Abstract The present study aimed to investigate the socioeconomic and obstetric characteristics of adolescent mothers and the complications they cause to maternal and neonatal health. This baseline data analysis of the MINA-Brazil birth cohort was conducted in the municipality of Cruzeiro do Sul, state of Acre, Brazil. The chi-square test was used to compare characteristics of adolescent and adult postpartum women, and multiple Poisson regression models with robust variance were used to assess associated factors. Among the postpartum women, 26.2% (95%CI: 24.0-28.4) were adolescents. Factors associated with childbirth in adolescence included: nine years or less of schooling (adjPR:1.36; 95%CI: 1.14-1.61), belongs to the lowest quartiles of the wealth index (1st quartile: adjPR:1.40; 95%CI: 1.08-1.80) (2nd quartile: adjPR:1.37; 95%CI: 1.08-1.74), primigravidae (adjPR:3.69; 95%CI: 2.98-4.57), low pre-pregnancy BMI (adjPR:1.28; CI95%: 1.04-1.57), urinary tract infection during pregnancy (adjPR:1.25; CI95%: 1.07-1.46) and less than six prenatal consultations (adjPR:1.42; 95%CI: 1.21-1.66). Poverty, little schooling, primigravidae, low pre-pregnancy BMI, urinary tract infection during pregnancy and few prenatal consultations were associated with childbirth during adolescence in a municipality in the Northern region of Brazil.

ABSTRACT OBJECTIVE To review observational studies on the association between breastfeeding (BF) practices and head circumference (HC) of children < 2 years old. METHODS A systematic review was conducted using the following electronic databases of health sciences: PubMed, Latin American and Caribbean Literature in Health Sciences (Lilacs), Web of Science and Scopus. We selected observational studies published in any language from January 01, 2010 to November 19, 2021, from different populations that investigated the association between BF practice and HC among healthy children < 2 years old. Titles and abstracts were screened independently by two evaluators. RESULTS From the 4,229 articles identified, 24 were included in this review: 6 cross-sectional, 17 longitudinal, and 1 case-control. The studies varied in their definition of the variables for BF and in reporting its practice, frequency, duration, and feeding method. Regarding HC, the authors analyzed the mean differences, abnormal values (z-score above + 2SD or below -2SD according to the World Health Organization (WHO) growth standards, 2007), and longitudinal growth parameters. The findings of this review suggest that BF may have a positive relationship with HC at the beginning of life. CONCLUSIONS Our findings suggest that BF, especially exclusive BF, may play a protective role against abnormal HC values in young children. However, more robust evidence with standardized BF indicators and WHO growth standards (2007) are required.

ABSTRACT OBJECTIVE: To investigate birth-to-childhood tracking of linear growth and weight gain across the distribution of length/height and weight for age z-scores and according to household wealth. METHODS: Data from 614 children from the MINA-Brazil Study with repeated anthropometric measurements at birth and up to age five years were used. Z-scores were calculated for length/height (HAZ) and weight (WAZ) according to international standards. Birth-to-childhood tracking was separately estimated using quantile regression models for HAZ and WAZ, extracting coefficients and 95% confidence intervals (95%CI) at the 25th, 50th, and 75th quantiles. In a subgroup analysis, we estimated tracking between birth and age two years, and between ages two and five years. To investigate disparities in tracking, interaction terms between household wealth indexes (at birth and age five years) and newborn size z-scores were included in the models. RESULTS: Tracking coefficients were significant and had similar magnitude across the distribution of anthropometric indices at age five years (HAZ, 50th quantile: 0.23, 95%CI: 0.11 to 0.35; WAZ, 50th quantile: 0.31, 95%CI: 0.19 to 0.43). Greater tracking was observed between ages two and five years, with coefficients above 0.82. Significantly higher tracking of linear growth was observed among children from wealthier households, both at birth, at the lower bounds of HAZ distribution (25th quantile: 0.30, 95%CI: 0.13 to 0.56), and during childhood, in the entire HAZ distribution at five years. For weight gain, stronger tracking was observed at the upper bounds of WAZ distribution at age five years among children from wealthier households at birth (75th quantile: 0.59, 95%CI: 0.35 to 0.83) and during childhood (75th quantile: 0.54, 95%CI: 0.15 to 0.93). CONCLUSION: There was significant tracking of HAZ and WAZ since birth, with indication of substantial stability of nutritional status between ages two and five years. Differential tracking according to household wealth should be considered for planning early interventions for preventing malnutrition.

RESUMO OBJETIVO: Investigar a autocorrelação do crescimento linear e ganho de peso do nascimento até a infância considerando a distribuição de escores z de comprimento/estatura e peso por idade e de acordo com a riqueza domiciliar. MÉTODOS: Foram utilizados dados de 614 crianças do Estudo MINA-Brasil com medições antropométricas realizadas do nascimento até os cinco anos de idade. Escores z foram calculados para comprimento/estatura (HAZ) e peso (WAZ) seguindo padrões internacionais. A autocorrelação ou estabilidade da adequação do estado nutricional do nascimento à infância foi estimada por meio de modelos de regressão quantílica para HAZ e WAZ, separadamente, extraindo-se coeficientes e intervalos de confiança de 95% (IC95%) nos quantis 25, 50 e 75. Em uma análise de subgrupo, estimou-se a autocorrelação entre o nascimento até os dois anos de idade, e entre dois e cinco anos de idade. Para investigar disparidades na autocorrelação, termos de interação entre índices de riqueza familiar (ao nascer e aos cinco anos de idade) e escores z de tamanho do recém-nascido foram incluídos nos modelos. RESULTADOS: Os coeficientes de autocorrelação foram significantes e tiveram magnitude semelhante ao longo da distribuição dos índices antropométricos aos cinco anos de idade (HAZ, quantil 50: 0,23, IC95%: 0,11 a 0,35; WAZ, quantil 50: 0,31, IC95%: 0,19 a 0,43). Maior estabilidade do estado nutricional foi observada entre dois e cinco anos, com coeficientes acima de 0,82. Autocorrelação significantemente maior do crescimento linear foi observada entre as crianças de domicílios mais ricos, tanto ao nascer, nos limites inferiores da distribuição HAZ (quantil 25: 0,30, IC95%: 0,13 a 0,56) e durante a infância, em toda a distribuição HAZ aos cinco anos. Para o ganho de peso, observou-se uma autocorrelação mais forte nos limites superiores da distribuição do WAZ aos cinco anos de idade entre as crianças de domicílios mais ricos ao nascer (quantil 75: 0,59, IC95%: 0,35 a 0,83) e durante a infância (quantil 75: 0,54, IC95%: 0,15 a 0,93). CONCLUSÃO: Houve autocorrelação significante de HAZ e WAZ desde o nascimento, com indicação de substancial estabilidade do estado nutricional entre os dois e cinco anos de idade. A autocorrelação diferencial de acordo com a riqueza domiciliar deve ser considerada para o planejamento de intervenções precoces para prevenir a má nutrição.

ABSTRACT Vaccination coverage has been dropping in Brazil and other countries. In addition, immune responses after vaccination may not be homogeneous, varying according to sociodemographic and clinical factors. Understanding the determinants of incomplete vaccination and negative antibody test results may contribute to the development of strategies to improve vaccination effectiveness. In this study, we aimed to investigate the frequency of vaccine adherence, factors associated with incomplete vaccination for measles, mumps, rubella (MMR) and hepatitis A, and factors associated with the seronegative test results for measles, mumps and hepatitis A at 2 years of age. This was a population-based cohort that addressed health conditions and mother/infant nutrition in Cruzeiro do Sul city, Brazil. Vaccination data were obtained from official certificates of immunization. The children underwent blood collection at the two-year-old follow-up visit; the samples were analyzed using commercially available kits to measure seropositivity for measles, mumps, and hepatitis A. We used modified Poisson regression models adjusted for covariates to identify factors associated with incomplete vaccination and negative serology after vaccination. Out of the 825 children included in the study, adherence to the vaccine was 90.6% for MMR, 76.7% for the MMRV (MMR + varicella), and 74.9% for the hepatitis A vaccine. For MMR, after the adjustment for covariates, factors associated with incomplete vaccination included: white-skinned mother; paid maternity leave; raising more than one child; lower number of antenatal consultations; and attending childcare. For hepatitis A, the factors included: white-skinned mother and not having a cohabiting partner. The factors with statistically significant association with a negative antibody test result included: receiving Bolsa Familia allowance for measles and mumps; incomplete vaccination for measles; and vitamin A deficiency for mumps. Strategies to improve the efficiency of vaccine programs are urgently needed. These include improvements in communication about vaccine safety and efficacy, and amplification of access to primary care facilities, prioritizing children exposed to the sociodemographic factors identified in this study. Additionally, sociodemographic factors and vitamin A deficiency may impact the immune responses to vaccines, leading to an increased risk of potentially severe and preventable diseases. countries addition homogeneous effectiveness study MMR age populationbased population based motherinfant infant city immunization twoyearold two year old followup follow up visit 82 906 90 6 90.6 767 76 7 76.7 varicella, varicella , varicella) 749 74 9 74.9 whiteskinned white skinned leave child consultations childcare partner needed efficacy facilities Additionally vaccines diseases 8 90. 76. 74.

RESUMO OBJETIVO: Investigar a autocorrelação do crescimento linear e ganho de peso do nascimento até a infância considerando a distribuição de escores z de comprimento/estatura e peso por idade e de acordo com a riqueza domiciliar. MÉTODOS: Foram utilizados dados de 614 crianças do Estudo MINA-Brasil com medições antropométricas realizadas do nascimento até os cinco anos de idade. Escores z foram calculados para comprimento/estatura (HAZ) e peso (WAZ) seguindo padrões internacionais. A autocorrelação ou estabilidade da adequação do estado nutricional do nascimento à infância foi estimada por meio de modelos de regressão quantílica para HAZ e WAZ, separadamente, extraindo-se coeficientes e intervalos de confiança de 95% (IC95%) nos quantis 25, 50 e 75. Em uma análise de subgrupo, estimou-se a autocorrelação entre o nascimento até os dois anos de idade, e entre dois e cinco anos de idade. Para investigar disparidades na autocorrelação, termos de interação entre índices de riqueza familiar (ao nascer e aos cinco anos de idade) e escores z de tamanho do recém-nascido foram incluídos nos modelos. RESULTADOS: Os coeficientes de autocorrelação foram significantes e tiveram magnitude semelhante ao longo da distribuição dos índices antropométricos aos cinco anos de idade (HAZ, quantil 50: 0,23, IC95%: 0,11 a 0,35; WAZ, quantil 50: 0,31, IC95%: 0,19 a 0,43). Maior estabilidade do estado nutricional foi observada entre dois e cinco anos, com coeficientes acima de 0,82. Autocorrelação significantemente maior do crescimento linear foi observada entre as crianças de domicílios mais ricos, tanto ao nascer, nos limites inferiores da distribuição HAZ (quantil 25: 0,30, IC95%: 0,13 a 0,56) e durante a infância, em toda a distribuição HAZ aos cinco anos. Para o ganho de peso, observou-se uma autocorrelação mais forte nos limites superiores da distribuição do WAZ aos cinco anos de idade entre as crianças de domicílios mais ricos ao nascer (quantil 75: 0,59, IC95%: 0,35 a 0,83) e durante a infância (quantil 75: 0,54, IC95%: 0,15 a 0,93). CONCLUSÃO: Houve autocorrelação significante de HAZ e WAZ desde o nascimento, com indicação de substancial estabilidade do estado nutricional entre os dois e cinco anos de idade. A autocorrelação diferencial de acordo com a riqueza domiciliar deve ser considerada para o planejamento de intervenções precoces para prevenir a má nutrição.

ABSTRACT Adequate and healthy nutrition is crucial for child development, especially in the first 1,000 days of life. Since unhealthy eating is a modifiable risk factor for diseases and malnutrition, actions that promote the guidelines of the ‘Food guide for Brazilian children under 2 years old’ are necessary. This report shares the process of planning, building, disseminating, offering, and evaluating a virtual workshop for professionals in Primary Health Care in Acre, Western Brazilian Amazon, highlighting the challenges encountered and lessons learned. The workshop had 170 participants and was asynchronous to facilitate access for participants given the low availability of time and instability of the internet signal in the region. The use of different virtual tools favored dialogue between the participants and the workshop coordinators. Participants reported preferring short videos with animations, and the content considered most important addressed anthropometric assessment, food processing and classification, and food challenges. The importance of partnerships with health departments is highlighted for the adequate planning and dissemination of the workshop, and the collaboration of researchers and professionals in the field for the definition and elaboration of relevant content.

RESUMO A alimentação adequada e saudável é crucial para o desenvolvimento infantil, principalmente nos primeiros mil dias de vida. Sendo a alimentação não saudável um fator de risco modificável para doenças e desnutrição, ações que promovam as orientações do ‘Guia alimentar para crianças brasileiras menores de 2 anos’ são necessárias. O presente relato compartilha o processo de planejamento, construção, divulgação, oferecimento e avaliação de uma oficina virtual para profissionais da Atenção Primária à Saúde no Acre, Amazônia Ocidental brasileira, com destaque para os desafios encontrados e as lições aprendidas. A oficina contou com 170 inscritos e foi assíncrona para facilitar o acesso dos participantes diante da baixa disponibilidade de tempo e instabilidade do sinal de internet na região. O uso de diferentes ferramentas virtuais favoreceu o diálogo entre os participantes e as coordenadoras da oficina. Participantes relataram preferir vídeos curtos com animações, e os conteúdos considerados mais importantes abordaram avaliação antropométrica, processamento e classificação de alimentos e desafios da alimentação. Ressalta-se a importância das parcerias com secretarias de saúde para o adequado planejamento e divulgação da oficina, e da colaboração de pesquisadoras e profissionais da área para a definição e elaboração de conteúdo relevante.

Resumo O objetivo deste artigo é analisar a concordância entre dados de peso pré-gestacional, peso na gravidez, altura e pressão arterial sistólica (PAS) e diastólica (PAD) registradas tanto na caderneta da gestante quanto nas informações obtidas no estudo longitudinal MINA-Brasil. Foram selecionadas as gestantes participantes do estudo MINA-Brasil que apresentavam cartão do pré-natal no momento do parto. A análise de concordância dos dados utilizou o coeficiente de correlação de concordância de Lin e análise de Bland-Altman. Foram incluídas 428 gestantes. Houve concordância moderada entre as informações para o peso pré-gestacional autorreferido (0,935) e altura (0,913), e concordância substancial para o peso da gestante no segundo (0,993) e terceiro (0,988) trimestres de gestação. Verificou-se baixa concordância da PAS e PAD no segundo (PAS=0,447; PAD=0,409) e terceiro (PAS=0,436; PAD=0,332) trimestres gestacionais. As medidas antropométricas apresentaram boa concordância. Houve baixa concordância entre as medidas de pressão arterial, que podem estar relacionadas tanto à variabilidade como também à padronização dessas medidas, sugerindo-se necessidade de capacitação e treinamento contínuo das equipes de pré-natal na atenção primária à saúde.

Abstract This article aims to examine agreement of pre-pregnancy weight, pregnancy weight, height and systolic (SBP) and diastolic (DBP) blood pressure measurements recorded on antenatal record cards with the same information obtained in the MINA-Brazil longitudinal study. 428 pregnant women who participated in the MINA-Brazil study and had an antenatal card at time of childbirth were selected. Concordance analysis of the data used Lin’s correlation coefficient and Bland-Altman analysis. There was moderate agreement on self-reported pre-pregnancy weight (0.935) and height (0.913) information, and substantial agreement on the pregnant women’s weight in the second (0.993) and third (0.988) trimesters of pregnancy. Little agreement was found on SBP and DBP measured in the second (SBP = 0.447; DBP = 0.409) and third (SBP = 0.436; DBP = 0.332) trimesters of pregnancy. Anthropometric measurements showed strong agreement. There was weak agreement between blood pressure measurements, which may relate both to the variability and the standardisation of these measurements, suggesting the need for continued training of antenatal teams in primary health care.
