Background: Excess of body fat, often resulting from lifestyle habits, increases the risk of cardiovascular disease (CVD) and the prevalence of deaths from chronic non-communicable
diseases (NCDs). Reduction in body weight may normalize blood pressure levels, making unnecessary the use of medications for hypertensive individuals. Worldwide prevalence of hypertension in
adolescents (3-11%) bolster the need for multiprofissional programs of obesity treatment with a focus on physical activity, psychological and nutritional intervention, which may contribute to the
reduction of risk factors for CVD. Aiming to understand the relationship between blood pressure and anthropometric variables, body composition and physical fitness in adolescents with overweight, it
was decided to investigate the influence of body mass, body mass index (BMI), waist circumference (WC), relative fat mass (RFM) and VO2max over blood pressure (BP) of beginner adolescents in a
Multiprofessional Program of Obesity Treatment (MPOT).
Methods: This is a cross-sectional study, with 27 adolescents aged 14 to 17 years old committed in a MPOT between 2014 and 2015, which were analyzed the anthropometric data (body
mass, BMI and WC), body composition (RFM), physical fitness (cardiorespiratory fitness - VO2 max) and blood preassure (BP). There were used the cutoffs from The International Diabetes Federation
consensus definition of the metabolic syndrome in children and adolescents for blood pressure classification in the normal and altered. It was held descriptive statistics (mean, standard deviation and
frequency distribution) and inferential (t-student test and Mann Whitney U test) to observe the results.
Results: Comparing the body mass, BMI, WC, RFM and VO2max among adolescents with normal blood pressure (NBP) and altered (ABP), it was observed that the group with ABP showed the
worst results with significant differences for body mass, BMI and WC. In addition, there was a major change in prevalence of blood pressure among adolescent males, severely obese, abnormal WC, higher
RFM and lesser VO2max.
Conclusions: Body mass, BMI and WC directly influence blood pressure among adolescents, highlighting the need for obesity prevention and treatment based on multidisciplinary programs
for this population, since excess of weight is recognized as a major determinant of blood pressure elevation both in adults and in children and adolescents.
