Association Serum Lipid Levels with Periodontal Disease in Korean Adults Over the Age of 50: The Korea National Health and Nutrition Examination Survey, 2016-2018

in adults over the age of 50 is rapidly increasing, the association between serum lipid levels and periodontal disease in Korean adults over the age of 50 still remains to investigate. Thus, the aim was to deter-mine the effect of serum lipid levels on periodontal disease in older adults over the age of 50 using data from the seventh Korea National Health and Nutrition Examination Survey. METHODS: The study used the data of 809 adults aged ≥50 years targeted in the 7th Korea National Health and Nutrition Examination Survey, 2016-2018. Levels of total cholesterol, triglyceride, high density- lipoprotein (HDL-cholesterol), and low density-lipopro-tein (LDL-cholesterol) and periodontal conditions were measured. Complex-sample chi square test and linear regression were used to analyze the relationship serum lipid levels with periodontal disease. RESULTS: The results of chi square tests showed that the prevalence of periodontal disease among the elderly ≥50 years were statistically significant differences according to gender, age, education level, marital status, and smoking status. After adjusting for all con-founding factors, HDL-cholesterol alleviated periodontal disease, while LDL-cholesterol exacerbates periodontal disease. However, total cholesterol and triglycerides were not connected with periodontal disease. CONCLUSIONS: Therefore, controlling HDL and LDL cholesterol levels through physical exercise could be a preventative measure for periodontal disease.
