Self-Reported Prevalence of Gluten-Related Disorders and Adherence to Gluten-Free Diet in Colombian Adult Population

الملخص EN

Background.

Celiac disease seems to be rare in Colombians, but there are currently no data about the prevalence rates of symptomatic adverse reactions to gluten or adherence to gluten-free diet (GFD) in this population.

Aim.

to evaluate the self-reported prevalence rates of adverse reactions to gluten, adherence to GFD, and gluten-related disorders at population level in Colombia.

Methods.

A self-administered questionnaire-based cross-sectional study was conducted in a population from Northwest Colombia.

Results.

The estimated prevalence rates were (95% CI) 7.9% (6.5–9.6) and 5.3% (4.1–6.7) for adverse and recurrent adverse reactions to wheat/gluten, respectively, adherence to GFD 5.9% (4.7–7.4), wheat allergy 0.74% (0.3–1.4), and nonceliac gluten sensitivity 4.5% (3.5–5.8).

There were no self-reported cases of celiac disease.

Prevalence of self-reported physician-diagnosis of gluten-related disorders was 0.41% (0.17–0.96).

Most respondents reported adherence to GFD without a physician-diagnosis of gluten-related disorders (97.2%).

The proportion of gluten avoiders was 17.2% (15.2–19.5).

Most of them did not report recurrent adverse reactions to wheat/gluten (87.0%).

Conclusions.

Nonceliac gluten sensitivity is rarely formally diagnosed in Colombia, but this population has the highest prevalence rate of adherence to GFD reported to date.

Consequently, most respondents were avoiding wheat- and/or gluten-based products for reasons other than health-related symptoms.
