Cross-cultural differences in oral impacts on daily performance between Greek and British older adults.

OBJECTIVE

To examine whether there are significant cross-cultural differences in oral health-related quality of life and perceived treatment need between older people of similar clinical oral status living in Greece and Britain.

BASIC RESEARCH DESIGN

Cross-sectional surveys of adults living independently aged 65 years or older. In Britain, data from the national diet and nutrition survey were used, while the Greek sample was drawn from two municipalities in Athens. Participants 753 in Britain and 681 in Greece.

MAIN OUTCOME MEASURES

Oral health-related quality of life, assessed through the modified Oral Impacts on Daily Performance (OIDP) indicator, and perceived need for dental treatment.

RESULTS

Thirty-nine per cent of Greek and 12.3% of British dentate and 47.6% of Greek and 16.3% of British edentulous participants had experienced oral impacts affecting their daily life in the last six months. The most prevalent impact was difficulty eating. Apart from that, 56.3% of Greek and 37.1% of British dentate and 33.5% of Greek and 25.3% of British edentulous participants perceived dental treatment need. After controlling for sociodemographic variables, perceived general health and clinical oral status, Greek dentate and edentulous participants were significantly more likely to experience oral impacts than their British counterparts, while in relation to perceived treatment need significant cross-cultural differences existed only between dentate respondents.

CONCLUSIONS

The results indicated an independent cultural influence in the perception of oral impacts in older people.
