Purpose: To expand upon the current evidence that there is an association between BMI and periodontal disease using a retrospective study design with a larger sample size, and thereby a greater statistical power than previously performed studies. We hypothesize that BMI is positively correlated with prevalence of periodontal disease.
Materials and Methods: Data from the electronic health records maintained by the University of Pittsburgh School of Dental Medicine from August 2008 to February 2014 was extracted for variables including age, gender, ethnicity, smoking history, diabetes, probing depths, height, and weight. Multivariate logistic regression was performed to determine the odds ratio for the association between periodontal disease status and all the other variables (BMI, age, ethnicity, gender, smoking status, and diabetes).
Results: A total of 27,052 subjects were included in the data set. Multivariate analysis of the data showed that the odds ratio of having periodontal disease with a BMI greater than or equal to 30 versus less than 30 was 1.22 when accounting for all the other confounding variables (p=0.013). Furthermore, sex, age, ethnicity, and smoking were all associated with statistically significant odds ratio for development of periodontal disease when analyzed accounting for the other confounding variables (p<0.001). Only diabetes did not show a statistically significant correlation with periodontal disease (p=0.394).
Conclusion: Our results reaffirm that increased BMI is positively correlated with periodontal disease prevalence.
