The association of socio-economic status, dental anxiety, and behavioral and clinical variables with adolescents’ oral health-related quality of life

Purpose It is not clear which factors hold more weight in predicting oral health-related quality of life (OHRQoL). Therefore, this study explored which component of factors (e.g., socio-economic status, clinical status or oral health behaviors, dental anxiety, oral health knowledge) has a better pre...

Description
Summary:Purpose It is not clear which factors hold more weight in predicting oral health-related quality of life (OHRQoL). Therefore, this study explored which component of factors (e.g., socio-economic status, clinical status or oral health behaviors, dental anxiety, oral health knowledge) has a better predictive value in different aspects (e.g., oral symptoms, functional limitations, social and emotional conditions) of adolescents’ OHRQoL. Methods Participants were randomly selected from Grade Two (S2) students within 12 secondary schools in Hong Kong. The independent variables include the following : socio-economic (monthly family income, parents’ educational background), oral health behaviors (the frequency of brushing and having snacks like chocolate or biscuits), and oral health-related factors (oral health knowledge, dental anxiety, dental caries and bleeding index). Adolescents’ OHRQoL was evaluated using the 16-item Child Perception Questionnaire (CPQ 11-14 -ISF:16). Frequencies and means were used for data description. Different variables were analyzed as predictors of OHRQoL by multi-level linear regression analysis. Results 1207 adolescents (46.6% females) participated in this study. The mean total CPQ 11-14 -ISF:16 was 14.2 (9.8). Mean scores of oral symptoms, functional limitations, and emotional and social well-being were 4.4 (2.8), 4.2 (2.8), 3.2 (3.1), and 2.4 (2.7), respectively. In the final model, adolescents with poorer oral health knowledge, higher dental anxiety levels, brushed their teeth less than once a day and consumed chocolates or biscuits more regularly as reported by a statistically worse OHRQoL ( p
