Diet, Physical Activity, and Sleep Habits Study– Closed to Enrollment
The Diet, Physical Activity, and Sleep Habits Study evaluates the diet, physical activity, and sleep habits of young adults. Over the course of one week, participants wear an armband day and night and answer a daily survey about their typical activities. On three of these days, participants complete food records of all foods and drinks consumed. Participants attend one 60-minute session at the beginning of the week and one 30-minute session at the end. Both men and women between the ages of 18-35 years who are working and/or taking classes and who are able to engage in physical activity are eligible for this study. A $25 gift card will be given to participants for their involvement

Dietary Assessment Study – Closed to Enrollment
Currently, there is no gold standard or single method of dietary assessment that is applicable for all nutrition research questions, as the purpose, population of interest, and resources available in any investigation impact the method of assessment that can be implemented. This study is validating a passive image-assisted dietary assessment method using images taken by Sony Smarteyeglass to identify food items and estimate portion sizes.

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.
