Associations of Type and Intensity of Physical Activity with Depressive Symptoms after Two Years in Community-dwelling Older Women

[Purpose] Physical activity (PA) decline has been reported as a risk factor for the onset of depressive symptoms. This study examined the association between type and intensity of PA and depressive symptoms after 2 years. [Participants and Methods] Participants were community-dwelling older women aged 65 and older (117 people) living in X City, Aichi Prefecture. A triaxial accelerometer was used to measure PA type and intensity, and the Geriatric Depression Scale-15 (GDS-15) was used to evaluate depressive symptoms. [Results] Structural equation modeling using multiple regression showed that only “2015 Non-locomotive light PA” had a significant effect on “2017 GDS-15.” [Conclusion] The result of this study suggests that Non-locomotive light PA may affect depressive symptoms after 2 years in community-dwelling older women.
