This study examined the association between early initiation of problem behaviors (alcohol drinking, cigarette smoking, and sexual intercourse) and suicidal behaviors (suicidal ideation and suicide attempts), and explored the effect of concurrent participation in these problem behaviors on suicidal behaviors among Korean adolescent males and females.
Data were obtained from the 2006 Korean Youth Risk Behavior Survey, a nationally representative sample of middle and high school students (32,417 males and 31,467 females) in grades seven through twelve. Bivariate and multivariate logistic analyses were conducted. Several important covariates, such as age, family living structure, household economic status, academic performance, current alcohol drinking, current cigarette smoking, current butane gas or glue sniffing, perceived body weight, unhealthy weight control behaviors, subjective sleep evaluation, and depressed mood were included in the analyses.
Both male and female preteen initiators of each problem behavior were at greater risk for suicidal behaviors than non-initiators, even after controlling for covariates. More numerous concurrent problematic behaviors were correlated with greater likelihood of seriously considering or attempting suicide among both males and females. This pattern was more clearly observed in preteen than in teen initiators although the former and latter were engaged in the same frequency of problem behavior.
Early initiation of alcohol drinking, cigarette smoking, and sexual intercourse, particularly among preteens, represented an important predictor of later suicidal ideation and suicide attempts in both genders. Thus, early preventive intervention programs should be developed and may reduce the potential risks for subsequent suicidal behaviors.
本研究旨在探讨早期出现问题行为（饮酒、吸烟和性行为）与自杀行为（自杀意念和自杀未遂）之间的关联，并探讨这些问题行为同时发生对韩国青少年男女自杀行为的影响。
数据来自 2006 年韩国青少年风险行为调查，这是一项针对 7 至 12 年级中学生和高中生的全国代表性样本（男生 32417 名，女生 31467 名）。进行了双变量和多变量逻辑分析。分析中包括了一些重要的协变量，如年龄、家庭生活结构、家庭经济状况、学业成绩、当前饮酒、当前吸烟、当前使用丁烷气或胶水、感知体重、不健康的体重控制行为、主观睡眠评估和抑郁情绪。
无论是男性还是女性，每种问题行为的早期行为者都比非行为者更容易出现自杀行为，即使在控制了协变量之后也是如此。更多同时存在的问题行为与男女两性更有可能认真考虑或企图自杀相关。虽然前者和后者的行为频率相同，但在青少年前的行为者中，这种模式更为明显。
青少年早期开始饮酒、吸烟和性行为，特别是在青少年前，是两性后来出现自杀意念和自杀未遂的一个重要预测因素。因此，应该制定早期预防干预计划，这可能会降低随后出现自杀行为的潜在风险。
