We address whether smoking is related to suicidal ideation in teens and whether there is evidence of a causal pathway.
We use data from the 2002 National Annenberg Survey of Youth and employ multivariate logistic regression to model each teen's risk of suicidal ideation as a function of self-report of depressive symptoms, own smoking, parent smoking, and demographic and household income variables.
Individuals reporting depressive symptoms have an increased risk of suicidal ideation (odds ratio [OR] = 13.13; 95% CI = 5.98-28.81). Relative to teens who do not smoke and whose parents do not smoke, teens who smoke and do not have a parent who smokes have increased risk of suicidal ideation (OR = 8.10; 95% CI = 2.88-22.80), whereas those with a parent who smokes do not have a statistically significant increased risk of suicidal ideation regardless of teen smoking behavior.
Relative to teens who do not smoke and do not have parents who smoke, suicidal ideation risk is increased in teens who smoke only if they do not have a parent who smokes. We find evidence that the smoking and suicidal ideation of the teens is likely due to common psychosocial causes rather than a causal pathway from smoking to suicidal ideation.
我们探讨青少年吸烟与自杀意念之间的关系，以及是否存在因果关系。
我们使用 2002 年全国安纳伯格青少年调查的数据，采用多元逻辑回归模型，将每个青少年自杀意念的风险作为其报告的抑郁症状、自身吸烟、父母吸烟、人口统计学和家庭收入变量的函数进行建模。
报告有抑郁症状的个体自杀意念的风险增加（优势比[OR] = 13.13；95%置信区间[CI] = 5.98-28.81）。与不吸烟且父母不吸烟的青少年相比，仅吸烟且父母不吸烟的青少年自杀意念的风险增加（OR = 8.10；95% CI = 2.88-22.80），而无论青少年的吸烟行为如何，有吸烟父母的青少年自杀意念的风险没有统计学上的显著增加。
与不吸烟且父母不吸烟的青少年相比，仅吸烟且父母不吸烟的青少年自杀意念的风险增加。我们的研究结果表明，青少年的吸烟和自杀意念可能是由于共同的心理社会原因，而不是吸烟导致自杀意念的因果关系。
