    Abstract:
    The strict nature of a gluten-free diet (GFD) poses a challenge for patient adherence and for clinicians to provide comprehensive client-centered care. Evidence on the relationship between nutrition knowledge, food skills, dietary management, and adherence can guide healthcare professionals counseling patients following this diet. In this explanatory pilot study, a province-wide survey (phase I) with 68 community-dwelling Nova Scotians following a GFD was conducted to investigate relationships between personal, social, and health care factors and dietary adherence using a mixed-methods approach. A sub-sample of 19 survey respondents were interviewed (phase II) to explore contextual experiences related to GFD knowledge, food skills, dietary management, and adherence using a food literacy lens. Here, we report findings from phase I, in which 37 participants with self-reported celiac disease (CD) and 31 participants reporting non-celiac reasons for wheat restriction (NCWR) completed a detailed 41-item online questionnaire. Self-reported data combined for both CD and NCWR respondents showed 76% perceived their health status as good to excellent. Most (62%) reported not receiving GFD advice from a health professional. Respondents with higher frequency of intentional consumption of gluten were more likely to have fewer correct answers to a food label quiz (ρ = -0.44; P = .0002). Most participants (75%) made at least one error in identifying gluten-free and gluten-containing foods, which may lead to unintentional gluten consumption and/or unnecessarily restricting safe foods. Findings from this exploratory study suggest patients may lack adequate referrals and support within the health care system and the community, adding to individual challenges of GFD adherence.
