Association between daily physical activity and neighborhood environments

<p><b>OBJECTIVE</b>Previous studies on the association between physical activity (PA) and neighborhood environments (NE) focused on either objectively measuring the NE or the residents' perception of NE. Here, we investigate which actual or perceived NE is associated with residents' PA in Japan.</p><p><b>METHODS</b>Two regions with an objectively assessed high and low residential density, land use mix-diversity, and street connectivity, respectively, were identified in one city. The subjects were selected using a stratified random sampling method by sex and age in each region. The NE of the subjects was objectively measured using the Geographic Information System (GIS), and the subjects' perception of the NE was assessed using a questionnaire. The daily total number of walking steps was measured with an accelerometer, and walking and cycling time were assessed by a questionnaire.</p><p><b>RESULTS</b>For the female subjects, the mean cycling time, subjectively assessed as a means of transport, was significantly longer in the group with a high GIS score for the number of land use types, while the score for total number of walking steps was significantly higher among those who were aware of places to walk to, and cycling time for transport was longer for those who perceived an accessibility to post offices, banks/credit unions, gymnasiums/fitness facilities, and amusement facilities in their neighborhood. For the male subjects, the score for walking time for leisure was longer for those who perceived aesthetics and an accessibility to parks, and the score for total walking steps was significantly higher for those who perceived an accessibility to bookstores or rental video stores in their neighborhood.</p><p><b>CONCLUSIONS</b>The results to this study demonstrate that daily PA was high among female subjects living in a NE with land use mix-diversity, and who had an awareness of places to walk to and the accessibility to facilities for daily necessities in their neighborhood. For male subjects, daily PA was high among those who perceived the aesthetics of and accessibility to facilities for pleasure in their neighborhood. Further research is needed to determine the association between PA and NE on the basis of sex differences.</p>

Association between residents' perception of the neighborhood's environments and walking time in objectively different regions

<p><b>OBJECTIVE</b>The purpose of this study is to delineate the association between residents' perception of the neighborhood's environments and walking time in objectively different regions in Japan.</p><p><b>METHODS</b>Two regions were selected as high and low walkable regions on the basis of differences in their residential density, mixed land use and street connectivity. The subjects in this study were participants in a health promotion program focused on walking sponsored by local governments. A questionnaire was sent to the participants asking about how their perception of the neighborhood's environment related to walking, and the time spent walking per week. There were 237 residents from the high walkable region and 195 from the low walkable region who completed the study survey.</p><p><b>RESULTS</b>The high walkable region had a larger residential density, a high mixed land use and a higher street connectivity than the low walkable region. Walking time, and the scores of the perception of the neighborhood's environment for the high walkable region residents were significantly higher than those for the low walkable region residents. Thus, residents' perception of the neighborhood's environment generally reflected the actual physical environmental characteristics. Residents in the high walkable region whose scores for accessibility and aesthetics were high, spent significantly more walking time. Residents in the low walkable region whose scores for accessibility, safety, convenience and aesthetics were high, spent significantly more walking time.</p><p><b>CONCLUSION</b>The study results suggested that the neighborhood's environment may influence daily walking time. The perceptions of the neighborhood's environmental factors that correlate with walking times differ between the different regional physical environments. Therefore, to promote physical activity, the consideration of environmental factors unique to residents' neighborhood's environments is needed.</p>

Association between Residents\rq Perception of the Neighborhood\rqs Environments and Walking Time in Objectively Different Regions

Objective: The purpose of this study is to delineate the association between residents’ perception of the neighborhood’s environments and walking time in objectively different regions in Japan. Methods: Two regions were selected as high and low walkable regions on the basis of differences in their residential density, mixed land use and street connectivity. The subjects in this study were participants in a health promotion program focused on walking sponsored by local governments. A questionnaire was sent to the participants asking about how their perception of the neighborhood’s environment related to walking, and the time spent walking per week. There were 237 residents from the high walkable region and 195 from the low walkable region who completed the study survey. Results: The high walkable region had a larger residential density, a high mixed land use and a higher street connectivity than the low walkable region. Walking time, and the scores of the perception of the neighborhood’s environment for the high walkable region residents were significantly higher than those for the low walkable region residents. Thus, residents’ perception of the neighborhood’s environment generally reflected the actual physical environmental characteristics. Residents in the high walkable region whose scores for accessibility and aesthetics were high, spent significantly more walking time. Residents in the low walkable region whose scores for accessibility, safety, convenience and aesthetics were high, spent significantly more walking time. Conclusion: The study results suggested that the neighborhood’s environment may influence daily walking time. The perceptions of the neighborhood’s environmental factors that correlate with walking times differ between the different regional physical environments. Therefore, to promote physical activity, the consideration of environmental factors unique to residents’ neighborhood’s environments is needed.
