A study of 602 Korean men with lower urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia found that those with a waist circumference greater than 90 cm (central obesity) had a 36% increased risk of severe LUTS compared with men who had smaller waists.

In addition, in men with central obesity, prostate volume correlated positively with urgency and nocturia.

Findings appear in the Asian Journal of Andrology (2009; published online ahead of print).
