title: [Participant characteristics and intervention effects of a program to improve the physical function in community-dwelling frail elderly subjects].
abstract: OBJECTIVE
  To examine the intervention effects of a physical function improvement program for community-dwelling frail elderly subjects.
  
  
  METHODS
  The subjects included 309 participants (108 males, 224 females) who took part in "Iki Iki Health Classes," an exercise training program for frail elderly individuals conducted over three years from April 2008 to March 2011. The average participant age was 75.4±5.8 years in the males and 74.6±5.6 years in the females.
  
  
  RESULTS
  Many participants had bone and joint disease with hypertension. The proportion of those with a history of falls (49.0%) was high. Significant improvements from the program were seen in the motor function and in the total scores for the Kihon checklist, grip strength, standing on one leg, timed up-and-go test (TUG), 5-m walking time and 5-m walking maximum time, fear of falling (77.5→70.1%) and subjective health ("good/well good/usually," increased from 73.6% to 89.1%). A new care-needs certification was issued in 21.6% of the subjects during the period spanning to March 31, 2013. A logistic regression analysis revealed that the deterioration of subjective health was significantly related to the presence of risk factors for new care-needs certification (odds ratio and 95% confidence interval: 4.99 (1.04-23.9), p=0.04).
  
  
  CONCLUSIONS
  These results suggest that the interventions used in the program to improve the physical function contributed to improving the subjects' mental and physical functions. We speculate that whether improvements in subjective health are linked to roles in normal life and/or social activity participation is important for care prevention.
