An important movement in reducing youth smoking is to restrict the supply of cigarettes to youth by raising the minimum age of sales to 21, termed Tobacco 21. This study examined attitudes toward Tobacco 21 among youth and their correlations with tobacco use.
Data from the 2015 National Youth Tobacco Survey ( = 17 092, the typical age of 11-18 years) were analyzed to examine the prevalence of support toward Tobacco 21 among youth. This study further assessed whether attitudes toward Tobacco 21 were associated with (1) intention to initiate cigarette smoking among never-smoking youth ( = 16 449); and (2) intention to quit tobacco use among current tobacco users ( = 2914).
Approximately 63.9% of respondents reported supporting Tobacco 21. Support for Tobacco 21 was higher among middle school students (versus high school students), girls (versus boys), and noncurrent users of cigarettes or electronic cigarettes (versus current users). Youth support attitudes were significantly associated with perceptions of tobacco's danger and tobacco use by household members. Never smokers who supported Tobacco 21 had lower odds of intention to initiate cigarette use (adjusted odds ratio = 0.2, < .0001). Current tobacco users who supported Tobacco 21 had higher odds of intention to quit tobacco use in the next 12 months (adjusted odds ratio = 2.6, < .0001).
Tobacco 21 is supported by the majority of youth nationwide and youth attitudes were correlated with smoking behaviors. Education programs about the harm of smoking and nicotine addiction at the early stages of life may help increase support of this policy among young tobacco users.
减少青少年吸烟的一个重要举措是通过将销售年龄提高到 21 岁来限制向青少年供应香烟,这被称为烟草 21 岁。本研究调查了青少年对烟草 21 岁的态度及其与吸烟行为的相关性。
分析了 2015 年全国青少年烟草调查的数据(n=17092,典型年龄为 11-18 岁),以调查青少年对烟草 21 岁的支持率。本研究还评估了对烟草 21 岁的态度是否与以下因素相关:(1)从未吸烟的青少年中开始吸烟的意图(n=16449);(2)当前烟草使用者戒烟的意图(n=2914)。
约 63.9%的受访者表示支持烟草 21 岁。中学学生(相对于高中学生)、女生(相对于男生)和非当前使用香烟或电子烟的青少年(相对于当前使用者)对烟草 21 岁的支持度更高。青少年的支持态度与对烟草危险的认知以及家庭成员的吸烟或使用电子烟的行为显著相关。支持烟草 21 岁的从未吸烟者开始吸烟的意图较低(调整后的优势比=0.2,<0.0001)。支持烟草 21 岁的当前烟草使用者在未来 12 个月内戒烟的意图更高(调整后的优势比=2.6,<0.0001)。
全国大多数青少年都支持烟草 21 岁,青少年的态度与吸烟行为相关。在生命早期阶段开展有关吸烟危害和尼古丁成瘾的教育计划,可能有助于增加年轻烟草使用者对这项政策的支持。
