| Abstract |
This thesis investigates acute and chronic changes of ventilatory capacities and the prevalence of respiratory symptoms in 233 non-smoking Ethiopian factory workers exposed to cotton, tobacco and cement dusts. The prevalence of respiratory symptoms (chronic cough, chronic bronchitis and bronchial asthma) was higher in all dust-exposed groups than in non-exposed subjects. Significant reductions in lung function parameters (FVC, FEV1, MMFR, PEFR) over the workshift were recorded among cotton and tobacco workers. For cement workers, acute reductions were recorded only in FVC and PEFR. A substantial number of workers were found to have lower values of ventilatory capacities than their predicted values. |
