A recent systematic review published by BioMed Central found that shift workers, healthcare workers and indoor workers were at the highest risk of developing vitamin D deficiency compared to other work environments.
Researchers compared the vitamin D levels of individuals from the following work environment categories: outdoor and indoor workers, shift workers, lead/smelter workers, coalminers and healthcare professionals. Using data from 71 peer-reviewed articles, they were able to determine average vitamin D levels of each work environment.
This is what the data revealed:
From their data collection, the researchers determined key groups to target for vitamin D deficiency.
The researchers concluded:
“Our review demonstrates that shift workers, healthcare workers and indoor workers are at high risk to develop vitamin D deficiency, which may reflect key lifestyle differences (e.g. sunlight exposure). This may help target health promotion and preventive efforts.”
