Abstract
OBJECTIVES: This study aims to assess the oral health-related quality of life (OHRQoL) among the Irula tribes and to know the factors influencing quality of life among the elderly irula tribes of Tamil Nadu. METHODS: This cross-sectional study was conducted in the Northern district of Tamil Nadu, including 486 Irula individuals aged 65 and above. Participants were selected using a multistage sampling method. Data were collected through a structured questionnaire, including the Geriatric Oral Health Assessment Index (GOHAI) to evaluate OHRQoL. The study tool covered demographics, medical history, and oral health issues. Data analysis was performed using SPSS version 23, with logistic regression applied to account for confounders. RESULTS: The sample primarily consisted of individuals aged 65-69 years (55.6%), with a predominance of females (76.3%). The majority were Hindu (94.9%) and lived in nuclear families (88.3%). Educational levels were low, with 66.5% being illiterate. Most participants were agricultural laborers (64.6%) and had low monthly incomes. GOHAI results revealed that many respondents faced significant oral health challenges, including difficulties with eating, speaking, and discomfort. Multivariate analysis showed that educational level significantly affected OHRQoL, with higher education correlating with better quality of life. Arthritis was associated with poorer OHRQoL, while other health conditions did not show significant impacts. CONCLUSION: The study highlights severe oral health issues among the Irula community, with significant physical and psychological impacts. Educational attainment plays a crucial role in OHRQoL, while arthritis notably affects quality of life. The findings emphasize the need for targeted oral health interventions and increased awareness in tribal communities to improve overall health outcomes. Further research in larger populations is necessary to comprehensively understand and address geriatric oral health needs.
