Analyzing Mediterranean diet on Twitter: a 11-year analysis of tweets from the major US media outlets. (Preprint)
BACKGROUND Background: Media outlets influence social attitudes toward health habits. Analysis of tweets has become a tool for health research and dissemination of public health information. OBJECTIVE Objective: The objective of this study was to investigate the distribution of tweets about Mediterranean diet (MedDiet) and the interest generated among Twitter users. METHODS Methods: We investigated tweets posted between January 2009 and December 2019 by 25 major US media outlets about MedDiet and its components as well as the retweets and likes generated. In addition, we measured the sentiment analysis of these tweets and their dissemination. RESULTS Results: In total, 1,608 tweets, 123,363 likes and 48,946 retweets about MedDiet or its components were analyzed. Dairy (usually negatively weighted in MedDiet scores) accounted for 723 tweets (45.0%), followed by nuts 317 (19.7%). MedDiet, as an overall dietary pattern, generated only 157 (9.8%) of the total tweets, while olive oil generated the least number of tweets (31 tweets or 1.9%). Twitter users’ response was quantitatively related to the number of tweets posted by these US media outlets, except for tweets on olive oil and MedDiet as a whole: none of the MedDiet components analyzed was more likely to be liked or retweeted than the MedDiet itself. Between 2009 and 2019, there was progressive increase in the number of tweets and retweets on MedDiet and its components. CONCLUSIONS Conclusions: The US media outlets analyzed showed reduced interest in MedDiet as a whole, while Twitter users showed greater interest in the overall dietary pattern than in its particular components.
