Aims: Short stature in children can occur in two stages before birth (embryonic stage) and after birth or in both stages. During pregnancy, the mother plays an important role in this regard. Instrument & Methods: This descriptive-analytic study was conducted during 2018 with participation of 122 children with type 2 diabetes. Sampling by non-probable and ready-made method was conducted by examining the records of patients with diabetes referring to the office of the physicians of the children of Tabriz University of Medical Sciences.Data were analyzed in SPSS 21 software.Pearson correlation test was used to analyze the data. Findings: The mean serum calcium level was 9.45±0.85mg/dl and the average serum levels of vitamin D were 10.99±1.14ng/ml. Serum vitamin D levels were divided into three levels of severe deficiency, mild and natural deficiency. Body mass index and diabetes time based on vitamin D and calcium group showed a significant difference between groups. Conclusion: The role of several micronutrients in ensuring adequate growth in children is well known. But it is not yet clear which of them has the greatest impact on children's developmental delay.
