Increasingly, people smoke cigarettes outdoors and avoid exposing bystanders to harm. People may not have the same motivation to vape outdoors since e-cigarettes, unlike cigarettes, do not create side stream emissions and exhaled aerosol contains fewer toxicants than secondhand smoke. This study aims to estimate the prevalence and correlates of vaping and smoking indoors among adults in England.
Data came from the Health Survey for England 2019, a cross-sectional household survey. Adults who vape or smoke (N = 1530) were asked whether they had vaped or smoked indoors inside the home, car, or other places within the past 7 days. Logistic regression was used to estimate prevalence and key correlates of indoor use, including age, sex, presence of adults/children in home, housing tenure, and nicotine dependence.
People who exclusively vaped were much more likely to use their product indoors than those who exclusively smoked (87.0% vs. 52.0%; odds ratio [OR] = 6.16, 95% confidence interval [CI] = 4.09 to 9.28). Similarly, people who dual used had higher odds of vaping than smoking indoors (62.1% vs. 44.3%; OR = 3.76, 95% CI = 2.06 to 6.84). The preference for vaping over smoking indoors was found across different locations, including at home and in cars. Those who were older, highly dependent on nicotine, and lived alone were most prone to use any product indoors. While housing tenure was not strongly associated with vaping indoors, those living in social housing were much more likely to smoke indoors than homeowners.
Adults in England are much more likely to vape than smoke indoors. Age, nicotine dependence, and living alone are strongly associated with both behaviors.
Our results show that people have a strong preference for vaping over smoking indoors, including in the home. Given the high prevalence of vaping indoors, policy makers, landlords, and businesses must weigh up the ethics, benefits, and harms of extending smoke-free laws to include e-cigarettes.
越来越多的人在户外吸烟，并避免让旁观者受到伤害。与香烟不同，电子烟不会产生侧流排放物，呼出的气溶胶所含的有毒物质也少于二手烟，因此人们可能没有在户外吸电子烟的相同动机。本研究旨在估计英格兰成年人在室内吸电子烟和吸烟的流行率和相关因素。
数据来自 2019 年英格兰健康调查，这是一项横断面家庭调查。被调查者包括吸电子烟或吸烟的成年人（N=1530），询问他们在过去 7 天内是否在家中、汽车内或其他地方吸电子烟或吸烟。使用逻辑回归来估计室内使用的流行率和主要相关因素，包括年龄、性别、家中是否有成年人/儿童、住房所有权和尼古丁依赖。
只吸电子烟的人比只吸香烟的人更有可能在室内使用他们的产品（87.0%对 52.0%；优势比[OR]=6.16，95%置信区间[CI]=4.09 至 9.28）。同样，双重使用者在室内吸电子烟的可能性也高于吸烟（62.1%对 44.3%；OR=3.76，95%CI=2.06 至 6.84）。在不同地点，包括在家中和汽车内，都发现了室内吸电子烟而不是吸烟的偏好。年龄较大、尼古丁依赖性较高和独居的人最有可能在室内使用任何产品。虽然住房所有权与在室内吸电子烟没有很强的关联，但居住在社会住房中的人比房主更有可能在室内吸烟。
英格兰的成年人在室内吸电子烟的可能性远高于吸烟。年龄、尼古丁依赖和独居与这两种行为都有很强的关联。
我们的研究结果表明，人们在室内更倾向于吸电子烟而不是吸烟，包括在家中。鉴于在室内吸电子烟的高流行率，政策制定者、房东和企业必须权衡将无烟法律扩大到包括电子烟的伦理、好处和危害。
