Within-subject analyses
Fig 2 showed that on days when a participant moved through a greater life-space area more physical activity was detected. Table 3 shows the results of the GEE models. Compared to a day when a participant stayed within their own neighborhood, staying inside the home was associated with lower physical activity and going to the town area was associated with greater physical activity in all measures. However, when moving beyond the town, step count and moderate activity time were not different from moving in the neighborhood only. Yet, low activity time was statistically significantly greater and sedentary time significantly lower when moving beyond the town. When the GEE models were further adjusted for age, sex, walking difficulty and car driving, differences in physical activity associated with the life-space areas were attenuated but the overall trend remained statistically significant (p < .001). Compared to a day when a participant stayed inside the home, going outside was associated with significantly greater physical activity (p.033), except for low activity time (p = .091).
