本研究目的以生態模式探討環境與休閒時間身體活動之間的關係,並分析在不同環境下,休閒時間身體活動量是否有所不同。環境變項來自國家衛生研究院「國民健康訪問調查」之都市化程度、教育部體育署「全國運動場館資訊網」之運動設施資料庫及內政部國土測繪中心「綠地面積」。研究資料為2013年「國民健康訪問調查」16,125名25歲以上的成人,前一週休閒時間身體活動的頻率、時間、強度,並依據世界衛生組織建議量分為以下兩類,其分別為達到休閒時間身體活動量與未達到休閒時間身體活動量。分析結果指出:住在都市地區民眾有較高的機率達到身體活動建議標準量;運動設施密度較高地區比密度低地區,達到身體活動建議標準量機率較低;綠地面積與休閒時間身體活動量無關。本研究結論認為休閒時間身體活動存在城鄉差距,而運動設施密度與綠地面積無法直接提升休閒時間身體活動量。政策及實務上,應考量不同人口特性的影響,尤其低社經地位者或鄉村地區,政府或社區政策介入更顯重要。
The purpose of this study was to investigate the relationship between the environment and leisure-time physical activity from the ecological model by presenting levels of leisure-time physical activity under different circumstances. The environmental variables and data sources included the degree of urbanization (from the 2013 the National Institutes of Health Survey), density of sport facilities (from the Sports Department of the Ministry of Education), and green space (from the National Land Surveying and Mapping Center, Ministry of the Interior, Taiwan). Data from the 2013 National Health Interview Survey, which included 16,125 adults over the age of 25, calculated leisure-time physical activity by compiling frequency, time and calorie expenditure of leisure-time physical activity in the previous week into a composite indicator, and divided subjects into sufficient physical activity and physical inactivity. Results indicated that people living in urban areas had higher probability of getting the recommended amount of leisure-time physical activity than those in rural areas. Those in areas with a higher sport facilities density had a lower probability of meeting the recommended levels of leisure-time physical activity than those in areas with lower density. Size of green space was not associated with levels of leisure-time physical activity. We conclude that there is an urban-rural divide in leisure-time physical activity. Density of sport facilities and size of green space are not sufficient to support physical activity. Our findings generate policy implications designed to take demographic characteristics into consideration, especially of those in less privileged positions, when designing community-level intervention.
