Development and Validation of a Protocol for Pregnant Women Based on the Brazilian Dietary Guidelines

Abstract

Objective To develop and validate a protocol for the use of the Dietary Guidelines for the Brazilian Population (DGBP) in the individual dietary advice for pregnant women assisted in primary healthcare (PHC).

Methods Methodological study that involved the elaboration of a protocol in six steps: definition of the format, definition of the instrument to evaluate food consumption, systematization of evidence on food and nutrition needs of pregnant women, extraction of DGBP recommendations, development of messages of dietary guidelines and content, and face validity. The analyses of the validation steps were carried out by calculating the Content Validity Index (CVI) and thematic content analysis.

Results As products of the steps, the protocol structure was defined and the dietary advice for pregnant women were elaborated, considering physiological changes, food consumption, nutritional and health needs, and socioeconomic conditions of this population. The protocol was well evaluated by experts and health professionals in terms of clarity, relevance (CVI > 0.8), and applicability. In addition, the participants made some suggestions to improve the clarity of the messages and to expand the applicability of the instrument with Brazilian pregnant women.

Conclusion The instrument developed fills a gap in clinical protocols on dietary advice for pregnant women focused on promoting a healthy diet, contributing to a healthy pregnancy. In addition, it demonstrates potential to contribute to the qualification of PHC professionals and to the implementation of the DGBP recommendations.

Resumo

Objetivo Desenvolver e validar um protocolo para uso do Guia Alimentar para a População Brasileira (GAPB) na orientação alimentar individual de gestantes atendidas na atenção primária à saúde (APS).

Métodos Estudo metodológico que envolveu a elaboração de um protocolo em seis etapas: definição do formato do documento, definição do instrumento de avaliação do consumo alimentar, sistematização de evidências sobre necessidades de alimentação e nutrição de gestantes, extração das recomendações do GAPB, desenvolvimento de mensagens de orientação alimentar e validação de conteúdo e validação aparente. As análises das etapas de validação foram realizadas através do cálculo do índice de validade de conteúdo e análise temática de conteúdo.

Resultados Como produtos das etapas, a estrutura do protocolo foi definida e as orientações alimentares de gestantes foram elaboradas, considerando as alterações fisiológicas, consumo alimentar, necessidades nutricionais e de saúde e condições socioeconômicas desta população. O protocolo foi bem avaliado por especialistas e profissionais de saúde nos critérios de clareza, pertinência (índice de validade de conteúdo > 0,8) e aplicabilidade. Além disso, os participantes deram sugestões para melhoria da clareza das mensagens e para ampliar a aplicabilidade do instrumento em gestantes brasileiras.

Conclusão O instrumento desenvolvido preenche uma lacuna sobre protocolos clínicos de orientação alimentar para gestantes focado na promoção da alimentação saudável, contribuindo para uma gestação saudável. Além disso, o instrumento demonstra potencial para contribuir na qualificação de profissionais da APS e implementação das recomendações do GAPB.
