Comparison of two methodologies used for determining metabolic syndrome in adult population

Abstract

Introduction: Metabolic syndrome is characterized by the simultaneous or sequential appearance of various metabolic and inflammatory changes at molecular, cellular or hemodynamic level associated with the presence of insulin resistance and dominant visceral adiposity. Different expert groups, including the International Diabetes Federation and the National Cholesterol Education Program, have tried to develop criteria for its diagnosis.

Objective: To establish diagnostic criteria concordance levels for metabolic syndrome.

Materials and methods: A total of 357 people were part of the study. We performed a descriptive analysis of qualitative variables, and laboratory and anthropometric measurement results to determine the prevalence of metabolic syndrome according to the International Diabetes Federation and National Cholesterol Education Program - ATP III definitions. We used kappa concordance and logistic regressionfor the comparison of methodologies.

Results: The prevalence of metabolic syndrome was 19.9% according to the International Diabetes Federation, and 10.4% using the National Cholesterol Education Program - ATP III. The estimate of agreement between the two diagnostic criteria of the International Diabetes Federation and the National Cholesterol Education Program - ATP III was fair (low) (κ=0.3997, CI 95% 0.28-0.52).

Conclusions: In the working population who participated in this study, the obtained prevalence of metabolic syndrome occurred at a higher rate using the International Diabetes Federation definition, being higher in men than in women. The use of diagnostic criteria for metabolic syndrome must take into account the study population as well as sex and age.
