Diagnostics and follow-up of celiac disease have gradually shifted from tertiary centers to secondary and primary health care. In order to establish whether this has affected the success of treatment, and to identify predictors for dietary non-adherence, we carried out a study in a nationwide cohort of treated celiac patients.


843 biopsy-proven patients, 94 children and 749 adults, were enrolled and interviewed. Adherence to a gluten-free diet was determined by means of an interview and serological testing.


Altogether, 88% were on a strict gluten-free diet; the rest had occasional dietary transgressions. Younger age at diagnosis, being currently a teenager, and current symptoms were associated with non-adherence. There was no association between non-adherence and place of diagnosis, gender, disease phenotype or severity of symptoms before diagnosis, presence of comorbidities, family history of celiac disease, smoking, duration of diet, use of oats, self-efficacy for the diet or lack of follow-up.


Good dietary adherence can be achieved also in patients diagnosed and followed in primary health care. In a country with a high prevalence and good general knowledge of celiac disease, only age at diagnosis and age at present would appear to be major determinants for adherence.
