Thematic characteristics and emotional tendencies of tobacco health information in Weibo
Objective To understand the thematic characteristics of tobacco information released by microblog us-ers,and to explore the communication effects of various types of tobacco information for providing theoretical references to ef-ficient dissemination of tobacco control.Methods Python software was used to crawl tobacco-related information posted by Weibo users,and UCINET software was used for data analysis and covariance matrix analysis.Results A total of 6385 to-bacco information was obtained after crawling and screening.Among them,the keywords of tobacco information were charac-terized by high heterogeneity and wide coverage,and the keyword frequency of"smoking"was the most highest.The tobacco information keywords of positive emotions(68.71％)were more than those of negative emotions(6.98％),and the fre-quencies of"smoking"and"second-hand smoking"were higher.Conclusion The network ecology of tobacco information in the micro-blog platform is good,and the content related to tobacco is relatively small,but it has strong temptation and concealment.Relevant departments should continue to pay attention to the tobacco epidemic vocabulary and strengthen the publicity of tobacco hazards and tobacco control laws,so as to guard against the spread of negative emotional tobacco infor-mation.
