TL;DR: The two actigraphs provided comparable and accurate data compared to in-home polysomnography (PSG), although both poorly identified wake episodes (i.e., had low specificity).

TL;DR: Evidence-guided information is summarized for 7 areas that are of importance in the design and interpretation of studies using actigraphy that are intended to enhance the appropriate use of accelerometry for assessing physical activity, sedentary behavior, and sleep behaviors in research studies.

TL;DR: Season was associated with large changes in sleep timing, and smaller changes in other sleep and PA measurements, and future health behavioral interventions may benefit by targeting “season-specific” interventions.

TL;DR: Sleep fragmentation, defined by low sleep efficiency, was associated with higher odds of migraine on day 1, and short sleep duration and low sleep quality were not temporally associated with migraine.

TL;DR: Timing of zeitgebers was associated with sleep and rest-activity patterns, including bedtimes, L5 and M10 midpoint, and there was a significant interaction between morning chronotype and first eating episode with rest- activity patterns, with firsteating episode associating with timing of activities only in non-morning type adults.
