Abbreviations: MVPA, moderate-to-vigorous physical activity; REM, rapid eye movement sleep; TST, total sleep time; TIB, time in bed.
Values are presented as mean±standard deviation.
Time-based variables (MVPA, sedentary, awake, sleep stages, TST, and TIB) are expressed in minutes per day, and sleep efficiency is expressed as a percentage (%).
