We examined individual, friend or family, and community or tribe correlates of suicidality in a representative on-reserve sample of First Nations adolescents.
Data came from the 2002-2003 Manitoba First Nations Regional Longitudinal Health Survey of Youth. Interviews were conducted with adolescents aged 12 to 17 years (n=1125) from 23 First Nations communities in Manitoba. We used bivariate logistic regression analyses to examine the relationships between a range of factors and lifetime suicidality. We conducted sex-by-correlate interactions for each significant correlate at the bivariate level. A multivariate logistic regression analysis identified those correlates most strongly related to suicidality.
We found several variables to be associated with an increased likelihood of suicidality in the multivariate model, including being female, depressed mood, abuse or fear of abuse, a hospital stay, and substance use (adjusted odds ratio range=2.43-11.73). Perceived community caring was protective against suicidality (adjusted odds ratio=0.93; 95% confidence interval=0.88, 0.97) in the same model.
Results of this study may be important in informing First Nations and government policy related to the implementation of suicide prevention strategies in First Nations communities.
我们在原住民青少年的代表性保留地样本中，检查了个人、朋友或家人以及社区或部落与自杀意念相关的因素。
数据来自 2002-2003 年马尼托巴省原住民区域纵向青年健康调查。对马尼托巴省 23 个原住民社区中 12 至 17 岁的青少年（n=1125）进行了访谈。我们使用双变量逻辑回归分析来检查一系列因素与终生自杀意念之间的关系。我们对每个双变量水平上的显著相关因素进行了性别-相关因素交互作用分析。多变量逻辑回归分析确定了与自杀意念最相关的相关因素。
我们在多变量模型中发现了几个与自杀意念增加相关的变量，包括女性、情绪低落、遭受虐待或担心受虐待、住院和物质使用（调整后的优势比范围为 2.43-11.73）。在同一模型中，社区关怀被认为可以预防自杀（调整后的优势比=0.93；95%置信区间=0.88，0.97）。
本研究的结果可能对原住民和政府制定与在原住民社区实施自杀预防策略相关的政策具有重要意义。
