Clinical/Research Interests:

Dr. Sisson conducts her research in the Behavioral Nutrition and Physical Activity Laboratory in the Department of Nutritional Sciences at the University of Oklahoma Health Sciences Center. Research in the lab focuses on physical activity and sedentary behavior epidemiology and related risk behaviors such as the consumption of poor quality food. Other research interests include the influence of the physical and social environment on food consumption and physical activity behaviors and the impact of sedentary lifestyle on chronic diseases such as obesity as well as intervention development and evaluation to combat sedentary lifestyle and poor food choices. Children and disadvantaged populations are of particular interest.

Dr. Sisson's Video

Could your child's daycare diet be leaving him full, but malnourished? 

Dr. Susan Sisson, researcher at the College of Allied Health Department of Nutritional Sciences says the answer is “Yes.” 

Their study found many Oklahoma child care centers are providing plenty of calories in their meals, but not necessarily enough of the right nutrients for growing minds and bodies. 

And that may also contribute to childhood obesity.
