title: [Comprehensive health examination ("Otasha-Kenshin") for the prevention of geriatric syndromes and a bed-ridden state in the community elderly. 1. Differences in characteristics between participants and non-participants].
abstract: OBJECTIVE
  We conducted a comprehensive mass health examination for elderly subjects aged 70 or above, living in the community, to assess early deterioration to long-term care conditions and promote healthy and successful aging ("Otasha-Kenshin"). In this study, we clarified characteristic differences between participants and non-participants.
  
  
  METHODS
  A mass health examination was offered in October 2001 to 863 community elderly, including individuals suffering from falls (and fractures), incontinence, malnutrition, depression, mild cognitive impairment and less of functional capacity. Among the total, 438 (50.8%) opted for the "Otasha-Kenshin" examination. Differences in characteristics between the participants and non-participants were examined, parameters including sex and age distribution, self-rated health, functional capacity by the TMIG Index of Competence, depressed status by the General Health Questionnaire (GHQ), subjective well-being by the Philadelphia Geriatric Center Morale Scale: A revision (PGC-MS), frequency of falls, and prevalence of chronic diseases. The comparison was based on the results of measurements from the final survey conducted in 2000.
  
  
  RESULTS
  1) The participation rate in the "Otasha-Kenshin" was 49.0% in males and 51.0% in females. The average age was 75.3 year olds in participants and 76.4 in non-participants, the difference being significant (t = 3.97, P < 0.0001). 2) Non-participants had a significantly lower level of self-rated health than participants. 3) There was no significant difference in hand grip strength between participants and non-participants. 4) Non-participants showed significantly lower level of functional capacity and subjective well-being, and they were more likely to be in a depressed state than participants. 5) There was no significant difference in fall rate between participants and non-participants. 6) The prevalence of hypertension and diabetes (found in more than 5% among the subjects surveyed in 2000) was not significantly different between participants and non-participants.
  
  
  CONCLUSIONS
  With aging of society, new and specialized health maintenance systems for the elderly are essential, both for the prevention of deterioration to a long-term care condition (a bed-ridden status) and for the promotion of successful aging with autonomy. Participants in "Otasha-Kenshin" appear to be healthier and more independent than non-participants who were more frail and at higher risk group of a long-term care condition and a bed-ridden status. The major reason for non-participation in the health examination found in this study was subjective or mental deterioration rather than the presence of chronic illness or any geriatric syndrome per se. Frail elderly people like the non-participants in this study should be encouraged and mentally supported to avoid aggravation of their health status through intensive or specialized health surveillance system such as home-visit nursing.
