Summary Physicians are indoor workers with low sun exposure. The aim of this study was to compare serum 25-hydroxyvitamin D(25(OH)D) levels among hospitalists and community-based physicians. 25(OH)D levels among hospitalist physicians were significantly lower than those among community-based physicians. Hospitalist physicians should be considered for vitamin D deficiency screening and replacement. Introduction Vitamin D deficiency is now recognized as a widespread phenomenon, even in a sunny, Mediterranean country such as Israel. Physicians may be vulnerable to low vitamin D levels due to long work hours and lack of sun exposure. Methods Forty-three physicians employed in a hospital and 38 physicians who work in the community in Jerusalem were enrolled. Their serum 25(OH)D levels were measured, and a questionnaire was filled to assess the risk of vitamin D deficiency. Results Mean serum levels of 25(OH)D among hospitalist physicians were significantly lower than those among community-based physicians (15?±- vs. 19.7?±-?ng/ml, respectively; p-lt;-.00?l). Arab physicians had a lower 25(OH)D level compared to Jewish physicians (18.2?±-.6 vs. 11.4?±-.7?ng/ml; p-lt;-.001). After exclusion of Arab physicians from the analysis, 25(OH)D levels remained higher in hospitalist compared to community-based physicians (15.9?±- vs. 20.4?±-?ng/ml; p-lt;-.004). The variables that were significantly linked to low mean serum levels of 25(OH)D were as follows: age, night shifts, daily sun exposure, and ethnic origin. Conclusion Hospitalist physicians are at greater risk for low vitamin D levels than community-based physicians.
