Fatores associados ao estado nutricional de crianças menores de cinco anos da Paraíba, Brasil / Factors associated with nutritional status of children under five years old from Paraíba, Brazil

Resumo Objetivou-se analisar se o estado nutricional de crianças menores de cinco anos de idade está relacionado às condições biológicas de suas mães, ao acesso a serviços de saúde, ao benefício de programas sociais e às condições socioeconômicas. Trata-se de um estudo transversal realizado no contexto da Estratégia Saúde da Família, em sete municípios do interior do estado da Paraíba. A metodologia incluiu o diagnóstico do déficit de estatura e do excesso de peso (sobrepeso e obesidade) das crianças, cujos determinantes foram analisados por meio de árvore de decisão. Como resultado, foram avaliadas 469 crianças, das quais 7,9% apresentaram déficit de estatura e 12,8% excesso de peso. Encontrou-se associação desses desfechos com o estado nutricional materno. A baixa estatura também teve como exposições relevantes a idade da criança inferior a dois anos (p = 0,018) e a insegurança alimentar e nutricional moderada/grave (p = 0,008). Para o excesso de peso, não ser beneficiário do Programa Bolsa Família (p = 0,049) e a pior situação socioeconômica (p = 0,006) também representaram fatores associados ao desfecho. Como conclusão do presente estudo, podemos afirmar que existe uma associação entre o estado nutricional materno e o da criança.

Abstract This paper aimed to analyze whether the nutritional status of children under 5 years of age is related to the biological conditions of their mothers, access to health services, the benefit of social programs, and socioeconomic conditions. This is a cross-sectional study carried out in the context of the Family Health Strategy in seven municipalities in inland Paraíba State. The methodology included the diagnosis of stunting and excess weight (overweight and obesity) in children, which determinants were analyzed through the Decision Tree. As a result, 469 children were evaluated, of which 7.9% had stunting and 12.8% had excess weight. An association of these outcomes was found with maternal nutritional status. Also, the relevant exposures of stunting were the age of the child of less than 2 years (p = 0.018) and the moderate/severe food and nutritional insecurity (p = 0.008). For excess weight, not being a beneficiary of the Programa Bolsa Família (p = 0.049) and the worst socioeconomic situation (p = 0.006) were also factors associated with the outcome. As a conclusion of the present study, we can affirm that there is an association between the maternal and child nutritional status.

Prevalence and determinants of stunting among preschool and school-going children in the flood-affected areas of Pakistan / Prevalência e determinantes da baixa estatura entre crianças em idade pré-escolar e em idade escolar nas áreas afetadas pelas enchentes do Paquistão

Stunting is a significant public health problem in low- and middle-income countries. This study assessed the prevalence of stunting and associated risk factors of stunting among preschool and school-going children in flood-affected areas of Pakistan. A cross-sectional study was conducted by visiting 656 households through multi-stage sampling. Respondent's anthropometric measurements, socio-demographic information and sanitation facilities were explored. A logistic regression model was used to determine determinants of stunting, controlling for all possible confounders. The overall prevalence of stunting in children was 40.5%, among children 36.1% boys and 46.3% of girls were stunted. The prevalence of stunting in under-five children was 50.7%. Female children (OR=1.35, 95% CI:0.94-2.0), children aged 13-24 months (OR=6.5, 95% CI: 3.0-13.9), mothers aged 15-24 years (OR=4.4, 95% CI: 2.6-7.2), joint family (OR=2.1, 95% CI: 1.4-3.0) did not have access to improved drinking water (OR=3.3, 95% CI: 1.9-5.9), and the toilet facility (OR=2.8, 95% CI, 1.9-4.3), while the children from district Nowshera (OR=1.7, 95% CI: 0.9-3.2) were significantly (P<0.05) associated in univariate analysis. The regression model revealed that child age, maternal age, family type, quality of water, and toilet facility, were the significant (P<0.05) factors contributing to child stunting in the flood-hit areas. Identification of key factors might be helpful for policymakers in designing comprehensive community-based programs for the reduction of stunting in flood-affected areas. In disasters such as flood, the detrimental consequences of the stunting problem could be even more on children. Evidence-based education and care must be provided to the families in the flood-affected regions to reduce the stunting problem. The determinants of stunting should be targeted by making comprehensive policies regarding proper nutrition, livelihood, clean water, and sanitation facilities in flood-hit regions.

A baixa estatura é um problema significativo de saúde pública em países de baixa e média renda. Este estudo avaliou a prevalência de nanismo e os fatores de risco associados de nanismo entre crianças em idade pré-escolar e em idade escolar em áreas afetadas por inundações do Paquistão. Foi realizado um estudo transversal visitando 656 domicílios por meio de amostragem em múltiplos estágios. As medidas antropométricas do entrevistado, informações sociodemográficas e instalações de saneamento foram exploradas. Um modelo de regressão logística foi usado para determinar os determinantes do nanismo, controlando todos os possíveis fatores de confusão. A prevalência geral de baixa estatura em crianças foi de 40,5%, entre as crianças 36,1% dos meninos e 46,3% das meninas com baixa estatura. A prevalência de baixa estatura em crianças menores de 5 anos foi de 50,7%. Crianças do sexo feminino (OR = 1,35, IC de 95%: 0,94-2,0), crianças de 13-24 meses (OR = 6,5, IC de 95%: 3,0-13,9), mães de 15-24 anos (OR = 4,4, IC de 95%: 2,6-7,2), família conjunta (OR = 2,1, IC 95%: 1,4-3,0) não tiveram acesso a água potável de qualidade (OR = 3,3, IC 95%: 1,9-5,9) e a banheiro (OR = 2,8, IC de 95%, 1,9-4,3), enquanto as crianças do distrito de Nowshera (OR = 1,7, IC de 95%: 0,9-3,2) foram significativamente (P < 0,05) associadas na análise univariada. O modelo de regressão revelou que a idade da criança, idade materna, tipo de família, qualidade da água e banheiro foram os fatores significativos (P < 0,05) que contribuíram para a baixa estatura infantil nas áreas afetadas pelas enchentes. A identificação de fatores-chave pode ser útil para os formuladores de políticas no planejamento de programas comunitários abrangentes para a redução da baixa estatura em áreas afetadas pelas enchentes. Em desastres como enchentes, as consequências prejudiciais do problema de baixa estatura podem ser ainda maiores para as crianças. Educação baseada em evidências e cuidados deve ser fornecida às famílias nas regiões afetadas pelas enchentes para reduzir o problema de nanismo. Os determinantes do retardo de crescimento devem ser almejados pela formulação de políticas abrangentes sobre nutrição adequada, meios de subsistência, água potável e instalações de saneamento nas regiões afetadas pelas enchentes.

Dietary patterns in Mexican preschool children are associated with stunting and overweight

ABSTRACT OBJECTIVE To evaluate the association between dietary patterns, stunting, and overweight among Mexican preschoolers. METHODS This study was conducted with anthropometric (weight, height/length), sociodemographic (age, gender, education level of household head, socioeconomic status, country region and area, ethnicity, and beneficiary of social programs), and dietary data (Semiquantitative-food frequency questionnaire) on children aged from 1 to 4 years collected from the Mexican National Health and Nutrition Survey-2012. Dietary patterns were derived by principal components analysis. The association between dietary patterns, stunting, and overweight was assessed by prevalence ratios (PR), estimated by Poisson regression. RESULTS In total, 1,112 preschoolers (mean age 3.06 years, SD = 1.08 years; 48.8% females) were included in the study; 11.9% of whom presented stunting, and 6.7% overweight. We identified four dietary patterns: Fruits and Vegetables [F&V], Western [W], Traditional [T], and Milk and Liquids [M&L]. Considering the lowest tertile of each dietary pattern as reference, the prevalence of stunting was 2.04 times higher [95%CI: 1.17-3.56] among children in the highest tertile of the "F&V" pattern. The prevalence of stunting was lower among children in the highest tertile of the "W" pattern [PR = 0.48; 95%CI: 0.27-0.85]. Overweight was negatively associated with the "F&V" dietary pattern [PR = 0.37; 95%CI: 0.16-0.85 for its highest tertile], and children whose consumption was mostly equivalent to the "T" pattern showed higher prevalence of stunting [PR = 1.74; 95%CI: 1.01-3.00]. CONCLUSIONS The prevalence of stunting and overweight in a nationwide sample of Mexican preschoolers was associated with dietary patterns.

Estado nutricional e fatores associados ao déficit estatural em crianças menores de cinco anos de comunidades remanescentes de quilombos do Nordeste brasileiro / Nutritional status and factors associated with stunting in children under five years of age in maroon communities in Northeast Brazil / Estado nutricional y factores asociados al déficit de estatura en niños menores de cinco años originarios de comunidades reminiscentes de quilombos en el Nordeste Brasileño

Resumo: Os quilombolas constituem parte das minorias étnico-raciais do país que apresentam iniquidades em saúde, reflexo de um processo histórico de grandes desvantagens socioeconômicas. O objetivo foi avaliar o estado nutricional e fatores associados ao déficit estatural em crianças quilombolas menores de cinco anos residentes em comunidades quilombolas tituladas na Região Nordeste do Brasil. Utilizaram-se dados secundários provenientes da Pesquisa de Avaliação da Situação de Segurança Alimentar e Nutricional em Comunidades Quilombolas Tituladas (2011). Os desfechos de interesse foram o déficit estatural (estatura-para-idade < -2z), excesso de peso (peso-para-estatura > 2z) e o déficit ponderal (peso-para-idade < -2z). Foi empregado o teste qui-quadrado para avaliar a significância das diferenças entre as prevalências. A análise multivariada considerou um modelo conceitual hierárquico sobre o déficit estatural. As prevalências de excesso de peso e déficit ponderal foram 2,8% e 6,1%, respectivamente. O déficit estatural foi diagnosticado em 14,1% da amostra. O modelo hierárquico de déficit estatural evidenciou maiores prevalências do agravo entre crianças que não tinham acesso à atenção básica (RP = 1,63; IC95%: 1,11; 2,41), à água tratada (RP = 2,09; IC95%: 1,42; 3,08) e que nasceram com baixo peso (RP = 2,19; IC95%: 1,33; 3,61). A elevada prevalência de déficit estatural mostra que a população quilombola no Nordeste apresenta condições de saúde desfavoráveis, sendo reflexo da falta de acesso à atenção básica e das precárias condições de saneamento.

Abstract: Quilombolas, or members of maroon communities in Brazil, are part of the country's ethnic/racial minorities exposed to health inequities, reflecting a historical process of harsh socioeconomic disadvantages. The study aimed to assess nutritional status and factors associated with stunting in quilombola children under five years of age living in land-deeded quilombola communities in Northeast Brazil. The study used secondary data from the Survey on Food and Nutritional Security in Land-Deeded Quilombola Communities (2011). The target outcomes were stunting (height-for-age < -2z), excess weight (weight-for-height > 2z), and underweight (weight-for-age < -2z). Chi-square test was used to assess the significance of differences between prevalence rates. Multivariate analysis used a hierarchical conceptual model on stunting. Prevalence rates for excess weight and underweight were 2.8% and 6,1%, respectively. Stunting was diagnosed in 14.1% of the sample. The hierarchical model for stunting evidenced higher prevalence rates among children without access to primary healthcare (PR = 1.63; 95%CI: 1.11; 2.41) and safe water (PR = 2.09; 95%CI: 1.42; 3.08) and those with a history of low birthweight (PR = 2.19; 95%CI: 1.33; 3.61). The high prevalence of stunting showed that the quilombola' population in the Northeast experiences unfavorable health condition, reflecting lack of access to primary healthcare and precarious sanitation.

Resumen: Los quilombolas constituyen parte de las minorías étnico-raciales del país que presentan inequidades en salud, reflejo de un proceso histórico que implicó grandes desigualdades socioeconómicas. El objetivo del trabajo fue evaluar el estado nutricional y los factores asociados con el déficit de estatura en niños quilombolas, menores de 5 años, residentes en comunidades quilombolas, ubicadas en la Región Nordeste del Brasil. Se utilizaron datos secundarios provenientes de la Pesquisa de Avaliação da Situação de Segurança Alimentar e Nutricional em Comunidades Quilombolas Tituladas (2011). Los resultados de interés fueron: déficit de estatura (estatura-para-edad < -2z), exceso de peso (peso-para-estatura > 2z) y insuficiencia ponderal (peso-para-edad < -2z). Se empleó la prueba chi-cuadrado para evaluar la significancia de las diferencias entre las prevalencias. El análisis multivariado consideró un modelo conceptual jerárquico sobre la insuficiencia de estatura. Las prevalencias de exceso de peso y déficit ponderal fueron 2,8%, 6,1%, respectivamente. El déficit de estatura fue diagnosticado en un 14,1% de la muestra. El modelo jerárquico de déficit de estatura evidenció mayores prevalencias de enfermedades entre niños que no tenían acceso a la atención básica (RP = 1,63; IC95%: 1,11; 2,41), al agua tratada (RP = 2,09; IC95%: 1,42; 3,08) y que nacieron con bajo peso (RP = 2,19; IC95%: 1,33; 3,61). La elevada prevalencia de déficit de estatura muestra que la población quilombola en el Nordeste presenta condiciones de salud desfavorables, siendo reflejo de la falta de acceso a la atención básica en salud y de las precarias condiciones de saneamiento.

Resumen: Objetivo: Estimar las prevalencias municipales de mala nutrición en población preescolar en México, y describir su variabilidad y su relación con la cobertura del Programa Nacional México Sin Hambre. Material y métodos: A partir de datos de la Encuesta Nacional de Salud y Nutrición de 2012, la desigualdad del ingreso y marginación municipal se aplicó un modelo normal generalizado para obtener las distribuciones municipales de los indicadores de nutrición y estimar las prevalencias de mala nutrición. Resultados: Las prevalencias de talla baja variaron de 7.8% (IC95%: 5.9-8.9) a 64.2% (49.2-72.5), las de bajo peso de 0.6% (0.005-1.7) a 22.2% (13.5-34.9) y de sobrepeso u obesidad de 2.6% (0.2-3.9) a 14.4% (11.9-27.7). De los 554 municipios con prevalencias de talla baja mayor que 25%, 275 fueron cubiertos por el programa México Sin Hambre. Conclusiones: La estimación de prevalencias municipales de mala nutrición evidenció grandes diferencias al interior del país, mismas que podrían asistir la política pública.

Abstract: Objective: To estimate malnutrition prevalence of preschool children at the level of municipality in Mexico, describe prevalence heterogeneity and its relationship with the Programa Nacional México Sin Hambre´s coverage. Materials and methods: Using the 2012 Mexican National Survey of Health and Nutrition, municipal income inequality and marginality, we applied a generalized normal model to obtain municipal distributions of nutrition status indicators from which we estimated malnutrition prevalence. Results: Stunting prevalence ranged from 7.8% (95%CI: 5.9-8.9) to 64.2% (49.2-72.5), low weight prevalence ranged from 0.6% (0.005-1.7) to 22.2% (13.5-34.9) and overweight-obesity prevalence ranged from 2.6% (0.2-3.9) to 14.4% (11.9-27.7). A total of 275 out of 554 municipalities with stunting prevalence above 25% were covered by the Programa Nacional México Sin Hambre. Conclusions: Municipal malnutrition prevalence estimation showed wide differences within Mexico; this knowledge could assist public policy.

Desnutrición crónica en población infantil de localidades con menos de 100 000 habitantes en México / Stunting in children population in localities under 100 000 inhabitants in Mexico

Resumen: Objetivo: Describir la prevalencia de desnutrición infantil y algunas características sociodemográficas asociadas con la desnutrición crónica en menores de cinco años, de localidades de menos de 100 000 habitantes en 2012 y 2018 en México. Material y métodos: Se calcularon prevalencias de bajo peso, desnutrición crónica y emaciación. Se presenta la comparación de la desnutrición crónica por variables sociodemográficas y de diversidad dietética. Se probaron modelos logísticos multivariados entre desnutrición crónica y variables sociodemográficas. Resultados: En 2018, 4.4% presentó bajo peso, 14.9% desnutrición crónica y 1.5% emaciación. La desnutrición crónica fue mayor en hogares indígenas (24.5%), hogares de mayores carencias socioeconómicas (17.5%) y hogares con inseguridad alimentaria moderada/severa (15.3%). La desnutrición crónica se asoció positivamente con habitar hogar indígena y la alta diversidad dietética resultó factor protector de desnutrición crónica. Conclusiones: Se documenta una alta prevalencia de desnutrición crónica asociada con condiciones de alta marginalidad. Es importante fortalecer estrategias diseñadas para contener la desnutrición, sobre todo en las poblaciones de mayores carencias sociales.

Abstract: Objective: To describe the undernutrition prevalence, as well as some sociodemographic characteristics associated to stunting in children under five years old, living on localities with less than 100 000 inhabitants in Mexico in 2012 and 2018. Material and methods: Low weight, stunting and wasting prevalences were calculated in children under 5y according to WHO Growth Reference. A comparison of stunting by sociodemographic and diet diversity variables is presented. Multi-variated logistic models between chronic malnutrition and sociodemographic variables were calculated. Results: In 2018, 4.4% of the individuals suffered low weight, 14.9% stunting and 1.5 % wasting. Stunting was greater in indigenous households (24.5%), households from the lower socioeconomic-index tertile (17.5%), and households with moderated/severe food insecurity (15.3%). Stunting was positively associated with indigenous condition; on the other hand a highly diverse diet resulted to be a protective factor against it. Conclusions: A high prevalence of chronical malnutrition was documented associated with high poverty conditions. It is important to enforce strategies aimed to contain it, mainly in such populations with greater social deprivation.

Associação de baixa estatura severa em crianças indígenas Yanomami com baixa estatura materna: indícios de transmissão intergeracional / Association of severe stunting in indigenous Yanomami children with maternal short stature: clues about the intergerational transmission

Resumo O objetivo do estudo foi avaliar o estado nutricional de crianças e mulheres indígenas Yanomami e elucidar fatores associados. Estudo transversal, realizado em 17 aldeias, em 2014. Para a avaliação do estado nutricional utilizou-se as curvas de crescimento de 2006 e os escores-Z (ESZ) de estatura/idade (E/I), peso/idade (P/I), peso/estatura (P/E), os quais foram gerados nos programas WHO-Anthro e WHO-AnthroPlus. Estatura inferior a 145cm foi o descritor de baixa estatura materna nas > 18 anos. A regressão de Poisson e as análises estatísticas foram efetuadas no software R, versão 3.1.2. Nos < 5 anos a prevalência de baixa E/I foi 83,8%, de baixo P/I 50%, de baixo P/E 5,4% e de sobrepeso 2,7%. Em 59,5% das crianças observou-se muito baixa E/I e em 68,1% das mães baixa estatura. As crianças de 36-59 meses apresentaram maior risco de baixa estatura severa, em comparação com as de 0,1-23 (RP = 1,3; IC 95%: 1,1-2,3), assim como os filhos de mães com estatura < 145cm, em relação aos filhos de mães com estatura > 144cm (RP = 2,1; IC 95%;1,2-3,6). As alarmantes prevalências de baixa estatura severa revelam a grave situação nutricional das crianças. Já a associação de baixa estatura severa nas crianças e baixa estatura materna reflete o caráter intergeracional do problema.

Abstract This study evaluates the nutritional status of children and women of an indigenous Yanomamigroup, and seeks to clarify associated factors. It was a cross-sectional study, carried out in 17 villages, in 2014. For evaluation of nutritional status we used 2006 growth standards to assign height-for-age (stunting)Z-scores (Z), weight-for-age Z (underweight) and weight-for-height Z (wasting and overweight), using the software WHO-Anthro and WHO-AnthroPlus. Short stature (SS) was defined as values lower 145cm for mothers over the age of 18. The Poisson regression was made in R software. Among children under 60 months the prevalences were: stunting 83.8%; underweight 50%; wasting 5.4%; and overweight 2.7%. In 59.5% of the children there was severe stunting, and 68.1% of the mothers were SS. Prevalence ratio (PR) for severe stunting was higher in age group 36-59 months, in comparison with age group 0.1-23 (PR = 1.3; CI 95%: 1.1-2.3), as did also children of mothers with SS, when compared to the children of mothers without SS (PR = 2.1; CI 95%; 1.2-3.6). The alarming rates of stunting and severe stunting reveal the seriousness of the nutritional situation children. The association of severe stunting in infants and in mothers reflects the intergenerational nature of the problem.

Fatores associados ao excesso de peso e baixa estatura em escolares nascidos com baixo peso / Factors associated with excess weight and stunting in schoolchildren born with low birth weight

Resumo O objetivo deste artigo é avaliar a condição nutricional de crianças com baixo peso ao nascer (BPN) e possíveis associações com variáveis independentes maternas, sexo e antecedentes neonatais Estudo transversal com 544 escolares com BPN (5 a 10 anos de idade) da região metropolitana de São Paulo. Variáveis: dados neonatais das declarações de nascidos vivos (peso ao nascer e idade gestacional), informações sobre a gestação e a condição nutricional atual das mães. A avaliação da condição nutricional dos escolares foi realizada por meio da obtenção dos dados de peso e estatura utilizados cálculo do escore z da estatura/idade (ZEI) e índice de massa corporal (ZIMC). Observou-se baixa estatura; sobrepeso e obesidade em 6,2%, 8,6% e 12,3% das crianças avaliadas, respectivamente. A presença de baixa estatura nos escolares associou-se com estatura materna < 150 cm (OR = 6,94; IC95% 2,34-20,6). O sobrepeso/obesidade nas crianças com BPN associou-se de forma independente com o sobrepeso/obesidade da mãe (OR = 2,40; IC95% 1,44-4,01) e o sexo masculino (OR = 1,77; IC95% 1,06-2,95). Um quinto dos escolares com BPN apresentaram excesso de peso, que se associou à condição nutricional materna atual e ao gênero masculino; a baixa estatura associou-se à estatura materna.

Abstract The scope of this study is to assess the nutritional status of low birth weight (LBW) children and the possible associations with independent maternal variables, gender and neonatal history. It involved a cross-sectional study with 544 LBW schoolchildren (five to ten years of age) in the metropolitan area of São Paulo. Variables: the neonatal data of liveborn infant declarations and the current weight and height of the mothers were collected. The weight and stature used to calculate the height/age z (HAZ) score and the body mass index (BMI) of children were evaluated. Among the LBW children 6.2% were of short stature, 12.3% overweight and 8.6% obese. There was an association between short stature in LBW schoolchildren and short maternal stature < 150 cm (OR = 6.94; 95 % CI 2.34-20.6). Excess weight/obesity in LBW children was independently associated with overweight/obesity of the mother (OR = 2.40; 95% CI 1.44-4.01), and the male gender (OR = 1.77; 95% CI 1.06-2.95). A fifth of schoolchildren with low birth weight were overweight, which was associated with current maternal nutritional status and the male gender and stunting was associated with maternal stature.

Children from a rural region in The Chiapas Highlands, Mexico, show an increased risk of stunting and intestinal parasitoses when compared with urban children / Alto riesgo de desmedro y parasitosis intestinal en niños de una región rural de los Altos de Chiapas, México, en comparación con niños de una región urbana

Abstract Background: The state of Chiapas has held the first place of extreme poverty in Mexico. The majority of Chiapas' municipalities are inhabited by marginalized, indigenous populations, who usually present diarrhea of unknown etiology. We evaluated the nutritional status, intestinal parasites, and common bacterial pathogens, including DEC (diarrheagenic Escherichia coli) strains, in 178 children under five years of age with a high (rural) and a moderate (urban) degree of marginalization. Methods: Z-scores for anthropometric indexes from the children were obtained, whereas intestinal parasites were investigated by using a direct coproparasitoscopic analysis and a concentration method. DEC strains were detected by polymerase chain reaction (PCR). Results: The stunting prevalence in children from the rural and urban regions was 79.8 and 7.5%, respectively. Only children from rural municipalities were parasitized (72.6%), being Ascaris lumbricoides and Entamoeba histolytica/Entamoeba dispar the most prevalent parasites (57.1 and 38.1%, respectively). More than half of the children presented moderated ascariasis. Besides Giardia intestinalis, these parasites were associated with stunting. The prevalence of DEC strains was similar in both regions. Conclusions: Only children from the Chiapas Highlands (rural zone) exhibited high prevalences of stunting and intestinal parasites. A reevaluation of social development programs should be in place to address stunting and intestinal parasitoses, mainly in rural regions of Chiapas, to avoid adverse functional consequences on these children.

Resumen Introducción: El estado de Chiapas ha ostentado el primer lugar de pobreza extrema en México. La mayor parte de la población de los municipios de Chiapas es indígena, vive en condiciones de marginación y padece de diarrea de etiología desconocida. Este trabajo evaluó el estado nutricional, la presencia de parásitos intestinales y patógenos bacterianos comunes, además de cepas DEC (Escherichia coli diarreogénica) en 178 niños menores de cinco años, provenientes de una localidad con alto grado de marginación (rural) y de una con moderada marginación (urbana). Métodos: Se obtuvieron los puntajes Z de los índices antropométricos de los niños. Los parásitos intestinales se investigaron con el método coproparasitoscópico directo y un método de concentración. Las cepas DEC se detectaron mediante reacción en cadena de la polimerasa. Resultados: La prevalencia de desmedro en niños de la zona rural y urbana fue de 79.8 y 7.5%, respectivamente. Únicamente los niños de la zona rural estuvieron parasitados (72.6%), y los más prevalentes fueron Ascaris lumbricoides y Entamoeba histolytica/Entamoeba dispar (57.1 y 38.1%, respectivamente). Más de la mitad de los infantes exhibieron ascariasis moderada. Estos parásitos, además de Giardia intestinalis, se asociaron con el desmedro. En ambas regiones, la prevalencia de DEC fue similar. Conclusiones: Solo los niños de los Altos de Chiapas (zona rural) exhibieron alta prevalencia de desmedro y parásitos intestinales. Para evitar las consecuencias adversas entre los infantes, es necesario reevaluar los programas de desarrollo social para combatir el desmedro y la parasitosis intestinal, principalmente en las regiones rurales de Chiapas.

Prevalence and associated factors of undernutrition among school adolescents in Gobu Seyo District, East Wollega Zone, Oromia regional state of West Ethiopia, 2016

Adolescence is the transitional period between childhood and adulthood. During this, nutrient needs are greatest. There is so little data on adolescents' nutrition and research needs are immense. The objective of the study was to assess prevalence and associated factors of undernutrition in school adolescents aged 10 to 19 years. A cross-sectional study was conducted at GobuSeyo district in December, 2016. Using multi-stage sampling technique and interviewer administered questionnaire data was collected from 640 adolescents. Statistical package for social science version 20 for data entry and analysis and World health organization Anthroplus for determination of nutritional status of adolescents were used. Multivariable logistic regression analysis was used to identify independent predictors. Prevalence of stunting and underweight composed 17.0 and 18.8% respectively. Adolescents who were stunted and underweight were 22.9%. Severely stunted and underweight adolescents were 1.7 and 2.8% respectively. Single predictor of stunting was fathers' occupation (Adjusted odds ratio-AOR- 5.82; 95%; CI-1.15, 29.38). Sex and age of the respondents and fathers' occupation were significant predictors of undernutrition. Thus, adolescent nutrition program focusing on age and sex of adolescents needs to be designed and implemented to address nutritional problem specifically in the study area

Temporal trends in the nutritional status of women and children under five years of age in sub-Saharan African countries: ecological study

ABSTRACT BACKGROUND: While the global prevalence of obesity is rapidly increasing, this pandemic has received less attention in sub-Saharan Africa, particularly in the light of the persistent undernutrition that exists in the context of maternal and child health. We aimed to describe obesity trends among women of childbearing age over recent decades, along with trends in over and undernutrition among children under five years of age, in sub-Saharan African countries. DESIGN AND SETTING: Ecological study with temporal trend analysis in 13 sub-Saharan African countries. METHODS: This was a description of temporal trends in nutritional status: adult obesity, childhood overweight, low height-for-age (stunting), low weight-for-height (wasting), low weight-for-age (underweight) and low birth weight. Publicly available data from repeated cross-sectional national surveys (demographic and health surveys and multiple-indicator cluster surveys) were used. We chose 13 sub-Saharan African countries from which at least four surveys conducted since 1993 were available. We investigated women aged 15-49 years and children under five years of age. RESULTS: In multilevel linear models, the prevalence of obesity increased by an estimated 6 percentage points over 20 years among women of childbearing age, while the prevalence of overweight among children under 5 years old was stable. A major decrease in stunting and, to a lesser extent, wasting accompanied these findings. CONCLUSIONS: The upward trend in obesity among women of childbearing age in the context of highly prevalent childhood undernutrition suggests that the focus of maternal and child health in sub-Saharan Africa needs to be expanded to consider not only nutritional deficiencies but also nutritional excess.

Cómo intervenir y prevenir el retraso del crecimiento en niños menores de cinco años de hogares incluidos en el Sisbén de Caldas / How to intervene and prevent stunting of children from homes belonging to the Sisbén in Caldas

Resumen Introducción. El retraso del crecimiento o la desnutrición crónica (baja estatura para la edad) indica un fracaso en el logro del potencial genético con el que nacemos. Objetivo. Estimar modelos predictivos de retraso del crecimiento en hogares con menores de cinco años en el departamento de Caldas, inscritos en el Sistema de Identificación de Potenciales Beneficiarios de Programas Sociales (Sisbén). Materiales y métodos. Se hizo un estudio analítico en todos los hogares (N=56.987) incluidos en la base de datos del Sisbén III con presencia de menores de cinco años (N=33.244). Las variables estudiadas fueron las características demográficas y socioeconómicas, el acceso a la salud, la vivienda, la pobreza, la educación, el mercado laboral y el retraso del crecimiento. El análisis multivariado se realizó en dos fases: en la primera, se llevó a cabo un análisis exploratorio en los hogares mediante un análisis de clasificación jerárquica (conglomerado) y, luego, se estimó un modelo no lineal predictivo (probit) con el retraso del crecimiento como variable dependiente. Resultados. La mayor proporción de retraso del crecimiento en los menores de cinco años se encontró en la subregión Centro Sur, en la cabecera municipal y en los hogares con ingresos menores de USD$65 mensuales. Conclusión. La pobreza de los hogares caldenses con jefatura femenina en los que viven los menores de cinco años inscritos en el Sisbén, es el mayor predictor de su retraso en el crecimiento.

Abstract Introduction: Growth retardation or chronic malnutrition (low height for age) indicates a failure in the natural genetic potential that allows us to growth. Objective: To estimate predictive models of growth retardation in households with children younger than five years in the department of Caldas and registered in the identification system of potential beneficiaries of social programs ( Sistema de Identificación de Potenciales Beneficiarios de Programas Sociales, Sisbén ). Materials and methods: We conducted an analytical study in all households (N=56,987) included in the Sisbén III database with the presence of children younger than five years (N=33,244). The variables under study were demographic and socioeconomic characteristics, health service access, housing, poverty, education, job market, and growth retardation. The multivariate analysis was done in two phases: first, an exploratory analysis of households using hierarchical classification (cluster), then estimation of a nonlinear predictive model (probit) with growth retardation as the dependent variable. Results. The largest proportion of growth retardation in children younger than five years was found in southcentral Caldas, in urban centers, and households with monthly income lower than USD$ 65. Conclusion. Poverty in Caldas women-headed households with children younger than five years registered in the Sisbén was the main predictor of growth retardation.

Hospitalização por doenças infecciosas, parasitismo e evolução nutricional de crianças atendidas em creches públicas / Hospitalization for infectious diseases, parasitism and nutritional evolution of children attended in public child day care centers

Resumo O objetivo deste artigo é analisar a influência das hospitalizações por doenças infecciosas (diarreia e pneumonia) e do parasitismo na evolução nutricional, ao longo de um ano, entre crianças assistidas em creches públicas municipais. Mães de crianças de uma coorte responderam sobre a hospitalização por diarreia e pneumonia, assim como em relação ao parasitismo, durante o período de um ano de frequência à creche. Medidas antropométricas foram tomadas em cada visita. Usou-se modelo ajustado para examinar a relação entre a experiência de processos infecciosos e os desfechos do crescimento (peso e estatura). Numa amostra de 269 crianças monitoradas no período de 12 meses, a hospitalização por pneumonia e a infecção parasitária estiveram associadas com o crescimento desacelerado do peso e da estatura. Infecções parasitárias e pneumonia associaram-se ao comprometimento do crescimento em termos de peso e estatura.

Abstract The scope of this article is to analyze the influence of hospitalizations by infectious diseases (diarrhea and pneumonia) and parasitism in nutritional evolution, over the period of a year, among children enrolled in municipal public day care centers. Mothers of children in a cohort were asked about previous hospitalization due to diarrhea and pneumonia, as well as in relation to the elimination of worms, during the period of one year of attendance at day care centers. Anthropometrics were measured at each visit. An adjusted model to examine the relationship between infections experienced and growth outcomes (weight and height) was applied. In a subset analysis of 269 children followed up at every visit over the course of 12 months, hospitalization due to pneumonia and parasite infection were associated with decelerated growth in weight and height. Parasitic infection and pneumonia were associated with growth impairment in terms of weight and height.

Diagnóstico nutricional en lactantes menores con cardiopatía congénita: comparación de dos clasificaciones antropométricas / Nutritional assessment in infants with congenital heart disease: comparison of two anthropometric classifications

INTRODUCCIÓN: Los niños con cardiopatía congénita (CC) presentan alto porcentaje de malnutrición por déficit, siendo difícil la interpretación de su estado nutricional. OBJETIVO: Describir el estado nutricional de lactantes con CC utilizando dos clasificaciones antropométricas y realizar una comparación entre ellas. PACIENTES Y MÉTODO: Estudio de cohorte no concurrente. Se estudiaron menores de 12 meses sometidos a cirugía de CC. Se excluyeron prematuros, pequeños para la edad gestacional, portadores de síndrome genético u otra enfermedad con compromiso nutricional. Se registraron datos demográficos, diagnóstico de CC, peso y talla de ingreso. Se realizó evaluación nutricional comparando estándares OMS según clasificación norma ministerial (CNM) y una Clasificación Antropométrica Integrada (CAI) que define desnutrición si (ZT/E)≤-2 y/o (ZP/T)≤-2, riesgo de desnutrición ZP/T entre -1 a -1,9, eutrofia ZP/T entre -0,9 a +0,9, sobrepeso entre +1 a +1,9 y obesidad ZP/T≥+2. RESULTADOS: Se incluyeron 387 intervenciones, 219 (56,6%) varones, mediana de edad 3,1 meses (RIC:0,4;6,4). Un 26,4% tenían talla baja. Utilizando CNM 55 sujetos presentaron dos diagnósticos por superposición de ZP/E y ZP/T, con CAI no hubo superposición. Al comparar CNM con CAI se encontró diferencia en desnutrición 28,9% versus 38,5%(p = 0,001), riesgo de des nutrición 27,4% versus 16,3%(p = 0,01) y obesidad 4,9% versus 3,3%(p = 0,03) respectivamente. Se encontró correlación entre ZP/E y ZP/T, r = 0,6(p < 0,001) y entre ZP/E y ZT/E, r = 0,6(p < 0,001). Conclusiones: Los niños con CC presentan alto porcentaje de desnutrición y talla baja. Utilizando las mismas mediciones antropométricas CAI no presentó superposición de diagnósticos y detectó más desnutrición. El P/E es útil como tamizaje, pero insuficiente en malnutrición crónica.

INTRODUCTION: Children with congenital heart disease (CHD) present a high percentage of undern utrition and the interpretation of their nutritional assessment is difficult. OBJECTIVE: To describe the nutritional status of infants with CHD using two anthropometric classifications and compare them. PATIENTS AND METHOD: Non-concurrent cohort study. We studied children under 12 months under going cardiac surgery. We excluded preterm infants, small for gestational age, carriers of genetic syndrome or other disease with nutritional compromise. Demographic data, type of CHD, weight and height were recorded. Nutritional assessment was performed using WHO standards per health ministry criteria (HMC) and per an Integrated Anthropometric Classification (IAC), which defines undernutrition if height-for-age Z-score (ZT/E)≤-2 and/or weight-for-height (ZP/T)≤-2, risk of un dernutrition as ZP/T between -1 to -1,9, normal as ZP/T between -0.9 to +0.9, overweight as ZP/T between +1 to +1.9 and obesity as ZP/T≥+2. RESULTS: 387 interventions were included, 219 (56.6%) were males, median age 3.1 months (IQR:0.4;6.4). A 26.4% presented short stature. Using HMC classification 55 subjects presented two diagnoses by overlap of ZP/E and ZP/T, although with IAC there was no overlap. Comparing HMC with IAC, a difference was found in undernutrition, 28.9% versus 38.5% (p = 0.001), risk of undernutrition 27.4% versus 16.3%(p = 0.01) and obesity 4.9% ver sus 3.3% (p = 0.03) respectively. Correlation was found between ZP/E and ZP/T, r = 0.6(p < 0.001) and between ZP/E and ZT/E, r = 0.6 (p < 0.001). CONCLUSIONS: Children with CHD have a high per centage of undernutrition and short stature. Using the same anthropometric measurements IAC did not present overlapping diagnoses and detected more undernutrition. P/E is useful as screening, but insufficient in chronic undernutrition.

Population profiles associated with severe functioning difficulties and disability among two to four years old children in Mexico / Perfiles poblacionales asociados a dificultades severas de funcionamiento y discapacidad en niños de dos a cuatro años de edad en México

Abstract: Objective: To describe the prevalence and factors associated with severe child functioning difficulties and disability (CFD) among two to four year old children in Mexico, and estimates the probability of presenting CFD based on specific population profiles. Materials and methods: The sample consists of 5 104 children who participated in the National Survey of Children and Women 2015 (ENIM). We used post-estimation exploration by computing predicted values of CFD to interpret the logistic models for discrete combinations of the independent variables. Results: CFD prevalence is 2%, which means at least 130 000 two to four year-old children are at risk of experiencing severely limited participation in an unaccommodating environment. The probability of presenting CFD is dramatically higher in specific sub-groups of the population, in particular, male children of women with low education, who live in the poorest households. Conclusions: A significant proportion of Mexican children face important challenges due to functioning difficulties and disability. Public policies must be developed to accommodate the needs of these children and provide a proper environment for their development.

Resumen: Objetivo: Describir la prevalencia y los factores asociados con las dificultades severas de funcionamiento y discapacidad (CFD, por sus siglas en inglés) en niños de dos a cuatro años de edad en México y estimar la probabilidad de presentar CFD basada en perfiles poblacionales específicos. Material y métodos: La muestra fue conformada por 5 104 niños participantes de la Encuesta Nacional de los Niños, Niñas y Mujeres (ENIM) 2015. Se realizó una post-estimación calculando los valores predichos de CFD para interpretar los modelos logísticos a partir de combinaciones discretas de las variables independientes. Resultados: La prevalencia de CFD es de 2%, lo que significa que al menos 130 000 niños de 2 a 4 años de edad están en riesgo de experimentar una participación severamente limitada en un ambiente no adaptado a sus necesidades. La probabilidad de presentar CFD aumenta dramáticamente en subgrupos específicos de la población, en particular los hijos varones de mujeres con baja educación, que viven en los hogares más pobres. Conclusión: Una proporción importante de la población infantil mexicana enfrenta retos importantes derivados de las dificultades de funcionamiento y la discapacidad. Es necesario desarrollar políticas públicas que respondan a las necesidades específicas de este grupo poblacional, proporcionando un entorno apropiado para su desarrollo.

Population profiles associated with severe functional difficulties and disability among 5-17 years-old children in México / Perfiles poblacionales asociados con dificultades funcionales y discapacidad severa en niños de 5-17 años en México

Abstract: Objectives: To report the prevalence of severe functional difficulties and disability (SFD) in a nationally representative sample of children ages 5 to 17 in Mexico, to identify factors associated with SFD, and population profiles predictive of SFD. Materials and methods: Using data from the National Survey on Children and Women we estimated prevalence and 95% confidence intervals of SFD and risk factors. We fitted bivariate and multivariate logistic regression models. We then examined which combinations of the sociodemographic factors best predicted SFD. Results: The prevalence of SFD was 11.2%. The most prevalent SFD were on the socioemotional dimension (8.3%). The associated risk factors in the three dimensions were: living in a poor household, being a boy, having a mother with basic education or less, and non-indigenous background or living in an urban area. Conclusions: Identifying groups of the population at higher risk for SFD provides useful information for targeted intervention implementation.

Resumen: Objetivos: Reportar la prevalencia de dificultades funcionales y discapacidad severa (SFD) en una muestra nacional representativa de niños de 5 a 17 años en México; identificar los factores asociados con SFD; documentar los perfiles poblacionales que predicen SFD. Material y métodos: Se utilizaron los datos de la Encuesta Nacional de Niñas, Niños y Mujeres en México; se estimaron prevalencias e intervalos de confianza al 95%. Se ajustaron modelos bivariados y multivariados. Se examinaron las combinaciones de factores sociodemográficos que mejor predecían la SFD. Resultados: La prevalencia de SFD fue de 11.2%. Las SFD más prevalentes fueron en la dimensión socioemocional (8.3%). Los factores de riesgo asociados en las tres dimensiones fueron pobreza, ser hombre, tener una madre con educación primaria o menor, no ser indígena o vivir en zonas urbanas. Conclusiones: Identificar a los grupos con mayor riesgo de SFD dentro de la población proporciona información útil para el desarrollo de intervenciones.

Nutrition situation in Latin America and the Caribbean: current scenario, past trends, and data gaps / Situación nutricional en América Latina y el Caribe: panorama actual, tendencias y brechas en la información

ABSTRACT Objective To determine the current nutritional status in Latin America and the Caribbean (LAC) and identify data gaps and trends in nutrition surveillance. Methods A systematic Internet search was conducted to identify official sources that allowed for monitoring of LAC countries’ nutritional status, including progress toward World Health Organization Global Nutrition Targets 2025. Reports from national nutrition surveillance systems and reports on nationally representative surveys were collected and collated to 1) analyze nutritional status, based on life-course anthropometric indicators and biomarkers, and 2) identify gaps in data availability and trends in nutritional deficiencies. Information on iron, vitamin A, iodine, folate, and vitamin B12 deficiency was also collected and collated. Results Twenty-two of the 46 LAC countries/territories (48%) had information on undernutrition (stunting, underweight, and wasting) in children under 5 years old and women of reproductive age (WRA). Seventeen countries (38%) had information on anemia in children under 5 years old and WRA, and 12 (27%) had information on anemia in pregnant women. Although overall nutritional status has improved in the past few decades in all countries in the region, some LAC countries still had a high prevalence of stunting and anemia in children and WRA. Overweight affected at least 50% of WRA in nine countries with available data, and was increasing in children. Data for school-age children, adolescents, adult males, and older adults were scarce in the region. Conclusions Overall nutritional status has improved in the LAC countries with available information, but more efforts are needed to scale up nutrition-sensitive and nutrition-specific interventions to tackle malnutrition in all its forms, as stunting, anemia, and vitamin A deficiency are still a public health problem in many countries, and overweight is an epidemic. Nutrition information systems are weak in the region, and countries need to strengthen their capacity to monitor nutritional status indicators.

RESUMEN Objetivo Determinar la situación actual de las carencias nutricionales en América Latina y el Caribe (ALC) e identificar las deficiencias en los datos y el curso actual de la vigilancia en materia de nutrición. Métodos Se realizó una búsqueda sistemática de la internet para encontrar fuentes oficiales dedicadas a observar la evolución de la situación nutricional de los países de América Latina y el Caribe, incluidos los avances en relación con las metas mundiales de nutrición fijadas por la Asamblea Mundial de la Salud para el 2025. Se recopilaron y compaginaron los informes de diferentes sistemas de vigilancia nutricional nacionales y de encuestas representativas de alcance nacional con el fin de: (1) analizar la situación nutricional con respecto a indicadores antropométricos y marcadores biológicos para todas las etapas de la vida y (2) detectar brechas en la disponibilidad de datos y observar la evolución de las carencias nutricionales. También se recopiló y compaginó información relativa a la carencia de hierro, vitamina A, yodo, folato y vitamina B12. Resultados Veintidós países de América Latina y el Caribe (48%) contaban con información acerca de la desnutrición (retraso del crecimiento, peso inferior al normal y emaciación) en niños menores de 5 años de edad, niños en edad escolar, adolescentes y mujeres en edad fecunda (MEF). Diecisiete países (38%) tenían información sobre la anemia en niños menores de 5 años; 12 (27%) la tenían sobre la anemia en MEF. Aunque la situación nutricional en general ha mejorado en los últimos decenios en todos los países de la Región, algunos países de América Latina y el Caribe siguen teniendo una alta prevalencia de retraso del crecimiento y anemia en niños y MEF. El sobrepeso afectaba a por lo menos 50% de las MEF en nueve de los países que poseían datos y estaba aumentando en los niños. En la Región hay pocos datos relativos a los niños en edad escolar, los adolescentes, los hombres adultos y las personas de edad. Conclusiones La situación nutricional en general ha mejorado en los países de América Latina y el Caribe para los cuales se cuenta con información, pero hay que tomar más medidas para incrementar las intervenciones relacionadas de manera tangencial o directa con la nutrición a fin de combatir la desnutrición en todas sus manifestaciones, habida cuenta de que el retraso del crecimiento, la anemia y la carencia de vitamina A siguen siendo problemas de salud pública en muchos países y que el sobrepeso constituye una epidemia. Los sistemas de información nutricional de la Región son pobres y los países tienen que fortalecer su capacidad para vigilar los indicadores de la situación nutricional.

Stunting in children under five years old is still a health problem in the Western Brazilian Amazon: a population-based study in Assis Brasil, Acre, Brazil / Nanismo em crianças menores de cinco anos de idade ainda é um problema de saúde na Amazônia Ocidental Brasileira: um estudo de base populacional em Assis Brasil, Acre, Brasil

Abstract Despite the process of nutritional transition in Brazil, in some places, such as the Amazon region, stunting is still an important public health problem. We identified the prevalence and factors associated with stunting in children under five years old residing in the urban area of Assis Brasil. A survey was conducted in which a questionnaire on socioeconomic, maternal and children’s conditions was applied, and height or length was measured. The children with height for age index below -2 Z-scores were considered stunted, according to the criteria by the World Health Organization. Four hundred and twenty-eight children were evaluated. Of these, 62 were stunted. Factors associated with stunting, according to adjusted models, were: the presence of open sewer, the wealth index for households, the receipt of governmental financial aid and the mother’s height, age and education. Therefore, it was observed that family and the mother’s characteristics as well as environmental and socioeconomic factors were closely related to the occurrence of stunting in the population studied, and such nutritional disturbance is still a health problem in the Brazilian Amazon.

Resumo Apesar do processo de transição nutricional no Brasil, em alguns lugares, como a região amazônica, o nanismo ainda é um importante problema de saúde pública. Identificou-se a prevalência e fatores associados ao déficit de crescimento em crianças menores de cinco anos de idade residentes na área urbana de Assis Brasil. Um inquérito foi realizado utilizando instrumento semiestruturado sobre características socioeconômicas, maternas e das crianças, e foram aferidas medidas antropométricas. As crianças com índice de estatura para idade inferior a -2 escores-Z foram consideradas com déficit de crescimento, de acordo com os critérios da Organização Mundial da Saúde. Quatrocentos e vinte e oito crianças foram avaliadas. Destas, 62 apresentaram déficit de crescimento. Os fatores associados à baixa estatura, de acordo com modelos ajustados, foram: presença de esgoto a céu aberto, índice de riqueza para as famílias, recebimento de ajuda financeira governamental, altura materna, idade e escolaridade maternas. Portanto, observou-se que as características familiares e da mãe, bem como fatores ambientais e socioeconômicos estavam intimamente relacionados com a ocorrência de déficit de crescimento na população estudada, e que a desnutrição ainda é um problema de saúde na Amazônia brasileira.

Prevalence of stunting and overweight/obesity among Brazilian children according to different epidemiological scenarios: systematic review and meta-analysis / Prevalências de déficit de estatura e de sobrepeso/obesidade em crianças brasileiras, segundo diferentes cenários epidemiológicos: revisão sistemática com metanálise

ABSTRACT: CONTEXT AND OBJECTIVE: Within the Brazilian nutritional panorama, coexistence of antagonistic nutritional disorders can be seen, especially the increasing prevalence of overweight and the persistence of significant rates of chronic malnutrition in vulnerable groups of the population. Because these are major public health problems, this study aimed to ascertain the prevalence of stunting and overweight/obesity among Brazilian children according to different epidemiological scenarios. DESIGN AND SETTING: This was a systematic review of prevalence studies, developed at the State University of Paraíba. METHODS: The SciELO, Lilacs and PubMed databases were searched for articles, using specific keywords. Articles published between 2006 and 2014 were selected. The review was conducted by two reviewers who worked independently. A systematic review with meta-analysis was conducted, for which the studies were grouped within different epidemiological settings. RESULTS: Among the 33 articles recovered, 9 involved samples from daycare centers, 4 had samples from public healthcare services or social registers, 5 related to populations in situations of social inequity and 15 were population-based. Higher chances of stunting were found in populations in situations of social inequity and in those at public healthcare services or on social registers, in relation to reference populations. For overweight/obesity, none of the scenarios had a higher chance than the reference. CONCLUSION: Among Brazilian children, stunting continues to be a socially determined public health problem that mainly affects marginalized populations. This problem coexists with significant rates of overweight/obesity affecting all social groups.

RESUMO: CONTEXTO E OBJETIVO: O panorama nutricional brasileiro revela a coexistência de agravos nutricionais antagônicos, com destaque para as prevalências crescentes de excesso de peso e a persistência de taxas expressivas de desnutrição crônica em grupos vulneráveis da população. Por constituírem importantes problemas de saúde pública, este artigo teve por objetivo verificar as prevalências de déficit de estatura e de sobrepeso/obesidade em crianças brasileiras segundo diferentes cenários epidemiológicos. TIPO DE ESTUDO E LOCAL: Revisão sistemática de estudos de prevalência, desenvolvida na Universidade Estadual da Paraíba. MÉTODOS: Os artigos foram pesquisados nos bancos de dados SciELO, Lilacs e PubMed, usando-se palavras-chave específicas. Selecionaram-se artigos publicados entre 2006 e 2014. A revisão foi conduzida por dois revisores de forma independente. Realizou-se revisão sistemática com metanálise, para a qual os estudos foram agrupados em diferentes cenários epidemiológicos. RESULTADOS: Dentre os 33 artigos recuperados, 9 envolveram amostras obtidas em creches, 4 de serviços públicos de saúde ou de cadastros sociais, 5 foram referentes a populações com iniquidades sociais e 15 tinham base populacional. Maiores chances de déficit de estatura foram constatadas nas populações com iniquidade social e naquelas provenientes de serviços públicos de saúde ou de cadastros sociais, em relação às populações de referência. Para o sobrepeso/obesidade, nenhum cenário apresentou maior risco do que a referência. CONCLUSÕES: Nas crianças brasileiras, o déficit de estatura continua representando um problema de saúde pública de determinação social que atinge, principalmente, populações marginalizadas. Essa problemática coexiste com taxas expressivas de sobrepeso/obesidade que afetam todos os grupos sociais.
