This project provided supplemental funds for a study originally funded by the National Cancer Institute (NCI) focused on obesity and the built environment. This Obesity and the Built Environment (OBE) supplemental grant added to a larger previously funded OBE grant that examined the feasibility of obtaining adolescent self-defined neighborhood boundaries via a mapping exercise, test the practicability of having adolescents complete travel diaries to document their travel and utilization behavior, and elicit factors that are important to adolescents in determining utilization, route preference and neighborhood boundaries. This supplement complemented the OBE funded study by adding objective data from a built environment assessment tool (the Physical Activity Resource Assessment (PARA) instrument) and a nutrition environment assessment tool (the Nutrition Environment Measurement Study (NEMS)) to answer the question, “how does quality (objectively measured) and availability of specific amenities or food variety affect physical activity and eating behavior in adolescents?”
