    Device-based physical activity measures for population surveillance—issues of selection bias and reactivity by Lars Breum Christiansen, Sofie Koch, Adrian Bauman, Adrian Bauman, Mette Toftager, Christina Bjørk Petersen, Jasper Schipperijn

    Published 2023-08-01
    “…BackgroundDevice-based measurement in physical activity surveillance is increasing, but research design choices could increase the risk of self-selection bias and reactive behaviour. The aim of this study is to compare the self-reported physical activity profiles of four different samples: participants in a large national survey, participants in a telephone-based survey of non-responders, participants in the large national survey who accepted the invitation to device-based measuring, and the same sample during the week of monitoring.MethodsIn October 2020, 163,133 Danish adults participated in a national survey and of those 39,480 signed up for device-based measurements. …”
