The SARS-CoV-2 coronavirus pandemic posed an unprecedented challenge to global health. In the context of an overwhelmed healthcare system and the rising demand for alternative strategies to manage stress and anxiety, this study aims to investigate and analyze the use of Integrative and Complementary Practices (ICP) in Brazil during the COVID-19 pandemic, emphasizing their importance in promoting health and well-being. We conducted a cross-sectional study among n = 12,136 Brazilian adults predominantly female, white, under 40 years of age and with a predominantly higher education level between August 24 and December 16, 2020, to assess the use of ICP. An online questionnaire was applied, with questions validated in previous health surveys. The sampling method employed was 'virtual snowball,' post-stratification procedures were used to consider the Brazilian regions, gender, age group, and educational level. The reported prevalence of ICP use was 61.8%, with meditation (28.2%), Reiki (21.7%), herbal medicine (28.2%), and aromatherapy (16.5%) being the most utilized practices. ICPs were more frequently adopted by females, older age groups, individuals with health insurance, and those who practiced social distancing. Health promotion and well-being were the primary reasons for engaging in ICP. The high adherence to ICP during the COVID-19 pandemic in Brazil reflects the population's search for therapeutic alternatives focused on the well-being and mental health. The utilization of ICP indicates the need to integrate these practices into healthcare systems, considering their potential to complement conventional treatment, especially in times of crisis. Public health policies should recognize and facilitate access to such practices to reduce inequities and promote integrative health. This study contributes to the understanding of the role of ICP in a public health crisis, encouraging further investigation into the potential inclusion of these practices in the healthcare system.

OBJECTIVE: To analyze the association between maternity leave and exclusive breastfeeding and to estimate the prevalence of exclusive breastfeeding in children under six months of life. METHODS: Cross-sectional study, with mothers of children under six months of life, attended in primary health care units with Breast Milk Collection Services in the municipality of Rio de Janeiro, Brazil, in 2013 (n = 429). We analyzed characteristics concerning: maternal sociodemographic aspects, household, prenatal care, childbirth, maternal lifestyle, the child, health care, and infant feeding. Adjusted prevalence ratios (APR) were obtained by Poisson regression with robust variance according to hierarchical approach, and we kept in the final model variables that were associated (p = 0.05) with exclusive breastfeeding (outcome). RESULTS: Among the interviewed mothers, 23.1% were on maternity leave and 17.2% were working. The prevalence of exclusive breastfeeding was 50.1%. The maternal work with maternity leave was associated with higher prevalence of the outcome (APR = 1.91; 95%CI 1.32-2.78), compared with mothers who worked without maternity leave. CONCLUSIONS: Maternity leave has contributed to the practice of exclusive breastfeeding for children under six months of life, which indicates the importance of this benefit in protecting exclusive breastfeeding for women inserted in the formal labor market.

To estimate the non-Hodgkin lymphoma (NHL) mortality risk among agricultural workers in Brazil's southern states, we used death certificates to identify cases of NHL between the ages of 20 and 69 years from residents of nonurban municipalities between 1996 and 2005 (n= 1,317). Controls were randomly selected from those whose underlying cause of death did not include neoplasm or hematological diseases and paired with cases by sex, age, year of death, and state of residence (n= 2,634). Odds of being an agricultural worker among cases and controls were estimated by conditional logistic regression, stratified and adjusted by sex, state, education, and race. An increased risk of death by NHL was observed among agricultural workers 20–39 years old (ORadj= 2.06; 95% CI 95%, 1.20–3.14). Our results suggest that the young agricultural workers from southern Brazil were more likely to die of NHL compared to nonagricultural workers. [ABSTRACT FROM AUTHOR]

Background: Breastfeeding in the first hour after birth is important for the success of breastfeeding and in reducing neonatal mortality. Government policies are being developed in this direction, highlighting the accreditation of hospitals in the Baby-Friendly Hospital (BFH) initiative. The aim of this study was to analyze the association between delivery in a BFH (main exposure), compared to non BFH, and timely initiation of breastfeeding (outcome). Methods: Data came from the "Birth in Brazil" survey, a nationwide hospital-based study of postpartum women and their newborns, coordinated by the Oswaldo Cruz Foundation. A sample of 22,035 mothers/babies was analyzed through a hierarchical theoretical model on three levels, and all analyzes considered the complex sample design. Odds ratios were obtained by logistic regression, with a 99 % CI. Results: Among all births, 40 % occurred in hospitals accredited or in accreditation process for the BFHI and 52 % of women underwent caesarean section. In the final model, at the distal level, mothers less than 35 years old, and those who lived in the North Region, had a higher chance of timely initiation of breastfeeding. At the intermediate level, prenatal care in the public sector and advice on breastfeeding during pregnancy were directly associated with the outcome. At the proximal level, being born in a Baby-Friendly Hospital and vaginal delivery increased the chance of timely initiation of breastfeeding, while prematurity and low birth weight reduced the chance of the outcome.

Objective: To evaluate the relationship between breastfeeding and hospitalization for pneumonia among children under 1 year old. Methods: Ecological study using secondary data of hospitalizations for pneumonia (outcome) and breastfeeding prevalence data (exposure) among children under 1 year old living in the Brazilian state capital cities and the Federal District in 2008. A negative binomial model of hospitalization was used to estimate the rate ratio (95% confidence interval), adjusted according to the Gini Index, and the prevalence rates of smokers in the general population and low birth weight individuals in the population investigated. Results: Breastfeeding prevalence among children between 9 and 12 months old and exclusive breastfeeding prevalence among children under 6 months old were associated with a lower rate ratio of hospitalization for pneumonia (RR = 0.62; 95%CI 0.51-0.74 and RR = 0.52; 95%CI 0.39-0.69, respectively). Conclusion: Increased prevalence rates of breastfeeding during the first year of life and exclusive breastfeeding during the first 6 months of life can reduce the number of hospitalizations for pneumonia.

OBJECTIVE: To identify factors associated with breastfeeding in the first hour of life (Step 4 of the Baby-Friendly Hospital Initiative). METHODS: A cross-sectional study was conducted with a representative sample of mothers who gave birth in maternity wards in the city of Rio de Janeiro, Southeastern Brazil, between 1999 and 2001. Newborns or mothers with restriction to breastfeeding were excluded, resulting in a sample of 8,397 pairs. A random effect -- at maternity hospital level -- Poisson model was employed in a hierarchical approach with three levels: distal, intermediate and proximal for characteristics of the mother, of the newborn, and of prenatal and hospital assistance. RESULTS: Only 16% of the mothers breastfed in the first hour of life. Breastfeeding in this period was less prevalent among neonates with immediate intercurrences after birth (PR = 0.47; CI99% 0.15;0.80); among mothers who did not have contact with their newborns in the delivery room (PR = 0.62; CI99% 0.29;0.95); among mothers submitted to cesarean section delivery (PR = 0.48; CI99% 0.24;0.72); and among mothers who gave birth at private maternity hospitals (PR = 0.06; CI99% 0.01;0.19) or at maternity hospitals contracted out to National Health System (SUS) (PR = 0.16; CI99% 0.01;0.30). The context effect of maternity wards was statistically significant. CONCLUSIONS: At an individual level, breastfeeding within one hour after birth was constrained by inappropriate practices in private or SUS-contracted maternity hospitals. The group effect of maternity hospitals and the absence of individual maternal-related factors that explain the outcome suggest that mothers have little or no autonomy to breastfeed their babies within the first hour of life, and depend on the institutional practices that prevail at the maternity hospitals.

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.

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.

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.

Malnutrition affects billions of individuals worldwide and represents a global health challenge. This study aimed to determine the prevalence of malnutrition (undernutrition or overweight) among mother-child dyads in children under 5 years old in Brazil in 2019 and to estimate changes in this prevalence from 2006 to 2019. Individual-level data from the Brazilian National Survey on Child Nutrition (ENANI-2019) and the Brazilian National Survey of Demography and Health of Women and Children carried out in 2006 (PNDS 2006) were analyzed. Malnutrition outcomes in mother-child dyads included overweight mother and child, undernourished mother and child, and the double burden of malnutrition, i.e., overweight mother and child having any form of undernourishment (stunting, wasting, or underweight). Prevalence and 95% confidence intervals (95%CI) were estimated. Most women (58.2%) and 9.7% of the children were overweight, 6.9% were stunted, and 3.1% of mothers and 2.9% of the children were underweight. The prevalence of overweight in the mother-child dyad was 7.8% and was statistically higher in Southern Brazil (9.7%; 95%CI: 7.5; 11.9) than in the Central-West (5.4%; 95%CI: 4.3; 6.6). The prevalence of overweight mother and stunted child was 3.5%, with statistically significant difference between the extremes of the mother's education [0-7 vs. ≥ 12 years, 4.8% (95%CI: 3.2; 6.5) and 2.1%, (95%CI: 1.2; 3.0), respectively]. Overweight in the dyad increased from 5.2% to 7.8%, and the double burden of malnutrition increased from 2.7% to 5.2% since 2006. Malnutrition in Brazilian mother-child dyads seems to be a growing problem, and dyads with lower formal education, higher maternal age, and from the South Region of Brazil were more vulnerable.

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., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

The National Wealth Score (IEN) is a synthetic household index that assesses socioeconomic conditions. This study aims to present the methods used to update the IEN using data from the Brazilian National Survey on Child Nutrition (ENANI-2019). The following items were included: the education level of the mother or caregiver of the child; the number of bedrooms and bathrooms, TV sets, and cars in the household; and the presence of a radio, refrigerator or freezer, washing machine, microwave oven, telephone line, computers, air conditioner, media player devices, cable or satellite TV, cell phone ownership and type of service, cell phone internet, and internet at the household. Principal component analysis (PCA) was used to estimate the IEN with and without incorporating the complex sampling design (CSD). Thus, the IEN validation considered proxy indicators of socioeconomic status and living conditions. The first component of the PCA explained 31% and 71% of the variation with and without incorporating the CSD, respectively. The coefficients of variation of the IEN were 53.4% and 2.6% with and without incorporating the CSD, respectively. The mean IEN score was lower in households without access to a sewage system, those that received benefits from Brazilian Income Transfer Program, those with some degree of food insecurity, and those with stunted children. Adding ENANI-2019 items to the calculation of IEN to capture technological advances resulted in a better fit of the model. Incorporating the CSD increased PCA performance and the IEN precision. The new IEN has an adequate performance in determining the socioeconomic status of households with children aged under five years.

Objective: To estimate the prevalence of exclusive breastfeeding during maternity hospital stay (outcome) and to analyze the association between delivery in a Baby-Friendly Hospital (BFH) and the outcome. The hypothesis is that accreditation to this program improves exclusive breastfeeding during maternity hospital stay. Exclusive breastfeeding is essential in reducing neonatal morbidity and mortality., Methods: This study is based on secondary data collected by the "Birth in Brazil: National Survey into Labour and Birth", a population-based study, conducted with 21,086 postpartum women, from February 1, 2011, to October 31, 2012, in 266 hospitals from all five Brazilian regions. Face-to-face interviews were conducted mostly within the first 24 hours after birth, regarding individual and gestational characteristics, prenatal care, delivery, newborn's characteristics, and breastfeeding at birth. A theoretical model was created, allocating the exposure variables in three levels based on their proximity to the outcome. This hierarchical conceptual model was applied to perform a multiple logistic regression (with 95%CI and p < 0.05)., Results: In this study, 76.0% of the babies were exclusively breastfed from birth until the interview. Babies born in public (AOR = 1.73; 95%CI: 1.10-2.87), mixed (AOR = 2.48; 95%CI: 1.35-4.53) and private (AOR = 5.54; 95%CI: 2.38-12.45) BFHs were more likely to be exclusively breastfed during maternity hospital stay than those born in non-BFHs, as well as those born by vaginal birth (AOR = 2.16; 95%CI: 1.79-2.61), with adolescent mothers (AOR = 1.83; 95%CI: 1.47-2.26) or adults up to 34 years old (AOR =1 .31; 95%CI: 1.13-1.52), primiparous women (AOR = 1.51; 95%CI: 1.34-1.70), and mothers living in the Northern region of Brazil (AOR = 1.99; 95%CI: 1.14-3.49)., Conclusions: The Baby-Friendly Hospital Initiative promotes exclusive breastfeeding during hospital stay regarding individual and hospital differences.

Objective: To analyze the receipt of sponsorships from breast-milk substitute companies by health professionals in scientific events., Methods: Multicenter study (Multi-NBCAL) performed from November 2018 to November 2019 in six cities in different Brazilian regions. In 26 public and private hospitals, pediatricians, nutritionists, speech therapists, and a hospital manager were interviewed using a structured questionnaire. Descriptive analyses were carried out regarding the health professionals' knowledge about the Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância, Bicos, Chupetas e Mamadeiras (NBCAL - Brazilian Code of Marketing of Infant and Toddlers Food and Childcare-related Products), companies sponsoring scientific events, and material or financial sponsorships received, according to profession., Results: We interviewed 217 health professionals, mainly pediatricians (48.8%). Slightly more than half of the professionals (54.4%) knew NBCAL, most from Baby-friendly Hospitals. Most health professionals (85.7%) attended scientific events in the last two years, more than half of them (54.3%) sponsored by breast-milk substitute companies, especially Nestlé (85.1%) and Danone (65.3%). These professionals received sponsorships in the events, such as office supplies (49.5%), meals or invitations to parties (29.9%), promotional gifts (21.6%), payment of the conference registration fee (6.2%) or ticket to the conference (2.1%)., Conclusion: The infant food industries violate NBCAL by harassing health professionals in scientific conferences, offering diverse material and financial sponsorships.

Objective: To analyze if milk and complementary foods are being sold under the Brazilian Code of Marketing of Infant and Toddler's Food, Teats, Pacifiers and Baby Bottles (NBCAL), Law 11265/2006 of breastfeeding protection., Methods: Epidemiological survey that analyzed the marketing practices of pharmacies, supermarkets, and department stores in the Southern region of the city of Rio de Janeiro, Brazil, by direct observation., Results: Among the 349 stores in Rio de Janeiro's South Region, 339 traded milk and complementary foods and, among them, 60.8% were not complying with NBCAL. Infractions to NBCAL were more common for the selling of milk (58.6%) than complementary foods (22.8%). The most recurrent promotion strategy infringing NBCAL was discount pricing without the Ministry of Health disclaimer., Conclusions: Most retail stores infringe NBCAL in the commercialization of milk and complementary foods in the city of Rio de Janeiro, Brazil, a violation of the right to information that may impact mothers' choice regarding their child's feeding.

The Brazilian Code of Marketing of Infant and Toddlers Food, Nipples, Pacifiers and Baby Bottles (NBCAL), in force in Brazil since 1988, is still systematically violated, exposing mothers and family members to illegal marketing of products that compete with breastfeeding. This study aimed to describe a multicenter study methodology and propose standardized indicators for NBCAL monitoring. This is a Multicenter Study for NBCAL Compliance Assessment (Multi-NBCAL) conducted in seven Brazilian cities: Rio de Janeiro, São Paulo, Ouro Preto (Minas Gerais State), Florianópolis (Santa Catarina State), Brasília (Federal District), João Pessoa (Paraíba State), and Belém (Pará State). Assessment tools were adapted from NetCode/WHO and IBFAN Brazil (International Baby Food Action Network) to conduct two evaluations: (1) evaluation of NBCAL compliance in stores, and NBCAL knowledge and practices of store managers; (2) evaluation of the interaction between the baby food industry and health professionals and post-partum mothers in maternity hospitals. Five indicators were developed to assess NBCAL compliance in stores; seven indicators to assess the knowledge and practices of store managers; five indicators to assess the provision of incentives to maternity hospitals, health professionals, and mothers by sectors; and five indicators to assess NBCAL knowledge and practices of health professionals. The NBCAL assessment methodology with the proposal of standardized indicators allows comparability of studies about this theme. Using these indicators in periodic national or regional investigation can help monitor the level of NBCAL implementation in Brazil.

This study evaluated the role of social inequalities in complementary feeding patterns between and within countries in Latin America and the Caribbean. This ecological study employed aggregate data from population-based surveys. The units of analysis were all 16 countries in Latin America and the Caribbean for which information was available in the Demographic and Health Surveys (DHS) and Multiple Indicator Cluster Surveys (MICS) databases. The outcomes selected were the prevalences indicated by the "introduction of solid, semi-solid or soft foods" (ISSSF), "minimum dietary diversity" (MDD), "minimum meal frequency" (MMF) and "minimum acceptable diet" (MAD) standardised complementary feeding indicators recommended by the WHO and available in UNICEF databases. The differences in prevalences between the wealthiest and poorest income quintiles were calculated in absolute and relative terms. Comparing the four indicators of complementary feeding, the ISSSF showed best performance, returning prevalence above 80% in 10 of the 11 countries evaluated. The indicator showing worst performance was the MAD, with prevalence above 60% in only one of the eight countries evaluated. In almost all countries, by all indicators, prevalences of complementary feeding were lower in the poorest population groups than in the wealthiest.

This manuscript aims to describe the methodological, operational, and quality control aspects of the assessment of dietary intake in children under five years of age participating in the Brazilian National Survey on Child Nutrition (ENANI-2019), a household survey in a probability sample of Brazilian households. Two instruments were developed to assess child feeding practices - a structured, current status-type questionnaire and a 24-hour dietary recall (24HR), both installed in a mobile data collection device used by previously trained interviewers. A Photographic Manual for Quantification of Children's Dietary Intake was specifically developed for and used in the survey as a support aid to identify and quantify foods reported in the 24HR. During the fieldwork, continuous quality control of the records was performed. Data errors or incomplete data in the system were corrected, and the fieldwork team was systematically contacted and informed on their performance, with reiterated orientation on data collection. All children in the sample were evaluated with the two instruments, but data were obtained from the structured questionnaire on all children in the sample (n = 14,558) and 24HR on 14,541 children. ENANI-2019 developed innovative methods and materials based on the Brazilian and international literature to address knowledge gaps on under-five children's dietary intake. Unprecedented results will be produced, which will allow updating food and nutrition guidelines for children under five years of age in Brazil.

The article presents methodological aspects of anthropometric assessment of nutritional status in children under five years of age and their biological mothers. It discusses the strategies used for training and data collection in the Brazilian National Survey on Child Nutrition (ENANI-2019). ENANI-2019 is a population-based household survey conducted in 123 municipalities in Brazil's 26 states and the Federal District. The anthropometric measurements were body mass and length/stature. The equipment was purchased according to its measurement capacity and precision, portability, and cost-benefit ratio after an extensive market search. The study used internationally established procedures described in manuals, videos, and support material developed for the study by a group of experts. The interviewers were trained to perform the anthropometric measurements and were assessed according to technical measurement error, which was considered adequate (0.30cm) for the children's length/stature measurements. Measurement errors were identified, and the interviewers were retrained when necessary. Of the 14,558 children in the sample, body mass and length/stature measurements were taken in duplicate in 13,835 and 13,693 children, respectively. The standardized methodological aspects will be helpful in future population studies and were essential for obtaining greater reliability in the data for generating current evidence on the anthropometric assessment of the nutritional status of Brazilian children under five years of age, allowing new perspectives for public policy development.

The article describes methodological aspects in defining the study population, sampling plan, and sample weigthing and calibration of effective sample of the Brazilian National Survey on Child Nutrition (ENANI-2019). This population-based household survey assessed breastfeeding and dietary intake, anthropometric assessment of nutritional status, and micronutrient deficiencies by blood biomarkers in children under five years of age. The data were obtained with a probability sample, with stratification by the five geographic regions in the country and clustering by census enumeration areas (CEAs). The sample was calculated at 15,000 households distributed in 1,500 CEAs, with 300 allocated in each of Brazil's five major geographic regions and 10 eligible households per CEA, sampled using inverse sampling. The required population parameters were thus estimated to reach the study's objectives. The basic sampling design weights were calculated as the inverse probabilities of the households' inclusion in the study. Imputation was used to compensate for non-response to items in the target variables, except for data on the blood biomarkers. Finally, calibration used population totals of children in 60 post-strata, defined by cross-classification of the following variables: major geographic region, sex, and age. The final sample included 14,558 children residing in 12,524 households, distributed in 1,382 CEAs in the 26 states of Brazil and the Federal District. The data from the ENANI-2019 survey will support strategies for the promotion and implementation of public policies for children under five years of age.

This article aims to present methodological aspects on the collection, analyses, coverage, challenges, and the lessons learned from laboratory assessment of micronutrients on the Brazilian National Survey on Child Nutrition (ENANI-2019). This is a household survey on a probability sample of children under five years of age from 123 Brazilian municipalities in all 26 states and the Federal District. Blood samples were drawn by venipuncture at the homes of children 6 to 59 months of age. This procedure was performed by experienced phlebotomists from the laboratories located in the selected municipalities and scheduled in advance. Blood and serum levels were measured for biomarkers of nutritional status, using the services of a clinical test laboratory with nationwide coverage, for the following micronutrients: iron (hemoglobin and ferritin), zinc, selenium, folic acid, and vitamins A, B1, B6, B12, D, and E. C-reactive protein was analyzed as a marker of inflammation. A barcode identifier was used to track the blood samples and to link the biochemical test results to the other data collected in the survey. A total of 14,558 children were studied. Of the 12,598 eligible children, 8,829 (70.1%) had blood samples drawn. Of the total number of children who had samples drawn, 91.8% (n = 8,025) have results for at least nine of the 12 analyses performed. Coverage of the analysis varied from 95% (for vitamins A and E) to 84.2% (for folic acid). Aliquots of whole blood and serum were stored in a biorepository for future analyses. The results of this pioneering study in the country will back the formulation and, when necessary, the reorientation of public policies in food and nutrition.

This article aims to present general methodological aspects of the Brazilian National Survey on Child Nutrition (ENANI-2019), from the conception of the study design to details of the data collection. This is a household-based population survey with a sample calculated at 15,000 households to identify children under five years of age, conducted in 123 municipalities in Brazil's 26 states and the Federal District. ENANI-2019 includes data on breastfeeding and dietary intake; anthropometric nutritional status of all children and their biological mothers; and nutritional status concerning the following micronutrients: iron (hemoglobin and ferritin), zinc, selenium, and vitamins A, B1, B6, B12, D, E, and folic acid of children from 6 to 59 months of age. A total of 193,212 households were visited, of which 19,951 were eligible, and 12,524 were included in the study. A total of 14,558 children were studied, of whom 13,990 (96.1%) and 13,921 (95.6%) had their body mass and length/stature measured, respectively, and 14,541 (99.9%) underwent 24-hour dietary recalls (24HR). Of the 12,598 children eligible for blood sample collection, 8,739 (69.3%) had at least one laboratory parameter measured. Data were collected from February 2019 to March 2020, when the survey was interrupted due to the COVID-19 pandemic. The evidence produced by the ENANI-2019 survey can back the formulation, follow-up, and/or reorientation of food and nutrition policies such as the promotion of breastfeeding and healthy eating and the prevention and control of different forms of malnutrition.

Objective: To assess if the commercialization of infant formulas, baby bottles, bottle nipples, pacifiers and nipple protectors is performed in compliance with the Norma Brasileira de Comercialização de Alimentos para Lactentes e Crianças de Primeira Infância e de Produtos de Puericultura Correlatos (NBCAL - Brazilian Code of Marketing of Infant and Toddlers Food and Childcare-related products). The commercial promotion of these products is prohibited by the Law 11,265., Method: Cross-sectional study conducted in 2017 through a census of all pharmacies, supermarkets and department stores that sold products covered by NBCAL in the South Zone of Rio de Janeiro. Health professionals trained at NBCAL used structured electronic form for direct observation of establishments and for interviews with their managers. We created indicators to evaluate commercial practices and performed descriptive analyses., Results: A total of 352 commercial establishments were evaluated: 240 pharmacies, 88 supermarkets and 24 department stores, of which 88% sold products whose promotion is prohibited by NBCAL. Illegal commercial promotions were found in 20.3% of the establishments that sold the products we investigated: 52 pharmacies (21.9%), four supermarkets (7.5%) and seven department stores (33.3%). The most frequent commercial promotion strategies were discounts (13.2%) and special exposures (9.3%). The products with the highest prevalence of infractions of NBCAL were infant formulas (16.0%). We interviewed 309 managers of commercial establishments; 50.8% reported unfamiliarity with the law. More than three-quarters of the managers reported having been visited at the establishments by commercial representatives of companies that produce infant formulas., Conclusion: More than a fifth of commercial establishments promoted infant formulas, baby bottles and nipples, although this practice has been banned in Brazil for thirty years. We think it is necessary to train those managers. Government agencies must monitor commercial establishments in order to inhibit strategies of persuasion and induction to sales of these products, ensuring mothers' autonomy in the decision on the feeding of their children.

Objective: to describe the measurement process of the body mass in children under seven years old, assisted by community health agents in primary health care units of the Family Health Strategy, in Macaé-RJ, Brazil., Methods: a descriptive study with community health agents who measured the body mass of children, from August 2010 to August 2011., Results: ¾ (n=65) of the community health agents from Macaé Primary Health Care were observed in 196 measurements; in 66.8% of measurements, the professionals used domestic scales (p<0.001); 65.3% of the scales were put on uneven floor; the procedure 'undress the child' was followed in 18.4% of cases; of those, 72.2% were performed properly (p<0.001)., Conclusion: failures in the technical procedures of measurement were detected, pointing to the need to expand the reflection and discussion on the impact of the measurements, which help determine the nutritional diagnose of children.

Objective: Update breastfeeding indicators trend in Brazil for the last three decades, incorporating more up-to-date information from the National Health Survey., Methods: We used secondary data from national surveys with information on breastfeeding (1986, 1996, 2006, and 2013) to construct the time series of prevalence for the following indicators: exclusive breastfeeding in children under six months of age (EBF6m), breastfeeding in toddlers under 2 years of age (BF), continued breastfeeding at one year of age (BF1year), and continued breastfeeding at two years of age (BF2years)., Results: The prevalence of EBF6m, BF, and BF1year increased until 2006 (rising from 4.7%, 37.4%, and 25.5% in 1986 to 37.1%, 56.3%, and 47.2% in 2006, respectively). For these three indicators, there was relative stabilization between 2006 and 2013 (36.6%, 52.1%, and 45.4%, respectively). The BF2years indicator had a distinct behavior - relatively stable prevalence, around 25% between 1986 and 2006, and a subsequent increase, reaching 31.8% in 2013., Conclusions: The time series of breastfeeding indicators in Brazil shows an upward trend until 2006, stabilizing from that date onwards on three of the four indicators evaluated. This result, which can be considered as a warning sign, requires evaluation and revision of policies and programs to promote, protect and support breastfeeding, strengthening existing ones and proposing new strategies so that the prevalence of breastfeeding indicators returns to an upwards trend.
