Low levels of vitamin D linked to increased hospital visit and length of stay, not to mention the risk of Covid.
The health effects of vitamin D are well documented, with increasing evidence of its roles beyond bone health.
This study showed an inverse association between vitamin D and Emergency department (ED) attendance
Those admitted had lower mean vitamin D concentrations (58.4 vs. 69.3 nmol/L, p < 0.001).
Higher vitamin D was inversely associated with hospital admission and length of stay (LOS).
The study also showed independent prospective associations between vitamin D deficiency and increased hospitalisation by older adults
