Study on clustered components of metabolic syndrome in residents of Jiangsu province

Objective To analyse whether the components of the metabolic syndrome(MS)tend to cluster rather than occur by coincidence and to describe the distribution of MS components in residents of Jiangsu province.Methods 6 571 adults were recruited fr om the population of prevention progr am of multiple metabolic disorders and MS in Jiangsu province.The National Cholesterol Education Program Adult Treatment Panel Ⅲ Asian criteria was used to define MS.The Bayliss theorem was used to determine whether the components of MS have a char acter of clustering or not.Results The prevalence of some(ten out of sixteen)combinations of components were much higher than expected(P<0.01),meanwhile,the prevalence of a combination of three or more components of MS was higher than the predicted one as the growing number of the components.The prevalence of obesity(76.73%/14.94%)and elevated fasting plasma glucose(34.02%/6.73%)were much higher in MS when compared with the prevalence of individuals without MS.Conclusion The components of MS are really clustered r ather than occured by coincidence,and the obesity and elevated fasting plasma glucose are clustered more often than other components of MS.
