The group with celiac disease had a significantly lower mean BMI standard deviation score (SDS) than that of a control group of 22 age and sex-matched children with diabetes who did not have celiac disease. The mean height SDS and C-peptide levels in the two groups were similar, while the mean HbA-1-c was lower (better) in the group with celiac disease. After one year on a gluten-free diet the group with celiac disease improved its mean BMI score to that of the control group, and its HbA-1-c score went down (improved), while the control groups HbA-1-c score increased (worsened).
The researchers conclude that more studies are needed to support their findings that a gluten-free diet significantly improves glycemic control in children with type 1 diabetes and celiac disease.
