Evaluation of chronic respiratory effects in the potato processing industry : indications of a healthy worker effect ?
To investigate the occurrence of chronic respiratory effects of exposure to organic dust in the potato processing industry.
Methods-Self reported chronic respiratory symptoms and spirometric lung function were assessed in a cross sectional study among 135 potato processing workers.
A comprehensive study of current exposure to dust, endotoxin, and potato antigens had been performed previously.
Workers were grouped into low and high exposure categories for each of the three exposure indices.
Relations between exposure concentrations and respiratory health variables were investigated either by calculating prevalence rate ratios or by performing linear regression analyses.
Atopy was assessed by measuring total immunoglobulin E (IgE) and specific IgE to five common aeroallergens in serum samples of workers.
Evident relations between current exposure indices and respiratory health in the entire group were not found.
Workers employed <=5 years showed a twofold higher prevalence of respiratory symptoms, lower lung function, and higher endotoxin exposure than workers employed for>5 years.
Also, atopy was more prevalent in workers employed <=5 years.
After stratification for duration of employment, negative effects of endotoxin on lung function among workers employed <=5 years were suggested. (...)
