OBJECTIVES: Little research has evaluated changes in the association between area deprivation and suicidal behaviour over time. This study investigated patterns in suicide attempts and suicide mortality according to material deprivation in the province of Québec, Canada between 1990 and 2005. STUDY DESIGN: Ecological analysis. METHODS: Data on suicide attempts were extracted from the hospital discharge summary database (n=47,516) and data on suicides were extracted from the Québec death file (n=20,851). Gender- and age-specific (10-24, 25-44, 45-64 and > or = 65 years) suicide attempt and mortality rates were calculated for four time periods (1990-1993, 1994-1997, 1998-2001 and 2002-2005) for the entire Québec population aged 10 years and older residing in 162 communities ranked by decile of material deprivation. Absolute and relative measures of inequality were calculated to summarize differences between the most and least materially deprived areas. Commonly used methods of suicidal behaviour were examined. RESULTS: Differentials in suicide attempt hospitalization between the most and least deprived areas were present for all age groups, and these decreased slightly among males and increased among females over time. Inequalities in suicide attempts were greatest among young adults (age 25-44 years) for both genders, and were smallest among the elderly (> or = 65 years). For suicide mortality, differentials increased among females but not males; these differentials were greatest among males and 25-44 year olds, and smallest among the elderly. Differentials in commonly used methods were evident for poisoning hospitalizations in both genders and for hanging deaths among males. CONCLUSIONS: In Québec, differences in suicide attempts and mortality between the most and least materially deprived areas persisted or even increased over time. Inequalities were more pronounced for suicide attempts than for suicide mortality, and were greatest among adults of working age. Strategies to reduce socio-economic differences in suicidal behaviour may be important.
目的：很少有研究评估随着时间的推移，地区贫困与自杀行为之间关联的变化。本研究调查了 1990 年至 2005 年间加拿大魁北克省根据物质贫困状况自杀未遂和自杀死亡率的模式。 研究设计：生态分析。 方法：从医院出院摘要数据库中提取自杀未遂数据（n=47516），从魁北克死亡档案中提取自杀数据（n=20851）。为整个魁北克省 10 岁及以上、居住在 162 个社区的人群（按物质贫困程度分为十分位数），计算了四个时期（1990-1993 年、1994-1997 年、1998-2001 年和 2002-2005 年）的性别和年龄特定（10-24 岁、25-44 岁、45-64 岁和≥65 岁）自杀未遂和死亡率。计算了绝对和相对不平等措施，以总结最贫困和最不贫困地区之间的差异。研究了自杀行为的常用方法。 结果：在所有年龄组中，最贫困和最不贫困地区之间的自杀未遂住院率存在差异，并且随着时间的推移，男性略有下降，女性略有上升。自杀未遂的不平等在年轻成年人（25-44 岁）中男女都最大，在老年人（≥65 岁）中最小。对于自杀死亡率，女性的差异增加，但男性没有增加；这些差异在男性和 25-44 岁的人群中最大，在老年人中最小。在男女两性的中毒住院和男性的上吊死亡方面，常用方法的差异明显。 结论：在魁北克，最贫困和最不贫困地区之间的自杀未遂和死亡率差异持续存在，甚至随着时间的推移而增加。不平等现象在自杀未遂方面比自杀死亡率更为明显，在工作年龄的成年人中最为严重。减少自杀行为的社会经济差异的策略可能很重要。
