title: Risk factors related to asymptomatic bacteriuria in pregnant women.
abstract: OBJECTIVE
  To determine the risk factors related to asymptomatic bacteriuria (ABU) in pregnant women.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  Lower education level (< or = grade 6) should be the only significant risk factor related to ABU in Thai pregnant women under limited sample size.
