OBJECTIVE
Both the suicide rate and unemployment rate have showed an upward trend in Taiwan since 1994. This study aimed to explore the association between the suicide rate and the unemployment rate. This information is useful in developing specific suicide prevention strategies related to unemployment.
METHODS
All the cases of suicide by those aged 15 years and above during 1978-2006 in Taiwan (n = 74,064) were included in this study. Time series models were used to analyze the monthly age-standardized suicide rate by gender and age-subgroup (15-24, 25-44, 45-64, and 65+).
RESULTS
With regard to the age range and gender subgroup, the association between age-standardized suicide and the unemployment rate was comparatively high for males and those aged from 45 to 64 years. Among males and those aged from 45 to 64 years, a 1% increase in the absolute unemployment rate was associated with a 4.9% (95% confidence interval: 1.7-8.2) increase in the relative age-standardized suicide rate in the monthly average from 1978 to 2006 in Taiwan.
CONCLUSIONS
Suicide prevention strategy for the unemployed should be more focused especially on males aged from 45 to 64 years in Taiwan.
目的
自 1994 年以来，台湾的自杀率和失业率均呈上升趋势。本研究旨在探讨自杀率与失业率之间的关系。这些信息有助于制定与失业相关的特定自杀预防策略。
方法
本研究纳入了 1978 年至 2006 年期间台湾年龄在 15 岁及以上人群的所有自杀案例（n=74064）。采用时间序列模型分析了按性别和年龄亚组（15-24 岁、25-44 岁、45-64 岁和 65 岁及以上）划分的每月标准化自杀率。
结果
就年龄范围和性别亚组而言，标准化自杀率与失业率之间的关联在男性和 45-64 岁年龄组中相对较高。对于男性和 45-64 岁年龄组而言，1978 年至 2006 年期间，每月平均绝对失业率每增加 1%，相对标准化自杀率就会增加 4.9%（95%置信区间：1.7-8.2）。
结论
台湾应更加关注失业人群的自杀预防策略，尤其是针对 45-64 岁的男性。
