| Outline of Final Research Achievements |
Although many previous studies have reported that there is a significant relationship between obesity and periodontal disease, it is unclear whether or not physical activity in daily life that is intimately related to obesity has some beneficial effect on periodontal health status. We conducted a large-scale athletic epidemiological study to evaluate physical activities using an accelerometer, and examined epidemiological relationship between obesity, physical activity, and periodontal disease. As a result of a multivariate logistic regression analysis using periodontal disease as a dependent variable and physical activity, body-mass index, and other confounding variables as independent variables, subjects with high physical activity level had significantly lower odds ratio for periodontal disease than the subjects with low that level. The result of this study suggests that physical activity in daily life may have a beneficial effect on maintaining healthy periodontal status.
