Participants provided informed consent, completed a demographic questionnaire and stature and mass were also assessed. Participants were then asked to wear an activPAL on their left thigh for 24 hours/day for seven consecutive days. Participants were given a wear diary, where they were asked to record what time they woke up and when they went to sleep and to record if the activPAL was removed and the reasons for removal. After one week, participants returned the activPAL and the wear diary to the researchers, and completed the Hospital Anxiety and Depression Scale (HADS) and the Short Form-12 questionnaire (SF-12). Sedentary time was calculated as monitor recorded sitting or lying time minus wear diary recorded sleep time. Wear diary sleep time was verified against monitor recorded activity.
