Aptidão cardiorrespiratória, excesso de peso e pressão arterial elevada em adolescentes / Cardiorespiratory fitness, surplus weight and high blood pressure in adolescents

RESUMO

OBJETIVO: Analisar a associa��o entre aptid�o cardiorrespirat�ria, excesso de peso e press�o arterial elevada em repouso entre alunos da rede privada de ensino. M�TODOS: Participaram do estudo 205 jovens de ambos os sexos com idades entre 11 e 14 anos. Foram aferidos valores de massa corporal, estatura, press�o arterial sist�lica, diast�lica e teste de corrida. A an�lise estat�stica foi composta de valores de m�dia,desvio-padr�o, teste do Qui-quadrado e regress�o de Poisson. RESULTADOS: A preval�ncia de excesso de peso foi de 40,6 por cento para o sexo masculino e 28,4 por cento para o feminino (p = 0,091), e a press�o arterial elevada em repouso foi de 20,8 por cento para o sexo masculino e 13,8 por cento para o feminino (p = 0,247). O excesso de peso apresentou associa��o significante com a press�o arterial elevada (RP = 3,92 [1,54-9,98]); entretanto, o resultado no teste de corrida, n�o (RP = 0,60 [0,23-1,56]). CONCLUS�O: Conclui-se que a associa��o entre aptid�o cardiorrespirat�ria e press�o arterial elevada parece ser mediada pelo estado nutricional.

ABSTRACT

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 percent for the male sex and 28.4 percent for the female sex (p= 0.091), and the occurrence of high blood pressure was of 20.8 percent for the male sex and 13.8 percent 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.
