Vulnerability to Hypertension Is a Major Determinant of Racial Disparities in Alzheimer's Disease Risk.

ABSTRACT:

Background

Higher incidence levels of Alzheimer's disease (AD) in Black Americans are well documented. However, quantitative explanations of this disparity in terms of risk-factor diseases acting through well-defined pathways are lacking.

Methods

We applied a Blinder-Oaxaca-based algorithm modified for censored data to a 5% random sample of Medicare beneficiaries age 65+ to explain Black/White disparities in AD risk in terms of differences in exposure and vulnerability to morbidity profiles based on 10 major AD-risk-related diseases.

Results

The primary contribution to racial disparities in AD risk comes from morbidity profiles that included hypertension with about 1/5th of their contribution due to differences in prevalence (exposure effect) and 4/5ths to differences in the effects of the morbidity profile on AD risk (vulnerability effect). In total, disease-related effects explained a higher proportion of AD incidence in Black Americans than in their White counterparts.

Conclusions

Disease-related causes may represent some of the most straightforward targets for targeted interventions aimed at the reduction of racial disparities in health among US older adults. Hypertension is a manageable and potentially preventable condition responsible for the majority of the Black/White differences in AD risk, making mitigation of the role of this disease in engendering higher AD incidence in Black Americans a prominent concern.

Project description:BackgroundHypertension adversely impacts the multiple sclerosis (MS) disease course and is more common among Black Americans. Disparities in care due to structural racism may lead to suboptimal hypertension detection and control in Black American MS patients.ObjectivesTo determine if uncontrolled hypertension is more common in Black or White Americans with MS and whether race impacts the likelihood of receiving anti-hypertensive treatment.MethodsA retrospective cohort study was conducted using longitudinal data from American participants in the Multiple Sclerosis Partners Advancing Technology and Health Solutions (MS PATHS) multi-institutional registry. Data was collected from 7 sites in the United States between May 2015 and November 2020. Patients with uncontrolled hypertension, defined as ≥2 blood pressure measurements ≥140/90 mmHg, were identified in the dataset. Racial differences in uncontrolled hypertension and odds of anti-hypertensive treatment were evaluated using logistic regression. Predictors of anti-hypertensive treatment in those with uncontrolled hypertension were determined by race.ResultsThe analysis included 10,673 MS patients, of whom 1,442 (13.5%) were Black Americans. Despite a lower mean age (45.7 vs. 49.2 years), Black Americans had a 31% increased odds of uncontrolled hypertension compared to White Americans. After adjustment for relevant covariates, mean systolic blood pressure was 1.84 mmHg (95% confidence interval=1.07-2.61) higher in Black Americans than White Americans, and mean diastolic blood pressure was 1.28 mmHg (95% confidence interval=0.74-1.82) higher. Black Americans were also more likely to be on anti-hypertensive therapy (OR=1.68, 95% confidence interval=1.30-2.18) and were exposed to an adjusted average of 0.61 (95% confidence interval=0.45-0.78) more anti-hypertensive treatments than White Americans (p<0.001). Age, comorbid diabetes mellitus, and comorbid hyperlipidemia were positively associated with use of anti-hypertensive treatments in all patients with uncontrolled hypertension.ConclusionBlack American MS patients have significantly increased odds of uncontrolled hypertension, but also higher odds of receiving anti-hypertensive treatment.

Project description:Background: An increasing body of evidence has linked fructose intake to colorectal cancer (CRC). African Americans (AAs) consume greater quantities of fructose and are more likely to develop right-side colon cancer than European Americans. Objective: We examined the hypothesis that fructose consumption leads to genomic differences associated with CRC tumor biology. Methods: DNA methylation data from this study was obtained using the Illumina Infinium MethylationEPIC kit (GSE151732). Right and left colon differentially methylated regions (DMRs) were identified using DMRcate through analysis of fructose consumption in normal AA colon biopsies (n=79) undergoing screening colonoscopy. Secondary analysis of CRC tumors was carried out using data derived from TCGA-COAD, GSE101764 and GSE193535. Right colon organoids derived from AA normal colon tissues were exposed to 4.4mM of fructose for 72 hours. Fructose-associated differentially expressed genes (DEGs) were identified using DESeq2. This package was also used to identify DEGs in CRC tumors from TCGA-COAD. Results: We identified 4,263 right colon fructose-associated DMRs (FDR<0.05). In contrast, only 24 DMRs survived multiple testing corrections (FDR<0.05) in matched, left colon. Almost 50% of right colon fructose-associated DMRs overlapped regions implicated in CRC in at least one of three datasets. A highly significant enrichment was also observed between genes corresponding to right colon fructose-associated DMRs and DEGs associated with fructose exposure in AA right colon organoids (P=3.28E-30). Further, overlapping and significant enrichments for a number of fatty acid metabolism, glycolysis and cell proliferation pathways were also found. By further examining the overlap of genes within these pathways that were also differentially expressed in TCGA-COAD, our analysis reveals potential role for PFKP and ANKRD23 in fructose-mediated CRC risk. Conclusions: Our data support that dietary fructose exerts a greater CRC risk-related effect in right than left colon among AAs, alluding to its potential role in contributing to racial disparities in CRC.

Project description:ImportanceLiving donor kidney transplant (LDKT) is the ideal treatment for end-stage kidney disease, but racial disparities in LDKT have increased over the last 2 decades. Recipient clinical and social factors do not account for LDKT racial inequities, although comprehensive measures of community-level vulnerability have not been assessed.ObjectiveTo determine if racial disparities persist in LDKT independent of community-level vulnerability.Design, setting, and participantsThis retrospective, multicenter, cross-sectional study included data from 19 287 adult kidney-only transplant recipients in the Scientific Registry of Transplant Recipients. The study included individuals who underwent transplant between January 1 and December 31, 2018.ExposuresRecipient race and the 2018 US Centers for Disease Control and Prevention Social Vulnerability Index (SVI). Census tract-level SVI data were linked to census tracts within each recipient zip code. The median SVI measure among the census tracts within a zip code was used to describe community-level vulnerability.Main outcomes and measuresKidney transplant donor type (deceased vs living). Modified Poisson regression was used to evaluate the association between SVI and LDKT, and to estimate LDKT likelihood among races, independent of community-level vulnerability and recipient-level characteristics.ResultsAmong 19 287 kidney transplant recipients, 6080 (32%) received LDKT. A total of 11 582 (60%) were male, and the median (interquartile range) age was 54 (43-63) years. There were 760 Black LDKT recipients (13%), 4865 White LDKT recipients (80%), and 455 LDKT recipients of other races (7%; American Indian, Asian, multiracial, and Pacific Islander). Recipients who lived in communities with higher SVI (ie, more vulnerable) had lower likelihood of LDKT compared with recipients who lived in communities with lower SVI (ie, less vulnerable) (adjusted relative risk [aRR], 0.97; 95% CI, 0.96-0.98; P < .001). Independent of community-level vulnerability, compared with White recipients, Black recipients had 37% lower likelihood (aRR, 0.63; 95% CI, 0.59-0.67; P < .001) and recipients of other races had 24% lower likelihood (aRR, 0.76; 95% CI, 0.70-0.82; P < .001) of LDKT. The interaction between SVI and race was significant among Black recipients, such that the disparity in LDKT between Black and White recipients increased with greater community-level vulnerability (ratio of aRRs, 0.67; 95% CI, 0.51-0.87; P = .003).Conclusions and relevanceCommunity-level vulnerability is associated with access to LDKT but only partially explains LDKT racial disparities. The adverse effects of living in more vulnerable communities were worse for Black recipients. The interaction of these constructs is worrisome and suggests evaluation of other health system factors that may contribute to LDKT racial disparities is needed.
