Title Prevalence and risk factors for chronic bronchitis and farmer's lung in French dairy farmers
Bibliographic information Oct. 1993, Vol.50, No.10, p.941-944. 15 ref.
Abstract The prevalence of chronic bronchitis and of clinical farmer's lung was studied in 30 districts of the French Doubs département in relation to individual (age, sex, smoking habits) and geographical (altitude) factors. 5,703 dairy farmers exclusively (response rate 83%) participated in the study by answering a medical questionnaire. Prevalences of chronic bronchitis and clinical farmer's lung were 9.3% and 1.4% respectively. A logistic regression model was used to evaluate risk factors for chronic bronchitis and clinical farmer's lung. A risk of chronic bronchitis was associated with the male sex (p<10-4), age (p<10-4), smoker category (p<10-4), and altitude (p<10-4). A risk of clinical farmer's lung was associated with non-smokers (p<0.05), and linearly with altitude (p<10-4). There was also a strong positive relation between chronic bronchitis and clinical farmer's lung (odds ratio 19.5 (95% CI: 12.1-31.4)) after adjustment for confounding variables. The main finding of this study was the highly significant increase of prevalence of the diseases in relation to altitude.
