Title Predictors of asthma and wheezing in adults - Grain farming, sex, and smoking
Bibliographic information Sep. 1993, Vol.148, No.3, p.667-670. 18 ref.
Abstract Predictors for asthma and wheeze were investigated in 1,634 subjects in the 20-65 age group from a Saskatchewan (Canada) town. Subjects were classified as asthmatic (n=62), wheezing (n=444), asymptomatic (n=908), or symptomatic (n=220). After excluding the symptomatic group, it was found that significant predictors for asthma were grain farming (odds ratio (OR)=1.9, 95% confidence interval (CI): 1.1-3.5; p=0.03) and sex (OR=1.9, CI: 1.1-3.2; p=0.03; males compared with females). Significant predictors for wheezing were smoking (former smoker: OR=1.8, CI: 1.3-2.5, p<0.001; current smoker: OR=5.0, CI: 3.8-6.7, p<0.001; in comparison to non-smoker) and grain farming (OR=1.7, CI: 1.3-2.4, p<0.001). Age, level of education, and physical activity at work were not significant predictors for asthma or wheezing. Grain farming was a significant predictor of asthma in men but not in women. Nevertheless, smoking and grain farming were significant predictors of wheezing in both sexes.
