Relación entre niveles de vitamina D y perfil lipídico en embarazadas de alto riesgo / Relationship between level of vitamin D and lipid profile in high risk pregnant women

En la Argentina, las embarazadas presentan alta prevalencia (80%) de hipovitaminosis D y de sobrepeso u obesidad (27,4%). Ambas condiciones pueden aumentar la morbimortalidad materno-fetal. Bajos niveles de vitamina D se han relacionado con aumento del colesterol total, LDL, triglicéridos (Tg) y descenso de HDL. Objetivo: evaluar los niveles de 25-hidroxivitamina D (25OHD) y su relación con el perfil lipídico en pacientes embarazadas de alto riesgo. Materiales y métodos: estudio de corte transversal entre septiembre de 2016 y abril de 2017. Se excluyeron pacientes que recibieron suplementos de vitamina D, con disfunción tiroidea no compensada, malabsorción, insuficiencia cardíaca, renal o hepática y dislipidemia familiar. Niveles circulantes de 25OHD < 30 ng/ml se consideraron hipovitaminosis. Resultados: se evaluaron 86 embarazadas de 29,3 ± 7,1 años durante la semana 28 ± 6,5. El IMC pregestacional fue 28,3 ± 6,5 kg/m2 y la ganancia de peso 7 ± 4,3 kg. Perfil lipídico: colesterol total 240 ± 54 mg/dl; LDL 156 ± 54 mg/dl; HDL 66 ± 15 mg/dl; Tg 204 ± 80 mg/dl. La media de 25OHD fue de 23,8 ± 9 ng/ml, con una prevalencia de hipovitaminosis D de 77,9 %. Las pacientes con hipovitaminosis D presentaron mayores valores de colesterol total y LDL (p < 0,05), con tendencia no significativa a presentar mayores valores de Tg. Conclusión: en embarazadas de alto riesgo se observó una alta prevalencia de hipovitaminosis D, asociada con mayores concentraciones de colesterol total y LDL. (AU)

In Argentina, pregnant women have a high prevalence (80 %) of hypovitaminosis D and verweight/obesity (27.4%), conditions that can increase maternal-fetal morbidity and mortality. Low levels of 25-hydroxyvitamin D (25OHD) have been linked to an increase in total cholesterol, LDL cholesterol, triglycerides (TG) and a decrease in HDL cholesterol. Objective: to evaluate the levels of vitamin D and its relationship with the lipid profile in high risk pregnant patients. Materials and methods: cross-sectional study between September 2016 and April 2017. Patients who received vitamin D supplements or had non-compensated thyroid dysfunction, malabsorption, heart failure, renal or hepatic failure, or familial dyslipidemia were excluded. Hypovitaminosis D was defined as a circulating level of 25OHD < 30 ng/ml. Results: We assessed 86 women of 29.3 ± 7.1 years during pregnancy week 28 ± 6.5. Pre-gestational BMI was 28.3 ± 6.5 kg/m2. Their weight gain was 7 ± 4.3 kg. Lipid profile: total cholesterol 240 ± 54 mg/dl; LDL cholesterol 156 ± 54 mg/dl; HDL cholesterol 66 ± 15 mg/dL; TG 204 ± 80 mg/dl. The mean 25OHD level was 23.8 ± 9 ng/ml, with a 77.9 % prevalence of hypovitaminosis D. Patients with hypovitaminosis D had higher values of total cholesterol and LDL cholesterol (p<0.05), and a non-significant trend toward higher triglyceridemia. Conclusion: A high prevalence of hypovitaminosis D, associated with high total and LDL cholesterol was found in high risk pregnant women. (AU)

Factors associated with the nutritional status of children less than 5 years of age / Fatores associados ao estado nutricional de crianças menores de cinco anos

OBJECTIVE To analyze if the nutritional status of children aged less than five years is related to the biological conditions of their mothers, environmental and socioeconomic factors, and access to health services and social programs.METHODS This cross-sectional population-based study analyzed 664 mothers and 790 children using canonical correlation analysis. Dependent variables were characteristics of the children (weight/age, height/age, BMI/age, hemoglobin, and retinol serum levels). Independent variables were those related to the mothers' nutritional status (BMI, hemoglobin, and retinol serum levels), age, environmental and socioeconomic factors and access to health service and social programs. A < 0.05 significance level was adopted to select the interpreted canonical functions (CF) and ± 0.40 as canonical load value of the analyzed variables.RESULTS Three canonical functions were selected, concentrating 89.9% of the variability of the relationship among the groups. In the first canonical function, weight/age (-0.73) and height/age (-0.99) of the children were directly related to the mother's height (-0.82), prenatal appointments (-0.43), geographical area of the residence (-0.41), and household incomeper capita (-0.42). Inverse relationship between the variables related to the children and people/room (0.44) showed that the larger the number of people/room, the poorer their nutritional status. Rural residents were found to have the worse nutritional conditions. In the second canonical function, the BMI of the mother (-0.48) was related to BMI/age and retinol of the children, indicating that as women gained weight so did their children. Underweight women tended to have children with vitamin A deficiency. In the third canonical function, hemoglobin (-0.72) and retinol serum levels (-0.40) of the children were directly related to the mother's hemoglobin levels (-0.43).CONCLUSIONS Mothers and children were associated concerning anemia, vitamin A deficiency and anthropometric markers. Living in rural areas is a determining factor for the families health status.

OBJETIVO Analisar se o estado nutricional de crianças menores de cinco anos está relacionado a condições biológicas de suas mães, a fatores ambientais e socioeconômicos e ao acesso a serviços de saúde e programas sociais.MÉTODOS Este estudo transversal, de base populacional, analisou 664 mães e 790 filhos, utilizando análise de correlação canônica, tendo como variáveis dependentes as características dos filhos (peso/idade, estatura/idade, índice de massa corporal/idade, níveis de hemoglobina e retinol sérico). Como variáveis independentes, as relacionadas ao estado nutricional das mães (índice de massa corporal, níveis de hemoglobina e retinol sérico), idade materna, fatores ambientais, socioeconômicos, acesso a serviços de saúde e programas sociais. Adotou-se nível de significância < 0,05 para seleção das funções canônicas interpretadas e ± 0,40 como valor de carga canônica das variáveis analisadas.RESULTADOS Foram selecionadas três funções canônicas, concentrando 89,9% da variabilidade da relação entre os grupos. Na primeira, peso/idade (-0,73) e estatura/idade (-0,99) dos filhos relacionaram-se diretamente com estatura materna (-0,82), consultas pré-natais (-0,43), área geográfica de moradia (-0,41) e renda familiar per capita (-0,42). A relação inversa entre variáveis referentes aos filhos e moradores/cômodo (0,44) mostrou que, quanto maior o número de pessoas/cômodo, mais deficiente o estado nutricional. Residentes na área rural apresentaram piores situações nutricionais. Na segunda função, índice de massa corporal materno (-0,48) relacionou-se com índice de massa corporal/idade e retinol dos filhos, indicando que, à medida que as mulheres aumentavam de peso, o mesmo acontecia com seus filhos e que mulheres de baixo peso tendiam a ter filhos com deficiência de vitamina A. Na terceira função, os níveis de hemoglobina (-0,72) e retinol (-0,40) dos filhos estiveram diretamente relacionados ao nível de hemoglobina materna (-0,43).CONCLUSÕES Mães e filhos estavam associados em relação à anemia, deficiência de vitamina A e marcadores antropométricos. Residir na área rural ainda é um discriminante na situação de saúde das famílias.

Asociación entre la ingesta de nutrientes hematopoyéticos y el origen nutricional de la anemia en mujeres en edad fértil en Colombia / Association between hematopoietic nutrient intake and the origin of nutritional anemia in women of childbearing age in Colombia

OBJETIVO: Comparar el origen de la anemia nutricional según las variables sociodemográficas y analizar su asociación con la deficiencia en la ingesta de nutrientes hematopoyéticos. MÉTODOS: Se utilizó la base de datos de la Encuesta Nacional de la Situación Nutricional de Colombia, 2005. Los datos se obtuvieron por muestreo complejo representativo de la población y se procesaron con el programa SPSS, v.15. Se seleccionaron mujeres en edad fértil con anemia y se clasificaron en dos grupos según la ferritina sérica. Se determinó la ingesta usual de nutrientes hematopoyéticos y el riesgo de deficiencia. Se compararon las proporciones de los tipos de anemia según las variables sociodemográficas utilizando la prueba F de Rao-Scott de segundo orden (P < 0,05). Se analizó la asociación entre el origen de la anemia y la clasificación del nutriente mediante la razón de posibilidades (odds ratio, OR). RESULTADOS: Muestra: 595 mujeres. Predominó la anemia no ferropénica (67,2 por ciento), sin diferencia estadística por variables sociodemográficas, excepto en la región Pacífica (anemia ferropénica, 52,1 por ciento). La prevalencia de la deficiencia en la ingesta usual de nutrientes hematopoyéticos fue alta. No se encontró asociación significativa entre el déficit de consumo y el origen de la anemia. CONCLUSIONES: La anemia no ferropénica fue más frecuente, sin diferencia según los indicadores sociodemográficos excepto en la región Pacífica. Todas las mujeres presentaron alto riesgo de deficiencia en la ingesta usual de nutrientes hematopoyéticos, pero no se observó una asociación estadísticamente significativa entre la deficiencia y el origen de la anemia nutricional. Se justifica implementar programas orientados a mejorar el aporte de nutrientes y continuar la búsqueda de otras causas de la anemia nutricional diferentes a la deficiencia de hierro.

OBJECTIVES: Compare the nutritional origin of anemia by sociodemographic variables and analyze its association with deficient hematopoietic nutrient intake. METHODS: The database of Colombia's 2005 National Survey of Nutritional Status was used. The data were obtained through complex representative sampling of the population and processed using SPSS v.15. Anemic women of childbearing age were selected and divided into two groups according to serum ferritin levels. Their customary hematopoietic nutrient intake and risk of deficiency were determined. The proportions of anemia types were compared by sociodemographic variables using the F-distribution, the Rao-Scott second order correction (P < 0.05). The association between the origin of the anemia and classification of the nutrient was analyzed using the odds ratio (OR). RESULTS: Sample: 595 women. Non-hypoferric anemia (67.2 percent) predominated, with no statistical difference by sociodemographic variable, except in the Pacific region (hypoferric anemia, 52.1 percent). The prevalence of deficiency in the customary intake of hematopoietic nutrients was high. There was no significant association between the deficit in consumption and the origin of the anemia. CONCLUSIONS: Non-hypoferric anemia was most common, with no difference by sociodemographic indicators except in the Pacific region. All the women were at high risk of deficiency in their customary hematopoietic nutrient intake, but a statistically significant association between the deficiency and the origin of the nutritional anemia was not observed. Programs to improve nutrient intake and a continued search for causes of nutritional anemia other than iron deficiency are justified.

Impact of NGO run mid day meal program on nutrition status and growth of primary school children.

Objective. To study the impact of wholesome mid day meal (MDM) program run by an NGO on the growth of the primary school students in rural area of Mathura district. Methods. This intervention study involved children enrolled in Government run rural primary schools in Mathura district in Uttar Pradesh from March 06 through August 07. A wholesome, nutritionally balanced MDM provided by an NGO for the students in the 6 primary schools was selected as intervention group. Control group consisted of children in 8 schools which received locally prepared MDM by village panchayats. Height, weight, change in height/month, change in weight/month, prevalence of protein-energy malnutrition and prevalence of signs of vitamin deficiencies, were measured. Results. Food was provided for 221 days in one year. Within group and between groups repetitive measures were compared using generalized estimating equation (GEE). Within both intervention and control groups height and weight had significantly increased (p < 0.05), while there was no significant difference between the groups. There was no change in prevalence of malnutrition within either of the groups. Reduction in vitamin A deficiency signs was 38% more in intervention group (p < 0.001). Prevalence of Vitamin D deficiency reduced by 50% more in intervention group. No such differences between groups were observed for vitamin B complex and vitamin C. Conclusions. MDM provided by the NGO has no better impact on growth of the primary school children, however, it reduced prevalence of vitamin deficiency significantly in comparison to the MDM run by Village Panchayats.

Serum levels of vitamin A and E in children in the Gezira State-Central Sudan

In a nutritional survey carried out on children in Gezira, Central Sudan, blood samples were taken from 80, randomly selected school children [43 males and 37 females] aged between 8 and 15 years. Twenty five males and 27 females were from central Sudan region and 18 males and 10 females were from Western Sudan origin. Specimens were separated by centrifugation at 3000 rpm and sera were sent frozen at minus 20 Celsius to Leeds General Infirmary. United Kingdom. All sera were tested for HIV and proved to be negative. Applying chromatographic methods, the levels of vitamin A and E were detected. With vitamin A normal range between 20-50 microgram/100 ml, deficiency of vitamin a was found in 40.0% of children of central Sudan region. Deficiency among children from Western Sudan origin was 46.0% with mean + S.D.5+ 14 and 4+ 13 microgram/ 100 mL respectively. Vitamin E was measured in 86 children [48 males and 38 females]. Normal range is 3.3-5.0 mg/ 100 mL. Deficiency of vitamin E was found in 9.3% of all children. It is more among children of central Sudan ethnicity

Prevalência de Hipovitaminose A em puérperas da Maternidade Escola Januário Cicco - Natal/RN / Prevalence of hypovitaminosis A in puerperal women at the University Maternity Januário Cicco – Natal, RN

As mães sociais que cuidam de crianças e adolescentes de abrigos filantrópicos de São Paulo, influenciam a elaboração dos cardápios e o modo de conduzir as refeições, de acordo com sua formação e cultura. Conhecer alguns aspectos sociais da alimentação desse grupo foi o objetivo deste trabalho. Foram feitas entrevistas com onze mães sociais e três diretoras de abrigos, analisadas por meio da metodologia do Discurso do Sujeito Coletivo. O estudo resultou em 32 categorias de discursos, por meio dos quais foram verificados valores e hábitos presentes nas refeições, que devem ser levados em conta quando se pretende desenvolver orientações e treinamentos na área da alimentação para esse público. Destaca-se a preocupação das mães com rituais familiares: comer “todos juntos ao redor da mesa” e manter silêncio durante as refeições são práticas impostas pela maioria das mães. A tarefa de servir os pratos praticamente é assumida pela mãe, não dando muitas oportunidades para as crianças aprenderem a se servir e escolher sozinhas os alimentos. O ensino de boas maneiras à mesa é uma preocupação diária e constante das mães, que não querem passar vergonha pelos maus modos das crianças, que precisam aprender a se comportar “lá fora”. Crianças, adolescentes e mães sociais de abrigos constituem uma alternativa de família, com dinâmicas e soluções próprias. As idéias centrais extraídas das entrevistas apontam um perfil dessas mães. Conhecer como pensam e sentem a respeito da alimentação é essencial para o aprimoramento da qualidade das refeições por meio de orientações e formação apropriadas

Deficiencia de vitaminas y minerales en México. Una revisión crítica del estado de la información: II. Deficiencia de vitaminas / Vitamins and minerals deficiency. A state of the art:II. Vitamin deficiency

Se realizó un análisis de los estudios que se han publicado desde 1950 a la fecha en relación con la deficiencia de vitaminas en México. Se encontraron 54 trabajos publicados, a partir de los cuales se concluye: a) los estudios epidemiológicos de ingestión de nutrimentos en diferentes regiones del país muestran que existe una ingestión deficiente de ácido ascórbico ( 40 a 70 porciento de la cantidad recomendada), riboflavina (25 a 60 por ciento) y retinol (20 a 72 por ciento) y, en menor grado de niacina; b) aproximadamente 10 por ciento de los niños mexicanos en zonas rurales presentan valores deficientes de retinol en plasma (< 100ng/ml) y de 25 a 30 por ciento presentan valores bajos de retinol (100-200 ng/ml); estas prevalencias se reducen notablemente en niños con mayor nivel socioeconómico; c) existen algunos estudios que muestran la existencia de deficiencias marginales de vitamina E, riboflavina y vitamina B-12 en poblaciones aparentemente sanas. Se requieren estudios epidemiológicos que identifiquen la magnitud de estas deficiencias y quizá las de otras vitaminas, así como sus consecuencias en la salud y funcionalidad de la problación mexicana

We carried out a review of the studies related to vitamin deficiencies in the Mexican population published since 1950. Forty four studies were published from which we can conclude that: a) dietary intake data suggest that ascorbic acid, riboflavin and retinol intake are deficient: reported intakes were 40-70%, 35-64% and 20-72% of the recommended daily amounts respectively; niacin intake was also deficient in some studies; b) about 10% of Mexican children in rural areas had deficient values of plasma retinol (<100 ng/ml) and about 25 to 30% had low values (100-200 ng/ml); this prevalence is reduced in children with a higher socioeconomic level; c) some studies were found that show the existence of marginal deficiencies of vitamin E, riboflavin and vitamin B12 in apparently healthy populations. Further studies are required to identify the magnitude of these and perhaps other vitamin deficiencies and their potential effects on the health and function of the Mexican population.

Ingesta alimentaria de escolares rurales de la región metropolitana de Chile: un estudio comparativo: 1989 / Food consumption among rural schoolchildren from the metropolitan area of Chile: a comparative study: 1989

A comparative study of dietary intake of a representative sample of 651 rural school children from Chile's Metropolitan Region was carried out between two periods: 1986-1987 and 1989. Standard procedures for 24 hr dietary recall individual interviews were used to collect data. The percentage of adequacy of energy and protein intake was calculated based on FAO/OMS/UNU (1985), and vitamins and minerals according to National Research Council Recommended Dietary Allowances. Socioeconomic status (SES) was measured through Graffar's Modified Method. Statistical procedures included chi-square test, analysis of variance and Student t test. Between 1986-1987 and 1989 not significant difference was found for dietary intake, despite the socioeconomic conditions had improved. Most part of the sample satisfied energy and protein requirements, but approximately 1/3 of the sample presented a low energy intake; the same was observed for protein intake. Protein contributed 12.0% of the dietary energy, fat 23.0% and carbohydrates 65.0%. Animal and vegetable protein intake was found in the proportion 4:6. Dietary intake significantly differed according to age and SES, and deficiencies in calcium, vitamin A, riboflavin and niacin intake were detected in both sexes. These results could be useful for food and nutrition planning related to school feeding programs and nutrition education
