    Although a Dietary Approaches to Stop Hypertension (DASH) eating plan has been shown to lower blood pressure (BP) in Black adults, this intervention has not been tested in individuals who were being actively treated for hypertension. In this study, we conducted a randomized clinical trial (GoFreshRx) to test whether local groceries ordered with the assistance of a dietitian to align with the DASH diet might lower BP among Black adult residents of Boston communities with few grocery stores who were being actively treated for hypertension. Individuals whose systolic blood pressure (SBP) was 120 mmHg to <150 mmHg despite active hypertension treatment were randomized either to 12 weeks of weekly home-delivered DASH groceries with dietitian counseling or to receiving three US$500 stipends every 4 weeks. The primary outcome was research clinic-measured SBP measured at 3 months. Secondary outcomes were diastolic blood pressure (DBP) and low-density lipoprotein cholesterol (LDL-c) levels. Maintenance of health effects was assessed at 3 months after the intervention. Of 176 participants (mean age 60.1 (s.d., 11.5) years; 80.7% female), 173 were available for SBP measurement at 3 months. Mean (s.d.) baseline SBP/DBP was 130.5 (7.0)/77.8 (8.9) mmHg. At 3 months, SBP changed by -7.0 mmHg in the DASH groceries group and by -2.0 mmHg in the self-directed group (intergroup difference: -5.0 mmHg; 95% confidence interval: -8.0 to -1.9; P = 0.002). Moreover, compared to the self-directed group, 3 months of DASH groceries changed DBP by -1.8 mmHg (-3.6 to -0.1) and LDL-c by -7.0 mg dl-1 (-13.6 to -0.5). In prespecified analyses, the beneficial effects of DASH grocery delivery on SBP and DBP were partially maintained 3 months after the intervention had concluded. Nutrient-targeted grocery ordering appears to be a useful strategy to improve longer-term cardiometabolic health. ClinicalTrials.gov registration: NCT05393232 .

(2026) 2026. “Prospective Study of Breakfast Frequency and Timing and Risk of Myocardial Infarction and Coronary Artery Disease in Community-Dwelling Older Adults: The Cardiovascular Health Study.”. The Journal of Nutrition, Health & Aging 30 (5): 100825. https://doi.org/10.1016/j.jnha.2026.100825.

    OBJECTIVES: Because it is unknown whether breakfast frequency and timing are associated with long-term risk of incident myocardial infarction (MI) and coronary artery disease (CAD) among older adults, this study aimed to assess relationships between breakfast frequency/timing and MI/CAD risk among older adults and determine whether they depend on sex or cardiometabolic risk factors.

    DESIGN AND SETTING: Prospective cohort study of older American adults.

    PARTICIPANTS AND MEASUREMENTS: Weekly breakfast frequency and usual daily breakfast time were assessed by questionnaire in 4070 adults aged ≥ 65 years from the Cardiovascular Health Study who were prospectively followed for up to 26 years. Cause-specific hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated from multivariable-adjusted Cox proportional hazards models.

    RESULTS: During follow-up, 1617 CAD cases were documented (795 MI cases). Although consuming breakfast 7 days/week (85.3%) and 'breaking-fast' between 07:00 and 09:00am (72.6%) were both associated with higher education and socioeconomic status, being married, not smoking, and consuming fruits and vegetables, neither breakfast frequency nor breakfast timing was associated with risk of CAD or MI in males, females, or altogether. In pre-specified analyses, compared with participants who ate breakfast daily, those who did not eat breakfast daily had an HR for MI of 0.66 (95% CI: 0.43, 1.02) if their body mass index (BMI) was ≥30 kg/m2 and of 1.17 (0.91, 1.51) if their BMI was <30 kg/m2 (interaction p = 0.02). Compared with participants whose breakfast time was 07:00-09:00, those who broke their fast before 07:00 had an HR for CAD of 1.40 (1.02, 1.93) if they had type 2 diabetes and of 1.19 (1.03, 1.38) if they had high fasting insulin at baseline.

    CONCLUSION: Breakfast frequency and timing were not associated with either higher or lower risk of MI and CAD in these older adults. Although a priori stratification by cardiometabolic risk factors may have revealed potential trends, the findings must be confirmed in a larger study.

(2026) 2026. “Socioeconomic Correlates of Incident Heart Failure and Consequent Mortality: The All of Us Program.”. JACC. Heart Failure, 103012. https://doi.org/10.1016/j.jchf.2026.103012.

    BACKGROUND: Although socioeconomic status (SES) is a known determinant of cardiovascular disease, the independent risks of incident heart failure (HF) and consequent mortality portended by individual and neighborhood measures of SES remain less established.

    OBJECTIVES: This study sought to evaluate the prospective associations of SES with HF in adults without HF and SES with all-cause mortality in those with HF.

    METHODS: The authors identified adults from the National Institutes of Health-run All of Us Research Program (2018-present) who consented to share their electronic health records. Among 280,431 participants free of HF and 10,550 participants with prevalent HF, Cox proportional hazards models assessed associations of income, education, and Area Deprivation Index (ADI) with risks of incident HF and mortality.

    RESULTS: Over 41 ± 23 months, 6,783 of 280,431 participants developed HF. Compared with household income ≥$200,000, risk was higher for $100,000 to <$200,000 (HR: 1.29; 95% CI: 1.12-1.48), $50,000 to <$100,000 (HR: 1.82; 95% CI: 1.60-2.09), $25,000 to <$50,000 (HR: 2.24; 95% CI: 1.95-2.57), and <$25,000 (HR: 3.02; 95% CI: 2.63-3.47). Relative to college graduates, risk was higher for those with some college (HR: 1.37; 95% CI: 1.28-1.46), General Educational Development (HR: 1.46; 95% CI: 1.36-1.58), and less than high school (HR: 1.40; 95% CI: 1.26-1.55). Compared with the least deprived tertile of ADI, risk was higher in the middle tertile (HR: 1.21; 95% CI: 1.14-1.29) and the most deprived tertile (HR: 1.18; 95% CI: 1.11-1.26). Non-White participants and residents of the most deprived ADI tertiles experienced less benefit from higher education. Among those with prevalent HF, each $10,000 increase in income was associated with 3% lower all-cause mortality.

    CONCLUSIONS: Lower income, education, and high neighborhood deprivation independently associate with incident HF, whereas only income was associated with mortality. Higher education was less protective in non-White participants and individuals residing in deprived neighborhoods. Addressing these disparities is essential to reducing HF burden and consequent mortality.

Journal of Hypertension 44 (5): 763-70. https://doi.org/10.1097/HJH.0000000000004210.

    BACKGROUND: In observational studies, blood pressure (BP) variability has been independently associated with adverse cardiovascular disease outcomes. The Dietary Approaches to Stop Hypertension (DASH) diet and sodium reduction lower BP and cardiovascular risk, but their effects on BP variability (BPV) are uncertain.

    METHODS: This study assessed the effects of dietary patterns (DASH vs. Control) and sodium intake (higher vs. lower) on BPV, using both office and 24-h ambulatory BP measurements in the DASH and DASH-Sodium trials. In primary analyses, week-to-week office BPV and 24-h ambulatory BPV were quantified using variation independent of the mean (VIM). Between-group comparisons were performed using t-tests; interactive effects between dietary patterns and sodium intake were assessed using multivariate linear regression models.

    RESULTS: In pooled analyses of both trials, there was no difference in week-to-week systolic BPV (difference in systolic VIM: 0.49, 95% CI -0.05-1.03) or 24-h systolic BPV (difference in systolic VIM: 0.37, 95% CI -0.13-0.87) between the DASH and Control diet groups. In the DASH-Sodium trial, VIM at higher and lower sodium levels did not differ (e.g. difference in VIM for week-to-week systolic BP: 0.31, 95% CI -0.10-0.72). No significant combined or interactive effects of diet and sodium level on BPV were observed.

    CONCLUSION: While the DASH diet and reduced sodium intake lower absolute BP levels, these dietary interventions do not significantly affect BPV. These findings suggest that the BP-related benefits of the DASH diet and sodium reduction likely result from reducing absolute BP rather than reducing BPV.
