评估在推特上发现的关于电子烟危害的错误信息对成年现役吸烟者的戒烟意愿、购买电子烟的意愿以及电子烟相对于普通香烟的相对危害感知的影响。
2019年11月在美国和英国的现役吸烟者中进行的一项在线随机对照实验。
从一个在线小组招募了2400名年龄≥18岁的成年现役吸烟者，他们不是当前的电子烟使用者。使用最少填充随机化函数以1:1:1:1的比例对参与者进行随机分组。
在以下四种情况之一中随机顺序查看4条推文：（1）电子烟与吸烟一样有害或更有害，（2）电子烟完全无害，（3）电子烟的危害不确定，以及（4）关于体育活动的推文作为对照条件。
自我报告的测试后的戒烟意愿、购买电子烟的意愿以及电子烟相对于吸烟的相对危害感知。
在美国和英国的参与者中，在控制了结果的基线测量值后，与对照相比，接触到电子烟与吸烟一样有害或更有害的推文与测试后购买电子烟的意愿降低（β = -0.339，95%置信区间 -0.487至 -0.191，p < 0.001）以及测试后对电子烟相对危害的感知增加（β = 0.341，95%置信区间0.273至0.410，p < 0.001）有关。在美国吸烟者中，接触到电子烟完全无害的推文与测试后购买电子烟的意愿增加（β = 0.229，95%置信区间0.002至0.456，p = 0.048）以及测试后对电子烟相对危害的感知降低（β = -0.154，95%置信区间 -0.258至 -0.050，p = 0.004）有关。
美国和英国的成年现役吸烟者在短暂接触到电子烟与吸烟一样有害或更有害的推文后，可能会被阻止考虑使用电子烟。相反，美国成年现役吸烟者在接触到电子烟完全无害的推文后，可能会被鼓励使用电子烟。这些发现表明，关于电子烟危害的错误信息可能会影响一些成年吸烟者考虑使用电子烟的决定。

To assess the effect of exposure to misinformation about e-cigarette harms found on Twitter on adult current smokers’ intention to quit smoking cigarettes, intention to purchase e-cigarettes and perceived relative harm of e-cigarettes compared with regular cigarettes. An online randomised controlled experiment conducted in November 2019 among USA and UK current smokers. 2400 adult current smokers aged ≥18 years who were not current e-cigarette users recruited from an online panel. Participants’ were randomised in a 1:1:1:1 ratio using a least-fill randomiser function. Viewing 4 tweets in random order within one of four conditions: (1) e-cigarettes are just as or more harmful than smoking, (2) e-cigarettes are completely harmless, (3) e-cigarette harms are uncertain, and (4) a control condition of tweets about physical activity. Self-reported post-test intention to quit smoking cigarettes, intention to purchase e-cigarettes, and perceived relative harm of e-cigarettes compared with smoking. Among US and UK participants, after controlling for baseline measures of the outcome, exposure to tweets that e-cigarettes are as or more harmful than smoking versus control was associated with lower post-test intention to purchase e-cigarettes (β=−0.339, 95% CI −0.487 to –0.191, p<0.001) and increased post-test perceived relative harm of e-cigarettes (β=0.341, 95% CI 0.273 to 0.410, p<0.001). Among US smokers, exposure to tweets that e-cigarettes are completely harmless was associated with higher post-test intention to purchase e-cigarettes (β=0.229, 95% CI 0.002 to 0.456, p=0.048) and lower post-test perceived relative harm of e-cigarettes (β=−0.154, 95% CI −0.258 to –0.050, p=0.004). US and UK adult current smokers may be deterred from considering using e-cigarettes after brief exposure to tweets that e-cigarettes were just as or more harmful than smoking. Conversely, US adult current smokers may be encouraged to use e-cigarettes after exposure to tweets that e-cigarettes are completely harmless. These findings suggest that misinformation about e-cigarette harms may influence some adult smokers’ decisions to consider using e-cigarettes. ISRCTN16082420.
