Diabetic people in low-income neighborhoods in California were up to 10 times more likely to lose a leg or a foot than diabetic patients in wealthier ZIP Codes, UCLA researchers have reported.

Their analysis, published online Monday by the journal Health Affairs, pinpointed amputation "hot spots" where as many as 10.7 out of 1,000 diabetic adults ages 45 and older wound up losing a lower limb because of complications of diabetes.
