Associations between Indigenous Australian oral health literacy and self-reported oral health outcomes

Abstract

ObjectivesTo determine oral health literacy (REALD-30) and oral health literacy-related outcome associations, and to calculate if oral health literacy-related outcomes are risk indicators for poor self-reported oral health among rural-dwelling Indigenous Australians.Methods468 participants (aged 17-72 years, 63% female) completed a self-report questionnaire. REALD-30 and oral health literacy-related outcome associations were determined through bivariate analysis. Multivariate modelling was used to calculate risk indicators for poor self-reported oral health.ResultsREALD-30 scores were lower among those who believed teeth should be infrequently brushed, believed cordial was good for teeth, did not own a toothbrush or owned a toothbrush but brushed irregularly. Tooth removal risk indicators included being older, problem-based dental attendance and believing cordial was good for teeth. Poor self-rated oral health risk indicators included being older, healthcare card ownership, difficulty paying dental bills, problem-based dental attendance, believing teeth should be brushed infrequently and irregular brushing. Perceived need for dental care risk indicators included being female and problem-based dental attendance. Perceived gum disease risk indicators included being older and irregular brushing. Feeling uncomfortable about oro-facial appearance risk indicators included problem-based dental attendance and irregular brushing. Food avoidance risk indicators were being female, difficulty paying dental bills, problem-based dental attendance and irregular brushing. Poor oral health-related quality of life risk indicators included difficulty paying dental bills and problem-based dental attendance.ConclusionsREALD-30 was significantly associated with oral health literacy-related outcomes. Oral health literacy-related outcomes were risk indicators for each of the poor self-reported oral health domains among this marginalised population.

Understanding health talk in an urban Aboriginal and Torres Strait Islander primary healthcare service: a cross-sectional study

“…Strait Islander people is limited to a few studies identifying an association between inadequate dental health literacy and poorer dental health outcomes among Aboriginal Australians residing in rural South Australia (Jamieson et al 2008;Parker and Jamieson 2010;Jamieson et al 2013). Assessment of health literacy will provide some indication of the prevalence of adequate health literacy, increase health professionals' awareness of the need to provide health information that is easily understood by patients and assist Indigenous Australians to better manage their illness.…”

Caregivers’ Health Literacy and Their Young Children’s Oral-health–related Expenditures

“…Accumulating evidence suggests that health literacy also has a pivotal role in the context of oral health (Horowitz and Kleinman, 2008;Parker and Hernandez, 2012). Recent studies have detected links between lower literacy and poor outcomes in the domains of oral health status (Parker and Jamieson, 2010;Lee et al, 2012;Wehmeyer et al, 2013), knowledge (Macek et al, 2010), and quality of life .…”

The Determinants of Self–Rated Oral Health in Istanbul Adults

“…Recent studies suggest that health literacy is associated with educational attainment in self-rated health and in regular dental attendance pattern among older adults (Bennett et al, 2009). In addition, oral health literacyrelated outcomes are risk indicators for poor self-reported oral health among rural-dwelling Indigenous Australians (Parker & Jamieson, 2010). We found that adults who were married were more likely to report good SROH.…”
