Understanding Available Data Sources to Estimate the Size and Distribution of Nutritionists and Registered Dietitians in the United States

Principal Investigator: Brianna Lombardi, PhD, MSW

Nutritionists and registered dietitians (RDs) are essential healthcare professionals who provide medical nutrition therapy, preventive nutrition services, and health promotion programs to address diet-related chronic diseases and improve population health outcomes. This study will compare five national data sources to understand the size and geographic distribution of the nutrition workforce in the United States, examining variations in workforce estimates by source, geography, and state regulation.
