  1. Significant values are in bold.
  2. Hrs decimal hours, b (SE) regression estimate and standard error, TST Total Sleep Time, WASO Wake after sleep onset, SOL Sleep onset latency. Type of night is a two category variable distinguishing Work nights (nights preceding a day of work or a day of school, dummy coded as 1) and free nights (night preceding a free day, reference, dummy coded as 0). Gender was a two category variable with girl group as reference (dummy coded as 0) and boy (dummy coded as 1).
