摘　　要：目的了解新冠疫情发生前后公众对戒烟相关信息的网络关注度及变化趋势。方法在百度指数大数据分析平台,人工提取关键词“吸烟危害”“戒烟”“二手烟”和“电子烟”疫情发生前(2016年1月1日—2019年12月31日)和疫情发生后(2020年1月1日—2020年12月31日)的月度搜索指数数据。采用单因素方差分析比较有关数据显示期间各关键词间的年度搜索指数差异,采用线性回归模型分析疫情发生前搜索指数的年度间线性变化趋势,采用单样本均值t检验分析疫情发生后搜索指数与疫情前均值的差异。结果2016—2020年“电子烟”的年度搜索指数最高(约146.5万),其次是“吸烟危害”(约88.4万)和“戒烟”(约78.0万),“二手烟”最低(约17.1万)。疫情发生前(2016—2019年)各关键词的搜索指数累计增长量为正,但年度变化线性趋势不显著(P>0.05);疫情期间(2020年),“吸烟危害”的搜索指数较疫情前平均水平显著下降(约79.4万比90.7万,P=0.011),“戒烟”(约59.1万比82.7万,P=0.172)和“二手烟”(约16.4万比17.2万,P=0.257)亦呈现下降趋势,但“电子烟”逆势上涨,超过疫情前水平(约182.5万比137.5万,P=0.010)。结论新冠疫情发生后多数戒烟相关信息的网络关注度下降,但“电子烟”的网络关注度骤增,亟需加强对电子烟的监管及对科学戒烟方法的有效宣传。Objective To explore the hotspots of the public concerns about quitting smoking before and during the coronavirus disease 2019(COVID-19)pandemic.Methods The monthly search index data of four key words,“the harm of smoking”,“quitting smoking”,“passive smoking”and“electronic cigarette”before the COVID-19(from January,2016 to December,2019)and during the COVID-19(from January,2020 to December,2020)pandemic were manually collected from the Baidu Index platform.The one-way ANOVA was used to compare the differences among annual search indexes of four keywords.The linear regression model was used to test the annual linear trend of search index of each keyword before the COVID-19,and the one-sample t-test was used to analyze the differences of the search indexes during the COVID-19 and the means before the COVID-19.Results During 2016—2020,the annual average search index of“electronic cigarette”was the highest(1.465 million),followed by“the harm of smoking”(0.884 million)and“quitting smoking”(0.780 million),while“passive smoking”was the lowest(0.171 million).Before the COVID-19(2016—2019),the search index of each keyword had positive cumulative growth,but there was no significant linear trend of annual change(P>0.05).During the COVID-19 period(2020),the search index of“the harm of smoking”decreased significantly(0.794 million vs 0.907 million,P=0.011),and“quitting smoking”(0.591 million vs 0.827 million,P=0.172)and“passive smoking”(0.164 million vs 0.172 million,P=0.257)showed a downward trend,while the search index of“electronic cigarettes”bucked the trend and increased significantly(1.825 million vs 1.375 million,P=0.010).Conclusions The public′s online attention to“electronic cigarette”increases dramatically during COVID-19 along with other information about quitting smoking decreases.There are urgent needs for strengthening regulation and monitoring of electronic cigarettes and carrying out more effective publicity of scientific methods to help quit smoking.
