SENSORY IMPAIRMENT, FUNCTIONAL STATUS AND AGING

Project: Research project

Project Details

Description

An estimated twenty-eight million people in the United States are hearing
impaired. More than three million Americans are estimated to have a best-
corrected visual acuity of 20/40 or worse. The combination of increasing
prevalence of visual and hearing impairment with age and the rapid
increase in the proportion of Americans aged 65 and older will lead to a
steady increase in the number of sensory impaired individuals in this
country. Despite the growing importance of hearing impairment and visual
impairment as a public health problem there has been relatively little
research on the epidemiology of these conditions. This study will: 1)
estimate the prevalence of hearing impairment and visual impairment as
well as the prevalence of both sensory impairments among adult African-
Americans, Cuban-Americans, Mexican Americans, Puerto Ricans and Whites;
2) examine the influence of these conditions on the health and mental
well-being in these groups; and 3) examine the influence of these
impairments on change in functional status and risk of mortality. Data
for this project are derived from the Hispanic Health and Nutrition
Examination Survey (HHANES), the National Health and Nutrition Examination
Survey I (NHANES I), and the NHANES I Epidemiologic Follow-up Surveys
(1982-1984, 1986, 1987 and 1992), each of which were conducted by the
National Center for Health Statistics (NCHS). Data on sensory impairment
includes: ear examination, pure audiometry, speech audiometry,
ophthalmologic examination, visual acuity testing as well as self report
measures of visual and hearing impairment. Measures of functional status
include: activities of daily living, health care facility stays, well-
being,m depression and self-rated health. Analyses will be conducted
separately for males and females within the five racial/ethnic groups.
Because of the complex multi-stage sampling design used in the surveys,
analyses will be performed in three stages: 1) Ignoring both the sampling
weights and the design effect; 2) Incorporating only the sampling weights;
and 3) Incorporating both the sampling weights and the design effect.
This project will provide a comprehensive, integrated analysis of these
NCHS studies leading to significant advances in our understanding of the
epidemiology and influence of visual impairment, hearing impairment and
multiple sensory impairment on functional health status in adults.
