Material from an X-ray survey in a population of about 30,000 and symptomatic survey in a representative sample of 2,839 persons, 15 years or more in age, has been utilized to estimate the prevalence of ‘chronic bronchitis’. The prevalence as judged from the presence of symptoms only, appears to be between 3.9% and 5.6% in this population but only about half of these symptomatics had, in addition, radiological features associated with ‘chronic bronchitis’. The pattern regarding age and sex distribution in these two sub-groups is different. Long term surveillance of a large population is necessary to assess the significance of these differences, remove the shortcomings of the current definition and study the natural history of the disease in our country. The study corroborates association of ‘chronic bronchitis’ in males with smoking A study of the fuel used in the household has shown highly significant co-relation between ‘chronic bronchitis’ in females and use of cowdung cakes, wood and sawdust as fuel.
