title: [Epidemiological study on metabolic syndrome in Chengdu adult in 2007].
abstract: OBJECTIVE
  To investigate the prevalence of metabolic syndrome (MS) and associated factors in the adults in Chengdu.
  
  
  METHODS
  A cross-sectional survey was undertaken in 2242 residents over 20 years of age. The cluster sampling method was employed to recruit participants from Yulin and Longquan communities in Chengdu. The metabolic syndrome was defined by IDF 2005.
  
  
  RESULTS
  The prevalence of MS was 17.2%, with 15.0% and 18.6% for male and female, respectively. The age-adjusted rate of MS was 13.47%, with 17.71% and 11.09% for male and female, respectively. The difference in prevalence of MS between male and female was significant. The prevalence of central obesity, hypertension, hyperglycemia, high triglycerides, low HDL-C were 31.6%, 32.0%, 16.5%, 30.4%, and 31.2% respectively, which became 26.3%, 26.0%, 12.9%, 26.9%, and 30.5% respectively after age-adjustment. Gender differences appeared in all of the components of MS except for low HDL-C (P < 0.05). The multivariable stepwise analysis extracted age, history of hypertension, blood pressure, waist circumference, fasting glycaemia level and triglyceride as major risk factors for MS and blood HDL-C level as a protective factor of MS.
  
  
  CONCLUSIONS
  The prevalence of MS is considerably high in Chengdu. It will continue to rise thanks to the social economic development and population ageing. There is an urgent need to take actions to reduce the burden of MS.
