Nutrition in times of Covid-19, how to trust the deluge of scientific information.

PURPOSE OF REVIEW: The Covid-19 pandemic has daunted the world with its enormous impact on healthcare, economic recession, and psychological distress. Nutrition is an integral part of every person life care, and should also be mandatorily integrated to patient care under the Covid-19 pandemic. It is crucial to understand how the Covid-19 does develop and which risk factors are associated with negative outcomes and death. Therefore, it is of utmost importance to have studies that respect the basic tenets of the scientific method in order to be trusted. The goal of this review is to discuss the deluge of scientific data and how it might influence clinical reasoning and practice. RECENT FINDINGS: A large number of scientific manuscripts are daily published worldwide, and the Covid-19 makes no exception. Up to now, data on Covid-19 have come from countries initially affected by the disease and mostly pertain either epidemiological observations or opinion papers. Many of them do not fulfil the essential principles characterizing the adequate scientific method. SUMMARY: It is crucial to be able to critical appraise the scientific literature, in order to provide adequate nutrition therapy to patients, and in particular, to Covid-19 infected individuals.

Gastrointestinal, nutritional, endocrine, and microbiota conditions in autism spectrum disorder. / Problemas gastrointestinales, nutricionales, endocrinológicos y de microbiota en el trastorno del espectro autista.

Gastrointestinal, nutritional, metabolic, endocrine, and microbiota medical problems in pediatric patients diagnosed with autism spectrum disorder (ASD) are some of the coexisting medical conditions in ASD diagnosis. Their prevalence reaches more than 91 % for gastrointestinal problems, up to 89 % for nutritional and metabolic disorders, more than 50 % for thyroid dysfunction, and up to 100 % for microbiota-related conditions. There is an urgency for medical practice to be updated and to include the assessment, testing, diagnosis, and treatment of these coexisting medical conditions in ASD diagnosis in the pediatric, adolescent, and adult population. A strict management of such conditions results in positive changes in the quality of life and symptoms based on which ASD is diagnosed many times. It should be based on high-quality scientific evidence with an adequate medical care and control.

Los problemas médicos gastrointestinales, nutricionales, metabólicos, endocrinológicos y de microbiota en los pacientes pediátricos con diagnóstico de trastorno del espectro autista (TEA) son parte de los problemas médicos concomitantes al diagnóstico. La prevalencia alcanza a más del 91 % en el caso de los problemas gastrointestinales, hasta el 89 % para los nutricionales y metabólicos, más del 50 % de disfunción tiroidea y hasta el 100 % para los relacionados con la microbiota. Es urgente actualizar la práctica médica para incluir la evaluación, testeo, diagnóstico y tratamiento de estos problemas médicos concomitantes al diagnóstico de TEA en la población pediátrica, adolescente y adulta. El tratamiento riguroso de dichos problemas genera cambios positivos en la calidad de vida y en la sintomatología bajo la cual el TEA se diagnostica en muchos casos. Debe basarse en evidencia científica de alta calidad, con control y cuidado médico adecuado.

COMPLEXITY OF PEDIATRIC CHRONIC DISEASE: CROSS-SECTIONAL STUDY WITH 16,237 PATIENTS FOLLOWED BY MULTIPLE MEDICAL SPECIALTIES.

OBJECTIVE: To assess demographic data and characteristics of children and adolescents with pediatric chronic diseases (PCD), according to the number of specialties/patient. METHODS: We performed a cross-sectional study with 16,237 PCD patients at outpatient clinics in one year. Data were analyzed by an electronic data system, according to the number of physician appointments for PCD. This study assessed: demographic data, follow-up characteristics, types of medical specialty, diagnosis (International Statistical Classification of Diseases and Related Health Problems - ICD-10), number of day hospital clinic visits, and acute complications. RESULTS: Patients followed by ≥3 specialties simultaneously showed a significantly higher duration of follow-up compared to those followed by ≤2 specialties [2.1 (0.4-16.4) vs. 1.4 (0.1-16.2) years; p<0.001] and a higher number of appointments in all specialties. The most prevalent medical areas in patients followed by ≥3 specialties were: Psychiatry (Odds Ratio - OR=8.0; confidence interval of 95% - 95%CI 6-10.7; p<0.001), Palliative/Pain Care (OR=7.4; 95%CI 5.7-9.7; p<0.001), Infectious Disease (OR=7.0; 95%CI 6.4-7.8; p<0.001) and Nutrology (OR=6.9; 95%CI 5.6-8.4; p<0.001). Logistic regressions demonstrated that PCD patients followed by ≥3 specialties were associated with high risk for: number of appointments/patient (OR=9.2; 95%CI 8.0-10.5; p<0.001), day hospital clinic visits (OR=4.8; 95%CI 3.8-5.9; p<0.001), emergency department visits (OR=3.2; 95%CI 2.9-3.5; p<0.001), hospitalizations (OR=3.0; 95%CI 2.7-3.3; p<0.001), intensive care admissions (OR=2.5; 95%CI 2.1-3.0; p<0.001), and deaths (OR=2.8; 95%CI 1.9-4.0; p<0.001). The diagnosis of asthma, obesity, chronic pain, and transplant was significantly higher in patients followed by ≥3 specialties. CONCLUSIONS: The present study showed that PCD patients who required simultaneous care from multiple medical specialties had complex and severe diseases, with specific diagnoses.

FACTORS ASSOCIATED WITH INADEQUATE MILK CONSUMPTION AMONG ADOLESCENTS: NATIONAL SCHOOL HEALTH SURVEY - PENSE 2012.

OBJECTIVE: To identify the prevalence and factors associated with inadequate milk consumption among adolescents. METHODS: This was a cross-sectional study based on secondary data from the National School Health Survey (2012), a Brazilian survey carried out using a self-administered questionnaire in a representative sample of 9th-grade students from public and private schools. The frequency of milk intake and its association with socio-demographic characteristics, food consumption and physical activity were estimated. A descriptive and inferential analysis of factors associated with inadequate milk consumption (no consumption at least one of the seven days of the week) was performed. A multiple logistic model was adjusted to control confounders. RESULTS: The sample included 108,828 adolescents and inadequate milk consumption ocurred in 58.9%. The final model included nine variables independently associated with inadequate milk intake: breakfast frequency less than 4 days per week (odds ratio [OR]=2.40; p<0.001), unprocessed or minimally processed foods intake less than 5 days per week (OR=1.93; p<0.001), living in the northeast region (OR=1.39; p<0.001), less maternal schooling (OR=1.35; p<0.001), physical inactivity (OR=1.33; p<0.001), attending public school (OR=1.26; p<0.001), not being white (OR=1.14; p<0.001), being older than 14 years old (OR=1.13; p<0.001) and having a habit of eating meals while watching TV or studying (OR=1.04; p=0.036). CONCLUSIONS: Inadequate milk consumption is prevalent among Brazilian adolescents. The identification of associated factors suggests the need to develop nutritional guidance strategies for the prevention of diseases that result from low calcium intake.

RESUMO Objetivo: Identificar a prevalência e os fatores associados ao consumo inadequado de leite em adolescentes. Métodos: Estudo transversal com base em dados secundários da Pesquisa Nacional de Saúde do Escolar (PeNSE; 2012), inquérito brasileiro realizado por meio de questionário autoaplicável em amostra representativa de alunos do nono ano do ensino fundamental de escolas públicas e privadas. Estimou-se a frequência da ingestão de leite e sua associação com características sociodemográficas, consumo alimentar e prática de atividade física. Foi realizada análise descritiva e inferencial dos fatores associados ao consumo inadequado de leite (ausência em pelo menos um dos sete dias da semana). Um modelo logístico múltiplo foi ajustado para controle das variáveis de confusão. Resultados: A amostra incluiu 108.828 adolescentes e o consumo inadequado de leite foi de 58,9%. O modelo final incluiu 9 variáveis independentemente associadas à ingestão inadequada de leite: frequência de desjejum inferior a 4 dias semanais (odds ratio [OR]=2,40; p<0,001), consumo de alimentos in natura e minimamente processados inferior a 5 dias semanais (OR=1,93; p<0,001), residir na Região Nordeste (OR=1,39; p<0,001), menor escolaridade materna (OR=1,35; p<0,001), inatividade física (OR=1,33; p<0,001), frequentar escola pública (OR=1,26; p<0,001), não ser da raça branca (OR=1,14; p<0,001), ter idade superior a 14 anos (OR=1,13; p<0,001) e possuir o hábito de realizar as refeições assistindo à TV ou estudando (OR=1,04; p=0,036). Conclusões: O consumo inadequado de leite é frequente entre adolescentes brasileiros. A identificação de fatores associados sugere a necessidade do desenvolvimento de estratégias de orientação nutricional para a prevenção de doenças resultantes da baixa ingestão de cálcio.

Forced international migration for refugee food: a scoping review / Migração internacional forçada e alimentação de refugiados: uma scoping review

Abstract Recent crisis and conflicts in African countries, the Middle East and the Americas have led to forced population migration and rekindled concern about food security. This article aims to map in the scientific literature the implications of forced migration on food and nutrition of refugees. Scoping Review, and database search: databases: PubMed Central, LILACS, SciElo, Science Direct and MEDLINE. Languages used in the survey were: English, Portuguese and Spanish, with publication year from 2013 to 2018. 173 articles were obtained and after removing of duplicates and full reading, 26 articles were selected and submitted to critical reading by two reviewers, resulting in 18 articles selected. From the analysis of the resulting articles, the following categories emerged: Food Inequity; Cultural Adaptation and Nutrition; Emerging Diseases and Strategies for the Promotion of Nutritional Health. Food insecurity is a marked consequence of forced international migration, and constitutes an emerging global public health problem, since concomitant with increasing population displacements also widens the range of chronic and nutritional diseases.

Perinatal origin of adult diseases. / Origen perinatal de enfermedades del adulto.

Three relevant, interrelated scientific advances are described: the concept of critical periods (CPs), the Barker Hypothesis (BH), and the underlying epigentic mechanisms involved. Critical periods are genetically programmed, highly sensitive time intervals during which the interaction between environment and individuals generates the development of physiological processes related to physical growth and development, survival (breastfeeding), social behavior, and learning. Barker hypothesis is based on the finding that prenatal malnutrition (for example, lowbirthweight) is closely related to mortality due to cardiovascular disease CVD) in the adult, and to the risk conditions leading to it: insuline resistence, metabolic syndrome, obesity, and high blood pressure. This association is no due to genetical causes, but secondary to nutritional deficits which in turn generate epigenetic mechanisms of methylation of DNA basis and cromatine proteines (histones), which do not modify the genetic code but modulate its expresion, reinforcing some genes, inhibiting others, regulating when and where they are expressed. These genes participate in the process called programming, consisting of permanent changes in the response to stimulation of metabolic and hormone regulators, such as, for example, increasing insuline resistence. Epigenetic changes persist even when original conditions (fetal or perinatal malnutrition) are no longer present. This, in turn, affects health of the offspring later in adult life, creating thus the same environmental prenatal conditions to the next generation. This transgenerational effects of early nutritional experiences are more frequent in population groups of por socioeconomic level, and consequently have serious implications in the future health of Latin American populations.

Se describen tres adelantos interrelacionados: el concepto de períodos críticos, la hipótesis de Barker y los mecanismos epigenéticos involucrados. Los primeros son intervalos temporales genéticamente programados, vinculados a procesos fisiológicos ligados al crecimiento y desarrollo físico del individuo (habilitación de vías nerviosas, replicación neuronal), a procesos relacionados con el apego madre-hijo, la lactancia, la socialización y el aprendizaje. La hipótesis de Barker sostiene que la desnutrición, en la etapa perinatal, se asocia a mayor mortalidad por enfermedad cardiovascular y a las alteraciones metabólicas que condicionan dicha enfermedad (síndrome metabólico, resistencia a la insulina, hipertensión). Esta asociación es secundaria a las alteraciones nutricionales que desencadenan mecanismos epigenéticos de metilación de bases del ADN o de histonas. Los cambios epigenéticos son permanentes y pueden tener efectos transgeneracionales, al afectar el ambiente perinatal en donde crece la descendencia, hecho relevante en países con poblaciones que viven en condiciones socioeconómicas desfavorables.

Maternal and familial correlates of anthropometric typologies in the nutrition transition of Colombia, 2000-2010.

OBJECTIVE: We aimed to assess the maternal and family determinants of four anthropometric typologies at the household level in Colombia for the years 2000, 2005 and 2010. DESIGN: We classified children 2) to assess stunting and overweight/obesity, respectively; mothers were categorized according to BMI to assess underweight (<18·5 kg/m2) and overweight/obesity (≥25·0 kg/m2). At the household level, we established four final anthropometric typologies: normal, underweight, overweight and dual-burden households. Separate polytomous logistic regression models for each of the surveyed years were developed to examine several maternal and familial determinants of the different anthropometric typologies. SETTING: National and sub-regional (urban and rural) representative samples from Colombia, South America. SUBJECTS: Drawing on data from three waves of Colombia's Demographic and Health Survey/Encuesta Nacional de Salud (DHS/ENDS), we examined individual and household information from mothers (18-49 years) and their children (birth-5 years). RESULTS: Higher parity was associated with an increased likelihood of overweight and dual burden. Higher levels of maternal education were correlated with lower prevalence of overweight, underweight and dual burden of malnutrition in all data collection waves. In 2010, participation in nutrition programmes for children <5 years, being an indigenous household, food purchase decisions by the mother and food security classification were also associated with the four anthropometric typologies. CONCLUSIONS: Results suggest that maternal and family correlates of certain anthropometric typologies at the household level may be used to better frame policies aimed at improving social conditions and nutrition outcomes.

2015 Health Survey of São Paulo with Focus in Nutrition: Rationale, Design, and Procedures.

This paper describes the design, sampling methods, and data collection procedures, with particular focus on dietary data, used for the 2015 Health Survey of São Paulo (Inquérito de Saúde de São Paulo, 2015 ISA-Capital) with Focus in Nutrition Study (2015 ISA-Nutrition). The ISA is a household cross-sectional, population-based survey that uses complex, stratified, multistage sampling to create a representative sample of residents from urban São Paulo, Brazil. The 2015 ISA-Nutrition comprised a sub-sample of the 2015 ISA-Capital and intended to include 300 adolescents (aged 12 to 19 years), 300 adults (aged 20 to 59 years), and 300 older adults (aged ≥60 years). From February 2015 to February 2016, 1737 individuals answered the first 24-h dietary recall (24HR), and 901 individuals consented to have their blood sample collected, to undergo anthropometric and blood pressure assessment, and to answer the second 24HR. The 2015 ISA-Nutrition aims to evaluate lifestyle-related modifiable factors in São Paulo's residents, as well as their association with biochemical and genetic markers, and environmental aspects related to cardiometabolic risk factors. This paper concludes that 2015 ISA-Nutrition may provide valuable insights into the cardiometabolic risk factors in a big city in an upper middle-income country and contribute to the formulation of health and nutritional policies.

Health Status and Anthropometric Changes in Resettled Refugee Children.

BACKGROUND: Recently the United States has experienced an increase in refugees. Pediatric refugees are at risk for health and nutrition problems. Literature on longitudinal change in nutritional status of resettled pediatric refugees is scant. OBJECTIVE: The present study reports the health and nutritional status of pediatric refugees and tracks changes in nutritional status. METHODS: Data were extracted retrospectively from the records of a community health center in Buffalo, NY. Two cohorts of refugees (0-18 years) were selected. Cohort A was followed during 5 years and consisted of 225 subjects whose initial visit occurred between January 1, 2007 and December 31, 2009. The 199 subjects in cohort B had an initial visit between January 1, 2013 and December 31, 2013 and were followed for 1 year. Cohort B was chosen because vitamin levels were available only for this group. Descriptive and anthropometric data, infectious disease status, and initial vitamin and hemoglobin levels were recorded. Height-for-age (HFA) z scores and body mass index (BMI) z scores were computed. Longitudinal changes were analyzed. RESULTS: The cohorts A and B differed in country of origin and infectious disease burden. On arrival, both cohorts exhibited HFA z scores reflecting short stature. BMI z scores were normal. HFA and BMI z scores increased during 5 years and 1 year for cohorts A and B, respectively. Anemia, vitamin D deficiency, and lead toxicity were identified. CONCLUSIONS: Resettled pediatric refugees were short. Some were stunted. Catch-up growth, however, occurred. There were increases in HFA and BMI z scores. Vitamin D deficiency, anemia, and lead toxicity were documented.

Challenges in the management of nutritional disorders and communicable diseases in child day care centers: a quantitative and qualitative approach.

In Brazil, although many children from low income families attend day care centers with appropriate hygiene practices and food programs, they have nutritional disorders and communicable diseases. This quantitative and qualitative cross-sectional study identified staff challenges in child day care centers and suggested alternative activity management to prevent nutritional disorders and communicable diseases. The study included 71 nursery teachers and 270 children from public and philanthropic day care centers (teacher to child ratios of 1:2.57 and 1:6.40, respectively). Interviews and focus groups were conducted with teachers and parents, and anthropometry and blood samples were drawn from the children by digital puncture. Children in philanthropic child day care centers were more likely to be hospitalized due to communicable diseases. Teachers from philanthropic child day care centers had lower age, income and education and higher work responsibilities based on the number of children and working time. The focus groups characterized institutions with organized routines, standard food practices, difficulties with caretaking, and lack of training to provide healthcare to children. Strategies to improve children's health in day care settings should focus on training of teachers about healthcare and nutrition.

Introduction: The nutritional status of adolescents pregnant women influences the health of the mother and the child. Objective: To determine the nutritional status and sociodemographic characteristics of pregnant adolescents women admitted to the PANI program during the year 2016 in the HRE. Methodology: A cross-sectional, observational, cross-sectional study with analytical component and complete records of pregnant patients were used from the tenth week of gestation in the period of January to December 2016, considering data on age, weight, height, gestational age, educational level, and the nutritional diagnosis made by the charts of Rosso - Mardones. Results: Of the 172 medical records used in the 12 to 19 year age range with a median of 17 (16.0 - 18.0) years, 6% (n = 11) and 94% (n=161) belonged to late adolescence and to the early adolescence correspondingly. The predominant educational level was middle education 39% (n = 67) and the third cycle of basic education (36%) (n = 62). Family income less than a minimum wage was of the 63% (and=108), up to a minimum wage of 37% (n = 63). The median weight was 58.0 (51.15 - 66.0) kg. An average size of 1.58 ± 0.06 m. The median gestational age of admission was 18 (12 - 27) weeks. The nutritional status of pregnant adolescents evaluated by Rosso - Mardones charts presented 46% low weight, 32% adequate, 13% overweight, 9% obesity. Conclusions: Of the pregnant women evaluated at the entrance of the Integral Nutritional Feeding Program the highest percentage of correspondence at low weight. The association between educational level and nutritional status was not found, nor was the association between income level and nutritional status found

Relationship between lipid and hematological profiles with adiposity in obese adolescents

Background: An excess of weight including obesity have reached epidemic rates in all age groups, both in developed and developing countries. It is notable that overweight children and adolescents have a higher likelihood of becoming obese adults and to present health-related problems early in life. Objetives: To verify associations of the lipid and hematological profiles with adiposity in obese adolescents beginning multidisciplinary weight loss therapy. Methods: This cross-sectional study was conducted with 85 adolescents of both genders, aged 12-19 years (Tanner staging 3 or 4) and body mass index greater than the 95th percentile. The sum of the triceps, subscapular and calf skinfolds and the waist circumference were used to estimate adiposity. Blood samples were collected from all patients after overnight fasting to analyze blood lipids (total cholesterol, high-density lipoprotein, low-density lipoprotein, very low-density lipoprotein and triglycerides), blood sugar and the hematological profile (hemoglobin, platelets and red blood cells). The Kolmogorov-Smirnov test and Spearman and Pearson correlation coefficients were used for statistical analysis with significance set for p-values ≤ 0.05. Results: There were statistical differences between genders for red blood cells (p-value = 0.000), hemoglobin (p-value = 0.000) and platelets (p-value = 0.002). Positive correlations were found for red blood cells (p-value = 0.031) and hemoglobin (p-value = ...

Statistical innovations improve prevalence estimates of nutrient risk populations: applications in São Paulo, Brazil.

The objective of this study was to estimate the prevalence of inadequate micronutrient intake and excess sodium intake among adults age 19 years and older in the city of São Paulo, Brazil. Twenty-four-hour dietary recall and sociodemographic data were collected from each participant (n=1,663) in a cross-sectional study, Inquiry of Health of São Paulo, of a representative sample of the adult population of the city of São Paulo in 2003 (ISA-2003). The variability in intake was measured through two replications of the 24-hour recall in a subsample of this population in 2007 (ISA-2007). Usual intake was estimated by the PC-SIDE program (version 1.0, 2003, Department of Statistics, Iowa State University), which uses an approach developed by Iowa State University. The prevalence of nutrient inadequacy was calculated using the Estimated Average Requirement cut-point method for vitamins A and C, thiamin, riboflavin, niacin, copper, phosphorus, and selenium. For vitamin D, pantothenic acid, manganese, and sodium, the proportion of individuals with usual intake equal to or more than the Adequate Intake value was calculated. The percentage of individuals with intake equal to more than the Tolerable Upper Intake Level was calculated for sodium. The highest prevalence of inadequacy for males and females, respectively, occurred for vitamin A (67% and 58%), vitamin C (52% and 62%), thiamin (41% and 50%), and riboflavin (29% and 19%). The adjustment for the within-person variation presented lower prevalence of inadequacy due to removal of within-person variability. All adult residents of São Paulo had excess sodium intake, and the rates of nutrient inadequacy were high for certain key micronutrients.

Estado nutricional en adolescentes, exceso de peso corporal y factores asociados / Nutritional status in adolescents, body excess weight and associated factors

Introducción: la adolescencia es una etapa crucial, con alta prevalencia de trastornos nutricionales, que luego continúan durante la vida adulta y se asocian con complicaciones a corto y a largo plazo. Objetivos: identificar la asociación entre el exceso de peso corporal y los antecedentes patológicos familiares de interés y algunos factores perinatales, la presencia de la hipertensión arterial y su relación con la historia familiar de hipertensión, el exceso de peso corporal y el incremento de adiposidad abdominal; y por último, identificar la presencia de acantosis nigricans y su relación con iguales factores. Métodos: se desarrolló un estudio descriptivo transversal para caracterizar el estado nutricional de los adolescentes de séptimo grado que asisten a la Secundaria Básica José María Heredia, en el curso 2009-2010. La población estuvo constituida por 192 adolescentes, a los cuales, con previo consentimiento de los padres, se les realizaron las mediciones antropométricas (peso, talla, circunferencia de cintura y se calculó el índice de masa corporal), y además se midió la tensión arterial y se buscaron signos clínicos de resistencia insulínica. También se aplicó una encuesta a los padres acerca de los antecedentes patológicos familiares y algunos datos de sus hijos. Resultados: se encontró que el 20,31 por ciento de los adolescentes presentaba sobrepeso u obesidad, lo cual se relacionó de forma significativa con la presencia de hipertensión arterial y signos clínicos de resistencia insulínica. La hipertensión arterial se halló en el 9,9 por ciento de los adolescentes, sin relación con factores hereditarios. Conclusiones: la obesidad y el sobrepeso corporal constituyen un problema de salud en la población adolescente estudiada, lo cual se asocia con la presencia de hipertensión arterial y resistencia insulínica, no existió relación en su comportamiento con factores no modificables (antecedentes patológicos familiares y personales)(AU)

Introduction: the adolescence is a decisive stage with a high level of prevalence of nutritional disorders that latter remains during the adulthood and are associated with short- and long term complications. Objectives: to identify the association between excess of body weight and the interesting family pathological backgrounds and some perinatal risks, the presence of high blood pressure and its relation to the family history of high blood pressure and the increase of abdominal adiposity and finally, to identify the presence of acanthosis nigricans and its relation with the similar factors. Methods: a cross-sectional and descriptive study was conducted to characterize the nutritional status of the adolescents of the seventh grade from the José María Heredia secondary school during 2009-2020. Group included 192 adolescents who with a previous consent of parents underwent anthropometric measurements (weight, height, waist circumference and estimation of the body mass index) and also the blood pressure and search of clinical signs of insulin resistance. A survey to parents on the family pathological backgrounds and on some data of their children was applied. Results: there was that the 20,31 percent of adolescents had excess weight or obesity, which was related in a significant way to the presence of a high blood pressure and clinical signs of insulin resistance. The high blood pressure was present in the 9,9 percent of adolescents without any relation to hereditary factors. Conclusions: obesity and body excess weight are a health problem in study adolescent population, which is associated with the presence of a high blood pressure and insulin resistance; there was not relation in its behavior to non-modifiable factors (family and personal pathological backgrounds)(AU)

[Food and Nutritional Surveillance System (SISVAN) in children from Rio Grande do Sul State, Brazil: coverage, nutritional status, and data reliability]. / Sistema de Vigilância Alimentar e Nutricional (SISVAN) em crianças do Rio Grande do Sul, Brasil: cobertura, estado nutricional e confiabilidade dos dados.

This study aimed to evaluate: the coverage of the Food and Nutritional Surveillance System (SISVAN) in the State of Rio Grande do Sul, Brazil, and it Regional Health Offices in 2006; the nutritional status of children 0-10 years of age; and the reliability of data on nutritional status recorded in the system. A cross-sectional descriptive study was conducted with secondary data on 63,320 children. Coverage was defined as the proportion of children younger than 10 years covered by the Family Health Strategy in the State's various municipalities (counties). Height-for-age (H/A) and body mass index for age (BMI/A) were classified according to World Health Organization (WHO) criteria. Agreement between the nutritional classifications recorded in the system and those calculated in this study was evaluated with the weighted kappa coefficient (at 5%). The system's coverage in the State of Rio Grande do Sul was 10.5%. Low height-for-age was found in 7.1% of children and overweight in 8.4%. Agreement between the classifications showed a kappa coefficient of 0.43. The system's coverage and agreement between classifications were both low, and the study showed the coexistence of high overweight and stunting rates in this age group.

Este estudo objetivou avaliar: cobertura do Sistema de Vigilância Alimentar e Nutricional (SISVAN) no Rio Grande do Sul e suas Coordenadorias Regionais de Saúde em 2006; estado nutricional das crianças de 0-10 anos e a confiabilidade dos dados sobre estado nutricional registradas no sistema. Realizou-se estudo transversal descritivo de base secundária com 63.320 crianças. A cobertura baseou-se no número de menores de 10 anos cobertos pela Estratégia Saúde da Família nos municípios. Os índices estatura/idade (E/I) e de massa corporal/idade (IMC/I) foram classificados com base na Organização Mundial da Saúde (OMS). A concordância entre classificações nutricionais registradas no sistema e as geradas neste estudo foi avaliada pelo teste kappa ponderado (nível de 5 por cento). No Rio Grande Sul, a cobertura do sistema foi de 10,5 por cento e encontraram-se frequências de déficit de E/I de 7,1 por cento e de excesso de peso de 8,4 por cento. A concordância entre classificações teve kappa = 0,43. Apontaram-se baixas cobertura do sistema e concordâncias de classificações e a coexistência de excesso de peso e déficit estatural entre os acompanhados.
