Asymptomatic bacteriuria and hemoglobin A1
JK Schmitt, CJ Fawcett and G Gullickson
We measured hemoglobin A1 (HbA1) and performed clean-catch urine cultures
in 752 patients (411 men and 341 women) with non-insulin-dependent diabetes
mellitus (NIDDM) attending an outpatient diabetes clinic. Prevalence of
bacteriuria was significantly greater in diabetic women than in controls
(9.1 vs. 5.0%, P less than .001) but not in diabetic men. Risk of
bacteriuria was not related to level of HbA1 at the time of urine culture.
However, mean duration of diabetes mellitus was significantly greater in
diabetic women with bacteriuria than in those without infection (9.9 +/-
1.5 vs. 5.4 +/- 0.4 yr, P less than .025), and the prevalence of
bacteriuria was significantly greater in patients with complications of
long-standing diabetes mellitus than in those without complications (P less
than .005).
