sodium-ethylxanthate and Respiratory-Tract-Diseases

Chronic non-specific respiratory disease was found by a survey at Chilliwack, B.C., to affect 29.3% of men and 18.0% of women between the ages of 25 and 74. The habit of current cigarette smoking was found to be the most important single factor associated with respiratory disease, and was found to be related to changes in simple measures of lung function. The authors were unable to confirm the existence of a threshold in lifetime cigarette smoking before respiratory disease occurred.Comparisons were made with a population previously studied at Berlin, New Hampshire, U.S.A., in 1961. At Berlin, where pollution by SO(2) and dust-fall had been thoroughly documented, the comparable prevalence rates for respiratory disease were 40.0% for men and 21.6% for women. When differences between the two populations as to age and number of cigarettes smoked daily were taken into account, the disease rates in these two communities were found to be quite similar. The Chilliwack sample did, however, have significantly higher values for the lung function tests.

In order to ascertain the prevalence of chronic respiratory disease in residents of a rural town and to determine the relative importance of tobacco smoking and air pollution, a survey was conducted of 726 persons living at Chilliwack, British Columbia, in May and June, 1963. Over 95% of a random sample of adults was interviewed and performed simple tests of respiratory function. The sample was selected from a commercial census. An analysis of the demographic characteristics of the sample indicated that the group, aged 25 to 74 years, was reasonably representative for detailed study of chronic respiratory disease.
