doi: 10.1136/bmj.l4570

Figure Lengend Snippet: Characteristics of studies included in the meta-analysis

Article Snippet: Data from two studies that assessed physical activity by the Actical accelerometer were only included for time spent in moderate-to-vigorous intensity physical activity for the dose-response analyses because of the noticeable difference in absolute output for the other exposure variables compared with the Actigraph accelerometer.

Techniques: Filtration, Activity Assay

Article Snippet: The aims of this study are to: 1) validate the count-scaled algorithm against overnight PSG in children aged 5 to 8 years using two devices; the omnidirectional Actical and the triaxial ActiGraph GTX3+, 2) to compare different site placements (wrist vs hip) to determine the best placement site for measuring sleep, and 3) to compare the count-scaled automated algorithm to the most common algorithm used in child actigraphy, the Sadeh algorithm.
