China has more than 300 million current smokers. There is a controversy over smokers' risk of COVID-19 infection. Smoking is a risk factor for COVID-19 disease progression, and the outbreak of COVID-19 may change people's smoking behaviors. This study assessed people's attitudes towards 'smoking and COVID-19' and changes of smoking behaviors before and after the outbreak of COVID-19.
A cross-sectional web survey of 11009 adults in China was conducted between 7 May and 3 August 2020. Attitudes towards 'smoking and COVID-19' were compared among non-smokers (n=8837), ex-smokers (n=399) and current smokers (n=1773), and changes in smoking behaviors before and after the outbreak of COVID-19 were assessed among current smokers.
Fewer current smokers (26.2%) agreed with the statement that 'Current smokers are more likely than ex-smokers or non-smokers to contract COVID-19' compared with non-smokers (53%) or ex-smokers (41.4%); fewer current smokers (55.9%) agreed with the statement 'If contracted, current smokers are more likely than ex-smokers or non-smokers to risk disease progression' compared with non-smokers (75.5%) or ex-smokers (68.7%). There were no changes in cigarettes smoked per day (mean ± SD: 13.3 ± 9.55 vs 13.4 ± 9.69, p=0.414), percentage of daily smokers (70.8% vs 71.1%, p=0.882) and percentage of smokers with motivation to quit (intend to quit within the next 6 months, 9.4% vs 10.9%, p=0.148) before and after the outbreak of COVID-19.
The survey found that fewer current smokers agreed that smoking is a risk-factor for COVID-19 compared with non-smokers or ex-smokers. Among current smokers, there were no changes in their cigarette consumption and motivation to quit before and after the outbreak of COVID-19. More efforts are needed to educate smokers about the health risks of smoking, as well as efforts to promote their motivation to quit.
中国目前有超过3亿烟民。吸烟者感染新型冠状病毒肺炎（COVID-19）的风险存在争议。吸烟是COVID-19疾病进展的一个风险因素，且COVID-19疫情可能会改变人们的吸烟行为。本研究评估了人们对“吸烟与COVID-19”的态度以及COVID-19疫情爆发前后吸烟行为的变化。
于2020年5月7日至8月3日对中国11009名成年人进行了一项横断面网络调查。比较了非吸烟者（n = 8837）、既往吸烟者（n = 399）和当前吸烟者（n = 1773）对“吸烟与COVID-19”的态度，并评估了当前吸烟者在COVID-19疫情爆发前后吸烟行为的变化。
与非吸烟者（53%）或既往吸烟者（41.4%）相比，更少的当前吸烟者（26.2%）认同“当前吸烟者比既往吸烟者或非吸烟者更易感染COVID-19”这一说法；与非吸烟者（75.5%）或既往吸烟者（68.7%）相比，更少的当前吸烟者（55.9%）认同“如果感染，当前吸烟者比既往吸烟者或非吸烟者更易出现疾病进展风险”这一说法。COVID-19疫情爆发前后，每日吸烟量（均值±标准差：13.3±9.55对13.4±9.69，p = 0.414）、每日吸烟者比例（70.8%对71.1%，p = 0.882）以及有戒烟意愿的吸烟者比例（打算在未来6个月内戒烟，9.4%对10.9%，p = 0.148）均无变化。
该调查发现，与非吸烟者或既往吸烟者相比，更少的当前吸烟者认同吸烟是COVID-19的一个风险因素。在当前吸烟者中，COVID-19疫情爆发前后他们的吸烟量和戒烟意愿均无变化。需要做出更多努力来让吸烟者了解吸烟对健康的风险，同时努力提高他们的戒烟意愿。
