Nutrition and Health Disparities Implementation Working Group

This working group seeks to advance NIH research to understand the interactions between diet, nutritional status, the environment, and biological and behavioral processes, and how they contribute to health disparities. It will also encourage research on how to prevent and treat nutrition-related diseases and reduce health inequities. Because “nutrition and health disparities” is a cross-cutting theme of the Strategic Plan for Nutrition Research, the workgroup will collaborate with the other IWGs to support nutrition and health disparities research. These activities will stimulate the development of research priorities that elucidate how diversity of all kinds — race, ethnicity, socioeconomic status, disability, sex, gender, gender identity, or geography — influences nutrition and health interrelationships.

The Nutrition Health Disparities Research Framework was adapted from the NIMHD Minority Health and Health Disparities Research Framework. The framework highlights multiple factors and their intersection that are relevant to understanding and addressing nutrition-related health disparities. Our definition of health disparities includes race/ethnicity, low socioeconomic status, rural, sexual/gender, and minority populations. Additionally, other fundamental characteristics such as sex/gender, disability, and geographic region are included in the framework. For more information about the NIMHD Minority Health and Health Disparities Research Framework see We welcome your comments on the Nutrition Health Disparities Research Framework.
