BRANCO, Anadergh Barbosa de Abreu and ILDEFONSO, Simone de Andrade Goulart. Prevalence and duration of social security benefits allowed to workers with asthma in Brazil in 2008. J. bras. pneumol. [online]. 2012, vol.38, n.5, pp. 550-558. ISSN 1806-3713. http://dx.doi.org/10.1590/S1806-37132012000500003.
OBJECTIVE: To determine the prevalence and duration of social security benefits (SSBs) claims to registered workers with asthma in Brazil by the Brazilian National Institute of Social Security in 2008. METHODS: This was a retrospective, descriptive study, based on information obtained from the Brazilian Unified Benefit System database, on the number of SSB claims granted to registered workers with asthma in 2008. The reference population was the monthly mean number of workers registered in the Brazilian Social Registry Database in 2008. The variables studied were type of economic activity, gender, age, and type/duration of the SSB claim. The relationship between work and asthma was evaluated by the prevalence ratio (PR) between work-related and non-work-related SSB claims for asthma. RESULTS: In 2008, 2,483 SSB claims were granted for asthma, with a prevalence of 7.5 allowances per 100,000 registered workers. The prevalence was higher among females than among males (PR = 2.1 between the sexes). Workers > 40 years of age were 2.5 times more likely to be granted an SSB claim for asthma than were younger workers. The prevalence was highest among workers engaged in the following types of economic activity: sewage, wood and wood product manufacturing, and furniture manufacturing (78.8, 22.4, and 22.2 claims/100,000 registered workers, respectively). The median (interquartile range) duration of SSB claims for asthma was 49 (28-87) days. CONCLUSIONS: Asthma is a major cause of sick leave, and its etiology has a strong occupational component. This has a major impact on employers, employees, and the social security system. Being female, being > 40 years of age, and working in the areas of urban sanitation/sewage, wood and wood product manufacturing, and furniture manufacturing increase the chance of sick leave due to asthma.
