To examine the relationship between current cigarette smoking patterns and three established risk factors for suicide using nationally representative data of high school students in the United States.
We analyzed cross-sectional data from the national Youth Risk Behavior Surveillance Survey (YRBSS)-United States, 2017. Multivariable, logistic regressions examined the association between 3 cigarette smoking behaviors [i.e., past 30-day cigarette (n = 13,731), frequent (n = 1,093) and heavy (n = 880) smoking] and 3 risk factors for suicidal outcomes [feeling sad or hopeless, suicidal ideation, suicide plan] assessed over the previous year.
Among high school cigarette smokers, smoking 11 or more cigarettes per day (i.e., heavy smoking) was associated with 3.43 (95% CI: 1.69, 6.94) greater odds of reporting feeling sad or hopeless, 2.97 (95% CI: 1.60, 5.51) greater odds of reporting suicidal ideations, and 2.11 (95% CI: 1.34, 3.32) greater odds of reporting having ever planned a suicide attempt, controlling for covariates.
Our study shows that it is not simply cigarette smoking, but heavy cigarette smoking that is a risk factor for suicidal outcomes among adolescents.
A comprehensive plan is needed to accommodate heavy adolescent smokers who are at increased suicidal risk.
利用美国全国高中生代表性数据，研究当前吸烟模式与自杀的三个既定风险因素之间的关系。
我们分析了来自全国青少年风险行为监测系统调查（YRBSS-美国，2017 年）的横断面数据。多变量逻辑回归检验了三种吸烟行为[即过去 30 天吸烟（n=13731）、频繁吸烟（n=1093）和重度吸烟（n=880）]与过去一年评估的自杀结果的三个风险因素[感到悲伤或绝望、自杀意念、自杀计划]之间的关联。
在高中吸烟的学生中，每天吸烟 11 支或以上（即重度吸烟）与报告感到悲伤或绝望的几率增加 3.43 倍（95%CI：1.69，6.94）、报告自杀意念的几率增加 2.97 倍（95%CI：1.60，5.51）、报告曾经计划自杀的几率增加 2.11 倍（95%CI：1.34，3.32），在控制了混杂因素后。
我们的研究表明，青少年自杀结果的风险因素不仅仅是吸烟，而是重度吸烟。
需要制定综合计划，以适应处于较高自杀风险的重度青少年吸烟者。
