study of vitamin d level in children with non-specific musculoskeletal pain

backgroundvitamin d deficiency is known as a one of the underlying causes of idiopathic musculoskeletal pain (imsp). this study aimed to evaluate the correlation between serum vitamin d (cholecalciferol) status in patient with non-specific musculoskeletal pain and healthy children.materials and methodsseventy-seven children (aged 3–14 years), with imsp were included as cases and 90 healthy subjects were selected for control group. demographic characteristics and biochemical levels of vitamin d and parathyroid hormone (pth), were obtained. data were analysis using spss version 17.0 software.resultsresults showed that vitamin d means levels of patients and healthy children were significantly different (19.5 + 8.84 ng/ml versus 12.7 + 11.89 ng/ml), respectively (p<0.05). also, there was a significant difference between pth level in both healthy and patient subjects (p<0.001). mean levels of vitamin d in both groups were below the normal range, but lower in control group (p<0.001).conclusiondeficiency of vitamin d was suggested as the probable identified risk factors for imsp in children. the results of our study did not reveal clear correlation between vitamin d deficiencies in children which suffer imsp compared the healthy children.
