背景资料。在美国，吸烟是主要的可预防的死亡原因，而且生命中越早开始吸烟，患病的风险就越大。自1991年以来，美国青少年的吸烟率一直在上升。尽管电视烟草广告被禁止，但电视上吸烟的现象仍然很普遍。为了确定看电视次数越多的年轻人是否表现出更高的吸烟率。我们利用全国青少年和儿童纵向调查队列，纵向研究了1990-1992年间开始吸烟的10至15岁青少年中看电视的关联。电视收视率是根据青少年和家长的平均报告得出的。我们使用多元Logistic回归，考虑了抽样权重，并控制了种族、母亲教育、智商和工作、家庭结构、儿童数量、家庭贫困、儿童性别和儿童能力倾向测试分数。在这些年轻人中，吸烟的比例从1990年的4.8%上升到1992年的12.3%。控制基线特征，每天看电视5个小时或以上的年轻人开始吸烟的可能性是每天看4到5个小时的年轻人的5.99倍(95%可信区间：1.39-25.71)，是每天看电视4到5个小时的年轻人的5.24倍
Background. Smoking is the leading preventable cause of death in the United States, and the risk of disease increases the earlier in life smoking begins. The prevalence of smoking among US adolescents has increased since 1991. Despite bans on television tobacco advertising, smoking on television remains widespread.Objective. To determine whether youth with greater exposure to television viewing exhibit higher rates of smoking initiation.Methods. We used the National Longitudinal Survey of Youth, Child Cohort to examine longitudinally the association of television viewing in 1990 among youth ages 10 to 15 years with smoking initiation from 1990-1992. Television viewing was based on the average of youth and parent reports. We used multiple logistic regression, taking into account sampling weights, and controlled for ethnicity; maternal education, IQ, and work; household structure; number of children; household poverty; child gender; and child aptitude test scores.Results. Among these youth, smoking increased from 4.8% in 1990 to 12.3% in 1992. Controlling for baseline characteristics, youth who watched 5 or more hours of TV per day were 5.99 times more likely to initiate smoking behaviors (95% confidence interval: 1.39-25.71) than those youth who watched 4 to 5 hours per day were 5.24 times more likely to initiate smoking than youth who watched
