Urine albumin to creatinine ratio-response to exercise in diabetes

Abstract

Albuminuria was studied in 40 diabetic children before and after a standardised exercise test, and also in 21 normal children; the results are expressed as geometric mean (95% range) of urine albumin:urine creatinine ratio (mg/mg). There was no significant difference between the mean resting albumin:creatinine ratio in the two groups, or between these ratios before and after exercise in the normal children. In the diabetic children, however, the mean urine albumin:creatinine ratio after exercise was significantly higher than both the value before exercise and the postexercise value of the normal children, with 10 of 40 diabetic children showing a value after exercise greater than the 95% range of the geometric mean of the control group.
