To assess the prevalence of ownership of cigarette promotional items (CPIs) by rural northern New England students and to examine the association between CPI ownership and smoking behavior.
Voluntary, self-administered survey of 1265 sixth- through 12th-grade students representing 79% to 95% of all students attending 5 rural New Hampshire and Vermont public schools in October 1996. We examined the association between ownership of a CPI and smoking behavior through regression models and conducted a sensitivity analysis on the findings.
Adjusted odds of being a smoker (lifetime use of > or = 100 cigarettes) and, among never smokers and experimental smokers, adjusted cumulative odds of having higher levels of smoking uptake given CPI ownership.
One third of students owned a CPI. Prevalence of ownership did not vary by grade or sex, but was higher among poor-to-average school performers (45.0% vs 21.0% for excellent school performers, P < .001) and children whose friends and family members smoked (43.4% vs 13.8% for students with no family members or friends smoking, P < .001). Cigarette promotional items included articles of clothing (T-shirts, hats, backpacks, and jackets), smoking paraphernalia (lighters and ashtrays), camping gear, and electronics. More than half of CPIs (58.2%) bore the Marlboro logo, and almost one third (31.7%) bore the Camel logo. These items were obtained directly from catalogs or vendors 22.4% of the time. Whereas only 4.5% of students reported bringing a CPI to school with them the day of the survey, 44.5% reported seeing such an item at school the day of the survey. After controlling for confounding factors, such as having friends who smoke, students who owned CPIs were 4.1 times more likely to be smokers than those who did not own CPIs (95% confidence interval [CI], 3.1-5.5). Never and experimental smokers (n = 1008) who owned CPIs were more likely to be in a higher category on the smoking uptake index in grades 6 (cumulative odds ratio [OR = 5.7, 95% CI, 1.9-16.8), 7 (OR = 1.8, 95% CI, 0.9-3.7), 8 (OR = 2.3, 95% CI, 1.1-4.8), and 9 (OR = 2.1, 95% CI, 1.1-3.9), periods when children are most vulnerable to initiating cigarette use. A sensitivity analysis indicated that an unmeasured confounder of CPI ownership and smoking was unlikely to alter our conclusions.
Cigarette promotional items are owned by one third of students in these rural northern New England schools. These items are highly visible in the public school setting, and their ownership is strongly associated with initiation and maintenance of smoking behavior. These data lend support to a ban on CPIs to be included in US Food and Drug Administration regulations to prevent tobacco use among US youth.
评估新英格兰北部农村地区学生拥有香烟促销物品(CPI)的比例,并研究拥有CPI与吸烟行为之间的关联。
1996年10月,对新罕布什尔州和佛蒙特州5所农村公立学校的1265名6至12年级学生进行了自愿的自我管理调查,这些学生占所有学生的79%至95%。我们通过回归模型研究了拥有CPI与吸烟行为之间的关联,并对研究结果进行了敏感性分析。
成为吸烟者(终生使用≥100支香烟)的校正比值比,以及在从不吸烟者和尝试吸烟者中,考虑拥有CPI情况下吸烟量增加的校正累积比值比。
三分之一的学生拥有CPI。拥有率在不同年级和性别之间没有差异,但在学业成绩为中等到较差的学生中更高(学业成绩优秀的学生为21.0%,而学业成绩为中等到较差的学生为45.0%,P<0.001),在朋友和家庭成员吸烟的孩子中也更高(没有家庭成员或朋友吸烟的学生为13.8%,而有家庭成员或朋友吸烟的学生为43.4%,P<0.001)。香烟促销物品包括衣物(T恤、帽子、背包和夹克)、烟具(打火机和烟灰缸)、露营装备和电子产品。超过一半的CPI(58.2%)带有万宝路标志,近三分之一(31.7%)带有骆驼标志。这些物品有22.4%是直接从商品目录或供应商处获得的。虽然只有4.5%的学生报告在调查当天携带CPI上学,但44.5%的学生报告在调查当天在学校看到过此类物品。在控制了诸如朋友吸烟等混杂因素后,拥有CPI的学生成为吸烟者的可能性是未拥有者的4.1倍(95%置信区间[CI],3.1 - 5.5)。拥有CPI的从不吸烟者和尝试吸烟者(n = 1008)在6年级(累积比值比[OR = 5.7,95% CI,1.9 - 16.8])、7年级(OR = 1.8,95% CI,0.9 - 3.7)、8年级(OR = 2.3,95% CI,1.1 - 4.8)和9年级(OR = 2.1,95% CI,1.1 - 3.9)的吸烟量增加指数上更有可能处于较高类别,而这些时期是儿童最容易开始吸烟的时期。敏感性分析表明,一个未测量的CPI拥有与吸烟的混杂因素不太可能改变我们的结论。
在这些新英格兰北部农村学校中,三分之一的学生拥有香烟促销物品。这些物品在公立学校环境中随处可见,其拥有与吸烟行为的开始和维持密切相关。这些数据支持在美国食品药品监督管理局的法规中禁止香烟促销物品,以防止美国青少年吸烟。
