In this study 1500 pregnant women were evaluated. The mean of age was 28.4±6.1 year and mean of hemoglobin was 12.43±0.89 mg/dl. 107 subjects (7.1%) had hemoglobin less than 11 mg/dl. No significant relationship were seen between anemia and gravidity (p=0.905) and number of parity (p=0.432). 114 subjects (7.6%) had positive urine culture. There was seen a significant relationship between urinary tract infection and anemia (p<0.001). No significant relationship was seen between results of urine culture and parity and gravidity.
