TEAN: Evaluating the Relationship Between Physical Activity, Diet, Weight, and the Neighborhood Environment for Adolescents

Led by Dr. Jim Sallis, the primary goal of the project is to examine the association of built environment and food environment variables with behavioral and weight-related outcomes in adolescents aged 12 to 16 years.  The forty-eight neighborhoods in King County, WA and Baltimore-Washington, DC being studied were selected based on walkability levels (e.g., combination of street connectivity, residential density, land use mix, retail floor area ratio) and median income levels. Study researchers examined and created formulas to measure walkability, pedestrian infrastructure, public recreation space, and nutrition environment quality. Researchers also examined crime and weather patterns; psychosocial variables; parent support; and perceived neighborhood, school, and home environments. Individual data was collected using accelerometers, GPS units, surveys, and food recalls.  Overall, the study is evaluating the ability of a research model to explain the variation in physical activity levels, sedentary behavior, dietary patterns, and weight among adolescents, with an emphasis on neighborhood environment.  



Established in 2009, the University of Pennsylvania's Center for Health Behavior Research is an institution-wide collaborative effort, dedicated to conducting health behavior research, fostering advances in measurement of health behaviors, advancing the use of health behavior theory, and promoting collaboration among faculty, fellows and students.
