RESUMO

BACKGROUND: Korea's child meal support program (CMSP) aims to reduce food and nutrition insecurity (FNI) and improve health among children from low-income households. AIM: We examined the impact of different types of CMSP on children's FNI and health in Korea, analyzing meal frequency and healthful food consumption (FNI), and general health and depression (health) among child meal card (CMC) and facility meal service (FMS) participants compared with nonparticipants. METHODS: The 2018 Comprehensive Survey on Korean Children data were analyzed. Precisely, 847 children from low-income households aged 9-17 were categorized into CMC (n = 331), FMS (n = 209), and income-eligible nonparticipants (n = 307). Propensity score-weighted generalized linear models assessed CMSP's impact on FNI and health. Stratified generalized linear models examined heterogeneity in FNI-health associations by CMSP status. RESULTS: CMC participants reported more frequent breakfast consumption (odds ratio [OR] = 0.662, p < 0.05) but poorer self-rated general health (OR = 1.890, p < 0.05); FMS participants were less likely to have three meals (OR = 1.814, p < 0.05), fruits and vegetables (OR = 2.194, p < 0.001), and protein-rich foods daily (OR = 1.695, p < 0.05) than nonparticipants. Health risks associated with healthful food consumption and meal frequency were more pronounced among CMC and FMS/nonparticipants, respectively. CONCLUSION: CMSP had a limited impact on reducing FNI and improving health among children from low-income households. CMC appeared more effective than FMS in alleviating FNI, notwithstanding potential health concerns. Food assistance programs should seek comprehensive enhancements in children's food and nutrition security and health.

RESUMO

In recent years, the interest in food and nutrition insecurity in high-income countries has skyrocketed. However, its recognition in Europe is still developing. This perspective summarizes the evidence on food and nutrition insecurity across Europe in terms of prevalence, consequences, and current mitigation strategies, with the aim of outlining the challenges and opportunities for dietitians. Prevalence in the general population ranges between 5% and 20%, with higher rates identified in women, children, older adults, single-parent households, those with low educational attainment, and on low or unstable income and/or employment. In users of food aid, the prevalence of food insecurity is above 70%. Responses to food and nutrition insecurity include welfare policies and food assistance programs at regional and national levels. However, most current strategies are not successful in tackling the structural drivers of food and nutrition insecurity, nor do they guarantee diet quality. Despite limited involvement to-date, dietitians can play an important role in addressing food and nutrition insecurity across Europe. This narrative identifies 4 areas: 1) create awareness of the existence and severity of food and nutrition insecurity, 2) advocate for comprehensive, robust data on the determinants and prevalence, 3) partner with diverse stakeholders, social assistance providers, local authorities, and nongovernmental organizations in a comprehensive, intersectoral, and integrated manner, 4) participate in the development of political instruments and interventions that ensure equitable access to high-quality safe food.

RESUMO

We examine food and nutrition security and the household's ability to respond adequately to shock and stressors during the COVID-19 pandemic. Specifically, we assess household resilience to food insecurity and its relation to future food security. We use two survey rounds collected during the pandemic - before and after the second wave of the pandemic-from the vulnerable population living in slums in Tanzania. The findings reveal that many households have low resilience to shock. We find that COVID-19 reduced access to food in 68% of the households and left about 30% without any food to eat. We also find that micronutrient consumption significantly declined among households who reported food insecurity following the second wave of COVID-19. We also find that the probability of experiencing food insecurity reduced with the initial resilience level. High resilient households have a higher likelihood of maintaining or diversifying more their diets even when are exposed to shock. The disruption of income-generating activities was found as a leading pathway through which COVID-19 affected household food security. The findings suggest that with persisting COVID-19 pandemic and the low level of micronutrients consumption, the nutrition of children and adult household members of the vulnerable population is at stake.

RESUMO

ntroduction: state of Food and Nutritional Security (FNS) is one that should guarantee the right of permanent access to quality food and in sufficient quantity without prejudicing access to other basic rights. In Brazil, rural family farming establishments represent 84.4% of total agricultural establishments and contribute to more than 70% of all food consumed by Brazilians. In this context, the production of the coffee commodity stands out. However, despite being food producers, they do not earn a good income. Slow economic activity can lead to loss of wages and income, illness, as well as food insecurity (FNiS). In addition, the molecular effects of FNiS are poorly studied, especially epigenetic.Objective: the objective of the present study is to analyze the association between Brain-Derived Neurotrophic Factor (BDNF) DNA methylation and socio demographic, lifestyle, and epigenetic factors, among coffee farmers in the Caparaó zone, in Espirito Santo, Southeast Brazil.Methods: the study was carried out in 22 randomly selected coffee producing communities in Zona Caparaó, an area that produces coffee of recognized quality. A total of 570 coffee farming households, 18 to 60 years of age, were included in the study by answering a questionnaire about socioeconomic characteristics, land use and ownership, behavior, health, and working conditions. FNiS evaluation was carried out using the Brazilian Food Insecurity Scale. BDNF exon I methylation was examined by methylation-specific PCR. Body mass index and biochemical analyses were performed. Logistic regression models were used to verify factors associated with FNiS (p<0.05). Data were analyzed using the Stata® statistical software package version 14.Results: the FNiS prevalence found was 23.68%. In multivariable logistic regression, the occurrence of FNiS was associated with hypermethylation of exon I of the BDNF promoter exon I [ORa = 5.03 (95% (1.98, 12.82)] when compared to the unmethylated gene. Moreover, FNiS was associated with excessive workload [ORa = 3.36 (1.23, 9.22)], possession of less land (hectares) [ORa = 0.77 (0.67, 0.90)] and greater number symptoms and / or illnesses in real life [ORa = 1.12 (1.04.1.20)].Conclusion: there is a high prevalence of Food Insecurity in the studied region. This phenomenon was associated with epigenetic factors (BDNF methylation), excessive workload, small land ownership and a greater number of diseases / symptoms. Food insecurity is a psychosocial stressor that can lead to epigenetic changes in the BDNF gene, responsible for regulating cognitive functions, neuronal survival and involved in the genesis of psychiatric diseases.


Introdução: o Estado de Segurança Alimentar e Nutricional (SAN) é aquele que deve garantir o direito de acesso permanente à alimentação de qualidade e em quantidade suficiente sem prejudicar o acesso a outros direitos básicos. No Brasil, os estabelecimentos de agricultura familiar rural representam 84,4% do total de estabelecimentos agropecuários e contribuem com mais de 70% de todos os alimentos consumidos pelos brasileiros. Nesse contexto, destaca-se a produção da commodity café. No entanto, apesar de serem produtores de alimentos, não auferem bons rendimentos. A lenta atividade econômica pode levar à perda de salários e renda, doenças e insegurança alimentar (INSAN). Além disso, os efeitos moleculares da INSAN são pouco estudados, sobretudo epigenéticos.Objetivos: o objetivo do presente estudo é analisar a associação entre a metilação do promotor do BDNF e a INSAN e a associação da INSAN com fatores sociodemográficos, de estilo de vida e epigenéticos, em cafeicultores da zona do Caparaó, no Espírito Santo, Sudeste do Brasil.Método: o estudo foi realizado em 22 comunidades cafeeiras selecionadas aleatoriamente na Zona do Caparaó, área que produz café de reconhecida qualidade. Um total de 570 famílias de cafeicultores, entre 18 a 60 anos, foram incluídos no estudo e responderam a um questionário sobre características socioeconômicas, uso e posse da terra, hábitos de vida, saúde e condições de trabalho. A avaliação da INSAN foi realizada por meio da Escala Brasileira de Insegurança Alimentar. A metilação do éxon I do BDNF foi examinada por PCR específica para metilação. Índice de massa corporal e análises bioquímicas foram realizadas. Modelos de regressão logística foram utilizados para verificar os fatores associados à INSAN (p<0,05). Os dados foram analisados usando o software estatístico Stata® versão 14.Resultados: a prevalência de INSAN encontrada foi de 23,68%. Na regressão logística multivariada, a ocorrência de INSAN foi associada a hipermetilação do éxon I do promotor do gene BDNF [ORa = 5,03 (95% (1,98, 12,82)] quando comparado ao gene não metilado. Além disso, a INSAN foi associada a carga de trabalho excessiva [ORa = 3,36 (1,23, 9,22)], posse de menos hectares de terra [ORa = 0,77 (0,67, 0,90)] e maior número de sintomas e/ou doenças da vida real [ORa = 1,12 (1.04.1.20)].Conclusão: o estudo mostrou uma alta prevalência de Insegurança Alimentar na região analisada. Esse fenômeno foi associado a fatores epigenéticos (metilação do gene BDNF), carga horária excessiva, pequena propriedade de terra e maior número de doenças/sintomas. A INSAN pode ser um estressor capaz de promover alterações epigenéticas no gene BDNF, importante gene regulador da cognição, crescimento e sobrevivência neuronal e envolvido com doenças psiquiátricas.

RESUMO

Enquanto crises econômicas desencadeiam o aumento da insegurança alimentar (IA) e da desigualdade de gênero (DG), o apoio social tem mostrado aliviar esses impactos. No entanto, diferentemente de outros choques econômicos, a pandemia de Covid-19 incluiu no cenário de crise o isolamento social. Este estudo utilizou dados de pesquisa transversal coletados em 18 países da América Latina (AL) para avaliar as mudanças nas percepções de DG e sua associação com a IA e o apoio social durante período de crise econômica na região. Os resultados mostraram aumentos graduais nas percepções de DG na AL e que os entrevistados com IA e baixo apoio social eram os mais propensos a perceber a DG. Mulheres são mais vulneráveis à IA e à violência doméstica, e o isolamento social pode ser um agravante. Políticas públicas devem garantir que mulheres tenham maior controle sobre a renda e bens produtivos. (AU)


Social support has been shown to mitigate increased food insecurity (FI) and gender inequality (GI) triggered by economic crises. However, unlike other shocks to the economy, the crisis triggered by the Covid-19 pandemic included social isolation. This study used data from a cross-sectional study collected in 18 countries in Latin America to evaluate changes in perceptions of GI and its association with FI and social support in the region during the economic crisis. The findings show a gradual increase in perceptions of GI in FI and that interviewees suffering from FI and low levels of social support were more likely to perceive GI. Women are more vulnerable to FI and domestic violence, and social isolation may be an aggravating factor. Public policy should ensure that women have greater control over income and productive assets. (AU)

RESUMO

BACKGROUND: Presidents with no possibility of re-election overvalue far-future rewards and succumb to terminal logic behavior (TLB), responding to end-of-tenure legacy concerns despite political context. Government authorities perceiving the outgoing government is losing power at the end of term behave under the logic of strategic defection (SD), dissociating from the outgoing government once it is perceived powerless. In countries where re-election is impossible and government turnover and inconstant political parties are concerns, governmental officials at all levels may show TLB and SD during transitions that affect policy sustainability. OBJECTIVES: This study aimed to understand the context during presidential transitions that makes TLB and SD relevant, whether TLB and SD affect sustainability of food and nutrition security policy (FNSP), and the tactics for navigating transitions that favor sustainability. METHODS: A case-study design was used with semi-structured qualitative interviews and document review of news articles in Guatemala. Purposeful criteria and snowball sampling were used to recruit 52 policy actors implementing an FNSP across 2 transitions; 252 news articles from the referenced period covering topics on policy programmatic areas were purposefully sampled. Interviews were analyzed using coding and thematic analyses. News articles were analyzed using a priori thematic coding for verifying themes in interviews and data triangulation. RESULTS: Governmental officials were replaced by others during transitions; political parties were perceived as inconstant. TLB and SD occurred at all levels and had consequences for sustainability of FNSP: implementation slow-down, dysfunctional collaboration, inefficient use of resources, benefits not reaching targeted groups, and loss of momentum. These occurred through individual, institutional, and political mechanisms. Civil society, international organizations, and government adopted tactics for maximizing sustainability. CONCLUSIONS: Understanding governmental officials' experiences and the extent to which TLB and SD occur and affect sustainability could be advantageous to develop compensatory actions for reaching long-term FNSP goals.

RESUMO

Biofortification of staple crops has a potential for addressing micronutrient deficiencies, such as vitamin A deficiency (VAD), which are prevalent in South Africa. The poor acceptability of provitamin A (PVA)-biofortified foods could be improved by combining them with other food items to produce modified traditional dishes. The nutritional composition of the dishes could also be improved by the modification. The study aimed to investigate the effect of replacing white maize and cream-fleshed sweet potato (CFSP)] with PVA-biofortified maize and orange-fleshed sweet potato (OFSP) on the nutritional composition of South African traditional dishes. The protein, fibre, total mineral (ash), lysine, and iron concentrations of the PVA maize phutu (traditional porridge) composite dishes (control), were not significantly different (P > 0.05) from those of white maize phutu composite dishes. However, the PVA concentration of PVA maize phutu composite dishes was higher than that of the white phutu composite dishes (P > 0.05). The OFSP had a significantly lower protein concentration, but a significantly higher (P > 0.05) fibre, ash, lysine, isoleucine, leucine, and PVA concentration, relative to the CFSP. The findings indicate that composite dishes in which white maize is replaced with PVA-biofortified maize, and switching over from CFSP to OFSP, would contribute to combating VAD in South Africa, and in other developing counties.

RESUMO

There is a need to incorporate nutrition into aspects of crop and water productivity to tackle food and nutrition insecurity (FNS). The study determined the nutritional water productivity (NWP) of selected major (groundnut, dry bean) and indigenous (bambara groundnut and cowpea) grain legumes in response to water regimes and environments. Field trials were conducted during 2015/16 and 2016/17 at three sites in KwaZulu-Natal, South Africa (Ukulinga, Fountainhill and Umbumbulu). Yield and evapotranspiration (ET) data were collected. Grain was analysed for protein, fat, Ca, Fe and Zn nutrient content (NC). Yield, ET and NC were then used to compute NWP. Overall, the major legumes performed better than the indigenous grain legumes. Groundnut had the highest NWPfat. Groundnut and dry bean had the highest NWPprotein. For NWPFe, Zn and Ca, dry bean and cowpea were more productive. Yield instability caused fluctuations in NWP. Water treatments were not significant (p > 0.05). While there is scope to improve NWP under rainfed conditions, a lack of crop improvement currently limits the potential of indigenous grain legumes. This provides an initial insight on the nutrient content and NWP of a limited number of selected grain legumes in response to the production environment. There is a need for follow-up research to include cowpea data. Future studies should provide more experimental data and explore effects of additional factors such as management practices (fertiliser levels and plant density), climate and edaphic factors on nutrient content and NWP of crops.

RESUMO

The origin of the social (public) politics related to food and nutrition in Brazil has a discontinuous and neglected course by the Brazilian State throughout its history. The objective of this article is to rescue this process and to identify elements that interfere in the insertion of the food and nutrition question in the Brazilian politics agenda. Thus, it reviews thepolitics and social programs formulated since the decade of 40s aimed to solve the problem of hunger in Brazil, identifying the changes of an epidemiological and nutritional transition of the local population. It is necessary to progress in the agreement of the biological manifestations of the hunger: malnutrition or obesity (bad nutrition) is reflected on a social development model that privileges the capital in detriment of the welfare state. Also it reflects the alimentary and nutritional context, therefore the submission of the society to the capital reflecting in the ways of eating, living, falling ill and dying.


O processo de surgimento das políticas (públicas) sociais relacionadas à alimentação e nutrição no Brasil tem um curso descontínuo e negligenciado pelo Estado brasileiro ao longo de sua história. Este artigo tem como objetivo resgatar este processo e identificar elementos que dificultam a inserção da questão alimentar e nutricional na agenda política brasileira. Assim, faz um breve resgate histórico sobre o conjunto de políticas e programas sociais formulados desde a década de quarenta com vistas ao enfrentamento do problema de fome no Brasil, sinalizando a mudança dos perfis epidemiológico e nutricional da população brasileira. É necessário avançar no entendimento de que as manifestações biológicas da fome - desnutrição ou obesidade (má nutrição) - são reflexos de um modelo de desenvolvimento social que privilegia o capital em detrimento do bem-estar social. A questão social também se manifesta perante o contexto alimentar e nutricional, pois a submissão da sociedade aos ditames do capital produz reflexos nos modos de comer, viver, adoecer e morrer das populações.
