Association of daily step patterns with frailty in community older Chinese women

Abstract

To investigate the association between the number of days an individual takes 8,000 steps or more and frailty among older chinese women. The number of days per week taking 8,000 steps or more were measured with triaxial accelerometers. The Fried Phenotype model was used to assess frailty status. Compared to participants who walked 8,000 steps or more 0 days per week, the odds ratio of frailty was lower among those who took 8,000 steps or more 1-2 days and 3-7 days per week. Additionally, taking 3,800 steps or more in bouts of ≥10 min or taking 1,500 steps or more in ≥100 steps/min was significantly and negatively associated with frailty. These foundings indicate that, in addition to participants taking 8,000 steps or more at least one day per week, step duration and intensity may also be important factors for preventing and improving frailty in older women.
