Abstract

Background Inflammatory bowel disease (IBD) is a complex and chronic condition of the gastrointestinal tract. Diet is a significant factor influencing the onset and course of IBD. The Diet Quality Index (DQI) is an essential tool for evaluating dietary patterns against international standards. The objective of this study was to investigate the relationship between DQI with inflammatory indices and body mass index (BMI). Materials and methods This cross-sectional study was conducted on 152 adult patients with IBD. Demographic, anthropometric indicators (height, weight, BMI) and nutritional status (with food frequency questionnaire (FFQ)) were measured. Inflammatory indices (CRP, ESR, calprotectin, and ferritin) were determined. DQI was calculated from the results obtained from the diet. Results 152 patients with a mean age of 42.6 ± 13.16 years, a BMI of 25.44 ± 4.9 kg/m2, and a DQI of 63.49 ± 7.74 participated in the study. IBD in most patients (77%) was ulcerative colitis. The results indicated no significant difference in the serum levels of inflammatory indices and BMI when comparing patients across different tertiles of the DQI (P > 0.05). There was no significant relationship between DQI tertiles and the serum level of Inflammatory indices and BMI in the crude model (P > 0.05). In the adjusted model, there was a significant positive relationship between the second tertiles of DQI and ESR (P = 0.03) and in other indices, no significant relationship was observed (P > 0.05). Conclusion This study did not find a significant relationship between DQI and inflammatory indices or BMI in IBD patients. © The Author(s) 2025.
