General health-related quality of life and oral health impact among Australians with cleft compared with population norms; age and gender differences

Abstract

OBJECTIVE: To evaluate general health-related quality of life (HRQoL) and oral health impact among adults treated for cleft to determine age and gender differences, and to compare against population norms. DESIGN: Cross-sectional prospective study. PARTICIPANTS/SETTING: Nonsyndromic cleft patients treated by the Australian Craniofacial Unit from 1975 to 2009 were recruited (n = 112). Response rate was 79% (n = 88). MAIN OUTCOME MEASURES: HRQoL was measured by the Short Form (SF)-36 questionnaire. Oral health impact was measured by the Oral Health Impact Profile (OHIP)-14 questionnaire. Statebased and national norms were used for comparative purposes. RESULTS: There were no significant age or sex differences in the cleft sample’s SF-36 and OHIP-14 scores. When compared against South Australian 2002 state-level norms, cleft participants scored higher on physical function and physical role function but lower on vitality and mental health. The prevalence of having experienced one or more of OHIP–14 items "fairly often" or "very often" was 2.7 times higher than national-level estimates, while extent was 2.8 times and severity 1.7 times higher. CONCLUSIONS: The oral health impact among cleft patients included in our study was poor compared with population-level estimates. The HRQoL showed mixed results, with the vitality and mental health components being poorer in the cleft group compared with population-level estimates. These results indicate that treatment for orofacial clefting does not entirely remove the factors contributing to poor HRQoL and oral health.
