  • Background: Obesity and periodontitis are associated with an inflammatory background. Inflammatory mediators involved may have reciprocal effects on one another. In this study, the levels of inflammatory mediators implicated in overweight or obese status and periodontitis are simultaneously evaluated.

    Methods: Body mass index (BMI) and waist circumference, periodontal disease status, and plasma levels of adiponectin, leptin, intercellular adhesion molecule (ICAM)-1, vascular cell adhesion molecule 1, C-reactive protein (CRP), immunoglobulin (Ig)G antibody against Porphyromonas gingivalis, and IgG against Aggregatibacter actinomycetemcomitans in 109 periodontitis participants with various BMIs were measured. BMI ≥23.0 kg/m2 was considered overweight or obese.

    Results: Plasma adiponectin was decreased (P = 0.04), whereas CRP and IgG against P. gingivalis were increased (P = 0.04 and P = 0.001, respectively) in patients with severe periodontitis compared with patients with mild or moderate periodontitis, independent of overweight or obese status. Plasma CRP, ICAM-1, and leptin were increased (P <0.001, P = 0.007, and P <0.001, respectively) and adiponectin was decreased (P = 0.04) in overweight or obese participants compared with normal weight participants, without influence of periodontitis severity. No interaction effect between periodontitis and overweight or obese status existed for these protein levels after the data were adjusted for age, sex, plasma levels of triglycerides, high-density lipoprotein cholesterol, fasting plasma glucose, and blood pressure (P = 0.48).

    Conclusions: Periodontitis and overweight or obese BMI change plasma levels of the inflammatory mediators adiponectin and CRP, independently. This study suggests a role of periodontitis in systemic inflammatory response in Thai people who are overweight or obese.
