ABSTRACT
The variables were analyzed longitudinal anthropometric that measures the dimension and corporal composition of students of the first Stage of Basic Education of the Educative of the Grand Colombia Educational Unit. The analyzed variables they were: Age, Sex, Weight (W), Height (H), Circumference (AC), Index of Corporal Mass (CMI), cutaneous fold: Triceps (TrP) and Subescapular (SeP), Muscular Area (AM) and fatty Area (FA). 141 children were evaluated with age of beginning to the 6 and 8 years with pursuit of four annual measurements. It was applied a sampling stratified random with equal afijación. The scholars were measured following the techniques established and accepted internationally he stops such aim. One settled down as point of cut between percentiles 10 and 90. Used values of reference were those of the Cross-sectional Study of Caracas (ETC) and of the Longitudinal Study of Caracas (CSCMA). In the analysis longitudinal it was applied to the method "Tracking" and the statistical Kappa in order to determine the channel of growth in each boy and the speed was evaluated of growth of the students. In the four evaluated groups, W and the H have biggest trackng indices with respect to the others variables. The tracking index was constant (Kappa = 0.25) for all the variables and all the groups, opposite situation to the global Kappa, as it was located in the category of "G ood" (Kappa = 0.40 to 0.75) for the W and H in all the groups of evaluated scholars. The AC in the girls of both series of ages and in CMI, only in the girls with follow-up at 6 years canalization is observed "Good". One stayed in "Low" (Kappa = < 0,40) in all the sample of students the TrP, SeP, MA and FA. Variables of corporal dimension register good canalization, unlike the variables that measure corporal composition, which are located in loss canalization. The girls of both groups register greater speed of growth in Weight that the boys. The values of the average in the W and H, in evaluated students, end speed (S3) he is superior to initial speed (S1), therefore, the speed of growth it increases with the age. The maximum speed of growth is registered in the S3. In the evaluated students the variables that better they canalize are those of corporal dimension, is inferred, that corresponds to a growth pattern hoped.

Se explora la evaluación del hipocinetismo como factor de riesgo para la salud. A tal fin fueron analizados los hábitos de actividad física y el nivel de riesgo cardiovascular, en 314 estudiantes no atletas de la Universidad Central de Venezuela con edades entre 17 y 29 a¤os, mediante la aplicación del Cuestionario Internacional de Actividad Física-IPAQ (2004) y un cuestionario de Hoeger y Hoeger (2002) para la estimación del riesgo cardiovascular. Los resultados indicaron que globalmente 31,53 por ciento de los sujetos tenían un nivel de actividad física que se relaciona con hipocinetismo. Se evidenció que las jóvenes estudiadas mostraron mayores niveles de riesgo cardiovascular. Se identificaron asociaciones entre las variables género y la categoría de riesgo cardiovascular, asícomo entre esta última y los niveles de actividad física, apuntando a que el hipocinetismo representa un factor de riesgo adicional en el desarrollo de enfermedades crónicas no transmisibles en los ucevistas evaluados.

In the Caracas Longitudinal Study, the canalization of 24 girls that started follow-up at age 4, 43 at age 8, and 32 at age 12 in: height (H), weight (W), Body Mass Index (BMI), cholesterol (CHOL), triglycerides (TG) and glucose (GL), was studied using Schneiderman n Tracking Index (TI) and age to age correlations. TI presented a gradient H > W > BMI > CHOL and lower in TG and GL. TI of all variables diminished increased with age and in BMI and CHOL. Age to age correlations were significant at all ages in H, W. and BMI and higher in CHOL (p < 0.01) compared to TG and GL. The significant tracking of H, W, BMI and lipids, specially CHOL, is relevant in prevention of non-communicable chronic diseases.
