The Powers Lab is focused on improving nutrition in children with cystic fibrosis, obesity and type 1 diabetes. In children with CF, nutrition interventions that incorporate behavioral therapies have shown promise in increasing energy intake. Of particular interest in the study of obesity are low-income African-American children, an understudied group. The lab also is looking for specific behavioral management strategies at mealtimes to improve children’s glycemic control to help patients with type 1 diabetes.
