Table 2 shows that participants moving beyond the neighborhood more frequently reached higher step counts, greater moderate activity and lesser sedentary time. After adjustment for accelerometer wear time, age, sex, walking difficulty, and monthly car driving the group differences were somewhat attenuated, and for sedentary behavior the associations did not remain statistically significant.Fig 1 shows that nearly all participants (94%) reached the town area at least once in the assessment week, but the majority of them on multiple days of the week. Eighteen percent of the participants stayed within the home on at least one day. All physical activity measures showed large within-subject variation. Larger within-subject variation in life-space area was associated with larger variation in step counts (Rs = -.35, p < .001) and moderate activity time (Rs = -.28, p <.001). There was no association between within-subject variation in life-space area and the variation in low activity time (Rs = -.11, p = .139) or sedentary time (Rs = .11, p = .130).
