Evaluation of 25- hydroxy Vitamin D Blood Levels in Patients with Musculoskeletal Pain

Low blood levels of vitamin D in different communities is common. In this study، we evaluated the blood levels of 25-hydroxy vitamin D in patients presented with musculoskeletal pain. Evaluation of 25- hydroxy Vitamin D Blood Levels in Patients with Musculoskeletal Pain In a descriptive study، blood levels of vitamin D in 358 patients with musculoskeletal pain، that presented to the orthopedic clinic of Poorsina Hospital of Rasht during 2007-2008 years، were measured by serum levels of 25- hydroxy vitamin D using Radio Immunoassay (RIA). Normal range of vitamin D in this study، was 32 -100 ngr/milt. Amounts between 15 -32 ngr/milt، was introduced as mild vitamin D deficiency and amounts lower than 15 ngr/milt as severe vitamin D deficiency. Normal range of vitamin D was seen in 65 cases (16. 68%)، severe vitamin D deficiency in 182 cases (51. 96%) and mild vitamin D deficiency in 107 cases (29. 89%). Average serum levels of vitamin D among all cases، was 20. 1ngr/milt. Severe vitamin D deficiency belong to the patients with musculoskeletal pain in the ages younger than 20 years، compared to other ages and only 4% of them had normal range of this vitamin. Given vitamin D severe deficiency in (51. 96%)، i. e.، majority of cases who were studied، there seems to be a significant association between vitamin D levels and risk of musculoskeletal disorders.
