Eligibility

Age
7 Years to 16 Years

Inclusion criteria

Inclusion criteria: Age between 7 and 16 years;diagnosis of type 1 diabetes for at least 1 year

Exclusion criteria

Exclusion criteria: Other autoimmune diseases; sickle cell anemia; kidney or liver disease; genetic syndromes; intestinal malabsorption or hemoglobinopathies; use drugs that affect the metabolism of vitamin D, corticosteroids and insulin pump; and have recently supplemented with vitamin D.

Design outcomes

Primary

MeasureTime frame
Evaluate the glycemic control verified according to the value of HbA1c (%), before and after supplementation with vitamin D and it will be considered a good glycemic control, when the value of HbA1c is less than 7.5%.

Secondary

MeasureTime frame
It is expected to detect a minimum difference of 15% between two proportions (prevalence of the outcome adequacy of glycemic control - before and after the intervention), using the HbA1c value. The adequacy of vitamin D levels, in the form of 25-OHD, will be obtained by radioimmunoassay by the RIA and DiaSorin kits, using the serum stored in a freezer at -700C. Based on the results found, the study participants will be classified with DVD when 25 (OH) D is less than 30 ng / mL.
