Agten, Christoph Amadeus; Margaroli, Lukas; Bensler, Susanne; Fritz, Benjamin; Rosskopf, Andrea B; Held, Ulrike; Pfirrmann, Christian W A (2018). Prevalence of vitamin D insufficiency in radiologists: a cross-sectional study. Skeletal Radiology, 47(7):981-988.

Abstract

OBJECTIVE To compare the prevalence of vitamin D insufficiency between radiologists and a control group of non-radiologists. MATERIALS AND METHODS This prospective cross-sectional study was conducted at the Swiss Congress of Radiology in May of 2016. Attendees (radiologists and non-radiologists) were asked to give a venous blood sample to measure vitamin D (25-hydroxyvitamin D) blood serum level. Vitamin D insufficiency was defined as < 50 nmol/l (30 ng/ml). We collected information on profession, age, gender, vitamin D supplements, recent sunny vacation, and eating fish. We compared vitamin D between radiologists and non-radiologists. RESULTS A total of 137 radiologists (mean age, 38 ± 10 years) and 164 non-radiologists (mean age, 40 ± 12 years) participated in the study. Prevalence of vitamin D insufficiency in both groups was similar (58.4% (80/137) vs. 53.7% (88/164); p = 0.240). Forty-three participants were under vitamin D supplementation. In those without supplementation, we found no difference in vitamin D between groups (44.0 ± 16.2 nmol/l (17.6 ± 6.5 ng/ml) vs. 44.4 ± 16.9 nmol/l (17.8 ± 6.8 ng/ml); p = 0.757). Average vitamin D levels for radiologists were slightly lower (-0.98 nmol/l (0.39 ng/ml), 95% confidence interval - 5.96 to 4.00 (- 2.38 to 1.6 ng/ml); p = 0.699), when adjusting for the potential confounders, but not statistically significant. The odds ratio of vitamin D insufficiency for radiologists versus non-radiologists was 1.7 (95% CI = 0.94-3.06; p = 0.078) after adjusting for the other independent variables. CONCLUSIONS The prevalence of vitamin D insufficiency in radiologists was high (58.4%), but not substantially higher than in non-radiologists.
