Achieving optimal cognitive, developmental, and growth outcomes for all children is a fundamental goal of pediatric health care providers, yet barriers such as food insecurity and social determinants of health hinder progress for many. Registered dietitian nutritionists play a pivotal role in interprofessional teams by addressing pediatric malnutrition and identifying health care disparities. The application of the Malnutrition Care Score framework in pediatric populations offers significant potential to enhance early malnutrition detection, enabling timely, targeted nutritional interventions critical for healthy development and growth. Furthermore, the Malnutrition Care Score framework advances health equity by promoting universal access to comprehensive malnutrition care, irrespective of socioeconomic status, geographic location, or care setting. To achieve meaningful improvements in pediatric nutrition, support for widespread Malnutrition Care Score implementation from institutions, policy makers, and professional organizations is essential. Ultimately, ensuring that every child receives high-quality, evidence-based nutrition care establishes a foundation for improved health outcomes across the lifespan.
