ARNAIZ, Pilar et al. Waist-Height ratio as a predictor if cardio-metabolic risk in children. Rev Chil Cardiol [online]. 2010, vol.29, n.3, pp.281-288. ISSN 0718-8560.  http://dx.doi.org/10.4067/S0718-85602010000300001.

Background: Among children both general and visceral obesity are associated with increased cardio-metabolic risk. The increasing prevalence of the metabolic syndrome (MS) in children and adolescents increases cardiovascular risk. Studies of new clinical markers which can easily and accurately predict MS in children and adolescents are needed. Aim: To compare zBMI and waist to height ratio (WHR) as predictors of MS in Chilean children. Method: We performed a crossectional study of 618 schoolchildren, age 11 ± 2 years, 52 % females, 190 eutrophic, 174 overweight, 254 obese, from middle and low social economic strata from the Santiago urban área. We determined weight, height, waist circumference, blood pressure and fasting lipids and glycemia. MS diagnosis was based on the presence of > 3 Cook criteria. MS was modeled in function of WHR and z score BMI, through logistic regression models. ROC curves were used to compare zBMI and WHR as predictors of MS. The cutoff point by YOUDEN índex was used. Results: The prevalence of MS was 15%. Mean zBMI was +1.22 ± 0.90 and WHR 0.52 ± 0.07. Cutoff point for MS were: WHR 0,55 (sensitivity 72%, specificity 70%)andzBMI: 1.76 (sensitivity 71%, specificity 74%). Conclusions: Both WHR and zBMI similarly predicted cardio metabolic risk in children and adolescents. The greater feasibility of calculating WHR makes it a good tool for defining risk in this group. A cutoff point >0.55 might be a good predictor of MS in children and adolescents .
