Introducción: La deficiencia de hierro (DH) es considerada el problema nutricional más prevalente en todo el mundo. Similarmente el plomo es una sustancia tóxica ampliamente distribuida en la corteza terrestre, y en la actualidad todos los niños están expuestos al plomo. Ambas situaciones se presentan juntas en poblaciones infantiles desfavorecidas y afectan adversamente el desarrollo neurocognitivo de los niños. Objetivo: determinar si existe relación entre la DH y los niveles de plomo en sangre en niños de 1 a 6 años asistidos en el sistema público de salud de La Plata y Gran La Plata. Material y métodos: Se realizó un estudio analítico de corte transversal. Se evaluaron niños entre 1 y 6 años de edad, clínicamente sanos, que concurrieron por controles de salud periódicos al Observatorio de Salud del IDIP y a Centros de Atención Primaria de la Salud de La Plata y Gran La Plata, durante los años 2012-2017. Se realizó una evaluación antropométrica, se relevaron datos sociodemográficos y se determinaron el hemograma, la concentración de ferritina, y el nivel de plomo sanguíneo (NPS). Se consideró DH si ferritina 12 ng/ml, anemia si Hb < 11 gr/dL(o 11,5 gr/dL para los mayores de 5 años) y nivel elevado de plomo si NPS ≥ 5 µg/dL. Para el análisis estadístico se usó el paquete estadístico R versión 3.3.2. Se utilizaron las pruebas de Mann Whitney, o el Test de Student, Chi-cuadrado y regresión logística. Resultados: Participaron del estudio 394 niños, la edad promedio fue 2.4 ± 1.4 años. La prevalencia de DH fue 26,1 %, de anemia fue 31,6 %, la de NPS elevados fue de 8.6 %. El análisis bivariable mostró una asociación estadísticamente significativa entre la DH y la prevalencia de NPS ≥ 5 µg/dL con un OR (IC95%): 3,18 (1,52; 6,68). La prevalencia de NPS ≥ 5 µg/dL fue 16,2 % en niños con DH y de 5,7 % en los niños sin DH. (p=0,0027). También se halló asociación entre la anemia y la prevalencia de NPS mayor al valor de referencia OR (IC95%): 3,05 (1,50; 6,33). Conclusión: Se encontró asociación entre la DH y NPS mayor al valor de referencia, los niños con DH tienen el triple de chances de presentar NPS ≥5 µ/dL que los niños sin DH. Asimismo se encontró asociación entre la anemia y NPS mayor al valor de referencia CDC, los niños anémicos tienen el triple de chances de presentar NPS ≥5 µ/dL que los niños sin anemia, Facultad de Ciencias Médicas

INTRODUCCIÓN: las mujeres en período de lactancia y los lactantes son grupos vulnerables a la deficiencia de vitamina A (DVA). El objetivo del estudio fue determinar la relación entre el estado nutricional de vitamina A en la madre y el lactante alimentado con lactancia materna exclusiva. MÉTODOS: se realizó un estudio observacional analítico de corte transversal en lactantes de 6 meses y sus madres. Se determinó vitamina A en suero y leche por cromatografía líquida. Se calcularon concentraciones medias de vitamina A y prevalencias de DVA en suero y leche, y se compararon mediante tests estadísticos. RESULTADOS: se estudiaron 63 binomios madre-hijo. Las medias de retinol en suero materno y del lactante fueron 1,84±0,48 μmol/L y 1,09±0,25 μmol/L, respectivamente. No hubo madres con DVA, y el 5% de los lactantes estaban deficientes. La mediana de retinol en leche materna fue 15,57 μg/g grasa (11,37; 23,98), y el 12% de las leches eran deficientes. Se encontró diferencia estadísticamente significativa en los niveles medios de retinol en suero entre los lactantes alimentados con leches deficientes y adecuadas (0,85±0,16 μmol/L y 1,10±0,24 μmol/L, respectivamente; p=0,042). DISCUSIÓN: el estado nutricional de vitamina A de las madres fue adecuado, aunque el 12% de las leches fueron deficientes. El 5% de los lactantes presentaron DVA. Los niveles de retinol en suero de los lactantes alimentados con leches deficientes fueron inferiores al de los alimentados con leches adecuadas., INTRODUCTION: Breastfeeding mothers and infants are vulnerable groups to vitamin A deficiency (VAD). The aim of the study was to determine the relationship between the nutritional status of vitamin A in the mother and the exclusively breastfed infant. METHODS: An observational, analytical, cross-sectional study was carried out in 6-month-old breastfed infants and their mothers. Serum and milk vitamin A concentration was assessed by liquid chromatography. Average vitamin A concentrations and prevalences of VAD in serum and milk were calculated and compared using statistical tests. RESULTS: A total of 63 mother-child dyads were studied. The mean concentrations of retinol in maternal and infant serum were 1.84±0.48 μmol/L and 1.09±0.25 μmol/L, respectively. There were no mothers with VAD in serum, and 5% of the infants were deficient. The median concentration of retinol in breast milk was 15.57 μg/g fat (11.37; 23.98), and 12% were deficient. A statistically significant difference was found between serum retinol levels of infants fed adequate and deficient milk (0.85±0.16 μmol/L and 1.10±0.24 μmol/L, respectively; p=0.042). DISCUSSION: The nutritional status of vitamin A of the mothers was adequate, although 12% of the milk was deficient, and 5% of infants presented VAD. The serum retinol levels of infants fed poor milk were lower than those fed adequate milk., Facultad de Ciencias Exactas

El plomo es un metal neurotóxico ampliamente distribuido en el ambiente. Uno de los mecanismos de acción propuesto es su capacidad de inducir estrés oxidativo. Estudios experimentales en animales y observacionales en adultos expuestos ocupacionalmente han establecido una relación entre la exposición al plomo y alteraciones en biomarcadores de estrés oxidativo. Sin embargo la evidencia no es concluyente en poblaciones pediátricas expuestas ambientalmente al plomo. Objetivo: Determinar las plombemias de niños expuestos ambientalmente al plomo y establecer su relación con la actividad de enzimas antioxidantes y con el grado de peroxidación lipídica.

Introducción: La primera infancia es el período de mayor neuroplasticidad. La detección temprana de alteraciones del desarrollo permite la intervención oportuna para reducir secuelas y/o complicaciones. Objetivo: Evaluar el desarrollo psicomotor y cognitivo en lactantes asistidos en el sector público de salud, entre los 6 y 9 meses de edad. Población y métodos: Estudio descriptivo de seguimiento, de niños nacidos a término, clínicamente sanos en la evaluación, con peso, talla y perímetro cefálico adecuados para la edad. Se utilizó la Escala de Evaluación del Desarrollo Psicomotor y la Escala Argentina de Inteligencia Sensorio-motriz entre los 6 y 9 meses. En los casos en que se detectaron riesgo o retraso, se intervino con estimulación temprana. Se determinaron las prevalencias de riesgo/retraso del desarrollo psicomotor e inteligencia sensorio-motriz. Se utilizó el paquete estadístico R, versión 3.3.1. Resultados: Fueron evaluados 102 niños. A los 6 meses, el 22,5 % presentó riesgo/retraso en el desarrollo. Las prevalencias de resultados no esperados para la edad en desarrollo psicomotor y en inteligencia sensorio motriz fueron del 13,7 % y del 16,7 %, respectivamente. Estos niños recibieron estimulación temprana y todos mejoraron sus resultados. A los 9 meses, la prevalencia de riesgo/retraso fue del 20,6 %: el 14,7 % en desarrollo psicomotor y el 9,8 % en inteligencia sensorio motriz. Conclusión: El 22,5 % de los lactantes presentó riesgo/retraso del desarrollo a los 6 meses; la prevalencia a los 9 meses fue del 20,6 %. La evaluación temprana del desarrollo permitió detectar alteraciones e intervenir tempranamente. Introduction: Infancy is the period of greatest neuroplasticity. The early detection of developmental disorders helps to provide a timely intervention aimed at reducing sequelae and/or complications. Objective: To assess psychomotor and cognitive development in infants between 6 and 9 months old assisted in the public health sector. Population and methods: Descriptive study with follow-up of full-term infants who were clinically healthy at the time of assessment and had an adequate weight, height, and head circumference for their age. The Assessment Scale of Psychomotor Development and the Argentine Scale of Sensorimotor Intelligence were used in infants aged 6-9 months. Early stimulation was the intervention provided to those who showed a risk or delay. The prevalence of risk/delay of psychomotor development and sensorimotor intelligence was determined. The statistical software package R, version 3.3.1 was used. Results: A total of 102 children were assessed. At 6 months old, 22.5 % had a developmental risk/delay. The prevalence of unexpected results for age in psychomotor development and sensorimotor intelligence was 13.7 % and 16.7 %, respectively. These children received early stimulation and all showed improved results. At 9 months old, the prevalence of risk/delay was 20.6 %: 14.7 % in psychomotor development and 9.8 % in sensorimotor intelligence. Conclusion: At 6 months old, 22.5 % of infants had a developmental risk/delay; at 9 months old, this prevalence was 20.6 %. An early assessment of development helped to detect disorders and provide an early intervention.

El plomo es un metal tóxico para todos los seres vivos. Diversos estudios han demostrado la similitud de las condiciones de exposición y de sensibilidad a la contaminación por plomo de perros y niños, siendo estos últimos el principal grupo de riesgo humano. En razón de ello, la medición de los niveles de plombemia en perros puede servir como “indicador biológico precoz” o “indicador centinela” de posible exposición humana al plomo ambiental. Dado que en Argentina no existe un valor de referencia de plombemia para perros no expuestos a fuentes de contaminación, este estudio pretende contribuir a establecer dichos valores en la Cuenca Matanza Riachuelo. Es un estudio exploratorio, de prevalencia y corte transversal, realizado a través del análisis de plombemia de 365 perros. Las determinaciones se realizaron por espectrofotometría de absorción atómica con horno de grafito (límite de detección: 2 μg/dl; límite de cuantificación: 6 μg/dl). Las muestras de sangre se tomaron entre los meses de enero 2017 y enero 2018. La mayoría de las determinaciones mostró valores de plombemia no detectable (96 %). La prevalencia de plombemia superiores a 2 μg/dl y menores a 6 μg/dl fue del 3 %, y las mayores a 6 μg/dl del 1 %. Estos resultados constituyen un antecedente a fin de diseñar un sistema de evaluación y monitoreo de la contaminación con plomo ambiental de una manera ética, accesible, sensible, y a bajo costo, con impacto directo en poblaciones vulnerables y de riesgo ambiental. Lead is a metal that is toxic for all living beings. Various studies have shown there is a similarity of conditions of exposure and sensitivity to lead contamination between dogs and children, the latter being the main human group at risk. Because of this, the measurement of the blood lead level (BLL) in dogs can act as an ”early biological indicator”, or “early indicator”, of potential human exposure to environmental lead. Since in Argentina there is no reference BLL value for dogs which have not been exposed to sources of contamination, this study aims to correct this situation by calculating this value for the Matanza River Basin. It is an exploratory, cross-sectional/prevalence study that was carried out by analyzing the BLL of 365 canines. Determinations were made by graphite furnace atomic absorption spectrophotometry (GFAAS) (detection limit: 2 μg/dl; limit of quantification: 6 μg/dl). Blood samples were taken between the months of January 2017 and January 2018. Most of the determinations showed non-detectable BLL values (96 %) The prevalence of BLLs higher than 2 μg/dl and lower than 6 μg/dl was 3 %, and of BLLs higher than 6 μg/dl, 1 %. These results provide a background for designing a system to assess and monitor environmental lead contamination in an ethical, accessible, sensitive and cheap way that will have direct, positive impact on vulnerable populations at environmental risk. O chumbo é um metal muito tóxico para todos os seres vivos. Diversos estudos demonstraram a semelhança entre cães e crianças, das condições de exposição e sensibilidade à contaminação por chumbo, sendo as crianças o principal grupo de risco humano. Por esse motivo, a medição dos níveis de chumbo no sangue em cães pode servir como um “indicador biológico precoce” ou “indicador sentinela” de possível exposição humana ao chumbo ambiental. Como na Argentina não existe um valor de referência de níveis de chumbo no sangue para cães não expostos a fontes de contaminação, este estudo visa contribuir para o estabelecimento desses valores na Bacia do Riachuelo Matanza. Realizou-se um estudo exploratório, transversal de prevalência, através da análise de níveis de chumbo no sangue de 365 cães. As determinações foram feitas por Espectrofotometria de Absorção Atómica com forno de grafite (limite de deteção: 2 μg/dl, limite de quantificação: 6 μg/dl). As amostras de sangue foram recolhidas entre janeiro de 2017 e janeiro de 2018. A maioria das determinações revelou valores de chumbo não detetável (96 %). A prevalência de chumbo no sangue superior a 2 μg/dl e inferior a 6 μg/dl, foi de 3 %, e a prevalência superior a 6 μg/dl, foi de 1 %. Estes resultados constituem um achado, para a conceção de um sistema de avaliação e monitorização, da contaminação ambiental por chumbo, de maneira ética, acessível, sensível e de baixo custo, com impacto direto nas populações vulneráveis e no risco ambiental.

- Abstract
The aim of this article is to describe the nutritional status and eating patterns of children aged 1-3 years from low-income families who reside in areas with different productive activities: primary production and production of goods and services. A descriptive cross-sectional study was performed with a qualitative and quantitative methodology, evaluating anthropometric and biochemical nutritional status, food intake, economic and demographic characteristics, dietary practices and representations. The results show that children from areas of primary production had a lower prevalence of anemia and iron deficiency. They also had a higher consumption of energy, calcium, zinc, vitamin A and protein and a greater diversity and quality in food consumption. We can conclude that the geographical context of families closer to sources of primary production favors interaction with individuals outside of the family, expanding both the informal social network and access to better quality nutritional food, El objetivo de este artículo es describir el estado nutricional y los patrones de alimentación de niños de 1 a 3 años de familias de bajos recursos, que residen en dos áreas con diferentes actividades productivas: producción primaria y de bienes y servicios. Se realizó un estudio descriptivo de corte transversal, con metodología cuali-cuantitativa; se evaluó el estado nutricional antropométrico y bioquímico, ingesta alimentaria, características económicas y sociodemográficas, prácticas alimentarias y representaciones. Los resultados muestran que los niños del área de producción primaria presentaron menor prevalencia de anemia y deficiencia de hierro. Asimismo tuvieron un consumo superior de energía, calcio, zinc, vitamina A y proteínas y una mayor diversidad y calidad en el consumo de alimentos. Podemos concluir que el contexto geográfico de las familias que residen cerca de fuentes de producción primaria favorecería la interacción con individuos ajenos a la familia, ampliando la red social informal y el acceso a alimentos de mejor calidad nutricional.

Intoxicación por Plomo ,Pediatría ,exposición ambiental ,Deficiencia de Hierro - Abstract
Introducción: la deficiencia de hierro y la intoxicación por plomo afectan el crecimiento y el desarrollo neurológico de los niños. Numerosas publicaciones demuestran que ambas situaciones pueden asociarse. Además, ambos problemas son comunes en niños menores de 5 años, de bajos recursos y sometidos a contaminación ambiental. En Argentina la información disponible es escasa. Objetivo: establecer los niveles de plomo en sangre en niños y determinar si en nuestro medio existe asociación con la deficiencia de hierro y con factores de exposición al plomo. Materiales y métodos: se estudiaron 94 niños de 6 meses a 5 años que concurrieron a los consultorios externos del Hospital de Niños. Se determinaron plomo, ferritina y hemoglobina. Se realizó una encuesta socio-ambiental para evaluar factores de riesgo de exposición. Resultados: la concentración media de plomo en sangre fue de 5,4 μg /dl, con una prevalencia de niveles tóxicos de 10,6%. Se encontró asociación positiva entre deficiencia de hierro y niveles tóxicos de plomo (OR: 5,7). La actividad domiciliaria relacionada con plomo, la presencia de 5 o más factores de riesgo de exposición, el hecho de que el niño se enferme frecuentemente y tener un ingreso menor a 380$ se relacionó significativamente con niveles de plomo más altos. Conclusión: la deficiencia de hierro se asoció a niveles tóxicos de plomo. El 10.6% de los niños estudiados presentaron niveles considerados tóxicos. Dentro de los factores de exposición las actividades relacionadas con el manipuleo domiciliario del metal representaron el riesgo más importante de intoxicación por plomo.

Pediatría ,Salud ,Micronutrientes - Abstract
El impacto de la malnutrición de micronutrientes aparece en edades tempranas: lleva al retraso crónico del crecimiento, disminución de las capacidades cognitivas, letargia y pobre atención, y mayor tasa y severidad de infecciones. Este efecto limita el progreso educacional, la capacidad de trabajo físico y la expectativa de vida. La carencia de algunos nutrientes específicos, que no se manifiestan con signos de desnutrición constituyen lo que se ha denominado desnutrición oculta y existe en amplios sectores de la población con relativa independencia del estado nutricional y de la situación socio económica. La desnutrición oculta no es el resultado de un aporte insuficiente de energía y proteínas, sino la consecuencia de una alimentación inadecuada, no diversificada, marginal con relación a algún nutriente, lo cual determina que las reservas corporales resulten insuficientes para afrontar los esfuerzos de crecimiento, del embarazo, de la lactancia o de una infección. Estas deficiencias, que no pueden ser detectadas por la antropometría, pueden tener consecuencias de importancia para el presente o el futuro de los niños que la padecen. Por lo tanto la ingesta de cantidades adecuadas de micronutrientes es crítica en las etapas de mayores requerimientos. Dado la alta variabilidad de la prevalencia de deficiencia de micronutrientes condicionada por hábitos alimentarios, disponibilidad de alimentos, situación socio-económica, tradiciones culturales y religiosas, es necesario conocer las características regionales de las deficiencias para la posterior implementación de programas específicos tendientes a dar respuestas apropiadas a las mismas, como fue propuesto por países que realizaron un diagnóstico adecuado.

This study was conducted to evaluate the impact of a food aid program (Plan Más Vida, PMV) on the micronutrient nutritional condition of lactating mothers 1 year after its implementation. The food program provided supplementary diets (wheat- and maize-fortified flour, rice or sugar, and fortified soup) to low-income families from the province of Buenos Aires, Argentina. A prospective, non-experimental study was carried out to evaluate the micronutrient nutritional status of lactating mothers ( n = 178 at baseline and n = 151 after 1 year). Biochemical tests (hemoglobin, ferritin, zinc, vitamin A, and folic acid), anthropometric assessments (weight and height) and dietary surveys (24-h recall) were performed. We found no significant changes in anthropometric values 1 year after the intervention. The risk for vitamin A (retinol 20-30 μg/dl) and folate deficiency significantly decreased 1 year after PMV implementation (56.3 vs. 29.9 and 50.3 vs. 3.4 %, respectively; p < 0.001). Anemia was seen in 25.8 % of lactating mothers at baseline, without statistically significant differences 1 year after ( p = 0.439). The nutritional data obtained after assessing the early impact of PMV actions may be useful to provincial health authorities to perform periodic evaluations in the future. [ABSTRACT FROM AUTHOR]

- Abstract
Introduction. Iron deficiency (ID) is the most prevalent nutritional deficiency and the main cause of anemia in infants. There is consensus on daily iron supplementation as a preventive strategy; and weekly iron supplementation has also been shown to be effective, but evidence in infants is scarce. The objective of this study was to compare the effectiveness of daily versus weekly iron administration for the prevention of ID anemia (IDA) in infants. Population and methods. Randomized, controlled clinical trial. Infants seen at a public health center, without anemia at 3 months of age, were randomized into 3 groups: daily supplementation (1 mg/kg/day), weekly supplementation (4 mg/kg/week), or no supplementation (control group with exclusive breastfeeding [EB]). Anemia and ID were assessed at 3 and 6 months old. Adherence and adverse events were recorded. Data were analyzed using the R software, version 4.0.3. Results. A total of 227 infants participated. At 6 months, the group of infants with EB without supplementation (control) had a higher prevalence of ID and IDA than the intervention groups (daily and weekly). ID: 40.5% versus 13.5% and 16.7% (p = 0.002); IDA: 33.3% versus 7.8% and 10% (p < 0.001). There were no differences between the daily and weekly supplementation groups. There were also no differences in the percentage of high adherence to supplementation (50.6% daily versus 57.1% weekly) or adverse events. Conclusions. No significant differences in effectiveness were observed between daily and weekly administration for the prevention of infant IDA., (Sociedad Argentina de Pediatría.)

- Abstract
Introduction: Environmental exposure to lead is still a major public health problem, especially in children. Oxidative stress may be a primary mechanism associated with toxicity. The objective of this study was to measure blood lead levels (BLLs) in children aged 1 to 6 years exposed to lead in La Plata and suburban areas and their relation to oxidative stress biomarkers., Population and Methods: Cross-sectional, analytical study. Clinically healthy children aged 1 to 6 years were analyzed. BLLs, antioxidant enzyme activity, and extent of lipid peroxidation were measured. The statistical software package R, version 3.5.1, was used., Results: A total of 131 children participated; their median age was 2.33 years. The geometric mean of BLLs was 1.90 μg/dL; 32% showed a measurable BLL and 3%, BLLs ≥ 5 μg/dL (international reference). The comparison of oxidative stress biomarkers based on BLLs showed a significant difference in median thiobarbituric acid reactive substances (TBARS): 12.0 versus 10.0 nmol MDA/mL of plasma; p = 0.02. In addition, the correlation between BLLs and TBARS was positive (r = 0.24; p = 0.012)., Conclusions: Most children had a BLL below the limit recommended by international agencies; although such BLLs do not affect antioxidant enzyme activity, they can induce lipid peroxidation. These results demonstrate the usefulness of this biomarker as an early diagnosis tool to assess subtoxic lead effects., Competing Interests: None., (Sociedad Argentina de Pediatría.)

- Abstract
Introduction: Infancy is the period of greatest neuroplasticity. The early detection of developmental disorders helps to provide a timely intervention aimed at reducing sequelae and/or complications., Objective: To assess psychomotor and cognitive development in infants between 6 and 9 months old assisted in the public health sector., Population and Methods: Descriptive study with follow-up of full-term infants who were clinically healthy at the time of assessment and had an adequate weight, height, and head circumference for their age. The Assessment Scale of Psychomotor Development and the Argentine Scale of Sensorimotor Intelligence were used in infants aged 6-9 months. Early stimulation was the intervention provided to those who showed a risk or delay. The prevalence of risk/delay of psychomotor development and sensorimotor intelligence was determined. The statistical software package R, version 3.3.1 was used., Results: A total of 102 children were assessed. At 6 months old, 22.5 % had a developmental risk/delay. The prevalence of unexpected results for age in psychomotor development and sensorimotor intelligence was 13.7 % and 16.7 %, respectively. These children received early stimulation and all showed improved results. At 9 months old, the prevalence of risk/delay was 20.6 %: 14.7 % in psychomotor development and 9.8 % in sensorimotor intelligence., Conclusions: At 6 months old, 22.5 % of infants had a developmental risk/delay; at 9 months old, this prevalence was 20.6 %. An early assessment of development helped to detect disorders and provide an early intervention., Competing Interests: The authors report no conflicts of interest in this work., (Sociedad Argentina de Pediatría.)

- Abstract
Introduction: Vitamin A deficiency (VAD) has been recognized as an important public health problem in developing countries. Preschoolers account for risk groups within vulnerable populations. The objective of this study was to determine the prevalence of VAD and associated factors in a sample of preschoolers., Materials and Methods: Cross-sectional study with children aged 1-6 years receiving social assistance and seen at primary health care centers in the outskirts of the city of La Plata, Buenos Aires. Vitamin A levels were determined by measuring serum retinol with a liquid chromatography; anthropometric parameters and dietary intake were recorded. A multinomial logistic regression model was used to assess the association among outcome measures., Results: Data from 624 children were analyzed. The geometric mean of retinol was 23.8 pg/dL (95 % CI: 23.3-24.3). The prevalence of VAD and the risk for VAD were 24.3 % and 57.4 %, respectively. Retinol levels were significantly lower among boys, low-weight children, and those with low intake (below the first tertile of distribution). The multivariate analysis showed a significant association between VAD and male sex (odds ratio: 1.93; 95 % CI: 1.15-3.24) and between VAD and low intake (odds ratio: 1.48; 95 % CI: 1.15-2.62)., Conclusion: The prevalence of VAD (24.3 %) is a major public health problem in this population. VAD-associated factors were male sex and low vitamin A intake., (Sociedad Argentina de Pediatría.)

- Abstract
Introduction: Lead has neurotoxic effects in children, even at a very low level in blood. The risk factors (RFs) for lead exposure have not been adequately identified in La Plata. The objectives of this study were to determine mean blood lead levels and identify RFs in children aged 1 to 6 years old living in La Plata and the outskirts., Population and Methods: A cross-sectional study was conducted in children who attended primary health care centers for a health check-up. Blood lead levels were determined by atomic absorption spectroscopy, and a socioenvironmental survey was administered to outline RFs. The Mann-Whitney test was used to compare measurements. A multivariate statistical analysis was done to establish the most relevant RFs., Results: A total of 319 children participated (51% were boys); the median (interquartile range) blood lead level was 2.2 pg/dL (1.1-3.6 pg/dL). Significant mean differences in blood lead levels were observed for age≤ 3years old, anemia, pica behavior, overcrowding, dirt floors, and maternal education < 7 years. Age≤ 3years old and pica behavior were both RFs with significant odds ratios (ORs). The OR as adjusted by logistic regression was significant only for age≤ 3years old., Conclusions: The median blood lead level in the studied population was 2.2 pg/dL. The main RFs identified for lead exposure were age≤ 3years old and pica behavior. Other less relevant RFs included anemia, maternal education < 7 years, overcrowding, and dirt floors., (Sociedad Argentina de Pediatría)

- Abstract
The aim of this article is to describe the nutritional status and eating patterns of children aged 1-3 years from low-income families who reside in areas with different productive activities: primary production and production of goods and services. A descriptive cross-sectional study was performed with a qualitative and quantitative methodology, evaluating anthropometric and biochemical nutritional status, food intake, economic and demographic characteristics, dietary practices and representations. The results show that children from areas of primary production had a lower prevalence of anemia and iron deficiency. They also had a higher consumption of energy, calcium, zinc, vitamin A and protein and a greater diversity and quality in food consumption. We can conclude that the geographical context of families closer to sources of primary production favors interaction with individuals outside of the family, expanding both the informal social network and access to better quality nutritional food.

- Abstract
Introduction. Anemia is a public healthcare problem that particularly affects children under the age of 2 years, with consequences that greatly affect psychomotor and intellectual growth during childhood and productive capacities in adulthood. Objective. To study the prevalence of anemia, its variations and possibly associated factors in children under 6 months of age. Material and methods. Cross-sectional descriptive study analyzing health records of 363 children aged 4-5 months assisted in the period 2007-2010. We determined the association of anemia (hemoglobin <10,3 g/dl) with feeding (exclusive breastfeeding and mixed feeding), type of birth and sex. Birth weight means and z-scores for weight-for-age, height-for-age, and weight-for-height were compared in anemic versus non-anemic children. Results. Anemia was present in 28.9% (105/363) of children, being its prevalence significantly higher in boys (38.3% versus 20.9%; p= 0.000). There were no significant differences in type of birth or feeding. Mean birth weight and mean z-score for weight-for-age, height-for-age and weight-for-height was significantly lower in anemic vs. non-anemic children. We found a significant reduction in anemia (37.8% in 2007 to 20.3% in 2010 during the study period, p= 0.012) Conclusion. The prevalence of anemia was 28.9%; decreased significantly between 2007 and 2010, and represents a serious public healthcare problem. The prevalence was higher in boys, in children with lower birth weight and in those with lower antropometric indices. Our results, even though local, reflect the high nutritional risk of the population under 6 months of age.

- Abstract
Introduction: Environmental exposure to lead and the subsequent poisoning are a main public health concern worldwide. Children have a higher vulnerability to lead toxic effects, and many reports have shown the association between iron deficiency and lead poisoning. In Argentina, reports about lead levels in children are scarce. Our aims were to assess blood lead levels in children and determining their relationship with iron deficiency and known lead exposure risk factors., Material and Methods: We performed a cross-sectional study in a sample of 93 children (age range, 6 months to 5 years) receiving care at La Plata Children s Hospital. A social and environmental survey was done, and blood lead, hemoglobin and ferritin levels were assessed., Results: Geometric mean blood lead level was 4.26 microg/dl (95% CI, 3.60-5.03); prevalence of blood lead levels >or=10 microg/dl was 10.8%. Higher blood lead levels were found in children living in households with lead-handling contaminating activities (6.74 vs. 3.78 microg/dl; p= 0.005) and in very low-income households (5.68 vs. 3.71 microg/ dl; p= 0.020). The presence of blood lead levels >or=10 microg/dl was strongly associated with iron deficiency (OR 5.7; 95% CI: 1.34-23.41) and with lead-handling activities at home (OR 4.8; 95% CI: 1.12-20.16)., Conclusion: The prevalence of blood lead levels >or=10 microg/dl is a matter of concern in the population studied. Iron deficiency and development of lead-handling activities at home were the risk factors associated with high blood lead levels.
