Concordance between five criteria of metabolic syndrome in teenagers from a Peruvian high andes region.

OBJECTIVE.: Motivation for the study. There are several criteria for metabolic syndrome in adolescents, each reporting different prevalence rates and not necessarily coinciding with each other. Main findings. We studied school children from the city of Cajamarca at 2750 meters above sea level. The five criteria for metabolic syndrome coincided in six of the 397 (1.5%) adolescents. The criteria generated prevalence rates ranging from 3.0% to 17.1%. The criteria with near perfect concordance were those from the American Heart Association criteria and those modified by Cook. Implications. The diagnosis of metabolic syndrome in adolescents is complex, even more so among those residing at high altitudes. . To determine the concordance between five diagnostic criteria for metabolic syndrome (MS) among teenagers from a Peruvian high Andes region. MATERIALS AND METHODS.: A cross-sectional study was carried out with secondary data from an intervention study in two public schools in 2019. We included 397 teenagers who lived in the city of Cajamarca, in the Andean region of Peru. We applied the criteria from the Adult Treatment Panel III (ATP-III) modified by Cook, the International Diabetes Federation (IDF), the American Heart Association (AHA), Ferranti, and the World Health Organization (WHO). The point prevalence and interval prevalence were estimated with the five criteria. The Kappa concordance coefficient with an 95% confidence interval (95%CI) was estimated. RESULTS.: The Ferranti criterion identified 17.1% (95%CI: 13.4 to 20.8) of teenagers with MS, followed by the ATP-III criterion with 4.3% (95%CI: 2.3 to 6.3); the other criteria identified a lower frequency. The best concordance was found between the AHA and ATP-III criteria (k = 0.905); the WHO and IDF criteria had a coefficient of 0.628. The five criteria coincided in classifying six adolescents (1.5%) as MS. CONCLUSIONS.: The AHA and ATP-III criteria modified by Cook had almost perfect concordance, which was also found for both sexes. The ATP-III, Ferranti, IDF, AHA and WHO criteria agree in less than 2% when identifying MS in the same group of adolescents.
