Oral Status and its Association with Oral Health-Related Quality of Life in Community-Dwelling Older Adults

ABSTRACT

Poor oral conditions among older adults can cause significant impacts to their overall quality of life. Older adults with reduced number of functional teeth and dental diseases may experience difficulty in daily activities like chewing and eating. The aim of this study is to assess the association between oral health and oral health-related quality of life (OHRQoL) among a group of community-dwelling older adults in Negeri Sembilan, Malaysia. A cross-sectional study was carried out on 436 older adults aged 50 years and above from 20 randomly selected villages in the state. Respondents were interviewed using a structured questionnaire to collect information on their demographic characteristics. Clinical oral examination was carried out to determine the oral health conditions of older people. The validated Malay version of Geriatric Oral Health Assessment Index (GOHAI) was used to measure OHRQoL. Total GOHAI score ranged from 12 to 60 with higher scores indicate better OHRQoL. Majority (77.1%) of the older adults had less than 20 teeth and about 18.3% were edentulous (total tooth loss). All dentate respondents had experienced dental caries. The median GOHAI score was 54.5 (IQR 50-57). About 25.5% of the older adults perceived their oral health as good, while 74.5% had poor perception on oral health. Bivariate analysis showed that less than 20 teeth and high dental caries experience were significantly associated with poor OHRQoL. A significantly higher proportion of older adults with less than 20 teeth limit the kinds of food intake, had trouble biting or chewing, and experienced tooth sensitivity. The physical functioning and well-being of the older people may be disrupted due to oral diseases. Measures of OHRQoL are important as to complement the clinical oral findings in identifying treatment needs of the geriatric patients.
