Although mortality measures such as crude and age-adjusted death rates have been used traditionally to determine the relative importance of the various causes of death, it is obvious for them to suffer from the underlying disease process of the elderly because most deaths occur among persons in older age groups. alternative measures have been proposed to reflect the mortality trends of younger age groups and one of them is the years of potential life lost(YPLL). This study was carried out to determine the temporal trends of YPLL of the selected´, causes of death during the period of 1983-1992 as well as the magnitudes of them in Korea using the Annual Reports on the Cause of Death Statistics published by the National Statistical Office. YPLL were calculated by the method of the Centers for Disease Control over the age ranging birth to 65 years using age-specific numbers of classifiable causes of death tabulated into the 307 ICD-9 rubrics which are represented more or less 90% of all death certificates in Korea. Temporal trends were assessed by direct age-adjusted YPLL rates using the mean of census data of 1985 and 1990 as a reference population.
The YPLL of 1,734,456 in males and 1,022,422 in females were lost in 1983 and 1,011.841 and 657,464 were in 1992, respectively. Unintentional injuries were the leading cause of YPLL accounting for 23_4%(405,806 years) of all YPLL and followed by malignant neoplasms 10.7%(185,159 years), diseases of the heart 8.5yD(148,259 years), cerebrovascular diseases 5.5%(96.050 years), chronic liver diseases and cirrhosis 5.3%(91,175 years) in males of 1983. And in females, malignant neoplasms were the leading cause of YPLL accounting for 13.4%(136. 977 years) of all YPLL and unintentional injuries 11.9%(122,050 years), diseases of the heart 11.3%(115,257 years), pneumonia and influenza 8.1%(83.020 years), cerebrovascular diseases 6.5%(66,333 years), tuberculosis 5.5%(55,&04 years). Unintentional injuries were accounted for 36.6%(550,040 years) of all YPLL and followed by malignant neoplasms 15.5%(232,969 years), chronic liver diseases and cirrhosis 8.2%(122,945 years), diseases of the heart 5.8%(87,018 years), cerebrovascular diseases 5.0%(75,341 years) in males of 1992. In females, unintentional injuries were the leading cause of YPLL and accounted for 23.5%(154,614 years) of all YPLL and followed by malignant neoplasms 19.9%(130,546 years), cerebrovascular diseases 7.3%(47,72.5 years). diseases of the heart 6.6%(43,374 years), suicide and homicide 5.1%(33,596 years). The age-adjusted YPLL rates per 1,000 persons were 90.4 for all causes in 1983 and 70.1 in 1992 resulting in 22.5 percent decrease. In females, they decreased 53.3 to 39.3 resulting in ´26.3 percent change. YPLL were decreased during the period of 1983-1992 in most of the causes except congenital anomalies aril prematurely in both sexes. Malignant neoplasms showed no change in males but 205% decrease(7.8 persons in 198 to 6.2 persons in 19.92) in females. Male-female ratios were more than I in most causes except pneumonia and influenza in 1983 and prematurity in 1992. These results suggest that YPLLL reflect different perspectives from the conventional mortality measures and public health interventions be 7necessary to degrease the increasing proportion of unintentional injuries accounting for YPLL for all causes in both sexes.
