Abstract Introduction Work-aggravated asthma (WAA) represents a significant proportion of asthma in the workplace. This entity is distinguished from work-related asthma (WRA) by a particular allergic background and a different sectoral distribution.The aim of our study was to compare the socio-professional, clinical and etiological characteristics of two groups including WRA and WAA. Methods Retrospective descriptive study of patients who consulted the occupational pathology and fitness for work department of the Charles Nicolle Hospital during the period from January 2016 to December 2022.Two groups were defined G1: WRA G2: WAA. Results We identified 140 cases of asthma patients of whom 59% were WAA and 41% WRA. The sex ratio (M/F) was (G1=0.62, G2=1.51, p=0.012). The mean age was (G1=44±8 years, G2=42±9 years, p=0.18). Personal atopy was found (G1=44%, G2=70%, p=0.002). WRA was present in the textile sector (G1=33%, G2=10%, p=10-3), chemical industry (G1=23%, G2=23%, p=0.15). WAA was present in the transport (16%) and service (14%) sectors. An association of occupational asthma with occupational rhinitis was found (p=0.06). The average professional seniority was higher in WRA without significance (G1= 17±9 years, G2= 14±10years, p=0.11). The main agents incriminated in G1 were textile and vegetal dusts (25%) and isocyanates (16%).The avoidance of exposure to allergenic agents was indicated (G1 = 79% vs G2 = 85%;p=10-3). Conclusion According to our study, WRA is more frequent in women and in the textile sector and can be associated with occupational rhinitis.It is essential to keep away people at risk.
