To determine the influence of individual and area-level characteristics associated with suicide in older adults.
This study used two complementary data sources. The first used administrative data from the Quebec Coroner's office and included information on suicide deaths in older adults aged 65years and over who died by suicide between 2000 and 2005 (n=903 persons). The second data source, which was used to identify the control group, came from a longitudinal study on seniors' health that was conducted in Quebec between 2004 and 2005 (n=2493 persons). Logistic regression analyses were used to test for associations between suicide and individual and area-level level characteristics.
Suicide was associated with male gender, age, the presence of a physical and mental disorder and the use of health services. At the area-level level, suicide was associated with a higher population density, concentration of men, lower rates of education and higher rate of unemployment. Gender specific analyses also showed different patterns of associations on suicide risk.
Suicide in older adults is associated with area-level and individual characteristics. This suggests that policies targeting only one level of risk factors are less likely to significantly influence suicide among this population.
确定与老年人自杀相关的个体和地区层面特征的影响。
本研究使用了两个互补的数据源。第一个使用了魁北克死因裁判官办公室的行政数据，包括2000年至2005年间65岁及以上自杀死亡的老年人的信息（n = 903人）。第二个数据源用于确定对照组，来自2004年至2005年在魁北克进行的一项关于老年人健康的纵向研究（n = 2493人）。逻辑回归分析用于检验自杀与个体和地区层面特征之间的关联。
自杀与男性性别、年龄、身心障碍的存在以及医疗服务的使用有关。在地区层面，自杀与较高的人口密度、男性集中度、较低的教育水平和较高的失业率有关。按性别进行的分析还显示了自杀风险关联的不同模式。
老年人自杀与地区层面和个体特征有关。这表明仅针对一个风险因素层面的政策不太可能对该人群的自杀产生显著影响。
