| Research Abstract |
The purpose of the study was to investigate whether neighborhood environments would correlate with residents' physical activity in Japan, and this study was the first trial of this kind in Japan.
In the first year of this study, we analyzed previous studies and referred to related literature and papers. According to the results of previous studies, we concluded that the study region should be several different areas, environmental factors should be assessed by objectively and subjectively perceived measures, and multiple dimensions of physical activity such as transportation, leisure, etc. should be included.
The Geographic Information System (GIS) was used to objectively assess the physical residential environment. We proposed the measurement methods and assessment items using GIS. Using the database of the these measurement methods and items, study subjects could be classified according to the individual neighborhood environments, such as residential density, connectivity of street and

land use mix, etc.
Also, an assessment method for the perceived environments of the residents was tested for reliability In this study, the Japanese version of the Abbreviated Neighborhood Environment Walkability Scale (ANEWS) was prepared. Thus, an international comparison study is feasible and will be conducted in the near future.
The daily physical activity of the residents was objectively assessed by pedometer and accelerometer And a subjective method using the International Physical Activity Questionnaire (IPAQ) was also tested.
To include different cultural and/or social regions in this study we selected different study areas a Tokyo metropolitan district and two local cities The study survey was conducted to delineate the association between neighborhood environments and residents' physical activity. The study results suggested that the neighborhood environment might influence residents' daily physical activity. However, the association between neighborhood environments and residents' physical activity was different depending on sex and region. Therefore, to promote physical activity, we concluded that the consideration of environmental factors unique to residents' neighborhood environments is needed.
We proposed a new method using the three elements of location, time and physical activity, simultaneously. To assess these elements, GIS, accelerometer and small -sized Global Positioning System (GPS) were used. And we could integrate these three sources of data as a tool for assessing residents' individual behavior patterns. Now, we can clarify the characteristics of the association between neighborhood environments and physical activity.
In the near future, we will present useful evidence for urban planning linked to residents' health behaviors. Less
