Trend and correlation of obesity and continued breastfeeding in children from six to 3 months old / Tendência e correlação de obesidade e aleitamento materno continuado em crianças de seis a 23 meses

Abstract Objectives: to analyze the trend and correlation of obesity and the increase in continued breastfeeding in children aged six to 23 months in Brazil, from 2015-2019. Methods: ecological time series study with data from the Sistema de Vigilância Alimentar e Nutricional (Food and Nutritional Surveillance System). The dependent variable was the prevalence of obesity. Prais-Winsten linear regression was used to verify the trend. Spearman's correlation was used to verify the relationship between the prevalence of obesity and the increase in continued breastfeeding. Results: there was a trend towards a reduction in the prevalence of obesity in all regions in Brazil (Annual Percentage Variation [APV]: -4.14; CI95%=-4.50; -3.79). The prevalence of continued breastfeeding showed an upward trend in the North (APV=4.89; CI95%=2.92; 6.90), Southeast (APV=3.36; CI95%=2.32; 4 .41) and South (APV=2.67; CI95%=0.98; 4.38). There was a negative and significant correlation between obesity and continued breastfeeding in the North, Northeast, Southeast and South regions. Conclusion: the reduction in the prevalence of obesity and the increase in continued breastfeeding occurred only in some regions, requiring the implementation of effective strategies to be present throughout the country. Actions to promote, protect and support continued breastfeeding and healthy eating should be more prioritized to promote the child's healthy growth.

Conclusão: a redução da prevalência da obesidade e o aumento do aleitamento materno continuado ocorreram somente em algumas regiões, requerendo implementação de estratégias eficazes para esteja presente em todo o país. Ações de promoção, proteção e apoio ao aleitamento materno continuado e a alimentação saudável devem ser mais priorizadas para promover o crescimento saudável da criança.

Determinantes socioeconómicos del exceso de peso en niños preescolares y escolares colombianos. Encuesta Nacional de Situación Nutricional 2015 / Socioeconomic determinants of excess weight in Colombian preschool and school children. National Survey of Nutritional Situation 2015

Introducción: El exceso de peso infantil es un problema de salud pública, muestra una tendencia creciente, lo que repercutirá en el estado de salud y calidad de vida de los futuros adultos; se hace necesario mejorar la comprensión de los determinantes socioeconómicos de este fenómeno. Objetivo: Analizar los principales determinantes socioeconómicos intermedios y estructurales que influyen en el exceso de peso en niños en edad preescolar (3-5 años) y escolar (6-12 años) en Colombia. Materiales y métodos: Diseño descriptivo correlacional transversal con datos de la Encuesta Nacional de Situación Nutricional 2015 (ENSIN). Se realizaron modelos logísticos para explicar el exceso de peso (variable dependiente) en preescolares (puntaje Z del peso para la talla >+2DE) y escolares (IMC para la edad >+1DE). Resultados: Los niños preescolares que no consumen onces o media tarde tienen 60% menos riesgo de exceso de peso en comparación con los que si consumen. Los niños escolares tienen mayor riesgo de exceso de peso, a mayor índice de riqueza de la familia (2,09 veces), al pasar mucho tiempo frente a una pantalla (1,4 veces), al no realizar actividad física, y al estar en una familia con 2 hasta 5 integrantes. Conclusiones: Existen diferentes determinantes intermedios y estructurales para la población preescolar y escolar colombiana que influyen en el exceso de peso. Se recomienda profundizar en las políticas públicas de salud para educar y prevenir sobre alteraciones nutricionales y complicaciones a largo plazo que vayan en detrimento de la calidad de vida de los ciudadanos(AU)

Introduction: Childhood excess weight is a public health problem, it shows a growing trend, which will affect the health status and quality of life of future adults; It is necessary to improve the understanding of the socioeconomic determinants in this phenomenon. Objective: To analyze the main intermediate and structural socioeconomic determinants that influence excess weight in children of preschool age (3-5 years) and school age (6-12 years) in Colombia. Materials and methods: Cross-sectional correlational descriptive design with data from the 2015 National Nutritional Situation Survey (ENSIN). Logistic models were performed to explain excess weight (dependent variable) in preschool children (weightfor- height Z-score >+2SD) and schoolchildren (BMI-forage >+1SD). Results: Preschool children who do not consume elevenses or mid-afternoon have 60% less risk of excess weight compared to those who do consume. Schoolchildren have a higher risk of being overweight, the higher the family wealth index (2.09 times), the more time they spend in front of a screen (1.4 times), the less they do physical activity, and the more they are in a family with 2 to 5 members. Conclusions: There are different intermediate and structural determinants for the Colombian preschool and school population that influence excess weight. It is recommended to delve into public health policies to educate and prevent nutritional alterations and long-term complications that are detrimental to the quality of life of citizens.(AU)

Healthy lives, education and wealth: ecological relationships in social resilience

[EXTRACT]. A key feature of this special supplement of the Pan American Journal of Public Health is its focus on the state of chronic non-communicable diseases (NCDs) in the Caribbean. The negative value chain impact is its effects on economic growth and childhood educational outcomes. Thus, there is an ecological relationship between interventions to support dietary diversity, improving successful transitions from school to work and economic growth in the Caribbean Community (CARICOM). Since the 2007 Declaration of Port of Spain the region has made insufficient strides towards realizing the vision of reducing childhood obesity. In 2015, the Council for Trade and Economic Development (COTED) endorsed a 6-Point Policy Package (6-PPP) to promote healthy food environments and reduce the incidence of childhood obesity. The strategy supports the Caribbean Plan of Action to Prevent Childhood Obesity and the 6-PPP comprises mandatory food labelling, nutrition standards and guidelines for schools and other institutions, food marketing and portion sizes, nutritional quality of food supply (levels of harmful ingredients), trade and fiscal policies, and food chain incentives, particularly for fruits and vegetables.

Association between rapid weight gain and overweight in children aged 0 to 5 years in Latin America / Associação entre ganho rápido de peso e excesso de peso em crianças de 0 a 5 anos de idade na América Latina

Abstract Objectives: to assess the prevalence of rapid weight gain (RWG) in children born with normal weight and its association with overweight (OW) in four Latin America countries. Methods: cross-sectional study in children aged 0 to 5 from the Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher in Brazil and the Encuesta Nacional de Demografía y Salud in Bolivia, Colombia and Peru,using a birth weight ≥2,500g. The outcome variable was OW, the exposure was RWG and breastfeeding (BF) was the adjustment variable. Prevalence, odds ratio and 95% confidence intervalwere estimated using multivariate logistic regression model. Results: there was a greater prevalence of RWG and BF at less than 6 months in Brazil, and a greater prevalence of OW in Brazil and Bolivia. The chances of OW when RWG was present and adjusted for BF were 6.1 times (CI95% = 3.8-9.7) in Brazil, 4.4 times (CI95% = 3.6-5.3) in Bolivia, 6.7 times (CI95% = 5.5-8.2) in Colombia, and 12.2 times in Peru (CI95% = 9.4-15.7) with a p < 0.001 for all countries. Conclusions: RWG in children with normal birth weight was associated with a greater chance of being OW in the four observed Latin America countries.

Resumo Objetivos: avaliar a prevalência do ganho rápido de peso (GRP) em crianças nascidas com peso normal e sua associação com o excesso de peso (EP) em quatro países da América Latina. Métodos: estudo transversal de inquéritos populacionais com crianças de 0 a 5 anos da Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher no Brasil e da Encuesta Nacional de Demografía y Salud da Bolívia, Colômbia e Peru, selecionadas pelo peso ao nascer ≥2.500 gramas. A variável desfecho foi o EP; de exposição o GRP; e de ajuste a amamentação. Foram estimadas as prevalências, odds ratio e intervalo de confiança de 95% por regressão logística multivariada. Resultados: observou-se maior prevalência de GRP e tempo de amamentação menor do que 6 meses no Brasil e maior prevalência de EP no Brasil e Bolívia. As chances de EP quando GRP presente e ajustado por amamentação foram de 6,1 vezes (IC95% = 3,8-9,7) no Brasil; 4,4 vezes (IC95% = 3,6-5,3) na Bolívia; 6,7 vezes (IC95% = 5,5-8,2) na Colômbia; 12,2 vezes no Peru (IC95% = 9,4-15,7) e p<0,001 nos quatro países. Conclusões: o GRP em crianças nascidas com peso normal foi associado a maior chance de EP infantil nos quatro países da América Latina.

Percepção de gestores e profissionais de saúde sobre o cuidado da obesidade infanto-juvenil no Sistema Único de Saúde / Health managers and professionals' perception on the care of child and adolescent obesity in Brazil's Unified Health System

Resumo O estudo teve como objetivo analisar a percepção de gestores e profissionais de saúde sobre o cuidado disponível para crianças e adolescentes com sobrepeso e obesidade no Sistema Único de Saúde em Sergipe, Brasil. Trata-se de estudo qualitativo e exploratório, com amostra composta por 46 atores e coleta de dados por meio de entrevistas semiestruturadas. O cuidado existente foi percebido como falho e fragmentado, independentemente do nível de atenção à saúde. As principais dificuldades abrangeram o processo de trabalho, a gestão e organização do cuidado, a adesão familiar e a insuficiência de recursos. Potencialidades relacionadas à gestão, equipes e profissionais, que poderiam contribuir para a implantação de uma linha de cuidado integral, foram também identificadas. Contudo, a organização do cuidado à obesidade infantil ainda requer uma conectividade dos papéis e tarefas dos diversos atores, por meio da pactuação e corresponsabilização entre os serviços, profissionais e a família.

Abstract The study aimed to analyze the perception of health managers and professionals on the care of children and adolescents with overweight and obesity in the Unified Health System of Sergipe, Brazil. This is a qualitative and exploratory study with sample composed of 46 actors and semi-structured interviews as data collection method. The existing care was perceived as poor and fragmented, regardless of the health care level. The main difficulties were the professionals' work process, care management and organization, family support and insufficient resources. Potentialities related to management, teams and professionals, which could contribute to the implementation of a comprehensive care line, were also identified. However, the organization of care for child obesity still requires the connectivity of different actors' roles and tasks, with the agreement and co-responsibility between services, professionals and family.

Os fatores de risco envolvidos na obesidade no adolescente: uma revisão integrativa / Risk factors involved in adolescent obesity: an integrative review

Resumo Os fatores de risco para o desenvolvimento da obesidade na adolescência constituem o objeto deste estudo. Por meio de uma revisão integrativa da literatura, buscou-se identificar os fatores de risco da obesidade nos adolescentes. Utilizou-se a estratégia PICO para se formular a seguinte pergunta norteadora: quais são os fatores de risco para o desenvolvimento da obesidade na adolescência? Os portais de pesquisa consultados foram: BVS e EBSCOhost, com o corpus do estudo ficando com 25 artigos. O fenômeno da obesidade foi entendido como resultante de fatores biológicos, sociais, psicológicos e nutricionais. Constatou-se que não existe um consenso sobre riscos e benefícios, o que dificulta recomendações de evidência. Foram identificadas, ainda, propostas passíveis de serem implementadas: a modificação de hábitos alimentares, o controle de peso e a prática de exercícios físicos. Tais modificações comportamentais podem ser recomendadas para os contextos familiares, escolares e dos serviços de saúde. A revisão recomenda estratégias de prevenção e pensar a escola como um espaço rico para promoção da saúde por intermédio da educação. Do ponto de vista político e social, é preciso enfrentar as propagandas da indústria alimentícia, que seduzem os adolescentes a consumirem alimentos processados e ricos em gordura e açúcar.

Abstract The scope of this study was to examine the risk factors for the development of obesity in adolescence. The objective was to identify risk factors for adolescent obesity by means of an Integrative Review of the Literature. The PICO strategy was used to formulate the following central line of inquiry: What are the risk factors for the development of obesity during adolescence? The VHL and EBSCOhost research databases were consulted, resulting in a selection of 25 articles for in-depth study. The phenomenon of obesity was understood as the result of biological, social, psychological, and nutritional factors. The research revealed a lack of consensus on the risks and benefits, which makes evidence-based recommendations difficult. The study identified proposals that can be implemented, such as a change in eating habits, weight control and the practice of physical exercise. Such behavioral changes can be recommended within the context of the family, schools, and health services. The review recommends prevention strategies and the recognition of school as the ideal medium for health promotion through education. From a political and social standpoint, it is necessary to challenge the prevalence of publicity of the food industry that entices adolescents to consume processed foods with high fat and sugar content.

Asociación del índice de masa corporal y relación cintura/estatura con la presión arterial como factor de riesgo metabólico en estudiantes universitarios / Body mass index and waist / height ratio association with blood pressure as a metabolic risk factor in college students

Los problemas relacionados con los trastornos metabólicos se han incrementado en la actualidad en población joven. Promover un estilo de vida saludable en estudiantes universitarios puede ayudar a prevenir diabetes, enfermedades cardiovasculares y diferentes tipos de cáncer. Objetivo. Calcular el Índice de Masa Corporal (IMC) de universitarios para identificar la prevalencia de obesidad e hipertensión como factores de riesgo metabólico. Materiales y método. Se utilizó muestreo probabilístico aleatorio simple (n= 282, edad 19,1 ± 1,8, 54,6% mujeres, 48,5% hombres). Se realizaron mediciones de peso y estatura para calcular el IMC, circunferencia de cintura y presión arterial. Resultados. Los resultados promedio para mujeres y hombres respectivamente fueron: IMC 24,0 ±5,5 y 25,2 ±5,2 kg/m2 (p= 0,25); cintura 76,25 ± 11,87 y 82,32 ± 15,85 cm (p= 0,001), indicando un riesgo bajo en 73,1% de mujeres y 82,5% de hombres; y presión arterial 127,73/86,03 y 142,3/94,2 mmHg (p= 0,001). La probabilidad de tener hipertensión arterial fue mayor al tener una relación cintura/estatura (RCE) alterada en mujeres y hombres (OR=3,037; IC95% 1,385-6,657 y OR=3,664; IC95% 1,249-2,179, respectivamente). Conclusiones. La población universitaria presenta factores de riesgo que pueden derivar en enfermedades crónicas no transmisibles en un futuro próximo, por lo cual es necesario modificar sus estilos de vida. La RCE es un buen predictor de riesgo de hipertensión en esta población(AU)

The problems related to metabolic disorders have now increased in the young population. Promoting a healthy lifestyle in college students can help prevent diabetes, cardiovascular disease, and different types of cancer. Objective. To calculate the Body Mass Index (BMI) in college students to identify the prevalence of obesity and hypertension as metabolic risk factors. Materials and methods. Simple random probability sampling was used (n = 282, age 19,1 ± 1,8, 54,6% women, 48,5% men). BMI was calculated with weight and height, waist circumference, and blood pressure. Results. The average results for women and men respectively were: BMI 24,0 ± 5,5 and 25,2 ± 5,2 kg/m2 (p = 0,25); waist 76,25 ± 11,87 and 82,32 ± 15,85 cm (p = 0,001), indicating a low risk in 73,1% of women and 82,5% of men; and blood pressure 127,73 / 86,03 and 142,3 / 94,2 mm Hg (p = 0,001). The probability of having arterial hypertension was higher when there was an altered waist / height ratio (WHR) in women and men (OR = 3,037; 95% CI 1,385-6,657 and OR = 3,664; 95% CI 1,249-2,179, respectively). Conclusions. The university population presents risk factors that could lead to chronic diseases. It is necessary to modify their lifestyles to prevent future diseases. WHR is a good predictor of hypertension risk in this population(AU)

Impact of nutritional and physical activity interventions on the cognitive and academic achievement of schoolchildren

The objective of this review is to present the impact of nutritional education, physical activity and support network interventions on the nutritional status, cognitive and academic achievement of students under 18 years of age. According to the literature, multicomponent interventions that address diet, physical activity, and involve parents concluded to be more effective in combating obesity and enhancing academic achievement in young people. Therefore, the implementation of public policies that commit to intervene in a timely manner in the first stages of the life cycle, would have a considerably beneficial impact on health(AU)

El objetivo de esta revisión es dar a conocer el impacto de las intervenciones de educación nutricional, actividad física y redes de apoyo en el estado nutricional, rendimiento cognitivo y académico de estudiantes menores de 18 años. De acuerdo con la literatura, las intervenciones de carácter multicomponente que abordan alimentación, actividad física, e involucran a los padres concluyeron ser más efectivas para combatir la obesidad y potenciar el rendimiento académico en jóvenes. Por lo tanto, la implementación de políticas públicas que permitan intervenir de forma oportuna las primeras etapas del ciclo vital, tendrían un impacto considerablemente beneficioso para la salud(AU)

Prevalencia de sobrepeso, obesidad con actividad física y nivel socioeconómico en escolares de educación básica / Prevalence of overweight, obesity with physical activity and socioeconomic status in elementary school students

INTRODUCCIÓN: el sobrepeso y obesidad infantil son problemas de salud pública en México, por lo que es necesario crear entornos que capaciten y motiven conductas positivas en relación a un estilo de vida saludable. OBJETIVOS: determinar la prevalencia de sobrepeso y obesidad. Describir la actividad física y sedentarismo con relación al nivel socioeconómico. MATERIAL Y MÉTODOS: se llevó a cabo un estudio descriptivo, observacional, transversal y prospectivo en 278 alumnos entre seis y 12 años de edad. Se calculó el IMC, se aplicaron cuatro cuestionarios: CVAFA, CCSNP, CNSE, AMAI 2018. RESULTADOS: la prevalencia de sobrepeso y obesidad fue de 42.7%. La actividad física vigorosa 49.6%. El 95% pasa dos horas diarias frente al televisor, 87% ocupa la computadora una hora diaria para tareas. El 32% toma siesta de 30 minutos. El nivel socioeconómico estuvo correlacionado a los primeros tres niveles. CONCLUSIONES: la prevalencia de sobrepeso y obesidad representa casi la mitad de la población estudiantil. La alimentación de tipo obesogénico da como resultado el IMC elevado, aunque el nivel socieconómico permitía obtener alimentos de buena calidad. La actividad física significativa sólo fue realizada por un bajo porcentaje de estudiantes. Las horas de descanso se encontraron adecuadas a su edad.

INTRODUCTION: Childhood overweight and obesity are public health problems in Mexico, so it is necessary to create environments that train and motivate positive behaviors in relation to a healthy lifestyle. OBJECTIVES: To determinate the prevalence of overweight and obesity. Describe physical activity and sedentary behaviors with socioeconomic status. MATERIAL AND METHODS: A descriptive, observational, cross-sectional and prospective study was carried out in 278 students between six and 12 years old. The BMI was calculated, four questionnaires were applied: CVAFA, CCSNP, CNSE, AMAI 2018. RESULTS: the prevalence of overweight and obesity was 42.7%. Vigorous physical activity 49.6%. A 95% spend two hours a day in front of the television, 87% use the computer an hour a day for homework. 32% nap for 30 minutes. The economic level is correlated to the first three levels. CONCLUSIONS: the prevalence of overweight and obesity represents almost half of the student population. The obesogenic type diet results in a high BMI, although the economic level allowed obtaining quality food. Significant physical activity was also performed by a low percentage of students. The hours of rest were found to be appropriate for their age.

Variables sociofamiliares asociadas a mayor riesgo de sobrepeso y obesidad abdominal en niños escolares de un servicio de pediatría en Colima, México / Socio-family variables associated with a higher risk of overweight and abdominal obesity in school children from a pediatric service at Colima, Mexico

Con el fin de identificar la asociación entre factores familiares (estructura, funcionalidad y contexto socioeconómico) y la presencia de sobrepeso y obesidad abdominal en escolares, se realizó un estudio transversal analítico en 120 niños escolares (5-11 años) y sus madres que acudieron a un servicio de atención pediátrica en la ciudad de Colima, México. El sobrepeso se definió con el indicador IMC con un puntaje Z > +1 desviación estándar y la obesidad abdominal como circunferencia de cintura > del percentil 75 por sexo y edad. Se evaluó tamaño y tipo de familia, tipo de hogar, relación de los padres y funcionalidad familiar. Las asociaciones se analizaron con regresión logística múltiple. Se encontró 33% de sobrepeso y 33,7% de obesidad abdominal. El menor tamaño de la familia, la mayor marginalidad de la colonia (barrio) de residencia, la percepción de problemas en la economía familiar, el mayor peso al nacer y la mayor edad se asociaron con el sobrepeso. Mientras que el menor tamaño de la familia, el mayor peso al nacer y la mayor edad se asociaron con obesidad abdominal. Para programas de prevención de sobrepeso y obesidad abdominal, sugerimos incluir un enfoque de sistemas familiares que considere el tamaño de la familia y variables del contexto socioeconómico, ya que condicionan su dinámica de interacción(AU)

To identify the association between family factors (structure, functionality, and socioeconomic context) and the presence of overweight and abdominal obesity in school children, an analytical cross-sectional study was performed in 120 schoolchildren (5-11 years old) and their mothers assisting to a pediatric care service at Colima City, Mexico. Overweight was defined with the BMI indicator with a Z-score > +1 standard deviation and abdominal obesity as a waist circumference > 75th percentile by sex and age. Family size and type, type of home, parents' relationship, and family functionality were evaluated. Associations were analyzed with multiple logistic regression. Overweight was present in 33%, and abdominal obesity in 33.7% of the children. A smaller family size, greater neighborhood marginality, a perception of problems in the family economy, a larger birth weight and older age were associated with overweight. A smaller family size, higher birth weight and older age were associated with abdominal obesity. We suggest a family systems approach, including family size and variables of socioeconomic context -which determine their interaction dynamics-, in programs for overweight and abdominal obesity prevention(AU)

La falacia de los niños gordos anémicos / The fallacy of the fat anemic child

Fundamento: los estudios sugieren la presencia de deficiencia de hierro en niños obesos, lo que conduciría a una mayor incidencia de anemia en este grupo. Objetivo: evaluar la prevalencia de anemia entre niños con sobrepeso y obesidad de dos niveles socioeconómicos y dos regiones diferentes en Brasil. Métodos: se obtuvieron datos de hemoglobina y antropometría de 598 niños y adolescentes con sobrepeso y obesidad de dos servicios especializados en la atención de estos niños. Resultados: la prevalencia global de anemia fue del 5,8% y el nivel medio de hemoglobina fue de 13,2 mg / dL, sin diferencia estadística para los dos indicadores según sobrepeso u obesidad y grupo de edad. Sin embargo, la hemoglobina media fue mayor entre los varones y, en el servicio con atención prestada a una población de menor nivel socioeconómico, la prevalencia de anemia fue mayor. Conclusión: la prevalencia de anemia encontrada en niños y adolescentes con sobrepeso y obesidad fue bastante baja, siendo mayor en la población más pobre. Para los niños y adolescentes con sobrepeso, la anemia parece estar más relacionada con el nivel socioeconómico que con la presencia de exceso de peso.

Background: studies suggest the presence of iron deficiency among obese children, which would lead to a higher incidence of anemia in this group. Aim: to assess the prevalence of anemia among overweight and obese children from two socioeconomic levels and two different regions in Brazil. Methods: hemoglobin and anthropometric data on 598 overweight and obese children and adolescents were obtained from two services specialized in the care of these children. Results: the overall prevalence of anemia was 5.8% and mean hemoglobin level was 13.2 mg/dL, with no statistical difference for the two indicators according to overweight or obesity and age group. However, the mean hemoglobin was higher among boys and, in the service with care provided to a population of lower socioeconomic status, the prevalence of anemia was higher. Conclusion: the prevalence of anemia found among overweight and obese children and adolescents was quite low, being higher in the poorest population. For overweight children and adolescents, anemia seems to be more related to socioeconomic status than to the presence of excess weight.

Impacto de una intervención de educación prenatal en mujeres embarazadas para prevenir el sobrepeso en lactantes / Impact of a prenatal education intervention in pregnant women to prevent overweight in infants

Resumen Introducción: Durante los primeros 1000 días de vida se establece la base para la salud futura de un niño. Objetivo: Evaluar el impacto de una intervención educativa prenatal en mujeres embarazadas sobre el estado nutricional del hijo desde el nacimiento hasta los cuatro meses de edad. Métodos: Diseño cuasiexperimental de intervención con mujeres a partir de la semana 12 de gestación, asignadas aleatoriamente a un grupo de intervención (GI) para recibir cinco sesiones grupales y tres individuales sobre prácticas de alimentación y percepción materna del peso del hijo y de señales de hambre-saciedad; el grupo control (GC) recibió atención de rutina que incluía al menos tres consultas prenatales. Resultados: 30 mujeres conformaron cada grupo. Después de la intervención, las mujeres del GC practicaron menos lactancia materna exclusiva, fueron propensas a subestimar o sobrestimar el peso del hijo y percibieron con menor intensidad las señales de hambre-saciedad (p < 0.05). El 80 % de los lactantes del GI presentaron peso normal y 63 % de los niños del GC, una combinación de sobrepeso y obesidad (p < 0.05). Conclusiones: El programa de educación prenatal en mujeres embarazadas mostró un efecto significativo en el estado nutricional de los lactantes después de cuatro meses del nacimiento.

Abstract Introduction: During the first 1000 days of life is the basis for a child's future health established. Objective: To evaluate the impact of a prenatal educational intervention in pregnant women on the nutritional status of the child from birth to 4 months of age. Methods: Quasi-experimental intervention design in women with at least 12 weeks of gestation, who were randomly assigned to an intervention group (IG) to participate in five group and three individual sessions on feeding practices and maternal perception of the child's weight and signals of hunger-satiety; the control group (CG) received routine care that included at least three prenatal consultations. Results: Thirty women were included in each group. After the intervention, women in the CG practiced less exclusive breastfeeding, were more likely to underestimate and overestimate the children's weight, and perceived hunger-satiety signals with less intensity (p < 0.05). 80 % of the infants in the IG had normal weight, whereas 63 % of those in the CG had a combination of overweight and obesity (p < 0.05). Conclusions: The prenatal education program in pregnant women showed a significant effect on postnatal nutritional status of infants four months after birth.

Una nueva mirada a los determinantes del peso infantil en la primera infancia / A new examination of the determinants of weight in early childhood

INTRODUCCIÓN: En las últimas décadas, Chile ha experimentado una triple transición demográfica, nutricional y eco nómica. OBJETIVO: Explorar la relación entre peso infantil y dos aspectos del nivel socioeconómico, ingreso familiar y educación materna, estudiando el efecto de cada uno por si solo y la manera en que operan juntos para determinar el peso infantil y comparar su efecto en menores obesos y en otro estatus de peso. SUJETOS Y MÉTODO: Estudio de fuentes secundarias de datos obtenidos de la En cuesta Longitudinal de Primera Infancia de 2012, analizando niños y niñas entre 2 y 6 años de edad (n = 11.339). Se estimaron modelos multivariados de regresión cuantílica para el puntaje z del índice de masa corporal (zIMC). RESULTADOS: En niños, entre 2 y 3 años, el ingreso y peso infantil tuvieron una asociación positiva, mientras que educación materna y peso infantil una negativa. Entre los 4 y 6 años, ingreso y peso infantil tuvieron una asociación negativa entre hijos de madres con estudios superiores, pero positiva entre hijos de madres con más baja educación. CONCLUSIÓN: Ingreso familiar y educación materna tienen efectos opuestos en el peso infantil. El efecto positivo de ingreso sobre zIMC es mitigado en casos de madres con altos logros educativos. Recomendamos estudiar el efecto de ingreso y educación en el peso infantil por separado e investigar los mecanismos causales que ex plican la relación entre determinantes socioeconómicos y peso infantil.

INTRODUCTION: In the last decades, Chile has experienced a triple transition regarding demographic, nutritional, and economic issues. OBJECTIVE: To explore the relationship between childhood weight and two dimen sions of socioeconomic status, family income, and maternal educational level, analyzing the effect of each one by itself and how they operate together to determine childhood weight and comparing their effect on obese and non-obese children. SUBJECTS AND METHOD: Study based on data from the 2012 Encuesta Longitudinal de Primera Infancia (Early Childhood Longitudinal Survey), evaluating children between 2 and 6 years old (n=11,399). We estimated multivariate quantile regression models for the z-score of the body mass index (BMI-z). RESULTS: We found that in children aged 2-3 years, income and weight had a positive association, while maternal educational level and weight had a negative one. In children aged 4-6 years, income and weight were negatively associated among chil dren whose mothers have a higher educational level but positive among those with lower educational levels. CONCLUSION: Family income and maternal educational level have opposite effects on childhood weight. The positive effect of income on BMI-z is diminished when mothers have high educational levels. We recommend studying the effects of income and education on child weight separately and exploring the causal mechanisms that explain the relations between socioeconomic determinants and childhood weight.

COVID-19 and obesity in childhood and adolescence: a clinical review / COVID-19 e obesidade na infância e adolescência: uma revisão clínica

Abstract Objective: To identify factors that contribute to the increased susceptibility and severity of COVID-19 in obese children and adolescents, and its health consequences. Sources: Studies published between 2000 and 2020 in the PubMed, MEDLINE, Scopus, SciELO, and Cochrane databases. Summary of findings: Obesity is a highly prevalent comorbidity in severe cases of COVID-19 in children and adolescents; social isolation may lead to increase fat accumulation. Excessive adipose tissue, deficit in lean mass, insulin resistance, dyslipidemia, hypertension, high levels of proinflammatory cytokines, and low intake of essential nutrients are factors that compromise the functioning of organs and systems in obese individuals. These factors are associated with damage to immune, cardiovascular, respiratory, and urinary systems, along with modification of the intestinal microbiota (dysbiosis). In severe acute respiratory syndrome coronavirus 2 infection, these organic changes from obesity may increase the need for ventilatory assistance, risk of thromboembolism, reduced glomerular filtration rate, changes in the innate and adaptive immune response, and perpetuation of the chronic inflammatory response. Conclusions: The need for social isolation can have the effect of causing or worsening obesity and its comorbidities, and pediatricians need to be aware of this issue. Facing children with suspected or confirmed COVID-19, health professionals should 1) diagnose excess weight; 2) advise on health care in times of isolation; 3) screen for comorbidities, ensuring that treatment is not interrupted; 4) measure levels of immunonutrients; 5) guide the family in understanding the specifics of the situation; and 6) refer to units qualified to care for obese children and adolescents when necessary.

Resumo Objetivo: Identificar fatores que contribuem para o aumento da suscetibilidade e gravidade da COVID-19 em crianças e adolescentes obesos e suas consequências para a saúde. Fontes de dados: Estudos publicados entre 2000 e 2020 nas bases de dados PubMed, Medline, Scopus, SciELO e Cochrane. Síntese dos dados: A obesidade é uma comorbidade altamente prevalente em casos graves de COVID-19 em crianças e adolescentes e o isolamento social pode levar ao aumento do acúmulo de gordura. Tecido adiposo excessivo, déficit de massa magra, resistência à insulina, dislipidemia, hipertensão, altos níveis de citocinas pró-inflamatórias e baixa ingestão de nutrientes essenciais são fatores que comprometem o funcionamento dos órgãos e sistemas no indivíduo obeso. Esses fatores estão associados a danos nos sistemas imunológico, cardiovascular, respiratório e urinário, juntamente com a modificação da microbiota intestinal (disbiose). Na infecção por SARS-CoV-2, essas alterações orgânicas causadas pela obesidade podem aumentar a necessidade de assistência ventilatória, risco de tromboembolismo, taxa de filtração glomerular reduzida, alterações na resposta imune inata e adaptativa e perpetuação da resposta inflamatória crônica. Conclusões: A necessidade de isolamento social pode ter o efeito de causar ou agravar a obesidade e suas comorbidades e pediatras precisam estar cientes desse problema. Diante de crianças com suspeita ou confirmação de COVID-19, os profissionais de saúde devem 1) diagnosticar o excesso de peso; 2) aconselhar sobre cuidados de saúde em tempos de isolamento; 3) fazer a triagem de comorbidades, garantindo que o tratamento não seja interrompido; 4) medir os níveis de imunonutrientes; 5) orientar a família respeitando as especificidades da situação; e 6) encaminhamento a unidades qualificadas para cuidar de crianças e adolescentes obesos, quando necessário.

Obesidade na infância e adolescência / Obesity in childhood and adolescence

A obesidade é uma doença crônica e multifatorial com sérias repercussões na saúde. O excesso de peso na infância aumenta o risco de obesidade na adolescência e na vida adulta. A obesidade é uma das principais causas de hipertensão arterial em crianças e adolescentes. No sexo feminino, os problemas ginecológicos relacionados com a obesidade incluem as desordens menstruais e a diminuição da fertilidade na adolescência e na vida adulta. O controle dessa patologia evita a sua evolução para formas crônicas e graves, que acarretaria novos transtornos e consequências para essas jovens. A mudança de hábitos alimentares e a realização de atividade física são a principal linha de tratamento. O tratamento medicamentoso é reservado para portadoras de obesidade grave que apresentam comorbidades associadas e que não respondem às mudanças do estilo de vida. (AU)

Obesity is a chronic and multifactorial disease with serious repercussions on health. Overweight in childhood increases the risk of obesity in adolescence and adulthood. Obesity is one of the main causes of high blood pressure in children and adolescents, among others. In women, gynecological problems related to obesity include menstrual disorders and decreased fertility in adolescence and adulthood. The control of this pathology prevents its evolution to chronic and severe forms that would cause new disorders and consequences for these young women. The main line of treatment is to change eating habits and encourage physical activity. Drug treatment is reserved for patients with severe obesity, who have associated comorbidities and who do not respond to changes in lifestyle.(AU)

Serum ferritin levels among schoolchildren and its correlation with lipid profile and adiposity

To determine the association between serum ferritin levels, lipid profile and adiposity in school-age children. Methods: A cross-sectional study was conducted on obese and non-obese children. Weight, height, waist circumference and blood pressure were measured for all participants. Lipid profile, serum ferritin and glucose were determined and analysed through absorbance. The Spearman correlation was performed for the quantitative variables and a regression analysis was used to determine the interaction between variables. Eighty-nine children were included, with a median age of 9.0 years. Results: When comparing serum ferritin levels in normal weight group, vs. the overweight and obesity group, values were significantly higher in the latter. Serum ferritin correlated positively with BMI (Rho .282, p <0.01), waist circumference (Rho .372, p < 0.01), diastolic blood pressure (Rho .244, p < 0.05), body fat percentage (Rho .375, p < 0.001), insulin (Rho .254, p <.05) and sex (Rho .224, p <.05); and negatively with high-density lipoprotein cholesterol (Rho. -221, p< 0.05). When analysing the significant variables in a multivariate regression model, sex, body mass index, waist circumference, and body fat percentage remained statistically significant (p <0.01). Conclusion: We observed associations between serum ferritin and obesity in Mexican school aged children(AU)

Determinar la asociación entre los niveles de ferritina sérica, el perfil de lípidos y la adiposidad en niños en edad escolar. Metodología: Se realizó un estudio transversal en niños obesos y no obesos. Se midieron el peso, la altura, la circunferencia de cintura y la presión arterial en todos los participantes. El perfil lipídico, la ferritina sérica y la glucosa se determinaron y analizaron mediante absorbancia. Se realizó correlación de Spearman para las variables cuantitativas y se utilizó un análisis de regresión para determinar la interacción entre las variables. Se incluyeron ochenta y nueve niños, con una edad media de 9,0 años. Resultados: Al comparar los niveles de ferritina sérica en el grupo de peso normal, frente al grupo de sobrepeso y obesidad, los valores fueron significativamente más altos en este último. La ferritina sérica se correlacionó positivamente con el IMC (Rho 0,282, p <0,01), la circunferencia de cintura (Rho 0,372, p <0,01), la presión arterial diastólica (Rho 0,244, p <0,05), el porcentaje de grasa corporal (Rho 0,375, p < 0,001), insulina (Rho 0,254, p <0,05) y sexo (Rho 0,224, p < 0,05); y negativamente con colesterol de lipoproteínas de alta densidad (Rho -0,221, p <0,05). Al analizar las variables significativas en un modelo de regresión multivariante, el sexo, el índice de masa corporal, la circunferencia de cintura y el porcentaje de grasa corporal se mantuvieron estadísticamente significativos (p <0,01). Conclusión: Observamos asociaciones entre la ferritina sérica y la obesidad en niños mexicanos en edad escolar(AU)

Análise do marketing dos produtos alimentícios infantís / Marketing analysis of children's food products

Objetivo ­ Analisar o marketing nos produtos alimentícios destinados ao público infantil. Métodos ­ O método de abordagem utilizado foi de observação, hipotético dedutivo, de forma quantitativa, dos produtos voltados para o público infantil, comercializados em hipermercados (representados por Y¹ e Y²), em mercado de bairro (representados por X¹ e X²) e atacadistas (representados por Z¹ e Z²), no município de Taubaté/SP. Cada produto analisado foi classificado em sete categorias. Resultados ­ Foi feita a observação de 432 produtos que possuem em seus rótulos personagens ou desenhos infantis, sendo 419 produtos industrializados e 13 produtos naturais. Foram encontrados 30,09% de guloseimas; 27,54% de produtos lácteos; 15,5% de biscoito recheado; 14,81% salgadinho de milho; 9,02% de suco de fruta; 1,38% de frutas e 1,62% produtos integrais. Conclusão ­ Ao analisar quantos produtos naturais e industrializados fazem uso do mesmo personagem, não foi encontrado nenhum em comum. No momento da coleta dos dados foi possível observar que os produtos que possuem um marketing mais infantilizado estão dispostos em prateleiras mais baixas nos mercados de grande e médio porte, já nos mercados de pequeno porte estes produtos nem sempre estão em prateleiras baixas.
