*Percentage sedentary=100×sedentary (<100 cpm) minutes/total wear time (min).
†A bout of sedentary behaviour is a period of consecutive minutes where the accelerometer registers <100 cpm.
‡A break in sedentary behaviour is at least one minute where the accelerometer registers >100 cpm following a sedentary bout.
§Marginal means are adjusted for age, BMI, smoking status, wear time, day order of week, number of chronic diseases and depression.
¶p Value tests for equal means across all levels of the subgroup.
**Ambulatory men, not in a care home, no missing covariate data.
††Pairwise mean difference p<0.05 when compared to age <75, BMI <25, non-smoker, not depressed, or 0 chronic conditions.
BMI, body mass index.
