[Mortality patterns of Taiwan aborigines due to accidents]

The purpose of this investigation was to study ethnic differences in mortality patterns due to accidents in the various aboriginal areas of Taiwan. Mortality data was collected from the National Health Department. To compare the accident mortality of aborigines with that of the general population of Taiwan, and then calculated standardized mortality ratios for accidents in the various aboriginal groups by using the cause specific accident mortality of the general population as standardized mortality and found that mortality in Taiwan between 1971 and 1990 was 60.1 per hundred thousand due all causes of injuries 72.2 (102.2 for males and 39.5 for females). The same figures for the aborigines were 194.9 (274.1 for males and 98.7 for females), respectively. The leading causes of accidental death among the aborigines were motor vehicle accidents, suicide, drowning, accidental falls for males and suicide, motor vehicle accidents and non-drug poisoning for females. Our investigations show that the standardized mortality ratio due to accidents in the aboriginal areas is two to three times higher than that in the general population of Taiwan. These figures were differences among the aboriginal tribes, despite similarities in medical care, environmental and economic circumstances. Mortality due to accidents, especially due to suicide and poisoning, in the Atayal and Bunun tribes were particularly higher than in other tribes. Thus, the risk of an accident in these regions may be associated not only with the environment and the lack of medical resources, but with some socio-cultural factors.
