From a 1999 article in the Canadian Medical Association Journal, by Dr. Adeera Levin, Associate Professor of Medicine and Program Director of Nephrology at Univ. of British Colombia -
"There is at present an imbalance between men and women in the population of patients with end stage renal disease in Canada: the current ration of men to women is 60:40. In contrast, US dialysis registry data indicate that men and women are more equally represented in that country."
here's the link if you want to read the doc's theories on why the imbalance exists -

If you google "dialysis statistics" you can find lots of info on ESRD patients. Global Dialysis estimates 1.5 million worldwide - over 308,000 in the US alone.
