OBJECTIVE: In this study, the researchers conducted a scoping literature review of the web-based dietary changes and physical activity-related intervention programs designed for the patients with hypertension and identified the methodologies, effectiveness, protocols, and theories, which could affect and improve existing clinical activities.
METHODS: This review followed the scoping review methodology to identify and process the peer-reviewed studies published between 2010 and 2020. The literature searches were conducted on the following electronic databases: PubMed, Web of Science, MEDLINE (Medical Literature Analysis and Retrieval System Online), ScienceDirect, Scopus, and Google Scholar. By using relevant search terms, studies were included if they offered information related to the web-based intervention tools, specifically dietary and physical activity intervention for patients with hypertension. Studies written or translated in English language and published within the date range (January 2010 to March 2020) were included.
RESULTS: Overall, 1441 articles were initially identified. The reviewers included 35 articles after removing duplicates and screening titles. Only 21 articles were assessed for full review, and 15 were kept for analysis. The researchers selected 15 web-based intervention articles published on the topic of hypertension from 7 countries. A few of these 15 web-based tools (4, 27%) included more than 3 functions and provided a lot of important information (such as appointments, health records, or viewable care). Several tools were standalone tools (11, 73%), while most of the tools supported communication intervention-related lifestyle or behavioral changes (13, 87%) and medication adherence (6, 40%). It was found that physicians (9, 60%), allied health professionals (5, 33%), and nurses (5, 33%) were the health care providers who generally used these tools for communicating with their patients. More than half of the above tools (10, 67%) were assessed by different researchers in randomized controlled trials, while 5 tools (33%) were investigated in nonrandomized studies.
CONCLUSIONS: We identified many web-based intervention programs for patients with hypertension from the literature databases. The findings indicate that numerous benefits can be derived after using a web-based dietary and physical activity intervention program for hypertension focusing on lifestyle changes. However, developers need to consider the preferences of the patients with regard to the information or the design features while developing or modifying web-based educational websites. These tools could be used for designing a patient-tailored website intervention program that is based on diet and physical activities for patients with hypertension.
METHODS: A website called D-PATH was developed, consisting of 6 learning units for managing hypertension. A 4-week program was implemented, and a pre- and post-intervention assessment was conducted to measure acceptability and changes in knowledge, attitude and practice, dietary intake, physical activity, and anthropometric status.
RESULTS: The D-PATH website was acceptable in terms of understandability, actionability and cognitive load. Knowledge, attitude and practice, and physical activity levels were improved, but no changes were noted for dietary intake and blood pressure level.
CONCLUSION: The D-PATH website was accepted and feasible for the intervention study. This study has shed light on using the website to promote behavioral change in patients with cardiometabolic risks.
METHODS: The website development involved three stages: content analysis, web development, and validation. The model of Internet Intervention was used to guide the development of the website, in addition to other learning and multimedia theories. The content was developed based on literature reviews and clinical guidelines on hypertension. Then, thirteen experts evaluated the website using Fuzzy Delphi Technique.
RESULTS: The website was successfully developed and contains six learning units. Thirteen experts rated the website based on content themes, presentation, interactivity, and instructional strategies. All experts reached a consensus that the web is acceptable to be used for nutrition education intervention.
CONCLUSION: D-PATH is a valid web-based educational tool ready to be used to help disseminate information on dietary and physical activity to manage hypertension. This web application was suitable for sharing information on dietary and physical activity recommendations for hypertension patients.
