Objective
We sought to depict the topical, geospatial, and temporal diffusion of the 2015 NAMS position statement on the non-hormonal management of menopause-associated vasomotor symptoms released 09/21/15 and its associated press release from 09/23/15.
Methods
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 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 (09/12/815-09/22/15 vs. 09/23/15-10/03/15) and conducted a burst analysis to identify changes in Tweets from before to after.
Results
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=.649). Release of the statement coincided with bursts in the menopause conversation on Twitter.
Conclusions
The findings of this study may be useful for directing the development and dissemination of future NAMS position statements and/or press releases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
