[Prevalence and epidemic characteristics of metabolic syndrome among adult residents in Nanjing City in 2010-2013].

OBJECTIVE

To understand the prevalence and epidemic characteristics of metabolic syndrome(MS) among adult residents in Nanjing City.

METHODS

In 2010-2013, a total of 4918 adult residents in Nanjing City were surveyed using a multi-stage stratification and population proportional clustering random sampling method. Questionnaires, physical examinations and laboratory examinations were conducted to collect the basic conditions, health history of the subjects and related indicators including height, weight, waist circumference, blood pressure, fasting blood glucose, total cholesterol, triglycerides, high-density lipoprotein cholesterol, etc. The 2009 International Joint Interim Statement(JIS) was used to filter patients with metabolic syndrome.

RESULTS

Among the 4918 surveyed subjects, 1627 were MS, with a crude prevalence rate of 33. 1% and an age-standardized prevalence rate of 26. 3%, the standardized prevalence rate of MS was 29. 0% in males and 24. 8% in females. Age-standardized prevalence rates between different genders had no significant statistical difference(χ2=1. 352, P=0. 245). There were significant statistical differences between the crude prevalence rate of MS among subjects of different ages(χ2=132. 557, P<0. 001), occupations(χ2=87. 572, P<0. 001)and educational level(χ2=26. 077, P<0. 001). Patients with a family history of hypertension(χ2=26. 582, P<0. 001) and a family history of diabetes(χ2=16. 013, P<0. 001)had a higher prevalence of MS.

CONCLUSION

The prevalence of metabolic syndrome in adult residents in Nanjing City in 2010-2013 was relatively high.
