Introduction Urinary tract infection is reported to affect 2 to 10% of all pregnancies. It is associated with maternal and neonatal complication including premature labor, premature rupture of membranes, low birth weight, intrauterine growth restriction, high perinatal mortality, maternal anemia, maternal and neonatal sepsis, arterial hypertension and renal failure. Objectives: To describe the prevalence of urinary tract infection, to identify etiologic agents and to describe the risk factors amongst pregnant women attending to a high risk antenatal clinic in Serra, Espiríto Santo. Methodology: Cross-sectional study of parturient women giving birth at Hospital Dr Dório Silva Maternity in the period between march 2010 and February 2011. The study collected information using face to face interviews including socio-demographics, epidemiologic and clinical data. The data collected included age, years of schooling, marital status, dwelling place, profession, number of pregnancies and abortions, type of delivery, gestational age and any previous history of urinary tract infection. A sample of urine was also collected and submitted to test1, urine culture and test sensibility antibiotic. Descriptive statistics analysis was performed. Any possible association between urinary tract infection and independent variables were tested using chi-square test with Yates correction or Fisher s exact test. Odds ratio and confidence intervals were calculated and a multivariate logistic regression analysis was used. Results: From 324 pregnant women identified, 305 (94.1%) took part in the study. The prevalence of urinary tract infection amongst the participants was 15.1% (CI 95% 11.0%-19.1%). The median age was 25 (DIQ 20; 30), years of schooling was 9 years (DIQ 7; 11). Fifty nine pregnant women (19.0%) were under 20, twenty eight (9.2%) had up to 4 years of formal education, two hundred and fifty five (83.6%) were married and one hundred and fifty five (50.8%) had a family income of less than 2 minimum wage. One hundred and twenty five (41.0%) were primigravidae, one hundred and seventy three (56.9%) were under 35 weeks when hospitalized and seventy five (24.6%) delivered low birth weight babies. Amongst the morbidities in the study 14.1% presented pre-eclampsy and 6.2% diabetes mellitus. Amongst the forty six cases of urinary tract infection, we identified twenty six with abnormal examination of urine sediment, with twenty three cases presenting pyuria. Four tests returned positive nitrite and twenty six tests presented increased bacterial flora. The agent isolated more frequently in the culture was Escherichia coli (52%), followed by Klebsiella sp. (15.2 %). Conclusion: The prevalence of urinary tract infections amongst the pregnant women cared for in the high risk maternity in Serra was high. These results corroborate the importance of screening for urinary tract infection during pregnancy in order to avoid complications during gestation and childbirth
