FALL-RELATED FACTORS TO TARGET IN COMMUNITY-BASED INTERVENTIONS FOR PREVENTION OF FALLS / 体力科学

ABSTRACT

Fall-related factors (FRFs) are classified into intrinsic factors and extrinsic factors. Intervention programs, which focused on modifiable factors (MFs) among FRFs have been designed to prevent falls. The purpose of this study was to identify easily-measurable intrinsic MFs for falls and recurrent falls. Cross-sectional analysis was carried out on the data from 483 community-dwelling older adults, aged 65-92 years (73.7 ± 5.9 yr, 138 men, 345 women). We measured history of falls in the past year and 7 domains of FRFs. Of these, 20 items were selected as MFs. Analyses of FRFs and MFs were conducted by comparing (separated by sex) those who did not report a fall with those who reported any number of falls, and those who reported no falls or one fall with those who reported recurrent falls. Using the significant items as independent variables, multiple logistic regression analysis with forward selection method was performed. The prevalence of falls and recurrent falls was in men, 24.6% and 14.5%; in women, 26.7% and 12.5%. There were no significant differences in prevalence of falls or recurrent falls between genders. The following items were selected as the MFs most strongly associated with falls climbing 10 steps with difficulty and tandem walk; and associated with recurrent falls climbing 10 steps with difficulty, sit and reach, and tandem walk. These results are useful in determining the focus of fall prevention programs to be used in future community-based interventions.
