Brief Summary

The purpose of this study is to map the context of sedentary behaviour among older adults who are frail. This study uses a unique combination of objective and self-report measures to assess context. The investigators will also hold focus groups to understand which behaviours can be modified and conduct an analysis to understand which types of behaviours are associated with negative health outcomes.

Detailed Description

Older adults who are frail are potentially the population that might benefit the most from a reduction in sedentary time as they are the most sedentary group and have the highest chronic disease burden. However, there is a dearth of evidence on effective interventions to reduce sedentary behaviour or total sedentary time in older adults, especially among individuals that are frail. Previous studies focused on reducing total sedentary time, while other studies aimed to increase physical activity levels with the assumption that sedentary time will be reallocated to physical activity. But, to date, such interventions have not been effective at reducing total sedentary behaviour time in older adults. Previous studies to reduce sedentary time and behaviour in older adults may not be effective because there is no research on the context of sedentary behaviour, about when and where to intervene, and which specific sedentary behaviours should be targeted. Almost all studies in older adults have assessed total sedentary time, which does not provide enough information to understand the context of sedentary behaviours. The main reason to understand context is because not all sedentary behaviours should be modified as some cognitively engaging sedentary behaviours (e.g., reading, socializing) appear to benefit health, while time spent in more passive activities may be detrimental. Therefore, the goal should not be to reduce total sedentary time, but rather identify sedentary behaviours that may be detrimental to the health of older adults who are frail.

Before we can develop an intervention to reduce sedentary behaviour among older adults, we must first assess the context of sedentary behaviour. Context is defined as the purpose of the sedentary behaviours, the location where the behaviours occur, the posture of the behaviours (e.g., lying, sitting), social context (e.g., alone or with others), and time of day the behaviours occur. The purpose of this study was to assess the feasibility of measuring the context of sedentary behaviour among older adults who are frail. We defined feasibility using recruitment, retention, and refusal rates (process) and the feasibility resource (i.e., can the tools capture context and are participants willing to use the tools). Our criteria for success were to recruit 20 participants within two months, 85% retention, and 20% refusal. Our secondary objectives are: 1) to determine the context of using objective and subjective measures to assess sedentary behaviours among older adults who are frail; 2) to identify which types of sedentary behaviours can be modified and when and where to intervene; and 3) to conduct an exploratory analysis to determine the association of certain types of sedentary behaviours on health-related outcomes.

Study Groups

Total number of participants

As this is not an intervention study, the investigators only have one group which the investigators will follow at two-time points to map the context of sedentary behaviour.

No interventions assigned to this group
