Abstract
OBJECTIVES: An association between metabolic syndrome (MetS) and periodontal status has recently been focused on. However, no study has investigated the relationship between the prevalence of MetS and the decline of masticatory performance. We aimed to clarify the relationship between MetS and objective masticatory performance using the standardized test food in a general urban Japanese population. METHODS: We studied 1780 Japanese men and women (mean age, 66.5 years) using the Suita study. MetS was defined using the uniform definition proposed in the 2009 Joint Interim Statement. Masticatory performance was evaluated by a chewing test using gummy jelly. Prevalence of MetS among quartiles of masticatory performance was compared using multiple logistic regression analysis adjusting for sex, age, drinking and smoking status, and periodontal status evaluated by the Community Periodontal Index. RESULTS: Compared to the highest quartile of masticatory performance, the 2nd quartile showed a 1.46-fold increase in the prevalence of MetS (trend P=0.159). In addition, Analysis by age showed 1.67-, 1.90- and 1.74-fold increases in the prevalence of MetS in the 3rd, 2nd and 1st quartiles among individuals in their 70s, respectively (trend P=0.094). However, individuals in their 50s and 60s showed no significant relationship between masticatory performance and MetS. CONCLUSIONS: These findings suggested that masticatory performance are inversely associated with the prevalence of MetS independent of periodontal disease, especially in the elderly. CLINICAL SIGNIFICANCE: Declines in objective masticatory performance might be associated with the prevalence of MetS, independent of periodontitis. Given our results, treatments aimed at maintaining and recovering masticatory performance may represent important dental care to mitigate the risk of MetS.
