Title Combined effect of grain farming and smoking on lung function and the prevalence of chronic bronchitis
Bibliographic information June 1991, Vol.20, No.2, p.416-423. 36 ref.
Abstract The combined effect of grain farming and smoking on lung function and the prevalence of chronic bronchitis was examined in 1633 residents of Saskatchewan (Canada). Multiple multivariate analysis indicated that in women grain farming and smoking had a significant synergistic effect on ventilatory capacity. However, such combined effects were not statistically significant in men. Female non-smoking grain farmers had a similar prevalence of chronic bronchitis to non-smoking female non-farmers (2.0% and 2.1%, respectively). In women with a positive smoking history, however, the prevalence was 13.2% and 5.9%, respectively. The prevalence of chronic bronchitis increased more rapidly with increasing cigarette consumption in female grain farmers than in female non-farmers. In contrast, the effect of grain farming on the prevalence of chronic bronchitis was similar in men with and without a positive smoking history. The data suggest a positive interactive effect of grain farming exposure and smoking on lung function and the prevalence of chronic bronchitis in women.
