Resumo Esta revisão objetivou analisar a insegurança alimentar e nutricional no meio rural brasileiro, bem como os instrumentos de mensuração utilizados na avaliação dessa situação. Realizou-se revisão sistemática nas bases de dados SciELO, Pubmed e o portal de periódicos da CAPES, usando os termos de busca: ‘segurança alimentar’ e ‘rural’. Posteriormente foi realizada busca reversa dentro dos artigos selecionados. Os critérios de inclusão foram: artigos originais, relacionados à (in) segurança alimentar e nutricional na população rural brasileira. Foram incluídos 12 estudos. A maioria utilizou a Escala Brasileira de Insegurança Alimentar-EBIA e questionários socioeconômicos para avaliar a insegurança alimentar (IA), sendo encontrada associação entre eles. Cinco estudos abordaram o aspecto nutricional pela antropometria, porém não encontraram associação com a IA. O consumo alimentar foi avaliado por quatro estudos e foi observada associação. Os resultados mostram alta prevalência de IA no meio rural em relação à população analisada na Pesquisa Nacional por Amostra de Domicílio-PNAD nos anos de 2009 e 2013, assim como alta prevalência de IA grave. Conclui-se que o meio rural se apresenta em vulnerabilidade, principalmente quanto à questão alimentar e nutricional e aos determinantes socioeconômicos atrelados.
Background Food insecurity is a public health concern that affects health and quality of life, but its association with cardiometabolic risk is not well established. Thus, this systematic review evaluated the association between food insecurity and cardiometabolic risk factors in adults and the elderly. Methods Search was conducted according to the PRISMA protocol using Scielo, LILACS and PubMed databases. We included original articles published in Portuguese, English, and Spanish, which assessed the association between food insecurity and cardiometabolic risk factors in adults and the elderly. The search identified 877 articles but only 11 were included in the review. Results Food insecurity was directly associated with cardiometabolic risk (excess weight, hypertension, dyslipidemias, diabetes, and stress) after adjusting for interfering factors. A limitation of the cross-sectional study design is that the cause-effect relation between food insecurity and cardiometabolic risk cannot be established. Conclusions We conclude that food insecurity has a direct relationship with cardiometabolic risk factors, especially excess weight, hypertension, and dyslipidemias. The identification of food insecurity as health problems can contribute to the implementation of efficient public policies for the prevention and control of chronic diseases. Protocol registration This review was registered on PROSPERO-International Prospective Register of Systematic Reviews – CRD4201911549.
A transdisciplinaridade pode ser entendida como a convergência de disciplinas que se conectam entre si, em um ou vários momentos dentro de uma organização, e assim, permitindo uma nova compressão da realidade. Esta aproximação de conteúdos permite produzir conhecimentos considerando as múltiplas dimensões.
The majority of studies on anemia are focused on children and women of reproductive age. Although the disease is a widespread public health problem, studies that include the rural population are scarce. This study determined the prevalence of anemia and associated factors in adults and the elderly living in the rural area of a municipality in Minas Gerais. Twelve rural communities were included. During home visits, hemoglobin levels were measured using a hemoglobinometer to check for the presence or absence of anemia. Additionally, anthropometric data and food insecurity data based on the Brazilian Food Insecurity Scale (EBIA) were collected. A questionnaire about socioeconomic, demographic, and housing conditions was applied. Analyses were performed using the Stata software version 13.0. Spearman correlation and regression analysis logistics were performed (p < 0.05) on 124 families (n = 297 farmers). The prevalence of anemia was 41.1%, being higher among women (55.7%). Additionally, 40.1% of the farmers were food insecure; 52.7% and 80.5% presented excess weight and cardiovascular risk, respectively. Poverty was a reality for 39.7% of individuals. A positive correlation between hemoglobin levels and per capita income was found as well as a negative correlation with EBIA scores and cardiovascular risk. Multivariate analysis showed that individuals experiencing food insecurity, the elderly, and those who do not own a property, were more likely to be anemic. Farmers with per capita income above 1/2 minimum wage were less likely to have anemia. The prevalence of anemia in the group studied was higher than previous studies. The disease is associated with factors that also predispose to food insecurity. The improvement of the determinants of insecurity can contribute to the fight against anemia.
Objective The natural probiotic kefir is fermented milk, and may have effects on satiety and voluntary energy intake. This randomized crossover trial aimed to determine whether kefir, consumed with low- or high-glycemic index meals, affects appetite and subsequent food intake. Methods This is a cross-sectional study with families of farmers who supplied Programa Nacional de Alimentação Escolar from 2011 to 2016 in the city of Viçosa, Minas Gerais, Brazil. To assess Food Insecurity, the Brazilian Food Insecurity Scale was applied to the person responsible for purchasing and producing meals in the family. The nutritional aspect was analyzed through the measurement of hemoglobin to check for anemia among family members and using the household food availability survey, where it was possible to analyze the amount of calories available for consumption, as well as the origin and kind of food. Results 27 families were evaluated, totalizing 91 individuals. With the Escala Brasileira de Insegurança Alimentar, it was found that 25.9% of the families were in light food insecurty situation. When caloric availability was assessed, 11.0% of families were considered insecure. In contrast, 59.0% of families had high calorie availability per capita (>3000 calories). Of the total households, 14.8% had more than 50.0% of the calories available for consumption coming from their own production. The foods most commonly produced for self-consumption were fresh vegetables, which are the most common ones supplied to Programa Nacional de Alimentação. In addition, the main source of kilocalories for the families were fresh and minimally processed foods. The presence of anemia in at least 1 resident was detected in 29.6% of households, with a negative correlation between the hemoglobin value (g/dL) and the Escala Brasileira de Insegurança Alimentar score. Conclusion It appears that the majority of the families of farmers supplying Programa Nacional de Alimentação Escolar are in a situation of Food and Nutritional Security, both by Escala Brasileira de Insegurança Alimentar and by the household availability of food. However, we cannot ignore the percentage of insecure families, since this situation can lead to other problems. Therefore, it is necessary to constantly assess the family situation of Fodd Insecurty and encourage production for self-consumption so that it contributes to food availability and quality. For this reason, the we highlight relevance of programs that strengthen the production and commercialization of food from family farming.
This study aimed to evaluate the association between the use of pesticides, symptoms of intoxication and health conditions of family farmers in the Mata Mineira area, Brazil. This is a cross-sectional study with 48 family farmers from a municipality in the Zona da Mata, Minas Gerais. A semi-structured questionnaire was applied to obtain demographic, socioeconomic information and characterization of the use of pesticides. Blood samples were collected from farmers for biochemical tests and evaluation of markers of exposure to pesticides. It was found that 75% of farmers used pesticides in food production, most of these products being extremely toxic. These farmers showed changes in plasma cholinesterase, erythrocyte cholinesterase and butyrylcholinesterase, markers of exposure to pesticides. There was an association between spraying for more than 4 hours/day and reporting of acute symptoms of intoxication, as well as between the use of pesticides and the presence of chronic non-communicable diseases. Multivariate analysis indicated that non-compliance with the period of re-entry into crops after the use of pesticides remained as an explanatory variable for lung disease. We infer that acute symptoms, as well as chronic non-communicable diseases reported by family farmers, may be associated with the use of pesticides.
A insegurança alimentar no meio rural é muito presente. Destaca-se ainda as mudanças de hábitos alimentares que podem afetar o estado nutricional e o crescente uso de agrotóxicos. Este trabalho objetivou avaliar a situação de segurança alimentar de agricultores familiares, estado nutricional e percepção em relação ao uso de agrotóxicos na produção de alimentos. O estudo foi realizado com 48 agricultores familiares, sendo coletadas informações referentes ao estado nutricional, disponibilidade domiciliar de alimentos e consumo alimentar. Além destes pontos, avaliou-se a percepção dos agricultores sobre o uso de agrotóxicos. A segurança alimentar foi avaliada pela disponibilidade de alimentos e o consumo alimentar pelo Questionário de Frequência de Consumo Alimentar. A Análise de Conteúdo foi mobilizada para avaliação da percepção do uso de agrotóxicos. Os resultados indicaram que 89,6% dos agricultores estavam em situação de segurança alimentar quanto às perspectivas da disponibilidade de alimentos, contudo 54,2% apresentam distrofia nutricional. Verificou-se ainda que menos de 50% dos agricultores familiares consumiam frutas e hortaliças todo dia, enquanto que 80% consumiam açúcares e doces diariamente. Utilizavam agrotóxicos na produção de alimentos, 75% dos agricultores, sendo que destes cerca de 70% relataram não consumir os alimentos produzidos. O Índice de Massa Corporal elevado apresentou associação com uso atual de agrotóxicos (p=0,046). Ainda, 85,4% dos agricultores afirmaram que os agrotóxicos impactam na saúde, com predomínio da percepção de riscos relacionada à manifestação de doenças. Conclui-se que se faz necessária a conscientização dos agricultores sobre a alimentação e ações voltadas para os riscos da exposição aos agrotóxicos.
