An integrated community-based approach to hypertension
Hypertension is one of the most significant chronic health challenges facing older adults, affecting two-thirds of Americans over age 60 and contributing to cardiovascular disease, cognitive decline and loss of independence. Despite its prevalence, this population has the lowest hypertension control rates, increasing strain on families, health systems and community resources. While the Dietary Approaches to Stop Hypertension (DASH) diet is a proven non-pharmacological strategy for lowering blood pressure, few models successfully translate it into sustainable, community-based programs for older adults.
DASH-Plus, funded by USDA and delivered through University of Maryland Extension, responds to this need with a comprehensive, theory-driven hypertension management program designed specifically for community-dwelling older adults. From 2022–2025, DASH-Plus established a statewide platform integrating research, education and community partnerships to support long-term blood pressure management.
During its initial implementation in 2022–2023, the program enrolled 211 adults aged 60+ across 16 senior centers using an experimental design. Based on strong early results, DASH-Plus expanded statewide, ultimately reaching approximately 400 hypertensive older adults. The program combines three synergistic components: a five‑week DASH-based education series, produce delivery partnerships that increase access to fresh fruits and vegetables and self-measured blood pressure monitoring stations within senior centers.
Preliminary results demonstrate meaningful improvements. In the randomized trial, recommended fruit intake increased from 56% at baseline to 81% after the education sessions, with similar gains in vegetable and fish consumption. Participants also experienced significant reductions in systolic and diastolic blood pressure, changes not observed in the control group. In 2024, delayed-intervention evaluations showed statistically significant increases in participants’ hypertension-related knowledge, confidence and readiness to adopt heart-healthy behaviors.
DASH-Plus offers a scalable, sustainable community model that enhances dietary habits, strengthens self-management skills, and reduces chronic disease burden. By improving health outcomes and supporting local food systems, it delivers measurable benefits to individuals, families and Maryland communities while informing national efforts to promote healthy aging.
