Waistline to gumline: body mass index in treated periodontitis patients
Objectives: Periodontal disease affects 42% of adults in the US. It has been suggested that both the periodontal oral microbiome and host immuno-inflammatory response may be associated with overweight/obesity. This retrospective analysis sought to determine the association of periodontal disease parameters with body mass index (BMI) and obesity status in patients who had received prior treatment for periodontitis.
Methods: 608 patients undergoing maintenance therapy who had been previously treated for periodontitis at the University of Alabama School of Dentistry (UAB) were assessed with regard to periodontal disease condition, self-reported body mass index, sites with probing depth (PD) > 3, missing teeth, gender, age, race/ethnicity, and bleeding on probing (BOP). Patients were determined to have moderate to severe periodontitis if they presented with >/=2 sites in 2 different quadrants with CAL >/= 5mm and PD >/= 5mm. Individuals were also categorized as being under/normal weight, overweight, and obese if they had BMI values of < 25 kg/m2, 25-<30 kg/m2, and >/=30 kg/m2. In this population BMI ranged from 16.827-51.389 kg/m2, respectively.
Results: Chi-squared test was used to evaluate odds ratios for periodontitis status by obesity status. Periodontitis status was not statistically significantly associated with overweight and obese status (OR) of 1.388 [0.961-2.006] and 1.168 [CI 0.77-1.757], respectively. Female gender and age were negatively associated with periodontitis status (OR 0.561 [CI 0.343-0.918] and 0.983 [CI 0.967-0.999], respectively. Obese patients did demonstrate significantly more sites with BOP than either normal/underweight or overweight patients and Spearman Correlation Coefficients demonstrated that obesity status was associated with age and missing teeth (p<0.001 and p=0.0064, respectively).
Conclusions: In patients receiving periodontal maintenance who had received previous periodontal therapy, BMI was associated with age and missing teeth and obese status was associated with a significant increase in sites with BOP.
