RESUMO
Objectives: Oral health literacy (OHL) is suggested as an important denominator of oral health. This study aimed to identify ways to improve oral health by exploring the association between oral health literacy and oral health-related behaviours among female adolescents in the Eastern Province of the Kingdom of Saudi Arabia (KSA). Methods: This cross-sectional study assessed OHL among 1,889 10th grade female students in the Eastern Province of the KSA. OHL was assessed using an Arabic version of the short version of the Health Literacy in Dentistry scale (A-HeLD-14). Self-reported socio-demographic information and oral health-related behaviours (toothbrushing, dental attendance, and sugary diet consumption) were also collected. The relationship between OHL and oral health-related behaviours was investigated using binary logistic regression, adjusted for socio-demographic information. Results: The binary logistic regression analyses showed that poor OHL was significantly associated with infrequent toothbrushing (p < 0.001) and irregular dental attendance (p = 0.005) but not with consumption of sugary diets. All A-HeLD-14 domains were significantly associated with infrequent toothbrushing, and the domains concerning access, receptivity, and financial barriers were significantly associated with irregular dental attendance. The highest odds ratios (ORs) for infrequent toothbrushing were found in the domains of receptivity (OR = 4.19) and understanding (OR = 3.85) and for irregular dental attendance in the financial barriers (OR = 1.61) and access (OR = 1.49) domains, followed by the receptivity domain (OR = 1.35). Conclusion: Poor OHL was significantly associated with infrequent toothbrushing and irregular dental attendance. Interventions focusing on OHL are warranted to improve oral health-related behaviours and thereby oral health in the population. The aspects that seem most vital to target are improved access to dental care, including the reduction of economic barriers, as well as increased awareness of oral health in the population.
RESUMO
BACKGROUND: The Arabic version of the short form of the Health Literacy in Dentistry scale (HeLD) had not yet been developed in previously published studies. This study aims to test the reliability and validity of an Arabic version of the short form of the HeLD questionnaire. METHODS: The short version of HeLD was translated into Arabic and the psychometric properties were evaluated in a sample of 1,889 female students in their first year of secondary school. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC), and internal consistency reliability was assessed using Cronbach's alpha. Content validity was investigated by creating a correlation matrix between the individual items of the HeLD-14, and criterion validity was determined using Pearson's correlation between the HeLD-14 score and an overall oral health rating. Sensitivity analysis was assessed by testing the associations of the HeLD-14 score with oral health-related behaviours and residential area. RESULTS: The Arabic version of HeLD-14 (A-HeLD-14) had acceptable ICC (0.54) and excellent internal consistency (Cronbach's alpha: 0.92). The correlations between the items of the A-HeLD-14 varied from 0.3 to 0.9. The A-HeLD-14 showed a statistically significant correlation with the overall oral health rating (r = 0.37, p < 0.001). The median A-HeLD-14 score was significantly higher in participants who brushed their teeth frequently (51.31), visited the dentist regularly (52.00), consumed fresh fruit frequently (51) and consumed soda or energy drinks infrequently (51.00) than participants who brushed their teeth infrequently (41.50), visited the dentist irregularly (49.00), consumed fresh fruit infrequently (47) and consumed soda or energy drinks frequently (48.00). CONCLUSION: The A-HeLD-14 instrument demonstrates sufficient validity, reliability, and sensitivity for measuring oral health literacy among the Arabic-speaking population.
