Low Dietary Vitamin D Predicts 34-Year Incident Stroke

Background and Purpose—Vitamin D deficiency has been reported to contribute to the risk of cardiovascular disease, especially stroke. We examined the relationship between dietary vitamin D intake and 34-year incident stroke.

Dietary vitamin D intake was calculated using the Nutritionist IV Version 3 software from a 24-hour dietary recall. Subjects with prevalent stroke were excluded, leaving 7385 men followed through 1999 for incident stroke. Subjects were divided into quartiles of dietary vitamin D for analyses. Read More
