Background: Vitamin D deficiency or insufficiency is a highly prevalent condition worldwide. Anesthesia providers or support personnel working in operating rooms might be considered at increased risk of vitamin D deficiency. There is a small amount of information about 25(OH)D levels in people who work mainly indoors as an operating room. This study aimed to investigate whether there was a higher vitamin D insufficiency or deficiency rate among anesthesia personnel working indoors when compared with personnel working in an office or outdoors in Ankara, Turkey (39 North, 32 East).
