Prevalence of metabolic syndrome in Chinese adolescents under five diagnostic criteria
Objective Five different diagnostic criteria for metabolic syndrome(MetS)were used to describe the differences in the detection rates of MetS among Chinese adolescents so as to provide references for MetS prevention and control in the adolescents.Methods Based on the China Health and Nutrition Survey,the detection rates of MetS among Chinese adolescents aged 12-17 years were calculated separately using the Chinese definition(abbreviated as the CHN2012 definition)recommended by the Pediatric Academy of Chinese Medical Association,the International Diabetes Federation criterion(abbreviated as the IDF criterion),the Cook criterion,the Noubiap criterion and the modified definition of MetS based on IDF criteria(the MetS-IDFm criterion).Kappa test was used to evaluate the consistency.Results The overall detection rate of MetS under the Noubiap criterion was found to be the highest(5.61%),followed by the Cook criterion(4.76%),the MetS-IDFm criterion(3.27%),the CHN2012 definition(2.56%)and the IDF criterion(1.35%).Under the five diagnostic criteria,the detection rates of MetS were all higher in males than in females,and the detection rates of hypertension and high triglyceride were the highest among all components.Among the total population and males,the consistency was found to be the strongest between the Cook and Noubiap criteria,with the Kappa values being 0.913 and 0.923 respectively.Among females,the consistency was found to be the strongest between the CHN2012 definition and the MetS-IDFm criterion,with the Kappa value being 0.956.Conclusion Overall,the detection rate of MetS under the Noubiap criterion is found to be the highest in the adolescents,and it is in good agreement with that under the Cook criterion.The detection rate of MetS under the IDF criterion is found to be the lowest in the adolescents,and it is in poor agreement with those under the other criteria.
