Mobile App-Based Interventions to Support Maternal Roles in Child Nutrition and Development: A Scoping Review

Background: Early childhood is crucial for long-term health, growth, and development, with mothers playing a central role in nutrition and stimulation. Mobile health (mHealth) technologies have potential to support maternal practices through real-time, context-specific guidance. However, evidence on how mobile applications specifically enhance maternal roles in child nutrition and development is limited and fragmented. Objective: This scoping review aimed to map and synthesize evidence on mobile app-based interventions that support maternal roles in child nutrition and development. Methods: Following Arksey and O'Malley's framework and the PRISMA-ScR checklist, we systematically searched PubMed, Scopus, Web of Science, CINAHL, PsycINFO, and grey literature for studies published between 2013 and 2025. Eligible studies evaluated mHealth interventions targeting maternal behaviors for children under five. Data were extracted and analyzed thematically. Results: Twenty-five studies met the inclusion criteria. Most interventions addressed breastfeeding, complementary feeding, and developmental stimulation. Common app features included educational modules, growth monitoring, real-time guidance, and peer support. Positive outcomes were observed in breastfeeding practices, child growth, and developmental milestones. Key barriers included low digital literacy and limited access to technology, particularly in marginalized populations. Conclusion: mHealth applications show promise in supporting maternal roles and improving child nutrition and development outcomes. Future research should focus on digital equity, broader accessibility, and the cost-effectiveness and scalability of these interventions, especially in underserved settings.
