Daily adolescent sleep, Mexico 2019 [dataset]

Data on sleep behaviour, daily physical activity and ambient light was collected via Motionlogger Micro Watch units (Ambulatory Monitoring Inc., US). The actigraphs were set for 1-min epochs in the Zero Crossing Mode (ZCM). Participants between 11 and 16 years old wore the actigraphy devices during 10 days (six work days and four free days) for 24 hours. Adolescents were asked to press the event logger button before any sleep event across the study. The actigraphy records were analyzed with the ActionW 2.7 software employing the Sadeh algorithm to characterize the sleep-wake behaviour of adolescents. We used sleep diaries to further validate the accuracy of sleep scores generated by the software. When encountering a nap episode, missing data (caused by a watch malfunction or off-wrist period) or additional information regarding the participant's sleep-wake behaviour derived from sleep diary, the analyst edited the scores manually.
