Oral disease and physical disability in community-dwelling older persons.
OBJECTIVE
The aim of this epidemiologic investigation was to determine whether poor oral health in older persons was associated with physical disability.


METHODS
The study was a cross-sectional survey involving in-home interviews and dental examinations of older persons.


METHODS
A random sample of 68 cities and towns was selected from the six New England states, with stratification according to population size.


METHODS
The study sample consisted of 1,156 community-dwelling (non-institutionalized) individuals aged 70 and over, randomly selected from the Medicare beneficiary lists for each city and town.


METHODS
Oral health was assessed by three dichotomous indices: edentulism (no teeth); current caries, including either coronal or root decay; and periodontal disease, as measured by gingival pocket depth. Physical disability was indicated by the subject's self-report of difficulty in the areas of personal care (eating, bathing, dressing, and using the toilet) and mobility (walking, bed transfer, getting outside). Additional independent variables included age, sex, number of teeth, education, living alone, oral hygiene practices, and time since last dental visit.


RESULTS
We found a direct association between specific areas of physical disability and current caries and edentulism. The risk of poor oral health did not increase with advancing age once the related risk factors were controlled for. Those subjects with mobility disabilities were at increased risk of tooth loss; those with personal care limitations were at increased risk of current caries.


CONCLUSIONS
Physical disability should be added to the list of known risk factors for oral disease among the older population. Our findings call attention to the need for health care providers to screen for oral health problems among disabled older persons. Further gerontologic research is needed to identify the mechanisms linking physical disability with oral disease in older persons.
