ABSTRACT

OBJECTIVE

Identify the perception operating agents have on the Brazilian National School Feeding Program.

METHODS

This is an observational, cross-sectional and quali-quantitative study developed in non-probability and convenience sampling selected in an event promoted by the National Fund for Educational Development in 2015 in Rio de Janeiro. Data were collected through questions related to pre-defined categories concerning the National School Feeding Program. The questionnaire was answered by 43 nutritionists, 41 members of the School Feeding Board, and 16 school feeding administrators from 38 cities of Rio de Janeiro. The narrative analysis was based on benchmarks of cognitive analysis of public policies. The association among variables was investigated with chi-square test, being calculated the power for association testing.

RESULTS

The perception of the implementation of the National School Feeding Program has been characterized by some challenges: 1) low number of nutritionists to meet the demand from schools; 2) low adhesion to the public call for the purchase of family farming products due to bureaucratic difficulties and insufficient local food production; 3) reduced coverage of food and nutritional measures due to the restriction of human, material and financial resources; and 4) limitation of the participation of the School Feeding Board due to insufficient training and transport for regular visits. The adequacy of the number of nutritionists showed statistically significant association with the purchase of family farming products (p = 0.002; power = 99%) and with the food and nutritional education activities (p = 0.021; power = 79%).

CONCLUSIONS

The results indicate the need for employment of nutritionist in sufficient numbers to meet the demands of the National School Feeding Program, investment in educational activities of healthy eating in schools, training of the School Feeding Board, greater availability of vehicles for school visits and assistance to family farmers in order to facilitate their participation in programs of institutional purchases and encourage the diversification of production.

INTRODUCTION

The National School Feeding Program (PNAE) is one of the largest and oldest programs in the world and, in Brazil, is part of the Food and Nutrition Security Policy ¹1. Peixinho AML. A trajetória do Programa Nacional de Alimentação Escolar no período de 2003-2010: relato do gestor nacional. Cienc Saude Coletiva. 2013;18(4):909-16. https://doi.org/ 10.1590/S1413-81232013000400002
https://doi.org/ 10.1590/S1413-812320130... . Its main objectives are related to the provision of meals that ensure nutritional needs during the stay of the students in the school and the formation of healthy food habits ²2.

http://www.fnde.gov.br/arquivos/category... . Since its implementation in 1955, the legal devices governing the program have presented technical and operational advances through reviews and upgrade^3–5 aiming to guarantee the human right to an adequate diet (DHAA). These changes involve the inclusion of a nutritionist as a responsible technician (RT), the social control of the implementation of the program by the School Feeding Board (CAE) and the purchase of family farming products, with an investment of at least 30% of the financial allocation made by the National Fund for Educational Development (FNDE) ³3.

Considering PNAE is one of the most important health promotion programs in the country, a fact evidenced by its contribution to the formation of healthy eating habits of students from primary public education ⁵5. Ministério da Educação (BR), Fundo Nacional da Educação. Resolução/CD/FNDE No26, de 17 de junho de 2013.

Diario Oficial Uniao. 18 jun 2013; p. 1-44. , it is essential that its principles and guidelines are implemented fully by the agents involved. However, several Brazilian cities have problems with its execution, such as the low percentage of purchases of family farming foodstuffs ⁷7. Gabriel CG, Costa LCF, Calvo MCM, Vasconcelos FAG.

https://doi.og/10.1590/1415-527320150002... , and the insufficient number of nutritionists ¹²12. Chaves LG, Santana TCM, Gabriel CG, Vasconcelos FAG.

https://doi.og/10.1590/S1413-81232013000... .

Such limitations should be better understood to facilitate the proposition of strategies that contribute to overcoming the challenges. However, few studies explore the context in which the measures envisaged by the program are developed, expressing the origin of these obstacles superficially. Thus, this study aimed to identify the perception operating agents of PNAE have about the fulfilment of its primary legal parameters.

METHODS

Ethical Aspects

The study is in line with the Resolution 466 of December 12, 2012. This study was approved by the Research Ethics Committee of the Universidade Federal Fluminense (CAAE 3620.0.000.258-10).

All the participants signed an informed consent form after being informed of the procedures in this study. The questions were answered in writing without personal identification or the city. Only the participant’s position was identified for data analysis.

Design and Sample

This is a descriptive and observational cross-sectional study with a quali-quantitative approach developed in a non-probability and convenience sampling. The operating agents of PNAE present at the event “Technical Meeting of the National School Feeding Program” ^aaEncontro Técnico do Programa Nacional de Alimentação Escolar, 23 set 2015; Niterói, RJ [cited 2019 Feb 1]. Available from: http://www.uff.br/?q=events/i-encontro-tecnico-do-programa-nacional-de-alimentacao-escolar , promoted by FNDE in 2015 in the metropolitan region of Rio de Janeiro, were invited to participate.

The sample size calculation was carried out with the pwr Pack of the R program version 3.4.3 (R Core Team, Austria). Considering the factors and respective levels of the semi-structured questionnaire, the power of test of 80%, and the significance level of 5%, 85 participants are needed (4x3: 6 degrees of freedom) to observe a medium to large effect size (w = 0.4).

A total of 189 operating agents of PNAE from 58 cities participated in the event, being excluded those living outside the state of Rio de Janeiro (n = 5). One hundred individuals agreed to participate in the research, including nutritionists (n = 43), members of CAE (n = 41) and school feeding administrators of (n = 16) from 38 (41.3%) of the 92 cities of the state of Rio de Janeiro. Among the cities represented in this study, 33 (86.8%) are predominantly urban, while 5 cities (13.2%) are rural ¹³13. Instituto Brasileiro de Geografia e Estaítstica, Diretoria de Geociências, Coordenação de Geografia. Classificação e caracterização dos espaços rurais e urbanos do Brasil: uma primeira aproximação. Rio de Janeiro: IBGE; 2017 [cited 2017 Feb 18]. (Estudos e Pesquisas. Informação Geográfica; 11). Available from: https://biblioteca.ibge.gov.br/visualizacao/livros/liv100643.pdf
https://biblioteca.ibge.gov.br/visualiza... . The distribution of agents by city comprehended: one city with nine agents, two cities with six agents, one city with five agents, four cities with four agents, 11 cities with three agents, six cities with two agents, and 13 cities with only one agent.

Procedures

The information was collected through a semi-structured questionnaire created by the researchers based on the categories of analysis predefined in this study. The questions addressed the following items related to the implementation of PNAE in the cities of Rio de Janeiro: adequacy of the number of nutritionists in the program; percentage of purchase and foodstuffs from family farming; main difficulties found in the implementation of PNAE; development of educational activities to promote a healthy eating habit at schools; and the activity of CAE in the city.

Qualitative Data Analysis

We used a contents and narrative analysis ¹⁴14. Bardin L. Análise de conteúdo. São Paulo: Edições 70; 2011. as a tool to identify the main ideas and perceptions the subjects have about the operationalization of PNAE in the cities studied. To this end, the following steps were followed:

1. Pre-exploration of the material: skimming of all the answers contained in the questionnaire to seize and organize in a non-systematized way the main ideas and perceptions that provided initial evidence for a more systematized presentation of the data in the following steps;

2. Ex ante categorization: use of predefined categories based on the implementation of PNAE: role of nutritionists; purchase of family farming products; activity of CAE in the city; food and nutritional education measures; several difficulties in implementing the PNAE.

3. Selection of subcategories of analysis: guided by the questions, corresponding to items related to the implementation of PNAE. The subcategories of analysis were identified from text clippings by an inductive process, considering the explicit message and the non-apparent meanings of the context. The grouping of units of analysis is based on the repetition of contents common to most respondents and on the implicit relevance, when the topic was considered important for the study, but it was not repeated by the respondents.

This whole process was conducted along with the researchers to avoid perceived bias and to provide a different view of the categories proposed.

The narrative analysis was based on the perception of the subjects participating in the operationalization of PNAE in cities of the state of Rio de Janeiro. Thus, the program was considered a social practice ¹⁵15. Potvin, L. On the nature of programs: health promotion programs as action.

Statistical Analysis

Data were tabulated in contingency tables and analyzed in the statistical program SPSS version 21 (IBM, USA). The variables were described by absolute and relative frequency (n, %). The association between the categorical variables was investigated through the chi-square test (χ²). For 2 x 2 tables, the Fisher’s exact test was used. The power of test (1-β) was calculated with the R program version 3.4.3 (R Core Team, Austria) and the pwr pack. A significance level (α) of 5% was adopted.

RESULTS

The Box presents qualitative synthesis of the perception operating agents of PNAE have about the key challenges faced in the implementation of the program in their cities. A priori , five categories were defined related to the main items of PNAE. A posteriori , fourteen subcategories were identified by reflecting the difficulties expressed in the contents reported. The following categories and subcategories include: role of nutritionists (assignments, quantitative adequacy, workload and employment), purchase of family farming products (acquisition of aptitude certificate for the National Program for Strengthening Family Farming, local production and foodstuffs purchased), activity of CAE in the city (transport, training of members and participation), food and nutritional education measures (insufficient number of nutritionists, breadth of educational measures and financial resources), and difficulties in implementing the PNAE (financial allocation and excessive administrative work for the nutritionist).

Table 1 shows data on the implementation of the items proposed by PNAE according to the reports of operating agents. Most nutritionists (n = 39; 90.7%) and members of CAE (n = 34; 75.6%) consider the number of professionals insufficient to perform all the activities assigned by PNAE (p = 0.008; power = 80%). This opinion is related to the high demand of school units with a large number of students ( Box, item A1 ), hindering the assistance and implementation of monitoring tasks of the nutritional status of students and development of projects to promote healthy eating and nutritional education activities. The overload and the urgency of bureaucratic and administrative tasks were also cited as a barrier to the implementation of technical assignments ( Box, item E2 ).

The purchase of family farming products over 30% of the resources provided by FNDE was reported by 70.1% (n = 47) of respondents, while the purchase of organics had a frequency of 12.5% (n = 11). However, these variables did not show statistically significant association with the operating agents of PNAE (p > 0.05). Foods commonly purchased from family farming come in natura form, such as lettuce, tomatoes, cassava, yams, parsley and chives, cabbage, pumpkin, wild cabbage, banana, orange, pineapple, sweet potato, carrot, beet, persimmon, okra, eggs, honey, and milk. Analyzing the answers per city, 55.3% (n = 21) were buying over 30%, while 10.5% (n = 4) had not acquired foodstuffs yet for being in a public call process. The main justification presented for the purchase of family farming products was the enforcement of legislation. Although they met the requirement, 21.0% (n = 8) of cities reported difficulties due to the lack of the aptitude certificate for the National Program for Strengthening Family Farming (PRONAF) by farmers ( Box, item B1 ) and for the lack of local food production (Table, item B2).

The existence of educational activities to promote healthy eating habits in schools was reported by 83.7% (n = 82) of the respondents. Training through workshops with the lunch ladies were the main activities carried out ( Box, item D2 ). In a lower frequency, group dynamics with students and lectures with the parents promoted by nutritionists, teachers and educators were also included in nutritional education. However, the frequency of these activities was not mentioned. Among the main criteria established as gridlock for the implementation of educational activities are the difficulties with human resources, due to the insufficient number of nutritionists and other professionals ( Box, item D1 ), and the availability of financial and material resources to develop workshops routinely (Table, item D3).

Most respondents (n = 66; 67.3%) classified the activity of CAE in the cities as good and significant (p = 0.009; power = 86%); the members of the board (n = 36; 80%) classified their own work as good. One of the measures developed includes technical visits and supervision of schools, participation in meetings, conversations with students about the acceptance of menus and monitoring of the implementation of PNAE resources. Regular and bad qualifications were mostly attributed to the lack of training for board members and transport for regular visits ( Box, items C2 and C1, respectively ).

Table 2 shows the statistically significant association of quantitative adequacy of nutritionists in PNAE with the purchase of family farming products (p = 0.002; power = 99%) and with the food and nutritional education activities (EAN) (p = 0.021; power = 79%), indicating that the cities struggling to fulfill the legislation parameters are those with insufficient number of nutritionists, according to the participants. The opinion about the quality of the activity of CAE did not show statistically significant association with the purchase of organic foods (p = 0.729; power = 10%) and family farming (p = 0.273; power = 28%), nor with the activities of EAN (p = 0.905; power = 7%).

Isolating the quantitative answers of the operating agents of PNAE from the same city (25 cities with more than one agent), few showed differences among themselves. Regarding the adequacy of the number of nutritionists and purchase of organic foods, only 8% (n = 2) of the cities presented divergent answers. As to the purchase from family farming, 16% (n = 4) of cities showed disagreement. The questions with more differences were those related to the implementation of activities of EAN (n = 6; 26% of cities) and CAE (n = 5; 20.8% of cities). This observation is important to identify whether the answers reflect the reality of each city.

DISCUSSION

The integrated narrative analysis, based on different segments of subjects who participate directly in the operationalization of PNAE in the cities, indicates as the main strategic questions for the quality of the program aspects related to the institutional structure, the articulation with family farmers, the financial contribution, and social participation.

About the role of nutritionists, almost all of them reported an insufficient number of professionals, which is a possible limitation for the fulfilment of the tasks established in the program, generating workload. The optimal number of nutritionists to participate in the program is referenced in the Resolution 26/2013 of FNDE5 ⁵5. Ministério da Educação (BR), Fundo Nacional da Educação. Resolução/CD/FNDE No26, de 17 de junho de 2013. Dispõe sobre o atendimento da alimentação escolar aos alunos da educação básica no âmbito do Programa Nacional de Alimentação Escolar – PNAE. Diario Oficial Uniao. 18 jun 2013; p. 1-44. , which follows the numeric parameters for employment of professionals by execution unit of PNAE established in Resolution 465/2010 of the Federal Council of Nutritionists (CFN) ⁴4. Conselho Federal de Nutricionistas. Resolução CFN no465/2010. Dispõe sobre as atribuições do Nutricionista, estabelece parâmetros numéricos mínimos de referência no âmbito do Programa de Alimentação Escolar (PAE) e dá outras providências. Diario Oficial Uniao. 25 ago 2010; p. 1–8. . According to this resolution, all execution entity must have a nutrition technician responsible for the program, regardless of the number of students. Above 501 students, there must also be a nutritionist within the technical framework (TF), increasing the number of nutritionists as the number of students rise. Reports of the existence of one nutritionist for each 5,000 students were observed, scenario where there should be a nutritionist RT and three nutritionists of TF ⁴4. Conselho Federal de Nutricionistas. Resolução CFN no465/2010. Dispõe sobre as atribuições do Nutricionista, estabelece parâmetros numéricos mínimos de referência no âmbito do Programa de Alimentação Escolar (PAE) e dá outras providências. Diario Oficial Uniao. 25 ago 2010; p. 1–8. .

Two other important matters mentioned by nutritionists are the weekly workload of 20 hours and the difference of employment relationship among professionals, which contributes to the reduction of autonomy and turnover of those working under CLT regime. Given this scenario, the monitoring and implementation of the PNAE guidelines are compromised, hindering the control of the nutritional status of students, food and nutrition education activities and the supervision of the entire production process of meals, since the acquisition of food until the distribution in order to meet the principles of food and nutrition security and ensure hygienic sanitary conditions ¹¹11.

As to the participation of family farming in school meals, the minimum percentage of acquisition became mandatory as of January 2010 ³3. Brasil. Lei no 11.947, de 16 de junho de 2009. Dispõe sobre o atendimento da alimentação escolar e do Programa Dinheiro Direto na Escola aos alunos da educação básica..., e dá outras providências. Diario Oficial Uniao. 17 jun 2009; p. 11. , favoring the sustainability, reduction of rural exodus and increase in job offers with local development ⁶6. Saraiva EB, Silva APF, Sousa AA, Cerqueira GF, Chagas CMS, Toral N. Panorama da compra de alimentos da agricultura familiar para o Programa Nacional de Alimentação Escolar. Cienc Saude Coletiva. 2013;18(4):927-35. https://doi.og/10.1590/S1413-81232013000400004
https://doi.og/10.1590/S1413-81232013000... . In this study, most cities (55.3%) reported the purchase of family farming products over 30% of federal financial resources. However, this percentage was lower than that found by Ferigollo et al. ¹⁸18. Ferigollo D, Kirsten VR, Heckler D, Figueiredo OAT, Perez-Cassarino J, Triches RM. Aquisição de produtos da agricultura familiar para alimentação escolar em municípios do Rio Grande do Sul. Rev Saude Publica. 2017;51(6):1-10. https://doi.og/10.1590/S1518-8787.2017051006648
https://doi.og/10.1590/S1518-8787.201705... (71.2%) in a study carried out in the cities of Rio Grande do Sul. According to Saraiva et al. ⁶6. Saraiva EB, Silva APF, Sousa AA, Cerqueira GF, Chagas CMS, Toral N. Panorama da compra de alimentos da agricultura familiar para o Programa Nacional de Alimentação Escolar. Cienc Saude Coletiva. 2013;18(4):927-35. https://doi.og/10.1590/S1413-81232013000400004
https://doi.og/10.1590/S1413-81232013000... , the South stands out in the production of family farming and the internal supply of food, which can justify its successful experience. Some cities of Rio de Janeiro still face difficulties, which, according to the reports, refer mainly to the lack of the PRONAF (DAP) aptitude certificate to compete for the public call process and the insufficient local production to meet the demand of school meals. The DAP is used to identify and qualify the family units of agrarian production and to give access to PRONAF credit lines and other public purchase policies of the federal government, such as the Food Acquisition Program (PAA) and the PNAE. According to the operating agents of PNAE, the main obstacle is related to bureaucratic issues, such as the existence of farmers who do not declare or declare a reduced portion of sales through invoices, hindering the proof of agricultural income required for the issuance of DAF.

Another difficulty reported about the purchase of family farming products is linked to the lack of compliance with the demand for school meals to local production. Some cities, especially those with more urban-rural characteristics, present insufficient production in quantity and variety of foodstuffs. Although the legislation allows the purchase from farmers in neighboring cities, some reports showed that they are not interested in selling due to the logistics of foodstuff transportation to schools. Saraiva et al. ⁶6. Saraiva EB, Silva APF, Sousa AA, Cerqueira GF, Chagas CMS, Toral N. Panorama da compra de alimentos da agricultura familiar para o Programa Nacional de Alimentação Escolar. Cienc Saude Coletiva. 2013;18(4):927-35. https://doi.og/10.1590/S1413-81232013000400004
https://doi.og/10.1590/S1413-81232013000... , in a study on the subject in the five Brazilian regions, attributed the non-compliance with the legislation to the lack of proper planning of menus and to the inadequate estimate of the demand of food needed, stressing the importance of integrating buyers and farmers. Articulations are needed between farmers and school feeding administrators, being implemented in the form of technical and logistical support to facilitate the integration of producers into the markets and the access to the public call ¹⁹19. Bezerra OMPA, Bonomo E, Silva CAM, Correa MS, Souza AA, Santos PCT, et al. Promoção da aquisição de produtos da agricultura familiar para a alimentação escolar em Territórios da Correa MS, Cidadania de Minas Gerais e Espírito Santo. Rev Nutr. 2013;26(3):335-42. https://doi.og/10.1590/S1415-52732013000300008
https://doi.og/10.1590/S1415-52732013000... . In this study, we observed that the insufficient number of nutritionists in the program, according to the participants, was associated with an insufficient percentage of purchases. Thus, the adequacy of the number of these professionals is an important factor for the development of menus suitable for the local culture, for the strengthening of the relationship with family farming and, finally, for the enforcement of the legislation.

In a study carried out in cities of the southern region and published in 2015 ⁹9. Gabriel CG, Goulart G, Calvo MCM. Gestão municipal do Programa Nacional de Alimentação Escolar nas capitais da região Sul do Brasil. Rev Nutr. 2015;28(6):667-80. https://doi.og/10.1590/1415-52732015000600009
https://doi.og/10.1590/1415-527320150006... , we observed support for the participation of the small farmer in PNAE. However, only one of the three cities assessed reached the minimum of 30%. The success of the participation of family farming in PNAE goes beyond the support for the farmer, requiring the valuation and adequate training of the nutritionist working in this process. The approach of topics that go beyond the health field, such as school feeding and food and nutrition security, which cover issues related to the production, supply, marketing, access, and food consumption, occupy an incipient position in the curriculum of nutrition courses in public and private higher education institutions in the country ²⁰20.

https://doi.og/10.1590/S1413-81232013000... stressed the need to insert this purchasing process in various governmental and public policies and highlight as a key factor the planning of strategies capable to address these challenges. Among the strategies, the authors describe the adequacy of institutional structures as fundamental and indicate as examples the technical advisory for farmers, adequacy of logistics and storage infrastructure, diagnosis of the local agricultural reality and the creation of spaces for discussion and planning with farmers, public administrators, and schools.

Diario Oficial Uniao. 18 jun 2013; p. 1-44. , the purchase of organic foods must be a priority in PNAE. The low percentage reported on the acquisition of organic foods was not related to the number of nutritionists of the program, which may be due to the difficulty in establishing a partnership with unions of producers of organic foods and planning or to the search for the best price, because its cost superior to that of conventional foods hinders the inclusion in school menus. However, according to the current legislation, organic or agroecological products can be purchased for up to a value 30% higher compared with the prices established for conventional products ⁵5.

The Organic School Feeding Program, from Santa Catarina, receives financial resources from the state ²¹21. Lima EE, Sousa AA.

https://doi.og/10.1590/S1415-52732013000... , studying the offer and demand for organic food for school meals, observed that in 2010 only 17.7% of the cities in Santa Catarina purchased this type of food. A total of 42% of the nutritionists reported having difficulties in the acquisition and use of organic foods in PNAE, such as: lack of products on the market, resistance of lunch ladies due to the foods’ appearance, prices and lack of organic certification.

Regarding the social control of the program, the study showed that some cities lack visits from the CAE to the schools, claiming lack of transport. Other difficulties reported refer to the lack of training for its members and adhesion to the activities assigned by the legal devices. According to legislation ⁵5. Ministério da Educação (BR), Fundo Nacional da Educação. Resolução/CD/FNDE No26, de 17 de junho de 2013. Dispõe sobre o atendimento da alimentação escolar aos alunos da educação básica no âmbito do Programa Nacional de Alimentação Escolar – PNAE. Diario Oficial Uniao. 18 jun 2013; p. 1-44. , the EE must offer the necessary infrastructure for the transport of the members of the board, and the failure to comply with this obligation impairs the monitoring of the guidelines of the program. Similar results were found by Souza ²³23. Souza AA. Atuação de conselheiros de alimentação escolar e nutricionistas responsáveis técnicos pelo Programa Nacional de Alimentação Escolar segundo suas atribuições legais: estudo em municípios de Minas Gerais e Espírito Santo, 2009-2013 [dissertation]. Ouro Preto: Escola de Nutrição da Universidade Federal de Ouro Preto; 2015. , who observed a malfunction of CAE in the cities of Minas Gerais and Espírito Santo, highlighting the inadequate working conditions of advisers and the ignorance of the guidelines and regiments of the program. To promote training spaces for members of the board is a way of strengthening its role as a supervisory body and the appropriate application of financial resources on school meals.

In this study, the participants classify the activity of CAE in the cities between good and regular, a perception that is not significantly associated with purchases of family farming products and organic food, nor with carrying out activities of EAN. It is important to consider that this is the perception of the participants and not an assessment or analysis of the role of the entity. Some studies have found that, in cities where CAE held about 20 meetings a year, there was the hindrance of school feeding outsourcing and closer monitoring of the development and acceptance of the menus by students ¹⁰10.

https://doi.og/10.1590/S1415-52732012000... and on the support for healthy eating.

Among the PNAE guidelines, the need for inserting food and nutritional education in the teaching-learning process has gained prominence. For the development of healthy eating habits, it is not enough to offer a menu; educational measures are also needed for a better understanding of the students, who are going through the cognitive development process ²⁵25. Ministério da Educação (BR), Fundo Nacional de Desenvolvimento da Educação, Conselho Deliberativo. Resolução/FNDE/CD No32 de 10 de agosto de 2006. Estabelece as normas para a execução do Programa Nacional de Alimentação Escolar-PNAE. Diario Oficial Uniao. 11 ago 2006; p. 32. . Such curricular insertion has been developed through topics related to food and nutrition security, comprising food, nutrition, and practices for healthy living ³3. Brasil. Lei no 11.947, de 16 de junho de 2009. Dispõe sobre o atendimento da alimentação escolar e do Programa Dinheiro Direto na Escola aos alunos da educação básica..., e dá outras providências. Diario Oficial Uniao. 17 jun 2009; p. 11. . We highlight the importance of EAN, from the food and nutrition security approach, in the expansion of the senses assigned to healthy eating in a perspective of DHAA among the school agents ²⁶26. Barbosa NVS, Machado NMV, Soares MCV, Pinto ARR. Alimentação na escola e autonomia: desafios e possibilidades. Cienc Saude Coletiva. 2013;18(4):937-45. https://doi.og/10.1590/S1413-81232013000400005
https://doi.og/10.1590/S1413-81232013000... .

According to FNDE, EAN is regarded as “the set of formative measures, of continuous, permanent, transdisciplinary, multidisciplinary, intersectoral, and multi-professional practice, aiming to encourage the voluntary adoption of healthy practices and better food choices that collaborate to a learning experience, to the student’s health state and to the individual’s quality of life” ²⁷27. Ministério da Educação (BR), Fundo Nacional de Desenvolvimento da Educação. Ações educativas. Brasília, DF: FNDE; 2017 [cited 2017 Aug 15]. Available from: http://www.fnde.gov.br/acessibilidade/item/4119-ações-educativas
http://www.fnde.gov.br/acessibilidade/it... . The study showed scarce food and nutrition educational activities with the school community as a whole, and the most affected cities were those with insufficient nutritionists, according to the participants. The absence of the theme in the education network does not contribute to the effectiveness of PNAE, as the practice must be combined with the theory for a significant construction of knowledge about healthy eating.

Considering the large number of schools for each nutritionist in EAN, we suggest investing in the training of agents of the school community who are involved with the program, such as teachers, food handlers, principals and parents, in order to share experiences in food and nutrition and contribute to building a healthy eating environment. Gabriel et al. ⁹9. Gabriel CG, Goulart G, Calvo MCM. Gestão municipal do Programa Nacional de Alimentação Escolar nas capitais da região Sul do Brasil. Rev Nutr. 2015;28(6):667-80. https://doi.og/10.1590/1415-52732015000600009
https://doi.og/10.1590/1415-527320150006... , in a study that assessed the municipal management of PNAE in the three capitals of the south region of Brazil, noted the absence of pedagogical activities in most of the cities studied. Only one capital carried out food and nutrition education projects involving all municipal education network. One of the capitals provided training in EAN with some teachers, but not implemented the training evaluation methodology. Two capitals inserted healthy nutrition into the school curriculum, but that insertion was considered incipient.

Despite the activity of EAN being mandatory and the role of the nutritionist in PNAE ²2. Ministério da Educação (BR), Fundo Nacional de Desenvolvimento da Educação.

https://doi.og/10.1590/S1415-52732012000... , in a study conducted in northeastern cities, noted that only 33% of the nutritionists interviewed performed them with frequency. The lack of stimulus, low salaries, and devaluation of the professional were indicated as possible factors for this low frequency. Voos and Schuch ²⁸28. Voos AC, Schuch I. Atuação do nutricionista no Programa Nacional de Alimentação Escolar (PNAE) no Estado do Rio Grande do Sul. Porto Alegre: Universidade Federal do Rio Grande do Sul; 2009. Monografia para o Curso de Especialização em Saúde Pública , studying the role of the nutritionist in PNAE in the state of Rio Grande do Sul, observed that the main reasons reported for not performing these activities were the low number of nutritionists to meet the demand and the lack of support and interest of the authorities of the city to solve the problem.

The results of this study should be interpreted considering its advantages and limitations. First, the participation of different operating agents of PNAE (nutritionists, administrators and members of CAE) of approximately 40% of the cities in the state suggests a moderate representation of Rio de Janeiro. The inclusion of other cities can contribute to socially different perceptions and should be considered in future studies. Second, the perception operating agents have about the implementation of PNAE was investigated so reality could be portrayed and interpreted in accordance with the position the professional occupies in the organizational structure of the program. Although perception and implementation may differ, the perception that the program is not contemplated in any way justifies a reflection upon its execution. The identification of perceptions in this study reveals the challenges faced in the implementation of PNAE, resulting in the construction of new perspectives to be directed to the solution of problems.

CONCLUSIONS

The perceptions of operating agents were based on the role of the nutritionist in the program, on the purchase of family farming products and organics, on the activities of EAN and CAE as a mechanism of social control. The insufficient number of nutritionists and the inadequate employment relationship were considered limiting factors for the accomplishment of all the tasks assigned to the professional. The insufficient number of nutritionists who work in the program showed significant association with the reduced percentage of purchase of family farming products and EAN activity in the school environment. The activities, in turn, were scarce when directed to the promotion of healthy eating habits with the school community. Although most respondents classified the activity of CAE as good, the lack of training courses for advisers, the lack of transport for school visits and the lack of engagement of all members in the execution of their duties in the board are some of the current difficulties.

Thus, based on the main difficulties experienced by operating agents of the program, we suggest as strategic measures for the strengthening of PNAE: (1) employment of nutritionists in sufficient numbers to meet the demands of PNAE, (2) investment in educational activities to promote healthy eating habits in the school environment, (3) training of members of CAE and availability of vehicles for school visits and (4) technical support, within the municipal management framework, for organic and family farmers, in order to facilitate the organization and participation in programs of institutional purchases and encourage the diversification of production.
