To relate exposure to televised youth smoking prevention advertising to youths' smoking beliefs, intentions, and behaviors.
We obtained commercial television ratings data from 75 US media markets to determine the average youth exposure to tobacco company youth-targeted and parent-targeted smoking prevention advertising. We merged these data with nationally representative school-based survey data (n = 103,172) gathered from 1999 to 2002. Multivariate regression models controlled for individual, geographic, and tobacco policy factors, and other televised antitobacco advertising.
There was little relation between exposure to tobacco company-sponsored, youth-targeted advertising and youth smoking outcomes. Among youths in grades 10 and 12, during the 4 months leading up to survey administration, each additional viewing of a tobacco company parent-targeted advertisement was, on average, associated with lower perceived harm of smoking (odds ratio [OR]=0.93; confidence interval [CI]=0.88, 0.98), stronger approval of smoking (OR=1.11; CI=1.03,1.20), stronger intentions to smoke in the future (OR=1.12; CI=1.04,1.21), and greater likelihood of having smoked in the past 30 days (OR=1.12; CI=1.04,1.19).
Exposure to tobacco company youth-targeted smoking prevention advertising generally had no beneficial outcomes for youths. Exposure to tobacco company parent-targeted advertising may have harmful effects on youth, especially among youths in grades 10 and 12.
探讨接触电视播放的青少年吸烟预防广告与青少年吸烟观念、意图及行为之间的关系。
我们从美国75个媒体市场获取了商业电视收视率数据,以确定青少年接触烟草公司针对青少年及针对家长的吸烟预防广告的平均情况。我们将这些数据与1999年至2002年收集的具有全国代表性的校本调查数据(n = 103,172)进行合并。多变量回归模型对个体、地理和烟草政策因素以及其他电视反烟草广告进行了控制。
接触烟草公司赞助的针对青少年的广告与青少年吸烟结果之间几乎没有关联。在10年级和12年级的青少年中,在调查前的4个月里,平均每多看一次烟草公司针对家长的广告,与较低的吸烟危害感知(优势比[OR]=0.93;置信区间[CI]=0.88, 0.98)、对吸烟更强的认可(OR=1.11;CI=1.03,1.20)、未来吸烟更强的意图(OR=1.12;CI=1.04,1.21)以及在过去30天内吸烟的可能性更大(OR=1.12;CI=1.04,1.19)相关。
接触烟草公司针对青少年的吸烟预防广告总体上对青少年没有有益影响。接触烟草公司针对家长的广告可能对青少年有有害影响,尤其是在10年级和12年级的青少年中。
