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

Abstract

The association between high blood pressure, physical fi tness and fatness in adolescents Resumen 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. Key words:Blood pressure. Physical fi tness. Fatness. Adolescent. AbstractIntroduction: 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 fi tness 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 fi tness 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 fi tness and fat was determined by correlation and multi-nom...

Association between Adherence to the Mediterranean Diet and Physical Fitness with Body Composition Parameters in 1717 European Adolescents: The AdolesHealth Study

“…Moreover, abdominal adiposity in combination with a poor PF are directly associated with serious diseases [77,78]. The association between body composition parameters (waist circumference, percentage of body fat, and BMI) and performance in numerous fitness tests has been extensively studied in Europe [79] and non-European countries [80,81], thus determining the need for preventive work and the monitoring of the health status of adolescents. If we examine the results of the tests of the AFB, a better performance can be observed among those participants with N-O waist , N-O fat , and N-O weight in the long jump, speed/agility, and cardiorespiratory resistance tests.…”

Anti-Obesity Effects of Medicinal and Edible Mushrooms

“…Medications regularly require long administration periods as many individuals regain their lost weight when medication is suspended. The suspension of medication use by individuals is typically due to their major side effects, cost, and a potential lack of insurance coverage [ 52 ].…”

Physical Activity Practice and Healthy Lifestyles Related to Resting Heart Rate in Health Sciences First-Year Students

“…Most of the findings related to RHR come from investigations aimed to establish a relationship between RHR and risk factors for cardiovascular diseases, such as blood pressure and inflammatory markers. The literature has reported that adolescents and young adults with better performance in physical fitness tests have lower odds of high blood pressure, hypercholesterolemia, and cardiovascular dysfunction, as well as lower RHR 23,24 . The healthrelated issues have positive changes in RHR.…”
