Abstract
Background
Inflammatory bowel disease (IBD) has a profound impact on psychosocial aspects of food and nutrition, thereby affecting food-related quality of life (QoL). While there is literature on associated prevalence of increased anxiety in individuals with IBD, there is limited data on its contribution to hypervigilance and orthorexia with food intake. Many patients with IBD have strong beliefs about dietary symptom triggers, which can lead to avoidance behaviors and decreased nutrient intake. This can exacerbate malnutrition and disordered eating, as well as increase disease-related stress and negatively impact coping. While there are validated scales evaluating anxiety-related, QoL-related and food-related behaviors in IBD, a combined screening tool to assess this comorbid axis is not well described.
Aims
To conduct a systematic review of existing literature in order to inform practice and facilitate development of an effective food-related hypervigilance and QoL evaluation in IBD patients
Methods
The literature was systematically searched through September 2019, using an electronic database querying Embase, PubMed, MEDLINE, Cochrane Library and PsycINFO. We searched original articles describing development, validation and measurement properties for screening tools on anxiety, QoL and food-related behaviors in IBD from 1975 to 2018. The primary outcome of interest was to evaluate the current measurements of the validated tools to identify whether a screening tool highlighting all above parameters exists for patients with IBD.
Results
Initial database search resulted in 5548 articles. After screening titles and abstracts, 168 were included. After full text review and deduplication, 23 validated scales were identified for use in IBD patients with respect to measuring anxiety, health-related QoL and food-related behaviors. There was substantial heterogeneity in IBD populations using the assessment tools (adult vs. pediatric, CD vs. UC, inpatient vs. outpatient). The breakdown of studies identified: 2 studies (8.6%) evaluated QoL and anxiety, 2 studies (8.6%) evaluated QoL and food-related behaviors. The remainder of studies individually assessed QoL, anxiety and food-related behaviors (47.8%, 26% and 8.6% respectively). None of the tools performed satisfactory to establish all three measurements in individuals with IBD.
Conclusions
Recent evidence suggests the presence of dietary hypervigilance in individuals with chronic GI conditions potentially leading to food restrictive behaviors impacting QoL. Screening models evaluating multivariable relations of anxiety in food-related behaviors and QoL in IBD is lacking. Efforts should be made to develop and validate a multi-assessment screening tool to aid in early identification of this prevalence in IBD patients to facilitate improved management outcomes.
