INTRODUCTION

In Brazil, food and nutrition surveillance is a strategy adopted within the scope of the Brazilian National Health System (Sistema Único de Saúde - SUS) to monitor and evaluate the nutritional status of the population using Primary Health Care.¹1. Secretaria de Atenção à Saúde. Departamento de Atenção Básica. Marco de referência da vigilância alimentar e nutricional na atenção básica. Brasília: Ministério da Saúde; 2015. This surveillance aims to maintain an up-to-date diagnosis of issues related to food and nutrition, which are relevant to public health, providing support for planning and implementing measures aimed at improving the food and nutrition situation of the Brazilian population.²2.

https://sisaps.saude.gov.br/sisvan/publi... One of the main tools used to achieve this goal is the Food and Nutrition Surveillance System (Sistema de Vigilância Alimentar e Nutricional - SISVAN), where information on food consumption and nutritional status of individuals of both sexes, all age groups and race/skin color, schooling, and those belonging to traditional peoples and communities is recorded.²2. Ministério da Saúde (BR). Manual operacional para uso do Sistema de Vigilância Alimentar e Nutricional - SISVAN - v. 3.0 [Internet]. Brasília: Ministério da Saúde; 2017 [citado 2023 Jun 7]. 39 p.

Traditional peoples and communities are culturally diverse grups that self-identify as such. They have unique forms of social organization, inhabit specific territories and rely on natural resources as a condition for their cultural, social, religious, ancestral and economic reproduction, using knowledge, innovations and practices generated and transmitted through tradition for this purpose.³3.

Diário Oficial da União, Brasília (DF), 2007 Fev 8, Seção 1:316. Despite a legal framework established to ensure their sustainable development, various social vulnerabilities persist in the territories where these peoples live.⁴4. Piedras RC, Lima LL. Povos e comunidades tradicionais e a política de assistência social: uma revisão sistemática da literatura. Brazilian J Dev. 2022;8(8):60231-42. doi: 10.34117/bjdv8n8-348.
https://doi.org/10.34117/bjdv8n8-348... These vulnerabilities are attributed to the influence of a modernization paradigm, ethnocentrism, marginalization, and specially economic interests opposed to their modus vivendi.⁵5. Souza WKA.

From an epidemiological perspective, differences have been observed in these communities when compared to the general population. Association between body mass index (BMI) and higher prevalence of hypertension have been found in Quilombola communities, for instance.⁹9. Santos DMS, Prado BS, Oliveira CCC, Almeida-Santos MA.

The anthropometric monitoring of traditional peoples and communities is crucial for planning public policies aimed at promoting health, food and nutrition security. These indicators provide an indirect means to measure the state of food insecurity, guide intervention strategies and monitor the effectiveness of the policies implemented, either in a general or specific context, within each community.¹²12. Athila AR, Leite MS. “A medida da fome”: as escalas psicométricas de insegurança alimentar e os povos indígenas no Brasil. Cad Saude Publica. 2020;36(10):e00208019. doi: 10.1590/0102-311X00208019.

The objective of this study was to describe the prevalence of underweight and obesity indicators among individuals registered as traditional peoples and communities in the SISVAN, Brazil in 2019.

METHODS

Study design

This was a descriptive study, using individual secondary data on the nutritional status of individuals belonging to traditional peoples and communities in Brazil, registered on SISVAN in 2019.

Setting

SISVAN is a nationwide health information system that provides continuous data on the food and nutritional status of the population using Primary Health Care within the SUS. Since 2013, the System has provided specific information about traditional people and community.¹³13. RedeNutri. SISVAN web lança sua primeira versão revisada a partir de março 2013 [Internet]. [s.l.]: RedeNutri; 2013 [citado 2023 Set 9]. Disponível em: http://ecos-redenutri.bvs.br/tiki-read_article.php?articleId=646.
http://ecos-redenutri.bvs.br/tiki-read_a... In 2016, e-SUS Primary Care (e-SUS AB) strategy and SISVAN was integrated, leading to an increase in registrations in the System.¹⁴14. Ministério da Saúde (BR). Secretaria de Atenção à Saúde. Departamento de Atenção Básica. Integração entre e-SUS AB e SISVAN [Internet]. Brasília: Ministério da Saúde; 2017 [citado 2023 Jun 7]. Disponível em: Disponível em: https://aps.saude.gov.br/noticia/2479 .
https://aps.saude.gov.br/noticia/2479...

The data for this study were collected in the context of routine visits made by individuals from these communities to public health facilities of Primary Health Care, across the country, as recorded from January 1, 2019 to December 31, 2019.

In 2019, from which data were collected for this study, the Bolsa Família Program provided income transfers to needy families with the condition that they kept their children under 7 years of age in nutritional follow-up.¹1. Secretaria de Atenção à Saúde. Departamento de Atenção Básica. Marco de referência da vigilância alimentar e nutricional na atenção básica. Brasília: Ministério da Saúde; 2015.

Participants

Data on individuals registered in SISVAN were used, with inclusion criteria based on the record made in 2019 and the individual being recognized as belonging to traditional peoples and communities as indicated in the System’s registration and monitoring form. The year 2019 presented the highest number of records of traditional peoples and communities, and was selected. Other factors influencing the choice of this time period included its immediate proximity to 2020, when physical distancing measures were taken due to the COVID-19 pandemic emergency, and the fact that the Bolsa Família was in force and properly implemented, allowing for comparability with prior years and subsequent years following the resumption of the program.

The following data were excluded from the study: (i) duplicate observations, keeping the most recent record, (ii) records of adults weighing less than 30 kg and more than 300 kg or with a height greater than 2.20 m and less than 1.20 m, as recommended by the Ministry of Health for the Chronic Disease Risk and Protective Factors Surveillance Telephone Survey,¹⁵15.

Data Sources and Measurement

The individual data from SISVAN were obtained through an official letter, in which data access was requested from the Secretariat of Primary Health Care, accompanied by a duly completed Responsibility Agreement and the documentation listed in the specific ordinance.²⁰20. Brasil. Ministério da Saúde. Portaria nº 884, de 13 de dezembro de 2011 [Internet]. Diário Oficial da União, Brasília (DF) , 2011 Dez 14 [citado 2023 Jun 7], Seção 1:80. Disponível em: Disponível em: https://pesquisa.in.gov.br/imprensa/jsp/visualiza/index.jsp?jornal=1&pagina=80&data=14/12/2011 .
https://pesquisa.in.gov.br/imprensa/jsp/...

Regarding data measurement, it is worth noting that there are protocols for collecting anthropometric data within the scope of SISVAN, covering all stages of life. However, it is not possible to ensure that all professionals responsible for the data measurement used in this study had access to calibrated instruments or underwent standardized training, given the breadth and heterogeneity of the Brazilian reality. For children up to 2 years of age, it is recommended that weight be collected on pediatric scales, whether mechanical or digital, positioning the child to evenly distribute the weight. Length should be measured using infantometers, with the child’s head firmly placed against the fixed part of the equipment, the neck straight and the chin away from the chest, aligned with the Frankfurt plane.¹⁸18. Ministério da Saúde (BR). Secretaria de Atenção à Saúde. Departamento de Atenção Básica. Orientações para a coleta e análise de dados antropométricos em serviços de saúde: norma técnica do Sistema de Vigilância Alimentar e Nutricional - SISVAN. Brasília: Ministério da Saúde; 2011. 71 p. (Série G Estatística e Informação em Saúde).

For people over 2 years of age, it is important to ensure that weight is measured by means of mechanical platform scales or digital scales. The individual should be positioned with his or her back to the scale, barefoot, wearing little clothing, in the center of the equipment, standing upright, with feet together and the arms extended alongside the body. For height measurement a stadiometer is recommended. The individual should stand barefoot and without any head accessories, centered on the device, standing upright, with arms extended alongside the body, looking straight ahead at eye level, with their head raised, and aligned with the Frankfurt plane.¹⁸18.

In addition to these measures, the exclusion criterion for implausible anthropometric values was applied to reduce possible errors in weight and height measurements, or in the digitization of information in the System.

Statistical methods

Data quality was investigated and no evidence of inconsistencies was identified, as recommended by the WHO.¹⁶16. World Health Organization, United Nations Children’s Fund. Recommendations for data collection, analysis and reporting on anthropometric indicators in children under 5 years old [Internet]. Geneva: World Health Organization; 2019 [citado 2023 Jun 7]. 145 p. Available from: Available from: https://www.who.int/publications/i/item/9789241515559 .
https://www.who.int/publications/i/item/... The graphic material related to this verification is available in supplementary material. The distribution of absolute and relative frequencies of sociodemographic and anthropometric characteristics was described by sex. Bivariate quantile regressions were conducted, with “weight”, “height” or “BMI” as the dependent variable; and “age” as the independent variable. Quadratic terms were included in all models, accounting for curvilinear relationships between each of the independent variables and the dependent variable. Each bivariate regression was performed five times for the percentiles 3, 15, 50, 85, and 97. Scatterplots were created, showing the observed points and the estimated curves in the quantile regressions for each percentile mentioned.

Z-scores were calculated based on weight, height, age, and gender data, according to the growth curves provided by the WHO.²²22. Vidmar SI, Cole TJ, Pan H. Standardizing anthropometric measures in children and adolescents with functions for egen: update. Stata J. 2013;13(2):366-78. doi: 10.1177/1536867X1301300211.
https://doi.org/10.1177/1536867X13013002... The mean and 95% confidence interval (95%CI) of BMI and weight-for-age, height-for-age, and BMI-for-age Z-scores were calculated according to each traditional people and community. Finally, the prevalence and its respective 95%CI were described for the following indicators: low height-for-age in children and adolescents; low weight-for-age, low weight and height-for-age, and overweight in children; and underweight, obesity and overweight in adults.

The manipulation of the database related to the total population registered on SISVAN was performed using the Google Colab application for the Python programming language. After selection, the data were stored, cleaned and analyzed using the Stata software, version 16. Missing values have been handled with row exclusion.

Ethical aspects

Anonymous individual information was provided by the Secretariat of Primary Health Care of the Ministry of Health (Secretaria de Atenção Primária à Saúde, do Ministério da Saúde - SAPS/MS) and was exclusively used for statistical purposes. In obtaining the data, the social relevance of the study and the assessment of potential risks and benefits were taken into account, as recommended by the National Health Council (Conselho Nacional de Saúde - CNS). The study project was approved by the Research Ethics Committee of the Universidade de Fortaleza (Coética/Unifor): with the approval process initiated in April 2020, under Opinion No. 4,348,452 and Certificate of Submission for Ethical Appraisal (CAAE) No. 31540320.9.1001.5052.

RESULTS

The study population was comprised of 13,944 individuals of both sexes, aged between 0 and 101 years. This sample size resulted from the application of inclusion and exclusion criteria based on 79,100,900 records from 2019, nationwide (Figure 1).

The most reported traditional peoples and communities were riverine dwellers (50.3%), geraizeiros (13.3%) and quilombolas (9.9%). The communities with the smallest population registered on SISVAN were the babassu coconut breakers (< 0.1%), Faxinalenses (0.1%) and the Roma people (0.1%).

Table 1
Sociodemographic and anthropometric characteristics of Brazilians belonging to traditional peoples and communities registered on SISVAN, by sex (N = 13,944), Brazil, 2019

There was a predominance of participants from the North region (56.4%), followed by the Northeast (20.8%), Southeast (18.9%), South (2.2%) and Midwest (1.6%) regions. There was a higher frequency in the age group of 10 to 19 years in females (23.4%), while in males, it was from 5 to 9 years old (28.3%). The most common race/skin color was mixed-race (65.0%), followed by White (13.7%), Asian (7.1%), Black (5.0%) and Indigenous (4.3%). The most frequent education level was “incomplete elementary education or less” (58.3%), and the majority of records were made on the e-SUS AB system (56.7%) (Table 1).

There was a higher prevalence of indicators of low height-for-age among male children and adolescents (14.2%), when compared to the same indicators in females (11.8%). There was no evidence of a higher prevalence of indicators of low weight-for-age and high weight-for-age among children and adolescents of either sex. Regarding records of the adult female population, there was a higher prevalence of obesity (23.0%) and overweight (57.6%) when compared to males (11.3% and 42.4%, respectively) (Table 1).

The distribution of weight by age according to sex is presented in Figure 2. It could be seen that the median weight, height and BMI of the individuals did not show a linear relationship with age, but rather a curvilinear one. Observations regarding weight in children were similarly distributed between sexes, being slightly higher for males at the age of five. The distribution of height in the population aged 0 to 19 years differed between the sexes, becoming more evident from the age of 14, when the median for females tended to stabilize, compared to the median observed for males, which continued to increase until the age of 19. In addition, a higher median BMI was observed in the age group of 50 to 55 years for both sexes.

The communities with the lowest mean weight-for-age and height-for-age Z-scores were traditional riverine dwellers. Babassu coconut breaker communities had the lowest mean BMI-for-age and BMI Z-scores in adult females. Roma people showed the highest mean weight-for-age Z-scores up to 5 years of age, while the Faxinalense communities reported the highest mean weight-for-age Z-scores in children and BMI in females. The highest mean BMI in males occurred in the Pomeranian communities (Figure 3).

Prevalence of anthropometric indicators is presented in Figure 4 and detailed in the supplementary material. The prevalence of low height-for-age was higher in Roma communities (44.4%). In riverine communities, there was a higher prevalence of low height-for-age (18.5%), which was statistically significant when compared to the prevalence in other communities - with the exception of retireiro, artisanal fisherman, extrativist, fundo e fecho de pasto and Faxinalense communities. Among the traditional peoples and communities in which there were cases indicative of low weight-for-age, riverine communities showed a higher prevalence of this indicator (6.5%), when compared to the same prevalence among Caiçara (1.4%) and Geraizeiro (2.4%) communities. Faxinalense communities showed a higher prevalence of obesity (75.1%), when compared to the same prevalence in other traditional peoples and communities - with the exception of terreiro, Pomeranian, rubber tapper, Retireiro, Roma and Caiçara communities.

DISCUSSION

Higher prevalence of low weight-for-age in children was observed in riverine dwellers, when compared to other traditional peoples and communities. Riverine dwellers and artisanal fisherman communities also showed the highest prevalence of low height-for-age among children and adolescents. Faxinalense communities presented the highest prevalence of obesity among adults, as well as overweight, when compared to other communities studied.

The most prevalent traditional people or community were the riverine dwellers, who showed the second-highest prevalence of low height-for-age and low weight-for-age indicators. These communities are predominantly located in the Amazon territory, and their health indicators have been often described in international reports.¹¹11. Fundo das Nações Unidas para a Infância.

The majority of traditional peoples or communities in this study showed indicators of low weight-for-age or low height-for-age in children or adolescents. According to the criteria proposed by the WHO,¹⁶16. World Health Organization, United Nations Children’s Fund.

https://www.who.int/publications/i/item/... the prevalence of low weight-for-age is considered high at the threshold of 10%, a figure that artisanal fishing communities exceeded by 43.0% (14.3%). In the coastal area of Salvador, the capital city of the state of Bahia, the precariousness of the fishing sector was investigated in artisanal fishing and shellfish gatherer communities in 2020, revealing a lower level of food security and social support, as well as diminished expectations regarding receiving welfare benefits and collaborating with other sectors of society.²⁷27.

Roma, Caiçara and Faxinalense communities showed the highest percentages of obesity among adults. Issues related to a high prevalence of obesity in Roma people were observed in Slovakia, where the prevalence of obesity in adults was 29% higher when compared to that of the general adult population

This phenomenon was explained by eating habits related to increased caloric intake, in a context of limited access to health services.¹⁰10.

At the international level, the Brazilian concept of traditional peoples and communities³3. Brasil. Casa Civil. Decreto nº 6.040, de 7 de fevereiro de 2007. Institui a Política Nacional de Desenvolvimento Sustentável dos Povos e Comunidades Tradicionais. Diário Oficial da União, Brasília (DF), 2007 Fev 8, Seção 1:316. finds a semantic parallel in the expression “peasants and other people working in rural areas”, as applied in the United Nations Declaration on the Rights of Peasants and Other People Working in Rural Areas.³⁰30. United Nations. United Nations Declaration on the Rights of Peasants and Other People Working in Rural Areas [Internet]. Conference Report; 2018 Oct 8 [cited 2023 Set 9]; Human Rights Council - Thirty-ninth session 2018 10-28 September. Available from: https://www.fao.org/family-farming/detail/en/c/1197482/.
https://www.fao.org/family-farming/detai... This document also raises concern about the disproportionate suffering of these peoples from poverty, hunger and malnutrition; in this sense, the Declaration proposes measures to ensure the right of these peoples to food and food sovereignty, emphasizing the fight against child malnutrition, the determination of their food systems, and the restriction on the use of agricultural products harmful to health.

The limitations of this study can be categorized into two groups: the generalization of the results beyond the respective study populations; and the degree of precision of the anthropometric indicators used. Given the possibility of a higher number of individuals seeking welfare benefits in this population, and taking into consideration the heterogeneities among the Brazilian regions with regard to the human and material resources and use of healthcare services, generalizations of the results of this study should not be extended to individuals belonging to traditional peoples and communities who are not recorded in SISVAN. It is worth highlighting the nature of the indicators used, which approximate complex phenomena related to malnutrition and overweight, focused on the population thinking and, therefore, should be understood with the necessary clinical caveats, incorporating anthropological and genetic insights.

When describing the distribution of anthropometric indicators and the prevalence of underweight and obesity, the importance of the SISVAN for monitoring the nutritional status of traditional peoples and communities, some of the most vulnerable groups to food insecurity in Brazil, is reaffirmed. The findings highlight significant differences in nutritional status indicators among the communities observed, revealing the need for targeted research, within the context of each community, supporting interventions aimed at reducing or eliminating inequities experienced in the field of food and nutrition.
