Title Joint effects of smoking, noise exposure and age on hearing loss
Bibliographic information Jan. 2005, Vol.55, No.1, p.48-53. 32 ref.
Abstract This cross-sectional study was carried out to examine whether smoking, noise and age jointly affect hearing acuity. It involved 535 male workers of a metal processing factory. Pure-tone audiometric tests were used to assess hearing loss. and noise exposure assessment was based on a job-exposure matrix. Data on socio-demographic, life-style, occupational and health-related factors were collected by questionnaire. Results indicated that age and occupational noise exposures were separately and positively associated with hearing loss. For all the factors combined, the estimated effect on hearing loss was higher than the sum of the effects from each isolated variable. It is concluded that the synergistic effect of smoking, noise exposure and age on hearing loss is consistent with the biological interaction.
