Changes in objectively measured outdoor time and physical, psychological, and cognitive function among older adults with cognitive impairments

摘要

Background: Older adults with cognitive impairment are at higher risk for various health problems. Although previous studies have suggested going outdoors more frequently might be effective to promote health, no longitudinal studies have examined objectively measured outdoor time in this population. This study examined the relationships between changes in objectively measured outdoor time and physical, psychological, and cognitive functions among older adults with cognitive impairments.
