Abstract

Medical residents may be vulnerable to low vitamin D status because of long work hours and lack of sun exposure. We conducted a prospective cohort study to measure serum 25-hydroxyvitamin D concentrations among internal medicine residents, document seasonal variation in vitamin D status, and assess risk factors for inadequate vitamin D stores. Dietary intake of calcium and vitamin D, lifestyle characteristics, and serum concentrations of 25(OH)-vitamin D and intact parathyroid hormone (iPTH) were measured in 35 resident volunteers before and after the winter season. A total of 63-69% of medical residents consumed <400 IU/day of vitamin D; 61-67% consumed <1000 mg/day of calcium. Twenty-five (74%) had lower serum 25(OH)-vitamin D concentrations and 23 (68%) had higher serum iPTH in the spring than in the fall. Nine (26%) residents had serum concentrations of 25(OH)-vitamin D of
