV) vaccination recommendations, vaccine uptake and completion remain low among Black individuals. An 8-week Facebook intervention (#HPVvaxtalks) was developed to increase knowledge and awareness of HPV risk factors, risk perceptions, and vaccination intention and uptake. This article details the formative phase of experts' feedback and participants' satisfaction on the components of the #HPVvaxtalks for content useability, acceptability, relevance, and visual appeal to inform further refinements. METHOD: A convenience sample of 5 experts and 13 young Black adults were invited to provide feedback on #HPVvaxtalks intervention content. The experts reviewed and provided feedback via a survey and open-ended questions. After incorporating suggestions from experts' feedback, 13 participants viewed #HPVvaxtalks posts, took part in a virtual focus group, and completed a survey. Qualitative data were thematically analyzed and integrated with survey results. RESULTS: Experts and participants mean age were 41.9 ± 2.3 and 21.2 ± 1.9 years, respectively. Experts and participants reported positive ratings for intervention posts, including useability, acceptability, relevance, and visual appeal. Data provided areas for improvements of #HPVvaxtalks.    CONCLUSION: Experts indicated strong content validity and participants showed satisfaction with #HPVvaxtalks content. Ensuring acceptability, relevance, and appeal of the intervention for the target population is an integral part of intervention development.

Chronic stress exposure, social support, and sleep quality among African Americans: findings from the National Survey of American Life-Reinterview.

OBJECTIVE: The purpose of this study was to determine whether social support from extended family and church members moderate the association between chronic stress exposure and sleep quality in a nationally representative sample of African American adults. DESIGN: Data from African American respondents aged 18 and older were drawn from the National Survey of American Life-Reinterview. The analytic sample for this study included 1,372 African American adults who attended religious services at least a few times a year, as the church-based relationship measures were only assessed for these individuals. Self-reported sleep quality was assessed by sleep satisfaction, trouble falling asleep, and restless sleep. Chronic stress exposure was measured by a nine-item index. OLS and logistic regression were used to estimate the relationship between chronic stress exposure, extended family and church relationships, and sleep quality. RESULTS: The data indicated that chronic stress exposure was associated with decreased sleep satisfaction, increased likelihood of trouble falling asleep and restless sleep. Receiving emotional support from family and more frequent contact with church members were associated with decreased restless sleep. Emotional family support moderated the associations between chronic stress exposure and trouble falling asleep and restless sleep. The positive associations between chronic stress exposure and these two sleep quality measures were attenuated among respondents who received high levels of emotional support from their family. CONCLUSIONS: Together, these findings underscore the detriment of chronic stress exposure to African Americans' sleep quality and suggest that extended family members are effective stress coping resources and play an important role in this population's sleep quality.

Cancer health awareness through screening and education: A community approach to healthy equity.

BACKGROUND: The Cancer Health Awareness through screeNinG and Education (CHANGE) initiative delivers cancer awareness education with an emphasis on modifiable risk factors and navigation to screening for prostate, breast, and colorectal cancers to residents of public housing communities who experience significant negative social determinants of health. METHODS: Residents of five communities participated. Community advisory board members were recruited and provided feedback to local environmental change projects, recruitment, and community engagement at each site. At each site, four education sessions were provided by trained facilitators on cancer risk factors and etiology, racial disparities, eligibility for cancer screening, and participation in clinical trials. Attendance, knowledge, attitudes and beliefs about cancer, and height, weight, and waist circumference were measured at baseline and 1-week post-CHANGE sessions. RESULTS: 90 residents (60% 65 and older years old, 33% male, 60% High School education, 93% AA) participated in the program. 95% completed post-intervention evaluation. Participants were eligible for breast (n = 12), prostate (n = 15), and colorectal screening (n = 25) based on American Cancer Society guidelines, and 22 for tobacco cessation; 21 participants accepted navigation assistance for these services. At post-test, participants significantly increased in knowledge and behaviors around obesity/overweight risk for cancer, nutrition, and physical activity. Colorectal, prostate, and breast cancer knowledge scores also increased, but were not significant. CONCLUSIONS: CHANGE participants demonstrated improved health knowledge and intentions to improve their modifiable health behaviors. Participants reported being motivated and confident in seeking preventive care and satisfaction with community engagement efforts. Replication of this project in similar communities may improve knowledge and health equity among underserved populations.

Race Adjustment of Pulmonary Function Tests in the Diagnosis and Management of COPD: A Scoping Review.

Aim: Increasing evidence suggests that the inclusion of self-identified race in clinical decision algorithms may perpetuate longstanding inequities. Until recently, most pulmonary function tests utilized separate reference equations that are race/ethnicity based. Purpose: We assess the magnitude and scope of the available literature on the negative impact of race-based pulmonary function prediction equations on relevant outcomes in African Americans with COPD. Methods: We performed a scoping review utilizing an English language search on PubMed/Medline, Embase, Scopus, and Web of Science in September 2022 and updated it in December 2023. We searched for publications regarding the effect of race-specific vs race-neutral, race-free, or race-reversed lung function testing algorithms on the diagnosis of COPD and COPD-related physiologic and functional measures. Joanna Briggs Institute (JBI) guidelines were utilized for this scoping review. Eligibility criteria: The search was restricted to adults with COPD. We excluded publications on other lung disorders, non-English language publications, or studies that did not include African Americans. The search identified publications. Ultimately, six peer-reviewed publications and four conference abstracts were selected for this review. Results: Removal of race from lung function prediction equations often had opposite effects in African Americans and Whites, specifically regarding the severity of lung function impairment. Symptoms and objective findings were better aligned when race-specific reference values were not used. Race-neutral prediction algorithms uniformly resulted in reclassifying severity in the African Americans studied. Conclusion: The limited literature does not support the use of race-based lung function prediction equations. However, this assertion does not provide guidance for every specific clinical situation. For African Americans with COPD, the use of race-based prediction equations appears to fall short in enhancing diagnostic accuracy, classifying severity of impairment, or predicting subsequent clinical events. We do not have information comparing race-neutral vs race-based algorithms on prediction of progression of COPD. We conclude that the elimination of race-based reference values potentially reduces underestimation of disease severity in African Americans with COPD.

Association Between Dietary Intake of Phosphorus and Measures of Obesity in the Jackson Heart Study.

BACKGROUND: The relation between phosphorus (P) intake and obesity is equivocal, with hypotheses in both directions. OBJECTIVES: We investigated the relationship between P intake, assessed from a current database, and calculated bioavailable P intake and obesity among African-American adults. METHODS: We examined associations between original and bioavailable P (total, added, and natural) and BMI and waist circumference (WC) in a cross-sectional study of 5306 African-American adults (21-84 y) from the Jackson Heart Study. A total of 3300 participants had complete interviews, valid dietary data, and normal kidney function. Diet was assessed by food frequency questionnaire. A novel algorithm was used to estimate P bioavailability. BMI or WC was regressed on each P variable, adjusting for total energy intake and potential confounders. RESULTS: After adjusting for covariates, original P (total and added) and bioavailable P (total and added) intakes (expressed/100 mg) were associated with BMI (ß: 0.11, 0.67, 0.31, and 0.71, respectively; all P < 0.0001). Neither original nor bioavailable natural P was significantly associated (ß: -0.03 and 0.09, respectively; both P > 0.05). When added and natural P were included in the same model, added P (original and bioavailable) intakes remained strongly associated with BMI (0.70 and 0.73, respectively; both P < 0.0001). Similar results were seen for WC. Intake of original added P tended to be more strongly associated with BMI, in females (ß: 0.72; P < 0.0001) than in males (ß: 0.56; P = 0.003) (P-interaction = 0.06). CONCLUSIONS: We found that greater intake of added, not natural, which may be a proxy for intake of processed foods was associated with higher BMI and WC. These were somewhat stronger when bioavailability was considered and for women than for men. Further investigation is needed to fully understand the mechanisms driving these associations.

Capturing men's perspectives on prevalence, existing resources, and solutions to depression and anxiety using community-based participatory research and focus groups.

OBJECTIVE: Men are predisposed to suffer from unaddressed depression and anxiety. The purpose of this study was to capture the perceptions of men in three urban, racially/ethnically diverse, under-resourced, and impoverished neighborhoods around this health issue. The results were used to design a resident-driven solution to this health disparity. DESIGN: Design This study utilized a focus group method within the ideological perspective of community-based participatory research (CBPR). SAMPLE: Sample The researchers recruited 50 Black, Hispanic, and White men aged 23-83 years to participate in this study during the summer of 2021. MEASUREMENTS: Measurements Data were collected via six homogeneous, Zoom-based focus groups. Five of the focus groups were offered in English and the sixth in Spanish. RESULTS: The men identified themes and subthemes pertaining to the perception of widespread depression and anxiety in their neighborhoods, existing typical and atypical community resources, and suggested solutions to this health disparity. These results were translated into a solution involving the training of five male, lay mental health ambassadors. CONCLUSIONS: Policies and solutions to issues of mental health disparity must be informed by the communities that they intend to serve. CBPR is a robust vehicle for empowering communities to address the healthcare issues facing them.

Peer Ambassador Perspectives in a Culturally Tailored Self-Management Intervention for African Americans with Type 2 Diabetes: A Qualitative Study.

OBJECTIVE: Diabetes disproportionately affects African Americans, leading to higher morbidity and mortality. This study explores the experiences of African American adults who successfully self-manage their type 2 diabetes (called Peer Ambassadors) and provided phone-based peer support in a 6-month culturally tailored diabetes self-management program for African Americans guided by the information-motivation-behavioral skills model. DESIGN: A group discussion using a semi-structured discussion guide was conducted. Qualitative content analysis was used to identify the facilitators and barriers to completing the role of a Peer Ambassador and to develop strategies for overcoming possible challenges in the future. SETTING: Key informant discussions were conducted in a community location to gain insights into Ambassadors' motivations and challenges in delivering peer support. PARTICIPANTS: Three Peer Ambassadors completed ethics training and peer mentor training and received a phone call guide before providing support to their peers. RESULTS: There were four core themes related to Peer Ambassador experiences: (1) Motivation to be a Peer Ambassador, (2) program elements that supported Peer Ambassador role, (3) key elements of achieving engagement, and (4) challenges related to being a Peer Ambassador. CONCLUSIONS: This study showed Peer Ambassadors in a culturally tailored peer supported self-management program found fulfillment in sharing experiences and supporting peers. They highly valued educational group sessions for knowledge updates and sustaining their health-related goals, suggesting the potential benefits of recognizing milestones or providing advanced training for future program sustainability. Findings suggest the importance of recruiting motivated patients and providing effective facilitation for peer support roles, including addressing barriers such as time commitment and lack of socialization opportunities.

Association between Flavonoid Intake and Cognitive Executive Function among African American and White Adults in the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) Study.

Healthy dietary patterns rich in flavonoids may benefit cognitive performance over time. Among socioeconomically disadvantaged groups, the association between flavonoid intake and measures of cognition is unclear. This study sought to identify associations between flavonoid intake and cognitive performance among Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study participants (n = 1947) across three study visits. Flavonoid intakes were assessed via two 24-h dietary recalls. Cognitive performance was assessed via the Trail Making Test (TMT)-A and TMT-B, which provide measures of attention and executive function, respectively. Mixed effects linear regression was used to model TMT scores over three study visits against visit 1 (v1) flavonoid intake, time (years from v1), and the interaction between v1 flavonoid intake and time, capturing both the cross-sectional association between flavonoid intake and time at v1 as well as the longitudinal association between v1 flavonoid intake and the change in TMT scores over time. Prior to adjustment, inverse cross-sectional associations at v1 were observed between (1) anthocyanidin intake and TMT-A scores for the overall sample and (2) total flavonoid, anthocyanidin, flavan-3-ol, flavone, and flavonol intake and TMT-B scores for the overall sample and among White adults. Only the association between anthocyanidin intake and TMT-B at v1 among White adults persisted after adjustment (for demographic characteristics such as age). One possible explanation for the few significant associations is universally low flavonoid intakes resulting from the consumption of an unhealthy dietary pattern.
