背景:身体活动监测系统对于公共卫生监测很重要,但主要依赖于身体活动的自我报告测量。在此类系统中集成基于设备的测量可以改善人口估计,然而,这在现有的监测系统中仍然相对罕见。本系统审查旨在概述现有基于设备的国家PA监视系统中使用的方法。
方法:四个文献数据库(PubMed,Embase.com,搜索了SPORTDiscus和WebofScience),辅以反向跟踪。如果文章报告了基于人口的(国家间)监测系统测量PA,久坐时间和/或遵守PA指南。如果可用和英语,已确定的监测研究的方法学报告也纳入了数据提取.
结果:这项系统的文献检索遵循了PRISMA指南,产生了34篇文章和另外18份方法学报告。报告28项研究,它又报告了15个不同的国家和1个国际监测系统的一个或多个波。纳入的研究表明,参与者数量的系统(波)之间存在很大差异,反应率,人口代表性和招募。相比之下,这些方法在数据缩减定义上是相似的(例如,最小有效天数,有效日的非磨损时间和必要的磨损时间)。
结论:本综述的结果表明,很少有国家在其监测系统中使用基于设备的PA测量。采用的方法是多种多样的,这阻碍了国家之间的可比性,并要求更标准化的方法以及对这些方法的标准化报告。这项审查的结果可以帮助将基于设备的PA测量集成到(国家间)国家监测系统中。
BACKGROUND: Physical activity surveillance systems are important for public health monitoring but rely mostly on self-report measurement of physical activity. Integration of device-based measurements in such systems can improve population estimates, however this is still relatively uncommon in existing surveillance systems. This systematic review aims to create an overview of the methodology used in existing device-based national PA surveillance systems.
METHODS: Four literature databases (PubMed, Embase.com, SPORTDiscus and Web of Science) were searched, supplemented with backward tracking. Articles were included if they reported on population-based (inter)national surveillance systems measuring PA, sedentary time and/or adherence to PA guidelines. When available and in English, the methodological reports of the identified surveillance studies were also included for data extraction.
RESULTS: This systematic literature search followed the PRISMA guidelines and yielded 34 articles and an additional 18 methodological reports, reporting on 28 studies, which in turn reported on one or multiple waves of 15 different national and 1 international surveillance system. The included studies showed substantial variation between (waves of) systems in number of participants, response rates, population representativeness and recruitment. In contrast, the methods were similar on data reduction definitions (e.g. minimal number of valid days, non-wear time and necessary wear time for a valid day).
CONCLUSIONS: The results of this review indicate that few countries use device-based PA measurement in their surveillance system. The employed methodology is diverse, which hampers comparability between countries and calls for more standardized methods as well as standardized reporting on these methods. The results from this review can help inform the integration of device-based PA measurement in (inter)national surveillance systems.
