P1247 An argument for screening? Disordered eating patterns are highly prevalent in Inflammatory Bowel Disease (IBD)

Résumé fourni par la source

Abstract Background The complex relationship between body image perception, disordered eating behaviours, and quality of life (QoL) has been poorly examined in patients with IBD. Although individuals with chronic gastrointestinal conditions are at an increased risk for disordered eating behaviours, the prevalence and risk factors associated with these attitudes remain underexplored in IBD. Therefore, this study aimed to investigate the relationship between IBD activity, body image perception, and disordered eating behaviours to determine clinical features that impact patient QoL. Methods An online questionnaire was administered through a tertiary centre IBD clinic in South Australia. Disordered eating behaviours were assessed via the validated Eating Disorder Examination-Questionnaire (EDE-Q7). Clinically significant eating disorder attitude is defined as EDE-Q7 score >3.5. Univariate and multivariate logistic regression analyses were performed to correlate clinically significant disordered eating behaviours with patient sex, disease activity, and the presence of clinical depression or anxiety. Results In a cohort of 210 respondents, clinically significant disordered eating behaviours were observed in 33.2% of respondents. Higher global EDE-Q7 scores were significantly associated with female sex (P<0.0001), active IBD (P=0.0169), and clinical depression (P<0.0001) and anxiety (P<0.0001). High global dietary restraint, shape/weight overevaluation, and body dissatisfaction subscores were significantly associated with female sex (P=0.0063; P=0.0001; P<0.0001), patients with clinical depression (P=0.0142; P<0.0001; P<0.0001), and patients with clinical anxiety (P=0.0003; P<0.0001; P<0.0001). IBD activity and Crohn’s disease were significantly associated with high global shape/weight overevaluation subscores (P=0.0216; P=0.0175) and body dissatisfaction subscores (P=0.0063;P=0.0117). Furthermore, clinically significant disordered eating behaviours were significantly associated with IBD activity (OR, 2.2; 95% CI, 1.3-4.0; P=0.007), clinical anxiety (OR, 7.7; 95% CI, 4.0-14.7; P<0.0001) and clinical depression (OR, 4.6; 95% CI, 2.4-8.7; P<0.0001). Multivariate regression analysis showed that the odds of high global EDE-Q7 scores are significantly increased by clinical anxiety (OR, 8.9; 95% CI, 4.3-18.4; P<0.0001). Conclusion This study demonstrates that disordered eating behaviours are highly prevalent in patients with IBD. Collectively, these findings provide important insight into the eating and body image behaviours that impact the QoL of patients with IBD.
