The association of subjective vision with objectively measured intensity-specific physical activity and bout-specific sedentary behavior among community-dwelling older adults in Japan.

Purpose: Visual impairment is a possible cause of physical frailty. Reduced physical activity (PA) may be involved in the pathway from visual impairment to physical frailty, although the association between vision and objectively measured PA among older adults remains unclear. This study examined the sex-specific association of subjective vision with intensity-specific PA and bout-specific sedentary behavior (SB) among community-dwelling, older Japanese adults.
