A. Average change in weekday (Mon–Fri) waking activity time depending on sleep time category (N=23,325) based on multiple linear regression models adjusting for age, gender, ethnicity, educational attainment, income, presence of partner, and presence of children. The 7.5 h to <8.5 h sleep time category served as reference. Upper boundaries of 1 h sleep time ranges are shown on the abscissa, except for the lowest and highest category, which extend to minimum and maximum sleep time. For work time, separate models were run for the whole group (Work) and restricting data to those who worked on the interview day (Work > 0 min).B. Average change in weekend (Sat+Sun) waking activity time depending on sleep time category (N=23,563).
