[Concentration of 25-hydroxyvitamin D in postmenopausal women with low bone mineral density].

Objectives: This study was designed to determine mean serum concentrations of 25-hydroxyvitamin D (25OHD) in postmenopausal women with low bone mineral density (BMD), to find the cutoff of parathormone (PTH) elevation, and to evaluate the correlation 25OHD with BMD, biochemical parameters and vertebral fracture presence.

Methods: Transversal study, with collection of 25OHD and PTH, and determination of DMO and column radiograph.

Results: A high incidence of inadequate serum concentrations of 25OHD (68.
