The news media are an important source of dietary information. Understanding news content, particularly the portrayal of risks and benefits of certain foods, is relevant for effective public health communication. Fish consumption may reduce risk for CVD and aid neonatal development, but recent work shows public confusion about the benefits of fish, challenged by the evidence of mercury and other contaminants in fish. We present an analysis of the messages about fish in US news media over 15 years, identifying trends in coverage and highlighting implications of current messaging.
We conducted a descriptive text analysis and coded for manifest content: locality of focus, story frame, reference to studies, inclusion of government guidelines and portrayal of uncertainty. We identified chronological patterns and analysed the data for statistically significant relationships between media source and content.
News stories were selected from five daily newspapers and five television networks (1993-2007).
We analysed 310 health-related news stories on fish.
Risk messages outweighed benefit messages four to one, and health benefits only became prominent after 2002. No difference existed in coverage topic by news source. Fish consumption has increasingly become a national issue.
With the bulk of messages about fish consumption focused on risk, the benefits may be lost to consumers. This gap creates a need for public health to work with news media to more effectively communicate benefits and risks around fish consumption and health and to consider options for communicating tailored information where it can be more readily utilised.
新闻媒体是饮食信息的重要来源。了解新闻内容,尤其是某些食品的风险和益处的描述,对于有效的公共卫生交流至关重要。鱼类消费可能降低 CVD 风险并有助于新生儿发育,但最近的研究表明,公众对鱼类益处存在困惑,这受到鱼类中汞和其他污染物证据的挑战。我们对 15 年来美国新闻媒体中关于鱼类的信息进行了分析,确定了报道趋势,并强调了当前信息传递的影响。
我们进行了描述性文本分析,并对明显内容进行了编码:焦点位置、故事框架、对研究的提及、政府指南的纳入以及不确定性的描述。我们确定了时间模式,并分析了媒体来源和内容之间存在统计学显著关系的数据。
从五家日报和五家电视网络(1993-2007 年)中选择了 310 篇与鱼类有关的健康新闻报道。
我们分析了 310 篇关于鱼类的健康相关新闻报道。
风险信息是益处信息的四倍,并且健康益处仅在 2002 年后才变得突出。新闻来源对报道主题没有区别。鱼类消费越来越成为全国性问题。
由于大部分关于鱼类消费的信息都集中在风险上,消费者可能会忽略其益处。这种差距使得公共卫生部门需要与新闻媒体合作,更有效地传达鱼类消费与健康的益处和风险,并考虑在更易于利用的地方传递量身定制信息的选择。
