This study explores the relationship between cancer newspaper coverage and public knowledge about cancer prevention, confirming self-reported associations between news exposure and cancer prevention knowledge with descriptions of newspaper coverage of modifiable cancer risks. Content analyses (N = 954) revealed that newspapers pay relatively little attention to cancer prevention. However, there is greater newspaper attention to tobacco and diet than to exercise, sun, and alcohol. Survey analysis (the National Cancer Institute's Health Information National Trends Survey) revealed that after controlling for differences based on gender, race, age, income, and education, attention to health news was significantly associated with knowledge about cancer risks associated with food and smoking but not for knowledge about exercise, sun, or alcohol. These findings conform to the findings of the content analysis data and provide a validation of a self-reported measure of media exposure, as well as evidence suggesting a threshold below which news coverage may not generate public knowledge about cancer prevention.
本研究探讨了报纸对癌症的报道与公众癌症预防知识之间的关系，通过对可改变的癌症风险的报纸报道描述，证实了新闻曝光与癌症预防知识之间自我报告的关联。内容分析（N = 954）显示，报纸对癌症预防的关注相对较少。然而，报纸对烟草和饮食的关注比对运动、阳光和酒精的关注更多。调查分析（美国国家癌症研究所的健康信息全国趋势调查）显示，在控制了基于性别、种族、年龄、收入和教育的差异后，对健康新闻的关注与与食物和吸烟相关的癌症风险知识显著相关，但与运动、阳光或酒精的知识无关。这些发现与内容分析数据的结果一致，为媒体曝光的自我报告测量提供了验证，也为新闻报道可能无法产生公众癌症预防知识的阈值提供了证据。
