A Study on the Relationship between Oral Disease and Systemic Diseases Using Original Data of National Health and Nutrition Survey

Objective: This study aimed to investigate the associations between periodontal disease and systemic conditions-specifically diabetes mellitus, dyslipidemia, asthma, and allergic rhinitis-using data from the 8th Korea National Health and Nutrition Examination Survey (KNHANES).Methods: A total of 6,728 individuals from the 2021 KNHANES dataset were included.Variables related to periodontal health (gum treatment history, chewing discomfort, occlusal discomfort) and systemic disease diagnoses were analyzed.Statistical methods included descriptive statistics, correlation analysis, one-way ANOVA, and multiple regression analysis to determine significant associations between gum disease and systemic conditions.Results: Significant associations were found between periodontal treatment and systemic disease diagnoses: dyslipidemia (t = -4.896,p < .001),diabetes (t = .336,p < .001),and allergic rhinitis (t = 6.108, p < .001).Additionally, asthma treatment was significantly associated with gum treatment history (F = 13.915,p < .001).However, no significant association was found between alcohol consultation and periodontal disease.Conclusion: The findings suggest that periodontal disease is significantly associated with several systemic conditions, including diabetes, dyslipidemia, asthma, and allergic rhinitis.These results underscore the importance of interdisciplinary healthcare approaches that integrate oral health into chronic disease management strategies.
