CONTEXT Older adults represent the fastest-growing segment of the US population, and prevalences of vision and hearing impairment have been extensively evaluated. However, despite the importance of sense of smell for nutrition and safety, the prevalence of olfactory impairment in older US adults has not been studied. OBJECTIVE To determine the prevalence(More)
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(More)
In animal models, inflammatory processes have been shown to have an important role in the development of kidney disease. In humans, however, the independent relation between markers of inflammation and the risk of chronic kidney disease (CKD) is not known. To clarify this, we examined the relationship of several inflammatory biomarker levels(More)
The objective of this study was to determine the prevalence of olfactory impairment and associated risk factors and the effects of olfactory impairment on dietary choices and quality of life. Odor identification was measured in 2838 participants aged 21-84 years (mean 49 years) in the Beaver Dam Offspring Study. The overall prevalence of olfactory(More)
Taste or gustatory function may play an important role in determining diet and nutritional status and therefore indirectly impact health. Yet there have been few attempts to study the spectrum of taste function and dysfunction in human populations. Epidemiologic studies are needed to understand the impact of taste function and dysfunction on public health,(More)
Few population-based data exist to assess the impact of tinnitus on quality of life. As part of the Epidemiology of Hearing Loss Study, self-reported data on tinnitus and quality of life were obtained by interview at the first follow-up examination (1998-2000; N = 2800; ages 53-97 years). The Medical Outcomes Study Short Form Health Survey (SF-36) was used(More)
OBJECTIVES Evidence suggests inflammation is associated with cognitive impairment, but previous epidemiological studies have reported conflicting results. DESIGN Prospective population-based cohort. SETTING Epidemiology of Hearing Loss Study participants. PARTICIPANTS Individuals without cognitive impairment in 1998-2000 (N = 2,422; 1,947 with(More)
STUDY OBJECTIVES To determine the prevalence of insomnia traits in a population and the effect of these traits on health-related quality of life. DESIGN The Epidemiology of Hearing Loss Study is a population-based study in Beaver Dam, Wisconsin. SETTING Participants were interviewed as part of the 5-year follow-up examination (1998-2000) of the(More)
OBJECTIVES To determine whether odor identification ability is associated with the 5-year incidence of cognitive impairment in a large population of older adults with normal cognition at baseline and whether olfactory impairment contributes to the prediction of cognitive decline. DESIGN Population-based longitudinal study. SETTING Beaver Dam, Wisconsin.(More)
BACKGROUND Carotid atherosclerosis has been suggested to be involved in cognitive decline. METHODS The Epidemiology of Hearing Loss Study is a longitudinal study of aging among Beaver Dam residents, WI. In 1998-2000, carotid intima-media thickness (IMT) and plaque were measured by ultrasound; cognitive function was measured by the Mini-Mental State(More)
