Kim HS, et al. - In this study, researchers examined demographics, lifestyle patterns, and clinical features of people with celiac disease (CD) and people without CD avoiding gluten (PWAG), defined as adherent to a gluten-free diet without a CD diagnosis, in order to better understand associations with medical conditions and consumer behavior. Among 22,277 members in the National Health and Nutrition Examination Survey 2009-2014, individuals with CD were identified by testing CD serology or by both a health care provider diagnosis and adherence to a gluten-free diet. During grocery shopping, participants with CD considered nutrition very important and tended to have more constipation and thyroid disease. Data reported that PWAG tended to spend more money on groceries, buy organic foods, and check food labels more frequently during grocery shopping. More food allergies, asthma, and thyroid disease have also been reported. The investigation confirmed that CD and PWAG share comorbidities of autoimmune nature. Findings suggested that PWAG experienced more autoimmune/allergy-related disorders that could be linked to non-celiac gluten sensitivity as a self-justifiable reason for dieting.
