Researchers conducted hearing thresholds measurement, ostoscopic evaluation, screening tympanogram, and a questionnaire on hearing-related medical history, noise exposure, and other risk factors. The results revealed that hearing loss is a very common problem among older adults of both sexes.

Antioxidant intake and risk of incident age-related nuclear cataracts in the Beaver Dam Eye Study

Article Abstract:

The relation of antioxidants and the incidence of nuclear cataracts was examined in a short-term study. Vitamins C and E, along with 5 carotenoids were assessed at baseline in 1988-1990 and at follow-up in 1993-1995. Lutein-zeaxanthin was the only carotenoid that appeared to be associated with nuclear cataract. Vitamins C and E were inversely associated with opacities in those who had risk factors for cataracts, but the study provided weak support for the associations.
