Abstract Background: Metabolic syndrome (MetS) is characterized by a cluster of signs of metabolic disturbance and has caused a huge burden on the health system. The study aims to explore the prevalence and characteristics of MetS defined by different criteria in the Chinese population.Methods: Using the data of the China Hypertension Survey (CHS), a nationally representative cross-sectional study from October 2012 to December 2015, a total of 28717 participants aged 35 years and above were included in the analysis. The MetS definitions of the International Diabetes Federation (IDF), the updated US National Cholesterol Education Program Adult Treatment Panel III (the revised ATP III), and the Joint Committee for Developing Chinese Guidelines (JCDCG) on Prevention and Treatment of Dyslipidemia in Adults were used. Multivariable logistic regression was used to identify factors associated with MetS.Results: The prevalence of MetS diagnosed according to the definitions of IDF, the revised ATP III, and JCCDS was 26.4%, 32.3%, and 21.5%, respectively. The MetS prevalence in men was lower than in women by IDF definition (22.2% vs. 30.3%) and by the revised ATP III definition (29.2% vs. 35.4%), but the opposite was true by JCDCG (24.4%vs 18.5%) definition. The consistency between the three definitions for men and the revised ATP III definition and IDF definition for women was relatively good, with kappa values ranging from 0.77 to 0.89, but the consistency between the JCDF definition and IDF definition (kappa = 0.58) and revised ATP III definition (kappa = 0.58) was poor. Multivariable logistic regression showed that area, age, education, smoking, alcohol use, and family history of cardiovascular disease were factors related to MetS, but the effects and correlation intensity of these factors varied with gender and definition.Conclusions: The prevalence and characteristics of the MetS vary according to the definition used in the Chinese population. The three MetS definitions are more consistent in men but relatively poor in women. On the other hand, regardless of the definition used, metabolic syndrome is common in China, so it is necessary to take targeted measures to reduce its harm.

Huang et al. (2022) conducted a cross-sectional in Metabolic syndrome (n=28,717). Diagnostic definitions of metabolic syndrome (IDF, revised ATP III, JCDCG) vs. Comparison across IDF, revised ATP III, and JCDCG diagnostic definitions was evaluated on Prevalence of metabolic syndrome. Different diagnostic criteria yielded metabolic syndrome prevalence of 26.4% (IDF), 32.3% (revised ATP III), and 21.5% (JCDCG) in Chinese adults aged ≥35 years.
