A factor of periodontal disease and dietary patterns in Korean adults using data from Korea National Health and Nutrition Examination Survey V / 대한구강보건학회지

ABSTRACT

OBJECTIVES: This study was aimed to identify the socioeconomic factors, health behavior factors and dietary patterns that have an influence on the periodontal disease in adults. METHODS: This study used data collected from the fifth Korea National Health and Nutrition Examination Survey (NHANES V-1). The final sample included 2,386 subjects who were 30-59 years old and who had completed the necessary health examinations, the health behaviors survey and nutrition survey. RESULTS: Eleven dietary patterns emerged from the factor analysis with different factor loading. After controlling for potential confounders, multiple logistic regression analysis of the dietary patterns showed that 'legumes/mixed grains' and 'instant foods' affected the periodontal disease. Lower consumption of 'legumes/mixed grains' and higher consumption of 'instant foods' were significantly associated only with an increased risk of periodontal disease. CONCLUSIONS: In the light of the results of this study, it appears pretty likely that the risk of developing periodontal disease can be reduced by changing a person's dietary patterns.
