A survey for the prevalence of chronic bronchitis in an industrial population in North India is reported. The prevalence of chronic bronchitis is 12.5 percent in 473 subjects between the ages of 17 and 64 years. The prevalence rate of chronic bronchitis is comparable to that observed in areas of low community air pollution in Europe and North America. There is no age-related rise in the frequency of respiratory symptoms. The consumption of tobacco in these subjects is low and is comparable to tobacco consumption of light smokers. The prevalence of chronic bronchitis in smokers is five times the prevalence in non-smokers and is similar to the values reported for light smokers in other surveys. These observations suggest that cigarette smoking is associated with the development of chronic bronchitis, and the differences in the prevalence rate of chronic bronchitis between this survey and other surveys conducted in Europe and North America are mainly due to differences in smoking habits. Air pollution has a minor effect only and ethnic differences do not appear to play any part. Forced expired volume in one second shows a negative correlation with age. It is lower in asymptomatic smokers than in non-smokers and is lower in chronic bronchitis than in controls.
本文报告了一项针对印度北部工业人口慢性支气管炎患病率的调查。在473名年龄在17至64岁之间的受试者中，慢性支气管炎的患病率为12.5%。慢性支气管炎的患病率与在欧洲和北美的低社区空气污染地区观察到的患病率相当。呼吸道症状的频率没有随年龄增长而上升。这些受试者的烟草消费量较低，与轻度吸烟者的烟草消费量相当。吸烟者中慢性支气管炎的患病率是非吸烟者的五倍，与其他调查中报告的轻度吸烟者的值相似。这些观察结果表明，吸烟与慢性支气管炎的发生有关，本次调查与在欧洲和北美进行的其他调查中慢性支气管炎患病率的差异主要是由于吸烟习惯的不同。空气污染仅具有较小的影响，种族差异似乎不起任何作用。一秒用力呼气量与年龄呈负相关。无症状吸烟者的该指标低于非吸烟者，慢性支气管炎患者的该指标低于对照组。
