Exposure to bioaerosols, respiratory health and lung-specific proteins: a prospective study in garbage and wastewater workers: Table 1

Abstract

OBJECTIVES: To prospectively assess respiratory health in wastewater workers and garbage collectors over 5 years. METHODS: Exposure, respiratory symptoms and conditions, spirometry and lung-specific proteins were assessed yearly in a cohort of 304 controls, 247 wastewater workers and 52 garbage collectors. Results were analysed with random coefficient models and linear regression taking into account several potential confounders. RESULTS: Symptoms, spirometry and lung-specific proteins were not affected by occupational exposure. CONCLUSIONS: In this population no effects of occupational exposure to bioaerosols were found, probably because of good working conditions.
