Résumé : | Context: Scotland prohibited smoking in confined public places on March 26, 2006. Objective: To investigate the association of smoke-free legislation with symptoms, pulmonary function, and markers of inflammation of bar workers. Design, Setting, and Participants: This prospective observational study was conducted in Tayside, Scotland from February-June 2006. One hundred five nonasthmatic and asthmatic nonsmoking bar workers were initially enrolled, of whom 77 completed the study per protocol. Main Outcome Measures: Respiratory and sensory symptoms, spirometry measurements, serum cotinine levels, peripheral inflammatory cell count, asthma quality-of-life scores, and exhaled nitric oxide levels were evaluated before and after introduction of the smoking ban. Results: For the per-protocol analysis, the percentage of bar workers with respiratory and sensory symptoms decreased from 79.2% (n = 61) before the smoke-free policy to 53.2% (n = 41) (total change, -26%; 95% confidence interval [CI], -13.8% to -38.1%; P<.001 and ci to p months afterward. forced expiratory volume in the first second increased from predicted then serum cotinine levels decreased ng total white blood cell neutrophil count was reduced cells at respectively. asthmatic bar workers also had less airway inflammation with a reduction exhaled nitric oxide parts per billion ppb month after ban change juniper quality-of-life scores points conclusions: smoke-free legislation associated significant early improvements symptoms spirometry measurements systemic of workers. improved quality life. s abstract> |
