Comparing the activity data with how urban/rural the residential area was showed that people in urban areas had lower
MET-hours values than those in rural and urban-rural areas.Associations of neighborhood walkability attributes with
commuting by walking have been confirmed in Australia [14].With respect to environment, physical activity has been
associated with transportation, population density, recreational activities, and connectivity [25]. In this study, although the time spent walking to work among participants in urban areas was a mean 24 (SD 25.3) minutes, it was only a mean 7.4 (SD 25.3) minutes in rural areas. Time spent commuting by car or public transportation has been shown to differ significantly between urban and rural residents. That people in urban areas had higher physical activity related to transportation than did those living in rural areas is consistent with data from the National Health and Nutrition Examination Survey (NHANES) [26].
