Beirne, A., McCarroll, K., Walsh, J. B., Casey, M., Laird, E., McNulty, H., et al. (2021). Vitamin D and Hospital Admission in Older Adults: A Prospective Association. Nutrients, 13(2), 616. https://doi.org/10.3390/nu13020616
This article investigates the link between serum vitamin D status and hospitalization, including emergency department attendance, hospital admission and length of stay, in 3093 Irish participants aged 60 years and older. It appeared that there was an inverse relationship between vitamin D status and hospitalization. Participants with vitamin D serum concentrations below 50 nmol/L were more likely to attend the emergency department and be admitted, and also to have an increased length of stay. This result was independent of markers of physical and cognitive vulnerability. It is suggested that there should be more attention for increasing serum vitamin D levels in older adults until at least 50 nmol/L. More research should be performed to validate this supplementation advice and to focus on randomised controlled trials.
