背景：自杀在韩国和日本都是导致死亡的主要原因之一。目的：本研究旨在比较过去二十年（1985-2006）自杀的描述性流行病学，并探讨与两国自杀不同分布相关的条件。方法：年龄标准化自杀率来源于OECD 2009年健康数据。各年龄组按年龄划分的自杀率是根据世卫组织死亡率数据库计算的。根据ICD-10确定自杀方式。结果：从1980年到2000年，日本的自杀率一直高于韩国。但是，从20世纪90年代中期开始，韩国的自杀率急剧上升，最终超过了日本。韩国的年龄标准化自杀率从1985年的10.2人（每10万人）上升到2006年的21.5人，而日本从18.4人小幅上升到19.1人。自杀率最高的年龄段是45-64岁的日本男性和64岁以上的韩国男性。韩国女性的老年自杀率明显上升。日本的男女比例上升，韩国的男女比例下降。韩国的自杀方式是上吊和农药中毒，日本的自杀方式是上吊。由于观察数量有限，无法对特定风险因素进行假设检验。结论：两国自杀率的年龄和性别分布差异很大。两国的终身福利保障和韩国的农药管制将有助于减少两国自杀死亡率的负担，即使社会价值观无法在短时间内改变。
Background: Suicide is one of the leading causes of mortality in both South Korea and Japan. Aims: The study aims to compare the descriptive epidemiology of suicide over the last two decades (1985-2006) and to explore the conditions associated with the different distribution of suicides in both countries. Methods: Age-standardized suicide rates were obtained from the OECD Health Data 2009. Age-specific suicide rates for the age groups were calculated from the WHO Mortality Database. Suicide methods were identified based on ICD-10. Results: Through 1980-2000, Japan showed consistently higher suicide rates compared to Korea. However, from the mid-1990s, Korea showed an acute increase of suicides and finally surpassed Japan; the age-standardized suicide rate of Korea increased from 10.2 (per 100,000) in 1985 to 21.5 in 2006, while it slightly increased from 18.4 to 19.1 in Japan. The highest age-specific suicide rate was observed among Japanese men aged 45-64 years and Korean men aged over 64 years. The increase of elderly suicides among Korean women was notable. The gender ratio increased in Japan and decreased in Korea, respectively. The preferred suicide methods were hanging and pesticide poisoning in Korea and hanging in Japan. Because of the limited number of observations, hypothesis testing of specific risk factors was not possible. Conclusions: Age and gender distribution of suicide rates differed considerably between the two countries. Welfare protection throughout the life course in both countries, and pesticide regulation in Korea would be helpful in reducing the burden of suicide mortality in both countries, even if the social values could not be changed in a short time.
