RESUMO
This study described the San Diego Odor Identification Test (SDOIT) reliability and compared the SDOIT and the Brief Smell Identification Test (B-SIT). Ninety participants aged 50-70 years completed this 2-visit olfaction study. During visit 1, the SDOIT and B-SIT were administered according to standard protocols. Three weeks later, participants returned to retake the SDOIT. The SDOIT score was the total number of odorants correctly identified out of 8 odorants presented, and olfactory impairment was defined as correctly identifying less than 6 odorants. The B-SIT score was the total number of odorants correctly identified out of 12 odorants presented, and participants correctly identifying less than 9 odorants were categorized as abnormal. The SDOIT reliability was high (concordance correlation coefficient = 0.85, 95% confidence interval [CI] = 0.79-0.91). The same score was obtained on retest for 73% of participants, whereas 18% improved, and 9% declined. Test-retest agreement was 96% for the SDOIT; 4% improved from impaired at visit 1 to unimpaired at visit 2. Overall, SDOIT impairment classification and B-SIT abnormal classification agreed in 96% of participants (kappa = 0.81, 95% CI = 0.63-0.99). In conclusion, the SDOIT showed good test-retest reliability. Agreement for impaired/abnormal olfaction was demonstrated for the SDOIT and the B-SIT.

A population-based study to assess the use of hearing protection devices by older adults during noisy recreational activities was performed. The population-based Epidemiology of Hearing Loss Study was designed to measure the prevalence of hearing loss in adults residing in Beaver Dam, Wisconsin. The use of hearing protection devices during noisy recreational activities was assessed by performing three examinations over a period of 10 years (1993-1995, no. of participants (n)=3753, aged 48-92 years; 1998-2000, n=2800, aged 53-97 years; 2003-2005, n=2395, aged 58-100 years). The recreational activities included hunting, target shooting, woodworking/carpentry, metalworking, driving loud recreational vehicles, and performing yard work using either power tools or a chain saw. The prevalence of using hearing protection devices during any of these activities increased with time (9.5%, 15.0%, and 19.9% at baseline, 5 years, and 10 years, respectively). However, the use of hearing protection devices remained low for most activities. Those under the age of 65 were twice as likely to use hearing protection devices during noisy activities than were older adults. Men, those with a hearing handicap, and those with significant tinnitus were more likely to use hearing protection devices. Smokers and the less educated were less likely to use hearing protection devices. The results demonstrated that many adults expose themselves to potentially damaging recreational noise, leaving them at risk for hearing loss.

OBJECTIVE: To evaluate the association of NIDDM with hearing loss in a large population-based study. RESEARCH DESIGN AND METHODS: Data from population-based longitudinal studies of aging conducted in Beaver Dam, Wisconsin, were used in these analyses. Hearing thresholds were determined by pure-tone air- and bone-conduction audiometry performed by trained technicians following American Speech-Language-Hearing Association specifications. Hearing loss was defined as the pure-tone average of the frequencies 500, 1,000, 2,000, and 4,000 Hz greater than 25 decibels hearing level in the worse ear. Diabetes status was determined by self-report of physician-diagnosed diabetes or by elevated glucose or glycated hemoglobin levels at examination. RESULTS: Of 3,571 study participants, 344 were classified as having NIDDM. Subjects with NIDDM were more likely to have a hearing loss than were subjects without diabetes (59 vs. 44%). After results were adjusted for age, this difference was not statistically significant. After individuals with hearing loss patterns inconsistent with presbycusis were excluded, there was an association between NIDDM and hearing loss when controlling for potential confounders (odds ratio [OR] 1.41, 95% CI 1.05-1.88). There was no association between duration of diabetes or glycemic control and hearing loss. Individuals with NIDDM and nephropathy were more likely to have a hearing loss than were those with NIDDM but no nephropathy (OR 2.28, 95% CI 1.04-5.00). CONCLUSIONS: These data are suggestive of a weak association between NIDDM and hearing loss.

OBJECTIVE: To determine if quality of life differs between patients with choroidal melanoma treated with enucleation and those treated with radiation therapy. MATERIALS AND METHODS: Patients treated for choroidal melanoma at 5 Midwest centers were asked to participate. There were 65 participants treated with enucleation and 82 treated with radiation therapy. Quality of life was assessed using the Medical Outcome Study Short Form 36 and the National Eye Institute Visual Function Questionnaire and by the Time-Tradeoff interview method. RESULTS: The average length of follow-up was 4.9 years for the group treated with radiation therapy and 6.3 years for the group treated with enucleation (P = .05). After adjusting for age, sex, years of follow-up, and the number of chronic conditions, there were few differences in any of the quality-of-life measures by treatment status. Participants in the group treated with radiation therapy were more likely to have higher (better) scores on the Vitality and Mental Component subscales of the Medical Outcome Study Short Form 36 than participants treated with enucleation. There were no differences on the National Eye Institute Visual Function Questionnaire or the Time-Tradeoff measures of quality of life. CONCLUSION: Choice of treatment for choroidal melanoma does not seem to be associated with large differences in quality of life in long-term follow-up.

PURPOSE: Cataract and hearing loss are each common at older ages and together may influence the ability to function independently and affect the sense of well-being. For these reasons, we sought to estimate the risk factors for comorbidity of age-related cataract and hearing loss. METHODS: A cross-sectional evaluation of a population-based cohort of older adults was conducted in Beaver Dam, Wisconsin, for presence of age-related cataract and hearing loss. The study evaluation included taking standardized medical histories, measuring blood pressures, and obtaining blood specimens. Standardized photographs, which were graded according to well-defined protocols to assess the presence of nuclear, cortical or posterior subcapsular cataract, were taken. Audiometric testing was performed according to well-defined study protocols. RESULTS: Any type of cataract in combination with hearing loss in either ear was frequent, occurring in 27.8% of the population overall and increasing consistently with age. Nuclear and posterior subcapsular cataract in combination with hearing loss occurred more often in men. Lifestyle factors that were associated with at least one cataract-hearing loss end point in at least one sex were history of heavy drinking and smoking. CONCLUSIONS: In this community, older adults appear to be at high risk of cataract and hearing loss. Although risk is strongly associated with age, some elective exposures appear to influence risk. It is possible that modification of certain lifestyle habits may alter these risks.

Because people with diabetes may be at increased risk of glaucoma, we performed a pilot study using automated visual field testing for screening them. One hundred and seventy-six diabetic persons who had participated in the Wisconsin Epidemiologic Study of Diabetic Retinopathy were tested with the Armaly-Drance screening pattern on the Humphrey Visual Field Analyzer. Individuals with moderate diabetic retinopathy or worse tended to have lower sensitivity of the central visual field and missed more points than those with no or only mild retinopathy. People with a history of glaucoma had slightly less sensitivity and missed more points than controls. These preliminary findings suggest that although people with diabetes and glaucoma may more frequently have visual field defects than people with diabetes but no glaucoma, a larger study is needed. This pilot study shows that such a study would be feasible and should be designed to indicate the sensitivity, specificity, and cost-benefit ratio of a screening program so as to assess the utility of the screening visual field test for finding glaucoma amongst people with diabetes.

The purpose of this study was to investigate the association of noisy leisure activities with hearing loss. Participants (n=3571) were examined in a population-based study of age-related hearing loss conducted in Beaver Dam, Wisconsin. Hearing thresholds were determined by audiometry. Hearing loss was defined as the pure-tone average of the frequencies 500, 1,000, 2,000, and 4,000 Hz greater than 25 dB HL in either ear. Information regarding exposure to leisure-time noise was obtained by interview. After adjusting for potential confounders, individuals who engaged in leisure activities with average sound levels greater than 90 dBA were significantly more likely to have a hearing loss than participants who did not engage in noisy leisure activities (OR=1.11, 95 per cent CI=1.01-1.22). Individuals who engaged in woodworking were 30 per cent more likely to have a hearing loss than those who had never done woodworking. There was a 6 per cent increased risk of hearing loss for each 5-year period of participation. Health care professionals should consider counseling their patients who engage in noisy leisure activities about the risk of noise-induced hearing loss.
