More Caffeine Could Benefit Women's Hearing
(HealthDay News) — Higher caffeine intake is tied to a lower risk of tinnitus in women, according to a study published in the August issue of The American Journal of Medicine.
Jordan T. Glicksman, MD, MPH, from the University of Western Ontario in London, Canada, and colleagues evaluated data from 65,085 women (mean age, 36.3 years) participating in the Nurses' Health Study II without tinnitus at baseline in 1991. Participants completed lifestyle and medical history questionnaires every two years and food frequency questionnaires every four years. Tinnitus status was obtained in 2009.
The researchers found that mean caffeine intake was 242.3mg/day. There were 5,289 incident cases of tinnitus reported over 18 years of follow-up. Caffeine intake and the incidence of tinnitus had a significant inverse association. The multivariable adjusted hazard ratios were 0.85 for those who consumed 450–599mg/day and 0.79 for those who consumed ≥600mg/day, compared to women with intake <150mg/day (equivalent to one 8-ounce cup of coffee).
"In this prospective study, higher caffeine intake was associated with a lower risk of incident tinnitus in women," the authors write.
