The incidence rate of suicidal ideation among current and former smokers versus never smokers is not known. In this study, the age-adjusted incidence of suicidal ideation was highest among current smokers, followed by former, then never smokers. The adjusted hazard for suicide ideation was 2.22 (95%CI = 1.48, 3.33) and 1.19 (95%CI = 0.78, 1.82) for current and former smokers, respectively, compared to never smokers. Results indicate that current smokers have increased risks of suicidal ideation above and beyond the risk for never and former smokers regardless of age, gender, history of depressive disorder or anxiety symptoms, and alcohol abuse/dependence. Smoking cessation might be beneficial for some suicide prevention efforts.
目前和既往吸烟者与从不吸烟者相比,自杀意念的发生率尚不清楚。在这项研究中,调整年龄后的自杀意念发生率以当前吸烟者最高,其次是既往吸烟者,然后是从不吸烟者。与从不吸烟者相比,当前吸烟者和既往吸烟者的自杀意念调整后危险比分别为 2.22(95%CI=1.48, 3.33)和 1.19(95%CI=0.78, 1.82)。结果表明,当前吸烟者的自杀意念风险高于从不吸烟者和既往吸烟者,无论年龄、性别、抑郁障碍或焦虑症状史以及酒精滥用/依赖史如何。戒烟可能对某些预防自杀的努力有益。
