“…Studies pertaining to placental weight at term showed that placental weight varies from geographical location [3,4,10]. In this present study the mean placental weight was 652 ±152g and ranged from 250g to 1,200g.…”

“…The placental weights examination and measurement are of great clinical relevance and is associated with a wide range of unfavourable obstetric outcome and this study was aimed to determine the correlation between placental weight and foetal outcome. There are few documented local studies of placental weight and foetal outcome [1,3]. Though the pathogenesis of variability of placental size remains largely unclear, this study would provide information about the placental weight and its association with adverse obstetrics outcome in our locality.…”

“…The placental weight is about one sixth of the normal weight of the newborn [1]. Some studies have examined the relationship of placental size to the neonatal birth weight at term and concluded that placental weight was linked with pregnancy outcome [1,3]. Placentae vary in weight, size, thickness, form and consistency.…”

“…Recent studies on foetal birth weights show that foetal birth weights at term have increased over time [7,8]. There is a positive correlation between foetal weight and placental weights in some studies [1,3]. The placenta can be weighed with membranes and cord attached, but the standard approach is to weigh the placenta after the extra placental membranes and the umbilical cord are trimmed from the disk [1].…”

Background: Placenta is a vital feto-maternal organ for promoting pregnancy, foetal growth and development. Placenta varies in weight, size, thickness, form and consistency. The weight of the placenta is functionally significant because it is related to villous surface area and foetal metabolism. Gross examination of placenta after delivery may provide a useful insight into foetal weight, newborn and maternal complications of pregnancy. Objectives: To determine the mean placental weight in our environment and also, to determine the correlation between the placental weight and neonatal outcome in term pregnancies in Calabar. Materials and Methods: This was a cross-sectional study of 300 women conducted at University of Calabar Teaching Hospital (UCTH). Participants in the study were women with singleton pregnancies who delivered either by vaginal delivery or caesarean section at term. Examination and weighing of placenta were done at delivery for placental weight. Foetal outcome that were recorded included birth weight, sex, length of the newborn and Apgar score at 5th minute. Maternal age, marital status and parity were also obtained. Data obtained were analyzed using the statistical package for Social Sciences (SPSS) version 20. Level of significance was set at p-value less than 0.05. Data were presented in tables and graph. Results: The mean placental weight was 652 ±152g and ranged from 250g-1,200g. The mean foetal birth weight was 3.309 ±0.522kg and ranged from 2.0-5.9kg. The mean placental weight to birth weight ratio was 1: 5.08. The mean gestational age at delivery was 38.94 ±1.33weeks while the mean length of the neonate was 49.79 ±2.66cm. There was a corresponding increase in placental weight with increase in neonatal birth weight and length of the neonate. Conclusions: Placental weight was positively correlated with birth weight and length of the neonate. Critical examination and weighting of the placenta immediately after delivery should be done to determine the well being of the newborn.

“…Different studies have also shown an association between maternal weight and placenta weight. [20][21][22] Proper maternal nutrition facilitates proper growth and development of the placenta and ultimately the developing fetus. [23] In addition, there was a significant increase in placenta weight with maternal age in the univariable model.…”

Introduction: Placenta morphometry varies with increased heavy metal concentrations among other factors. There is limited knowledge on the effect of perceived heavy metal exposure due to mining activities on placenta morphometry specific to the Tanzanian population. The study thus aimed to determine the morphometric characteristics of the human placenta and the association between placental weight with maternal factors in mining and non-mining areas in Northwestern Tanzania. Subjects and Methods: This was a comparative cross-sectional study conducted in Mwanza and Geita regions of Northwestern Tanzania representing the mining and non-mining areas, respectively. Included in the study were placentas from 490 mothers, residing in the respective areas throughout pregnancy. Comparison of the placenta morphometric variables between the two groups was made using the independent sample t-test, and association between the maternal factors and placenta weight was done using multi-level linear analysis. Results: The mean placenta weight in the non-mining and mining areas was 465.9±101.2 g and 443.6±82.7g, and the mean thickness was 1.52±0.32cm and 1.61±0.38cm respectively. The mean diameter in the non-mining and mining areas was 19.0±1.9cm, the mean cotyledon number was 20±5 and 19±4, and the mean cord length was 49.0±12.7cm and 50.1 ±10.4cm respectively. With the exception of cord length, the differences in the morphometric parameters in the non-mining and mining areas were significant p<0.5. Increase in maternal weight on booking and maternal age were associated with corresponding increase in placenta weight. Conclusion: The findings of this study seem to suggest that heavy metal exposure due to mining activities does affect placenta growth.
