Kim and Park: The Risk of Dysphagia and Dysphagia-specific Quality of Life among Community Dwelling Older Adults in Senior Center

Abstract

Purpose

The aim of this study was to describe the risk of dysphagia among older adults in senior centers and to find therelationshipsbetween the risk of dysphagia and dysphagia-specific qualityof life.

Methods

Theparti-cipantswere 260 community-dwellingolder adults, aged 65 years in two senior centers. Data werecollected by self-report questionnaires or face to face interviews. The instruments were the modified dysphagia risk assessment scale for elderly and dysphagia-specific quality of life questionnaire. The data were analyzed using t-test, x2-test, logistic regression, andpearson's correlation.

Results

162olderadults (62.3%) wereclassifiedashaving the risk of dysphagia. Severe dry mouth (OR=15.677, CI=2.986~82.297), neurologic disease (OR=10.125, CI= 1.092~93.899), gastritis (OR=5.731,CI=1.482~22.173), denture discomfort (OR=2.969, CI=1.016~8.677), teeth discomfort (OR=2.61, CI=1.311~5.196) were the significant factors predicting the risk of dysphagia. There is a significant correlationbetweenthe riskof dysphagia and dysphagia-specificquality of life.

Conclusion

Dysphagia could be a major health problem among community dwelling older adults. It can affect the dysphagia-specific quality of life. Older adults having severe dry mouth, neurologic disease, or gastritis should receive dysphagia risk assessment and proper management on a regular basis. An effective nursing intervention needs to be developed for the older adults with risk factors of dysphagia.
