Electronic cigarette (e-cigarette) use continues to rise among adolescents, but little is known regarding their risk perceptions of e-cigarette use. We aimed to describe the lifetime use and perceived risk of e-cigarette use in the context of other risk-taking behaviors among adolescents in North Carolina.
Data were derived from the 2015 North Carolina Youth Risk Behavior Survey, which was administered to 503 middle school and 444 high school students in the Chapel Hill-Carrboro public school district. Survey participants self-reported their sex; ethnicity; school grade; ever-use of cigarettes, e-cigarettes, alcohol, and other illicit substances; perceived risk of harm of these products; and perceived view of their parents' and friends' perceptions of these products. Logistic regression analyses were used to assess associations between student-reported characteristics, risk behaviors, perceived product risk, and ever-use of e-cigarettes.
This study found that 4.6% of middle school students and 37.2% of high school students reported ever-use of e-cigarettes. E-cigarette use increased and perception of e-cigarette risk decreased with advancing grade. Ever-use of e-cigarettes surpassed ever-use of combustible cigarettes at all grades; 49.4% of e-cigarette users had never smoked cigarettes. The perception that friends view e-cigarette use as "wrong" correlated negatively with e-cigarette use (adjusted odds ratio = 0.43; 95% confidence interval, 0.19-0.97).
Self-reported results from students in one school district have limited generalizability to larger groups.
E-cigarette use among adolescents in North Carolina correlates positively with perceived friends' views of e-cigarettes, and use correlates negatively with personal perception of the risk of e-cigarettes. Based on our survey results, education and public health intervention regarding e-cigarette use may be best targeted at youth prior to their transition to high school.
青少年中电子烟的使用持续增加，但对于他们对使用电子烟的风险认知了解甚少。我们旨在描述北卡罗来纳州青少年在其他冒险行为背景下的电子烟终生使用情况及感知风险。
数据来自2015年北卡罗来纳州青少年风险行为调查，该调查对教堂山-卡伯勒公立学区的503名中学生和444名高中生进行。调查参与者自行报告他们的性别、种族、年级、是否曾使用香烟、电子烟、酒精及其他非法物质、对这些产品危害的感知风险，以及对父母和朋友对这些产品看法的感知。逻辑回归分析用于评估学生报告的特征、风险行为、感知产品风险与电子烟曾经使用之间的关联。
本研究发现，4.6%的中学生和37.2%的高中生报告曾使用电子烟。随着年级升高，电子烟使用增加而对电子烟风险的感知降低。在所有年级，电子烟的曾经使用都超过了可燃香烟的曾经使用；49.4%的电子烟使用者从未吸过香烟。认为朋友将电子烟使用视为“错误”的看法与电子烟使用呈负相关（调整优势比 = 0.43；95%置信区间，0.19 - 0.97）。
来自一个学区学生的自我报告结果对更大群体的普遍适用性有限。
北卡罗来纳州青少年中电子烟的使用与朋友对电子烟的看法呈正相关，且与个人对电子烟风险的感知呈负相关。基于我们的调查结果，关于电子烟使用的教育和公共卫生干预可能最好针对即将升入高中的青少年。
