If you are interested in participating in a research study that is open for enrollment, please call us at 865-974-0752 or e-mail us at
Television and Liking of Food Study – Closed to Enrollment
The Television and Liking of Food study investigates the effect of watching TV on liking of food. Eligibility for this study includes an age between 18-35 years, a healthy weight, non-smoker, normally eat breakfast, and are free from dietary restrictions. Participants will engage in five appointments, four of which involve lunch sessions. Compensation for participants’ time includes 4 free meals and a payment of $25.
Fruit Juice Portion Size Impact on Fruit Juice Consumption and Overall Energy Intake in Preschoolers – Closed to Enrollment
Environmental factors such as portion size and caloric content of beverages are linked to energy intake, and may play a role in the development of weight problems. This study will investigate whether beverage type (caloric [100% fruit juice] vs. non-caloric) and beverage portion size (6 oz vs. 12 oz) impact on energy intake during a snack in preschool-aged children.
Growing Healthy! – Closed to Enrollment
Growing Healthy is a pilot study investigating the efficacy and cost-effectiveness of the Prevention Plus guidelines for the treatment of childhood obesity. The program is being implemented with overweight children (4-10 years old) and their primary caretaker in primary care settings in East Tennessee. If your child attends Knoxville Pediatric Associates, Pediatric Clinic, Oak Ridge Pediatric Clinic or Cherokee Health Centers ask your pediatrician about this free program.
Snack Food Impact Study – Closed to Enrollment
Package unit size of food may indirectly influence food intake by impacting the accuracy of consumption monitoring, and individual characteristics, such as weight status and dietary restraint, may moderate the degree of occurrence and accuracy of consumption monitoring. A better understanding of the relationship between package unit size, particularly food packaged in single serving sizes, and food intake will help nutrition professionals determine if this is an effective tool to assist with food intake reduction and if so, to which individuals this dietary tool can best be applied. If you are between the ages of 18 and 35, you may be eligible.
Active Video Gaming Compared to Unstructured, Outdoor Play in Children: Measurements of Estimated Energy Expenditure and Measured Percent Time in Moderate-to-Vigorous Physical Activity – Closed to Enrollment
The increasing use of sedentary screen-based activities (SBAs) has been most recently blamed for children and adolescents’ lack of engagement in physical activity (PA). One modification to sedentary videogames that may increase PA in children is to alter sedentary videogames so that the videogames actually provide an option to engage in PA, rather than to be sedentary. Previous studies investigating active videogames (AVG) have not investigated the energy expenditure of these games as compared to energy expenditure in free-living outdoor play. Thus, the purpose of the proposed study is to determine whether a greater energy is expended during AVG play compared to free-living, outdoor play in children aged 5 to 8 years.
Dietary Variety and Course Sequence on Fruit Intake in Preschool-aged Children – Closed to Enrollment
Environmental factors, such as portion size and energy density, can have considerable impact on energy intake, even in young children. Further research should be done on other environment factors such as dietary variety and course sequence. This study looks to investigate the influence of dietary variety (food differing in color, shape or size) and course sequence (serving food in an eating bout in multiple courses, such as a first and second course)on eating fruit during a snack in preschool-aged children.
