title: Prevalence of metabolic syndrome and its relationship with physical activity in suburban Beijing, China.
abstract: BACKGROUND
  The present study aimed to estimate the up-to-date prevalence of metabolic syndrome and its relationship with physical activity among suburban adults in Beijing, China.
  
  
  METHODS
  A cross-sectional survey in a representative sample of 19,003 suburban adults aged 18-76 years was carried out in 2007-2008. Data was collected via questionnaires and blood pressure, anthropometric, and laboratory measurements.
  
  
  RESULTS
  Of the residents aged 18-76 years in suburban Beijing, 25.9% (27.3% in men and 25.1% in women), 21.3% (19.4% in men and 22.9% in women), and 25.3% (24.2% in men and 26.1% in women) had 1 component, 2 components, and 3 or more components of metabolic syndrome, respectively. The age-standardized prevalence of metabolic syndrome and its components, including abdominal obesity, elevated triglycerides, reduced high-density lipoprotein cholesterol, elevated blood pressure, and elevated fasting plasma glucose, decreased across categories with increasing physical activity. After adjusting for age, sex, education level, smoking, and alcohol consumption, residents were more likely to have metabolic syndrome across categories with decreasing physical activity; a similar relationship also applied to components of metabolic syndrome.
  
  
  CONCLUSIONS
  A high prevalence of metabolic syndrome and its components is commonly present in suburban Beijing. Increasing physical activity can reduce the relative risk of metabolic syndrome and it components.
