  1. Prevalence and predictors of work related respiratory symptoms in workers exposed to organic dusts.

    Article - En anglais

    Objectives-The aims of this study were to document the prevalence of work related upper and lower respiratory tract symptoms in workers exposed to organic dusts and to identify variables predictive of their occurrence.

    Methods-A cross sectional survey with an administered questionnaire (a previously validated adaptation of the Medical Research Council (MRC) respiratory questionnaire) was performed.

    Symptoms were classified as work related by their periodicity.

    Demographic data, smoking habits, and occupational histories were recorded.

    Personal exposures to dust and endotoxin were measured and individual subjects ascribed an exposure value specific to occupation, site and industry.

    Cox's regression techniques were used to identify variables predictive of work related upper and lower respiratory tract symptoms.

    Information was stored using Dbase 3 and analysed with SPSS.


    1032 Workers (93% of the target population) were studied in nine different industries.

    The highest prevalences of work related lower respiratory tract symptoms (38.1%), upper respiratory tract symptoms (45.2%), and chronic bronchitis (15.5%) were found among poultry handlers.

    White workers were significantly more likely to complain of upper and lower respiratory tract symptoms.

    An individual in the swine confinement industry had a symptom complex compatible with byssinosis. (...)
