A Scoping Review of the Application of Mobile Health inNutrition Education for Patients with Chronic Diseases

Aim: To conduct a scoping review of the application of mobile health in nutrition education for patients with chronic diseases, and to clarify the intervention carriers, intervention elements, outcome indicators, and effects, to provide a reference for follow-up related research.Design: A scoping review was conducted systematically following the methodological framework of Arksey and O"Malley: identify relevant studies; select studies based on predefined criteria; extract data; and analyze, summarize, and report results.The Preferred Reporting Items for Systematic Reviews and Metaanalyses for Scoping Reviews (PRISMA-ScR) was used to optimize reporting and to enhance fidelity.Ethical approval was not needed for this review of existing literature.Methods： Following the scoping methodology framework created by Arksey and O'Malley, PubMed, Cochrane Library, CINAHL, Embase, Web of Science, CNKI, Wanfang Database, VIP Chinese Scientific and Technical Journals Database, and China Biomedical Literature Database were systematically searched from inception to April 1, 2025.The literature was screened in strict accordance with the inclusion and exclusion criteria, and the literature information was extracted and summarized.Results: A total of 18 articles were included.The primary mHealth channels for nutrition education include social media, nutrition knowledge apps, online platforms, and digital nutrition education games.The main elements of the intervention included the formation of nutrition intervention teams, provision of nutrition and health knowledge, nutrition monitoring, interactive communication and counseling, peer support, testing, establishment of competitive incentives, and integration of nutrition education courses with mobile health technology.Conclusion： The application of mHealth in nutrition education is a key driver of continued innovation and development in health education.Nutrition education for chronically ill patients is a long-term process, and mobile health apps can continuously track changes in patients' eating behaviors and health indicators.When developing nutrition education games and mobile health platforms, it is necessary to select appropriate user groups, prioritize multidisciplinary teamwork, and conduct theory-based research on intervention programs to enhance the effectiveness and user adaptability of nutrition education content.In the future, mobile health intervention technology can be organically integrated with traditional nutrition education activities, complementing each other to enhance the effectiveness of the intervention.
