*Sleep scores were categorised into: poor, 0~1; intermediate, 2~3; healthy, 4~5. There were significant differences (p<0.05) across sleep score groups in all the characteristics shown in the table.
†Townsend area deprivation index was used.
‡Had ever seen a doctor or psychiatrist for nerves, anxiety or depression.
§Categorisation based on public health guidelines: no MVPA (those reported 0 MET-mins/week from MVPA, regardless of total MET-mins/week); low (<600 MET-mins/week); medium (600 to <1200 MET-mins/week); and high (≥1200 MET-mins/week).
¶The UK guideline (14 UK units/week) was used.
MET, metabolic equivalent task; MVPA, moderate-to-vigorous physical activity.
