Global positioning system (GPS) technology has been increasingly used in aging research as a tool for reliably capturing the level and patterns of mobility among older adults. This article aims to systematically review the current state of GPS-based mobility research with community-dwelling older adults. Twenty-nine studies from 2008 to 2019 are included. Included studies examined various forms of temporal and spatial mobility measures. This review provides a synthesis of the current evidence on the risk factors or correlates of GPS-driven mobility limitations, such as demographic, cognitive, physical, psychological, and environmental factors. There is variability in types of GPS technology and GPS-derived mobility measures, GPS recording methods, data processing, and correlates of mobility limitation across studies. Future research should focus on identifying meaningful GPS-derived mobility measures and developing standardized protocols for GPS administration and data analytics for comparison across studies.
全球定位系统（GPS）技术已越来越多地被用于老龄化研究，作为一种可靠地捕捉老年人移动水平和模式的工具。本文旨在系统地回顾基于 GPS 的社区居住老年人移动性研究的现状。纳入了 2008 年至 2019 年的 29 项研究。纳入的研究检查了各种形式的时间和空间移动性测量。本综述提供了当前关于 GPS 驱动的移动障碍的风险因素或相关性的综合证据，例如人口统计学、认知、身体、心理和环境因素。研究之间在 GPS 技术和 GPS 衍生的移动性测量、GPS 记录方法、数据处理以及移动障碍的相关性方面存在差异。未来的研究应集中于确定有意义的 GPS 衍生的移动性测量，并为 GPS 管理和数据分析制定标准化协议，以便在研究之间进行比较。
