Background: Individuals with inflammatory bowel disease (IBD) require medical nutrition therapy (MNT) to manage gastrointestinal symptoms and mitigate inflammation to reduce risk of malnutrition associated with inadequate nutrient intake. Revealing current dietary patterns is essential to identify behavior modifications needed to improve MNT and promote nutritional adequacy. Objective: To expand the understanding of dietary patterns, diet quality and nutrient intake of a sample of individuals with IBD to identify behavior modifications needed to improve adherence to MNT delivered by a Registered Dietitian Nutritionist (RDN). Methods: A cross-sectional study was conducted in patients with IBD (N=47). Ulcerative colitis (UC) and Crohn’s disease (CD) diagnoses were confirmed in the electronic medical record. A validated web-based, graphical food frequency questionnaire (FFQ) was used to assess nutrient intakes. The Healthy Eating Index (HEI-2015) and alternate Mediterranean diet score (aMED) were compared between diagnoses using a Mann Whitney U test using median values. Average intakes of specific nutrients were compared to dietary reference standards. Results: Comparing UC and CD, there were no significant differences in HEI-2015 scores (62.9 vs 54.9, respectively; p=0.473) or aMED scores, however a trend was observed for greater adherence to the Mediterranean diet (MD) in the UC group (5 vs 3, respectively; p=0.164). UC and CD failed to meet recommended fiber intake (16.2 g vs 16.1 g, respectively). Dietary patterns in UC and CD reflected an imbalance in dietary fat intake with less than 35% of patients meeting recommendations for saturated fat (35% vs 20%, respectively). Majority of UC and CD participants met recommendations for added sugar intake (37 g vs 43.1g, respectively). Conclusions: Similar dietary patterns are observed between diagnoses indicating poor adherence to the Dietary Guidelines for Americans and the Mediterranean Diet. Poor diet quality may be associated with low fiber and high saturated fat consumption, indicating areas for behavior modifications. Shared gaps in adherence exist, necessitating MNT to improve diet quality and reduce malnutrition risk. Acknowledgments: Funding supported by CTSA, grant number UL1TR002733
