BACKGROUND: @entity7446 ( @entity7446 ) is the leading occupational @entity1576 in the area of S  o Paulo Municipality. Understanding its characteristics can provide useful information for better interventions. METHODS: From a joint registry of @entity7446 from five outpatient public clinics for occupational @entity1576 , data on occupation, with job titles corrected by an expert evaluation, agents, exposure and symptom duration, and spirometry were analyzed by gender. Data on employment for S  o Paulo Municipality were used to calculate expected ratios for @entity1 / @entity1 in broad economical sectors. RESULTS: Three hundred and ninety four @entity7446 cases were reported with a ratio of @entity1 / @entity1 of 1.5. @entity1 had significantly shorter exposure duration (5.6 +/- 5.2 vs. 8.9 +/- 9.0 years, P = 0.0005), shorter symptoms duration (2.6 +/- 3.7 vs. 3.2 +/- 3.5 years, P = 0.1270), and higher prevalence of previous atopy (27.0 vs. 18.4%, P = 0.0485). The main occupations related to @entity7446 cases were cleaning activities, working in plastics manufacture and in chemical and pharmaceutical plants. @entity1 reported significantly more exposures to cleaning products, biologic agents, and textile fibers, whereas @entity1 reported more exposures to @entity10225 , metal dusts and fumes, oil mists, wood dusts and anhydrides. @entity1 presented an increased risk of @entity7446 in the service sector (odds ratio (OR) = 1.77, confidence interval (CI) = 1.61-1.96). CONCLUSIONS: Cleaning services was the main reported occupation and cleaning products the main reported agents. @entity1 had significantly shorter exposure duration possibly due to difference in exposures, previous atopy, and behavior. There was an excess of cases of @entity1 in the service sector.
