Summary

Okinawan centenarians show increased dementia and disability, with significant declines in Activities of Daily Living (ADL) scores observed between the 1970s and 1990s. Declines were more pronounced in institutionalized individuals, with physical function decreasing more in institutions and cognitive function declining more in home settings.

Area of Science:

  • Gerontology and Geriatric Medicine
  • Public Health and Epidemiology
  • Sociomedical Sciences

Context:

  • Longitudinal studies of Okinawan centenarians since 1976 reveal changing health profiles.
  • A significant increase in the centenarian population in Okinawa has been observed.
  • Recent trends indicate a rise in dementia and disability among this supercentenarian group.

Purpose:

  • To statistically analyze the changes in Activities of Daily Living (ADL) scores among Okinawan centenarians over three decades.
  • To compare the decline in physical and cognitive functions between home-dwelling and institutionalized centenarians.
  • To assess the impact of lifestyle and social welfare on the health status of the oldest old.

Summary:

  • Activities of Daily Living (ADL) scores were assessed in 43 subjects (1970s), 99 (1980s), and 109 (1990s) centenarians in Okinawa.

  • A more marked decline in total ADL scores was observed between the 1970s and 1980s compared to the 1980s and early 1990s.
  • Physical function declined more in institutionalized centenarians, while cognitive function declined more in home-living centenarians.

    • Impact:

    • Findings highlight the increasing burden of care and support needs for a growing supercentenarian population.
    • The study provides insights into differential aging trajectories based on living environment (home vs. institution).
    • Understanding these trends is crucial for developing targeted interventions and improving quality of life for the extremely elderly.
