- Characterization of the oral health status and literacy among a sample of Portuguese elderlyPublication . Costa, Hélder; Veiga, Nélio; Correia, Patrícia; Couto, Patrícia; Correia, Maria José; López-Marcos, JoaquínBackground Health literacy is a main factor in health for its improvement, allowing the individuals to have a greater capacity to engage and participate in collective health promotion actions. In dentistry, oral health literacy (OHL) is the ability to understand information regarding dental services, as well as the prevention, control, and treatment of oral problems. The aim of this study was to characterize the oral health status, behaviors and oral health literacy of a sample of participants in the “Atividade Senior” program developed by the municipality of Viseu, Portugal. Materials and methods An observational cross-sectional study was designed with a sample of 206 participants of the program that accepted responding to the questionnaire and the application of the Rapid Estimate of Adult Literacy in Dentistry (REALD-29PT), validated for the Portuguese population. An intra-oral observation was accomplished to determine the oral health status of the participant and the decayed, missing and filled teeth index was determined (DMFT index). All the participants signed an explicit and informed consent, and the research was approved by the Health Ethics Committee of the Universidade Católica Portuguesa, with the approval registration number 100. Results As for gender, 69.4% (n=143) are women and 30.6% (n=63) men, with an average age of 70.0±7.16. Regarding oral health behaviors, 31.7% brush once a day, 81.6% do not use dental foss nor other methods of interdental hygiene and 55.8% had a dental appointment in the last 12 months. The DMFT index was 10.38±8.55, with the higher score corresponding to the missing teeth component (11.96±8.56) and 43.9% of the sample use a dental prothesis. Regarding the application of the REALD-29PT, we can verify that 22.7% have low OHL (score from 0-14), 43.7% moderate OHL (score from 15-22) and 33.6% high OHL (score 23-29). Conclusions Oral health literacy presents a satisfactory level among more active older adults. However, the reinforcement of oral health promotion strategies is needed to improve oral health status and literacy among the community. These strategies should pass by the development of teaching methods based on oral health behaviors for the community and the implementation of oral health promotion programs directed to adults.
- Validity and reliability of the Portuguese version of the rapid estimate of adult literacy in dentistry - REALD-29 PTPublication . Costa, Hélder; Amaral, Odete; Duarte, João; Correia, Maria José; Veiga, Nélio; López-Marcos, Joaquín FranciscoBackground: Health literacy is a main factor in health for its improvement, allowing the individuals to have a greater capacity to engage and participate in collective health promotion actions. The assessment of functional health literacy to determine the ability that each individual has to understand basic health information is essential. The aim of the present study was to translate and perform the cross-cultural adaptation of the Rapid Estimate of Adult Literacy in Dentistry (REALD-30) to Portuguese language and test the reliability and validity of this version. Method: The REALD-30 in the Portuguese language (REALD-29 PT) was applied to a group of individuals that participate in the program Atividade Senior, developed by the municipality of Viseu, Portugal. The final sample was composed by 206 participants that accepted responding to the questionnaire and to the REALD-30 Portuguese version (REALD-29 PT). Translation and cultural adaptation of the questionnaire and the statistical validation was accomplished in order to complete the process and obtain the REALD-29 PT. Results: The REALD-29 PT presented good internal reliability. Cronbach’s alpha ranged from 0.89 to 0.90 when words were deleted individually. The analysis of test-retest reliability revealed excellent reproducibility. We can verify that the REALD-30 scale for assessment of oral health literacy among older adults presents an acceptable internal consistency, with a global Cronbach´s alpha of 0.894. Conclusions: The REALD-29 PT scale can be applied to assess oral health literacy among older Portuguese adults, presenting an acceptable internal consistency and is validated to assess oral health literacy and is crucial in epidemiological studies.

Costa, Hélder; Amaral, Odete; Duarte, João; Correia, Maria José; Veiga, Nélio Jorge; López-Marcos, Joaquin FranciscoBackground: Health literacy is a main factor in health for its improvement, allowing the individuals to have a greater capacity to engage and participate in collective health promotion actions. The evaluation of functional health literacy is essential to determine the ability that each individual has to understand basic health information. The present study aimed to perform the translation and cross-cultural adaptation of the Rapid Estimate of Adult Literacy in Dentistry-30 to the Portuguese language and test the reliability and validity of this version. Methods: After translation and cultural adaptation, the instrument was applied to a group of individuals that participate in the program Atividade Senior, developed by the municipality of Viseu, Portugal. The final sample was composed by 206 participants that accepted responding to the translated version of the instrument. Statistical validation was accomplished to complete the process and obtain the final instrument. One question was removed for the creation of the final instrument with 29 questions, therefore being named Rapid Estimate of Adult Literacy in Dentistry-29 PT. Results: The Rapid Estimate of Adult Literacy in Dentistry-29 PT presented good internal reliability. Cronbach’s alpha ranged from 0.89 to 0.90 when words were deleted individually. The analysis of test–retest reliability revealed excellent reproducibility. We can verify that the Rapid Estimate of Adult Literacy in Dentistry-29 PT scale for assessment of oral health literacy among older adults presents an acceptable internal consistency, with a global Cronbach´s alpha of 0.894. Conclusions: The new scale can be applied to assess oral health literacy among older Portuguese adults, presenting an acceptable internal consistency and is validated to assess oral health literacy and is crucial in epidemiological studies.
