This manuscript aims to report the nutrition transition in Brazilian children under 5 years old from 2006 2019. Microdata National Survey on Demography and Health of Women Children (PNDS 2006) Child Nutrition (ENANI-2019) were analyzed. The indicators considered were: micronutrient status (anemia vitamin A deficiency), anthropometric (stunting excessive weight), breastfeeding practice (exclusive among < 6 months continued 12-23 months). We also analyzed minimum dietary diversity (MDD),...
Abstract: This article aims to present general methodological aspects of the Brazilian National Survey on Child Nutrition (ENANI-2019), from conception study design details data collection. is a household-based population survey with sample calculated at 15,000 households identify children under five years age, conducted in 123 municipalities Brazil’s 26 states and Federal District. ENANI-2019 includes breastfeeding dietary intake; anthropometric nutritional status all their biological...
Background: The role of circulating metabolites on child development is understudied. We investigated associations between children's serum metabolome and early childhood (ECD). Methods: Untargeted metabolomics was performed samples 5,004 children aged 6-59 months, a subset participants from the Brazilian National Survey Child Nutrition (ENANI-2019). ECD assessed using Well-being Young Children's milestones questionnaire. graded response model used to estimate developmental age....
Introduction The full achievement of early childhood development (ECD) is a human right and adhering to the nurturing care framework may facilitate it. Objective To evaluate association between distal proximal variables developmental quotient (DQ). Methods Data from 14 159 children <5 years were evaluated in Brazilian National Survey on Child Nutrition. Well-being Young Children—Brazilian version milestones questionnaire was used ECD. age estimated using graded response models. DQ...
Abstract Understanding the determinants of malnutrition is pivotal for public health interventions. This study aimed to identify socio-economic, demographic, dietary, and maternal wasting overweight among Brazilian children between 6–59 months. Data from National Survey on Child Nutrition were analyzed (n=11,789). Children’s weight-for height Z scores calculated according WHO growth standard classified as (Z < -2), normal weight (-2 ≤ ≤1), risk (1 2), > 2). Socio-economic, covariables...
Factors associated with anemia and vitamin A deficiency were investigated in 7,716 children 6-59 months of age studied the Brazilian National Survey on Child Nutrition (ENANI-2019). We adopted a hierarchical approach based United Nations Children's Fund (UNICEF) theoretical model three levels, stratifying by (6-23; 24-59 months). Prevalence ratio (PR) 95% confidence interval (95%CI) estimated. Enabling determinants: higher prevalence was observed 6-23 whose mothers had ≤ 7 years schooling...
The study aimed to estimate the prevalence of minimum dietary diversity (MDD) and consumption ultra-processed foods in children 6-23 months age according sociodemographic variables. Three indicators complementary feeding 4,354 from Brazilian National Survey on Child Nutrition (ENANI-2019) were built based a questionnaire about food day before interview: MDD, foods, MDD without foods. 95%CI calculated, stratified by macroregion; race/skin color, education work status mother or caregiver;...
This study aimed to characterize micronutrient supplements use among Brazilian children 6-59 months of age included in the National Survey on Child Nutrition (ENANI-2019; n = 12,598). Micronutrient at time interview and 6 prior it was evaluated using a structured questionnaire. The following indicators were included: supplement use; containing single micronutrient; Iron Supplementation Program (PNSF); multivitamin with or without minerals; minerals. estimates their respective 95% confidence...
Malnutrition affects billions of individuals worldwide and represents a global health challenge. This study aimed to determine the prevalence malnutrition (undernutrition or overweight) among mother-child dyads in children under 5 years old Brazil 2019 estimate changes this from 2006 2019. Individual-level data Brazilian National Survey on Child Nutrition (ENANI-2019) Demography Health Women Children carried out (PNDS 2006) were analyzed. outcomes included overweight mother child,...
The objective of this study was to describe the frequency cross-breastfeeding, human milk donation banks and reception from banks, investigate intersection between cross-breastfeeding breast practices. This used data national household-based survey Brazilian National Survey on Child Nutrition (ENANI-2019), which collected information 14,558 children < 5 years old February 2019 March 2020. present included 5,831 biological mothers who reported having breastfed their child 2 at least once...

This article aims to present methodological aspects on the collection, analyses, coverage, challenges, and lessons learned from laboratory assessment of micronutrients Brazilian National Survey Child Nutrition (ENANI-2019). is a household survey probability sample children under five years age 123 municipalities in all 26 states Federal District. Blood samples were drawn by venipuncture at homes 6 59 months age. procedure was performed experienced phlebotomists laboratories located selected...
The National Wealth Score (IEN) is a synthetic household index that assesses socioeconomic conditions. This study aims to present the methods used update IEN using data from Brazilian Survey on Child Nutrition (ENANI-2019). following items were included: education level of mother or caregiver child; number bedrooms and bathrooms, TV sets, cars in household; presence radio, refrigerator freezer, washing machine, microwave oven, telephone line, computers, air conditioner, media player devices,...
We investigated whether calcium plus vitamin D supplementation interacts with polymorphisms in the VDR gene promoter region to affect changes on maternal bone mass from 5 20 wk postpartum Brazilian adolescent mothers.Pregnant adolescents (14-19 y) randomly received cholecalciferol (600 mg/d + 200 IU/d, n = 30) or placebo (n 26) 26 of pregnancy until parturition. Bone mineral content (BMC), area (BA), and density (BMD) at total body, lumbar spine, hip, femoral neck were evaluated postpartum....
Abstract To analyse the association of socio-demographic and health factors with vitamin D insufficiency 25-hydroxyvitamin (25(OH)D) concentration in Brazilian children aged 6–59 months. Data from 8145 National Survey on Child Nutrition (ENANI-2019) were analysed. The serum 25(OHD)D was measured using a chemiluminescent immunoassay. prevalence (25(OH)D < 50 nmol/l) 95 % CI calculated. Logistic linear regression models used to identify variables associated 25(OH)D concentrations,...
Abstract Objective: To describe the prevalence of food poverty according to dimensions socio-economic inequality and groups consumed by Brazilian children. Design: Dietary data from a structured qualitative questionnaire collected National Survey on Child Nutrition (ENANI-2019) were used. The new UNICEF indicator classified children who 3–4 <3 out eight as living in moderate severe poverty, respectively. consumption each group ultra-processed foods (UPF) was estimated level age categories...
Mass spectrometry (MS)-based metabolomics often rely on separation techniques when analyzing complex biological specimens to improve method resolution, metabolome coverage, quantitative performance, and/or unknown identification. However, low sample throughput and complicated data preprocessing procedures remain major barriers affordable metabolomic studies that are scalable large populations. Herein, we introduce PeakMeister as a new software tool in the R statistical environment enable...
