This transversal, observational, real-life study was effectuated on Caucasian Romanian females. A total of 60 subjects were grouped according to lumbar T-score: normal T-score (N=28), osteopenia (N=22), and osteoporosis (N=10). The lowest average value of 25OHD is found in patients with osteoporosis, which is statistically significant lower than in patients with osteopenia. The average values of PTH were within normal levels for each group. 25OHD did not correlate with PTH or lumbar BMD. Overall the mean values of 25OHD are in deficient ranges regardless osteoporosis, osteopenia or normal DXA.
