the frequency of bacteriuria and its relationship with demographic characters in pregnant women of gilan, 2009-11

background:  approximately 80 to 90 percent of women will experience a urinary tract infection at least once in their lifetime. 2 to 11 of them, in first pregnancy trimester are affected, which, if untreated, leads to the maternal and fetal risks. screening for urinary infection, is considered part of prenatal care. the purpose of this study was to determine the frequency of bacteriuria in pregnant women and their relationships with certain demographic variables. methods: this cross-sectional study was done on 710 pregnant women who referred to health centers of gilan. for data collection, the forms were completed based on information in their case and urine culture test requested by the health centers on the first trimester. for statistical analysis, spss/ver19, t-tests and chi square were used. results: the mean age of subjects was 27/48± 6/02. frequency of bacteriuria in this study was %21/1. statistically significant correlation were demonstrated between the variables mean age (p=0.002), parity (p=0.001), educational level (p=0.001), occupation (p=0.001) and education with the wife (p=0.001) having bacteriuria, so these variables had positive roles in the prevalence of bacteriuria, but between variables such as abortions, occupation, average age and type of delivery, pregnancy termination no statistically significant relationship was found. conclusion: considering the high frequency of bacteriuria in this study and their complications which are created for pregnant women, further investigation to determine possible causes and the species causing it, seems to be a necessity.
