BMI, body-mass index; IQR, interquartile range; NWT, non-wear time. ^aThe total number of waking and sleeping phases were summed up per participant and divided by two to consider one waking and one sleeping phase as average 24 h.

^bAnalyses were conducted from the first to the last recorded time point of assessment in the diary.

^cWaking and sleeping phases were derived from participants’ diary entries.
