【摘要】：目的:通过佩戴GPS定位器和体力活动加速度计对儿童青少年进行四周体力活动追踪,分析儿童青少年日常体力活动空间半径,为适宜步行缓冲区尺寸大小提供建议,验证当前普遍采用的儿童青少年一周体力活动数据的采集是否能够全面地反映其日常活动空间特征。方法:选取上海市杨浦片区小学四年级到高二共121名受试者(9-17岁)参与测试,佩戴GPS定位器和体力活动加速度计四周,检测样本人群体力活动发生场所位置的经纬度以及体力活动强度的大小,并将中高强度体力活动数据和GPS定位器数据匹配,确定中高强度体力活动场所的位置。从而分析中高强度体力活动发生场所的空间特征,并且通过经纬度坐标算出中到大强度体力活动发生场所距离家和学校的距离。结果:根据GPS与加速度计数据筛选原则,有效样本共52名(男生,27名;女生,25名)。上学日受试者中高强度体力活动多集中在学校、通勤路径,而周末则集中在运动场所/锻炼设施、沿街道的出行活动轨迹和小区。距离小区和学校600米范围内集中了受试者人群多数的体力活动定位点,一周的追踪测试结果和四周追踪测试结果无显著差异。结论:建议今后有关儿童青少年体力活动干预多围绕小区及周边进行,针对儿童青少年公共服务设施的配置标准以及环境评估建议以600米作为缓冲距离,类似的研究建议可采用一周的测试。
[Abstract]:Objective: to analyze the spatial radius of daily physical activity of children and adolescents by using GPS locator and physical activity accelerometer to track the physical activity of children and adolescents, and to provide suggestions for the size of walking buffer zone.To verify that the current data collection of physical activity of children and adolescents can reflect the spatial characteristics of daily activities.Methods: a total of 121 subjects aged 9-17 years from grade four to grade two in Yangpu district of Shanghai were selected to take part in the test, and the subjects wore GPS positioner and physical activity accelerometer for four weeks.The longitude and latitude of the physical activity occurrence place and the physical activity intensity of the sample population were detected, and the middle and high intensity physical activity data and the GPS locator data were matched to determine the location of the middle and high intensity physical activity place.The spatial characteristics of the middle and high intensity physical activity are analyzed, and the distance from home to school is calculated by latitude and longitude coordinates.Results: according to the principle of GPS and accelerometer data screening, there were 52 effective samples (27 males and 25 females).The high-intensity physical activity of the subjects on school day was mainly concentrated in the school and commuter paths, while the weekend was concentrated in the exercise place / exercise facilities, along the street travel track and community.Within 600 meters of distance from the community and school, the physical activity location of most of the subjects was concentrated, and there was no significant difference between the results of a week's tracking test and that of the four-week tracking test.Conclusion: it is suggested that the intervention of physical activities of children and adolescents should be carried out mainly around the residential area and surrounding areas in the future, and that 600 meters should be used as the buffer distance for the allocation of public service facilities for children and adolescents and the environmental assessment.Similar studies suggest a one-week test.
