RESUMO
Este estudio fue desarrollado con la finalidad de formular una ecuación de predicción de % de masa adiposa en valores antropométricos, a partir, de los valores predeterminados a través del instrumento de bioimpedancia TANITA. Esto basado en la premisa de que cada día ha aumentado la importancia sobre la estimación de la masa adiposa a nivel clínico, por lo cual se evaluó una población de 28 sujetos cuyo rango de edad fluctúa entre los 20-28 años, pertenecientes a la Escuela de Caballería Blindada de la ciudad de Quillota. Se realizaron las mediciones pertinentes para la estimación de masa adiposa a través de la bioimpedancia y la antropometría, cuyos resultados arrojaron diferencias significativas entre ambos métodos, obteniendo un coeficiente de correlación de Pearson de 0,34. Esto nos indica que al evaluar los criterios de homocedasticidad, linealidad, para generar una ecuación de estimación, no sería posible...
This case was developed with the objective of makes a prediction equation of adipose mass percent in values anthropometric, to star off the predetermined slant of instruments of impedance bioelectric TANITA. This is based in the premise that every day the importance of estimation about the fat mass in a clinic level, it is getting bigger and bigger, for this reason a population of twenty eight people with age range fluctuate among twenty to twenty eight was evaluated, they were part of "Escuela de Caballería Blindada" in the city of Quillota. The Pertinent measurements for the estimation of fatty mass were realized through of impedance bioelectric and anthropometry, the results made big differences between both methods, obtaining an index of correlation coefficient a 0.13 and a person correlation of 0.34. This suggests that possible creation does not accomplish with the criteria homescedasticity, in brief, this is unsafe...

Las alteraciones posturales tales como hiperlordosis, aumento de la cifosis, cifolordosis y escoliosis en columna, producen complicaciones a nivel músculo-esquelético y articular. Debido a esto, es que en el último tiempo ha aumentado el número de atenciones kinésicas por patologías de la columna lumbar, he aquí la importancia de un test clínico que cuente con la confiabilidad necesaria para determinar la curvatura lumbar. El objetivo de este estudio es determinar si existen diferencias en los resultados entre los dos métodos utilizados para medir la curva lumbar: el test clínico de las flechas sagitales y el ángulo de la columna lumbar mediante radiografías. En una muestra de 32 pacientes de edad promedio 44,93 (+/- 12,67 años) evaluados en el Servicio de Kinesiología del Centro Médico Megasalud de Viña del Mar entre los meses de Marzo y Agosto del 2008. El procedimiento utilizado fue el examen clínico, en el cual se usó una plomada que va desde C7, pasando por la línea ínterglútea. En el plano sagital se mide la curvatura lumbar a nivel de L3. Para la medición del ángulo de la curvatura lumbar se utilizó una radiografía proyección lateral en la cual se proyectan las mesetas superior de L1 e inferior de L5 para la conformación del ángulo lumbar y su posterior medición. El resultado obtenido por medio del examen clínico entre el test de las flechas sagitales y las radiografías del ángulo de la lordosis lumbar para un índice de concordancia de Kappa, fue mayor o igual a un 95 por ciento. De esta manera, se obtuvo que el test de las flechas sagitales es una herramienta válida para la pesquisa de patologías lumbares, al igual que la radiografía, con una marcada diferencia en el costo económico entre ambas.
The altered posture, such as hiperlordosis, increase in kyphosis, and scoliosis in cifolordosis column complications occur at the muscular, skeletal and articulate. Because of this, is that in recent times to increase the number of benefits for kinesics pathologies of the lumbar spine, and here the importance of a clinical test that has the confidence necessary to determine lumbar curvature. The objective of the study seeks to determine whether there are differences in outcomes between the two methods used to measure the lumbar curve, the test of the arrows sagitales and the angle of the lumbar spine using x-rays in patients greater than or equal to 21 years, as assessed the service kinesiology of Centro Médico Megasalud of Viña del Mar, between the months of March and August 2008. The procedure used was by means of physical examination, which uses a plumb line that runs from C7 through inter gluteal line in the sagittal plane was measured at the lumbar curvature of L3 and compared with the measurement of the angle curvature of the lumbar measured by radiographic position in bipedal in a side view in 32 adults, measures of kinesiology at the service of the Medical Center Megasalud of Viña del Mar, Chile. The result obtained by means of physical examination between the test of the arrows sagitales versus the angle of the lumbar lordosis measured by X-rays, reached a record of correlation between the two diagnostic tests greater than or equal to 95 percent. In conclusion we can say that the test of the arrows sagitales is a valid tool for the investigation of lumbar pathologies, like radiography, with a marked difference in cost between the two.

The objective of this study was to assess the relative impact of undernutrition during the first year of life on brain development, intellectual quotient (IQ), and scholastic achievement (SA) of poor Chilean high-school graduates (mean age = 18.3 +/- 0.9 y). A comparative study of two groups of high-school graduates from a low socioeconomic stratum was carried out. The undernourished group (n = 16), who had suffered from severe undernutrition during the first year of life, was compared with the non-undernourished group (n = 16). The final sample consisted of 32 right-handed high-school graduate students born at term who had no history of alcoholism or symptoms of brain damage, epilepsy, or heart disease and whose mothers had no history of smoking, alcoholism, or drug intake before and during pregnancy. Socioeconomic status was measured by using Graffar's modified method. Birth weight was used as the prenatal nutritional status index, and postnatal nutritional status was assessed by the body mass index, Z score for head circumference, and brachial anthropometry. IQ was determined with the Wechsler Intelligence Scale for Adults, and SA was determined with test in language and mathematics with the academic aptitude test. Brain development was evaluated by magnetic resonance imaging. Statistical analysis included variance tests, Scheffe's test for comparison of means, correlation, and multiple regression. Maternal schooling, brain volume, and undernutrition were the independent variables, with the greatest explanatory power in IQ variance (r(2) = 0.714). Only IQ explained SA variance (r(2) = 0.860); IQ, corpus callosum length, anteroposterior diameter, and maternal schooling were the independent variables, with the greatest explanatory power in the academic aptitude test variance (r(2) = 0.949). Results show that the long-term effects of malnutrition at an early age may affect brain development, IQ, and SA in school-age children. These findings are useful for nutrition and educational planning.
