To determine the prevalence of suicidal ideation among Métis men and women (20-59 years) and identify its associated risk and protective factors using data from the nationally representative Aboriginal Peoples Survey (2006).
Secondary analysis of previously collected data from a nationally representative cross-sectional survey.
Across Canada, lifetime suicidal ideation was reported by an estimated 13.3% (or an estimated 34,517 individuals) of the total population of 20-to-59-year-old Métis. Of those who ideated, 46.2% reported a lifetime suicide attempt and 6.0% indicated that they had attempted suicide in the previous 12 months. Prevalence of suicidal ideation was higher among Métis men than in men who did not report Aboriginal identity in examined jurisdictions. Métis women were more likely to report suicidal ideation compared with Métis men (14.9% vs. 11.5%, respectively). Métis women and men had some common associated risk and protective factors such as major depressive episode, history of self-injury, perceived Aboriginal-specific community issues, divorced status, high mobility, self-rated thriving health, high self-esteem and positive coping ability. However, in Métis women alone, heavy frequent drinking, history of foster care experience and lower levels of social support were significant associated risk factors of suicidal ideation. Furthermore, a significant interaction was observed between social support and major depressive episode. Among Métis men, history of ever smoking was the sole unique associated risk factor.
The higher prevalence of suicidal ideation among Métis women compared with Métis men and the observed gender differences in associations with some associated risk and protective factors suggest the need for gender-responsive programming to address suicidal ideation.
利用具有全国代表性的原住民调查（2006年）数据，确定梅蒂斯族20至59岁男性和女性中自杀意念的患病率，并识别其相关风险因素和保护因素。
对先前从具有全国代表性的横断面调查中收集的数据进行二次分析。
在加拿大全国范围内，估计20至59岁的梅蒂斯族总人口中有13.3%（约34517人）报告有终生自杀意念。在有自杀意念的人群中，46.2%报告有过终生自杀未遂经历，6.0%表示在过去12个月内曾试图自杀。在所研究的司法管辖区内，梅蒂斯族男性的自杀意念患病率高于未报告原住民身份的男性。与梅蒂斯族男性相比，梅蒂斯族女性更有可能报告有自杀意念（分别为14.9%和11.5%）。梅蒂斯族女性和男性有一些共同的相关风险因素和保护因素，如重度抑郁发作、自我伤害史、感知到的特定原住民社区问题、离婚状况、高流动性、自评健康状况良好、高自尊和积极的应对能力。然而，仅在梅蒂斯族女性中，频繁大量饮酒、寄养经历史和较低水平的社会支持是自杀意念的显著相关风险因素。此外，观察到社会支持与重度抑郁发作之间存在显著交互作用。在梅蒂斯族男性中，曾经吸烟史是唯一独特的相关风险因素。
与梅蒂斯族男性相比，梅蒂斯族女性自杀意念患病率较高，且在一些相关风险因素和保护因素的关联方面存在性别差异，这表明需要开展针对性别的项目来解决自杀意念问题。
