Factors Associated with Self-reported Oral Health Among Community-Dwelling Older Adults in a Rural Province of Thailand

Abstract

Background: Limited research has focused on self-reported oral health in older Thai individuals. Objective: We explored the factors associated with self-reported oral health among older adults residing in rural Thailand. Methods: This cross-sectional study included males and females aged ≥ 60 years living in Phon Thong district, Roi Et province, a rural area in northeast Thailand. This community-based study was conducted between May 2021 and December 2021. A trained interviewer administered a face-to-face interview questionnaire. Study data were analyzed using descriptive statistics, Pearson’s chi-squared test, and binary logistic regression. Results: In total, 249 older individuals completed the interviews. Most study participants were aged ≥ 67 years (55.8%), with a mean age of 66.92 years. Pearson’s chi-squared test showed statistically significant associations between self-reported oral health and age (P = 0.035) and chewing ability (P = 0.005). The multivariate binary logistic regression analysis revealed significant associations between self-reported poor oral health and older age (AOR = 0.290, 95% CI: 0.091–0.925) and chewing discomfort (AOR = 4.032, 95% CI:1.119–14.56). We observed no significant associations between self-reported oral health and sex, toothbrushing frequency, and speaking ability. Conclusion: Younger respondents with chewing discomfort were more likely to self-report poor oral health. In rural areas, nonprofessional health providers can use a single-item self-reported oral health question as a simple tool for evaluating oral health status in the elderly. Moreover, dental health education programs are needed to help older individuals improve their oral self-care, access dental services, and achieve appropriate oral function. Such programs are essential for promoting good oral health in this population, particularly among “younger” elders.
