[Correlation between periodontitis and metabolic syndrome of the middle-aged and aged population in Shijingshan community of Beijing].
OBJECTIVE
To survey the metabolic status of the middle-aged and aged population with periodontitis in Shijingshan community of Beijing, and  investigate the relationship between periodontitis and metabolic syndrome (MS).


METHODS
The middle-aged and aged population in the community  were investigated by questionnaires, periodontal clinical examinations and blood biochemical tests in 2005. A total of 903 subjects were enrolled, who  were divided into two groups by severity of periodontitis. Their waist circumferences, values of high-density lipoprotein cholesterol (HDL-C), systolic  blood pressure, fasting glucose, MS and its individual components (central obesity, insulin resistance, hypertriglyceridemia, low HDL-C and  hypertension) were compared between the two groups. The Logistic regression model was set to analyze the relationship between periodontitis and MS.


RESULTS
There was a significantly higher mean of systolic blood pressure, fasting glucose in the subjects with moderate-severe periodontitis than that  with no-mild periodontitis. With severity of periodontitis increasing, the prevalence of MS, high blood glucose and low HDL-C increased significantly.  After adjustment for gender, age, and smoking, the subjects with moderate-severe periodontitis were 1.524, 1.527 and 2.349 times more likely to suffer  from MS, high blood glucose and low HDL-C than those with no-mild periodontitis, respectively.


CONCLUSIONS
With severity of periodontitis increasing,  the prevalence of MS, high blood glucose and low HDL-C increased significantly in the middle-aged and aged population of the community in Beijing.  Severity of periodontitis is associated with MS, high blood glucose and low HDL-C.
