Factors relating to frequency of falls in old-old community residents aged over 75 : Multivariate analysis using physical factors

Abstract

We analyzed the factors related to prevention against frequent falls in old-old residents aged over 75 and young-old residents aged from 65 to 74. Multiple regression analysis was performed using frequency of falls as a dependent variable with age, sex, anamneses, self-rating symptoms, muscle power, moving range of joints, pain of joints, walking capacity, bone density, blood pressure and other factors as independent variables. The results were as follows. The factors significantly related to frequency of falls in old-old residents aged over 75 were right Kemp's Test (Positive) (β=0.302), systolic blood pressure (β=0.213) and right hand grip power β=-0.191). The factors significantly related to frequency of falls in young-old residents aged from 65 to 74 were 10m walking speed β=-0.344) and left arm abductor power β=0.199).
