Abstract

Background and objective. Koch et al., reported that the Waist/Hip Index more accurately predicts cardiovascular risk factors and mortality. Huaman et al., reported that the Waist/Height Index can be used as a diagnostic test for metabolic syndrome, since it has a high significant value. To determine whether two anthropometric indices have sufficient prognostic efficiency or moderate prognostic efficiency by combining sensitivity and specificity using positive and negative likelihood ratios in a single expression. Material and methods. Quantitative epistemological approach. Descriptive observational epidemiological study without directionality and with prospective temporality. Three husband adult patients of both genders who attended the Integral Hospital "Jose Maria Morelos" were studied. As a reference test or Gold Standard was used the Lorentz Equation as a reference test. Results. The results for the positive likelihood ratios corresponded to 13.41 and 1.72 for the anthropometric indices Waist/Height Index and Waist/Hip Index, respectively. The results for the negative likelihood ratios corresponded, respectively, to 0.07 and 0.48 for the anthropometric indices Waist/Height Index and Waist/Hip Index. Conclusions. The best anthropometric index for the diagnosis of overweight and obesity pathological nutritional situations corresponds to the Waist/Height Index, since the results of the positive and negative likelihood ratios report sufficient prognostic efficiencies. On the other hand, the results of the positive and negative likelihood ratios report, respectively, negligible prognostic efficiency and poor prognostic efficiency for the Waist/Hip Index.
