The reasons to be sedentary could be grouped into three categories and there were 18 responses that did not fit into a category. (See Appendix 1 on the

eAddenda for details of these isolated responses.) The most frequently reported reason to be sedentary was poor weather (48%), followed by health problems (43%) and lack of intrinsic motivation (11%). In addition 20% of the participants reported having no reason to be sedentary. On average, participants reported 1.7 (range 1 to 4) reasons to be physically active and 1.2 (range 0 to 3) reasons to be sedentary. Self-efficacy for physical activity was explored during a conversation with the participant about whether he/she felt confident in the ability to perform the physical activities he/she executes. If a participant reported confidence this was categorised as ‘high self-efficacy’. Positive social support for physical activity was reported by almost 50% of the study population.
