Racial Disparities and Cardiometabolic Risk: New Horizons of Intervention and Prevention

Cardiometabolic deaths in black and white men: Tracing the risks from early- to mid-adulthood

Objective

This study aimed to estimate and compare cardiometabolic disease (CMD) mortality in U.S. Black and White men during the transition from early adulthood to middle age.

Methods

Using 2022 National Vital Statistics System data and standard period life table methods, we estimated the risk of CMD death in hypothetical cohorts of Black and White men from age 25 to 45 years. We estimated cumulative risk, excess mortality, years of lost life (YLL), and proportion of deaths due to CMD, stratifying by metabolic and cardiovascular disease.

Results

Of the 325,134 Black men aged 25 years in the initial cohort, the cumulative risk of cardiometabolic death before age 45 was one in 63 individuals or 1.58 %. For White men, the risks were markedly lower. Of the 1,185,384 White men aged 25 years in the initial cohort, the cumulative risk of cardiometabolic death before age 45 was one in 158 individuals or 0.63 %. The study also found that of the 5141 expected CMD deaths in the Black cohort, 3090 or 60.10 % were excess deaths relative to the White cohort. Additionally, the proportion of all deaths due to CMD among Black men was 19.15 % rising from 6.02 % at age 25 to 38.00 % at age 45, compared with 11.10 % among White men, increasing from 4.57 % at age 25 to 19.79 % at age 45. The YLL for Black men averaged 6.72 months per person while White men averaged 2.94 months.

Conclusions

This investigation shows profound racial disparities in CMD mortality from early to mid-adulthood.

Particles and Prejudice: Nanomedicine Approaches to Reducing Health Disparities in Endometrial Cancer

Endometrial cancer is the most common gynecological malignancy worldwide and unfortunately has a much higher mortality rate in Black women compared with White women. Many potential factors contribute to these mortality rates, including the underlying effects of systemic and interpersonal racism. Furthermore, other trends in medicine have potential links to these rates including participation in clinical trials, hormone therapy, and pre-existing health conditions. Addressing the high incidence and disparate mortality rates in endometrial cancer requires novel methods, such as nanoparticle-based therapeutics. These therapeutics have been growing in increasing prevalence in pre-clinical development and have far-reaching implications in cancer therapy. The rigor of pre-clinical studies is enhanced by the likeness of the model to the human body. In systems for 3D cell culture, for example, the extracellular matrix mimics the tumor more closely. The increasing emphasis on precision medicine can be applied to cancer using nanoparticle-based methods and applied to pre-clinical models by using patient-derived model data. This review highlights the intersections of nanomedicine, precision medicine, and racial disparities within endometrial cancer and provides insights into reducing health disparities using recent scientific advances on the nanoscale.

The Association of Weight Categories in Adolescence with Cardiovascular Morbidity in Young Adult Israeli Arabs-A Nationwide Study

Objectives. The health consequences of adolescent obesity are understudied in young adult Israeli Arabs. We aimed to evaluate the association of weight categories during adolescence with hypertension (HTN), diabetes mellitus type 2 (DM2), and the composite endpoint of ischemic stroke (IS), myocardial infarction (MI), and heart failure (HF) in young adult Israeli Arabs on a nationwide level. Methods. A retrospective cohort study of 53,726 Arab adolescents born from 1988-1992 was conducted. The cohort was followed, beginning with BMI measurements at ages 17-19 years, until whichever came first among the diagnosis of outcome disease, death, discontinuation of health insurance, or age of 30 years. Results. The incidence (95% CI) of HTN, DM2, and the composite endpoint of IS, MI, and HF was 138.2 (129.1-147.9), 136.7 (127.6-146.3), and 27.3 (23.3-31.7) cases per 105 person-years, respectively. The risk for DM and HTN increased gradually, starting from the 'overweight' category, and reaching fully adjusted HRs (95% CI) of 2.80 (1.82-4.30), and 1.97 (1.31-2.96), respectively, in the 'class 3 obesity' category. The Hazard ratio (HR) for the composite endpoint, its incidence and components, was highest in the 'overweight' category (aHR of 1.64 (1.08-2.50)). Conclusions. The findings emphasize the long-term health consequences of adolescent obesity in early adulthood and, hence, the need for interventions aimed at reducing the rate of adolescent overweight and obesity. The finding of a very high rate of DM2 incidence in early adulthood, even among adolescents without obesity, necessitates an integrated public health approach to all risk factors to prevent DM2 in this population.

Aging, Race, and Health Disparities: Recommendations From the Research Centers Collaborative Network

Racial disparities in adverse health outcomes with aging have been well described. Yet, much of the research focuses on racial comparisons, with relatively less attention to the identification of underlying mechanisms. To address these gaps, the Research Centers Collaborative Network held a workshop on aging, race, and health disparities to identify research priorities and inform the investigation, implementation, and dissemination of strategies to mitigate disparities in healthy aging. This article provides a summary of the key recommendations and highlights the need for research that builds a strong evidence base with both clinical and policy implications. Successful execution of these recommendations will require a concerted effort to increase participation of underrepresented groups in research through community engagement and partnerships. In addition, resources to support and promote the training and development of health disparities researchers will be critical in making health equity a shared responsibility for all major stakeholders.

Mindfulness and Cardiometabolic Health During Pregnancy: An Integrative Review

Objectives

Cardiometabolic health during pregnancy has potential to influence long-term chronic disease risk for both mother and offspring. Mindfulness practices have been associated with improved cardiometabolic health in non-pregnant populations. The objective was to evaluate diverse studies that explored relationships between prenatal mindfulness and maternal cardiometabolic health.

Method

An integrative review was conducted in January 2023 across five databases to identify and evaluate studies of diverse methodologies and data types. Quantitative studies that examined mindfulness as an intervention or exposure variable during pregnancy and reported any of the following outcomes were considered: gestational weight gain (GWG), blood glucose, insulin resistance, gestational diabetes, inflammation, blood pressure, hypertensive disorders of pregnancy. Qualitative studies were included if they evaluated knowledge, attitudes, or practices of mindfulness in relation to the above-mentioned outcomes during pregnancy.

Results

Fifteen eligible studies were identified, and 4 received a "Good" quality rating (1/7 interventional, 1/5 observational, 2/2 qualitative). Qualitative studies revealed interest among pregnant women in mindfulness-based practices for managing GWG. Some beneficial effects of mindfulness interventions on maternal glucose tolerance and blood pressure were identified, but not for other cardiometabolic outcomes. Observational studies revealed null direct associations between maternal trait mindfulness and cardiometabolic parameters, but one study suggests potential for mindful eating to mitigate excess GWG and insulin resistance.

Conclusions

There currently exists limited quality evidence for mindfulness practices to support prenatal cardiometabolic health. Further rigorous studies are required to understand whether prenatal mindfulness-based interventions, either alone or in combination with other lifestyle modalities, can benefit cardiometabolic health.

Nutritional Aspects to Cardiovascular Diseases and Type 2 Diabetes Mellitus

PURPOSE OF REVIEW

In this narrative review, we discuss the current evidence related to the role of dietary interventions to prevent and treat type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD). We also propose alternative therapeutic strategies other than weight loss in this population, namely, improvements in cardiorespiratory fitness and its determinants.

RECENT FINDINGS

While weight loss has been consistently associated with the prevention of T2DM and improvements in glycemic control in those with established diseases, its role in preventing and treating CVD is less clear. In fact, in this setting, improvements in diet quality have provided greater benefits, suggesting that this might represent an alternative, or an even more effective strategy than energy-restriction. Improvements in diet quality, with and without caloric restriction have been shown to improve CVD risk and to prevent the development of T2DM in individuals at risk; however, with regard to glycemic control in patients with T2DM, any dietary intervention resulting in significant weight loss may produce clinically meaningful benefits. Finally, dietary interventions with and without energy restriction that can improve cardiorespiratory fitness, even in absence of weight loss in patients with obesity, should be encouraged.

Evaluation and Optimization of Diabetic Retinopathy Screenings for Uninsured Latinx Patients in a Resource-Limited Student-Run Free Clinic

Background

Diabetic retinopathy (DR) is a sight-threatening condition that causes progressive retina damage. Student-run free clinics represent a valuable opportunity to provide DR screenings to high-risk populations. We characterized the patient population, evaluated the performance, and conducted a needs assessment of DR screenings at the University of California, San Diego Student-Run Ophthalmology Free Clinic, which provides care to predominantly uninsured, Latino patients.

Methods

Retrospective chart review was conducted of all patients seen at the free clinic since 2019 with a diagnosis of type II diabetes. Date and outcome of all DR-related screenings or visits from 2015 onward, demographics information, and DR risk factors such as A1c and insulin dependence were recorded. Predictors of diabetic retinopathy and frequency of DR screenings for each patient were analyzed using multiple logistic regression, t-test for equality of means, and Pearson's correlation.

Results

Of 179 uninsured diabetic patients receiving care at the free clinic, 71% were female and average age was 59. 83% had hypertension, 93% had hyperlipidemia, and 79% had metabolic syndrome. Prevalence of non-proliferative DR was 34% and that of proliferative DR was 15% in diabetic patients. The free clinic capacity in recent years plateaued at just under 50% of patients seen for DR screening or visit per year, though average wait time was over 2 years between visits. Patients with higher no-show rates had less frequent DR screenings. Chronic kidney disease and poor glycemic control were the strongest predictors of DR.

Conclusion

The student-run free ophthalmology clinic has been effective in providing screening and follow-up care for DR patients. Creation of a protocol to identify which patients are at highest risk of DR and should be seen more urgently, addressing no-shows, and implementation of a tele-retina program are potential avenues for improving clinic efficiency in a resource-limited setting for vulnerable populations.

Novel Prediction Equations for Absolute Risk Assessment of Total Cardiovascular Disease Incorporating Cardiovascular-Kidney-Metabolic Health: A Scientific Statement From the American Heart Association

Cardiovascular-kidney-metabolic (CKM) syndrome is a novel construct recently defined by the American Heart Association in response to the high prevalence of metabolic and kidney disease. Epidemiological data demonstrate higher absolute risk of both atherosclerotic cardiovascular disease (CVD) and heart failure as an individual progresses from CKM stage 0 to stage 3, but optimal strategies for risk assessment need to be refined. Absolute risk assessment with the goal to match type and intensity of interventions with predicted risk and expected treatment benefit remains the cornerstone of primary prevention. Given the growing number of therapies in our armamentarium that simultaneously address all 3 CKM axes, novel risk prediction equations are needed that incorporate predictors and outcomes relevant to the CKM context. This should also include social determinants of health, which are key upstream drivers of CVD, to more equitably estimate and address risk. This scientific statement summarizes the background, rationale, and clinical implications for the newly developed sex-specific, race-free risk equations: PREVENT (AHA Predicting Risk of CVD Events). The PREVENT equations enable 10- and 30-year risk estimates for total CVD (composite of atherosclerotic CVD and heart failure), include estimated glomerular filtration rate as a predictor, and adjust for competing risk of non-CVD death among adults 30 to 79 years of age. Additional models accommodate enhanced predictive utility with the addition of CKM factors when clinically indicated for measurement (urine albumin-to-creatinine ratio and hemoglobin A1c) or social determinants of health (social deprivation index) when available. Approaches to implement risk-based prevention using PREVENT across various settings are discussed.

Lifestyle Behaviors and Cardiometabolic Diseases by Race and Ethnicity and Social Risk Factors Among US Young Adults, 2011 to 2018

Background Cardiometabolic health has been worsening among young adults, but the prevalence of lifestyle risk factors and cardiometabolic diseases is unclear. Methods and Results Adults aged 18 to 44 years were included from the National Health and Nutrition Examination Survey, 2011 to 2018. Age-standardized prevalence of lifestyle risk factors and cardiometabolic diseases was estimated overall and by demographic and social risk factors. A set of multivariable logistic regressions was sequentially performed by adjusting for age, sex, social risk factors, and lifestyle factors to determine whether racial and ethnic disparities in the prevalence of cardiometabolic diseases may be attributable to differences in social risk factors and lifestyle factors. Appropriate weights were used to ensure national representativeness of the estimates. A total of 10 405 participants were analyzed (median age, 30.3 years; 50.8% women; 32.3% non-Hispanic White). The prevalence of lifestyle risk factors ranged from 16.3% for excessive drinking to 49.3% for poor diet quality. The prevalence of cardiometabolic diseases ranged from 4.3% for diabetes to 37.3% for dyslipidemia. The prevalence of having ≥2 lifestyle risk factors was 45.2% and having ≥2 cardiometabolic diseases was 22.0%. Racial and ethnic disparities in many cardiometabolic diseases persisted but were attenuated after adjusting for social risk factors and lifestyle factors. Conclusions The prevalence of lifestyle risk factors and cardiometabolic diseases was high among US young adults and varied by race and ethnicity and social risk factors. Racial and ethnic disparities in the prevalence of cardiometabolic diseases were not fully explained by differences in social risk factors and lifestyle factors.

Informatics for your Gut: at the Interface of Nutrition, the Microbiome, and Technology

BACKGROUND

A significant portion of individuals in the United States and worldwide experience diseases related to or driven by diet. As research surrounding user-centered design and the microbiome grows, movement of the spectrum of translational science from bench to bedside for improvement of human health through nutrition becomes more accessible. In this literature survey, we examined recent literature examining informatics research at the interface of nutrition and the microbiome.

OBJECTIVES

The objective of this survey was to synthesize recent literature describing how technology is being applied to understand health at the interface of nutrition and the microbiome focusing on the perspective of the consumer.

METHODS

A survey of the literature published between January 1, 2021 and October 10, 2022 was performed using the PubMed database and resulting literature was evaluated against inclusion and exclusion criteria.

RESULTS

A total of 139 papers were retrieved and evaluated against inclusion and exclusion criteria. After evaluation, 45 papers were reviewed in depth revealing four major themes: (1) microbiome and diet, (2) usability,(3) reproducibility and rigor, and (4) precision medicine and precision nutrition.

CONCLUSIONS

A review of the relationships between current literature on technology, nutrition and the microbiome, and self-management of dietary patterns was performed. Major themes that emerged from this survey revealed exciting new horizons for consumer management of diet and disease, as well as progress towards elucidating the relationship between diet, the microbiome, and health outcomes. The survey revealed continuing interest in the study of diet-related disease and the microbiome and acknowledgement of needs for data re-use, sharing, and unbiased and rigorous measurement of the microbiome. The literature also showed trends toward enhancing the usability of digital interventions to support consumer health and home management, and consensus building around how precision medicine and precision nutrition may be applied in the future to improve human health outcomes and prevent diet-related disease.
