Due to its importance in pregnancy, this study aimed to evaluate the frequency and related factors of bacterial vaginosis in pregnant women with gestational age less than 20 weeks.  Matherials & Methods: A total of 198 pregnant women with gestational age less than 20 weeks were enrolled in the study in Motahhari Hospital, Urmia. Information related factors were collected by interviewing the pregnant woman. Using Nugent’s criteria, patients were divided to three groups, positive, negative, and intermediate and were compared based on related factors.  Results: According to Nugent’s criteria, 151 patients with score less than 4 were negative (76. 26. %), 23 patients with score 4-6 were intermediate (11. 61%), 24 patients with score more than 6 were positive (12. 12%). There was no significant difference in age, BMI (Body Mass Index), Sexual behavior, educational level, and parity between the three groups. Patients with bacterial vaginosis used IUD significantly higher than negative group and none of them used condom as a contraceptive. There was a significant relation between vaginosis and type of pregnancy prevention (p=0. 01).  Conclusion: Our results showed the prevalence of bacterial vaginosis was 12.12% in this area with intermediate level of infection. Type of contraception method is possibly correlated with bacterial vaginosis in pregnancy.
