  • *HR for mortality per 30 min of LIPA per day (continuous variable).

  • †Model 1=age+region of residence+season of wear+accelerometer wear time.

  • ‡Model 2=model 1+social class+alcohol use+smoking+ sleep time+living alone+body mass index.

  • §Model 3=model 2+mobility disability.

  • ¶Model 4=model 3+MVPA.

  • **Model 5=model 3+sedentary behaviour+MVPA (but without adjustment for accelerometer wear time).

  • CHD, coronary heart disease; LIPA, light physical activity; MVPA, moderate to vigorous physical activity.
