INTRODUCTION: Treatment of celiac disease (CeD) requires a strict gluten-free diet (GFD). Adherence is difficult to assess and influenced by many factors. Identification of potential gluten exposures is essential, but no validated screening measures exist in pediatrics. The aim of this study was to develop and validate a measure screening for gluten exposure risk in pediatric patients with CeD. METHODS: The Gluten Exposure Risk Assessment (GERA) was developed in 3 phases. First, items were generated and refined by a modified Delphi process. Next, psychometrics, factor structure, and validity were examined in a sample of caregivers of pediatric patients younger than 18 years with CeD at 12 pediatric celiac centers. Finally, the final measure was tested on an independent sample population using confirmatory factor analysis and test-retest data. RESULTS: A total of 134 items were generated representing up to 6 domains, with 36 items selected for initial testing. Based on psychometrics and confirmatory factor analysis data from 484 caregivers, the final measure included a total of a single screening question and 9 validated items representing 2 domains (Home, Outside). Repeat testing on a separate sample (N = 369) confirmed factor structure and validity of the final measure (Comparative Fit Index = 0.96, Tucker–Lewis index = 0.95, root mean square error of approximation = 0.06). DISCUSSION: The GERA is a valid screening measure, completed by caregivers, for assessment of gluten exposure in children and adolescents with CeD following a GFD. GERA is a useful tool for evaluating the potential of risk of gluten exposure and potential need for intervention.

In response to the social inequities that exist in health care, the NIH-funded Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR) recently formed a diversity committee to examine systemic racism and implicit bias in the care and research of eosinophilic gastrointestinal diseases (EGIDs). Herein, we describe our process, highlighting milestones and issues addressed since the committee’s inception, which we hope will inspire other researchers to enhance diversity, equity, inclusion, and accessibility (DEIA) in their fields. Our journey began by establishing mission and vision statements to define the purpose of the committee. Regular discussion of diversity-related topics was incorporated into existing meetings and web-based materials were shared. This was followed by educational initiatives, including establishing a library of relevant publications and a speaker series to address DEIA topics. We then established a research agenda focused on the following actionable items: (1) to define what is known about the demographics of EGIDs by systematic review of population-based studies; (2) to develop a practical tool for reporting participant demographics to reduce bias in EGID literature; (3) to examine health disparities in the care of individuals with eosinophilic esophagitis who present to the emergency department with an esophageal food impaction; (4) to examine how access to a gastroenterologist affects the conclusions of published research examining the prevalence of pediatric eosinophilic esophagitis; and (5) to develop a model for examining the dimensions of diversity, and provide a framework for CEGIR’s ongoing projects and data capture. In addition to promoting consciousness of DEIA, this initiative has fostered inclusivity among CEGIR members and will continue to inspire positive changes in EGID care and research.
