Groups are determined based on the BMI values at baseline; a comparison between the levels at baseline and after PiPy; b Comparison between males and females.
BMI, body mass index; DBP, diastolicblood pressure; PiPy, Physical exercise Intervention Program in the Youth; SBP, systolic blood pressure.
