The Association of Serum 25-Hydroxyvitamin D Status in Patients with Osteoarthritis in the Primary Care Office.

Background: Low serum 25-hydroxyvitamin D [25(OH)D] and osteoarthritis (OA) are commonly found in patients followed up in a primary care office. Clear evidence to support the link between 25-hydroxyvitamin D levels and OA is lacking.

Aim: To describe the association of serum 25-hydroxyvitamin D status in patients with OA in the primary care office.
