Background: Suicide is the first leading cause of death
among teenagers in Korea, and smoking is reported to
be one of the risk factors for suicide. The purpose of this
study is to investigate the relationship between smoking
and smoking amount and suicidal behavior using data from
the Korea Youth Risk Behavior Web-based
Survey (KYRBS).
Methods: Using the 12th KYRBS 2016, we surveyed
smoking, smoking amount, suicidal ideation, suicidal
planning,
and suicidal attempt of adolescents. And a total of 65,528
respondents were divided into current smoker,
former smokers, and non-smoker, and 4,012 smokers were
classified into ≤9 cigarettes/day group, 10-19 cigarettes/
day group, and ≥20 cigarettes/day group according to the
amount of smokers. We analyzed the relationship
between smoking and smoking amount and suicidal
ideation, suicidal planning, and suicidal attempt
using multivariate logistic regression analysis.
Results: As a result of adjusting for all confounding
variables, the current smoker has an odds ratio of 1.143
(confidence interval 1.020-1.281) with suicidal ideation
compared to non-smoker and the odds ratio of suicidal
planning and suicidal attempt is also statistically significant,
respectively. And the odds ratio of all suicidal behaviors
was significantly higher in ≥20 cigarettes/day group than in
≤9 cigarettes/day group, respectively.
Conclusions: We found that smoking and smoking amount
was related to suicidal ideation, suicidal planning,
and suicidal attempts in adolescents. Therefore, suicidal
prevention strategies considering this relationship
should be established.
