The purpose of this study was to examine the relationship between adolescents' favorite movie stars and their smoking status, controlling for variables associated with smoking initiation.
The 1996 California Tobacco Survey questioned 6,252 adolescents about their favorite stars, smoking history, exposure to smokers, rebelliousness, knowledge and attitudes regarding smoking, and cigarette advertising and promotion. The top 10 favorite stars were tested for differential preference between ever and never smokers, defined as those who had never puffed on a cigarette. Never smokers were categorized as susceptible or nonsusceptible to smoking.
Favorite stars differed significantly among adolescent ever and never smokers. A majority of favorite stars of ever smokers smoked on and off screen compared to favorite stars of never smokers. In multivariate analyses, adolescent never smokers who preferred favorite stars of adolescent ever smokers were significantly more likely to be susceptible to smoking (OR = 1.35; 95% CI 1.12, 1.62), even after adjustment for known predictors of adolescent smoking and demographic variables. This effect was only slightly weaker than that of exposure to friends and family who smoke (OR = 1.45; 95% CI 1.13, 1.85).
This study provides preliminary evidence that stars who smoke on and off screen may encourage youth to smoke.
本研究旨在探讨青少年最喜欢的电影明星与其吸烟状况之间的关系，并控制与开始吸烟相关的变量。
1996年加利福尼亚烟草调查询问了6252名青少年关于他们最喜欢的明星、吸烟史、接触吸烟者的情况、叛逆性、对吸烟的知识和态度以及香烟广告和促销活动。对排名前十的最喜欢的明星进行了 ever吸烟者（定义为从未吸过烟的人）和从不吸烟者之间的差异偏好测试。从不吸烟者被分为易受吸烟影响或不易受吸烟影响两类。
青少年ever吸烟者和从不吸烟者最喜欢的明星有显著差异。与从不吸烟者最喜欢的明星相比，ever吸烟者最喜欢的明星中大多数在银幕内外都吸烟。在多变量分析中，即使在对青少年吸烟的已知预测因素和人口统计学变量进行调整后，更喜欢青少年ever吸烟者最喜欢的明星的青少年从不吸烟者更容易受到吸烟影响（OR = 1.35；95% CI 1.12, 1.62）。这种影响仅略弱于接触吸烟的朋友和家人（OR = 1.45；% CI 1.13, 1.85）。
本研究提供了初步证据，表明在银幕内外吸烟的明星可能会鼓励年轻人吸烟。
