The required data were collected and entered in SPSS software version 21.0 to be analyzed. A p-value less than 0.05 was considered as the significance level.
Results: Total individuals of 120 children (72 (60%)boys) with an average age of 46.77+40.5 months were selected for the investigation.Sixty-two patients(51.7%)of the children received an appropriate vitamin D supplement, and prevalence of vitamin D supplementation use was higher in case group(P=0.011).The average serum level of 25-hydroxyvitamin D in individuals was 31.36+19.01,and the average serum level of vitamin D in the patient group was greater than that of the control group(P=0.003).The frequency of 25-hydroxyvitamin D deficiency was higher in the control group(p=0.001).
