Summary
A digital health intervention improved medication adherence and blood pressure (BP) control in older adults with hypertension. Further research is needed to confirm these positive effects in larger, longer trials.
Area of Science:
- Digital Health
- Cardiovascular Health
- Behavioral Science
Background:
- Hypertension management relies on medication, diet, physical activity, and BP monitoring, with adherence being crucial.
- Evidence is limited on digital interventions' effectiveness in improving adherence to healthy behaviors for hypertensive patients.
Purpose of the Study:
- To develop a digital health behavioral intervention for hypertensive patients using an intelligent health promotion system and WeChat.
- To assess the intervention's efficacy in controlling BP and enhancing adherence to healthy behaviors based on the Behavior Change Wheel (BCW) theory and Digital Micro-Intervention Care (DMIC) model.
Main Methods:
- A 2-arm randomized trial involved 68 adults over 60 with hypertension, assigned 1:1 to control or experimental groups.
- The intervention included digital education materials, BCW techniques, DMIC model, and a 12-week WeChat-based program for the experimental group.
- Primary outcomes were BP and adherence indicators, analyzed using SPSS with t-tests and chi-square tests (P<.05 significance).
Main Results:
- The experimental group showed significant improvements in systolic BP, exercise duration, medication adherence, BP monitoring frequency, and learning performance.
- Both groups achieved weight reduction; diet quality and subendocardial viability ratio also improved significantly in both.
- No statistically significant changes were observed in other health outcomes.
Conclusions:
- The digital intervention shows potential for improving specific health outcomes and behavior adherence in older hypertensive adults.
- Larger-scale, longer-term trials are required to validate the intervention's effectiveness.

01:28Hypertension I: Introduction
Hypertension is a widespread, long-term medical condition where blood pressure in the arteries remains elevated. It is characterized by systolic blood pressure readings of 130 mm Hg or above or diastolic blood pressure (DBP) readings of 80 mm Hg or higher. Unmanaged hypertension poses significant health risks, making the distinction between primary (or essential) hypertension and secondary hypertension crucial, as their management and implications vary.Primary HypertensionPrimary hypertension,...

Multiple classes of antihypertensive medications are employed in treating hypertension. The most commonly recommended first-line treatments include:Thiazide Diuretics, such as chlorthalidone, increase sodium and water excretion from the body, reducing blood volume and blood pressure.Angiotensin-converting enzyme inhibitors, like lisinopril, block the conversion of angiotensin I to II, a potent vasoconstrictor lowering blood pressure.Angiotensin II Receptor Blockers (ARBs) prevent angiotensin II...
01:23Hypertension V: Nursing Management
The nursing management of hypertension involves accurately assessing symptoms, making a comprehensive nursing diagnosis, collaborating with patients to set goals, and implementing targeted interventions to mitigate the condition's impact and improve patient well-being.Comprehensive AssessmentThe initial step in nursing care for hypertension involves a thorough patient assessment. It includes evaluating symptoms such as headaches, dizziness, blurred vision, and previous hypertension episodes.
