Prevalence of asthma symptoms among bakery workers in Abidjan (Côte d'Ivoire)
Abstract
The objective of the present study was to determine the prevalence of occupational asthma symptoms among bakery workers. A cross-sectional study was done in the District of Abidjan from February to September 2019 among bakery workers. The study covered all workers aged 18 and over, employed and present in the bakery during interviews and lung tests. The socio-demographic and professional questionnaire of the American Thoracic Society was used, and the obtained qualitative and quantitative data obtained were analyzed with Stata 15.1 software. Out of the 599 workers included in our study, we had 405 bakers (67.6%, IC 95% [0.637–0.712]), 127 salespersons/cashiers (21.2%, IC 95% [0.181–0.247]), 38 cleaning persons (6.3%, IC 95% [0.046–0.086]) and 29 administrative staff (4.8%, IC 95% [0.034–0.069]). 85.8% (IC 95% [0.828–0.884]) of workers did not have the professional qualification in the bakery sector and 11.3% (IC 95% [0.090–0.142]) were illiterate. The prevalence of probable occupational asthma was 9.7%, 2.3%, 0.6% and 1.2%, respectively, among bakers, salespersons/cashiers, cleaning persons and administrative staff. Furthermore, logistic regression analysis revealed a relationship between probable occupational asthma and family history of asthma among the bakers. As a conclusion, the exposure of bakery workers to flour appeared to be one of the risk factors for probable occupational asthma and the work-related asthma. Also, bakers with a family history of asthma had high risk of developing probable occupational asthma.
