Presión arterial en preescolares de la localidad de Usaquén en Bogotá

Abstract

Background: Hypertension is a public health problem in both industrialized and developing. Its prevalence in children is increasing so it is important to determine it in preschool children locally. Objective: Determine the prevalence of hypertension in children three to five years in a cohort of 14 children's homes ICBF in the town of Usaquén in Bogota. Material and Methods: We performed a cross-sectional analytical study, using the database of a randomized controlled trial in 200913, we evaluated the blood pressure levels according to sex, age, height and BMI correlated with a confidence level of 95% and accuracy of 1%. We calculated the mean, standard deviation, percentiles and prevalence. Result: We obtained a sample of 1035 cases found a prevalence of 4.5% of systolic BP, diastolic 10.4%, both in stage I; taking into account both systolic and diastolic was 11.6% in stage I. We determined the values of systolic and diastolic blood pressure into quartiles according to age, sex and height. The correlation coefficient between BMI and levels of systolic and diastolic blood pressure were 0.0992 and 0.0362 respectively. Conclusion: The overall prevalence of hypertension was 11.6%, predominantly stage I diastolic preschoolers. No correlation was found between BMI and figures for systolic and diastolic blood pressure.
