To determine whether changes in news media coverage of smoking and health issues are associated with changes in smoking behaviour in the USA.
Issue importance in the US news media is assessed by the number of articles published annually in major magazines indexed in The Reader's Guide to Periodical Literature. Annual incidence rates for cessation and initiation in the USA were computed from the large, representative National Health Interview Surveys (1965-1992). Patterns in cessation incidence were considered for ages 20-34 years and 35-50 years. Initiation incidence was examined for adolescents (14-17 years) and young adults (18-21 years) of both sexes.
From 1950 to the early 1980s, the annual incidence of cessation in the USA mirrored the pattern of news media coverage of smoking and health, particularly for middle aged smokers. Cessation rates in younger adults increased considerably when second hand smoke concerns started to increase in the US population. Incidence of initiation in young adults did not start to decline until the beginning of the public health campaign against smoking in the 1960s. Among adolescents, incidence rates did not start to decline until the 1970s, after the broadcast ban on cigarette advertising.
The level of coverage of smoking and health in the news media may play an important role in determining the rate of population smoking cessation, but not initiation. In countries where cessation has lagged, advocates should work to increase the newsworthiness of smoking and health issues.
确定美国新闻媒体对吸烟与健康问题报道的变化是否与吸烟行为的变化相关。
通过《读者期刊文献指南》索引的主要杂志每年发表的文章数量来评估美国新闻媒体对问题的重视程度。美国戒烟和开始吸烟的年发病率是根据具有代表性的大型国民健康访谈调查(1965 - 1992年)计算得出的。考虑了20 - 34岁和35 - 50岁人群的戒烟发病率模式。对青少年(14 - 17岁)和青年(18 - 21岁)男女的开始吸烟发病率进行了研究。
从1950年到20世纪80年代初,美国的年戒烟发病率反映了新闻媒体对吸烟与健康的报道模式,尤其是对中年吸烟者而言。当二手烟问题在美国人群中开始增加时,年轻成年人的戒烟率大幅上升。直到20世纪60年代针对吸烟的公共卫生运动开始,青年成年人的开始吸烟发病率才开始下降。在青少年中,直到20世纪70年代香烟广告广播禁令之后,发病率才开始下降。
新闻媒体对吸烟与健康的报道水平可能在决定人群戒烟率方面发挥重要作用,但对开始吸烟率没有影响。在戒烟进展滞后的国家,倡导者应努力提高吸烟与健康问题的新闻价值。
