Cardiorespiratory Fitness, Surplus Weight and High Blood Pressure in Adolescents

Objective: To analyze the association among cardiorespiratory fitness, surplus weight and high blood pressure in school children from the private sector. Methods: 205 young students with age ranging from 11 to 14 years old It were recruited to participate in the study. Body mass, stature, systolic and diastolic blood pressure were measured and a running test was applied. The statistic procedures were composed of medians, interquartile interval, chi-square test and Poisson regression. Results: The prevalence of surplus weight was of 40.6% for the male sex and 28.4% for the female sex (p= 0.091), and the occurrence of high blood pressure was of 20.8% for the male sex and 13.8% for the female sex (p= 0.247). There was association between surplus weight and high blood pressure (PR= 3.92 [1.54-9.98]); however, no association was found for surplus weight and the running test (PR= 0.60 [0.23-1.56]). Conclusion: It was concluded that the association between cardiorespiratory fitness is mediated by the nutritional status.
