“Relating Families’ History of Food Pantry Use to Children’s Obesity Status”

Project Leader:

Mentor(s):                

Pearl McElfish, PhD

Rodolfo Nayga, PhD

Dr. Long will look deeper into the barriers to distribution of healthy foods in food pantries and how food from these pantries fits into the overall diets of families that visit them. The idea behind the project is that many food insecure children are often overweight or obese because the diets of food insecure families do not fit nutritional guidelines and pantries struggle to provide sufficient quantities of nutritious food. The long-term goal is to develop and test strategies using the data gathered from food pantries in northwest Arkansas to reduce the rates of obesity among food insecure children.

Affiliated Project 2

“Type 1 Diabetes Summer Camp Effects on Energy Expenditure and Blood Glucose Control”

Project Leader:      

Jon Oden, MD
Associate Professor
Department of Pediatrics, College of Medicine
University of Arkansas for Medical Sciences

Dr. Oden will be looking at data collected (HbA1c, blood glucose values, insulin doses, pre- and post-camp body weight, carbohydrate intake) through the 5-day camp experience for each of the campers enrolled in the Camp Aldersgate Diabetes Summer Camp. Data will be analyzed to evaluate the effect of camp education and activity on long-term diabetes control (HbA1c changes over the year in campers vs those not involved in camp), the effect of specific carbohydrate intake on weight changes documented during camp, and improvements in first versus last day blood sugars and insulin doses. Also, families are asked to recall HbA1c values at their last visit with the Diabetes Provider. Using this data and confirming actual values with Arkansas Children’s medical database or through the camper’s primary Endocrinologist, we can correlate the family’s perception of diabetes control with reality.

Affiliated Project 3

“Establishing the Presence of Mitochondrial Dysfunction and Oxidative Stress in Childhood Obesity”

Project Leader:      

Shannon Rose, PhD
Assistant Professor
Department of Pediatrics, College of Medicine
University of Arkansas for Medical Sciences

While mounting evidence supports a role for dysfunctional mitochondria in obesity in adults, there is a major research gap regarding the status of mitochondrial function in childhood obesity and its role in the development of type 2 diabetes in children. Dr. Rose will study whether circulating cell bioenergetics are impaired and whether plasma glutathione-mediated redox/antioxidant capacity is decreased in obese insulin resistant children as compared to normal weight and obese insulin sensitive children. She will also examine whether resting energy expenditure and whole body fatty acid oxidation are decreased in obese insulin resistant as compared to lean and obese insulin sensitive children and whether resting energy expenditure and whole body fatty acid oxidation are correlated with circulating cell bioenergetics.
