ABSTRACT
OBJECTIVE: To determine the risk factors related to asymptomatic bacteriuria (ABU) in pregnant women. MATERIAL AND METHOD: Three hundred and sixty asymptomatic pregnant women who attended their first antenatal appointment at Rajavithi Hospital from August 1 and October 31 2005 were enrolled. Those with symptoms of urinary tract infection within one month, those who had been prescribed antibiotics during the previous seven days, and those with medical or obstetric complications, vaginal bleeding, and history of urinary tract disease were excluded. Urine specimens were collected by clean-catched midstream urine technique for culture. Several risk factors related to ABU and obstetric and demographic characteristics were recorded. RESULTS: The prevalence of ABU in pregnant women was 10.0%. The significant risk factors related to ABU in pregnancy was lower education level < or = grade 6 (p < 0.05) with 2.17-time risk of ABU compared with higher education level > grade 6. Maternal and gestational age, occupation, monthly income, gravidity, previous history of urinary tract infection and anemia were not statistically associated with ABU. CONCLUSION: Lower education level (< or = grade 6) should be the only significant risk factor related to ABU in Thai pregnant women under limited sample size.

OBJECTIVE: To evaluate the diagnostic performance of reagent strip test as a screening test for asymptomatic bacteriuria (ABU) in pregnant women. MATERIAL AND METHOD: Three hundred and sixty asymptomatic pregnant women who attended their first antenatal appointment at Rajavithi Hospital from August 1st to October 31st, 2005 were enrolled Those with symptoms of urinary tract infection within one month, those who had been prescribed antibiotics during the previous 7 days, and those with medical or obstetric complications, vaginal bleeding and a history of urinary tract diseases were excluded Urine specimens were collected by clean-catched midstream urine technique for urine dipstick and culture. RESULTS: The prevalence of ABU was 10.0% The urine dipstick nitrite leukocyte esterase and combined test had a sensitivity of 16.7%, 75.0% and 16.7%, specificity of 99.1%, 67.9% and 99.4%, positive predictive value of 66.7%, 20.6% and 75.0%, negative predictive value of 91.5, 96.1% and 91.5%, accuracy of 90.8%, 68.6% and 91.1%, respectively. CONCLUSION: Reagent strip testing indicated a fair sensitivity for routine antenatal screening for asymptomatic bacteriuria in pregnant women
