Objective: To determine the effect of matemal anemia on placental ratio. Design: Cohort Study. Place and duration of study: Unit-1, Department of Gynaecology and Obstetrics 1, Sir Ganga Ram Hospital, Lahore from August 2002 to August 2003. Patients and the methods: One hundred pregnant women, 50 anemic and 50 having normal range of Hb were included in the study. After delivery, weight of the new bom and weight of placenta was recorded. The fetoplacental ratio was calculated for both groups and compared. Results: The mean weight of the newbom (±SD) in anemic group was 3.12 ± 0.45Kg and 3.18+0.35Kg in control group. The difference was statistically non-significant (P=0.445). The mean placental weight of anemic group was 0.58±0.13Kg and that of control group was 0.52±0.088Kg showing a significant increase (P<0.009). Feto-placental ratio was 0.193+0.035 (Mean±SD) in anemic patients and 0.166+0.024 in control group. FP ratio of anemic patients was significantly higher than control group (P<0.001). Conclusion: This study confirms that anemia during pregnancy is associated with significantly large placental weight and a high fetoplacental ratio.
