Abstract
The paper reports the results of an indirect laryngoscopic investigation performed in the two-year period 1988-89 on 347 workers in two different primary aluminium production plants. A model is proposed for classification of the laryngeal state into 4 classes of increasing severity of clinical findings. An analysis was made of the statistical relationship between laryngeal class, occupational exposure, cigarette smoking, alcohol consumption, and age. A multivariate analysis of the data was performed using the logistic regression test. Smoking and age were shown to have a statistically significant influence (p < 0.0001 and p < 0.005 respectively) on the development of chronic laryngitis. No statistically significant difference was observed for alcohol consumption and in the comparison between workers and controls.
