*HR for mortality per 10 min of MVPA 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+sedentary behaviour.
**Model 5=model 3+sedentary behaviour+LIPA (but without adjustment for accelerometer wear time).
CHD, coronary heart disease; LIPA, light physical activity; MVPA, moderate to vigorous physical activity.
