Research Interest

Dr. Hanson’s research primarily focuses on food security and public policies affecting low-income families with children in the U.S.  Currently, she is co-PI of Farm Fresh Foods for Healthy Kids (F3HK): an innovative community supported agriculture (CSA) intervention to prevent childhood obesity and strengthen local agricultural economies.  F3HK is a randomized controlled intervention trial to examine whether cost-offset (subsidized) CSA coupled with tailored nutrition education and cooking tools improves dietary intake among children and parents and increases food security in low-income households.

Dr. Hanson also is collaborating on an assessment of the Farmers’ Market Nutrition Program (FMNP) to understand if the education component influences shoppers’ knowledge of, and confidence in, selecting and preparing fresh produce, as well as whether in-market cooking demonstrations are associated with increased sales of the featured produce.

Dr. Hanson recently completed a mixed-methods study of the circumstances of, and coping strategies in, households with food insecure children and contrasted them with households that face substantial risk of food insecurity yet in which children are food secure.  Results from this study were published in the Journal of Poverty.  She also recently completed a systematic review of the association between food insecurity and dietary quality among U.S. adults and children that was published in the American Journal of Clinical Nutrition.
