title: [Noise-induced hearing loss and its association with cumulative working time among urban bus workers].
abstract: Through regression analysis the relationship between noise-induced hearing loss and variables "total cumulative working time", "arterial blood pressure" and "age" was examined. The study was carried out among 278 bus drivers and ticket takers, users of an occupational health center in Campinas, São Paulo State (Brazil). The main results were a positive association between hearing loss and cumulative working time, as well as an interaction between this variable and the bus workers' age.
