[Secular trends in mortality for cerebrovascular diseases in Taiwan (1959-1989)].
Cerebrovascular disease (CVD) is predominantly a disease of the elderly, and its morbidity effects increase with advancing age. In Taiwan, the increasing proportion of the elderly, as a result of medical progress and improved health care in the past 30 years, is largely responsible for the apparent increase in the number of CVD deaths. From 1963 to 1981, CVD was the leading cause of death. The crude mortality rate (CMR) and age-specific mortality rate (ASMR) of CVD by sex were derived from vital statistical data from 1959 to 1989 in Taiwan. The age-adjusted mortality rate (AAMR) using the standard world population of WHO and the cumulative mortality rate (CUMR) from birth to less than 80 years of age were calculated. Before 1983, the total number of CVD deaths had increased steadily for 30 years. In 1989, the CMR was 76.6/100,000 in men and 67.7/100,000 in women. The highest AAMR was 158.5/100,000 in 1973 for men and 130.2/100,000 in 1972 for women, and the lowest AAMR was 91.3/100,000 in 1989 for men and 81.1/100,000 in 1972 for women. The highest CUMR was 26.3% in 1968 for men and 20.8% in 1972 for women, and the lowest CUMR was 14.5% in 1989 for men and 13.6% in 1989 for women. The AAMR and CUMR for both sexes reached a maximum in 1972 and began to decline thereafter. The declines in AAMR and CUMR were averaging 2%/yr for both sexes after 1972 and were averaging 5%/yr for men and 4%/yr for women after 1983. This declining trend in CVD deaths in Taiwan began later and has been slower than similar trends in Japan and the U.S.
