Abstract

The objective of this study was to identify and discuss the tools for the promotion and evaluation of adequate and healthy eating based on the Food Guide for the Brazilian Population. The scoping review was conducted according to the JBI Manual for Evidence Synthesis via the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist and by searching PubMed/MEDLINE, EMBASE, SciELO and LILACS. Sixteen studies on relevant tools, based on the food guide for individuals of all age groups, were thus included: two descriptive studies, two randomized clinical trial protocols, eleven methodological analyses, and one psychometric paper, aimed at either a focal population (n=12) or health professionals (n=4). Six studies addressed tools for promoting adequate and healthy eating, and ten developed tools for evaluating dietary practices or the knowledge and activities of health professionals. This review can therefore assist health professionals in choosing instruments for the implementation and/or dissemination of food guide recommendations, contributing to the promotion of adequate and healthy eating habits.

Introduction

Adequate and healthy food is a basic human right¹1 Brasil. Emenda Constitucional nº 64, de 4 de fevereiro de 2010. Altera o art. 6º da Constituição Federal, para introduzir a alimentação como direito social. Diário Oficial da União; 2010. that involves the guarantee of permanent and regular access to an adequate dietary practice and must be in accordance with special dietary needs and the relevant culture, accessible, harmonious in quantity and quality, and based on sustainable production practices. The guideline for the Promotion of Adequate and Healthy Food (PAHF) is part of the National Food and Nutrition Policy and involves strategies such as food and nutrition education (FNE) and encouragement to create environments that promote adequate and healthy food to provide individuals and communities with appropriate dietary practices. This guideline is one of the priorities of the National Policy for Health Promotion, and for its implementation, the development of intersectoral actions in different spheres of government, together with society, must be articulated²2 Brasil. Ministério da Saúde (MS). Política Nacional de Alimentação e Nutrição (PNAN). Brasília: MS; 2013..

PAHF actions should support individuals in adopting healthy lifestyles, as well as identify and critically analyze unhealthy habits and practices. The set of these strategies contributes to the expansion of health actions, stimulating innovative alternatives that foster the development of individuals²2 Brasil. Ministério da Saúde (MS). Política Nacional de Alimentação e Nutrição (PNAN). Brasília: MS; 2013.. In this context, the Food Guide for the Brazilian Population (FGBP) constitutes one of the strategies for implementing PAHF guidelines³3 Brasil. Ministério da Saúde (MS). Guia Alimentar para a População Brasileira. Brasília: MS; 2014;.

The FGBP is an instrument for supporting and encouraging healthy eating practices and subsidizing the policies, programs, and actions for promoting the health and food and nutrition security (FNS) of the population. It is based on a broader concept of adequate and healthy eating, taking into account biological, sociocultural, and environmental aspects at the individual and collective levels. Its recommendations cover practices related to food choice, eating and commensality, in addition to highlighting possible obstacles to healthy eating practices, such as information, supply, cost, culinary skills, time or advertising³3 Brasil. Ministério da Saúde (MS). Guia Alimentar para a População Brasileira. Brasília: MS; 2014;^,44 Monteiro CA, Cannon G, Moubarac JC, Martins APB, Martins CA, Garzillo J, Canella DS, Baraldi LG, Barciotte M, Louzada ML da C, Levy RB, Claro RM, Jaime PC. Dietary guidelines to nourish humanity and the planet in the twenty-first century. A blueprint from Brazil. Public Health Nutr 2015; 18(13):2311-2322.. These recommendations are presented qualitatively, guided by the golden rule “always prefer natural or minimally processed foods and culinary preparations to ultra-processed foods”³3 Brasil. Ministério da Saúde (MS). Guia Alimentar para a População Brasileira. Brasília: MS; 2014;.

In fact, food-based dietary guidelines with qualitative recommendations facilitate the dissemination and understanding of information on adequate and healthy eating because they are simple, realistic and flexible⁴4 Monteiro CA, Cannon G, Moubarac JC, Martins APB, Martins CA, Garzillo J, Canella DS, Baraldi LG, Barciotte M, Louzada ML da C, Levy RB, Claro RM, Jaime PC. Dietary guidelines to nourish humanity and the planet in the twenty-first century. A blueprint from Brazil. Public Health Nutr 2015; 18(13):2311-2322.^,55 Oliveira MSS, Silva-Amparo L. Food-based dietary guidelines: a comparative analysis between the Dietary Guidelines for the Brazilian Population 2006 and 2014. Public Health Nutr 2018; 21(1):210-217.. However, during the implementation of these recommendations, challenges may occur, due to, e.g., the use of language and visual resources that are not very understandable by the population or the absence of educational materials, an effective validation of the recommendations, or a multidisciplinary team qualified to disseminate these recommendations⁶6 Gabe KT, Jaime PC. Development and testing of a scale to evaluate diet according to the recommendations of the Dietary Guidelines for the Brazilian Population. Public Health Nutr 2019; 22(5):785-796.^,77 Gabe KT, Jaime PC. Validade convergente e análise de invariância de uma escala de adesão a práticas alimentares recomendadas pelo Guia Alimentar para a População Brasileira. Rev Bras Epidemiol 2022; 25:e220009.. Such challenges hinder the adoption of adequate and healthy eating practices by the population⁸8 Food and Agriculture Organization of the United Nations (FAO). World Health Organization (WHO). Preparation and use of food-based dietary guidelines. Geneva: FAO/WHO; 1996;. Thus, the creation of tools that support and disseminate the recommendations in these dietary guidelines is essential for the adoption of these dietary practices in the daily life of the population⁸8 Food and Agriculture Organization of the United Nations (FAO). World Health Organization (WHO). Preparation and use of food-based dietary guidelines. Geneva: FAO/WHO; 1996;.

Therefore, to track and gather all the requisite tools for the evaluation and promotion of adequate and healthy eating produced by the FGBP, this scoping review was conducted to identify and discuss the salient literature regarding these tools.

Methods

Protocol and registration

This scoping review was conducted according to the JBI Manual for Evidence Synthesis⁹9 Aromataris E, Munn Z. JBI Manual for Evidence Synthesis [Internet]. JBI; 2020 [cited 2022 fev 12]. Available from: https://jbi-global-wiki.refined.site/space/MANUAL.

The PRISMA 2020 statement: an updated guideline for reporting systematic reviews. BMJ 2021; 372:n:71. and registered with the OSF (Registration DOI 10.17605/OSF. IO/TC7GD: https://archive.org/details/osf-registrations-tc7gd-v1). This analysis was guided by a main question: “What are the tools, based on the Food Guide for the Brazilian Population published in 2014, for the promotion and evaluation of adequate and healthy eating habits?”.

Eligibility criteria

Articles that have developed tools for the promotion and evaluation of adequate and healthy eating among individuals of all age groups, based on the FGBP, were included in thus review. Studies from any geographic setting were eligible for inclusion. Nonoriginal studies (comments, reviews, letters to the editor, case reports, theses, and abstracts) were excluded. Studies published before 2014 were also considered ineligible because the focal FGBP instrument was first published in 2014.

Search strategy

The search for original articles was performed using the following electronic bibliographic databases: PubMed/MEDLINE (www.pubmed.com), EMBASE (www.embase.com/landing?status=gray), Scielo (www.scielo.br) and Lilacs (www.lilacs.bvsalud.org).

The keywords were chosen from the Medical Subject Headings (MeSH) and Descriptors in Health Sciences (DeHS) using the search terms described in Chart 1.

The search strategy was not restricted by language. The last search was performed on March 28, 2022. A reverse manual search was also performed to identify the relevant articles cited in all selected studies.

Selection of studies

The authors (APA and PVMR) independently performed the study selection in three phases: analysis of titles, reading of abstracts, and reading and comprehension of full texts.

Any divergent decisions were resolved by consensus or, if necessary, by a third author (DMUPR). Duplicate articles in different databases were identified and excluded using Mendley®, and the peer review process was performed via Rayyan QCRY® Software, which ensured independent (blind) evaluation by the authors.

Data extraction

Two reviewers (APA and PVMR) extracted relevant information from the eligible studies, following an extraction table prepared by the researchers: (i) name of the first author, year of publication; (ii) study design; (iii) tool; (iv) target audience; (v) tool components; and (vi) evaluation of the psychometric properties (whether the study performed an evaluation of the psychometric properties validity and reliability and regarding the methods adopted for the evaluation) of the relevant tool. This information was extracted as presented in these studies; however, those that did not clearly explain any of the above parameters according to the information presented were classified by the authors as such. Any disagreements were resolved by a third author (DMUPR).

Data analysis

The data extracted from the selected studies are summarized in Charts 2 and 3 and separated by tools, based on the FGBP, for the promotion and evaluation of adequate and healthy eating. These studies are organized chronologically by year of publication, starting from the first published study.

Results

Selected studies

A total of 1,207 studies were identified after searching the PubMed, EMBASE, SciELO and LILACS databases. Notably, no articles were found in the reverse manual search. A total of 293 duplicate studies were removed, resulting in 914 unique records. After a complete reading of the abstracts, 46 studies were identified. Finally, after reading the full texts, 16 studies were selected because they met all the criteria adopted for this scoping review. The reasons for excluding the other studies are indicated in Figure 1.

Discussion

To the best of our knowledge, this is the first scoping review to identify, discuss and summarize the tools available for the promotion and evaluation of adequate and healthy eating habits based on the FGBP (2014) (Chart 5).

The importance of the Food-Based Dietary Guidelines for the adoption of healthy eating practices

Food-based dietary guidelines are tools for promoting healthy eating habits and lifestyles among the population of a country⁴4 Monteiro CA, Cannon G, Moubarac JC, Martins APB, Martins CA, Garzillo J, Canella DS, Baraldi LG, Barciotte M, Louzada ML da C, Levy RB, Claro RM, Jaime PC. Dietary guidelines to nourish humanity and the planet in the twenty-first century. A blueprint from Brazil. Public Health Nutr 2015; 18(13):2311-2322.^,2828 Bortolini GA, Moura ALP, Lima AMC, Moreira HOM, Medeiros O, Diefenthaler ICM, Oliveira ML. Guias alimentares: estratégia para redução do consumo de alimentos ultraprocessados e prevenção da obesidade. Rev Panam Salud Publica 2019; 43:1.^,2929 Oliveira MSS, Arceño MA, Sato PM, Scagliusi FB. Comparison of government recommendations for healthy eating habits in visual representations of food-based dietary guidelines in Latin America. Cad Saude Publica 2019; 35(12):e00177418.. According to the Food and Agriculture Organization of the United Nations (FAO), its Food Guidelines are intended to serve as a basis for the formulation of national policies on food and nutrition, health and agriculture, as well as for food and nutrition education programs for promoting healthy eating habits and lifestyles. They provide the general public with guidance on the foods, food groups and dietary patterns that provide essential nutrients for promoting general health and prevent chronic noncommunicable diseases (NCDs)³⁰30 Food and Agriculture Organization of the United Nations (FAO). Guías alimentarias basadas en alimentos [Internet]. 2022 [acessado 2022 dez 12]. Disponível em: https://www.fao.org/nutrition/educacion-nutricional/food-dietary-guidelines/home/es/.
https://www.fao.org/nutrition/educacion-... .

Dietary guidelines should be determined by public health issues and the sociocultural context (relevant social, economic, agricultural and environmental factors that affect food availability and dietary patterns) of each country; they should reflect dietary patterns rather than numerical targets, i.e., should be positive and encourage the pleasure of an adequate and healthy diet and based on evidence⁸8 Food and Agriculture Organization of the United Nations (FAO). World Health Organization (WHO). Preparation and use of food-based dietary guidelines. Geneva: FAO/WHO; 1996;.

In this context, in Brazil, the second version of the FGBP, published in 2014³3 Brasil. Ministério da Saúde (MS). Guia Alimentar para a População Brasileira. Brasília: MS; 2014;, plays a strategic role in encouraging public policies on food and nutrition and in guaranteeing the human right to adequate food and food sovereignty. With a qualitative approach guided by the degree of food processing and the sustainability of food systems, it consciously aims to ensure the health and nutrition of the Brazilian population and overcomes the idea of being a mere instrument for FNE actions⁴4 Monteiro CA, Cannon G, Moubarac JC, Martins APB, Martins CA, Garzillo J, Canella DS, Baraldi LG, Barciotte M, Louzada ML da C, Levy RB, Claro RM, Jaime PC. Dietary guidelines to nourish humanity and the planet in the twenty-first century. A blueprint from Brazil. Public Health Nutr 2015; 18(13):2311-2322.^,55 Oliveira MSS, Silva-Amparo L. Food-based dietary guidelines: a comparative analysis between the Dietary Guidelines for the Brazilian Population 2006 and 2014. Public Health Nutr 2018; 21(1):210-217.^,2828 Bortolini GA, Moura ALP, Lima AMC, Moreira HOM, Medeiros O, Diefenthaler ICM, Oliveira ML. Guias alimentares: estratégia para redução do consumo de alimentos ultraprocessados e prevenção da obesidade. Rev Panam Salud Publica 2019; 43:1..

The fact that there are dietary guidelines does not, however, guarantee an effective nutritional policy or that the population will follow these guidelines. In addition to these guidelines having a solid scientific basis, they must present a set of factors for the effective communication of information to the public. These guidelines should be practical, understandable, culturally accepted, multimedia, multisectoral, address all groups and ages, and complement existing community programs⁸8 Food and Agriculture Organization of the United Nations (FAO). World Health Organization (WHO). Preparation and use of food-based dietary guidelines. Geneva: FAO/WHO; 1996;^,3131 Smitasiri S, Uauy R. Beyond Recommendations: Implementing Food-Based Dietary Guidelines for Healthier Populations. Food Nutr Bull 2007; 28(Supl. 1):S141-S151..

Therefore, when the foods or food groups recommended in such guidelines are not accessible, widely available, and based on the food culture of the focal country, these dietary guidelines’ language and visual resources are not understandable; their design and implementation does not involve various sectors (nongovernmental organizations, the public sector or private companies) and professionals (educators, health professionals, social workers, extension workers, communication specialists, among others) in society; the professionals key to their dissemination lack the necessary education/training in and knowledge of their importance; there is no pilot testing or validation of the guidelines with nutritionists and their target audience; their recommendations are not effectively transformed into educational materials or disseminated across various media; and the time devoted to FNE activities is inefficient: All of these issues are obstacles that hinder an adequate implementation of the recommendations and dietary guidelines⁸8 Food and Agriculture Organization of the United Nations (FAO). World Health Organization (WHO). Preparation and use of food-based dietary guidelines. Geneva: FAO/WHO; 1996;.

In addition, the production and distribution of educational materials in various media (folders, booklets, videos, among others) and the training of professionals who disseminate the relevant recommendations are fundamental in the successful implementation of dietary guidelines and, consequently, the adoption of adequate and healthy eating habits by the population³²32 Gabe KT, Tramontt CR, Jaime PC. Implementation of food-based dietary guidelines: conceptual framework and analysis of the Brazilian case. Public Health Nutr 2021; 24(18):6521-6533.. Thus, the tools discussed in this article facilitate overcoming such obstacles and act as facilitators in the implementation of FGBP recommendations, rendering these messages more accessible to the Brazilian population while encouraging the adoption of an adequate and healthy diet.

Tools for the promotion of adequate and healthy eating based on the Food Guide for the Brazilian Population

In this review, three studies¹⁴14 Chagas CM, Pontes e Silva TB, Reffatti LM, Botelho RBA, Toral N. Rango Cards, a digital game designed to promote a healthy diet: a randomized study protocol. BMC Public Health 2018; 18(1):910.

Nutr J 2021; 20(1):10. developed tools based on mHealth to disseminate FGBP recommendations among the population. Khandpur et al.¹⁶16 Khandpur N, Quinta FP, Jaime PC. A quantitative test of the face validity of behavior-change messages based on the Brazilian Dietary Guidelines. Nutr J 2021; 20(1):10. developed 28 messages based on FGBP recommendations, sent through a digital platform. Melo et al.¹⁵15 Melo GR, Lima SC, Chagas CMS, Nakano EY, Toral N. Tailored smartphone intervention to promote healthy eating among Brazilian adolescents: a randomised controlled trial protocol. BMJ Open 2020; 10(10):e038896. used smartphones and WhatsApp messages for promoting healthy eating, and Chagas et al.¹⁴14 Chagas CM, Pontes e Silva TB, Reffatti LM, Botelho RBA, Toral N. Rango Cards, a digital game designed to promote a healthy diet: a randomized study protocol. BMC Public Health 2018; 18(1):910. developed a digital game (use on smartphones and tablets) to present this concept to the adolescent public. Therefore, the use of mHealth can be an important strategy for promoting adequate and healthy eating practices during the nutritional counseling process in different age groups.

Mobile health is a medical and public health practice supported by the use of cell phones, user monitoring devices, personal digital assistants and other wireless devices, which improve communication between health professionals and users and promote healthy lifestyles. Mobile health applications present a good opportunity for behavioral change interventions that require sustained adherence by keeping users engaged during health monitoring³³33 Dounavi K, Tsoumani O. Mobile Health Applications in Weight Management: A Systematic Literature Review. Am J Prev Med 2019; 56(6):894-903.

Nutrients 2022; 14(12):2437..

The FGBP focuses on concepts and information that need to be transmitted to the population in an objective, didactic way that promotes knowledge retention. In this sense, the tool developed by Geraldi et al.¹²12 Geraldi MV, Leite IQ, Pinto SN, Diez-Garcia RW. Pictorial instrument to guide the classification of foods in the dietary Guidelines for the Brazilian Population. Rev Nutr 2017; 30(1):137-144. can be used as supporting material in individual and group nutritional consultations on FNE, mediating and facilitating guidance on NOVA classifications through iconographic visual resources that support individuals in making adequate and healthy food choices with more autonomy. Among the strategies in the health area aimed at PAHF, the FNE is included. The development of personal skills in food and nutrition implies thinking of FNS as a process of dialog between health professionals and the population, which is of fundamental importance in the exercise of autonomy, self-care and empowerment regarding the adoption of adequate and healthy eating practices²2 Brasil. Ministério da Saúde (MS). Política Nacional de Alimentação e Nutrição (PNAN). Brasília: MS; 2013.^,3636 Brasil. Ministério do Desenvolvimento Social e Combate à Fome. Marco de referência de educação alimentar e nutricional para as políticas públicas. Brasília: Secretaria Nacional de Segurança Alimentar e Nutriciona; 2012.. The FNS represents a set of actions (problematic and active approaches and educational resources) that are essential in facilitating the voluntary adoption of healthy eating practices that lead to health promotion³⁶36 Brasil. Ministério do Desenvolvimento Social e Combate à Fome. Marco de referência de educação alimentar e nutricional para as políticas públicas. Brasília: Secretaria Nacional de Segurança Alimentar e Nutriciona; 2012.^,3737 Murimi MW, Kanyi M, Mupfudze T, Amin MR, Mbogori T, Aldubayan K. Factors Influencing Efficacy of Nutrition Education Interventions: A Systematic Review. J Nutr Educ Behav 2017; 49(2):142-165.e1..

In addition, Jaime et al.¹³13 Jaime PC, Tramontt CR, Maia TM, Gabe KT, Reis LC. Content validity of an educational workshop based on the Dietary Guidelines for the Brazilian Population. Rev Nutr 2018; 31(6):593-602. developed a protocol for a continuing education workshop for PHC professionals that promotes the implementation of GAPB recommendations among the population and, consequently, the adoption of adequate and healthy eating practices. Louzada et al.¹⁸18 Louzada MLC, Tramontt CR, Jesus JGL, Rauber F, Hochberg JRB, Santos TSS, Jaime PC. Developing a protocol based on the Brazilian Dietary Guidelines for individual dietary advice in the primary healthcare: theoretical and methodological bases. Fam Med Community Heal 2022; 10(1):e001276. developed a protocol for PHC professionals to apply the FGBP in individual dietary counseling. The creation of clinical guidelines may be an action for adapting professional practice and improving the quality and efficiency of care offered to users³⁸38 Graham R, Mancher M, Wolman DM, Greenfield S, Steinberg E, organizadores. Clinical Practice Guidelines We Can Trust. Washington, D.C.: National Academies Press; 2011.. Thus, the important role of health professionals in the successful implementation of the recommendations of the dietary guidelines among the population is highlighted. These professionals should be encouraged to acquire the basic information necessary to interpret the recommendations provided by dietary guidelines. For this, the education, qualification and training of these professionals can be planned to sensitize and educate them to fully understand the concepts and specific messages presented in the guidelines, whereby the actual implementation of the recommendations among the population occurs⁸8 Food and Agriculture Organization of the United Nations (FAO). World Health Organization (WHO). Preparation and use of food-based dietary guidelines. Geneva: FAO/WHO; 1996;.

Health education consists of the production and systematization of knowledge related to training and development in health care, involving teaching practices, didactic guidelines, and curricular guidance. One of the modalities of health education is continuing health education, which consists of the learning process occurring in professionals’ workspace, where learning and teaching are incorporated into daily life at organizations and during work³⁹39 Brasil. Ministério da Saúde (MS). Política Nacional de Educação Permanente em Saúde: o que se tem produzido para o seu fortalecimento? Brasília: MS; 2018..

Assessment tools for adequate and healthy eating based on the FGBP

The evaluation process is essential in verifying adherence to adequate and healthy eating practices, the extent to which the food environment promotes adequate and healthy eating, the acceptability and credibility of the salient recommendations, and what knowledge the population and health professionals should have acquired after the implementation of dietary guidelines and SAP tools. The results of an evaluation process can be used to modify or adjust these guidelines and tools, improving the impact and adherence of these recommendations among the population⁸8 Food and Agriculture Organization of the United Nations (FAO). World Health Organization (WHO). Preparation and use of food-based dietary guidelines. Geneva: FAO/WHO; 1996;^,4040 Andrade J, Andrande J. Technical Note: Methods for Teaching and Evaluating Food-Based Dietary Guidelines [Internet]. 2016 [cited 2022 nov 15]. Available from: http://ingenaes.illinois.edu/dp-tn/.
http://ingenaes.illinois.edu/dp-tn... . Given this context, tools such as the Diet Quality Index Adapted for Pregnant Women¹⁹19 Crivellenti LC, Zuccolotto DCC, Sartorelli DS. Development of a Diet Quality Index Adapted for Pregnant Women. Rev Saude Publica 2018; 52:59., a questionnaire for assessing knowledge of healthy eating habits and practices among children¹⁷17 Silva AB, Piccoli ÂB, Pellanda LC. Knowledge and food practices questionnaire: construction and validation. J Pediatr (Rio J) 2021; 97(2):177-183., the Culinary Skills Index²¹21 Martins CA, Baraldi LG, Scagliusi FB, Villar BS, Monteiro CA. Índice de Habilidades Culinárias: desenvolvimento e avaliação de confiabilidade. Rev Nutr 2019; 32:e180124., the Diet Quality Scale (SQUARE)²⁶26 Santos TSS, Araújo PHM, Andrade DF, Louzada MLC, Assis MAA, Slater B. Duas evidências de validade da ESQUADA e níveis de qualidade da dieta dos brasileiros. Rev Saude Publica 2021; 55:39., and the scale for measuring healthy eating practices⁶6 Gabe KT, Jaime PC. Development and testing of a scale to evaluate diet according to the recommendations of the Dietary Guidelines for the Brazilian Population. Public Health Nutr 2019; 22(5):785-796. are relevant for implementing and disseminating GAPB recommendations for adequate and healthy eating practices based on prior knowledge about the eating practices in a specific population.

In turn, the FGBP recognizes the role of the food environment in PAHF³3 Brasil. Ministério da Saúde (MS). Guia Alimentar para a População Brasileira. Brasília: MS; 2014;, defined as both the collective physical, economic, political and sociocultural space and the opportunities and conditions therein that influence the availability, access, selection, preparation and consumption of food and beverages, eating habits, the formation of eating habits, and nutritional status⁴¹41 Swinburn B, Sacks G, Vandevijvere S, Kumanyika S, Lobstein T, Neal B, Barquera S, Friel S, Hawkes C, Kelly B, L'Abbé M, Lee A, Ma J, Macmullan J, Mohan S, Monteiro C, Rayner M, Sanders D, Snowdon W, Walker C.

In this sense, the instrument for auditing the food environment (AUDITNOVA)²⁰20 Borges CA, Jaime PC. Development and evaluation of food environment audit instrument: AUDITNOVA. Rev Saude Publica 2019; 53:1-16. and its scoring system²³23 Borges CA, Gabe KT, Jaime PC. Consumer Food Environment Healthiness Score: Development, Validation, and Testing between Different Types of Food Retailers. Int J Environ Res Public Health 2021; 18(7):3690. make it possible to capture information such as availability, price, promotional and advertising strategy, number of brands available, and the healthiness of the consumer food environment by using, as a theoretical basis, the recommendations (NOVA classification) of the FGBP. In fact, this evaluation process is of fundamental importance because it can demonstrate the relationship between the consumer food environment and the development of CNCDs, thus supporting the creation of public policies that regulate the availability and advertising of food in these spaces²³23 Borges CA, Gabe KT, Jaime PC. Consumer Food Environment Healthiness Score: Development, Validation, and Testing between Different Types of Food Retailers. Int J Environ Res Public Health 2021; 18(7):3690..

According to the Preparation and use of food-based dietary guidelines⁸8 Food and Agriculture Organization of the United Nations (FAO). World Health Organization (WHO). Preparation and use of food-based dietary guidelines. Geneva: FAO/WHO; 1996;, for the implementation of dietary guidelines to be successful, the professionals who act as the promoters of their recommendations need to have adequate knowledge of the information contained therein to optimally disseminate this information to the population. Thus, the evaluation of this knowledge among professionals²⁴24 Reis LC, Jaime PC. Pool of items to measure Primary Health Care workers' knowledge on healthy eating. Rev Saude Publica 2021; 55:55., of the ability of health professionals to promote dietary advice²⁵25 Reis L, Jaime P. Measuring professional self and collective efficacy for dietary advice in Primary Health Care. Nutr Health 2021; 27(1):49-57., and of the FNE practices applied by these professionals²²22 Reis LC, Jaime PC. Scale for evaluating food and nutrition education practices in Primary Health Care. Rev Nutr 2020; 33:e190231. in promoting FGBP recommendations are fundamental for obtaining knowledge of the gaps and points that need improvement in food and nutrition guidance. Accordingly, mechanisms can be created to train health professionals, enabling the propagation of FGBP recommendations more efficiently and, consequently, achieving more success in PAHF among the population.

Evaluation of the psychometric properties of the tools

For a tool to be used in research or professional practice, its psychometric properties, that is, its reliability and validity, must be evaluated and considered appropriate. Reliability, one of the main quality criteria of an instrument, is the ability to reproduce a consistent result across time, space and different observers, demonstrating the aspects of stability (degree to which similar results are obtained at two different times), internal consistency (indicates whether the domains of an instrument measure the same characteristic) and equivalence (degree of agreement between two or more observers regarding the scores of an instrument)⁴⁴44 Souza AC, Alexandre NMC, Guirardello EB. Propriedades psicométricas na avaliação de instrumentos: avaliação da confiabilidade e da validade. Rev Epidemiol Serv Saude 2017; 26(3):649-659.

Int J Med Educ 2022; 13:100-106..

Validity, on the other hand, entails that an instrument measures exactly what it purports to measure, i.e., it is based on the degree to which the content thereof adequately reflects the construct being measured (content validity). The degree to which a group of variables represents the construct to be measured (construct validity) and the degree to which the instrument is related to some external criterion are widely accepted measures (criterion validity)⁴⁴44 Souza AC, Alexandre NMC, Guirardello EB.

Notably, these tools must be accurate, valid and interpretable to allow their application in the population. Thus, when these studies present, in their methodologies, quality evaluations, either by validity or reliability, these help professionals to reliably and validly determine the most appropriate tool to be applied in professional practice according to the circumstances, population, type and purpose of each PAHF action⁴⁴44 Souza AC, Alexandre NMC, Guirardello EB.

Strengths and limitations

The articles included in this scoping review have observable strengths, such as their objective tools that are easily applied and used in professional routines to evaluate dietary practices, the consumer food environment, professional practices, and SAPS. However, these articles also have some limitations, such as a lack of standardization among the studies assessing psychometric properties and a divergence in the methodologies applied in the evaluation of reliability and validation. Moreover, not all the articles evaluated the reliability and validity of the focal tools. In addition, few studies developed nonvirtual tools or tools that do not depend on resources such as the internet, computers and cell phones for their application in professional practice. Finally, the development of more studies that address the creation of tools for the qualification of health professionals working in PHC is still necessary.

Conclusion

The present review has identified tools for the promotion and evaluation of adequate and healthy eating, their applicability, and the audience for which each of them is intended. These tools are essential for the implementation and dissemination of the recommendations proposed by the FGBP. This review can therefore assist health professionals in choosing the most appropriate instrument for the promotion and evaluation of healthy eating practices, thereby improving the actions for promoting healthy eating in health settings.
