BOHRF Original Authors' Main Conclusions

The original authors' main conclusions are taken from Abstract, Results and Discussion. They are decided upon by the authors of the BOHRF occupational asthma guidelines and form part of the guidelines.

Questionnaire information was collected and included occupational exposures and smoking habits. Odds ratios (OR) were calculated for exposure before asthma onset, stratified by sex and age-class. The highest risks for asthma were associated with exposure to grain dust (OR = 4.2) and flour dust (OR = 2.80). Among males, significantly increased risks were observed after exposure to flour dust, welding fumes, man-made mineral fibres, and solvents. Among females, increased risks for asthma were associated with exposures to paper dust and textile dust. In logistic regression models controlling for age, smoking, sex and interacting exposures, increased risks were seen for welding fumes (OR = 2.0), man-made mineral fibres (OR = 2.6) and solvents (OR = 2.2). The fraction of asthma attributed to occupational exposures after adjusting for sex, smoking and age was 11%.
