@entity1 @entity393 @entity1274 @entity9303
This study used epidemiologic methods to examine @entity393 in the elderly. The Framingham Heart Study Cohort was the reference population. The @entity1 were 935 @entity1 and 1358 @entity1 , aged 57 to 89 years. Using a conservative definition of @entity393 as threshold levels greater than 20 dB above audiometric zero for at least one frequency from 0.5 to 4 kHz, the prevalence was estimated to be 83%. The majority of cases displayed a @entity1274 . There were no statistically significant differences by sex at 1 kHz and below. @entity1 had significantly better hearing than @entity1 at 2 kHz and above. A multivariate model was constructed to determine which variables had a significant impact upon @entity393 . Under the model, age, sex, illness, family history of @entity393 , @entity9303 , and noise exposure were significant population risk factors. Age was by far the most critical risk factor.
