测量在家和离家的身体状况对于评估健康和幸福感是必不可少的，并且可以帮助设计干预措施来增加身体活动。在这里，我们描述了如何在家里和离家出走的身体活动，可以通过结合信息从蜂窝网络为基础的跟踪设备和accelerometers.MethodsThirty工作的成年人穿着蜂窝网络为基础的跟踪设备和加速度计连续6天，并记录他们的旅行离家出走。跟踪设备的性能是使用旅行日志作为参考来确定的。跟踪设备和加速度计的数据进行了合并，以比较身体活动在家里和远离home.ResultsThe跟踪设备检测到98.6%的所有离家出走的游览，准确地测量离家出走的时间，并表现出一些长期的信号辍学期间。大多数体育活动都是在工作日离家进行的，而不是在周末。受试者每单位时间的身体活动，而离家出走，特别是在weekends.ConclusionsCellular网络为基础的跟踪设备代表了一种替代全球定位系统的跟踪位置，并提供信息，很容易与加速度计集成，以确定身体活动发生。促进更多的时间花在离家出走可能会增加身体活动。
BackgroundMeasuring physical at home and away from home is essential for assessing health and well-being, and could help design interventions to increase physical activity. Here, we describe how physical activity at home and away from home can be quantified by combining information from cellular network–based tracking devices and accelerometers.MethodsThirty-five working adults wore a cellular network–based tracking device and an accelerometer for 6 consecutive days and logged their travel away from home. Performance of the tracking device was determined using the travel log for reference. Tracking device and accelerometer data were merged to compare physical activity at home and away from home.ResultsThe tracking device detected 98.6% of all away-from-home excursions, accurately measured time away from home and demonstrated few prolonged signal drop-out periods. Most physical activity took place away from home on weekdays, but not on weekends. Subjects were more physically active per unit of time while away from home, particularly on weekends.ConclusionsCellular network–based tracking devices represent an alternative to global positioning systems for tracking location, and provide information easily integrated with accelerometers to determine where physical activity takes place. Promoting greater time spent away from home may increase physical activity.
