体育设施布局与老年人户外体力活动的关系——以南京市为例

The Relationship between the Layout of Sports Facilities and Outdoor Physical Activity among the Elderly--Taking Nanjing City as an Example

为了探讨体育设施布局与老年人户外体力活动之间的关系,多段分级抽取南京市32个社区内569名老年人,连续4天佩戴加速度计,利用GPS测量其户外体力活动的时空信息,同时使用地理信息系统测量老年人居住地周围500米缓冲区内的体育设施数量,运用STATA 12.0对数据进行分析。结果发现:缓冲区内有6~7个体育设施的老年人比无体育设施的老年人每天多花9.19分钟(95%CI:0.05~18.33)进行户外中大强度体力活动。性别、年龄和社区类型对老年人户外中大强度体力活动以及体力活动达标率产生显著影响。控制混杂因素后,缓冲区有6~7个体育设施的老年人户外中大强度体力活动以及体力活动达标率仍然比无体育设施的老年人高。建议加强城市社区体育设施建设,提高老年人身体素质。

In order to explore the relationship between the layout of sports facilities and outdoor physical activ⁃ities of the elderly,569 elderly people from 32 communities in Nanjing were selected by multi⁃stage classifica⁃tion.They wore accelerometers for 4 consecutive days and the spatio⁃temporal information of their outdoor physical activities was measured by GPS.Meanwhile,the number of sports facilities within a 500m buffer zone around the residence of the elderly was measured by geographic information system,and STATA 12.0 was used to analyze the data.The results show that older adults with 6 to 7 sports facilities in the buffer zone spent 9.19 minutes more per day(95%CI:0.05 to 18.33)on outdoor moderate intensity physical activity(MVPA)than those without sports facilities.Gender,age and community type have significant effects on outdoor MVPA and physical activity compliance rate of the elderly.After controlling for confounding factors,it is found that the outdoor MVPA attainment rate of the elderly with 6 to 7 sports facilities was higher than that of the elderly without facilities.It is suggested to strengthen the construction of sports facilities in urban communities to im⁃prove the health quality of the elderly.
