Impact of implementation of front-of-package nutrition labeling on sugary beverage consumption and consequently on the prevalence of excess body weight and obesity and related direct costs in Brazil: An estimate through a modeling study.

RATIONALE: Intake of sugary beverages has been associated with obesity and chronic non-communicable diseases, thereby increasing the direct health costs related to these diseases. Front-of-package nutrition labeling (FoPNL) aims to help consumers understand food composition, thereby improving food choices and preventing the development of such diseases. OBJECTIVE: To estimate, over five years, the impact of implementing FoPNL in Brazil on the prevalence of excess body weight and obesity in adults who consume sugary beverages and the direct costs related to such problems. METHODS: A simulation study to performed to estimate the effect of FoPNL implementation on the prevalence of excess body weight and obesity. The VIGITEL research database (2019), published in the 2020 report, was used in this study (the final sample consisted of 12,471 data points representing 14,380,032 Brazilians). The scenarios were considered: base (trend in sugary beverage intake); 1 (base scenario associated with the changes in energy content of the purchased beverages observed after the first phase of the Chilean labeling law (-9.9%); and 2 (scenario 1 associated with reformulation of beverages, total energy reduction of -1.6%). Changes in body weight were estimated using the simulation model of Hall et al. (2011) over five years. A linear trend in the prevalence of obesity and excess body weight in the Brazilian population was considered. The impact of the prevalence of obesity and excess body weight on body mass index was estimated. In addition, the direct health costs related to obesity were estimated. RESULTS: Energy consumption from sugary beverages after FoPNL implementation is expected to be reduced by approximately 28 kcal/day (95% CI, -30 to -27) considering scenario 1. In scenarios 1 and 2, without FoPNL, the prevalence of obesity and excess body weight over five years was estimated to be 25.3% and 25.2%, and 64.4% and 64.2%, respectively. By extrapolating the results to the entire Brazilian population, it was observed that the implementation of FoPNL may reduce the prevalence of obesity by -0.32 percentage points and -0.35 percentage points (scenario 1 and 2, respectively) and excess body weight by -0.42 percentage points and -0.48 percentage points (scenarios 1 and 2, respectively) in five years. It is estimated that after five years of implementation, it will be possible to save approximately US$ 5,5 millions (95% CI 4,7 to 8,8) in scenario 1, reaching approximately US$ 6,1 millions (95% CI 5,3 to 9,8) in scenario 2. CONCLUSION: The results of this modeling study indicate that FoPNL may reduce prevalence of excess body weight and obesity, representing strategic public policies for obesity prevention.

Avoidable diet-related deaths and cost-of-illness with culturally optimized modifications in diet: The case of Brazil.

BACKGROUND: Dietary risk factors have an important impact on premature deaths and disabilities due to non-communicable diseases. In this study, we perform diet optimization to design different dietary scenarios taking into account food prices and preferences and evaluate the number of deaths that would be prevented as well as the economic burden and costs from the health system that would be saved in Brazil. METHODS: We used dietary intake and food prices data from the nationwide Household Budget Survey (HBS) and the National Dietary Survey (NDS) 2017-2018. Linear programming models were performed to design five scenarios which different sets of key diet modifications at the least deviation from the baseline consumption. Comparative risk assessment models were used to estimate the health impacts of optimized dietary changes on mortality and the economic impacts on morbidity (hospitalizations) and premature deaths. RESULTS: The optimized diets were, on average, more expensive than the baseline diets, varying from Int$ (international dollar) 0.02/day to 0.52/day/adult. The number of deaths prevented or postponed varied from 12,750 (10,178-15,225) to 57,341 (48,573-66,298) according to the different scenarios. The diet modifications would save from 50 to 219 million in hospitalizations and from 239 to 804 million yearly in productivity losses with the reduction of premature deaths. CONCLUSION: A substantial number of deaths and costs due to hospitalization and productivity losses would be avoidable even with small changes in diets. However, even the cheapest intervention might be prohibitive for deprived families, yet subsidies and social policies could contribute to improving diets.

Time trends and social inequalities in infant and young child feeding practices: national estimates from Brazil's Food and Nutrition Surveillance System, 2008-2019.

OBJECTIVE: To describe the time trends and socio-economic inequalities in infant and young child feeding practices in accordance with the Brazilian deprivation index (BDI). DESIGN: This time-series study analysed the prevalence of multiple breast-feeding and complementary feeding indicators based on data from the Brazilian Food and Nutrition Surveillance System, 2008-2019. Prais-Winsten regression models were used to analyse time trends. Annual percent change (APC) and 95 % CI were calculated. SETTING: Primary health care services, Brazil. PARTICIPANTS: Totally, 911 735 Brazilian children under 2 years old. RESULTS: Breast-feeding and complementary feeding practices differed between the extreme BDI quintiles. Overall, the results were more favourable in the municipalities with less deprivation (Q1). Improvements in some complementary feeding indicators were observed over time and evidenced such disparities: minimum dietary diversity (Q1: Δ 47·8-52·2 %, APC + 1·44, P = 0·006), minimum acceptable diet (Q1: Δ 34·5-40·5 %, APC + 5·17, P = 0·004) and consumption of meat and/or eggs (Q1: Δ 59·7-80·3 %, APC + 6·26, P < 0·001; and Q5: Δ 65·7-70·7 %, APC + 2·20, P = 0·041). Stable trends in exclusive breast-feeding and decreasing trends in the consumption of sweetened drinks and ultra-processed foods were also observed regardless the level of the deprivation. CONCLUSIONS: Improvements in some complementary food indicators were observed over time. However, the improvements were not equally distributed among the BDI quintiles, with children from the municipalities with less deprivation benefiting the most.

Estimation of the economic benefits for the public health system related to salt reduction in Costa Rica.

Excessive salt and sodium intake are strongly associated with high blood pressure and increased risk of cardiovascular disease. High blood pressure in turn is the main risk factor for the global burden of morbidity and mortality. The prevalence of this disease in the adult population of Costa Rica in 2018 was 37.2%. Costa Rica has limited information on the economic costs for the public health system and related of the prevalence of this type of disease mediated by dietary factors such as salt intake. OBJECTIVE: to estimate the economic benefits for the public health system related to salt reduction in Costa Rica for the year 2018. METHODOLOGY: estimation of the economic benefits for the public healthcare costs and productivity losses associated to reducing the per capita salt consumption of Costa Ricans to 5g/day, including the estimation of the Years of Life Productive Lost and of the direct costs on consultations, hospitalizations, and medications for the Costa Rica Social Security System. RESULTS: The total annual costs of hospitalization, consultations, and medications attributable to excessive salt intake in the population older than 15 years of age for the year 2018, were estimated at USD $15.1 million. The highest were in hospitalizations (53%), followed by consultations and medications (32% and 15%, respectively). CONCLUSION: NCDs caused by excessive salt intake represent important economic losses for the country, not only in terms of direct health costs, but also indirect due to the increase in years of potential life lost due to premature deaths because of CVD, which causes significant losses of human capital and, therefore, to the economy and the development of Costa Rica.

Time trends and social inequalities in child malnutrition: nationwide estimates from Brazil's food and nutrition surveillance system, 2009-2017.

OBJECTIVE: In Brazil, national estimates of childhood malnutrition have not been updated since 2006. The use of health information systems is an important complementary data source for analysing time trends on health and nutrition. This study aimed to examine temporal trends and socio-demographic inequalities in the prevalence of malnutrition in children attending primary health care services between 2009 and 2017. DESIGN: Time trends study based on data from Brazil's Food and Nutrition Surveillance System. Malnutrition prevalence (stunting, wasting, overweight and double burden) was annually estimated by socio-demographic variables. Prais-Winsten regression models were used to analyse time trends. Annual percent change (APC) and 95 % CI were calculated. SETTING: Primary health care services, Brazil. PARTICIPANTS: Children under 5 years old. RESULTS: In total, 15,239,753 children were included. An increase in the prevalence of overweight (APC = 3·4 %; P = 0·015) and a decline in the prevalence of wasting (-6·2 %; P = 0·002) were observed. The prevalence of stunting (-3·2 %, P = 0·359) and double burden (-1·4 %, P = 0·630) had discrete and non-significant reductions. Despite the significant reduction in the prevalence of undernutrition among children in the most vulnerable subgroups (black, conditional cash transfer's recipients and residents of poorest and less developed areas), high prevalence of stunting and wasting persist alongside a disproportionate increase in the prevalence of overweight in these groups. CONCLUSIONS: The observed pattern in stunting (high and persistent prevalence) and increase in overweight elucidate setbacks in advances already observed in previous periods and stresses the need for social and political strategies to address multiple forms of malnutrition.

Estimating the health and economic effects of the voluntary sodium reduction targets in Brazil: microsimulation analysis.

BACKGROUND: Excessive sodium consumption is one of the leading dietary risk factors for non-communicable diseases, including cardiovascular disease (CVD), mediated by high blood pressure. Brazil has implemented voluntary sodium reduction targets with food industries since 2011. This study aimed to analyse the potential health and economic impact of these sodium reduction targets in Brazil from 2013 to 2032. METHODS: We developed a microsimulation of a close-to-reality synthetic population (IMPACTNCD-BR) to evaluate the potential health benefits of setting voluntary upper limits for sodium content as part of the Brazilian government strategy. The model estimates CVD deaths and cases prevented or postponed, and disease treatment costs. Model inputs were informed by the 2013 National Health Survey, the 2008-2009 Household Budget Survey, and high-quality meta-analyses, assuming that all individuals were exposed to the policy proportionally to their sodium intake from processed food. Costs included costs of the National Health System on CVD treatment and informal care costs. The primary outcome measures of the model are cardiovascular disease cases and deaths prevented or postponed over 20 years (2013-2032), stratified by age and sex. RESULTS: The study found that the application of the Brazilian voluntary sodium targets for packaged foods between 2013 and 2032 could prevent or postpone approximately 110,000 CVD cases (95% uncertainty intervals (UI): 28,000 to 260,000) among men and 70,000 cases among women (95% UI: 16,000 to 170,000), and also prevent or postpone approximately 2600 CVD deaths (95% UI: - 1000 to 11,000), 55% in men. The policy could also produce a net cost saving of approximately US$ 220 million (95% UI: US$ 54 to 520 million) in medical costs to the Brazilian National Health System for the treatment of CHD and stroke and save approximately US$ 71 million (95% UI: US$ 17 to170 million) in informal costs. CONCLUSION: Brazilian voluntary sodium targets could generate substantial health and economic impacts. The reduction in sodium intake that was likely achieved from the voluntary targets indicates that sodium reduction in Brazil must go further and faster to achieve the national and World Health Organization goals for sodium intake.

Modelling the effect of compliance with WHO salt recommendations on cardiovascular disease mortality and costs in Brazil.

INTRODUCTION: Cardiovascular diseases (CVDs) represent the main cause of death among non-communicable diseases (NCDs) in Brazil, and they have a high economic impact on health systems. Most populations around the world, including Brazilians, consume excessive sodium, which increases blood pressure and the risk of CVDs. OBJECTIVE: To model the estimated deaths and costs associated with CVDs, which are mediated by increased blood pressure attributable to excessive sodium consumption in adults from the perspective of the Brazilian public health system in 2017. METHODS: We employed two macrosimulation methods, using top-down approaches and based on the same relative risks. The models estimated the mortality and costs-of-illness attributable to excessive sodium intake and mediated by hypertension for adults aged over 30 years in 2017. Direct healthcare cost data (inpatient care, outpatient care and medications) were extracted from the Ministry of Health information systems and official records. RESULTS: In 2017, an estimated 46,651 deaths from CVDs could have been prevented if the average sodium consumption had been reduced to 2 g/day in Brazil. Premature deaths related to excessive sodium consumption caused 575,172 Years of Life Lost and US$ 752.7 million in productivity losses to the economy. In the same year, the National Health System's costs of hospitalizations, outpatient care and medication for hypertension attributable to excessive sodium consumption totaled US$192.1 million. The main causes of death and costs associated with CVDs were coronary heart disease and stroke, followed by hypertensive disease, heart failure and aortic aneurysm. CONCLUSION: Excessive sodium consumption is estimated to account for 15% of deaths by CVDs and to 14% of the inpatient and outpatient costs associated with CVD. It also has high societal costs in terms of premature deaths. CVDs are a leading cause of disease and economic burden on the global, regional and country levels. As a largely preventable and treatable conditions, CVDs require the strengthening of cost-effective policies, supported by evidence, including modeling studies, to reduce the costs relating to illness borne by the Brazilian public health system and society.

OBJECTIVE: To estimate the cost attributable to arterial hypertension, diabetes and obesity in the Unified Health System of Brazil in 2018. METHOD: The study estimated the cost attributable to non-communicable chronic diseases based on relative risk and population prevalence of hypertension, diabetes, and obesity, considering the cost of hospitalizations, outpatient procedures, and medications distributed by the SUS to treat these diseases. Cost data were obtained from SUS information systems. The analysis explored the cost of disease according to sex and age in the adult population. RESULTS: The total cost of hypertension, diabetes, and obesity in the SUS reached R$ 3.45 billion (95%CI: 3.15-3.75) in 2018, that is, more than US$ 890 million. Of this amount, 59% referred to the treatment of hypertension, 30% to diabetes, and 11% to obesity. The age group from 30 to 69 years accounted for 72% of the total costs, and women accounted for 56%. When obesity was considered separately as a risk factor for hypertension and diabetes, the cost attributable to this diseases reached R$ 1.42 billion (95%CI: 0.98-1.87), i.e., 41% of the total cost. CONCLUSIONS: The estimates of costs attributable to the main chronic diseases associated with inadequate diet revealed a heavy economic burden of these disorders for the SUS. The data show the need to prioritize integrated and intersectoral policies for the prevention and control of hypertension, diabetes, and obesity, and may support the advocacy for interventions such as fiscal and regulatory measures to ensure that the objectives of the United Nations Decade of Action on Nutrition are met.

Developing and applying a costing tool for hypertension and related cardiovascular disease: Attributable costs to salt/sodium consumption.

This paper proposes a costing tool for hypertension and cardiovascular disease by adapting cost-of-illness methodologies to estimate the attributable burden of excessive salt intake on cardiovascular disease. The methodology estimates the changes in blood pressure that result from each gram change in salt intake and links diet to the direct and indirect costs of cardiovascular diseases (CVD), such as coronary heart disease, stroke, hypertensive disease, aortic aneurysm, heart failure, pulmonary embolism, and rheumatic heart, using the relative risks of disease and the prevalence of salt consumption in the population. The methodology includes (a) identifying major diseases and conditions related to excessive salt intake and relevant economic cost data available, (b) quantifying the relationship between the prevalence of excessive salt intake and the associated risk of disease morbidity and mortality using population attributable risks (PAR), (c) using PARs to estimate the share of total costs directly attributed to excessive salt intake, and (d) undertaking a sensitivity analysis of key epidemiological and economic parameters. The costing tool has estimated that, in 2013, US$ 102.0 million (95% uncertainty interval-UI: US$ 96.2-107.8 million) in public hospitalizations could be saved if the average salt intake of Brazilians were reduced to 5 g/d, corresponding to 9.4% (95% UI: 8.9%-9.9%) of the total hospital costs by CVDs. This methodology of cost of illness associated with salt consumption can be adapted to estimate the burden of other dietary risk factors and support prevention and control policies in Brazil and in other countries.

Iniciativas para a redução do consumo de sódio no Brasil: avaliação e análise de impacto / Initiatives for reducing sodium intake in Brazil: impact analysis and evaluation

Introdução: Dietas inadequadas são importantes fatores de risco preveníveis para doenças crônicas não-transmissíveis (DCNTs), no mundo. Entre os nutrientes críticos associados às DCNTs, o consumo excessivo de sódio é o principal fator de risco para doenças cardiovasculares, mediadas pela hipertensão arterial. Diferentes fontes dietéticas contribuem para o consumo de sódio, portanto sua redução depende de múltiplas estratégias paralelas e complementares que podem ser avaliadas antes de sua implementação por meio de macro e microssimulações de cenários. Objetivos: Os objetivos deste estudo são desenvolver e aplicar metodologias de macro e microssimulação para estimar o impacto do consumo excessivo de sódio e das metas voluntárias de redução do sódio sobre a morbimortalidade da população e os custos da doença no Brasil. Métodos: Foram produzidos quatro manuscritos baseados em dados de inquéritos nacionais, estatísticas nacionais e sistemas de informação do Sistema Único de Saúde. O primeiro manuscrito avalia o impacto das metas voluntárias entre 2011-2017 nos teores de sódio de categorias prioritárias no Brasil. O segundo detalha o desenvolvimento e aplicação de uma metodologia de macrossimulação para estimar os custos da doença atribuíveis ao consumo de sódio. O terceiro artigo usa macrossimulações para estimar as mortes e custos atribuíveis ao excesso de sódio no Brasil. O último estima, por microssimulação, o impacto projetado em 20 anos das metas voluntárias de redução do sódio sobre a morbimortalidade e custos diretos e indiretos em saúde. Resultados: O consumo excessivo de sódio representa uma grande carga sobre a saúde da população brasileira, assim como para os gastos do SUS e perdas econômicas para a sociedade. Estimou-se que seriam atribuíveis ao excesso de sódio, em 2017, 47.017 mortes por todas doenças cardiovasculares associadas à hipertensão (equivalentes a 585 mil anos de vida perdidos), responsáveis por US$ 195 milhões em despesas ao SUS e US$ 800 milhões em perdas de produtividade por mortalidade precoce. As metas voluntárias de redução do sódio no Brasil resultaram na redução do conteúdo médio de sódio de 5% a 28% nos produtos e uma redução final de 0,25 g/dia no consumo diário de sal da população entre 2011 e 2017. Em 20 anos, a continuidade dessas metas voluntárias nacionais evitaria 112 mil casos e 2.524 mortes por doenças isquêmicas do corção e doenças cerebrovasculares, cujos custos diretos e indiretos de tratamento somariam US$ 292,5 milhões. Conclusões: Os resultados evidenciam os prejuízos à saúde da população e os elevados custos ao SUS e à sociedade causados pelo consumo excessivo de sódio e apoiam a priorização da redução do consumo de sódio na agenda de saúde. Além disso, considerando a multiplicidade das fontes dietéticas de sódio e nos impactos limitados das metas voluntárias sobre a morbimortalidade e os custos das doenças cardiovasculares, é necessário ampliar o impacto da reformulação de alimentos e fortalecer outras estratégias voltadas à redução das demais fontes de sódio. Nesse sentido, as modelagens de impacto de fatores dietéticos sobre DCNTs demonstram ser importantes ferramentas para subsidiar a formulação e implementação de políticas mais efetivas no Brasil e em outros países.

Introduction: Inadequate diets are important preventable risk factors for non-communicable diseases (NCDs) in the world. Among critical nutrients associated with NCDs, excessive sodium consumption is the largest risk factor for cardiovascular diseases, mediated by hypertension. Different dietary sources contribute to sodium intake; therefore, sodium reduction depends on multiple parallel and complementary strategies, which can be evaluated previously to implementation through macro and microsimulations. Objectives: The objectives of this study were to develop and apply macro and microsimulation methodologies to evaluate the impact of excessive sodium intake and of the national voluntary targets for sodium reduction on morbimortality and costs of disease in Brazil. Methods: Four manuscripts were produced based on data from national surveys, national statistics and health information systems of the National Health System (SUS). The first manuscript evaluated the impact of the national voluntary sodium targets on the sodium content of priority food categories. The second detailed the development and application of a cost of disease macrosimulation methodology for estimating attributable costs to sodium. The third manuscript used macrosimulations to estimate the attributable deaths and costs to excessive sodium intake in Brazil. The last manuscript used microsimulation models to estimate the projected a 20-year impact of the voluntary sodium targets on morbimortality and direct and indirect health costs. Results: Excessive sodium intake represents a large health burden to Brazilians, and an economic burden to the National Health System and to society. In 2017, it was estimated that 47,017 deaths from all cardiovascular diseases (CVD) mediated by hypertension (equivalent to 585 thousand years of lofe lost), US$ 195 million in expenditures to the National Health System and US$ 800 million in productivity losses to premature deaths were attributable to excessive sodium intake. The voluntary sodium reduction targets for processed and ultraprocessed foods have reduced the average sodium content of foods in 5% to 28% and the average salt intake of the population in 0.25 g/day, from 2011 to 2017. The continuity of the voluntary targets over 20 years would prevent or postpone 112 thousand CVD cases and 2,524 deaths from coronary heart disease and stroke, which represent US$ 292.5 in direct and indirect treatment costs. Conclusions: The results highlight the burden of excessive sodium intake to health and its costs to the National Health System and to the Brazilian society, which support the need for prioritizing sodium reduction in the health agenda. Besides, considering the multiple dietary sources of sodium and the limited impact of the voluntary targets on the incidence, deaths and costs of cardiovascular diseases, it is necessary to expand the impact of food reformulation and strengthen other strategies addressed to the other dietary sources of sodium. Therefore, modeling the impact of dietary factors on NCDs on related morbimortality and costs is an important tool to formulate and implement more cost-effective policies in Brazil and in other countries.

Desses custos, 59% foram referentes ao tratamento da hipertensão, 30% ao do diabetes e 11% ao da obesidade. No total, 72% dos custos foram com indivíduos de 30 a 69 anos de idade e 56%, com mulheres. Considerando separadamente a obesidade como fator de risco para hipertensão e diabetes, os custos atribuíveis a essa doença chegaram a R$ 1,42 bilhão (IC95%: 0,98 a 1,87), ou seja, 41% dos custos totais. Conclusões. As estimativas dos custos atribuíveis às principais doenças crônicas associadas à alimentação inadequada evidenciam a grande carga econômica dessas doenças para o SUS. Os dados mostram a necessidade de priorizar políticas integradas e intersetoriais para a prevenção e o controle da hipertensão, do diabetes e da obesidade e podem apoiar a defesa de intervenções como medidas fiscais e regulatórias para alcançar os objetivos da Década de Ação das Nações Unidas sobre Nutrição.(AU)

ABSTRACT Objective. To estimate the cost attributable to arterial hypertension, diabetes and obesity in the Unified Health System of Brazil in 2018. Method. The study estimated the cost attributable to non-communicable chronic diseases based on relative risk and population prevalence of hypertension, diabetes, and obesity, considering the cost of hospitalizations, outpatient procedures, and medications distributed by the SUS to treat these diseases. Cost data were obtained from SUS information systems. The analysis explored the cost of disease according to sex and age in the adult population. Results. The total cost of hypertension, diabetes, and obesity in the SUS reached R$ 3.45 billion (95%CI: 3.15-3.75) in 2018, that is, more than US$ 890 million. Of this amount, 59% referred to the treatment of hypertension, 30% to diabetes, and 11% to obesity. The age group from 30 to 69 years accounted for 72% of the total costs, and women accounted for 56%. When obesity was considered separately as a risk factor for hypertension and diabetes, the cost attributable to this diseases reached R$ 1.42 billion (95%CI: 0.98-1.87), i.e., 41% of the total cost. Conclusions. The estimates of costs attributable to the main chronic diseases associated with inadequate diet revealed a heavy economic burden of these disorders for the SUS. The data show the need to prioritize integrated and intersectoral policies for the prevention and control of hypertension, diabetes, and obesity, and may support the advocacy for interventions such as fiscal and regulatory measures to ensure that the objectives of the United Nations Decade of Action on Nutrition are met.(AU)

RESUMEN Objetivo. Estimar los costos atribuibles a la hipertensión arterial, la diabetes y la obesidad en el Sistema Único de Salud (SUS) de Brasil en el 2018. Métodos. Se estimaron los costos atribuibles a las enfermedades crónicas no transmisibles a partir de los riesgos relativos y de las tasas de prevalencia poblacional de hipertensión, diabetes y obesidad, teniendo en cuenta los costos de hospitalización, los procedimientos ambulatorios y los medicamentos distribuidos por el SUS para el tratamiento de esas enfermedades. Los datos de costos se obtuvieron en los sistemas de información de salud disponibles en el SUS. En el análisis se exploraron los costos de las enfermedades según el sexo y la edad de la población adulta. Resultados. Los costos totales atribuibles a la hipertensión, la diabetes y la obesidad en el SUS alcanzaron R$ 3,450 milliones (IC 95%: de 3,15 a 3,75) en el 2018, o sea, más de US$ 890 millones. De esos costos, 59% correspondió al tratamiento de la hipertensión, 30% al de la diabetes y 11% al de la obesidad. En total, 72% de los costos correspondieron a personas de 30 a 69 años y 56%, a mujeres. Al considerarse por separado la obesidad como factor de riesgo de hipertensión y diabetes, los costos atribuibles a esa enfermedad alcanzaron R$ 1.420 millones (IC 95%: de 0,98 a 1,87), o sea, 41% del total. Conclusiones. Las estimaciones de los costos atribuibles a las principales enfermedades crónicas relacionadas con la alimentación inadecuada ponen de manifiesto la pesada carga económica de esas enfermedades para el SUS. Los datos muestran la necesidad de priorizar políticas integradas e intersectoriales para la prevención y el control de la hipertensión, la diabetes y la obesidad, y permiten apoyar la defensa de intervenciones como medidas fiscales y regulatorias para alcanzar los objetivos del Decenio de las Naciones Unidas de Acción sobre la Nutrición.(AU)

Regional Overview on the Double Burden of Malnutrition and Examples of Program and Policy Responses: Latin America and the Caribbean.

BACKGROUND: Hunger, food insecurity, stunting, anemia, overweight, and noncommunicable diseases (NCDs) may coexist in the same person, household, and community in Latin America and the Caribbean (LAC). The double burden of malnutrition (DBM) is an important cause of disability and premature death, which could be addressed with comprehensive policies such as the Plan of Action for the Prevention of Obesity in Children and Adolescents. This paper summarizes the main policies and actions aimed to prevent undernutrition and obesity. SUMMARY: Several countries are implementing the Plan of Action, Caribbean Public Health Agency is actively supporting Ministries of Health, Education, and Sport to develop school nutrition policies and strategies to create health-promoting environments at school and in their surrounding communities. Chile is implementing the comprehensive child protection system "Chile Crece Contigo" that integrates health, social development, and educational activities to optimize growth and childhood cognitive-motor development. Brazil is implementing policies and plans to commit to international targets regarding food and nutrition security, NCDs and their risk factors. Key Messages: The DBM exists in the Americas and contributes to disability and premature death. The Region is making progress implementing policies and actions addressing the DBM. However, stronger political will and leadership are needed to enact legislation and policies that create and support enabling -environments.

Introduction of inappropriate complementary feeding in the first year of life and associated factors in children with low socioeconomic status. / Introdução de alimentos não recomendados no primeiro ano de vida e fatores associados em crianças de baixo nível socioeconômico.

The study aimed to identify factors associated with the introduction of inappropriate complementary feeding in the first year of life in children living in municipalities (counties) with low socioeconomic statusl. This was a cross-sectional multicenter study in 1,567 children 12 to 59 months of age in 48 municipalities participating in the Brazil Without Poverty plan in the South of Brazil. A structured questionnaire was applied to the children's parents to obtain socio-demographic information and the age at which inappropriate complementary foods were introduced for the first time in complementary feeding. Prevalence of introduction of sugar before four months of age was 35.5% (n = 497; 95%CI: 33.1-38.0). The prevalence rates for the introduction of cookies/crackers, creamy yogurt, and jelly before six months of age were 20.4% (n = 287; 95%CI: 18.3-22.3), 24.8% (n = 349; 95%CI: 22.4-27.1), and 13.8% (n = 192; 95%CI: 12.0-15.7), respectively. Associations were identified between low maternal schooling (PR = 1.25; 95%CI: 1.03-1.51) and low monthly family income (PR = 1.22; CI95%: 1.01-1.48) and the introduction of inappropriate complementary feeding. The study identified the introduction of inappropriate complementary feeding in the first year of life among children in municipalities with high socioeconomic vulnerability in the South of Brazil, associated with low maternal schooling and low monthly family income.

A organização da Vigilância Alimentar e Nutricional no Sistema Único de Saúde: histórico e desafios atuais / Organization of Food and Nutritional Surveillance within the Brazilian National Health System: history and current challenges

A Política Nacional de Alimentação e Nutrição ressalta a importância do Sistema de Vigilância Alimentar e Nutricional - SISVAN, que se destina à identificação do diagnóstico descritivo e analítico da situação alimentar e nutricional da população brasileira, contribuindo para que se conheça a natureza e a magnitude dos problemas nutricionais do país. Este artigo visa apresentar o histórico das ações da Vigilância Alimentar e Nutricional no Brasil, desde sua idealização até a prática atual, destacando a superação das limitações encontradas ao longo dos anos, o fortalecimento obtido por meio dos marcos legais e os desafios enfrentados neste momento. Entende-se hoje que o SISVAN só pode ser conduzido utilizando-se uma combinação de estratégias, sendo as principais: o sistema informatizado do SISVAN, os inquéritos populacionais, as Chamadas Nutricionais, a análise das bases de dados nacionais da saúde, o acesso à produção científica e o financiamento de pesquisas sobre o tema.

Conditional cash transfers are associated with a small reduction in the rate of weight gain of preschool children in northeast Brazil.

Programs providing cash transfers to poor families, conditioned upon uptake of preventive health services, are common in Latin America. Because of the consistent association between undernutrition and poverty, and the role of health services in providing growth promotion, these programs are supposed to improve children's growth. The impact of such a program was assessed in 4 municipalities in northeast Brazil by comparing 1387 children under 7 y of age from program beneficiary households with 502 matched nonbeneficiaries who were selected to receive the program but who subsequently were excluded as a result of quasi-random administrative errors. Anthropometric status was assessed 6 mo after benefits began to be distributed, and beneficiary children were 0.13 Z-scores lighter (weight-for-age) than excluded children, after adjusting for confounders (P = 0.024). The children's growth trajectories were reconstructed by copying up to 10 recorded weights from their Ministry of Health growth monitoring cards and by relating each weight to the child's age, gender, and duration of receipt of the program benefit in a random effects regression model. Totals of 472 beneficiary and 158 excluded children under 3 y of age were included in this analysis. Each additional month of exposure to the program was associated with a rate of weight gain 31 g lower than that observed in excluded children of the same age (P < 0.001). This failure to respond positively to the program may have been due to a perception that benefits would be discontinued if the child started to grow well. Nutrition programs should guard against giving the impression that poor growth will be rewarded.
