Cataracts in Dunedin Program participants: an evaluation of risk factors

A geriatric health screening program in Dunedin, Florida, was used to evaluate risk factors leading to development of cataracts. A total of 2,787 participants completed the fourth yearly visit to the program. At the time of the fourth visit, 49.3% of women (mean age 75.1 years) and 38.2% of men (mean age 75.4 years) reported the presence of cataracts. Age was found to be the most significant risk factor in cataract development (P less than .0001). Both men and women with cataracts had significantly lower serum cholesterol concentrations than subjects without cataracts. After adjusting for age and sex, diazepam (P less than .03), furosemide (P less than .04), isosorbide (P less than .003), and ibuprofen (P less than .03) were found to be positively associated with cataracts; triamterene (P less than .05) had a negative association, indicating a protective relationship. Aspirin was not shown to have a protective effect on reported cataracts.
