In the present study 108 full time workers employed in various sections of a railway workshop and exposed to smoke and irritant fumes, and 45 matched control subjects from local administrative staff were investigated to find prevalence of chronic bronchitis. In all 18 (16.7%) workers and 4 (8.9%) control subjects had clinical evidence of chronic bronchitis. Peak expiratory flow rate less than 300 L/min was observed in 54.6% workers and 2.2% control subjects. A significantly higher prevalence of chronic bronchitis was seen in workers. The advancing age, smoking and duration of exposure had significant influence on prevalence of chronic bronchitis.
在本研究中，对108名受雇于铁路车间各部门且接触烟雾和刺激性烟雾的全职工人，以及45名来自当地行政人员的匹配对照对象进行了调查，以确定慢性支气管炎的患病率。共有18名（16.7%）工人和4名（8.9%）对照对象有慢性支气管炎的临床证据。54.6%的工人和2.2%的对照对象呼气峰值流速低于300升/分钟。工人中慢性支气管炎的患病率明显更高。年龄增长、吸烟和接触时间对慢性支气管炎的患病率有显著影响。
