[Body mass index to the cardiovascular disease risk screening in infancy].

OBJECTIVE To purpose news body mass index (BMI) cut offs to 7 to 12 years old scholars. SUBJECTS AND METHODS 1.413 scholars of 7 to 12 years old selected of aleatory way. Were measured the BMI, total cholesterol (TC), and systolic (SBP) and diastolic blood pressure (DBP). To the date analyze were used the receiver operating characteristic curve (ROC curve) and the bivariate analyze. RESULTS The BMI cut offs proposed at this study show adequate capacity to identify true positive and negative to the cardiovascular diseases (CVD) risk factors presence. Besides, these cut offs show higher and more balanced sensibility and specificity values than other cut offs proposals. CONCLUSIONS The BMI proposed at this study configure with as the more adequate alternative to the screening for the scholars with increased chances to carry DCV risk factors.
