Smoking initiation places adolescents at risk for adult onset diseases, including heart disease, respiratory illness, and cancer. Adolescents that smoke have levels of 'perceived' tobacco addiction that are associated with several measures of nicotine dependence. Nonsmoking adolescents also report feeling addicted to tobacco even with minimal or no prior tobacco use, suggesting some vulnerability to tobacco use. The purpose of this study was to examine the association between perceived tobacco addiction and smoking susceptibility among adolescents with very minimal tobacco use. A cross-sectional analysis was conducted of data obtained from 5155 nonsmokers who completed the British Columbia Youth Survey of Smoking and Health II, a school-based survey conducted during 2004. Measures included demographics, tobacco use (ever puffed a cigarette), substance use (marijuana and alcohol), exposure to family members' smoking in the home, peers' tobacco use, depressive symptoms, perceived physical and mental addiction to tobacco, and smoking susceptibility. The adolescents who were most susceptible to smoking were female, younger and in a lower school grade; had ever puffed a cigarette, had used alcohol or marijuana; had family members or peers who smoked; had higher depression scores, and higher perceived physical and mental addiction to tobacco. In multivariate logistic regression analysis, perceived mental addiction but not perceived physical addiction to tobacco was significantly associated with smoking susceptibility. Understanding factors associated with smoking initiation, and ways to identify "at- risk" adolescents can enhance early intervention and prevention programs. Perceived mental addiction to tobacco appears to be an important indicator of smoking susceptibility.
吸烟使青少年面临成人期疾病的风险，包括心脏病、呼吸道疾病和癌症。吸烟的青少年对烟草的“感知”成瘾程度与尼古丁依赖的几个衡量标准相关。不吸烟的青少年即使有最小或没有吸烟史，也会报告对烟草有上瘾的感觉，这表明他们对烟草使用有一定的易感性。本研究旨在探讨青少年在极少量吸烟的情况下，感知烟草成瘾与吸烟易感性之间的关联。对 5155 名不吸烟者完成的不列颠哥伦比亚青少年吸烟与健康调查 II 的数据进行了横断面分析，该调查是在 2004 年在学校进行的。测量指标包括人口统计学数据、烟草使用情况（是否曾吸过香烟）、物质使用情况（大麻和酒精）、家庭中家庭成员吸烟的暴露情况、同伴的烟草使用情况、抑郁症状、对烟草的身体和心理成瘾的感知以及吸烟易感性。最容易吸烟的青少年是女性、年龄较小、年级较低；曾吸过香烟，使用过酒精或大麻；有家庭成员或同伴吸烟；抑郁得分较高，对烟草的身体和心理成瘾程度较高。在多变量逻辑回归分析中，对烟草的心理成瘾感知而不是身体成瘾感知与吸烟易感性显著相关。了解与吸烟起始相关的因素以及识别“高危”青少年的方法可以增强早期干预和预防计划。对烟草的心理成瘾感知似乎是吸烟易感性的一个重要指标。
