Secondhand smoke exposure in children is changing as a result of new public policy and electronic nicotine products (e-cigarettes). We examined factors related to self-imposed indoor household tobacco restrictions, with emphasis on children in the household and associations with combustible and noncombustible product use.
A cross-sectional survey of urban and rural Ohio adult tobacco users classified participants as exclusive combustible users, smokeless tobacco (SLT) users, e-cigarette users, or dual users. They were further stratified according to combustible or noncombustible product use and the presence of indoor tobacco use restrictions. Multiple logistic regression determined factors associated with indoor tobacco restrictions.
A total of 1210 tobacco users participated, including 25.7% with children living in the home. Half allowed combustible and two thirds allowed noncombustible tobacco use indoors. Urban location (odds ratio [OR] = 1.58), younger age (OR = 0.88 per 5 year), male sex (OR = 1.40), college education (OR = 1.40), household income of more than $15,000 (OR = 1.78), and being married (OR = 2.43) were associated with a higher likelihood of banning combustible products indoors. SLT (OR = 8.12) and e-cigarette (OR = 5.85) users were more likely to have indoor bans compared to combustible users. Children in the household (OR = 1.89), older age (OR = 1.12 per 5 years), and nonwhite race (OR = 1.68) were associated with a higher likelihood of banning noncombustible products indoors. Combustible (OR = 4.54) and e-cigarette (OR = 3.04) users were more likely than SLT users to have indoor bans.
Indoor restrictions on tobacco use remain infrequent in homes with children and are associated with user type and socioeconomic factors. Public policy should target modifiable risk factors for in-home secondhand smoke exposure.
由于新的公共政策和电子尼古丁产品（电子烟）的出现，儿童接触二手烟的情况正在发生变化。我们研究了与自我实施的室内家庭烟草限制相关的因素，重点是家庭中的儿童以及与可燃和不可燃产品使用的关联。
对俄亥俄州城乡成年烟草使用者进行横断面调查，将参与者分为仅可燃烟草使用者、无烟烟草（SLT）使用者、电子烟使用者或双重使用者。根据可燃或不可燃产品使用情况以及室内烟草使用限制情况对他们进行进一步分层。多因素逻辑回归确定与室内烟草限制相关的因素。
共有 1210 名烟草使用者参与了研究，其中 25.7%的参与者家中有儿童。一半人允许在室内使用可燃烟草，三分之二的人允许在室内使用非可燃烟草。居住在城市地区（优势比 [OR] = 1.58）、年龄较小（每增加 5 岁，OR = 0.88）、男性（OR = 1.40）、大学教育（OR = 1.40）、家庭收入超过 15000 美元（OR = 1.78）和已婚（OR = 2.43）与更有可能禁止在室内使用可燃产品相关。与可燃烟草使用者相比，SLT（OR = 8.12）和电子烟（OR = 5.85）使用者更有可能在室内禁烟。家中有儿童（OR = 1.89）、年龄较大（每增加 5 岁，OR = 1.12）和非白种人（OR = 1.68）与更有可能禁止在室内使用非可燃产品相关。与 SLT 使用者相比，可燃烟草（OR = 4.54）和电子烟（OR = 3.04）使用者更有可能在室内禁烟。
在有儿童的家庭中，室内限制吸烟的情况仍然很少见，并且与使用者类型和社会经济因素有关。公共政策应针对家庭中二手烟暴露的可改变风险因素。
