Prevalence of disordered eating in adults with gastrointestinal disorders: A systematic review.

BACKGROUND: Patients with gastrointestinal disorders are prone to heightened awareness of dietary intake. When diet-related thoughts or behaviors are excessive, they may lead to psychological distress, nutritional compromise, and impair medical treatment. Identification of disordered eating behavior and eating disorders is crucial for effective management, but data on their prevalence within this population remain scarce. We conducted a systematic review of the prevalence of disordered eating behavior and eating disorders in adults with gastrointestinal disorders. METHODS: MEDLINE, PubMed, and PsycInfo databases were searched up to June 2021. Studies examining disordered eating in adult patients with a primary gastrointestinal diagnosis were included. KEY RESULTS: A total of 17 studies met the inclusion criteria for the review. The range of gastrointestinal disorders examined included disorders of gut-brain interaction (DGBI), coeliac disease, and inflammatory bowel disease (IBD). The methods for examining disordered eating were highly variable. The prevalence of disordered eating ranged from 13-55%. The prevalence was higher in patients with disorders of gut-brain interaction (DGBI) than in those with organic gastrointestinal disorders. Factors associated with disordered eating included female sex, younger age, gastrointestinal symptom severity, anxiety and depression, and lower quality of life. CONCLUSIONS & INFERENCES: Disordered eating is highly prevalent in adult patients with gastrointestinal illness, particularly those with DGBI. Understanding whether a patient's primary underlying diagnosis is that of an eating disorder or gastroenterological disorder remains a challenge for clinicians. There is an unmet need to identify at-risk patients so that psychological intervention can be included in the therapeutic strategy.

Insulin pump therapy in children and adolescents: changes in dietary habits, composition and quality of life.

AIM: Continuous subcutaneous insulin infusion (CSII) can improve glycaemic control and dietary flexibility compared with conventional insulin therapies. There is little information on whether users are utilising this increased dietary flexibility, and whether dietary quality is affected. METHODS: A pre-post observational study was undertaken in 28 children and adolescents with type 1 diabetes commencing CSII. Meal pattern and dietary composition was examined from 3-day food diaries completed before and 3-6 months after CSII commencement. Participants completed the Diabetes-Specific Quality of Life for Youth Short Form, and body mass index z-score, and glycated haemoglobin were measured. A second posttest was undertaken at 18 months with those who were still on CSII and contactable (n = 18). RESULTS: Energy and macronutrient intake before and 18 months after CSII commencement were unchanged. Mean snacking events decreased significantly by 1.2 snacks per day (P = 0.009), as did the percentage energy derived from snacks (28.8%, 95% confidence interval (CI) 21.5-36.1 vs. 19.3%, 95% CI 13.2-25.4; P = 0.045). Diabetes-Specific Quality of Life for Youth Short Form score was not significantly affected by pump commencement (25.9 95% CI 18.2-33.6), and body mass index z-score remained similar before and after CSII. Glycated haemoglobin decreased by 0.5% in the 3-6 months following CSII commencement, but was similar to baseline at 18 months. CONCLUSIONS: This study demonstrates that the commencement of CSII did not lead to an abandonment of healthy eating principles, and that patients utilised the increased dietary flexibility to make changes to their snacking pattern.
