Association of placental location and neonatal weight in subjects attending to hospitals of Azad University of Tehran in 2018-2019

Background: Fetal weight is a common index of health in neonates and determination of related factors would help to improve the conditions and outcomes. The aim of this study was to speculate the relationship between placental location and neonatal weight. Materials and methods: We conducted an observational-prospective study on 87 pregnant women. Placental position was categorised by ultrasonography as anterior, posterior and lateral position. Demographic information, including age, early pregnancy weight, weight in the last week of pregnancy, height, gravid, parity, history of underweight in previous pregnancies and history of underweight in the husband family, was recorded in the checklist. Association of placental location with neonatal weight was noted in three groups. Results: The highest birth weight was seen in cases with lateral placenta and the least weight was observed in anterior placenta cases and there was statistically significant association between placental location and neonatal weight. Conclusion: Totally, according to the obtained results, it may be conducted that there is significant association between placental location and neonatal weight and the least weight was observed in anterior placenta.
