RESUMEN
OBJECTIVE: To describe the prevalence of food poverty according to dimensions of socio-economic inequality and the food groups consumed by Brazilian children. DESIGN: Dietary data from a structured qualitative questionnaire collected by the Brazilian National Survey on Child Nutrition (ENANI-2019) were used. The new UNICEF indicator classified children who consumed 3-4 and <3 out of the eight food groups as living in moderate and severe food poverty, respectively. The prevalence of consumption of each food group and ultra-processed foods (UPF) was estimated by level of food poverty according to age categories (6-23; 24-59 months). The most frequent combinations of food groups consumed by children living in severe food poverty were calculated. Prevalence of levels of food poverty were explored according to socio-economic variables. SETTING: 123 municipalities of the five Brazilian macro-regions. PARTICIPANTS: 12 582 children aged 6-59 months. RESULTS: The prevalence of moderate and severe food poverty was 32·5 % (95 % CI 30·1, 34·9) and 6·0 % (95 % CI 5·0, 6·9), respectively. Children whose mother/caregiver had lower education (<8 years) and income levels (per capita minimum wage <») had the highest severe food poverty prevalence of 8·3 % (95 % CI 6·2, 10·4) and 7·5 % (95 % CI 5·6, 9·4), respectively. The most consumed food groups among children living in food poverty in all age categories were 'dairy products', 'grains, roots, tubers, and plantains' and 'ultra-processed foods'. CONCLUSION: Food poverty prevalence was high among Brazilian children. A significant occurrence of milk consumption associated with grains and a considerable prevalence of UPF consumption were found among those living in severe food poverty.

This study aimed to assess the prevalence and factors associated with lipid profile abnormalities of children aged 6 to 42 months in a Central-West Brazilian capital city. This cross-sectional study used data from the baseline of a cluster-randomized clinical trial conducted in parallel. It evaluated the lipid profile, usual nutrients intake (direct food-weighing method and 24-hour dietary recall), anthropometric parameters, and socioeconomic aspects of 169 children from early childhood education centers. Poisson regression with robust variance analysis was conducted. Of the total sample, 85% had dyslipidemia, 72% had high-density lipoproteins (HDL-c) levels below the desired range, 49% had increased triglycerides (TG), 17% exhibited elevated low-density lipoproteins (LDL-c), and 15% showed high total cholesterol (TC). An increase in the body mass index (BMI) for age z-score was associated with a higher prevalence of increased TG (PR = 1.22; 95%CI: 1.05-1.41; p = 0.009). Higher age in children was associated with an increased prevalence of high LDL-c (PR = 1.037; 95%CI: 1.01-1.07; p = 0.022) and TC (PR = 1.036; 95%CI: 1.00-1.07; p = 0.037), however it was a protective factor against low HDL-c (PR = 0.991; 95%CI: 0.98-1.00; p = 0.042). High energy intake was associated with low HDL-c (PR = 1.001; 95%CI: 1.00-1.00; p = 0.023). A higher prevalence of increased LDL-c (PR = 1.005; 95%CI: 1.00-1.01; p = 0.006) and decreased HDL-c (PR = 1.002; 95%CI: 1.00-1.00; p < 0.001) were associated with dietary cholesterol intake. Most of the children presented at least one alteration in serum lipids. Lipid profile abnormalities were associated with higher BMI, older age, and increased caloric and cholesterol intake.

BACKGROUND: Obesity is a chronic disease that increases the risk of cardiovascular diseases (CVD), including systemic arterial hypertension (SAH), underestimated in this population. The high mortality related to CVD reveals the need for early screening. One of the training tools is the waist-to-hip ratio (WHR). However, few studies evaluate its relationship with metabolic changes in severe obesity, making necessary a new cut-off point. METHOD: Cross-sectional study with 75 Brazilian women with severe obesity (mean age: 37,6 years; weight of 122 kg and body mass index (BMI) of 47,8 kg/m2). Height, weight, neck circumference (NC), hip (HC), waist (WC) and waist-to-hip ratio (WHR) were obtained. Blood samples were collected for lipid/glucose profile. The Receiver Operating Characteristic (ROC) was explored to define cut-off points for WHR based on SAH. Women were compared using the t-Student/Mann Whitney test. Pearson/Spearman correlations were performed, and the significance level was set at 5%. RESULTS: The ROC curve indicated that WHR ≥0.92 best predicted SAH. The group with WHR ≥0.92 had higher Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) (p = 0.037), insulin (p = 0.037), NC (p = 0.004), and Atherogenic Index of Plasma (AIP) (p = 0.038). WHR correlated with NC (p = 0.002; r = 0.358), glucose (p = 0.026; r = 0.270); insulin (p = 0.05; r = 0.238); HOMA-IR (p = 0.01; r = 0.3238), triglycerides (p = 0.006; r = 329) and AIP (p = 0.02; r = 0.370). CONCLUSIONS: A new cut-off point for WHR related to SAH in severe obesity is suggested.

BACKGROUND: Studies suggest an interplay between maternal metabolome and mental health. OBJECTIVE: We investigated the association of maternal serum metabolome at pregnancy with anxiety scores during pregnancy and throughout the first year postpartum. METHODS: A prospective cohort of Brazilian women collected 119 serum metabolome at pregnancy (28-38 weeks) and anxiety scores measured by the State-Trait Anxiety Inventory (STAI) at pregnancy (n = 118), 1 (n = 83), 6 (n = 68), and 12 (n = 57) months postpartum. Targeted metabolomics quantified metabolites belonging to amino acids (AA), biogenic amines/amino acid-related compounds, acylcarnitines, lysophosphatidylcholines, diacyl phosphatidylcholines, alkyl:acyl phosphatidylcholines, non-hydroxylated and hydroxylated sphingomyelins [SM(OH)], and hexoses classes. Linear mixed-effect models were used to evaluate the association of metabolites and STAI scores. Hierarchical clustering and principal component analyses were employed to identify clusters and metabolites, which drove their main differences. Multiple comparison-adjusted p-values (q-value) ≤ 0.05 were considered significant. RESULTS: AA (ß = -1.44) and SM(OH) (ß = -1.49) classes showed an association with STAI scores trajectory (q-value = 0.047). Two clusters were identified based on these classes. Women in cluster 2 had decreased AA and SM(OH) concentrations and higher STAI scores (worse symptoms) trajectory (ß = 2.28; p-value = 0.041). Isoleucine, leucine, valine, SM(OH) 22:1, 22:2, and 24:1 drove the main differences between the clusters. LIMITATIONS: The target semiquantitative metabolome analysis and small sample size limited our conclusions. CONCLUSIONS: Our results suggest that AA and SM(OH) during pregnancy play a role in anxiety symptoms throughout the first year postpartum.

Fe-deficiency anaemia is a major public health concern in children under 5 years of age. TMPRSS6 gene, encoding matriptase-2 protein, is implicated in Fe homoeostasis and has been associated with anaemia and Fe status in various populations. The aim of this cross-sectional study was to investigate the associations between the single nucleotide polymorphism (SNP) TMPRSS6 rs855791 and biomarkers of anaemia and Fe deficiency in Brazilian children attending day care centres. A total of 163 children aged 6-42 months were evaluated. Socio-economic, demographic, biochemical, haematological, immunological and genotype data were collected. Multiple logistic and linear regressions with hierarchical selection were used to assess the effects of independent variables on categorised outcomes and blood marker concentrations. Minor allele (T) frequency of rs855791 was 0·399. Each copy of the T allele was associated with a 4·49-fold increased risk of developing anaemia (P = 0·005) and a 4·23-fold increased risk of Fe deficiency assessed by serum soluble transferrin receptor (sTfR) (P < 0·001). The dose of the T allele was associated with an increase of 0·18 mg/l in sTfR concentrations and reductions of 1·41 fl and 0·52 pg in mean corpuscular volume (MCV) and mean corpuscular haemoglobin (MCH), respectively. In conclusion, the T allele of SNP TMPRSS6 rs855791 was significantly associated with anaemia and Fe deficiency assessed by sTfR in Brazilian children attending day care centres. The effect was dose dependent, with each copy of the T allele being associated with lower MCV and MCH and higher concentrations of sTfR.

O objetivo deste estudo foi avaliar a prevalência e os fatores associados às anormalidades do perfil lipídico de crianças de 6 a 42 meses de idade em uma capital do Centro-oeste do Brasil. Este estudo transversal utilizou dados da linha de base de um ensaio clínico randomizado por conglomerados realizado em paralelo. Avaliou-se o perfil lipídico, a ingestão habitual de nutrientes (método de pesagem direta de alimentos e recordatório alimentar de 24 horas), parâmetros antropométricos e aspectos socioeconômicos de 169 crianças de centros de educação infantil. Foi realizada uma regressão de Poisson com análise de variância robusta. Da amostra total, 85% apresentavam dislipidemia, 72% tinham níveis de lipoproteínas de alta densidade (HDL-c) abaixo da faixa desejada, 49% tinham triglicerídeos (TG) aumentados, 17% apresentavam lipoproteínas de baixa densidade (LDL-c) elevadas e 15% apresentavam colesterol total (CT) elevado. Um aumento no índice de massa corporal (IMC) para o escore z da idade foi associado a uma maior prevalência de aumento de TG (RP = 1,22; IC95%: 1,05-1,41; p = 0,009). A idade mais avançada das crianças foi associada a uma maior prevalência de LDL-c alto (RP = 1,037; IC95%: 1,01-1,07; p = 0,022) e CT (RP = 1,036; IC95%: 1,00-1,07; p = 0,037), mas foi um fator de proteção contra HDL-c baixo (RP = 0,991; IC95%: 0,98-1,00; p = 0,042). A alta ingestão de energia foi associada ao baixo HDL-c (RP = 1,001; IC95%: 1,00-1,00; p = 0,023). Uma maior prevalência de aumento de LDL-c (RP = 1,005; IC95%: 1,00-1,01; p = 0,006) e diminuição de HDL-c (RP = 1,002; IC95%: 1,00-1,00; p < 0,001) foi associada à ingestão de colesterol na dieta. A maioria das crianças apresentou pelo menos uma alteração nos lipídios séricos. As anormalidades do perfil lipídico foram associadas ao IMC mais alto, à idade mais avançada e ao aumento da ingestão calórica e de colesterol.

RESUMEN
The objective of this study was to describe the frequency of cross-breastfeeding, human milk donation to human milk banks and reception of human milk from human milk banks, and to investigate the intersection between cross-breastfeeding and breast milk donation practices. This study used data from the national household-based survey Brazilian National Survey on Child Nutrition (ENANI-2019), which collected information from 14,558 children < 5 years old between February 2019 and March 2020. The present study included data from 5,831 biological mothers who reported having breastfed their child < 2 years old at least once and replied questions about cross-breastfeeding, donation and recaption of human milk to human milk banks. Prevalence and 95% confidence intervals (95%CI) were estimated for each stratifier, considering the study complex sample design. Among mothers of children < 2 years old who breastfed their child at least once, 21.1% practiced cross-breastfeeding; breastfeeding another child was more frequent (15.6%) than allowing a child to be breastfed by another woman (11.2%). Among this population, 4.8% of women donated human milk to a human milk bank, and 3.6% reported that their children had received donated human milk. The donation of human milk is a practice recommended by the Brazilian Ministry of Health and has the potential to save thousands of newborns throughout Brazil. In contrast, cross-breastfeeding is contraindicated due to the potential risk of transmitting HIV. There is a need for a broad debate on these practices in Brazil and worldwide.

Factors associated with anemia and vitamin A deficiency were investigated in 7,716 children 6-59 months of age studied in the Brazilian National Survey on Child Nutrition (ENANI-2019). We adopted a hierarchical approach based on a United Nations Children's Fund (UNICEF) theoretical model with three levels, stratifying by age (6-23; 24-59 months). Prevalence ratio (PR) and 95% confidence interval (95%CI) were estimated. Enabling determinants: a higher prevalence of anemia was observed in children 6-23 months whose mothers had ≤ 7 years of schooling (PR = 1.92; 95%CI: 1.10; 3.34), < 20 years old (PR = 2.47; 95%CI: 1.34; 4.56) or 20-30 years old (PR = 1.95; 95%CI: 1.11; 3.44), mixed-race (PR = 1.57; 95%CI: 1.06; 2.23); and in children 24-59 months in the North Region (PR = 3.11; 95%CI: 1.58; 6.13). A higher prevalence for vitamin A deficiency was observed in children 6-23 months from Central-West (PR = 2.32; 95%CI: 1.33; 4.05), and in children 24-59 months living in the North (PR = 1.96; 95%CI: 1.16; 3.30), South (PR = 3.07; 95%CI: 1.89; 5.01), and Central-West (PR = 1.91; 95%CI: 1.12; 3.25) and whose mothers were 20-34 years (PR = 1.62; 95%CI: 1.11; 2.35). Underlying determinants: the presence of more than one child < 5 years old in the household was associated with a higher prevalence of anemia (PR = 1.61; 95%CI: 1.15; 2.25) and vitamin A deficiency (PR = 1.82; 95%CI: 1.09; 3.05) in children 6-23 months. Immediate determinants: consumption of 1-2 groups of ultra-processed foods in children 24-59 months (PR = 0.44; 95%CI: 0.25; 0.81) and lack of breastfeeding in the day before in children 6-23 months (PR = 0.56; 95%CI: 0.36; 0.95) were associated with lower prevalence of anemia and vitamin A deficiency. Public policies focused on geographically and socially vulnerable groups are needed to promote equity.

Introduction: Evaluating the food consumption of school-aged children is crucial to monitor their dietary habits, promote targeted interventions, and contribute public policies that aimed healthy eating. In this context, our objective was to develop and validate the Illustrated Questionnaire on Food Consumption for Brazilian Schoolchildren (QUACEB) of 6 to 10 years old, which is a self-reported illustrated recall. Methods: Validity was obtained in four stages as follows: selection of foods, validation of items, validation of illustrations, and pretest. Foods were selected by considering the data from the main surveys that have been conducted with the Brazilian population and schoolchildren in recent years, the degree of food processing, and the main foods from each of the country's five macroregions. The content of the items was validated by comparing the children's and their parent's responses. For this, the questionnaire was published in an online format, and 6- to 10-year-old elementary schoolchildren were recruited using the snowball technique. The first part of the questionnaire was answered by the parent after the child's lunch, and the second was completed by the child the following day. Thirty-two parent and child dyads participated. Sensitivity, specificity, area under the curve (AUC), and kappa (k) tests were performed. Results: Of the 30 foods presented on the questionnaire, 15 were reported as consumed. High sensitivity (mean of 88.5%), high specificity (average of 92.0%), substantial agreement (k = 0.78), low disagreement (6.2%), and AUC of 0.90 were found. The illustrations were validated in a focus group with fourth-grade children from a school chosen for convenience. The food illustrations were designed for children, who were asked to name the food. Eighteen children participated and verified that the images were representative of the foods. In the pretest, three schools were chosen for convenience that announced the link to the online questionnaire in WhatsApp groups of parents with students from first to fifth grade. Fifteen children answered the questionnaire and 86.7% (n = 13) judged it excellent or good. Conclusion: Thus, the food consumption questionnaire is valid for elementary schoolchildren of 6 to 10 years old and can be applied in research to assess the dietary patterns of children in Brazil.

The study aimed to estimate the prevalence of minimum dietary diversity (MDD) and consumption of ultra-processed foods in children 6-23 months of age according to sociodemographic variables. Three indicators of complementary feeding of 4,354 children from the Brazilian National Survey on Child Nutrition (ENANI-2019) were built based on a questionnaire about food consumption on the day before the interview: MDD, consumption of ultra-processed foods, and MDD without the consumption of ultra-processed foods. The prevalence and 95%CI were calculated, stratified by macroregion; race/skin color, education and work status of the mother or caregiver; enrollment in the Brazilian Income Transfer Program; household food security; sanitation; and child enrollment in daycare/school. The overall prevalence of MDD was 63.4%, with lower prevalences among children who lived in the North Region (54.8%), whose mothers or caregivers had 0-7 years of education (50.6%), and lived under moderate or severe food insecurity (52.6%). Ultra-processed foods were consumed by 80.5% of the children, with the highest prevalence in the North Region (84.5%). The prevalence of MDD without ultra-processed foods was 8.4% and less prevalent among children with black mothers or caregivers (3.6%) and among those whose mother or caregiver had 8-10 years of education (3.6%). The most frequently consumed food groups from the MDD indicator were grains, roots and tubers (90.2%), dairy products (81%) and those from ultra-processed food were sweet or salty cookies/crackers (51.3%) and instant flours (41.4%). The ubiquitous presence of ultra-processed foods in the diets of Brazilian children and the low frequency of diversified foods, especially among the most vulnerable populations, indicate the need to strengthen policies and programs to ensure adequate and healthy infant nutrition.

This manuscript aims to report the nutrition transition in Brazilian children under 5 years old from 2006 to 2019. Microdata from the Brazilian National Survey on Demography and Health of Women and Children (PNDS 2006) and the Brazilian National Survey on Child Nutrition (ENANI-2019) were analyzed. The indicators considered were: micronutrient status (anemia and vitamin A deficiency), anthropometric status (stunting and excessive weight), and breastfeeding practice (exclusive breastfeeding among children < 6 months and continued breastfeeding among children 12-23 months). We also analyzed minimum dietary diversity (MDD), consumption of ultra-processed foods, consumption of meat or eggs, and not consuming fruits or vegetables in children 6-59 months of age only for ENANI-2019. Equiplot charts were generated according to geographic region, maternal schooling level, and maternal race/skin color. From 2006 to 2019, the prevalence rates of anemia and vitamin A deficiency decreased from 20.5% to 10.1% and 17.2% to 6%, respectively. The prevalence of stunting remained at 7%, and excessive weight rates increased from 6% to 10.1%. The prevalence of exclusive breastfeeding among children < 6 months increased from 38.6% to 45.8%, and of continued breastfeeding among children 12-23 months from 34.6% to 43.6%. In 2019, 61.5% of children achieved the MDD, 88.8% consumed ultra-processed foods, 83.1% consumed meat or egg, and 25.7% did not consume fruits or vegetables the day before the survey. Trends of decreased micronutrient deficiencies, increased breastfeeding, and excessive weight rates, as well as reductions in disparities related to geographic region, maternal schooling level, and maternal race/skin color, were observed for most of the indicators.

BACKGROUND: The comprehension of breastfeeding patterns and trends through comparable indicators is essential to plan and implement public health policies. OBJECTIVE: To evaluate the trends of breastfeeding indicators in Brazil from 1996 to 2019 and estimate the gap to achieve the WHO/UNICEF 2030 targets in children under 5 years. METHODS: Microdata from two National Surveys on Demography and Health of Women and Children (PNDS-1996 and PNDS-2006) and the Brazilian National Survey on Child Nutrition-2019 were used. The indicators of early initiation of breastfeeding (EIBF), exclusive breastfeeding of infants 0-5 months of age (EBF<6 mo), continued breastfeeding at 1 year of age (CBF1yr) and CBF at 2 years of age (CBF2yr) were analysed using prevalence and 95% CI. The average annual variation and years to achieve the WHO/UNICEF 2030 targets were calculated for Brazil and the macroregions. Statistical analyses considered the survey's complex sample design for each database. RESULTS: EIBF increased from 36.3% (95% CI 33.6% to 39.0%) in 1996 to 60.9% (95% CI 56.5% to 65.3%) in 2006 (statistically significant) and 62.5% (95% CI 58.3% to 66.6%) in 2019. EBF<6 mo increased from 26.9% (95% CI 21.3% to 31.9%) in 1996 to 39.0% (95% CI 31.0% to 47.1%) in 2006 and 45.8% (95% CI 40.9% to 50.7%) in 2019 (significant increases for 1996-2019 for Brazil, Northeast and Midwest regions). CBF1yr rose from 36.6% (95% CI 30.8% to 42.4%) in 1996 to 48.7% (95% CI 38.3% to 59.0%) in 2006, and 52.1% (95% CI 45.4% to 58.9%) in 2019. CBF2yr increased from 24.7% (95% CI 19.5% to 29.9%) in 1996 to 24.6% (95% CI 15.7% to 33.5%) in 2006 and 35.5% (95% CI 30.4% to 40.6%) in 2019 (significant increase for 1996-2019). The South and Southeast regions need to double the 2019 prevalence to reach the target for the CBF1yr and CBF2yr; the Northeast and North need to increase 60% the current prevalence for the indicator of EBF<6 mo. CONCLUSION: A substantial improvement in breastfeeding indicators occurred in Brazil from 1996 to 2019, although at an insufficient rate to achieve the WHO/UNICEF 2030 targets.

This study aimed to characterize micronutrient supplements use among Brazilian children 6-59 months of age included in the Brazilian National Survey on Child Nutrition (ENANI-2019; n = 12,598). Micronutrient supplements use at the time of the interview and the 6 months prior to it was evaluated using a structured questionnaire. The following indicators were included: micronutrient supplement use; supplements containing a single micronutrient; supplements of the Brazilian National Iron Supplementation Program (PNSF); multivitamin supplements with or without minerals; multivitamin supplements with minerals; multivitamin supplements without minerals. The estimates and their respective 95% confidence intervals (95%CI) were calculated for Brazil and according to macroregion, educational level of the mother or caregiver, and type of health care service used, considering the sampling plan, weights, and calibration. In Brazil, the prevalence of micronutrient supplements use was 54.2% (95%CI: 50.5; 57.8), with the highest prevalence in the North Region (80.2%; 95%CI: 74.9; 85.6) and among children 6-23 months of age (69.5%; 95%CI: 65.7; 73.3). The prevalence of the use of supplements containing exclusively iron and exclusively vitamin A in Brazil was 14.6% (95%CI: 13.1; 16.1) and 23.3% (95%CI: 19.4; 27.1), respectively. The prevalence of the use of multivitamin with or without minerals in Brazilian children 6-59 months of age was 24.3% (95%CI: 21.4; 27.2). These results may help to understand the practice of supplements use among Brazilian children and support the proposal of national public policies for the prevention and control of micronutrient deficiencies.

RESUMEN
ABSTRACT Objective: This study aimed to evaluate the effect of baru nuts supplementation on body composition and metabolic profile in adults with type 2 diabetes. Methods: This is a randomized, placebo-controlled, crossover trial with 30 adults with type 2 diabetes. The assay had two periods of 12 weeks each, with a washout period of 12 weeks between treatments. The subjects were randomized and received the two treatments in alternate periods: supplementation of 30g baru nuts or placebo. Anthropometry, body composition, blood pressure, blood sampling, food intake, and physical activity data were analyzed. Results: Baru nut intake reduced waist circumference (p=0.032), compared to placebo group. In the intra-group analysis, baru nut intake reduced total cholesterol (p=0.012) and LDL-c (p=0.017). Conclusion: The daily intake of baru nuts improved abdominal adiposity. Therefore, these nuts should be included in the diet to improve the health status of adults with type 2 diabetes.

Abstract: Factors associated with anemia and vitamin A deficiency were investigated in 7,716 children 6-59 months of age studied in the Brazilian National Survey on Child Nutrition (ENANI-2019). We adopted a hierarchical approach based on a United Nations Children's Fund (UNICEF) theoretical model with three levels, stratifying by age (6-23; 24-59 months). Prevalence ratio (PR) and 95% confidence interval (95%CI) were estimated. Enabling determinants: a higher prevalence of anemia was observed in children 6-23 months whose mothers had ≤ 7 years of schooling (PR = 1.92; 95%CI: 1.10; 3.34), < 20 years old (PR = 2.47; 95%CI: 1.34; 4.56) or 20-30 years old (PR = 1.95; 95%CI: 1.11; 3.44), mixed-race (PR = 1.57; 95%CI: 1.06; 2.23); and in children 24-59 months in the North Region (PR = 3.11; 95%CI: 1.58; 6.13). A higher prevalence for vitamin A deficiency was observed in children 6-23 months from Central-West (PR = 2.32; 95%CI: 1.33; 4.05), and in children 24-59 months living in the North (PR = 1.96; 95%CI: 1.16; 3.30), South (PR = 3.07; 95%CI: 1.89; 5.01), and Central-West (PR = 1.91; 95%CI: 1.12; 3.25) and whose mothers were 20-34 years (PR = 1.62; 95%CI: 1.11; 2.35). Underlying determinants: the presence of more than one child < 5 years old in the household was associated with a higher prevalence of anemia (PR = 1.61; 95%CI: 1.15; 2.25) and vitamin A deficiency (PR = 1.82; 95%CI: 1.09; 3.05) in children 6-23 months. Immediate determinants: consumption of 1-2 groups of ultra-processed foods in children 24-59 months (PR = 0.44; 95%CI: 0.25; 0.81) and lack of breastfeeding in the day before in children 6-23 months (PR = 0.56; 95%CI: 0.36; 0.95) were associated with lower prevalence of anemia and vitamin A deficiency. Public policies focused on geographically and socially vulnerable groups are needed to promote equity.
Resumo: Fatores associados a anemia e deficiência de vitamina A foram investigados em 7.716 crianças de 6-59 meses de idade parte da Estudo Nacional de Alimentação e Nutrição Infantil (ENANI-2019). Adotamos uma abordagem hierárquica baseada em um modelo teórico do Fundo das Nações Unidas para a Infância (UNICEF) com três níveis estratificados por idade (6-23; 24-59 meses). Foram estimadas razões de prevalência (RP) e intervalos de 95% de confiança (IC95%). Determinantes habilitadores: observamos maior prevalência de anemia em crianças de 6-23 meses de idade cujas mães tinham ≤ 7 anos de escolaridade (RP = 1,92; IC95%: 1,10; 3,34), < 20 anos de idade (RP = 2,47; IC95%: 1,34; 4,56) ou 20-30 anos de idade (RP = 1,95; IC95%: 1,11; 3,44), cor parda (RP = 1,57; IC95%: 1,06; 2,23); e em crianças de 24-59 meses de idade na Região Norte (RP = 3,11; IC95%: 1,58; 6,13). Encontramos maior prevalência de deficiência de vitamina A em crianças de 6-23 meses de idade no Centro-oeste (RP = 2,32; IC95%: 1,33; 4,05) e em crianças de 24-59 meses de idade residentes nas regiões Norte (RP = 1,96; IC95%: 1,16; 3,30), Sul (RP = 3,07; IC95%: 1,89; 5,01) e Centro-oeste (RP = 1,91; IC95%: 1,12; 3,25) cujas mães tinham entre 20-34 anos de idade (RP = 1,62; IC95%: 1,11; 2,35). Determinantes subjacentes: a presença de mais de uma criança < 5 anos de idade no domicílio se associou a maior prevalência de anemia (RP = 1,61; IC95%: 1,15; 2,25) e deficiência de vitamina A (RP = 1,82; IC95%: 1,09; 3,05) em crianças de 6-23 meses de idade. Determinantes imediatos: o consumo de 1-2 grupos de alimentos ultraprocessados em crianças de 24-59 meses de idade (RP = 0,44; IC95%: 0,25; 0,81) e o não aleitamento materno no dia anterior em crianças de 6-23 meses de idade (RP = 0,56; IC95%: 0,36; 0,95) foram associados com a menor prevalência de anemia e deficiência de vitamina A. Políticas públicas focadas em grupos geográfica e socialmente vulneráveis são necessárias para promover equidade.

RESUMEN
Abstract: The objective of this study was to describe the frequency of cross-breastfeeding, human milk donation to human milk banks and reception of human milk from human milk banks, and to investigate the intersection between cross-breastfeeding and breast milk donation practices. This study used data from the national household-based survey Brazilian National Survey on Child Nutrition (ENANI-2019), which collected information from 14,558 children < 5 years old between February 2019 and March 2020. The present study included data from 5,831 biological mothers who reported having breastfed their child < 2 years old at least once and replied questions about cross-breastfeeding, donation and recaption of human milk to human milk banks. Prevalence and 95% confidence intervals (95%CI) were estimated for each stratifier, considering the study complex sample design. Among mothers of children < 2 years old who breastfed their child at least once, 21.1% practiced cross-breastfeeding; breastfeeding another child was more frequent (15.6%) than allowing a child to be breastfed by another woman (11.2%). Among this population, 4.8% of women donated human milk to a human milk bank, and 3.6% reported that their children had received donated human milk. The donation of human milk is a practice recommended by the Brazilian Ministry of Health and has the potential to save thousands of newborns throughout Brazil. In contrast, cross-breastfeeding is contraindicated due to the potential risk of transmitting HIV. There is a need for a broad debate on these practices in Brazil and worldwide.
Resumo: O objetivo deste estudo foi descrever a frequência de amamentação cruzada, doação de leite humano para bancos de leite humano e recepção de leite humano dos bancos de leite humano, além de investigar a interseção entre práticas de amamentação cruzada e a doação de leite materno. Este estudo utilizou dados do Estudo Nacional de Alimentação e Nutrição Infantil (ENANI-2019), uma pesquisa populacional de base domiciliar que coletou informações de 14.558 crianças < 5 anos entre fevereiro de 2019 e março de 2020. Dados de 5.831 mães biológicas que relataram ter amamentado seu filho com menos de dois anos de idade pelo menos uma vez e que responderam às perguntas sobre amamentação cruzada, doação e recepção de leite humano nos bancos de leite humano foram inclusos. Foram estimados as prevalências e os intervalos de 95% de confiança (IC95%) para cada estratificador, considerando o desenho amostral complexo do estudo. Entre as mães de crianças com menos de dois anos que amamentaram o filho pelo menos uma vez, 21,1% praticaram a amamentação cruzada. Amamentar outra criança foi mais frequente (15,6%) do que permitir que a sua criança fosse amamentada por outra mulher (11,2%). Entre essas mulheres, 4,8% doaram leite humano para um bancos de leite humano e 3,6% relataram que seus filhos receberam leite humano doado. A doação de leite humano é uma prática recomendada pelo Ministério da Saúde e tem o potencial de salvar milhares de recém-nascidos em todo o Brasil. Em contraste, a amamentação cruzada é contraindicada devido ao risco potencial de transmissão do HIV. Há necessidade de um amplo debate sobre essas práticas no Brasil e no mundo.
Resumen: El objetivo de este estudio fue describir la frecuencia de lactancia materna cruzada, la donación de leche humana a los bancos de leche humana y la recepción de leche humana de los bancos de leche humana, además de investigar la intersección entre las prácticas de lactancia materna cruzada y la donación de leche materna. Este estudio utilizó datos del Estudio Nacional de Alimentación y Nutrición Infantil (ENANI-2019), una encuesta nacional de hogares que recopiló información de 14.558 niños < 5 años, en el periodo entre febrero de 2019 y marzo de 2020. Se incluyeron datos de 5.831 madres biológicas que reportaron haber amamantado a su hijo < 2 años, al menos una vez, y que respondieron preguntas sobre lactancia cruzada, donación y recepción de leche humana en los bancos de leche humana. Se estimaron prevalencias y los intervalos de 95% de confianza (IC95%) para cada estrato, considerando el diseño muestral complejo del estudio. Entre las madres de niños < 2 años que amamantaron a su hijo al menos una vez, el 21,1% practicaba la lactancia cruzada. Amamantar a otro hijo fue más frecuente (15,6%) que dejar que su hijo sea amamantado por otra mujer (11,2%). Entre estas mujeres, el 4,8% donó leche humana a un bancos de leche humana y el 3,6% informó que sus hijos recibieron leche humana donada. La donación de leche humana es una práctica recomendada por el Ministerio de Salud brasileño y puede salvar muchos recién nacidos en todo Brasil. Por el contrario, la lactancia cruzada está contraindicada debido al potencial riesgo de transmisión del VIH. Es necesario un amplio debate sobre estas prácticas en Brasil y en el mundo.
RESUMEN
Abstract: The study aimed to estimate the prevalence of minimum dietary diversity (MDD) and consumption of ultra-processed foods in children 6-23 months of age according to sociodemographic variables. Three indicators of complementary feeding of 4,354 children from the Brazilian National Survey on Child Nutrition (ENANI-2019) were built based on a questionnaire about food consumption on the day before the interview: MDD, consumption of ultra-processed foods, and MDD without the consumption of ultra-processed foods. The prevalence and 95%CI were calculated, stratified by macroregion; race/skin color, education and work status of the mother or caregiver; enrollment in the Brazilian Income Transfer Program; household food security; sanitation; and child enrollment in daycare/school. The overall prevalence of MDD was 63.4%, with lower prevalences among children who lived in the North Region (54.8%), whose mothers or caregivers had 0-7 years of education (50.6%), and lived under moderate or severe food insecurity (52.6%). Ultra-processed foods were consumed by 80.5% of the children, with the highest prevalence in the North Region (84.5%). The prevalence of MDD without ultra-processed foods was 8.4% and less prevalent among children with black mothers or caregivers (3.6%) and among those whose mother or caregiver had 8-10 years of education (3.6%). The most frequently consumed food groups from the MDD indicator were grains, roots and tubers (90.2%), dairy products (81%) and those from ultra-processed food were sweet or salty cookies/crackers (51.3%) and instant flours (41.4%). The ubiquitous presence of ultra-processed foods in the diets of Brazilian children and the low frequency of diversified foods, especially among the most vulnerable populations, indicate the need to strengthen policies and programs to ensure adequate and healthy infant nutrition.
Resumo: O objetivo do estudo foi estimar a prevalência de diversidade alimentar mínima (DAM) e consumo de alimentos ultraprocessados em crianças de 6-23 meses de acordo com variáveis sociodemográficas. Três indicadores de alimentação complementar de 4.354 crianças do Estudo Nacional de Alimentação e Nutrição Infantil (ENANI-2019) foram construídos com base em um questionário sobre o consumo alimentar do dia anterior à entrevista: DAM, consumo de alimentos ultraprocessados e DAM sem consumo de alimentos ultraprocessados. Foram calculadas as prevalências e IC95%, estratificados por macrorregião; raça/cor da pele, escolaridade e situação profissional da mãe ou cuidador; inscrição no Programa Bolsa Família; segurança alimentar do domicílio; saneamento; e matrícula da criança em creche/escola. A prevalência geral de DAM foi de 63,4%, com menores prevalências entre crianças que residiam na Região Norte (54,8%), cujas maẽs ou cuidadores tinham de 0-7 anos de estudo (50,6%) e entre aquelas que viviam em situação de insegurança alimentar moderada ou grave (52,6%). Os alimentos ultraprocessados foram consumidos por 80,5% das crianças, com maior prevalência na Região Norte (84,5%). A prevalência de DAM sem alimentos ultraprocessados foi de 8,4%, sendo menos prevalente entre crianças cuja mãe ou cuidador era negro (3,6%) e entre aquelas cuja mãe ou cuidador tinha 8-10 anos de estudo (3,6%). Os grupos de alimentos do indicador DAM mais consumidos foram os cereais, raizes e tubérculos (90,2%), os derivados do leite (81%) e os dos alimentos ultraprocessados foram os biscoitos (51,3%) e os cereais instantâneos (41,4%). A onipresença de alimentos ultraprocessados na alimentação das crianças brasileiras e a baixa frequência de diversidade alimentar, especialmente entre as populações mais vulneráveis, indicam a necessidade de fortalecer políticas e programas para garantir uma nutrição infantil adequada e saudável.
Resumen: El objetivo del estudio fue estimar la prevalencia de diversidad alimentaria mínima (DDM) y consumo de alimentos ultraprocesados en niños de 6-23 meses según variables sociodemográficas. Se construyeron tres indicadores de alimentación complementaria de 4.354 niños de el Estudio Nacional de Alimentación y Nutrición Infantil (ENANI-2019) a partir de un cuestionario sobre el consumo de alimentos el día anterior a la entrevista: DDM, consumo de alimentos ultraprocesados y DDM sin consumo de alimentos ultraprocesados. Se calcularon la prevalencia y los IC95%, estratificados por macrorregión; raza/color de piel, situación educativa y laboral de la madre o cuidador; inscripción al Programa Bolsa Familia; seguridad alimentaria del hogar; saneamiento; e inscripción de niños en guarderías/escuelas. La prevalencia general de DDM fue del 63,4%, con prevalencias menores entre los niños que vivían en la Región Norte (54,8%), cuyas madres o cuidadores tenían entre 0-7 años de escolaridad (50.6%) y los que vivían en inseguridad alimentaria moderada o grave (52,6%). Los alimentos ultraprocesados fueron consumidos por el 80,5% de los niños, con mayor prevalencia en la Región Norte (84,5%). La prevalencia de DDM sin alimentos ultraprocesados fue del 8,4%, siendo menos prevalente entre niños de padres negros (3,6%) y con 8-10 años de escolaridad (3,6%). Los grupos de alimentos más consumidos del indicador DDM fueron los granos, raíces y tubérculos (90,2%), y los productos lácteos (81%) y los de alimentos ultraprocesados fueron las galletas (51,3%) y los cereales instantáneos (41,4%). La presencia ubicua de alimentos ultraprocesados en las dietas de los niños brasileños y la baja frecuencia diversidad dietética, especialmente entre las poblaciones más vulnerables, indican la necesidad de fortalecer políticas y programas para garantizar una nutrición infantil adecuada y saludable.
RESUMEN
Estratégias inovadoras precisam ser adotadas para o combate à crescente prevalência de obesidade. Assim, o objetivo desse trabalho é avaliar o efeito de uma ação de aconselhamento nutricional com uso de rede social no enfrentamento à obesidade. Este é um estudo experimental do tipo antes e depois, incluindo 60 indivíduos com excesso de peso e adscritos a uma Unidade Básica de Saúde. Foi realizado de junho-outubro de 2020. As ações educativas (compartilhamento de informações sobre alimentação saudável e saúde e pactuação de desafios) foram realizadas pelo aplicativo WhatsApp®, semanalmente, por 16 semanas. Foram coletadas informações sociodemográficas, econômicas, clínicas, antropométricas, sobre consumo alimentar e exames bioquímicos. Os dados foram comparados por teste de Wilcoxon ou Kappa. A maioria dos participantes era do sexo feminino e 36,4% com diagnóstico de hipertensão. Após a intervenção, verificou-se redução de circunferência da cintura (antes:107,3±11,4; depois:105,6±11,5 cm, p=0,004), colesterol total (antes:205,9±48,3; depois:191,5±34,3 mg/dL, p<0,001) e LDL-c (antes:132,4±37,8; depois:120,2±29,3 mg/dL, p<0,001). A ação foi capaz de promover reduções de marcadores corporais de obesidade e de descompensações metabólicas associadas a obesidade, demonstrando a importância de intervenções inovadoras que possam somar a outras intervenções e facilitar a adesão do público.
Innovative strategies need to be adopted to combat the growing prevalence of obesity. Thus, the aim of this study is to evaluate the effect of a nutritional counseling activity using a social network in coping with obesity. This is a before-and-after experimental study, including 60 overweight individuals enrolled in a Primary Care Center. It was carried out from June to October 2020. Educational actions (sharing information about healthy eating and health and agreeing on challenges) were carried out through the WhatsApp® application, weekly, for 16 weeks. Sociodemographic, economic, clinical, anthropometric, food consumption, and biochemical data were collected. Data were compared by the Wilcoxon or Kappa test. Most participants were female and 36.4% had a diagnosis of hypertension. After the intervention, there was a reduction in waist circumference (before:107.3±11.4; after:105.6±11.5 cm, p=0.004), total cholesterol (before:205.9±48, 3; after:191.5±34.3 mg/dL, p<0.001), and LDL-c (before:132.4±37.8; after:120.2±29.3 mg/dL, p<0.001). The activity was able to promote reductions in body markers of obesity and metabolic imbalances associated with obesity, demonstrating the importance of innovative interventions that can add to other interventions and facilitate public adherence.
