To examine associations between health risk behaviours and suicidal ideation and attempts in Canadian adolescents aged 12 to 13 years. Young adolescents think about and attempt suicide. However, most existing research on suicide has been conducted on individuals aged 15 years and older.
The present study examined a nationally representative Canadian sample of adolescents aged 12 to 13 years (n=2090). Health risk behaviours included disruptive (shoplifting, physical fighting, damaging property, fighting with a weapon, carrying a knife, and gambling), sexual (petting below the waist and sexual intercourse), and substance use behaviours (smoking cigarettes, consuming alcohol, marijuana or hash, and glue or solvents). Unadjusted and adjusted (for all significant health risk behaviour and psychiatric symptoms) models were tested.
All health risk behaviours were common among male and female adolescents. In unadjusted models, almost all health risk behaviours were associated with suicidal ideation and attempts among adolescent boys. In adjusted models, only damaging property, sexual intercourse, and smoking cigarettes remained statistically associated with suicidal ideation, while smoking cigarettes and using marijuana or hash remained statistically associated with suicide attempts among adolescent boys. All health risk behaviours were statistically associated with suicidal ideation and attempts among female adolescents in unadjusted models. In adjusted models, only carrying a knife remained statistically associated with suicidal ideation, while shoplifting and gambling remained statistically associated with suicide attempts among adolescent girls.
Health risk behaviours among young adolescents are associated with suicidal ideation and attempts among young adolescents. Recognizing health risk behaviours among young adolescents may be one means of understanding who among them is at increased risk of suicidality.
研究12至13岁加拿大青少年的健康风险行为与自杀意念及自杀未遂之间的关联。青少年会思考并尝试自杀。然而，现有的大多数关于自杀的研究都是针对15岁及以上的个体进行的。
本研究调查了一个具有全国代表性的12至13岁加拿大青少年样本（n = 2090）。健康风险行为包括破坏性行为（行窃、肢体冲突、破坏财物、持械斗殴、携带刀具和赌博）、性行为（腰部以下抚摸和性交）以及物质使用行为（吸烟、饮酒、吸食大麻或哈希什、胶水或溶剂）。对未调整模型和调整模型（针对所有显著的健康风险行为和精神症状）进行了测试。
所有健康风险行为在青少年男性和女性中都很常见。在未调整模型中，几乎所有健康风险行为都与青少年男性的自杀意念和自杀未遂有关。在调整模型中，只有破坏财物、性交和吸烟与自杀意念在统计学上仍有关联，而吸烟和使用大麻或哈希什与青少年男性的自杀未遂在统计学上仍有关联。在未调整模型中，所有健康风险行为都与青少年女性的自杀意念和自杀未遂在统计学上有关联。在调整模型中，只有携带刀具与自杀意念在统计学上仍有关联，而行窃和赌博与青少年女性的自杀未遂在统计学上仍有关联。
青少年的健康风险行为与青少年的自杀意念和自杀未遂有关。识别青少年中的健康风险行为可能是了解哪些青少年自杀风险增加的一种方式。
