Methods : According to the method of Andrei Rogers, et al., the survey was conducted twice using a questionnaire covering questions as to ADL independence. The life table was prepared based on the transition probability of ADL by age for the subject populations to determine the average life expectancy and ALE. Results : Among the independent persons surveyed first, the average life expectancy was 18.7 and 23.5 years for 65-year-old males and females, respectively. When the ADL functional recovery rate was taken into account, the ALE stood at 17.2 and 20.7 years for males and females at the age of 65, respectively. Assuming that the difference between the average life expectancy and ALE represents the duration of dependence, it was calculated to be 1.5 and 2.8 years for 65-year-old males and females, respectively. Conclusion : Comparison of the average life expectancy and ALE with other areas already reported revealed that the inhabitants of the city studied had a long average life expectancy and ALE, and a comparatively short duration of dependence., 弘前医学. 58(1/2/3/4), 2007, p.1-10},
