title: [Correlation between hyperglycemia levels and periodontitis in 545 officeholders in Nantong city].
abstract: OBJECTIVE
  To identify the relationship between hyperglycemia levels and periodontitis by investigating the levels of hyperglycemia and periodontal conditions of officeholders in Nantong city.
  
  
  METHODS
  From January 2013 to January 2014, 545 officeholders were randomly selected in Nantong City who underwent physical examination and divided into 2 groups: young of middle-aged adults(≤60 years) and old adults (>60 years). The data was analyzed with Chi-square test and multi-factors logistic regression by using SPSS 16.0 software package.
  
  
  RESULTS
  There was a significant correlation between blood glucose levels and periodontitis. Multi-factor Logistic regression analysis showed that in the whole population, smoking, age, blood glucose levels were significantly correlated with the degree of periodontitis (P<0.05). Smoking and low level of education were associated with periodontitis in young and middle-aged adults. In old people, blood glucose level more than 7.0 mmol/L and smoking were the risk factors for periodontitis.
  
  
  CONCLUSIONS
  Hyperglycemia level is risk factor for periodontitis, which has an effect mainly on old adults.
