A new study entitled “The Use of Wearable Cameras to Capture Physical Activity and Sedentary Behavior: A Scoping Review” was recently published in Journal for the Measurement of Physical Behaviour. A summary and citation are included below.
ABSTRACT
Physical activity (PA) and sedentary behavior (SB) are deeply ingrained within everyday life. It is important to capture all dimensions of PA and SB given their impact on health where the ideal measurement tool is able to measure the frequency, intensity, duration, and type of PA and SB when they occur. Media from wearable cameras (WCs) have seen increased use within the scientific literature for capturing health behavior, but their use for capturing PA and SB has not been systematically reviewed before. Therefore, the purpose of this scoping review was to determine the extent of WC media use for detailing PA and SB. A variety of record types from seven databases was searched from database inception to November 2023. Seventy-four sources were included, with purposes of WC media for capturing PA and SB for first-person activity recognition, to provide primary or secondary study outcome measures to be used as the ground truth measure for other measurement tools and for validation of WC media estimates of PA and SB. Both still images and video from WCs were used to capture the frequency, intensity, and duration of PA and SB, with 100% of included sources using WC media to capture types of PA and SB. Despite the extensive use of WC media to capture PA and SB, few studies have rigorously established the concurrent validity of WC media estimations of PA and SB against gold-standard measures, and participant characteristics within the first-person activity recognition field are seldom reported.
