Objective To evaluate the correlation between periodontitis and life style. Methods By using randomized cluster sampling method,2990 health check-up receivers were enrolled in this cross sectional survey from September 2007 to September 2008. The participants were requested to fill in a questionnaire to assess community periodontal index and synthesis grades. Multiple linear regression was used for data analysis. Results Gender (P = 0. 000) , age (P = 0. 000 ) , educational level ( P = 0. 001) , smoking (P = 0.011 ) and duration of teeth brush ( P = 0.026 ) were positively correlated with periodontitis. However, periodontitis showed no relationship with alcohol consumption, food intake, daily activity,frequency of teeth brush, periodontal bleeding. Conclusion Periodontitis is a condition with multiple risk factors. Improving life style may help to prevent general population from periodontitis.
