This study employed novel GPS methods to assess the effect of a multilevel physical activity (PA) intervention on device-measured walking locations in 305 community dwelling older adults, ages 65+ (mean age = 83, 73% women). Retirement communities were randomized to a 1-year PA intervention that encouraged neighborhood walking, or to a healthy aging control condition. Total time and time spent walking in four life-space domains were assessed using GPS and accelerometer devices. The intervention increased the time spent walking as a proportion of total time spent in the Campus, Neighborhood and Beyond Neighborhood domains. Intervention effects on walking location were observed in both genders and across physical and cognitive functioning groups. Results demonstrate that an intervention providing individual, social and environmental support for walking can increase PA in larger life-space domains for a broad spectrum of older adults.
本研究采用新的 GPS 方法评估了一项多层次体力活动（PA）干预对 305 名 65 岁以上（平均年龄 83 岁，73%为女性）社区居住的老年人设备测量的步行地点的影响。退休社区被随机分配到为期一年的 PA 干预组，鼓励在社区附近散步，或接受健康老龄化对照组。使用 GPS 和加速度计设备评估了四个生活空间领域的总时间和步行时间。该干预措施增加了在校园、社区和社区以外的四个生活空间领域的步行时间占总时间的比例。在男女两性以及身体和认知功能组中均观察到了对步行地点的干预效果。结果表明，为步行提供个人、社会和环境支持的干预措施可以增加更大生活空间领域的 PA，适用于广泛的老年人。
