Background

Many patients with IBD believe diet affects the course of disease and is at least as important as medication in their IBD treatment. However, easy assessment of patients’ food intake and structured support of a healthy diet are lacking. The Eetscore is an online tool which assesses diet quality and subsequently gives personal dietary advice. We used the Eetscore to assess diet quality of IBD patients, evaluated if diet quality improved over time and studied correlations with quality of life (QoL) and clinical disease activity.

Methods

A prospective cohort study with adult IBD patients was performed. Participants completed the Eetscore, the short IBDQ and a clinical disease activity questionnaire (P-HBI or P-SCCAI) at baseline and after 1 month. The Eetscore is a validated web-based screening tool to assess diet quality based on 16 food components (e.g. meat, vegetables, fruit and fish). It consists of a short Food Frequency Questionnaire and is scored with the Dutch Healthy Diet 2015-index based on the Dutch dietary guidelines. The score of each component ranges from 0 to 10, resulting in a total score between 0 and 160. Higher scores indicate better adherence to Dutch dietary guidelines. The Eetscore subsequently provides personalised dietary advice based on the assessment. We assessed changes over time using paired samples t-tests or McNemar’s test and correlations using Pearson’s or Spearman’s correlation.

Results

We included 212 participants. At time of this preliminary analysis, 175 participants (60% female, 49% Crohn’s disease) completed baseline and 1-month assessments. Their median age was 49 years [IQR 32-58], BMI 25 kg/m2 [IQR 22-28] and disease duration 10 years [IQR 4-18]. At baseline, mean Eetscore was 98 ± 19, with highest median scores (≥8.5) on red meat, fat and oils, sweetened beverages, alcohol and salt intake, and lowest median scores (≤5) on nuts, legumes, processed meat and unhealthy choices (Figure 1). Diet quality increased with 5.6 points (95%CI 3.7-7.5) to a mean Eetscore of 103 ± 21 (p<0.001) after 1 month. QoL improved from 53 ± 10 to 55 ± 9 (∆2.0 (95%CI 1.2-2.8); p<0.001). The proportion of participants with clinically quiescent disease was comparable at both time points (71% vs 74%, p=0.29). Diet quality was not correlated with QoL or clinical disease activity.

Conclusion

This study suggests the Eetscore is a useful tool to monitor and support a healthy diet in IBD patients. Diet quality improved significantly following personalised dietary advice of the Eetscore. Short term results did not indicate a correlation between diet quality and QoL or clinical disease activity.
