Prostate Cancer-Obesity Link Stronger in Blacks

"The study's primary author, Wendy E. Barrington, PhD, of the University of Washington School of Nursing and the Fred Hutchinson Cancer Research Center in Seattle, and colleagues found that among AA men a body mass index (BMI) of 35 kg/m2 or higher increased risk of low-grade PCa by 122% and increased risk of high-grade PCa by 81% compared to a BMI less than 25 which is considered normal weight. Among NHW men, having a BMI of 35 kg/m2 or higher was associated with a 20% reduced risk of low-grade and only a 33% increased risk of high-grade PCa compared to being of normal weight,. Compared with normal weight NHW men, AA men with a BMI less than 25, 25.0 to less than 27.5, 27.5 to less than 30.0, 30 to less than 35.5, and 35.0–50.0 had a significant 28%, 49%, 58%, 75%, and 103% increased risk of PCa, respectively, the researchers reported online in JAMA Oncology."
