IntroductionHearing loss and tinnitus are common in most populations, although few data have addressed hearing-related health among tribal members and the need for public health interventions.MethodsThis cross-sectional study examined prevalence and risk factors for hearing loss and tinnitus among 217 adults in a Pacific Northwest tribe. Frequency measures were conducted for difficulty hearing certain sounds and hearing aid use. In 2006, risk factors were examined for two outcomes-hearing loss and tinnitus-with analysis conducted in the same year.ResultsAlthough self-reported hearing loss was more common in men (24%) than women (13%), a larger percentage of women compared with men reported difficulty hearing certain sounds. Only 8% of study participants reported hearing aid use. After age adjustment, significant noise exposure was associated with hearing loss (OR=8.30, 95% CI=1.84, 37.52). The overall prevalence of tinnitus was 33% (similar in men and women). After adjusting for age, the odds of tinnitus in individuals with more than four ear infections was 4.77 (95% CI=1.89, 12.02) times the odds in those who never had an ear infection. Tinnitus was also associated with significant noise exposure (OR=2.24, 95% CI=1.28, 6.73) even after age adjustment.ConclusionsIncreasing age and significant noise exposure were associated with hearing loss in this tribe. Tinnitus was associated with significant noise exposure and history of otitis media, even after age adjustment. Public health efforts are needed to improve hearing-related health in this tribe through messages about noise exposure and use of hearing protection.Copyright © 2016 American Journal of Preventive Medicine.
