Abstract

Objectives: The study assessed the association between socio-economic status (SES) and oral health-related quality of life (OHRQoL) for elderly Koreans, and determined the role of oral health status, oral health behaviors and general health status on this association using multi-variate logistic regression models.
Methods: The study population was elderly (≥65-years-of-age) residents of Wonju-City, Gangwon province recruited from five elder welfare institutions. Education level and household income were selected as measures of SES. To assess socio-economic inequalities in OHRQoL, multi-variable logistic regression models were used. A model adjusting for socio-demographic factors (ModelI) was compared to models additionally adjusting for oral health behaviors (Model II), oral health status (Model III), general health status (Model IV) and all factors (Model V).
Results: One hundred fifty nine people were invited to participate, and the response rate was 97.5% (n=155). Lower SES was significantly associated with lower score of OHRQoL. Oral health behaviors, oral health status and general health status explained part of the social inequalities in OHRQoL. The social gradient score of OHRQoL persisted when adjusted for oral health behaviors, oral health status and general health status.
Conclusions: An association between SES and OHRQoL was evident for elderly Koreans. Oral health behaviors, oral health status and general health status were factors affecting the association. Longitudinal research is required to determine the specific role of the association between SES and OHRQoL.
