【摘要】:目的:分析以地理信息系統(tǒng)(GIS)測量的住所周圍建成環(huán)境與香港兒童體力活動的關(guān)系。方法:本研究的樣本為香港一間小學的81名7~11歲兒童(男生44人)。本研究數(shù)據(jù)來自一項為期三年的追蹤研究——兒童體力活動與營養(yǎng)調(diào)查(UCAN計劃)。受試兒童體力活動分別以Acti Graph GT3X型加速度計和家長問卷進行測量。受試兒童住所周圍道路總長度及住所至最近康樂設施的距離以GIS(Arc Map 10.0)測量。受試兒童被分為長道路組(住所周圍道路總長度≥50百分位)與短道路組(住所周圍道路總長度50百分位),及近設施組(住所至最近康樂設施的距離≤50百分位)與遠設施組(住所至最近康樂設施的距離50百分位)。各組間(長道路組vs.短道路組;近設施組vs.遠設施組)的體力活動時間差異以單因素協(xié)方差分析比較,同時控制受試兒童性別、年齡、身體質(zhì)量指數(shù)(BMI)及母親受教育水平。結(jié)果:加速度計測量的數(shù)據(jù)顯示,男生無論在上學日還是周末日均比女生活躍。在控制受試兒童性別、年齡、BMI及母親受教育水平后,單因素協(xié)方差分析顯示相對于遠設施組兒童,近設施組兒童參與中高強度體力活動時間較長(126.8±34.4 vs.113.6±27.1分鐘/天,P0.05);而兩組間問卷報告的體力活動無差異。長道路組與短道路組間加速度計及問卷測量的體力活動均未見差異。結(jié)論:本研究初步證實,住所附近康樂設施對香港兒童的體力活動具有積極影響。今后的研究應納入更具代表性的樣本及更多的建成環(huán)境指標,以獲得城市建成環(huán)境與兒童體力活動關(guān)系的更有力證據(jù)。
[Abstract]:Objective: to analyze the relationship between the built environment and physical activity of children in Hong Kong. Methods: a sample of 81 7- and 11-year-old children (44 males) from a primary school in Hong Kong was studied. This study was based on a three-year tracking study, the Children's physical activity and Nutrition Survey (UCAN Program). The physical activity of children was measured by Acti Graph GT3X accelerometer and parent questionnaire. The total length of the road around the residence and the distance from the residence to the nearest Kang Le facility were measured in GIS (Arc Map 10.0). The children were divided into long road group (total length of road around residence 鈮,
