Abstract The present study aimed to perform the cross-cultural adaptation of the Digital Health Literacy Instrument (DHLI) for native Brazilian Portuguese-speaking adolescents (DHLI-BrA). Cross-cultural adaptation consisted of the following steps: translation, assessment, and adjustments by the expert committee to ensure cultural equivalence; back-translation, and synthesis of back-translations. Cognitive testing was then performed in a pretest with adolescents using cognitive interviews with probing questions on the item's understanding interpretation and response options. Cronbach’s alpha coefficient and McDonald’s omega were used to estimate the instrument’s reliability. Forty-two Brazilian adolescents participated in the study (mean age: 16.0 ± 2.0 years; range: 13 to 19 years). Items that were difficult to understand were adapted to the context of Brazilian adolescents. Cronbach’s alpha coefficient and McDonald’s omega for the 21 items of the DHLI-BrA were, respectively, 0.79 and 0.80. Cronbach’s alpha coefficient for the subscales of the self-report instrument was 0.53-0.79 (range), demonstrating good reliability in the total instrument and moderate reliability in the subscales. This study provides the cross-cultural adapted version of the Digital Health Literacy Instrument (DHLI), which is an instrument for measuring digital Health literacy, for use in Brazilian adolescents (DHLI-BrA).

Resumo O estudo teve o objetivo de adaptar transculturalmente o Digital Health Literacy Instrument (DHLI) para adolescentes nativos do idioma português do Brasil (DHLI-BrA). O estudo de adaptação transcultural consistiu nas seguintes etapas: tradução, avaliação e adequação de equivalência cultural da tradução por comitê de especialistas; retrotradução e síntese das retrotraduções. Foi realizada a testagem cognitiva em pré-teste com adolescentes, utilizando-se entrevistas cognitivas com perguntas de sondagem sobre a compreensão e interpretação dos itens e opções de resposta. O alfa de Cronbach e ômega de McDonald’s foram utilizados para estimar a confiabilidade do instrumento. Participaram do pré-teste 42 adolescentes brasileiros com média de idade de 16,0 ± 2,0 (variação de 13-19) anos. Os itens com dificuldade de compreensão foram adaptados ao contexto dos adolescentes brasileiros. O coeficiente alfa de Cronbach e o ômega de McDonald’s, para os 21 itens do DHLI-BrA foi respectivamente, 0,79 e 0,80. O coeficiente alfa de Cronbach para as subescalas do instrumento de autorrelato foi de 0,53-0,79 (variação), demonstrando boa confiabilidade no instrumento total e confiabilidade moderada nas subescalas. Este estudo fornece a versão adaptada transculturalmente do Digital Health Literacy Instrument (DHLI), um instrumento de mensuração do letramento digital em saúde, para utilização em adolescentes brasileiros (DHLI-BrA).

Abstract The aim of the present study was to investigate the impact of oral health literacy (OHL) on conceptions of care and behaviors related to COVID-19. The sample came from two preliminary cross-sectional studies that determined the level of OHL of parents/guardians of six-to-12-year-old children in two major Brazilian cities (Curitiba and Belo Horizonte). Functional OHL was measured using the Brazilian version of the Rapid Estimate of Adult Literacy in Dentistry (BREALD-30) and the Health Literacy Dental Scale (HeLD-14) for the evaluation of interactive OHL. Participants were recruited through e-mail, social media, and telephone contact. The questionnaire on conceptions of care and behaviors related to COVID-19 was created based on the guidelines of the World Health Organization. Two hundred nineteen individuals participated in the study. There was no significant difference in socioeconomic and demographic variables and in the medians of BREALD and HeLD-14 between the two cities (P>0.05). Higher levels of functional OHL were associated with an appropriate conception that individual care affects collective care (P=0.038), but with an inappropriate conception of seeking medical assistance in cases of mild symptoms (P=0.030). Higher levels of interactive OHL were related to social distancing behavior in the city of Curitiba (P=0.049) and in the overall sample (P=0.040). It is concluded that functional OHL was associated with two of the investigated conceptions about COVID-19, while interactive OHL was associated with social distancing behavior. These data may suggest that different dimensions of the OHL can have an impact on different aspects of coping with the pandemic.

Abstract Background Patients with chronic renal failure may have their oral health impaired as a result of the disease itself, its treatment, and its associated lifestyle alterations. Objective To assess the factors associated with poor self-rated oral health among adults with chronic renal failure treated by hemodialysis. Method This is a cross-sectional study with 243 adults undergoing hemodialysis in a hospital in Minas Gerais, Brazil in 2013-2014. The outcome was assessed by the self-report of oral health categorized into good (excellent/good) and bad (fair/bad / very bad). The independent variables included sociodemographic conditions, general health, oral health, and the use of dental services were collected through a structured questionnaire. The association between the outcome and the independent variables was tested using multiple logistic models with hierarchical inclusion of variables. Results The prevalence of poor self-rated oral health was 35.4%. The youngest (p = 0.015), those who have undergone hemodialysis in the shortest time (p = 0.016), have halitosis (p <0.001), need dental treatment (p <0.001), and had their last dental appointment not for pain (p = 0.027) expressed higher odds of poor self-rated oral health, independently of sociodemographic and health conditions. Conclusion Sociodemographic conditions, time on hemodialysis, oral impairments, and use of dental services affected the oral health self-assessment among adults undergoing hemodialysis.

Resumo Introdução Pacientes com insuficiência renal crônica podem apresentar prejuízos em sua saúde bucal em decorrência da própria doença, do tratamento e das alterações de estilo de vida associadas. Objetivo Avaliar os fatores associados à autoavaliação de saúde bucal ruim entre adultos com insuficiência renal crônica submetidos à hemodiálise. Método Estudo transversal com 243 adultos submetidos à hemodiálise em um hospital do sul de Minas Gerais nos anos de 2013 e 2014. O desfecho foi avaliado pelo autorrelato da condição bucal dicotomizada em boa (ótima/boa) e ruim (regular/ruim/péssima). As variáveis independentes incluíram condições sociodemográficas, saúde geral, saúde bucal e uso de serviços odontológicos, a partir de informações coletadas por meio de questionário. A associação entre o desfecho e as variáveis independentes foi testada por meio de modelos logísticos múltiplos com inclusão hierarquizada de variáveis. Resultados A prevalência de autoavaliação de saúde bucal ruim foi de 35,4%. Os mais jovens (p = 0,015), os que se submetem à hemodiálise há menos tempo (p = 0,016), têm halitose (p <0,001), necessitam de tratamento odontológico (p <0,001) e tiveram a última consulta odontológica por motivo diferente de dor (p = 0,027) expressaram maiores chances de autoavaliação de saúde bucal ruim, independentemente de condições sociodemográficas e de saúde. Conclusão Condições sociodemográficas, tempo em hemodiálise, agravos à saúde bucal e uso de serviços odontológicos influenciaram a autoavaliação da saúde bucal dos adultos submetidos à hemodiálise.
