Introduction:

Celiac disease (CD) causes intestinal damage, inability to absorb nutrients, and progressive malnutrition. Iron deficiency is one of the predominant nutritional problems. A strict gluten-free diet (GF) allows for an optimal quality of life.

Objective: To assess the nutritional situation of iron in school-aged celiac children by determining biochemical parameters, their relation to the consumption of the mineral and adherence to gluten-free diets in San Luis.

Methods:

Observational, analytical and cross-sectional study. We included 44 children with CD, from 6-10 years of age, with diagnosis of celiac disease and registered in public and private entities of San Luis (Argentina) during 2011-2012. A qualitative-quantitative survey was used to determine dietary habits and sociodemographic characteristics. Iron levels and adherence to a GF diet were evaluated. Generalized linear regression models were constructed to verify the association of ferritin with iron consumption and adherence to diet.

Results:

Most families had low socioeconomic status and were large families. Current feeding did not prevent iron deficiency anemia. Most children had normal immune system, and normal antiendomysial and antitransglutaminase antibodies; 7% of the children showed low levels of iron. Under adequate iron consumption conditions, ferritin was associated to predictor antibodies and the presence of both parents in the home.

Conclusion:

Under adequate conditions of iron consumption, the levels of iron in blood were related to adherence to gluten-free diets.
