      BACKGROUND: Uncontrolled hypertension is a significant public health problem in the U.S. with about one half of people able to keep blood pressure (BP) under control. Uncontrolled hypertension leads to increased risk of stroke, heart attack, and death. Furthermore, the social and economic costs of poor hypertension control are staggering. People living with hypertension can benefit from additional educational outreach and support. METHODS: This randomized trial conducted at two Community Health Centers (CHCs) in Massachusetts assessed the effect of community health workers (CHWs) assisting patients with hypertension. In addition to the support provided by CHWs, the study uses video narratives from patients who have worked to control their BP through diet, exercise, and better medication adherence. Participants enrolled in the study were randomly assigned to immediate intervention (I) by CHWs or a delayed intervention (DI) (4 to 6months later). Each participant was asked to meet with the CHW 5 times (twice in person and three times telephonically). Study outcomes include systolic and diastolic BP, diet, exercise, and body mass index. CONCLUSION: CHWs working directly with patients, using multiple approaches to support patient self-management, can be effective agents to support change in chronic illness management. Moreover, having culturally appropriate tools, such as narratives available through videos, can be an important, cost effective aid to CHWs. Recruitment and intervention delivery within a busy CHC environment required adaptation of the study design and protocols for staff supervision, data collection and intervention delivery and lessons learned are presented.

      Objective: To assess patients’ knowledge about hypertension and its association with heart healthy lifestyle practices and medication adherence. Methods: We conducted a cross sectional survey of 385 adults with hypertension treated at 2 primary care clinics in Baltimore, Maryland, USA. We used an 11-item measure to assess hypertension knowledge and obtained self-reports on dietary changes, engagement in aerobic exercise and medication adherence. Results: Approximately 85% of patients properly identified high blood pressure, but more than two-thirds were unaware that hypertension lasts a lifetime once diagnosed; one-third were unaware that hypertension could lead to renal disease. Patients with low hypertension knowledge were less likely to reduce their salt intake (OR=0.44 [95% CI: 0.24-0.72]) and eat less to lose weight (OR=0.48 [95% CI: 0.26-0.87]) than patients with high hypertension knowledge. Conclusion: In general, patients were knowledgeable about hypertension, but most were unaware that hypertension is a lifelong condition and could lead to kidney disease. High knowledge of hypertension was associated with healthy lifestyle practices including eating less to lose weight and dietary salt reduction. Practice Implications: Intensifying education strategies to improve patients’ knowledge of hypertension may enhance their engagement in heart healthy lifestyle practices for optimal blood pressure control.
