Dr. Folta’s research interests focus on public health nutrition, or the utilization of community-based strategies for improving dietary intake, physical activity, and body composition. She has particular expertise in behavioral psychology, communications, and qualitative methods. A major line of Dr. Folta’s research involves community-based interventions to improve heart health among women. A second area of research includes behavioral strategies to improve health and well-being among older adults, particularly through the development of physical activity interventions. Dr. Folta’s third line of research involves community-based interventions for obesity prevention among children. These studies, in which theory-based communications strategies were a major component, are notable for the use of the eco-social model in which multiple levels (individual-organization-community-policy) are targeted.
