Niveles de vitamina D en médicos: ¿son los anestesiólogos el único grupo de riesgo?

Resumen

Background: Sun exposure is the main source of 25-hydroxy-vitamin D. Since anesthesiologists work inside operating rooms, they are identified as a deficiency risk group. As medical activity in general occurs indoors, added to the work excess and sedentary lifestyle, physicians in general have low sun exposure. Aim: To investigate the determinants of vitamin D levels in physicians. Material and methods: Anesthesiologists and physicians not working in operating rooms were included. A survey that comprised working hours, diet, skin color, sunscreen use and outdoor activities was also applied. Measurements of vitamin D and parathormone levels in blood were performed. Results: We analyzed samples from 81 volunteers. Median vitamin D vales of the whole sample were in the range of insufficiency (25.3 [interquartile range 12.4] ng/ml). Multiple linear regression analysis detected no differences between anesthesiologists and non-anesthesiologists. A higher body mass index was a risk factor for vitamin D deficiency, (p=0.025). The only protective factor was the intake of a vitamin D supplement (p<0.01). Conclusions: Anesthesiologists and other specialists were both at risk for vitamin D deficiency. Obesity was a risk factor and the use of a vitamin D supplement was the only protective factor.
