Resumo Este estudo objetivou avaliar a associação de fatores sociodemográficos e estilo de vida com consumo de alimentos in natura ou minimamente processados (INMP), ultraprocessados (AUP) e frutas e hortaliças. Trata-se de estudo transversal com 403 crianças de 4 a 7 anos de uma coorte retrospectiva. Variáveis sociodemográficas e estilo de vida foram investigadas através do questionário sociodemográfico. O consumo alimentar foi avaliado por três registros alimentares. Empregaram-se análises de regressão linear bivariadas e multivariadas para analisar as associações. Crianças com menor renda apresentaram maior consumo de alimentos INMP e menor consumo de AUP. Menor tempo de permanência na escola associou-se ao menor consumo de alimentos INMP e maior consumo de AUP. Crianças com maior tempo de tela e com pais de menor escolaridade, consumiram menos frutas e hortaliças. Fatores sociodemográficos desfavoráveis se associaram ao melhor perfil de consumo de alimentos segundo o nível de processamento, exceto para frutas e hortaliças. O maior tempo de permanência na escola e menor tempo de tela contribuíram para uma alimentação mais saudável.

Abstract The present study aimed to evaluate the association of sociodemographic factors and lifestyle with the consumption of in natura or minimally processed (INMP) foods, ultra-processed foods (UPFs), and fruits and vegetables. This was a cross-sectional study conducted with 403 children, aged 4 to 7 years, from a retrospective cohort. Sociodemographic and lifestyle variables were investigated using a sociodemographic questionnaire. Food consumption was assessed by three food records. Bivariate and multivariate linear regression analyses were used to analyze associations. Children with lower income had a higher consumption of INMP foods and a lower consumption of UPFs. A shorter time spent at school was associated with a lower consumption of INMP foods and a higher consumption of UPFs. Children with more screen time and less educated parents consumed less fruits and vegetables. Unfavorable sociodemographic factors were associated with a better profile of food consumption according to the level of processing, except for fruits and vegetables. The longer time spent at school and a shorter screen time contributed to a healthier diet.

Abstract Objectives: to investigate the association between the Índice de Qualidade da Dieta Adaptado para Gestantes (IQDAG) (Quality of Diet Index Adapted for Pregnant Women) with food consumption, lifestyle and health information. Methods: cross-sectional study with 110 pregnant women assisted at a public health service. Sociodemographic, nutritional and health data were collected from medical records. Food consumption was investigated through the usual intake, for a nutritional analysis, DietPro® program version 6.1 was used. Quality ofdiet was assessed using the IQDAG. Multinomial logistic regression was used to investigate an association between food consumption and IQDAG. Results: the average total score of the IQDAG was 61.3 (±26.1), this is the best quality of the diet. After adjusting for age, schooling and physical activity, the highest consumption of vitamin A (OR=1.04; CI95% = 1.02-1.07) and B2 (OR=2.63; CI95% = 1.19-5.70) was associated with a greater chance of having a better quality of diet (3rdtertile of the IQDAG). Conclusions: pregnant women with better quality of diet had higher intakes of vitamins A and B2. However, other population-based studies are suggested to more broadly in verify its association with food consumption and its ability to identify adherence to nutritional recommendations.

Resumo Objetivos: investigar a associação entre o Índice de Qualidade da Dieta Adaptado para Gestantes (IQDAG) com o consumo alimentar e hábitos de vida e informações de saúde. Métodos: estudo transversal com 110 gestantes atendidas em um serviço público de saúde. Os dados sociodemográficos, nutricionais e de saúde foram coletados a partir dos prontuários de atendimento. O consumo alimentar foi investigado por meio do recordatório de ingestão habitual, para a análise nutricional foi utilizado o Programa DietPro® versão 6.1. A qualidade da dieta foi avaliada utilizando o IQDAG. A regressão logística multinomial foi usada para investigar a associação entre o consumo alimentar e IQDAG. Resultados: a média da pontuação total do IQDAG foi 61,3 (±26,1), isto é uma melhor qualidade da dieta. Após ajuste por idade, escolaridade e atividade física, o maior consumo de vitamina A (OR=1,04; IC95%= 1,02-1,07) e B2 (OR= 2,63; IC95%= 1,19-5,70) esteve associado a maior chance da gestante apresentar uma melhor qualidade da dieta (3º tercil do IQDAG). Conclusões: gestantes com melhor qualidade da dieta tiveram maior ingestão das vitaminas A e B2. Entretanto, sugere-se outros estudos de base populacional para verificar de forma mais ampla sua associação com o consumo alimentar e sua capacidade de identificar a adesão as recomendações nutricionais.

RESUMO Objetivo: Caracterizar a situação de aleitamento materno e da adequação de prescrição de fórmulas infantis a lactentes assistidos por um programa de Atenção Secundária do Sistema Único de Saúde. Métodos: Trata-se de estudo transversal pela análise de prontuários de 350 lactentes de zero a 6 meses, acompanhados entre fevereiro a abril de 2019. Resultados: A possibilidade de aleitamento materno esteve presente em 97,0% das mães, e nenhum lactente apresentou condição médica aceitável para a proscrição do aleitamento materno. Apesar disso, apenas 47,2% dos casos estavam em aleitamento materno exclusivo antes do encaminhamento ao programa. Em relação aos motivos da introdução das fórmulas infantis, a complementação ao leite materno foi o mais presente (75,8%), seguido da volta da mãe ao mercado de trabalho (20,1%). As taxas gerais de inadequação dentre os prescritos foram de 65% antes da chegada ao programa, passando para 69% (fórmulas padrão) e 80% (fórmulas para fins especiais) durante o acompanhamento. Conclusão: A baixa taxa de aleitamento materno exclusivo e a prescrição indiscriminada de fórmulas infantis são preocupantes por causar prejuízos à saúde maternoinfantil e financeira do Sistema Único de Saúde.

ABSTRACT Objective: To characterize the situation of breastfeeding and the adequacy of prescription of infant formulas to infants assisted by a secondary care program of the Public Health System. Methods: This is a cross-sectional study with analysis of medical records of 350 infants from zero to 6 months, followed up between February to April 2019. Results: The possibility of breastfeeding was present in 97.0% of mothers and no infant presented an acceptable medical condition for proscription of breastfeeding. Despite this, only 47.2% of cases were on exclusive breastfeeding before being referred to the program. Regarding the reasons for the introduction of infant formulas, complementation to breast milk was the most present (75.8%), followed by mothers returning to the job market (20.1%). The general rates of inadequacy of those prescribed were 65% before arriving at the program, increasing to 69% (standard formulas) and 80% (formulas for special purposes) during follow-up. Conclusion: The low rate of exclusive breastfeeding and the indiscriminate prescription of infant formulas are a concern for damage to maternal-child healthcare and sound finances of the Public Health System.

ABSTRACT As pregnant women are susceptible to changes in iodine, which can cause miscarriage, goiter, thyroid nodules, hypothyroidism, in addition to fetal neurological impairment or development. The aim of this study was to verify the implications of the iodine alteration in each gestational trimester and its consequences of physiological justification. The review was based on PRISMA. Searching for articles that took place in March 2020 without delimiting data. As bases consulted were the Clinical Trials, Cochrane Library, Lilacs and Medline (PubMed). The descriptors were combined as follows: "pregnancy" AND "iodine deficiency". Articles that addressed iodine deficiency and its implications were included. The selection followed the steps of reading the titles, abstracts and full articles. To assess the methodological quality of the studies, the STROBE Instruction instrument was used. The research resulted in 1,266 studies and 11 were included. In assessing methodological quality, the lowest score was and the maximum 20. According to studies, the fourth most affected by iodine loss are the second and third, it is possible to increase the volume and pneumatic nodules, subclinical hypothyroidism, pre-eclampsia, among others. The damages caused by iodine deficiency in the first or second trimester are still reversible, therefore, they need to be diagnosed early, to guarantee an iodic homeostasis and prevent damage to the health of the mother-child binomial.

Abstract Objective: to identify cytokines and to associate them with several indexes of total and central adiposity in young female undergraduate students. Methods: 58 young female sophomore students, aged 18 to 25 years, from a Brazilian public university were evaluated. Both anthropometric measures (weight, height, waist circumference and hip circumference) and body composition were assessed through DXA, and the values of android, gynoid and truncal fat mass were obtained. Cytokines (IL-8, IL-1β, IL-6, IL-10 e TNF-α) were analyzed, and Body Mass Index (BMI), Body Adiposity Index (BAI), Visceral Adiposity Index (VAI), Conicity Index (CCI), Waist-Hip Index (WHR), Waist-to-Height Ratio (WHtR), Fat Mass Distribution Index 1 (FMI1) and Fat Mass Distribution Index 2 (FMI2) were calculated. Eventually, a linear regression was carried out to determine the regression coefficient and confidence interval (CI), having the predictor variables (cytokines) adjusted according to age and family history of obesity. The statistical significance of α = 5 % was applied. Results: a correlation between adiposity indexes and cytokines (CCI, WHR and IL-12; CCI, WHR, FMI1, FMI2and TNF-α) was identified. When it comes to the regression models, cytokines increase was related to CCI, WHR, FMI1 and FMI2 increase. Conclusion: pro-inflammatory cytokines were associated with an increase in adipose indexes. Therefore, these indexes became a feasible strategy for clinical practice in order to identify propensity to inflammatory disorders.

Resumen Objetivo: identificar citoquinas y asociarlas con los distintos índices de adiposidad total y central en estudiantes universitarias jóvenes. Métodos: se evaluaron 58 jóvenes estudiantes, de 18 a 25 años de edad, de segundo curso de carrera de una universidad pública brasileña. Se analizaron mediante densitometría (DEXA) tanto las medidas antropométricas (peso, talla, perímetro de la cintura y perímetro de la cadera) como la composición corporal, obteniéndose los valores de masa grasa androide, ginoide y troncal. Se analizaron las citoquinas (IL-8, IL-1β, IL-6, IL-10 y TNF-α) y se calcularon el índice de masa corporal (IMC), el índice de adiposidad corporal (IAC), el índice de adiposidad visceral (IAV), el índice de conicidad (CCI), el índice cintura-cadera (WHR), la ratio cintura-talla (WHtR), el índice de distribución de la masa grasa 1 (FMI1) y el índice de distribución de la masa grasa 2 (FMI2). Finalmente se realizó una regresión lineal para determinar el coeficiente de regresión y el intervalo de confianza (IC), ajustando las variables predictivas (citoquinas) a la edad y los antecedentes familiares de obesidad. Se aplicó una significación estadística de α = 5 %. Resultados: se detectó una correlación entre índices adiposos y citoquinas (CCI, WHR e IL-12; CCI, WHR, FMI1, FMI2 and TNF-α). Conforme a los modelos de regresión, el aumento de las citoquinas se relacionó con el aumento de CCI, WHR, FMI1 y FMI2. Conclusión: las citoquinas proinflamatorias se asociaron al aumento de los índices adiposos. Por tanto, los índices se convierten en una estrategia factible para detectar la propensión hacia los trastornos inflamatorios en la práctica clínica.

OBJECTIVES: To determine the prevalence of hypertension and associated factors in farmers in a rural region of Brazil. METHODS: A cross-sectional study was conducted involving a sample of 790 farmers who were residents of Espírito Santo, Brazil. RESULTS: The prevalence of hypertension was 35.8% (95%CI: 32.5-39.1%, n=283); however, it was higher in men (36.6%, n=151, p<0.001) and in those with excess weight (48.9%, n=197, p<0.001). Of the 283 hypertensive patients, 125 (44.2%) did not use antihypertensive drugs. In men, lower level of schooling (p=0.004), working in the field for fewer daily hours (p<0.001), and having greater abdominal adiposity (p=0.039) were associated with the presence of increased blood pressure. In women, age (p=0.002), lower schooling (p=0.021), and increased central adiposity (p=0.003) were independent predictors of blood pressure. CONCLUSION: The highest prevalence of hypertension was observed in men, with elevated blood pressure being strongly associated with social and economic factors. In women, the association with the classic factors (age, increase in abdominal adiposity, and low schooling) was stronger. In addition, most hypertensive patients are not adequately diagnosed or treated.

Resumo Este estudo teve como objetivo a investigação de alguns fatores que contribuíram para uma maior ou menor velocidade de crescimento de crianças até o sexto mês de vida. Estudo de coorte com 240 crianças, avaliadas em quatro momentos. Foram investigadas variáveis de nascimento, práticas alimentares da criança, dificuldade da mãe em amamentar e uso de chupeta. A velocidade de ganho de peso (gramas/dia) e ganho de comprimento (centímetros/mês) das crianças foi calculada em todas as avaliações e comparadas de acordo com as variáveis de interesse. No primeiro mês, a velocidade de ganho de peso das crianças nascidas de parto cesáreo foi menor. Até o segundo mês, a velocidade de crescimento (ganho de peso e comprimento) foi maior entre as crianças em aleitamento exclusivo ou predominante e menor entre as que consumiam fórmula infantil. Os filhos de mães que referiram dificuldade na amamentação apresentaram menor velocidade de crescimento até o segundo mês. As crianças com quatro meses que consumiam mingau apresentaram menores velocidade de ganho de peso e comprimento. O uso de chupeta esteve associado à menores velocidades de ganho de peso até o primeiro, segundo e quarto mês.

Abstract This study aimed to investigate some factors that contributed to higher or lower growth rate of children up to the sixth month of life. This is a cohort study with 240 children evaluated in four stages. Variables of birth, eating habits of the child, mothers’ breast-feeding difficulty and pacifier use were investigated. Children’s weight gain rate (grams/day) and size gain (cm/month) were measured in all assessments and compared according to the variables of interest. In the first month, weight gain rate of children born by cesarean section was smaller. By the second month, the growth rate (weight and size gain) was higher among children who were exclusively or predominantly breastfed and lower among those who consumed infant formula. Children of mothers who reported difficulty to breastfeed showed a lower growth rate until the second month. Children age four months who consumed porridge had lower weight and size gain rate. Pacifier use was associated with lower weight gain rates up the first, second and fourth month.

ResumoObjetivo:Avaliar a prevalência de deficiência de vitamina D e os fatores associados em mulheres e recém-nascidos no período pós-parto.Métodos:Estudo de delineamento transversal; avaliou-se a deficiência/insuficiência de vitamina D em 226 mulheres e seus recém-nascidos no município de Viçosa (MG), entre dezembro de 2011 e novembro de 2012. Coletaram-se 5mL de sangue do cordão umbilical e sangue venoso materno a fim de avaliar os parâmetros bioquímicos: vitamina D, fosfatase alcalina, cálcio, fósforo e paratormônio. Usou-se regressão de Poisson e adotou-se a Razão de Prevalência (95% IC), a fim de se avaliar a deficiência de vitamina D e fatores associados. Fez-se a análise de regressão linear múltipla para identificar os fatores associados à deficiência de 25(OH)D dos recém-nascidos e das mulheres do estudo. O critério para inclusão das variáveis na regressão linear múltipla foi a relação com a variável dependente na análise de regressão linear simples, considerando p<0,20. O nível de significância adotado foi α<5%.Resultados:Das 226 mulheres, 200 (88,5%) tinham entre 20 e 44 anos; a mediana foi de 28. Encontrou-se prevalência de níveis deficientes/insuficientes de vitamina D em 192 (85%) mulheres e 182 (80,5%) recém-nascidos. A 25(OH)D materna e a fosfatase alcalina materna se comportaram como preditores independentes da deficiência de vitamina D dos recém-nascidos.Conclusões:Foi possível identificar a alta prevalência de deficiência e insuficiência de vitamina D nas mulheres e recém-nascidos em nosso meio e a relação entre o estado nutricional materno de vitamina D e o do recém-nascido.

AbstractObjective:To assess the prevalence of vitamin D deficiency and its associated factors in women and their newborns in the postpartum period.Methods:This cross-sectional study evaluated vitamin D deficiency/insufficiency in 226 women and their newborns in Viçosa (Minas Gerais, BR) between December 2011 and November 2012. Cord blood and venous maternal blood were collected to evaluate the following biochemical parameters: vitamin D, alkaline phosphatase, calcium, phosphorus and parathyroid hormone. Poisson regression analysis, with a confidence interval of 95%, was applied to assess vitamin D deficiency and its associated factors. Multiple linear regression analysis was performed to identify factors associated with 25(OH)D deficiency in the newborns and women from the study. The criteria for variable inclusion in the multiple linear regression model was the association with the dependent variable in the simple linear regression analysis, considering p<0.20. Significance level was α<5%.Results:From 226 women included, 200 (88.5%) were 20-44 years old; the median age was 28 years. Deficient/insufficient levels of vitamin D were found in 192 (85%) women and in 182 (80.5%) neonates. The maternal 25(OH)D and alkaline phosphatase levels were independently associated with vitamin D deficiency in infants.Conclusions:This study identified a high prevalence of vitamin D deficiency and insufficiency in women and newborns and the association between maternal nutritional status of vitamin D and their infants' vitamin D status.
