Effects of long-term exercise class on prevention of falls in community-dwelling elderly: Kahoku longitudinal aging study

Background: We intended to compare the effect on preventing falls between the subjects participating and not participating in exercise classes over 8 years of follow LIP in all the community-dwelling elderly in Kahoku Town, Kochi Prefecture, Japan. Methods: We compared falling state both in 1993 and 2001 between 119 participants (male : female ratio, 51:68; mean age, 72.5 years) in exercise class during the 8-year period from 1993-2001, and 878 non-participants (M : F ratio, 243:635; mean age, 73.4years). We assessed the long-term effects of participating in exercise classes on preventing falls via multivariate, longitudinal analysis. Results: Only participation in both the 1993-1995 period and 1996-2001 one was a significantly independent contributing factor for prevention of falls even after the adjustment for age, sex, activities of daily living, depression scale and presence/absence of oral drugs (odds ratio, 0.20; P = 0.007). Although it failed to reach significance in this study, recent and continuing exercise was Supposed to be effective for prevention of falls. Conclusion: Unlike a short program, long-continuing exercise is effective in preventing falls of community-dwelling elderly for a long time after the adjustment of age, activities of daily living, depression and other confounding variables.
