The accuracy of national body fat cutoff levels in the prediction of elevated blood pressure among Brazilian male adolescents.
OBJECTIVE
To assess viability of the development of percentage body fat cutoffs based on blood pressure values in Brazilian adolescents.


METHODS
A cross-sectional study was conducted with a sample of 358 male subjects from 8 to 18 years old. Blood pressure was measured by the oscilometric method, and body composition was measured by dual-energy X-ray absorptiometry (DXA).


RESULTS
For the identification of elevated blood pressure, these nationally developed body fat cutoffs presented relative accuracy. The cutoffs were significantly associated with elevated blood pressure [odds ratio = 5.91 (95% confidence interval: 3.54-9.86)].


CONCLUSIONS
Development of national body fat cutoffs is viable, because presence of high accuracy is an indication of elevated blood pressure.
