RESUMO

INTRODUCTION: Anemia is a public health problem worldwide and is most prevalent in preschool children, for whom it is the most frequent cause of nutritional deficits. In turn, iron deficiency is the main cause of anemia, affecting 43% of children globally. Previous studies in Cuba show rates of iron deficiency in preschool children between 38.6% and 57.6%, higher in infants (71.2% to 81.1%). WHO recommends using serum ferritin as an indicator of iron deficiency accompanied by acute (C-reactive protein) and chronic (a1-acid glycoprotein) inflammation biomarkers. OBJECTIVE: Assess how inflammation affects measuring and reporting of iron-deficiency anemia rates in Cuban preschool children. METHODS: Data were obtained from serum samples contained in the National Anemia and Iron Deficiency Survey, and included presumably healthy preschool Cuban children (aged 6-59 months). Serum samples were collected from 1375 children from randomly selected provinces in 4 regions of the country from 2014 through 2018. We examined the association between ferritin and two inflammatory biomarkers: C-reactive protein and a1-acid glycoprotein. Individual inflammation-adjusted ferritin concentrations were calculated using four approaches: 1) a higher ferritin cut-off point (⟨30 g/L); 2) exclusion of subjects showing inflammation (C-reactive protein ⟩5 mg/L or a1-acid glycoprotein ⟩1 g/L); 3) mathematical correction factor based on C-reactive protein or a1-acid glycoprotein; and 4) correction by regression with the method proposed by the Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia Group. We estimated confidence intervals of differences between unadjusted prevalence and prevalence adjusted for inflammation by each method. RESULTS: The proportion of children with inflammation according to C-reactive protein concentrations >5 mg/L was lower (11.1%, 153/1375) than the proportion measured according to the concentrations of a1-acid glycoprotein, at >1 g/L (30.8%, 424/1375). The percentage of children with high concentrations of at least one of the aforementioned biomarkers was 32.7% (450/1375). Thus, each correction method increased the observed prevalence of iron deficiency compared to unadjusted estimates (23%, 316/1375). This increase was more pronounced when using the internal regression correction method (based only on C-reactive protein) or the method based on a higher cut-off point. Adjustment using all four methods changed estimated iron deficiency prevalence, increasing it from 0.1% to 8.8%, compared to unadjusted values. CONCLUSIONS: One-third of preschool children had biomarkers indicating elevated inflammation levels. Without adjusting for inflammation, iron deficiency prevalence was underestimated. The significant disparity between unadjusted and inflammation-adjusted ferritin when using some approaches highlights the importance of selecting the right approach for accurate, corrected measurement. The internal regression correction approach is appropriate for epidemiological studies because it takes into account inflammation severity. However, other models should be explored that account for inflammation and also provide better adjusted ferritin concentrations.

RESUMO

Las diferencias morfológicas entre los bailarines de ballet, danza moderna y folklórica están bien confirmadas en los criterios empíricos de evaluación técnica de los maestros de especialidad. El propósito de esta investigación es determinar si las características de la forma corporal de los bailarines elites de ballet son específicas de esta manifes- tación artística. Se estudiaron antropométricamente bai- larines de las compañías Ballet Nacional, Danza Nacional y Folclórico Nacional de Cuba. Siguiendo el criterio de selección de los maestros, en cuanto a figura y desempeño técnico artístico, se midieron los mejores bailarines de cada compañía; edades entre 18 y 40 años. Para determinar la forma corporal, se aplicó un protocolo antropométrico de 10 mediciones y se utilizó el método del somatotipo de Heath-Carter. El somatotipo de las bailarinas de ballet, Ecto-Mesomórfico en promedio, fue significativamente diferente al de las bailarinas de danza folklórica. El soma- totipo de los bailarines, Meso-Ectomórfico en promedio, fue similar estadísticamente al de las otras especialidades de danza. Las categorías somatotípicas más representadas para las bailarinas de ballet fueron la Ectomórfico Balan- ceado (50%) y la Ecto-Mesomórfico (40%); en el sexo mas- culino fue predominante la categoría Meso-Ectomórfico (90%). Los bailarines de ballet de ambos sexos presentaron distribuciones de frecuencias somatotípicas en menos categorías y significativamente diferentes que las de danza moderna y folklórica. La forma corporal fue específica para los bailarines elites de ballet Se reafirmaron los criterios empíricos que sustentan las diferencias morfológicas entre los tipos de bailarines para la estimación antropométrica de la forma corporal (AU)


The morphological differences among ballet, modern and folkloric dancers are well confirmed in the empirical criterions of technical evaluation for specialty teachers. The purpose of this research is assessing if the human shape of professional ballet dancers are specific for this artistic spe- cialist. It was anthropometrical studied dancers of National Ballet, National Dance and National Folkloric companies from Cuba. It was measured the best dancers, ages between 18 and 40 years old, following the selection criterions of expert teachers about figure and technical-artistic perfor- mance. An anthropometric protocol of 10 measurements was applied in order to determine the human shape, using the Heath-Carter somatotype method. The somatotype of female ballet dancers, Ecto-Mesomorfic on average, were significantly different that those of female folkloric dancers. The somatotype of male ballet dancers, Meso-Ectomorfic on average, were statically similar that those of others dan- cer specialties. The somatotypes of female ballet dancers were mainly distributed in 2 categories, Balanced Ectomor- fic (50%) and Meso-Ectomorfic (40%) while most of male dancers were classified like Ecto-Mesomorfic (90%). Both sexes of ballet dancer registered somatotypic frequencies distributions in few categories, significantly different, than modern and folkloric distributions. The human shape was specific for the elite ballet dancers. There were confirmed the empirical criterion of specialty teachers which support differences among kinds of dancers for the anthropometric estimation of human shape (AU)

RESUMO

Fundamentos: La tercera edad representa una etapa delciclo vital con vulnerabilidad del estado nutricional devitaminas y otros nutrientes. Con el objetivo de conocer elestado nutricional de la vitamina B1 se realizó un estudioen 165 adultos mayores no institucionalizados mayoresde 60 años del municipio Habana del Este.Métodos: La vitamina B1 fue ensayada mediante la técnicade determinación del efecto del TPP en la enzimaTranscetolasa eritrocitaria. La ingestión dietética fue evaluadaa través de una encuesta dietética cuantitativa porregistro de alimentos de 3 días en una submuestra de 47adultos mayores. El peso corporal y las distancias hombro-codo y rodilla-talón fueron medidos como estimadoresde la talla de los adultos mayores para evaluar el índicede masa corporal (IMC). El hábito de fumar, el consumode bebidas alcohólicas y el uso de suplementos vitamínicosfueron recogidos en una encuesta epidemiológicasocio-médica.Resultados: Aproximadamente el 35% de los individuosestudiados tenía niveles marginales y deficientes de vitaminaB1 y casi el 70% no cumplía el 70% de la cantidaddiaria recomendada de esta vitamina con la dieta. No seobservó correlación entre la ingestión dietética de vitaminaB1 y su indicador bioquímico. El 40% de los adultosmayores tenía sobrepeso corporal. El IMC fue significativamentesuperior en mujeres; el grupo mayor de 80 añostenía valores inferiores de IMC. No se encontró diferenciasignificativa del nivel de la vitamina en cuanto a sexo,edad, consumo de suplementos vitamínicos ó hábitostóxicos. Solo el 38% de los adultos mayores consumíanvitaminas como suplemento dietético.Conclusión: Se recomienda que debe ser mejorado elestado nutricional de esta vitamina en este grupo de poblacióna través de la ingestión de alimentos portadoresy el consumo de suplementos vitamínicos


Introduction: Aging is a stage of life with certainvulnerability of the nutritional status of vitamins and othernutrients. With the objective to know the nutritional statusof the vitamin B1 was carried out a study in 165 noninstitutionalisedelderly over 60 years of East Havanamunicipality, Cuba.Methods: Vitamin B1 was assayed by determination ofthe effect of the TPP in the enzyme erythrocite transcetolasa.Dietary intake was evaluated by a 3-day food diary in asubsample of 47 aged people. Body weight, shoulderelbowand knee-heel distances were measured to evaluatethe body mass index (BMI). Smoking habits, consumptionof alcoholic beverages and use of vitamin supplementswere registered in a questionnaire.Results: Approximately 35% of the studied individualshad marginal and deficient levels of vitamin B1 and almost70% did not fulfill 70% of the recommended daily intake.There was no correlation between the dietary intake ofvitamin B1 and its biochemical indicator. 40% of the elderlypeople was overweight. BMI was significantly higher inwomen; individuals older than 80 years had lowest BMIvalues. The level of the vitamin was not significantlydifferent for sex, age, consumption of vitamin supplementsor toxic habits. Only 38% of the elderly took vitamins asa diet supplement.Conclusion: It is recommended that the nutritional statusof this vitamin should be improved in this populationgroup through adequate food intake and the consumptionof vitamin supplements

RESUMO

El porcentaje de infestación por Helicobacter pylori (Hp), medido mediante inmunoensayo cromatográfico fue muy elevado en niños menores de 2 años de edad atendidos por diarreas crónicas en dos hospitales pediátricos, o total en niños aparentemente sanos de un municipio de Ciudad de La Habana. En una muestra seleccionada al azar casi la totalidad de ellos mostró anticuerpos para esta bacteria. Los niños afectados de diarreas crónicas manifestaron un mayor porcentaje de antecedentes patológicos personales o familiares de parasitismo, giardiasis, gastritis, úlcera, estomatitis, glositis y otras manifestaciones clínicas con posible relación causal con la infección por Hp. A pesar de la función favorecedora de la hipoclorhidria posinfección, la elevada infestación por Hp tanto en niños enfermos como sanos no permite establecer asociaciones entre diarrea e infección por esta bacteria. La presencia de anticuerpos no es indicativo de infección activa. El diagnóstico confirmatorio en niños de esa edad debe realizarse por métodos isotópicos
