Dissertation: 17.2.2017 Walking, physical activity, and life-space mobility among older people (Tsai) <\/h1><\/div>
TtM Li-Tang Tsain defends her doctoral dissertation in Gerontology and Public Health \u201dWalking, physical activity and life-space mobility among older people\u201d. Opponent, Adjunct Professor, Academy Researcher Sari Stenholm (University of Turku) and custos Professor Taina Rantanen (University of Jyv\u00e4skyl\u00e4). <\/div>

Autonomy in mobility is a central component of active ageing. Life-space mobility describes where, when, and how an individual reaches desired destinations. Walking, an important form of physical activity among older people, is a prerequisite for engaging in daily activities. This study explored the cross-sectional and longitudinal relationships between physical activity and life-space mobility. The associations of walking with reasons for going outdoors in different life-space areas, living arrangements, and environmental barriers to mobility were also examined.<\/p>

Data from two larger studies were used: the Life-Space Mobility in Old Age (LISPE) accelerometer substudy (n=174, median age 79.7) and Screening and Counseling for Physical Activity and Mobility in Older People (SCAMOB) (n=657, median age 77.0). Participants were community-dwelling older people living in Central Finland. Physical activity and step count were measured by an accelerometer (Hookie, tri-axial, \u201cAM20 Activity Meter\u201d) for 7 days. Life-space mobility was assessed with the University of Alabama at Birmingham Study of Aging Life-Space Assessment. Reasons for going outdoors, walking for errands and environmental mobility barriers were self-reported.<\/p>

The cross-sectional analyses showed that life-space mobility correlated with objectively measured physical activity. Over the two-year follow-up, a lower step count and less moderate-intensity physical activity at baseline preceded a significantly steeper decline in life-space mobility. In old age, a higher amount of walking activity was associated with going outdoors for shopping or walking for exercise, living alone, and perceiving fewer environmental mobility barriers.\u00a0<\/p>

This study indicates more time spent walking outdoors and the accumulation of moderate-intensity physical activity may help to maintain higher life-space mobility, a correlate of good quality of life. In promoting walking activity among community-dwelling older people, both individual and environmental factors should be taken into account.<\/p>
