Does your job affect your vitamin D status? Should certain occupations have specific guidelines and actions to take for vitamin D?
A review by Sowah et al. looked at data from 71 peer-reviewed studies to determine how vitamin D levels differed among individuals working in different occupations. The review included indoor and outdoor workers, shift workers, lead/smelter workers, coalminers, and healthcare professionals. The authors also evaluated the effect of season on vitamin D levels between the different groups.
For the purpose of this study, vitamin D deficiency was defined as a 25(OH)D level below 20 ng/ml (50 mol/L), and insufficiency was defined as a level between 20-30 ng/ml (50-75 nmol/L).
