Vitamin D Levels and Related Genetic Polymorphisms, Sun Exposure, Skin Color, and Risk of Aggressive Prostate Cancer
Abstract
We have been collecting more participants from the participating sites with funding from Dr. Kittles laboratory. Preliminary findings showed that the rates of vitamin D deficiency with prospective specimen collection are 76% of all men. Rates of vitamin D deficiency were approximately 45% of European American men in Chicago and 86-95% of African American men depending on which deficiency cutoff definition used. The most predictive factor for being vitamin D deficient was season of the blood draw. Additionally, dietary intake of vitamin D was less than 200IU per day and the majority was not taking vitamin D supplementation. The mean vitamin D levels are lowest in African American men followed by Hispanic men, whom were also more deficient than European American men.
