This study aims to compare the trends of tobacco prevalence and secondhand smoke exposure in Rizhao, China, before and after the lockdown, and to analyze the changes in residents' awareness of smoking-related diseases.
Two cross-sectional surveys on tobacco prevalence and secondhand smoke exposure were conducted in Rizhao, China, in 2022 and 2024. The chi-square test was used to determine whether there were significant differences.
A total of 1872 valid questionnaires were collected from the two surveys. The results showed that the current smoking rate declined significantly from 32.53 to 25.84% ( = 10.08, = 0.002), with daily smoking rate also slightly decreased from 20.44 to 19.33% ( = 0.36, = 0.551). Paradoxically, the passive smoking rate among nonsmokers surged from 32.08 to 48.39% ( = 35.53, < 0.01), while residents' awareness of smoking-related diseases declined.
Our study reveals a paradoxical situation in Rizhao: declining active smoking contrasts sharply with escalating secondhand smoke exposure, along with decreasing public awareness of smoking-related diseases. These trends suggest that conventional tobacco control measures have been effective in curbing active smoking, while they are insufficient to address the new behavioral patterns emerging from the prolonged indoor confinement and changing work-life arrangements during the pandemic. Effective tobacco control campaigns and targeted interventions for key populations are urgently needed.
本研究旨在比较中国日照市封锁前后烟草流行趋势和二手烟暴露情况，并分析居民对吸烟相关疾病认识的变化。
于2022年和2024年在中国日照市进行了两项关于烟草流行和二手烟暴露的横断面调查。采用卡方检验确定是否存在显著差异。
两项调查共收集到1872份有效问卷。结果显示，当前吸烟率从32.53%显著下降至25.84%（χ² = 10.08，P = 0.002），每日吸烟率也略有下降，从20.44%降至19.33%（χ² = 0.36，P = 0.551）。矛盾的是，非吸烟者的被动吸烟率从32.08%飙升至48.39%（χ² = 35.53，P < 0.01），而居民对吸烟相关疾病的认识却有所下降。
我们的研究揭示了日照市一种矛盾的情况：主动吸烟率下降与二手烟暴露增加形成鲜明对比，同时公众对吸烟相关疾病的认识也在下降。这些趋势表明，传统的烟草控制措施在抑制主动吸烟方面是有效的，但在应对疫情期间长期室内禁闭和工作生活安排变化所产生的新行为模式方面却不够充分。迫切需要开展有效的烟草控制运动并对重点人群进行有针对性的干预。
