Abstract

Background and aims: This study aimed to determine the prevalence of urinary tract infection (UTI)
among the pregnant women and the risk factors related to it in Shahrekord, Iran.
Methods: In this cross-sectional study, 832 patients were examined during 26 to 30 weeks of pregnancy
and their UTIs were studied. The required information was collected by examining the personal
pregnancy health records and completion of the data registration forms. All statistical analyses were
performed in SPSS software version 23.0 using chi-square and independent t test.
Results: According to the results of this study, out of 832 pregnant women, 109 were diagnosed with
UTI; hence the prevalence of UTI was recorded to be 13.1% in this study. Moreover, there was a
significant relationship between UTI and variables of delivery, severe nausea and vomiting during
pregnancy (known as morning sickness), genitourinary disorders, infertility, and blood group.
Conclusion: According to the study results, it seems that screening and treatment of UTIs have been
done appropriately and in the right time, in health systems of the city of Shahrekord which have led
to the reduction of disorders in infants, as well as maternal diseases. Even in the absence of any UTIrelated
symptoms, screening tests for UTI are recommended.
