韓國人 期待餘命의 限界推定에 관한 研究 = A Study on the Estimation of Limits to Life Expectancy

다국어 초록 (Multilingual Abstract)

The purpose of this study is to estimate limits of Korean life expectancy at birth by 'Gompertz growth curve Model', 'Cause-Elimination Model' and Multidimensional models of Senescence and Mortality'.
Data used in Gompertz curve were obtained from all life tables published from 1905 to 1990 in Korea, and life expectancies at birth of eighteen groups were selected at five-year interval in consideration of time-series changes. Data used in Cause-Elimination Model are 'Causes of Death statistics in 1991' published in 1992 by National Bureau of Statistics of Korea and 'life table of 1989' published in 1990 by National Bureau of Statistics, Economic Planning Board of Korea. The materials are all classifiable death data, 119,253 cases of male and 82,420 cases of female, which is from 1991 Causes of Death statistics. The cases of death analyzed belong to one of 8 categories; i.e., Infectious and Parasitic Diseases(001-139; with notation of Infectious Diseases), Malignant Neoplasms(140-208), Hypertensive Diseases(401-405), Ischemic Heart Diseases and Diseases of Pulmonary Circulation and Other Forms of Heart Diseases (410-429 ; with notation of Heart Disease), Cerebrovascular Diseases(430-438), Chronic Liver Diseases and Cirrhosis(571; with notation of Liver Diseases), Injury and Poisoning(800-999) and all other disease. Data used in 'Multidimensional models of senescence and mortality' were life table of 1989 published by National Bureau of statistics, Economic Planning Board of Korea and life table of 1970,1978-79,1983, 1985 and 1987.
The major findings may be summarised as follows:
1. Estimate equations of Gompertz growth curve using life expectancy at birth during the 1905-1990 period are as the following.
Male : y = 88.047697 × (0.199690)0.903381x
Female : y = 95.632828 × (0.190219 )0 897553x
Limits of life expectancy at birth, which were estimated by Gompertz growth curve, are 88.05 for male and 95.63 for female.
2. The effect on life expectancy at birth of eliminating all causes of death is 14.04 years(for male) and 10.86 years(for female). Astonishingly, eliminating the malignant neoplasms increase life expectancy at birth by 2.85 years for male and 2.03 years for female in 1991. In table 8 we show the effect on life expectancy at birth of separately eliminating each of the 8 categorical causes of death. The theoretical limit to life expectancy by Cause-Elimination Model is 80.96 for male and 85.82 for female.
3. If the same rate of delay [0.376year(male), 0.435 year (female) per calendar year] continued, then life expectancy at birth would reach 74.82(male) years and 84.10(female) years in 2010. With 14.04-years(male) and 10.86-years(female) effect attributable in 2010 would be 88.86 years(male) and 94.96(female) years.
4. 'Multidimensional models of senescence and death' permits calculations of the value of the attribution coefficient (B), the percent of loss per year of physiologic function. The results of Ro and B during the 1970-1989 period are listed in table 9. Estimate of limit to Korean life expectancy at birth by 'multidimensional models of senescence and death' is 99.47 years for male and 104.74 years for female in 1989.
