Obesity is currently an extremely large health problem. It affects individuals of all ages, especially the pediatric population. The purpose of this study was to compare blood pressure (BP) in a sample of adolescent students with body fat measured by body mass index (BMI) and body fat percentage (BF%) to verify if an increased waist circumference (WC) is associated with cardiovascular risk. The subjects consisted of 214 females and 86 males between 12 and 17 yrs of age. Height, body mass, waist circumference, and skinfold measurements were used to estimate the percent of adipose tissue. The results showed that females classified with excessive weight and a WC percentile >90 displayed higher BP compared to females with normal weight and a WC percentile <10. However, among the males the results did not demonstrate a similar association between body fat levels (BMI and WC) and BP.
