The Nutrition Literacy Assessment Instrument for Brazilians, NLit-Br: An Exploratory Cross-Cultural Validity Study.

This study aimed to test the validity of the cross-cultural adapted Nutrition Literacy Assessment Instrument for Brazilians (NLit-Br). An observational cross-sectional study was performed in chronic disease clinics from the Brazilian Public Health System in two phases: (1) linguistic and cultural adaptation and (2) validity testing. Six registered dietitians and thirty adult patients diagnosed with at least one chronic disease participated in the study using the nutrition literacy assessment instrument (NLit-Br) and the short assessment of health literacy for Portuguese-speaking adults (SAHLPA-18). Sample descriptive variables: age, sex, race, income, education, and occupation. To adapt the instrument to the Brazilian Portuguese and Brazilian culture, we tested cognitive interviewing and the Scale Content Validity Index (S-CVI) with a group of dietitians and patients. To test the tool's validity, health literacy (SAHLPA-18) was used as a construct that presents similarities and differences with nutrition literacy (NLit-Br). The correlation of NLit-Br and the SAHLPA-18 was tested (Spearman's Rho). Internal consistency was measured by Kuder−Richardson Formula 20 (KR-20). The NLit-Br content validity (S-CVI = 0.85) and internal consistency (KR-20 = 0.868) were confirmed. Additionally, NLit-Br presented a significant and robust correlation with SAHLPA-18 (r = 0.665, p < 0.001). Therefore, the NLit-Br was considered a linguistic, cultural, and valid instrument to measure Brazilian's nutrition literacy.

Metodologia de criação de uma ferramenta didáticopedagógica de intervenção em doença renal crônica, segundo preceitos do letramento em saúde / Methodology of creating a pedagogic-didactic tool for intervention in chronic kidney disease, precepts of health literacy

Considerando que o diagnóstico precoce da doença renal crônica (DRC) e o sucesso terapêutico da doença primária são fundamentais para a diminuição ou reversão da progressão da DRC, são necessárias intervenções que irão impactar positivamente conforme a precocidade de sua aplicação. O objetivo do presente trabalho foi desenvolver uma ferramenta didático pedagógica de intervenção em DRC. A criação da Ferramenta obedeceu a cinco etapas iniciais: sistematização do conteúdo; criação das imagens por um designer especializado; diagramação e edição do conteúdo; submissão a um Comitê de Especialistas e criação de um Manual do Mediador. A Ferramenta Didática de Intervenção em DRC foi concluída, dando origem a um instrumento capaz de abordar 11 itens de extrema importância para o tratamento da DRC: (1) Você sabe o que é Doença Renal Crônica?; (2) Acolhimento; (3) Sentimentos mediante o diagnóstico; (4) Definição de DRC; (5) Caminho do sangue; (6) Mitos e verdades; (7) Sinais e sintomas; (8) Fatores de risco; (9) Alimentação; (10) Atividade física; e (11) Tratamento. A Ferramenta Didático-Pedagógica de Intervenção em DRC é um instrumento facilitador da aprendizagem, por ter uma estrutura lúdica, dialógica e dinâmica, cujo intuito é impactar nos desfechos de forma positiva.

Considering that the early diagnosis of chronic kidney disease (CKD) and the therapeutic success of the primary disease are fundamental for the reduction or reversal of the progression of CKD, early interventions are required in order to positively impact in course of the disease. The objective of this study was to develop a pedagogical didactic tool for intervention in CKD. The development of the Tool obeyed five initial stages: systematization of the content; creation of images by a specialized designer; layout and content editing; submission to a Committee of Experts, and creation of a Manual of the Mediator. The Didactic Intervention Tool in DRC was completed, originating an instrument capable of addressing 11 items of extreme importance for the management of CKD: (1) Do you know what is Chronic Renal Disease ?; (2) Reception; (3) Feelings through diagnosis; (4) Definition of DRC; (5) Blood flow through the kidneys; (6) Myths and truths; (7) Signs and symptoms; (8) Risk factors; (9) Eating; (10) Physical activity; and (11) Treatment. The DidacticPedagogical Intervention Tool in DRC is an instrument that facilitates learning, because it has a playful, dialogic and dynamic structure, that aims to positively impact in the outcomes of the disease.
