Summary
Older Canadians spend most of their day sedentary, regardless of employment status. Reducing sedentary time (ST) is crucial for improving health outcomes in this population.
Area of Science:
- Gerontology
- Public Health
- Epidemiology
Background:
- Sedentary time (ST) is a growing public health concern, particularly among older adults.
- Understanding factors influencing ST in this demographic is essential for targeted interventions.
Purpose of the Study:
- To objectively measure and self-report leisure sedentary time in older Canadians.
- To examine the relationship between work status and sedentary time.
Main Methods:
- Analysis of 1729 older adults (60-79 years) from the Canadian Health Measures Survey.
- Objective measurement of total sedentary time (ST) using accelerometers.
- Self-report questionnaires for leisure sedentary activities, work status, and health indicators.
Main Results:
- 93.6% of participants were sedentary for ≥8 hours daily.
- Objectively measured ST did not differ by work status.
- Self-reported leisure ST was higher in non-working older adults.
Conclusions:
- Older adults accumulate significant sedentary time irrespective of work status.
- Sedentary time is associated with health risk indicators like poor perceived health and high waist circumference.
- Older adults represent a key target group for interventions aimed at reducing sedentary behavior.
