Airway Inflammatory Profile Among Cleaning Workers From Different Workplaces

Summary

There are consistent evidences through epidemiologic studies in different places, reinforced by occupational asthma records studies, that cleaning workers have a high risk in developing asthma. These risk determinants are not totally known. The air around the worker may have some higher and lower molecular weight with different concentration peaks from removed dust of the cleaning process and volatile substances from cleaning products. Cleaning activities may occur in different places. Although the relationship between rhinitis and asthma is already established, there are not many studies about occupational rhinitis-related work place. This study aimed to investigate airway inflammation and respiratory symptoms of cleaning workers from different workplaces.

Questionnaires

Clinical profile and respiratory symptoms employees' evaluation were performed using specific questionnaires (European Community Respiratory Health Survey for occupational diseases evaluation (ECRHS), (adapted by Ribeiro et al, 2007) and the International Study of Asthma and Allergies in Childhood (ISAAC) - Asthma module, previously translated and validated.
