导言：在黑人经历的健康差距中，烟草的使用是相当大一部分原因。除了它的生理影响，吸烟一直被证明与青少年的自杀有关。本研究的目的是描述在全国具有代表性的黑人高中生中特定的烟草使用行为模式与自杀行为之间的关系。方法：收集完成2007年青少年危险行为调查的黑人青少年(N=2931)的回答。潜在类别分析被用来识别基于两个领域的类型：(A)一生和最近吸烟和(B)自杀。此外，还调查了吸烟类成员和自杀类成员之间的关系，以及年龄和性别对类成员的直接影响。结果：相当大比例的黑人青年报告了吸烟和自杀行为。四类模型对烟草使用行为(不吸烟者、前吸烟者、轻度吸烟者和经常吸烟者)的数据提供了最好的总体匹配；三类模型对自杀(不是自杀、轻度自杀、自杀)的数据提供了最好的总体匹配。吸烟状况与自杀类别成员身份有关，与非自杀倾向相比，更强烈的吸烟模式与识别为轻度自杀和被归类为自杀倾向的概率增加有关。结论：本研究结果表明，任何当前吸烟状态都将自杀的可能性增加至少5倍，并提供了针对这一特定部分的黑人青少年吸烟者的动机。
Introduction: Tobacco use is responsible for a considerable portion of the health disparities experienced by Blacks. In addition to its physiological effects, tobacco use has consistently been shown to be associated with suicidality among adolescents. The purpose of the present study is to describe the association between specific patterns of tobacco use behavior and those of suicidality among a nationally representative sample of Black high school students.Methods: Responses from Black adolescents (N = 2,931) who completed the 2007 Youth Risk Behavior Surveillance Survey were included. Latent class analysis was utilized to identify typologies based on two domains: (a) lifetime and recent tobacco use and (b) suicidality. The association between tobacco use class membership and suicidality class membership as well as the direct effects of age and gender on class membership was also investigated.Results: A significant proportion of Black youth reported smoking and suicidal behaviors. A 4-class model provided the best overall fit to the data for tobacco use behavior (nonsmokers, former smokers, light current smokers, and frequent current smokers); a 3-class model provided the best overall fit to the data for suicidality (not suicidal, mild suicidality, suicidal). Smoking status was associated with suicidality class membership, with more intense patterns of smoking related to increased probability of identification with both mild suicidality and being classified as suicidal compared with not suicidal.Conclusions: The results of this study indicate that any current smoking status increases the likelihood of suicidality at least 5-fold and provides incentive to target this specific portion of the population of Black adolescent smokers.
