This paper examines overall and gender- and racial/ethnic-specific relationships between exposure to state-sponsored anti-tobacco televised advertising and smoking-related outcomes among US middle and high school students using five years of cross-sectional nationally representative data.
Nationally representative 8th, 10th, and 12th grade student sample data for 1999-2003 were merged with commercial ratings data on mean potential audience exposure to network and cable television anti-tobacco advertising across the 74 largest US designated market areas, resulting in a final sample size for analysis of 122,340. Associations between state-sponsored anti-tobacco televised advertising exposure and youth smoking-related beliefs and behaviours were modelled while controlling for relevant individual and environmental factors as well as other televised tobacco-related advertising.
Higher potential for exposure to state anti-tobacco advertising within the previous four months was generally associated with decreasing odds of current smoking across groups. In addition, such exposure was related, to varying degrees, with decreased perceptions that most/all friends smoked, stronger five-year intentions not to smoke, and increased perceived harm of smoking. These relationships appeared possibly to be weaker for Asian students.
The results from these analyses indicate that state anti-tobacco advertising significantly relates to beneficial outcomes -- especially regarding current smoking behaviour -- among US youth as a whole.
本文利用五年具有全国代表性的横断面数据,研究美国初高中学生接触州政府资助的反烟草电视广告与吸烟相关结果之间的总体关系,以及按性别和种族/族裔划分的特定关系。
将1999 - 2003年全国代表性的八年级、十年级和十二年级学生样本数据与美国74个最大指定市场区域网络和有线电视反烟草广告的平均潜在受众接触量的商业评级数据合并,最终分析样本量为122,340。在控制相关个人和环境因素以及其他与烟草相关的电视广告的同时,对州政府资助的反烟草电视广告接触与青少年吸烟相关信念和行为之间的关联进行建模。
在过去四个月内接触州反烟草广告的可能性越高,通常与各群体当前吸烟几率的降低相关。此外,这种接触在不同程度上与以下情况相关:认为大多数/所有朋友吸烟的观念减少、五年内不吸烟的意愿增强以及对吸烟危害的认知增加。这些关系在亚洲学生中可能较弱。
这些分析结果表明,州反烟草广告与美国青少年整体的有益结果显著相关,尤其是在当前吸烟行为方面。
