Diversidad de dieta y anemia en mujeres post parto que asisten a un hospital público de La Plata, Buenos Aires / Diet diversity and anemia in postpartum women attending a state hospital in La Plata, Buenos Aires

Resumen Introducción: no se cuenta con información a nivel local de la relación entre la diversidad de dieta y la anemia en mujeres postparto, por lo que se propuso analizar dicha relación en un hospital público de La Plata. Materiales y método: se realizó un estudio analítico transversal en mujeres asistidas durante el primer año postparto, en un Observatorio de Salud del Hospital Sor María Ludovica de la ciudad de La Plata, entre agosto de 2018 y septiembre de 2019. Se obtuvieron datos personales y de laboratorio de las historias clínicas. Los alimentos relevados mediante recordatorios de 24 hs fueron categorizados en 10 grupos. Se consideró diversidad de dieta al consumo ≥5 grupos según el instrumento "Mínimo de diversidad dietaria para mujeres". Se definió anemia como hemoglobina <12 g/dL. La asociación entre la anemia y diversidad de dieta se analizó mediante test exacto de Fisher y se comparó la media de hemoglobina utilizando test de Student. Resultados: se incluyeron 137 mujeres postparto, edad 26 (22;31) años, 53,7% argentinas. 12,4% presentó anemia. 63,5% tuvo diversidad de dieta. "Granos y cereales" fue el grupo más consumido (100%), seguido por "Carne, pollo y pescado" (92,7%) y "Otros vegetales" (85,4%). Los menos consumidos fueron "Legumbres" (6,6%) y "Nueces y semillas" (0,7%). No se halló una asociación estadísticamente significativa entre diversidad de dieta y anemia (p=0,18). Tampoco se halló diferencia en las medias de hemoglobina en mujeres con y sin diversidad de dieta (p=0,99). Conclusiones: la diversidad de dieta no se halló asociada a anemia en mujeres postparto que asisten a un hospital público, esto podría relacionarse a la alta frecuencia de consumo de carnes y cereales fortificados.

Abstract Introduction: there is no information at local level on the relationship between diet diversity and postpartum anemia of women, so we intended to analyze this relationship in a state hospital in La Plata. Materials and method: a cross-sectional analytical study was carried out in women assisted during the first year postpartum, in the Health Observatory of Sor María Ludovica Hospital in La Plata city, between August 2018 and September 2019. Personal and laboratory data were obtained from medical records. Foods surveyed by 24-hour reminders were categorized into 10 groups. Dietary diversity was considered to be the consumption ≥5 groups, according to the "Minimum dietary diversity for women" instrument. Anemia was defined as hemoglobin <12 g / dL. The association between anemia and diet diversity was analyzed using Fisher's exact test and mean hemoglobin was compared using Student's test. Results: 137 postpartum women were included, age 26 (22; 31), 53.7% Argentinian. 12.4% presented anemia. 63.5% had diet diversity. "Grains and cereals" was the most consumed group (100%), followed by "Meat, chicken and fish" (92.7%) and "Other vegetables" (85.4%). The least consumed were "Legumes" (6.6%) and "Nuts and seeds" (0.7%). No statistically significant association was found between diet diversity and anemia (p = 0.18). No difference was found in the hemoglobin means in women with and without diet diversity (p = 0.99). Conclusions: diet diversity was not associated with anemia in postpartum women attending a state hospital, this could be related to the high frequency of consumption of meats and fortified cereals.

Hierro y ácido fólico: natural, enriquecido, fortificado y suplementos. Análisis de las fuentes alimentarias en la Ciudad de Buenos Aires / Iron and folic acid: natural, enriched, fortified, and supplements. Analysis of food sources in the Autonomous City of Buenos Aires

Introducción. La fortificación y suplementación son estrategias para la prevención de carencias de micronutrientes. El objetivo fue describir la procedencia de la ingesta del hierro y ácido fólico a lo largo del ciclo vital de la población de la Ciudad Autónoma de Buenos Aires. Población y métodos. Análisis de la información de la Primera Encuesta Alimentaria y Nutricional de la Ciudad Autónoma de Buenos Aires 2011, que tomó una muestra probabilística por conglomerados. El consumo se recabó con recordatorio de 24 horas. Se calculó el aporte de hierro y ácido fólico, y se categorizó en contenido natural, harina de trigo enriquecida, leche del Plan Materno Infantil, alimentos fortificados y suplementos. Resultados. De los 5369 individuos evaluados, prácticamente, la totalidad obtenía hierro y ácido fólico de contenido natural (el 58 % y el 29 % del consumo, respectivamente). Más del 90 % consumía harina de trigo enriquecida, que aportaba el 28 % del hierro y el 54 % del ácido fólico. Los alimentos fortificados mostraron consumo y aporte muy variable. La leche del Plan Materno Infantil mostró muy baja participación, inclusive en grupos específicos. El aporte de suplementos fue bajo, excepto en < 2 años (el 30 % consumía suplementos de hierro, que aportaban el 38 % de este).Conclusión. Además del aporte natural de los alimentos, la harina de trigo enriquecida representó una importante contribución en el consumo de ácido fólico y hierro de esta población; los alimentos fortificados y los suplementos tuvieron una participación diferente según el grupo etario.

Introduction. Fortification and supplementation are two strategies for micronutrient deficiency prevention. The objective of this study was to describe the source of iron and folic acid intake throughout the life cycle in the population of the Autonomous City of Buenos Aires.Population and methods. Analysis of the information collected in the First Survey on Nutritional Food Intake of the Autonomous City of Buenos Aires (2011), which had a probability cluster sampling design. Consumption was assessed by means of a 24-hour recall. Iron and folic acid intake was estimated and categorized into natural content, enriched wheat flour, milk from the Maternal and Child Plan, fortified foods, and supplements.Results. Out of the 5369 studied individuals, practically all got iron and folic acid from natural contents (58 % and 29 % of intake, respectively). More than 90 % consumed enriched wheat flour, which provided 28 % of iron and 54 % of folic acid. Fortified food consumption and intake varied greatly. Milk intake from the Maternal and Child Plan was small, even in specific groups. Intake from supplements was low, except in children < 2 years old (30 % consumed iron supplements, which accounted for 38 % of iron).Conclusion. In addition to natural intake from foods, enriched wheat flour accounted for a major source of folic acid and iron in this population; intake from fortified foods and supplements varied by age group.

Nutritional composition and acceptance of cake elaborated with beauregard potato biofortified with carotenoids / Composição nutricional e aceitação de bolo elaborado com batata beauregard biofortificada com carotenoides

Beauregard biofortified sweet potato is a tuberous root with a high content of carotenoids whose consumption can bring beneficial effects on human health related to the biological actions of these substances. The objectives of this study were to evaluate the acceptance of cake made with sweet potato biofortified with carotenoids by school children enrolled in a school of the municipal education network of the city of Teresina PI. The sweet cake containing biofortified potato (Beauregard) (PC) was compared with standard sweet wheat flour (WC) cake formulation. The PC and WC products and the Beauregard potato were analyzed for centesimal composition (moisture, ashes, proteins, lipids and carbohydrates) and total carotenoid content. Acceptance of PC was assessed by means of an acceptance test with a hedonic scale of five points applied to 100 children from 08 to 10 years of age. The evaluation of the centesimal composition showed protein content corresponding to 2.1% in WC and 3.57% in PC, and of lipids of 5.16% in WC and 8.95% inPC. Regarding the moisture content, WC presented 32.5% and PC 38.44%. The content of fixed minerals (ash) found in formulations was 1.9% and 1.26%, respectively, in WC and PC. The carotenoid content (µg of ß-carotene.g-1) was significantly higher (p <0.05) in the biofortified potato (3,200.01 ± 0.02) and in the PC formulations (3,666.17 ± 2.55) and WC (3,066.53 ± 1.88) for common sweet potatoes (2.200,23 ± 1.63). In the five-point facial hedonistic acceptance test, the formulation containing biofortified potato (PC) obtained a significantly higher score (p <0.05) (4.24 ± 0.93) when compared to the WC formulation (3.75 ± 1.19). The biofortified potato and the cake containing the biofortified potato presented some characteristics related to the centesimal composition similar to those found in WC and the content of carotenoids in PC larger than those of WC. Because sweet cake is a food product, generally well accepted by children and adults, PC's greateracceptance of WC suggests its promising potential for consumption by the population.

A batata-doce Beauregard biofortificada é uma raiz tuberosa com alto teor de carotenoides, cujo consumo pode trazer efeitos benéficos na saúde humana relacionados com as ações biológicas dessassubstâncias. Os objetivos deste estudo foram avaliar a aceitação de bolo elaborado com batata doce biofortificada com carotenoides por crianças em idade escolar matriculados em uma escola da rede municipal de ensino da cidade de Teresina PI. O bolo doce contendo batata biofortificada (Beauregard) (BB) foi comparado com formulação padrão de bolo doce de farinha de trigo (BT). Os produtos BB e BT e a batata Beauregard foram analisados quanto à composição centesimal (umidade, cinzas, proteínas, lipídeos e carboidratos) e conteúdo de carotenóides totais. A aceitação do BB foi avaliada por meio de teste de aceitação com escala hedônica facial de cinco pontos aplicado em 100 crianças de 08 a 10 anos de idade. A avaliação da composição centesimal mostrou conteúdo protéico correspondendo 2,1% no BT e 3,57% no BB, e de lipídiosde 5,16% no BT e 8,95% no BB. Em relação ao teor de umidade, o BT apresentou 32,5% e BB 38,44%. O teor de minerais fixos (cinzas) encontrado nas formulações foi de 1,9% e 1,26%, respectivamente, no BT e BB. O conteúdo de carotenoides (µ g de ß-caroteno.g-1) foi significativamente maior (p<0,05) na batata biofortificada (3.200,01 ± 0,02) e nas formulações BB (3.666,17 ± 2,55) e BT (3.066,53 ± 1,88) em relação à Figure 1. Acceptance rate of Beauregard potato and wheat cake formulations.. batata doce comum (2.200,00 ± 1,63). No teste de aceitação escala hedonica facial de cinco pontos a formulação contendo batata biofortificada (BB) obteve nota significativamente maior (p<0,05) (4,24± 0,93) quando comparada com a formulação BT (3,75± 1,19). A batata biofortificada e o bolo contendo a batata biofortificada apresentaram algumas características relacionadas à composição centesimal semelhantes àquelas encontradas no BT e conteúdo de carotenoides no BB maiores que os do BT. Por ser o bolo doce um produto alimentício, de modo geral, bem aceito por crianças e adultos, a maior aceitação do BB em relação ao BT sugere seu potencial promissor para consumo pela população.

Impacto del Ácido Fólico en la Incidencia de Fisuras Labiopalatinas de la Población Occidente de la Región Metropolitana, Chile / Impact of Folic Acid on the Incidence of Cleft Lip and Palate of the Western Population of the Metropolitan Region, Chile

RESUMEN: La fisura labiopalatina ha tenido una alta frecuencia en la población chilena. A partir del 2000 se inició el programa de fortificación de la harina con ácido fólico a fin de disminuir los defectos del tubo neural. El objetivo de este estudio fue determinar el impacto que presenta la incorporación del ácido fólico en la incidencia de fisuras labiopalatinas de la población del área occidente de la Región Metropolitana. Se recopiló información a partir de las fichas clínicas de la Fundación Gantz seleccionando a los recién nacidos entre 1990 y 2009, correspondientes a las comunas del Servicio de Salud Occidente de la Región Metropolitana. Desde el 2000 hasta el 2004 se observó una disminución importante en las tasas de fisura labiopalatina, con una tasa de 0,88 fisurados por 1000 recién nacidos vivos. Posteriormente se observó un incremento a partir del 2005 hasta el 2009 llegando a una tasa de 1,52 fisurados por 1000 recién nacidos vivos. En conclusión, el efecto protector del ácido fólico se evidencia en la disminución de las tasas de los recién nacidos con fisuras durante los primeros años de su implementación. Sin embargo, posteriormente se observó un aumento de dichas tasas, lo cual podría deberse al incumplimiento de la norma.

ABSTRACT: Cleft lip and palate has had a high frequency in the Chilean population. From the year 2000 a flour fortification program with folic acid was initiated in order to reduce the defects of the neural tube. The objective of this study was to determine the impact of the incorporation of folic acid in the incidence of cleft lip and palate of the population of the western area of the Metropolitan Region. Information was collected from clinical records of the Gantz Foundation, selecting newborns from 1990 to 2009, corresponding to the districts of the western sector of the Metropolitan Region. From 2000 to 2004 there was a significant decrease in cleft lip and palate rates, with a rate of 0.88 cases per 1000 live births. Subsequently, an increase was observed from 2005 to 2009, reaching a rate of 1.52 cases per 1000 live births. In conclusion, the protective effect of folic acid is evidenced in the reduction of the rates of newborns with cleft palate during the first years of its implementation. However, an increase in these rates was subsequently observed, which could be due to noncompliance with the standard.

EVALUACIÓN DE DIFERENTES CONDICIONES DE PROCESO EN LA FORTIFICACIÓN DE MANGO (Tommy Atkins) CON CALCIO MEDIANTE IMPREGNACIÓN A VACÍO / EVALUATION PROCESS IN DIFFERENT CONDITIONS OF MANGO FORTIFICATION (Tommy Atkins) WITH CALCIUM BY VACUUM IMPREGNATION

La impregnación al vacío es una tecnología eficaz para la incorporación de compuestos fisiológicamente activos (CFA) en la matriz porosa de un alimento dentro del marco de los mínimamente procesados, proporcionando nuevas categorías de productos funcionales que responden a las necesidades de mejorar la calidad nutricional de la población con carencia en micronutrientes. Fueron utilizados cilindros de mango fresco impregnados a vacío con una solución de lactato de calcio 6% y cloruro de calcio 1%. Las condiciones del proceso (presión y tiempo de vacío) y tamano de la muestra fueron definidas a través del estudio cuyas interacciones afectaron significativamente los parámetros de impregnación X y 8e. La técnica permitió incorporar un 37,6% de la Ingesta Diaria Recomendada (IDR) de calcio en 200 g de mango fresco, variedad Tommy Atkins, sin afectar las características sensoriales del producto final. La determinación de calcio fue realizada por espectrofotometría de absorción atómica. El proceso generó pérdidas de líquidos nativos, expansión de la fruta y disminución de los valores de X y 8e por la presencia de iones calcio en el mango impregnado.

Vacuum impregnation is an effective technology for the incorporation of physiologically active compounds in a food porous matrix within the framework of minimally processed, providing new productfunctionality to meet the needs of improving the nutritional quality of micronutrient-deficient populations. Fresh mango cylinders were vacuum impregnated with a solution of calcium lactate 6 %% and 1 % calcium chloride, the process conditions (pressure and vacuum time) and sample size were defined by studying the interactions of which significantly affected parameters X and ee impregnation. The technique allowed the incorporation of37.6% (recommended daily intake) RDA of calcium in 200 g of fresh mango, variety Tommy Atkins, without affecting the sensory characteristics of the final product. The determination of calcium was performed by atomic absorption spectrophotometry. Process generated native fluid losses, expansion offruit and low levels ofX and ee by the presence of calcium ions in the soaked mango.

La anemia por deficiencia de hierro en la población infantil de Cuba. Brechas por cerrar / Iron deficiency anemia in the child population of Cuba. Gaps to be bridged

La anemia es un problema de salud mundial que afecta tanto a los países desarrollados como a aquellos en desarrollo. Sus causas pueden ser multifactoriales y frecuentemente pueden coexisitir varias de ellas; la principal es la baja ingestión de alimentos con fuentes adecuadas de hierro, tanto en cantidad como en calidad. En Cuba se está trabajando desde el año 1987 en el desarrollo de programas de intervención para la prevención de la anemia por deficiencia de hierro en la población, pero a pesar de todo el esfuerzo, no se han obtenido los impactos esperados, y existen diversos factores que pueden estar incidiendo en ello y que pueden sinergizarse. Evidencias científicas nacionales muestran que la baja prevalencia de lactancia materna, el escaso consumo de frutas y vegetales y la deficiencia vitamínica, ejercen influencia en la prevalencia de la anemia en Cuba. El parasitismo intestinal y la infección con H. pylori no están asociados con la prevalencia de anemia en el país. La obesidad e inflamación crónica a bajo tenor requerirían de estudios epidemiológicos que describan las posibles asociaciones entre estos factores

Anemia is a global health problem affecting both developed and developing countries. The causes of anemia may be multifactorial, and several of them are often present at the same time. The main cause of anemia is the low intake of foods with adequate sources of iron both in quantity and quality. Work is being done in Cuba since the year 1987 aimed at developing intervention programs for the prevention of iron deficiency anemia in the population, but despite the great effort, the expected impact has not been achieved, due to the combined influence of various factors. National scientific evidence shows that the low incidence of breastfeeding, the low intake of fruits and vegetables, as well as vitamin deficiency, have an influence on the prevalence of anemia in Cuba. Neither intestinal parasitism nor infection with H. pylori are associated with the prevalence of anemia in the country. Obesity and chronic inflammation would require epidemiological studies describing the potential relationships between these factors
