Résumé
BACKGROUND: The development of sarcopenia and periodontitis is multifactorial, and several factors that play a role in periodontitis are thought to contribute to sarcopenia. This study evaluated the association between periodontitis and sarcopenia using data from the 2008–2009 Korea National Examination Survey.METHODS: We used the data of 2,340 Korean adults aged more than 65 years from the 2008–2009 Korean National Health and Nutrition Examination Survey. Sarcopenia was defined as the appendicular skeletal muscle mass divided by weight (kg/kg) <2 deviations less than the sex-specific mean for young adults. Periodontal health .was measured using the Community Periodontal Index (CPI), and periodontitis was defined as a CPI score of 3 or 4.RESULTS: Analysis using the chi-square test and linear logistic regression showed that the prevalence of periodontitis increased significantly. The odds ratio (OR) (95% confidence interval [CI]) for sarcopenia was 2.498 (1.366–4.569). After adjusting for age and sex, the OR (95% CI) was 2.430 (1.323–4.465). The OR (95% CI) after adjusting for age, sex, diabetes mellitus, osteoarthritis, osteoporosis, and cancer was 2.168 (1.160–4.051).CONCLUSION: Sarcopenia is a representative lifestyle disease associated with periodontitis. In addition, sarcopenia is related to poor quality of life, especially mobility and usual activity. Therefore, greater attention must be paid to patients with periodontitis and they must be evaluated for sarcopenia to prevent and improve poor quality of life.
