全球定位系统（GPS）代表了一种客观评估身体活动行为空间位置的创新方法。本系统综述的目的是确定GPS在身体活动与环境关系研究中收集活动位置高质量数据的能力。2010年夏季，系统检索了截至2010年3月的7个电子数据库、参考书目、参考书目和网站中已发表和未发表的文章，并对其进行了评估和分析。包括使用GPS测量身体活动的空间位置以及与GPS数据相关的某种形式的环境分析的研究。GPS的能力用数据质量来表示，而数据质量又被定义为每项研究中丢失的GPS数据的比例。24项研究符合纳入标准。数据丢失与参与者被要求佩戴GPS设备的测量期间呈正相关（r=0.81, p<0.001）。数据丢失的主要原因包括信号丢失、设备电池电量损失以及参与者对测量协议的依从性差。数据丢失在儿童和成人之间、研究样本量、出版年份或GPS设备制造商之间没有显著差异。GPS是一个很有前途的工具，可以提高我们对身体活动的空间背景的理解。我们的研究结果表明，选择合适的设备和努力最大限度地提高参与者的依从性是提高数据质量的关键，特别是在较长的研究期间。
The Global Positioning System (GPS) represents an innovative way to objectively assess the spatial locations of physical activity behavior. The aim of this systematic review was to determine the capability of GPS to collect high quality data on the location of activities in research on the relationship between physical activity and the environment. Published and unpublished articles identified from seven electronic databases, reference lists, bibliographies and websites up to March 2010 were systematically searched for, appraised and analysed in summer 2010. Included studies used GPS to measure the spatial locations of physical activity and some form of environmental analysis related to the GPS data. The capability of GPS was expressed in terms of data quality which in turn was defined as the proportion of GPS data lost in each study. 24 studies met the inclusion criteria. Data loss was positively correlated with the measurement period for which participants were asked to wear the GPS device (r=0.81, p<0.001). Major reasons for data loss included signal drop outs, loss of device battery power, and poor adherence of participants to measurement protocols. Data loss did not differ significantly between children and adults or by study sample size, year of publication or GPS device manufacturer. GPS is a promising tool for improving our understanding of the spatial context of physical activity. Our findings suggest that the choice of an appropriate device and efforts to maximise participant adherence are key improving data quality, especially over longer study periods.
