Moraes LI, Nicola TC, Jesus JS, Alves ER, Giovaninni NP, Marcato DG, Sampaio JD, Fuly JT, Costalonga EF - Arq. Bras. Cardiol. (2013)

Bottom Line: It was identified a strong association between the presence of overweight and the occurrence of high blood pressure, regardless of the test used (p<0.001).The test showing the highest sensitivity in predicting elevated BP was the Conde e Monteiro (44%), while the highest specificity (94%) and greater overall accuracy (63%), was the CDC criterion.The prevalence of overweight in Brazilian children is higher when using the classification criterion of Conde e Monteiro, and lower when the criterion used is IOTF.

ABSTRACT

Background: Several authors have correlated the increase of cardiovascular risk with the nutritional status, however there are different criteria for the classification of overweight and obesity in children.

Objectives: To evaluate the performance of three nutritional classification criteria in children, as definers of the presence of obesity and predictors of high blood pressure in schoolchildren.

Methods: Eight hundred and seventeen children ranging 6 to 13 years old, enrolled in public schools in the municipality of Vila Velha (ES) were submitted to anthropometric evaluation and blood pressure measurement. The classification of the nutritional status was established by two international criteria (CDC/NCHS 2000 and IOTF 2000) and one Brazilian criterion (Conde e Monteiro 2006).

Results: The prevalence of overweight was higher when the criterion of Conde e Monteiro (27%) was used, and inferior by the IOTF (15%) criteria. High blood pressure was observed in 7.3% of children. It was identified a strong association between the presence of overweight and the occurrence of high blood pressure, regardless of the test used (p<0.001). The test showing the highest sensitivity in predicting elevated BP was the Conde e Monteiro (44%), while the highest specificity (94%) and greater overall accuracy (63%), was the CDC criterion.

Conclusions: The prevalence of overweight in Brazilian children is higher when using the classification criterion of Conde e Monteiro, and lower when the criterion used is IOTF. The Brazilian classification criterion proved to be the most sensitive predictor of high BP risk in this sample.

Mentions: Regarding the general characteristics of the sample studied, it was obtained homogeneityin relation to sex, being represented by 51% (n = 417) of boys and 49% girls (n = 400).The mean age was 8.8 ± 1.6 years. Depending on the criteria used to evaluate nutritionalstatus, the percentage of eutrophic children ranged between 67% and 73%, and thepercentage of children presenting excess weight (overweight or obese), between 21% and27% (Figure 1).
