Abstract : Background: In general, no study has examined the relationship between vitamin D status and key parameters of bone mineral homeostasis in healthy men in Iran. The effects of age and renal function on vitamin D status were determined in a cross-sectional study on a healthy population of Iranian men.Methods: From January through February 2001, 520 men, aged 20 ع 74 years were selected through a cluster randomized sampling from Shiraz. Serum 25-hydroxyvitamin D, intact parathyroid hormone, calcium, phosphorus, alkaline phosphatase, creatinine, and albumin were measured. Pearson and partial correlation coefficients were used to determine the association between variables.Results: Five hundred twenty men with a mean▒آSD age of 45▒آ15 years and a mean▒آSD 25-hydroxyvitamin D level of 35▒آ17 nmol/L were enrolled into the study. Over 33.9percent of men in Shiraz had a low level of 25-hydroxyvitamin D )آذ25 nmol/L(. Serum 25-hydroxyvitamin D did not decline with age in men. Serum parathyroid hormone increased significantly by age in men, but it did not correlate with the decline in creatinine clearance. Men had a decline in serum phosphorus )r=0.23, P<0.0001( and calcium )r=0.14, P=0.001( concentrations by age. Creatinine clearance declined with age.Conclusion: In healthy men, the serum level of 25-hydroxyvitamin D did not decline with age. Nonetheless, the prevalence of vitamin D deficiency is high which warrants consideration of dietary vitamin D supplement in men.
