DWM VIT D DEFY X STROKE

Vitamin D Status and Risk of Stroke

Stroke: A Journal of Cerebral Circulation

TAKE-HOME MESSAGE

• Adults aged ≥45 years were followed to evaluate the association between vitamin D levels and the risk of stroke. Serum 25-hydroxyvitamin D concentration was associated with prevalent stroke. After exclusion of patients with prevalent stroke, only severe vitamin D deficiency was associated with the risk of incident stroke.

• Severe vitamin D deficiency was associated with incident stroke. Lower vitamin D levels among individuals with prevalent stroke may be a consequence of stroke rather than being a causative factor.
