OBJECTIVE - To study the prevalence of and risk factors for asymptomatic ba
cteriuria (ASB) in women with and without diabetes.
RESEARCH DESIGN AND METHODS - A total of 636 nonpregnant women with diabete
s (type 1 and type 2) who were 18-75 years of age and had no abnormalities
of the urinary tract, and 153 women without diabetes who were visiting the
eye and trauma outpatient clinic (control subjects) were included. We defin
ed ASB as the presence of at least 10(5) colony-forming units/ml of 1 or 2
bacterial species in a culture of clean-voided midstream urine From an indi
vidual without symptoms of a urinary tract infection (UTI).
RESULTS - The prevalence of ASB was 26% in the diabetic women and 6% in the
control subjects (P < 0.001). The prevalence of ASB in women with type 1 d
iabetes was 21%. Risk factors For ASB in type 1 diabetic women included a l
onger duration of diabetes. peripheral neuropathy, and macroalbuminuria. Th
e prevalence of ASB was 29%, in women with type 2 diabetes. Risk factors fo
r ASB in type 2 diabetic women included age, macroalbuminuria. a lower BMI.
and a UTI during the previous year. No association was evident between cur
rent HbA(1c) level and the presence of ASB.
CONCLUSIONS - The prevalence of ASB is increased in women with diabetes and
might he added to the list of diabetic complications in these women.
