RESUMO
Background: because of increase in number of side effect that caused by hypovitaminosis D, this study has been done to find out prevalence of hypovitaminosis D in blood donors
Methods and Materials: in this Cross - sectional and descriptive study, we evaluated 183 persons, 163 male [89.07%] and 20 female [10.92%]. The average range of women and men was 17-52y and 17-53y respectively
Results: the results revealed that 8 persons [4.4%] had sever hypo vitaminosis D [vit<25 nmol/l]. 124 persons [67.8%]: mild hypovitaminosis D [vit D=25-62.4nmol/l], 45 persons [24.6%]: normal serum level of vit D [62.5-125 nmol/l] and 6 persons [3.3%] had hyper vitaminosis D [> 125 nmol/l]. Prevalence of hypocalcemia and hypophosphatemia in blood donors was 95 persons [51.9%] and 10 persons [5.5%] respectively. Also average serum level of PTH was 32.1 +/-33. 4 pg / ml
Conclusions: the above finding suggests a solid and effective programming for education of people about prevalence and complications of hypovitaminosis D, more effective screaming studies for improving knowledge of individual about prevalence of hypovitaminosis D and related disease in society and necessity of medical health personnel's knowledge about hypovitaminosis D
