Association between time spent in sedentary, moderate to vigorous physical activity, body mass index, cardiorespiratory fitness and blood pressure.

Abstract

BACKGROUND: Elevated blood pressure (BP) has been reported in young people and seems to be associated with body mass index (BMI) and reduced physical activity (PA). AIM: This study sought to analyse the association of BP with BMI, PA intensity patterns and cardiorespiratory fitness (CRF) in youth. SUBJECTS AND METHODS: A cross-sectional study was carried out including 66 boys (13.91+/-1.76) and 97 girls (14.02+/-1.71). Anthropometric characteristics, CRF and BP were assessed during school time and accelerometers were utilized to determine intensity of PA. RESULTS: The linear regression model, adjusted for age, sex and height, showed that higher values of BMI were associated (p
