The association between high blood pressure, physical fitness and fatness in adolescents.

INTRODUCTION: Hypertension is a health problem that is of national importance. It is a major risk factor for the occurrence of atherosclerosis and cardiovascular, cerebrovascular and renal diseases that are leading or among the leading causes of mortality and morbidity as in ours, as in the most developed and less developed countries. OBJECTIVE: The purpose of this study is to analyze the relation of cardiorespiratory fitness and obesity, blood pressure and hypertension for adolescents. MATERIAL AND METHODS: The research was realized on a sample of 4,051 boys and girls at the age of 11 to 14 years. Cardiorespiratory fitness was assessed by using a three minute step test, while the percentage of body fat was determined by bioelectrical impedance method. Blood pressure was measured three times at intervals of 60 seconds, and the result was the median value of the three measurements. The measurements were performed in a separate room with optimum ambient conditions. The relation between hypertension, cardiorespiratory fitness and fat was determined by correlation and multi-nominal logistic regressive analysis. RESULTS: Boys had higher systolic pressure and lower diastolic pressure compared to girls. The low level of cardiorespiratory fitness and high percentage of body fat were independently associated with an increased risk of blood pressure and hypertension for both boys and girls. The interaction was established between the percentage of body fat and fitness. CONCLUSION: The results should be taken into account for building strategies and recommendations for improvement of lifestyle and health for adolescents.

Introducción: la hipertensión es un problema de la salud y es de importancia nacional. Es un factor de riesgo importante para la aparición de la aterosclerosis y enfermedades cardiovasculares, cerebrovasculares y enfermedades renales que están liderando o están entre las principales causas de mortalidad y la morbilidad como en la nuestra, también en los países más desarrollados y menos desarrollados. Objetivo: el objetivo de este estudio es analizar la relación de la aptitud cardiorrespiratoria y la obesidad, la presión arterial y la hipertensión en los adolescentes. Material y métodos: la investigación se realizó sobre una muestra de 4.501 niños y niñas de 11 a 14 años. La capacidad cardiorrespiratoria se evalúo con el uso de una prueba de paso que dura tres minutos, mientras que el porcentaje de grasa corporal se determinó con un método de impedancia bioeléctrica. La presión arterial se midió tres veces a intervalos de 60 segundos. El resultado fue el valor medio de las tres mediciones. Las mediciones se realizaron en una habitación separada con condiciones ambientales óptimas. La relación entre la hipertensión, la aptitud cardiorrespiratoria y la grasa se determina con un análisis de correlación y multinominal regresión logística. Resultados: los niños tenían una mayor presión sistólica y diastólica que las niñas. El nivel bajo de aptitud cardiorrespiratoria y el porcentaje alto de grasa corporal se asociaron independientemente con un mayor riesgo de hipertensión arterial e hipertensión para niños y niñas. La interacción se establece entre el porcentaje de grasa corporal y la forma física. Conclusión: los resultados obtenidos se deben tener en cuenta para la construcción de estrategias y recomendaciones para la mejora del estilo de vida y la salud de los adolescentes (AU)
