Bio

Dr. Fretts is a cardiovascular and nutritional epidemiologist with a focus on observational and interventional research aimed at improving cardio-metabolic health in underserved and rural communities (with a focus on American Indian communities). Her work aims to work with community partners to integrate observational and interventional research to mitigate obesity-related health disparities and improve health behaviors and health outcomes. Dr. Fretts’ research primarily focuses on nutrition, food insecurity, the food environment, physical activity, obesity, fatty acids, and diabetes. She is the Principal Investigator of the Dakotas field site for the Strong Heart Study, a large cohort study of heart disease and its risk factors in 12 American Indian communities in Arizona, Oklahoma, North Dakota and South Dakota, that has been on-going since 1988. She is also Principal Investigator of a community-based diet and cooking skills intervention (randomized trial) designed to improve blood sugar control and other cardiovascular risk factors for American Indians with type 2 diabetes. In addition to her work with American Indian communities, she is involved in several on-going projects related to fatty acids, diet, diet*gene interactions, diabetes, and cardiovascular outcomes in the Cardiovascular Health Study and the Fatty Acids and Outcomes Research Consortium (FORCE) consortium.
