Association between oral health behavior and chronic diseases among middle-aged and older adults in Beijing, China

OBJECTIVES: To evaluate the association between oral health behavior and multiple chronic diseases among middle-aged and older adults. METHODS: We obtained data of the Beijing Health Service Survey and used multivariate logistic models to estimate the association between oral hygiene behavior and the risk of chronic diseases. RESULTS: The risk of any chronic diseases (OR = 1.27, 95% CI: 1.18–1.37), cardiovascular diseases (CVD, OR = 1.30, 95% CI: 1.21–1.39), and endocrine or nutritional metabolic disorders (OR = 1.11, 95% CI: 1.01–1.22) was higher in those who with poor oral health behavior. There was no significant correlation between oral health behavior and the risk of diseases of the musculoskeletal, respiratory, digestive, and genitourinary systems. CONCLUSIONS: Poor oral hygiene practices were associated with higher risk of chronic diseases, CVD and diabetes mellitus (DM) among middle-aged and older adults. These findings motivate further studies to evaluate whether improved oral health behavior may prevent the incidence of chronic diseases.
