This study will allow for an investigation using accelerometry and GPS data of older adults PA and SB in distinct behavioral settings in order to identify potential for interventions. Expected settings include home, work, transportation and public open spaces. Results will respond to what the state of PA and SB are in older populations, as well as where such behavior occurs. Moreover, we expect to understand what are older adults’ use of space to better tailor programs to promote PA, social interaction, and integral use of spaces.
