Aim:
To evaluate the dietary profile and concentrations of soluble receptors for advanced glycation end products (sRAGE) and interleukin-6 (IL-6) in overweight or obese individuals with periodontitis.
Methods:
Ninety-eight adults aged 18-59 years were classified into four groups: Normal weight no periodontitis (n = 27), normal weight with periodontitis (n = 21), overweight/obesity no periodontitis (n = 26) and overweight/obesity with periodontitis (n = 24). Dietary, clinical, anthropometric, and biochemical data were collected. sRAGE and IL-6 concentrations were measured in serum and gingival crevicular fluid (GCF) using ELISA.
Results:
Overweight/obesity and periodontitis group showed reduced serum sRAGE concentrations 979 [770-1193] pg/mL and elevated GCF IL-6 levels 11.4 [10.0-13.3] pg/mL (p < 0.05). Serum sRAGE and GCF IL-6 showed significant correlations with periodontal parameters, including probing pocket depth, clinical attachment loss, and number of diseased teeth (r = 0.40; p < 0.001). Despite higher total nutrient intake, overweight/obesity with periodontitis group had the highest energy intake and the highest prevalence of inadequate intake for protein (79%), calcium (92%), vitamin B5 (83%), and cholesterol (83%).
Conclusions:
Obesity and periodontitis were associated with lower serum sRAGE, higher GCF IL-6, and more frequent dietary inadequacies, suggesting a potential link between nutritional status, inflammatory biomarkers, and periodontal health.
