Longitudinal study reveals greenness outside residences affects physical activity patterns in retirees, suggesting further exploration is needed.
Key Points
This study aims to investigate the association between greenness exposure in activity spaces and physical activity behavior before and after retirement.
Conducted longitudinal study using data from the Finnish Retirement and Aging study (FIREA).
Included participants with valid accelerometer and GPS data before and after retirement.
Measured various physical activity levels, including light, moderate-to-vigorous, total, and transportation activity.
Utilized GPS data and normalized difference vegetation index (NDVI) to assess greenness exposure.
Analyzed cross-sectional and longitudinal changes in physical activity and greenness exposure.
Higher greenness exposure was linked to less moderate-to-vigorous physical activity (MVPA) and transportation activity on workdays.
MVPA and transportation activity increased among participants from workdays to retirement days.
No significant associations were found between changes in greenness exposure and changes in physical activity levels.
