358-363. An epidemiological survey to determine the prevalence of bronchitis in men employed at two of the National Coal Board's coking plants is described. Eight hundred and eighty-one men (91%) of the total working population were examined. A strong association was found between bronchitis prevalence and cigarette smoking (P < 0·001). In addition, men who smoked and who were exposed to high temperatures, dust, and fumes in the environment of the coke-ovens had more bronchitis than men who worked elsewhere in the cokeworks (P < 0·02). Both the presence of bronchitis and employment in the environment of the coke-ovens had significant and independent effects on ventilatory capacity. The combination of cigarette smoking and previous employment in a dusty industry also had a significant effect on ventilatory capacity. The investigation suggests that cigarette smoking, and the combination of smoking and pollution from the coke-ovens and previous occupation, appear to be important factors in the aetiology of bronchitis and reduced ventilatory capacity in men employed in the coke manufacturing industry.
358 - 363. 本文描述了一项流行病学调查,旨在确定在国家煤炭委员会的两家焦化厂工作的男性中支气管炎的患病率。对全体在职人员中的881名男性(占91%)进行了检查。发现支气管炎患病率与吸烟之间存在密切关联(P < 0.001)。此外,在焦炉环境中吸烟且暴露于高温、灰尘和烟雾的男性比在焦化厂其他地方工作的男性患支气管炎的人数更多(P < 0.02)。支气管炎的存在以及在焦炉环境中的工作对通气能力均有显著且独立的影响。吸烟与之前在粉尘行业工作的组合对通气能力也有显著影响。该调查表明,吸烟、吸烟与焦炉污染及先前职业的组合,似乎是焦化制造业男性支气管炎病因及通气能力下降的重要因素。
