Predictors of excess body weight concurrently affecting mother-child pairs: a 6 year follow-up.

BACKGROUND: We examined the predictors of excess body weight (EBW) concurrently affecting mother-child pairs after delivery during 6 years of follow-up. METHODS: Prospective cohort study conducted on 435 mother-child pairs. Data were collected at four time points: at birth in the maternity hospital; 1-2 years old, 4-5 years old and 6 years old at the participant's home. Poisson regression analysis was used to examine the predictors of maternal-child EBW: mothers with excessive gestational weight gain (GWG) and large-for-gestational age (LGA) baby (>90th percentile) at baseline and mothers with body mass index (BMI) ≥ 25 kg/m2 and a child > 85th percentile. RESULTS: The adjusted analysis showed that the risk of mother-child pairs concurrently having EBW increased with increasing pre-pregnancy BMI (RR = 2.4 and RR = 3.3 for pre-pregnancy BMI 25-30 and ≥30 kg/m2, respectively, P < 0.01). Excessive GWG and LGA infants were also significant predictors of EBW concurrently affecting mother-child pairs (RR = 2.2 and RR = 2.3, respectively, P < 0.01). CONCLUSION: Excessive pre-pregnancy BMI, excessive GWG and LGA status were strong predictors of EBW concurrently affecting mother-child pairs over 6 years of follow-up. Public policies must be established primarily before/during pregnancy to avoid an EBW cycle in the same family over the years.

Foram convidadas para participar do estudo 13 crianças de ambos os sexos entre 5 ­ 12 anos de idade que estavam internadas no ambulatório de oncologia. Considerações Finais: adoção do Termo de Assentimento Livre Esclarecido Lúdico construído mostrou-se efetivo ao alcance do objetivo de sua utilização no contexto ético em pesquisa e avançou no sentido de despertar sobre potencialidade para além da pesquisa e, também, como recurso fundamental para o assentimento das crianças em situações específicas no processo de adoecimento e internação, possibilitando o exercício de direito e compreensão do que está sendo realizado durante seu tratamento.

Objective: report the experience in the construction and applicability of an informed term of consent in a survey of children hospitalized for cancer treatment. Material and method: experience report on the construction and applicability of a free and informed term of consent for conducting a study on the nutritional profile and food and nutrition education of children and adolescents undergoing cancer treatment at a public hospital in Santa Catarina, Brazil. Results: the construction and applicability of the informed term of consent allowed a better understanding of the child prior to conducting the research regarding the steps and phases of data collection, as well as its risks and benefits. It was possible for the child to clarify their doubts and actively participate in the study. Thirteen children of both sexes, aged between 5 - 12 years, hospitalized and in the oncology outpatient clinic, were invited to participate. Final considerations: adoption of the playful free and informed term of consent proved to be effective in reaching the objective of its use in the ethical research context and it has advanced in the sense of raising awareness of the potentiality beyond research, and also as a fundamental resource for the consent of children in specific situations in the illness and hospitalization process, enabling them to exercise their rights and understand what is happening during their treatment.

Predictors of excess birth weight in Brazil: a systematic review / Preditores do excesso de peso ao nascer no Brasil: revisão sistemática

Abstract Objective: To describe the main predictors for excess birth weight in Brazilian children. Data sources: Systematic review carried out in the bibliographic databases: PubMed/MEDLINE, Cochrane, Scopus, Web of Science, and LILACS. The research in the gray literature was performed using the Google Scholar database. The bias risk analysis was adapted from the Downs and Black scale, used to evaluate the methodology of the included studies. Data synthesis: Using the classifications of fetal macrosomia (>4.000 g or ≥4.000 g) and large for gestational age (above the 90th percentile), 64 risk factors for excess birth weight were found in 33 scientific articles in the five regions of the country. Of the 64 risk factors, 31 were significantly associated with excess birth weight, with excess gestational weight gain, pre-gestational body mass index ≥25 kg/m2, and gestational diabetes mellitus being the most prevalent. Conclusion: The main predictors for excess birth weight in Brazil are modifiable risk factors. The implementation of adequate nutritional status in the gestational period and even after childbirth appears to be due to the quality and frequency of the follow-up of the mothers and their children by public health agencies.

Resumo Objetivo: Descrever os principais preditores para o excesso de peso ao nascer em crianças brasileiras. Fontes dos dados: Revisão sistemática feita nos bancos de dados bibliográficos: PubMed/Medline, Cochrane, Scopus, Web of Science e Lilacs. A pesquisa na literatura cinzenta foi feita na base de dados Google Acadêmico. A análise do risco de viés foi adaptada da escala de Downs e Black, usada para avaliar a metodologia dos estudos incluídos. Síntese dos dados: Com o uso das classificações macrossomia fetal (> 4.000 g ou ≥ 4.000 g) e grande para idade gestacional acima do percentil 90, foram encontrados 64 fatores de risco para excesso de peso ao nascer em 33 artigos científicos nas cinco regiões do país. Dos 64 fatores de risco, 31 foram significativamente associados a excesso de peso ao nascer, os mais prevalentes foram ganho de peso gestacional excessivo, índice de massa corporal pré-gestacional ≥25 kg/m2 e diabetes mellitus gestacional. Conclusão: Os principais preditores para o excesso de peso ao nascer no Brasil são fatores de risco modificáveis. O estabelecimento de um estado nutricional adequado no período gestacional e mesmo após o parto parece ser a qualidade e a frequência do acompanhamento dos órgãos de saúde junto às mães e seus filhos.

Breast-feeding duration for the prevention of excess body weight of mother-child pairs concurrently: a 2-year cohort study.

OBJECTIVE: To examine the association between breast-feeding duration and the risk of excess body weight (children >85th percentile, mothers BMI≥25·0 kg/m2) concurrently in mother-child pairs two years after delivery. DESIGN: Prospective cohort study in Joinville, Brazil. Multivariable logistic regression was used to examine the independent relationship between breast-feeding duration and risk of excess body weight. SETTING: Brazilian public maternity hospital. SUBJECTS: Three hundred and five mother-child pairs. RESULTS: At 2-year follow-up, 23·6 % of mother-child pairs had excess body weight. Children breast-fed for <2 months were more likely to have excess body weight than children breast-fed for ≥6 months (OR=2·4; 95 % CI 1·1, 5·1). Breast-feeding for <2 months was also associated with a greater likelihood of maternal excess body weight compared with those who breast-fed for ≥6 months (OR=2·9; 95 % CI 1·1, 8·1). There was a progressive increase in the likelihood of mother-child pairs having excess body weight as breast-feeding duration decreased. In addition to breast-feeding duration, other independent determinants of excess body weight were pre-pregnancy weight, gestational weight gain and number of pregnancies in mothers, and birth weight in children. CONCLUSIONS: Breast-feeding for a longer duration has a parallel protective effect on the risk of excess body weight in mother-child pairs two years after birth. Since members of the same family could be influenced by the same risk factors, continued promotion and support of breast-feeding may help to attenuate the rising prevalence of overweight in mother-child pairs.

Independent effect of type of breastfeeding on overweight and obesity in children aged 12-24 months. / Efeito independente do tipo de aleitamento no risco de excesso de peso e obesidade em crianças entre 12-24 meses de idade.

This study aimed to analyze the effect of type of breastfeeding on the nutritional status of children between 12-24 months of age. This cohort study included 435 children born in 2012 in a public hospital in Joinville, Santa Catarina State, Brazil. Two years after delivery the mothers and their children were contacted in their homes for a new investigation of demographic, economic, nutritional, and anthropometric data. In the unadjusted analysis, children who were not exclusively breastfed were more likely to be overweight (including obesity) at 2 years of age (OR = 1.6; p = 0.049) than exclusively breastfed children. After adjusting for several covariates, children who were not exclusively breastfed had a 12% higher risk of overweight including obesity compared to unadjusted analysis (OR = 2.6 vs. OR = 1.8; p = 0.043). In addition, birthweight was also an independent determinant of overweight including obesity (OR = 2.5; p = 0.002). The practice of exclusive breastfeeding can reduce the risk of overweight in children from developing countries such as Brazil.

Resumo: Este estudo teve como objetivo avaliar a importância do tipo de aleitamento no risco de excesso de peso de crianças entre 12-24 meses de idade. Trata-se de um estudo de coorte que incluiu 435 crianças nascidas em 2012 em uma maternidade pública de Joinville, Santa Catarina, Brasil. Dois anos após o parto, as mães e seus filhos foram contatados nas residências para uma nova coleta de dados. Na análise não ajustada, crianças que não receberam aleitamento materno exclusivo apresentaram maior risco de desenvolver excesso de peso aos dois anos de idade (OR = 1,6; p = 0,049), quando comparadas às crianças amamentadas exclusivamente. Mesmo após o ajuste para diversas covariáveis, o risco das crianças não amamentadas exclusivamente apresentarem excesso de peso aumentou 12% em relação à análise não ajustada (OR = 2,6 vs. OR = 1,8; p = 0,043). Adicionalmente, o peso ao nascer também mostrou ser um determinante independente do risco de excesso de peso (OR = 2,5; p = 0,002). A prática do aleitamento materno exclusivo pode reduzir o risco de excesso de peso em crianças de países em desenvolvimento como o Brasil.

Neck circumference as a complementary measure to identify excess body weight in children aged 13-24 months / Circunferência do pescoço como medida complementar para identificar excesso de peso corporal em crianças de 13-24 meses de idade

To analyze the accuracy of neck circumference (NC) as a measure for assessing excess body weight in children aged 13-24 months of life, according to gender.Methods:this is a cross-sectional study comparing the neck circumferences in relation to body mass index (BMI) and other anthropometric measures. The best cut-off point for identifying excess body weight was determined using the Receiver Operating Characteristics curve (ROC curve), according to gender and age groups 13-15 months, 16-19 months and 20-24 months.Results:NC waspositively correlated (p<0.001) with body weight and BMI in both genders, and length in girls (p<0.001). Positive correlations were found between NC and BMI in the three age groups (13-15, 16-19 and 20-24 months) in both boys and girls. The NC cut-off points for boys were 23.6, 23.9 and 24.0 cm, and 23.4, 23.5 and 23.6 cm for girls, for the 1315, 16-19 and 20-24 age groups respectively.Conclusions:NC can be used to screen for excess body weight in children aged 13-24 months. However, further studies with a larger sample will be required in order to complement these results...
