Abstract
BACKGROUND: Activity spaces (AS), captured using GPS tracking devices, are measures of dynamic exposure to the built environment (BE). METHODS: Seven days of Global Positioning Systems (GPS) tracking data were obtained for 433 adult participants in the Seattle Obesity Study (SOS II). Heights and weights were measured. Dietary intakes from a food frequency questionnaire were used to calculate Healthy Eating Index (HEI 2010) scores. Linear regression analyses examined associations between AS measures: daily route length, convex hull, and radius of gyration, and diet quality and health outcomes, adjusting for covariates. RESULTS: AS measures did not vary by age, gender, race/ethnicity, or socioeconomic status. AS measures were not associated with diet quality or with self-reported obesity or diabetes. One AS measure, route length (in miles), was associated with being employed, living in the suburbs, and with distance and time commuting to work. CONCLUSION: Spatial mobility studies based on GPS tracking of environmental exposure need to demonstrate a link to relevant health outcomes.
