Abstract
151Factors Associated With Change In Objectively Measured Physical Activity In Older People - Data From The Physical Activity Cohort Scotland Study
Highlights
Cross-sectional relationships between physical activity and health have been explored extensively, but less is known about how physical activity changes with time in older people
Sex, deprivation decile, most SF-36 domains, most measures of social connectedness, most measures from the extended Theory of Planned Behaviour, hypertension, diabetes mellitus, chronic pain and depression score were significantly associated with adjusted activity counts at follow-up
We report the results of follow-up measurements of physical activity taken 2–3 years after the baseline visit in the Physical Activity Cohort Scotland (PACS) cohort, and examine the factors predicting change in objectively measured physical activity in this cohort of older, community dwelling people
Summary
Cross-sectional relationships between physical activity and health have been explored extensively, but less is known about how physical activity changes with time in older people. Physical activity promotion has often focussed on vigorous activity [3], and interventions have often targeted individual-level factors at the expense of social and environmental factors [4] Such approaches are unlikely to be sufficient, and successful strategies to encourage physical activity in later life are likely to require complex interventions aimed at modifying several factors. Many previous studies have not measured activity objectively, instead relying on subjective reports of activity, often using questionnaires. Such approaches are known to lack accuracy in older people as well as younger people [11, 12], and there is a clear need for studies using objective methods of capturing how much PA older people undertake in their daily lives
