To estimate the frequency of secondhand smoke exposure among patients with asthma.
A cross-sectional study of asthma patients and non-asthmatic controls using questionnaires to identify secondhand smoke exposure at home, school, work, and public places.
We studied 544 severe asthma patients, 452 mild/moderate asthma patients, and 454 non-asthmatic patients. Among severe patients, the mean age was 51.9 years, 444 (81.6%) were female, 74 (13.6%) were living with a smoker, 383 (71.9%) reported exposure in public spaces and, of the 242 (44.5%) who worked/ studied, 46 (19.1%) reported occupational exposure. Among those with mild/moderate asthma, the mean age was 36.8 years, 351 (77.7%) were female, 50 (11.1%) reported living with a smoker, 381 (84.9%) reported exposure in public settings and, of the 330 (73.0%) who worked/ studied, 58 (17.7%) reported occupational exposure. An association between secondhand smoke exposure and disease control was found among patients with mild/moderate asthma. Among those interviewed, 71% of severe asthma patients and 63% of mild/moderate asthma patients avoided certain places due to fear of secondhand smoke exposure.
Secondhand smoke exposure is a situation frequently reported by a significant proportion of asthma patients. Individuals with asthma are exposed to this agent, which can hamper disease control, exacerbate symptoms and pose unacceptable limitations to their right to come and go in public settings.
评估哮喘患者二手烟暴露的频率。
采用问卷调查对哮喘患者和非哮喘对照者进行横断面研究，以确定在家中、学校、工作场所和公共场所的二手烟暴露情况。
我们研究了544例重度哮喘患者、452例轻/中度哮喘患者和454例非哮喘患者。重度患者的平均年龄为51.9岁，444例（81.6%）为女性，74例（13.6%）与吸烟者同住，383例（71.9%）报告在公共场所接触二手烟，在242例（44.5%）工作/学习的患者中，46例（19.1%）报告有职业暴露。在轻/中度哮喘患者中，平均年龄为36.8岁，351例（77.7%）为女性，50例（11.1%）报告与吸烟者同住，381例（84.9%）报告在公共场所接触二手烟，在330例（73.0%）工作/学习的患者中，58例（17.7%）报告有职业暴露。在轻/中度哮喘患者中发现二手烟暴露与疾病控制之间存在关联。在接受访谈的患者中，71%的重度哮喘患者和63%的轻/中度哮喘患者因担心二手烟暴露而避免前往某些场所。
相当一部分哮喘患者经常报告有二手烟暴露情况。哮喘患者会接触到这种物质，它会妨碍疾病控制、加重症状，并对他们在公共场所的来去权利造成不可接受的限制。
