| Annotation | The study aimed to quantify and describe habitual active and sedentary behaviour in older, community-dwelling adults and to explore the characteristics that contribute to this behaviour. 56 community-dwelling older adults with an average age of 79 years wore an ActivPAL accelerometer for seven days and were assessed for a range of motor, cognitive and affective characteristics. Seven variables derived from accelerometry considered to represent four characteristics of habitual behaviour (volume, frequency, intensity and variability) were submitted to principal components factor analysis (PCA). Factor scores were retained and used as dependent variables in regression analysis. Three significant orthogonal factors emerged from the PCA, accounting for 80% of the variance in test scores: `walking behaviour' which accounted for 39% of variance in the model; `sedentary behaviour' explaining 24.3% of total variance; and `postural transitions' which accounted for 16.7% of total variance. Concludes that walking, sedentary and transitory behaviours are distinct from each other, and together explain daily function. Further research on a larger sample is indicated to explore the characteristics that explain these behaviours, in particular the interplay between sedentary behaviour and periods of physical activity.
