Northwestern University Study Finds Vitamin D Deficiency in Black Men

A new study by researchers at the Feinberg School of Medicine at Northwestern University in Chicago finds that African-American men are 3.5 times as likely as white men to have vitamin D deficiency. Vitamin D deficiency has been linked to diseases such as prostate cancer, diabetes, multiple sclerosis, and rheumatoid arthritis.

Adam Murphy, a clinical instructor in urology at Northwestern, states that “it takes a dark-skinned male 90 minutes three times a week to absorb enough sunlight to produce the recommended amount of vitamin D compared to 15 minutes three times a week for a Caucasian male.

Dr. Murphy, who completed his medical training at the University of Chicago, presented the research at a recent conference of the American Association of Cancer Researchers in Washington.
