Leslie A. Lytle, PhD
Leslie Lytle is a professor in the Department of Health Behavior.
Her research focuses on the health promotion of youth and young adults, particularly preventing obesity and promoting healthful diet and physical activity through school, family and environmental approaches. She has been developing, implementing and evaluating behavior-change interventions for more than 25 years.
Dr. Lytle has been a principal investigator on several large National Institutes of Health (NIH) studies, including CATCH (NHLBI), TEENS (NCI), TAAG (NHLBI), IDEA (NCI), ECHO (NHLBI) and CHOICES (NHLBI).
She chairs the Steering Committee for the EARLY trials, a consortium of seven universities that are testing technology-based interventions to reduce weight gain in young adults at risk for obesity; her CHOICES study is one of the trials. In addition to obesity-related health behaviors in youth/young adults, she has also studied sleep-, tobacco- and alcohol-related behaviors.
