  1. *P < 0.1, **P < 0.05, ***P < 0.01
  2. a Models 4, 5, 6 adjust for age, sex, income adequacy, weight status, general health status, weight concern, ALE measure, and city of residence. Time-weighted ratio of fast food stores are computed in buffer of activity locations with radii of 500 m, 1 km, and 1.5 km in Models 4, 5, 6 respectively
  3. b Incident rate ratios (IRRs) represent difference in expected weekly fast food consumption frequency per one-unit increase in a predictor variable
  4. c The temporal weight is the proportion of time spent in each of the activity locations relative to the total time spent in all activity locations of an individual
