Determinants of metabolic syndrome in middle-aged Chinese men
Document Actions
Opting for one versus another concurrent definition of the metabolic syndrome can markedly impact its epidemiological prevalence. This study aimed to estimate the prevalence and lifestyle risk factors of metabolic syndrome in urban Chinese men participating in the Shanghai Men’s Health Study according to three metabolic syndrome definitions: International Diabetes Federation (IDF), ATP III, and a modified version of the ATP III criteria for Asian populations (ATP III-modified criteria). The prevalence of metabolic syndrome was estimated at 18.6% by IDF criteria, 18.4% by ATP III criteria, and 29.3% by ATP III-modified criteria. Whereas agreement between IDF and ATP III criteria was moderate, agreement between ATP III-modified and the two other criteria was good. Regardless of the criteria used, physical activity was associated with a lower prevalence, while drinking more than three alcoholic beverages per day was associated with a higher risk of metabolic syndrome. However, the association between smoking and metabolic syndrome risk failed to reach statistical significance. In conclusion, physical activity is associated with decreased and high alcohol consumption with increased risk of having a metabolic syndrome phenotype.
