Manual das cantinas escolares saudáveis: revisão e validação de conteúdo

Abstract

Introduction: Obesity in childhood and adolescence has increased significantly over the years, as a result of several individual and environmental factors. The sale of ultra-processed foods and drinks in school canteens has been an aggravating factor. Technical materials with updated national guidelines can favor the implementation of healthy school canteens, encouraging better food choices among children and adolescents in the school environment. Objectives: To validate the content of the second edition of the “Healthy School Canteens Manual: promoting healthy eating”. Methods: Methodological study, developed in five stages: 1) bibliographical survey in the main scientific databases and national institutional repositories; 2) updating the content of the material; 3) review of the content by researchers involved with the theme of each chapter; 4) review of the material by the General Coordination of Food and Nutrition (CGAN/MS); 5) content validation by a panel of experts on the subject and Communication and Language professionals from the five regions of the country. Validation data was collected through an online questionnaire, with response options based on a Likert scale. In data analysis, descriptive statistics were used for the specialists' sociodemographic data and Content Validity Coefficient (CVC) for each item (CVCi), for each domain (CVCd) and for the complete material (CVCf), with a cutoff point equal to 0.80. Items related to the Objectives, Relevance and Language domains were evaluated. Results: The content of the second edition of the Manual was validated by 11 expert judges on the themes of school food environment and promotion of adequate and healthy eating and by five Communication or Language professionals. For the objective, relevance and language domains, CVCs of 0.93, 1.0 and 0.87 were obtained, respectively. The final CVC was 0.93. Final considerations: The updated and validated document is suitable for the school community and could contribute to the implementation of healthy school canteens, being a powerful tool for transforming these spaces into places to promote adequate and healthy eating in the school environment.
