||Occupation and the risk of hearing impairment - Results from the Nord-Tr°ndelag study on hearing loss
||May 2010, Vol.36, No.3, p.250-257. 25 ref.
||Audiometry and a questionnaire concerning exposure were administered to a population sample of 49,948 adults in Norway. Information on occupation, education and income was obtained from population census registers. Occupation had marked effects on hearing loss. Occupation explained 2-3% of the variance in hearing loss among men aged 45 years or more in addition to the hearing loss due to age (10-19%). Occupation explained one percent or less of hearing loss among women of all ages and young men. Controlling for self-reported occupational noise exposure reduced the occupational effect by 20-40% in men aged 45 years or more. Controlling for leisure-time noise, ear infections and head injuries did not change the effect of occupation, which was slightly reduced after controlling for education and income. The most elevated hearing thresholds in men were observed among wood workers, miners, linemen and cable jointers, construction carpenters and workers, seafarers and workshop mechanics.
