To characterise how online media coverage of journal articles on cancer funded by the US government varies by cancer type and stage of the cancer control continuum and to compare the disease prevalence rates with the amount of funded research published for each cancer type and with the amount of media attention each receives.
A cross-sectional study.
The United States.
The subject of analysis was 11 436 journal articles on cancer funded by the US government published in 2016. These articles were identified via PubMed and characterised as receiving online media attention based on data provided by Altmetric.
16.8% (n=1925) of articles published on US government-funded research were covered in the media. Published journal articles addressed all common cancers. Frequency of journal articles differed substantially across the common cancers, with breast cancer (n=1284), lung cancer (n=630) and prostate cancer (n=586) being the subject of the most journal articles. Roughly one-fifth to one-fourth of journal articles within each cancer category received online media attention. Media mentions were disproportionate to actual burden of each cancer type (ie, incidence and mortality), with breast cancer articles receiving the most media mentions. Scientific articles also covered the stages of the cancer continuum to varying degrees. Across the 13 most common cancer types, 4.4% (n=206) of articles focused on prevention and control, 11.7% (n=550) on diagnosis and 10.7% (n=502) on therapy.
Findings revealed a mismatch between prevalent cancers and cancers highlighted in online media. Further, journal articles on cancer control and prevention received less media attention than other cancer continuum stages. Media mentions were not proportional to actual public cancer burden nor volume of scientific publications in each cancer category. Results highlight a need for continued research on the role of media, especially online media, in research dissemination.
描述美国政府资助的癌症相关期刊文章的在线媒体报道如何因癌症类型和癌症控制连续体的阶段而异，并将每种癌症类型的疾病流行率与资助研究的数量以及媒体对每种癌症类型的关注度进行比较。
横断面研究。
美国。
分析的主题是 2016 年发表的美国政府资助的 11436 篇癌症期刊文章。这些文章是通过 PubMed 确定的，并根据 Altmetric 提供的数据被归类为接受在线媒体关注。
在由美国政府资助的研究中，有 16.8%（n=1925）的文章被媒体报道。发表的期刊文章涵盖了所有常见癌症。常见癌症的期刊文章数量差异很大，乳腺癌（n=1284）、肺癌（n=630）和前列腺癌（n=586）是发表文章最多的癌症。每个癌症类别中大约有五分之一到四分之一的期刊文章受到在线媒体的关注。媒体报道与每种癌症类型的实际负担不成比例（即发病率和死亡率），乳腺癌文章获得了最多的媒体报道。科学文章也在不同程度上涵盖了癌症连续体的各个阶段。在 13 种最常见的癌症类型中，4.4%（n=206）的文章侧重于预防和控制，11.7%（n=550）的文章侧重于诊断，10.7%（n=502）的文章侧重于治疗。
研究结果显示，在线媒体报道的癌症类型与常见癌症类型之间存在不匹配。此外，癌症控制和预防方面的期刊文章比其他癌症连续体阶段受到的媒体关注更少。媒体报道与实际公众癌症负担或每个癌症类型的科学出版物数量不成比例。结果强调需要继续研究媒体，特别是在线媒体，在研究传播中的作用。
