Lung function and respiratory symptoms related to changes in smoking habits in asbestos-exposed subjects.
The purpose of this study was to examine respiratory symptoms and lung function (forced vital capacity epsilonFVCzêta and forced expiratory volume in 1 second epsilonFEV#B1zêta) as related to changes in smoking habits in subjects previously exposed to asbestos.
The study was linked to a smoke-ending program among asbestos-exposed males.
Subjects were recruited from a population-based survey, and 231 smokers met for the baseline consultation.
The baseline prevalences of cough, chronic cough, and dyspnea among smokers were 68.0%, 44.6%, and 42.4%, respectively.
Both smoke-ending (n=10) and tobacco reduction (n=52) during the 2-year follow-up resulted in remission of cough and chronic cough, whereas dyspnea was unaffected.
When the 2-year measurements of FVC and FEV#B1 were adjusted for the respective baseline measurements, FEV#B1 tended to improve in subjects who had quit during the study, relative to the continuing smokers.
It was concluded that both smoke-ending and reduction of tobacco consumption resulted in reduction of cough and chronic cough, but not of dyspnea.
The study further suggests a possible positive effect of smoking cessation on FEV#B1, but not merely by reduction of tobacco consumption.
