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.
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.
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.
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.
