Healthy Weight

The Section on Healthy Weight is committed to preventing and reducing childhood obesity in eastern North Carolina and across the state and nation by conducting collaborative research studies and projects. For more information please visit the Pediatric Healthy Weight Research and Treatment Center (PHWRTC) website

Open Clinical Trials

Pediatric Health Weight Database
A retrospective longitudinal cohort study of obese children in eastern North Carolina. With the goal of understanding obesity related illness and the effect of our treatment approach on primary and secondary health-related outcomes. Specifically, the study will track of children's physiological and psychosocial changes over time.

MATCH (Motivating Adolescents with Technology to CHOOSE Health™)
MATCH is a middle school-based, childhood obesity intervention that uses an interdisciplinary approach to student wellness. The program combines a nutrition, physical activity and technology curriculum with a web-based resource system to meet educational and wellness objectives simultaneously. MATCH teaches students how the health choices they make will impact their future. The current research project is to evaluate the impact of MATCH on weight status, fitness, and lifestyle behaviors and study its feasibility and effectiveness when expanded to selected schools in eastern NC (eNC).

Benzoic acid in beverages: establishing a link between urinary metabolites, metabolic dysregulation and weight loss failure
A study of overweight and obese, healthy, young adults to determine if benzoic acid (aka sodium benzoate or potassium benzoate), a chemical commonly added to certain foods and drinks as a preservative, slows a person’s metabolism and makes them more likely to gain or retain weight.
