||The textile industry sector occupies a prominent place in the economy of Benin. It exposes
workers to several occupational risks, including exposure to cotton dust. To assess the effect of
exposure to cotton dust on the health of workers, this study was initiated and conducted in a Beninese
cotton industry company. The objective of the study was to evaluate the respiratory disorders among
the textile workers exposed to cotton dust and the cross-sectional study involved 656 subjects exposed
to cotton dust and 113 non-exposed subjects. The methods used are mainly based on a survey using
a questionnaire of organic dust designed by the International Commission of Occupational Health
(ICOH); and on the measures of lung function parameters (FEV1 and FVC). The main results of the
different analyzes revealed that subjects exposed to cotton dust have more respiratory symptoms than
unexposed subjects (36.9% vs. 21.2%). The prevalence of chronic cough, expectorations, dyspnoea,
asthma and chronic bronchitis are 16.8%, 9.8%, 17.3%, 2.6%, and 5.9% respectively among the exposed
versus 2.6%, 0.8%, 16.8%, 0% and 0.8% among the unexposed subjects. The prevalence of byssinosis is
44.01%.The prevalence of symptoms is dependent on the sector of activity and the age of the subject.
These results should encourage medical interventions and technical prevention especially since the
textile industry occupies an important place in the Benin’s economy.
