Association between periodontitis and dyslipidemia based on the fourth Korea National Health and Nutrition Examination Survey

Abstract

Aims: The aim of this study was to examine whether dyslipidemia 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).

Materials and methods: A total of 18,210 subjects over 19 years of age who participated in KNHANES were examined. Dyslipidemia is defined according to the definition proposed by the Korean Society of Lipidology and Atherosclerosis. The periodontal status of the patients was assessed by the Community Periodontal Index (CPI). Multivariate logistic regression analysis was carried out and adjusted for sociodemographics, oral health behaviors and status, and general health behavior. All analyses considered a complex sampling design, and multivariate analysis was also performed in the subgroups (age, gender, and current smoking status).

Results: Multivariate logistic regression analysis revealed significant associations between dyslipidemia except pre-hypercholesterolemia and periodontitis. In the subgroup analysis, periodontitis was significantly associated with hypo-HDL-cholesterolemia and had a potential association with hyper-TG in subjects younger than 40 years. The adjusted ORs were greater in the present smoker group than the non-smoker group.

Conclusions: Dyslipidemia except pre-hypercholesterolemia is associated with periodontitis.
