简要总结
The aim of this prospective longitudinal study was to investigate the relationship between placental thickness during the second and third trimesters and placental and birth weights.
详细描述
The investigator will make certain that the appropriate informed consent process is in place to ensure that potential research subjects, or their authorized representatives, are fully informed about the nature and objectives of the study, the potential risk and benefits of study participation, and their right as research subjects.
All laboratory specimens, evaluation forms, reports, video recordings, and other records that leave the site will not include unique personal data to maintain subject confidentiality.
All patients provided an informed written consent after they were fully instructed about the investigation.The study was approved by ethical committee of Ain Shams University.
All recruited women were observed at the 1st trimester screening at antenatal clinic and assessed for baseline demographic and obstetric data including age, parity, body mass index (BMI) and past medical events. Smoking, alcohol and drug use were also determined.
At second and third trimester (15-20 and 30-34 weeks of gestation respectively), the maternal weight, weight gain, BMI, BMI gain and data of ultrasound examination were recorded. At the time of delivery after assessment of maternal weight as mentioned above, the birth weight (in grams), fetal sex, and mode of delivery were taken.
