Differences in Dietary Patterns of Adolescent Patients with IBD

Inflammatory bowel disease (IBD) includes Crohn's disease (CD) and ulcerative colitis (UC). The prevalence of both in pediatric populations has been constantly increasing. This study aimed to analyze the diet of adolescent patients with IBD in comparison to healthy controls and the current dietary standards for the Polish population to further their optimal supplementation regimen. The study group consisted of 53 patients (21 girls and 32 boys) with IBD (CD: n = 27; UC: n = 26) at a mean age of 15.4 ± 2.4 and 14.7 ± 2.2, years for girls and boys, respectively. The control group (CG) consisted of 20 patients, and 72 h of recall diaries on nutrition were collected. The nutritional data were analyzed in the Dieta 6D dietary program. When compared to Polish dietary standards, the largest differences girls with IBD and boys with IBD were found for the intake of energy (61.9 and 71.9%), iodine (61.9 and 62.6%), folates (76.2 and 87.5%), vitamin D (100 and 96.9%), potassium (61.9 and 59.4%), and calcium (85.7 and 93.8%). The overconsumption of saturated fatty acids (SFA) (61.9 and 56.3%) and sodium (76.2 and 90.6%) in girls and boys, respectively, was noted. In relation to girls with CG, girls with IBD showed a significantly higher intake of energy (1751. 3 vs. 1558.6 p = 0.0224), total protein (71.3 vs. 56.2 p = 0.0217), animal protein (47.8 vs. 34.5 p = 0.0183), total carbohydrates (237.3 vs. 196.1 p = 0.0442), and assimilable carbohydrates (219.8 vs. 180.5 p = 0.7921). Boys in the CG consumed significantly more calcium (851.8 vs. 432 p = 0.0006), phosphorus (1024.3 vs. 1357.5 p = 0.0431), lactose (11.6 vs. 6.1 p = 0.0016), and riboflavin (1.7 vs. 1.3 p = 0.0123) compared to boys with IBD. Dietician care should therefore be mandatorily provided alongside outpatient care. Based on our results, we suggest that supplementation with the selected components be considered.
