Analysis of the related factors of periodontitis in Ningbo petrochemical company staff / 中国基层医药

ABSTRACT

Objective To find out the prevalence of periodontitis in a petrochemical industry community in Ningbo ; to identify the possible factors of the prevalence; to evaluate the impact of the polluted environment on the oral health of the employees;and to provide information to the enterprises in oral diseases prevention.Methods 2 108 peoples who received regular physical examination in a petrochemical industry community in Ningbo was included.To each subject,a periodontal examination according to the principles and fundamental methods which were used in the third national oral health epidemical survey was carried out,the fast blood was phlebotomized,total cholesterol(TC),triglyceride (TG),uric acid,blood glucose and other serum indexes levels were recorded.These subjects were stratified into two age groups.Data was analyzed with x2 test and multiple regression.Results In the group of 2 108 selected subjects,the periodontitis rate was 52.3 ％ [95 ％ CI(52.3 ± 2.1) ％].In the multivariable logistic regression model,the old-age groap age(OR =4.783,P =0.000),blood pressure (OR =1.526,P =0.001) and blood glucose (OR =1.560,P =0.045) were the risk factors of periodontitis,while the environmental factor(OR =0.661) was excluded.In the young and middle-age group,blood pressure (OR =2.184,P =0.000),blood glucose (OR =2.314,P =0.001),TC(OR =1.356,P =0.003),and alcohol (OR =1.382,P =0.02) were the risk factors of periodontitis.Conclusion The levels of blood glucose,TC,blood pressure and alcohol should be considered in periodontitis prevention and the sulfureted hydrogen-based environment factor had no adverse impact on periodontitis.
