GISを活用した自宅近隣環境の再認知による身体活動量を増やす試み

抄録

Objectives: In this study, we used a geographic information system (GIS) to create a map that showed the neighborhood environment. We then performed an interventional study to assess the ability of the program to increase physical activity. Methods: Participants included 51 residents of Hadano city in Kanagawa prefecture (Age: 64.8∓9.5 years). The intervention period was 2 months. We created walking maps of two types (10 minutes course and burn off 100kcal course) to promote familiarity with the neighborhood environment and to increase physical activity. We distributed this map in an exercise class. The primary outcome was increased walking for physical activity, assessed with the International Physical Activity Questionnaire Short Version (IPAQ-SV). Statistical analysis using the Wilcoxon signed rank test compared walking activity before and after the intervention. Results: Five participants began to exercise during the intervention period. The mean level of the physical activity of walking before the intervention was 343∓313 min/week, and the level after intervention was 454∓372 min/week(p=0.009). This was equal to an increase in stepping time of 16 minutes. Conclusion: The program developed for this study increased the physical activity of walking among the participants, and may be effective as a tool to increase overall physical activity.
