Menopause. 2017 Oct;24(10):1154-1159. doi: 10.1097/GME.0000000000000891.
We sought to depict the topical, geospatial, and temporal diffusion of the 2015 North American Menopause Society position statement on the nonhormonal management of menopause-associated vasomotor symptoms released on September 21, 2015, and its associated press release from September 23, 2015.
Three data sources were used: online news articles, National Public Radio, and Twitter. For topical diffusion, we compared keywords and their frequencies among the position statement, press release, and online news articles. We also created a network figure depicting relationships across key content categories or nodes. For geospatial diffusion within the United States, we compared locations of the 109 National Public Radio (NPR) stations covering the statement to 775 NPR stations not covering the statement. For temporal diffusion, we normalized and segmented Twitter data into periods before and after the press release (September 12, 2015 to September 22, 2015 vs September 23, 2015 to October 3, 2015) and conducted a burst analysis to identify changes in tweets from before to after.
Topical information diffused across sources was similar with the exception of the more scientific terms "vasomotor symptoms" or "vms" versus the more colloquial term "hot flashes." Online news articles indicated media coverage of the statement was mainly concentrated in the United States. NPR station data showed similar proportions of stations airing the story across the four census regions (Northeast, Midwest, south, west; P = 0.649). Release of the statement coincided with bursts in the menopause conversation on Twitter.
The findings of this study may be useful for directing the development and dissemination of future North American Menopause Society position statements and/or press releases.
我们试图描绘2015年9月21日发布的北美更年期协会关于更年期相关血管舒缩症状非激素管理的立场声明及其2015年9月23日相关新闻稿在主题、地理空间和时间上的传播情况。
使用了三个数据源：在线新闻文章、美国国家公共电台和推特。对于主题传播，我们比较了立场声明、新闻稿和在线新闻文章中的关键词及其出现频率。我们还创建了一个网络图表，描绘关键内容类别或节点之间的关系。对于美国境内的地理空间传播，我们将报道该声明的109家美国国家公共电台的位置与未报道该声明的775家美国国家公共电台的位置进行了比较。对于时间传播，我们将推特数据进行归一化处理，并划分为新闻稿发布前和发布后的时间段（2015年9月12日至2015年9月22日与2015年9月23日至2015年10月3日），并进行了突发分析，以确定推文从发布前到发布后的变化。
除了更科学的术语“血管舒缩症状”或“VMS”与更通俗的术语“潮热”有所不同外，各来源间传播的主题信息相似。在线新闻文章表明，该声明的媒体报道主要集中在美国。美国国家公共电台的数据显示，四个普查区域（东北部、中西部、南部、西部）播出该报道的电台比例相似（P = 0.649）。该声明的发布与推特上更年期话题的激增相吻合。
本研究结果可能有助于指导未来北美更年期协会立场声明和/或新闻稿的制定和传播。
