ABSTRACT

Cigarette use is one of the leading causes of death in the United States, with most smokers beginning cigarette use in adolescence. Despite not being of legal age to make tobacco purchases, adolescents are quite successful in their acquisition. The current study used latent variable mixture modeling to identify smoking typologies among adolescents and examine associations with various sources of cigarettes (i.e., stealing, obtaining from friends, obtaining from family members, purchasing), social influences (parental objection to smoking, smoking friends), and demographics. Participants were 195 high school students caught with tobacco in school who completed surveys questions about their cigarette use, and cigarette use of family and friends. Results identified three latent classes pertaining to smoking patterns: recent, heavy, frequent smokers (RHFS), low infrequent smokers (LIS), and recent moderate smokers (RMS). Students in the RHFS and RMS groups were more likely to obtain cigarettes by purchasing or borrowing from a friend, and reported more friends who smoke and lower parental objection compared to LIS members. RHFS members also were more likely to obtain cigarettes from family and be of White race compared to the other groups. These findings highlight the need for tailored prevention or intervention programs depending on risk profile.

摘要

在美国，吸烟是导致死亡的主要原因之一，大多数吸烟者在青春期开始吸烟。尽管尚未达到购买烟草的法定年龄，但青少年购买烟草还是相当成功的。目前的研究使用潜在变量混合模型来识别青少年的吸烟类型，并检查与各种卷烟来源（即偷、从朋友那里获取、从家人那里获取、购买）、社会影响（父母反对吸烟、吸烟的朋友）的关联，和人口统计。参与者是 195 名在学校吸烟的高中生，他们完成了有关他们吸烟以及家人和朋友吸烟的调查问题。结果确定了与吸烟模式有关的三个潜在类别：近期、重度、经常吸烟者 (RHFS)、不经常吸烟者 (LIS) 和近期中度吸烟者 (RMS)。与 LIS 成​​员相比，RHFS 和 RMS 组的学生更有可能通过购买或从朋友那里借来香烟，并且报告有更多的朋友吸烟且父母反对率较低。与其他组相比，RHFS 成员也更有可能从家人那里获得香烟并且是白人。这些发现强调需要根据风险状况量身定制预防或干预计划。与其他组相比，RHFS 成员也更有可能从家人那里获得香烟并且是白人。这些发现强调需要根据风险状况量身定制预防或干预计划。与其他组相比，RHFS 成员也更有可能从家人那里获得香烟并且是白人。这些发现强调需要根据风险状况量身定制预防或干预计划。
