摘要

Malnutrition remains a pressing public health concern in Nigeria, driven by limited dietary awareness and a lack of culturally relevant nutrition tools. The current study introduces NutriNG, a conceptual mobile application prototype designed to promote healthier eating through nutrition tracking and persuasive communication. Guided by the COMTECH framework and Design Science Research, NutriNG integrates a Nigerian meal database, nutrient breakdowns, and tailored dietary advice. Persuasive strategies, including message framing, nudging, feedback, and cultural resonance, were embedded to influence dietary decisions. For example, framing techniques emphasized the benefits of protein-rich meals, nudges promoted vegetable inclusion through visual cues, and feedback mechanisms highlighted progress toward balanced intake. All meals were reviewed by a certified dietician to ensure nutritional and cultural relevance. A cognitive walkthrough using diverse user personas revealed that while tech-savvy individuals navigated the interface with ease, others required clearer instructions and simplified layouts. These findings underscore the importance of inclusive design and strategic communication. As a feasibility prototype, NutriNG offers a foundation for future development and testing, with potential to inform scalable nutrition interventions in similar contexts.
