Abstract: Objective: To explore the influencing factors of dietary types and dietary patterns on the outcome of chronic periodontitis (CP). Methods: The dietary data were collected from the project "China Northwest Cohort, CNC" database, and A total of 1000 CP people were selected. According to the American CDC's diagnostic criteria for chronic periodontitis, the study population was divided into four groups: healthy, mild, moderate, and severe CP groups. The lasso regression was used to screen 47 dietary variables. Only those variables demonstrating significance both in univariate regression and lasso regression were included in the multivariate regression model. Results: It was concluded that the risk of CP by consuming 40-75g of animal viscera per day was 1.70 times higher than that of intake less than 40 g (95%CI: 1.16-2.48, P<0.05). Compared with not eating sunflower oil, the OR of eating sunflower oil was 1.58 (95%CI: 1.12-2.22, P<0.05). Besides, compared with not eating fried food, the OR value of eating 1-3 times per month was 0.66 (95%CI: 0.43-1.01, P>0.05). Conclusion: The selection of animal viscera as the only meat food, excessive intake of sunflower oil, and fried foods with a frequency of more than once a week may associate with the progress of CP.
