title: The relationship between periodontitis and metabolic syndrome among a Korean nationally representative sample of adults.
abstract: OBJECTIVE
  The aim of this study was to examine whether metabolic syndrome (MS) is associated with periodontitis in a representative sample of Korean adults, who were involved in the Fourth Korea National Health and Nutrition Examination Survey (KNHANES).
  
  
  METHODS
  A total of 7178 subjects over the age of 19 years who participated in KNHANES were examined. MS was defined as the definition proposed by the National Cholesterol Education Program Adult Treatment Panel III and the abdominal obesity cut-off line based on Korean Society for the Study of Obesity. The periodontal status was assessed by the Community Periodontal Index. Multivariate logistic regression analysis was carried out adjusting for the sociodemographics, oral health behaviours and status, and health behaviour. All analyses considered a complex sampling design, and multivariate analysis was also performed in the subgroups (age, gender, current smoking status).
  
  
  RESULTS
  Multivariate logistic regression analysis revealed significant associations between MS and periodontitis. After adjusting for all covariates, the adjusted odds ratio (OR) of periodontitis (community periodontal index ≥ 3) was 1.55 (1.32-1.83) for MS. In subgroup analysis, periodontitis is associated with MS in subjects over age 40 and the adjusted ORs were higher in females and in the smoker group than in males and in non-smokers.
  
  
  CONCLUSIONS
  MS is associated with periodontitis.
