To describe changes of the epidemiological profile of suicides in Hong Kong, and the burden of suicides in terms of years of life lost between 1981 and 2001.
Retrospective study.
Hong Kong.
Data on registered deaths of the Hong Kong population from 1981 to 2001 were retrieved from records of the Census and Statistics Department of the Government of the Hong Kong Special Administrative Region.
Crude, standardised, age- and sex-standardised suicide rates; years of life lost; suicide method used; and rank among leading causes of death.
Suicide ranked sixth in the leading cause of deaths and represented about 3% of all deaths each year. The suicide rate has increased from 9.6 per 100000 to 15 per 100000 between 1981 and 2001. The total years of life lost due to suicide increased by 96.0%, from about 9900 years in 1981 to 19 400 years in 2001, whereas the figure for all causes of death decreased by 14.0%, from 274600 years to 236700 years. The total share of years of life lost attributable to suicide deaths has increased from 3.6% to 8.1% and is still increasing, especially among the middle age-groups (30-59 years). The use of charcoal burning as a suicide method has increased from 6.0% before 1998 to more than 28.0% in 2001.
The burden on the years of life lost due to suicide is underestimated and overlooked. The increase of suicides in recent years has had a significant impact on the years of life lost and can be used as a useful indicator of performance in Hong Kong.
描述香港自杀流行病学特征的变化，以及1981年至2001年期间因自杀导致的寿命损失负担。
回顾性研究。
香港。
从香港特别行政区政府统计处的记录中检索了1981年至2001年香港人口登记死亡数据。
粗自杀率、标准化自杀率、年龄和性别标准化自杀率；寿命损失年数；自杀方式；以及在主要死因中的排名。
自杀在主要死因中排名第六，每年约占所有死亡人数的3%。1981年至2001年期间，自杀率从每10万人9.6例增至每10万人15例。因自杀导致的总寿命损失年数增加了96.0%，从1981年的约9900年增至2001年的19400年，而所有死因的这一数字下降了14.0%，从274600年降至236700年。自杀死亡导致的寿命损失年数所占总份额从3.6%增至8.1%，且仍在增加，尤其是在中年人群（30至59岁）中。使用烧炭作为自杀方式的比例从1998年前的6.0%增至2001年的逾28.0%。
因自杀导致的寿命损失负担被低估和忽视。近年来自杀率的上升对寿命损失年数产生了重大影响，可作为香港一项有用的绩效指标。
