Study summary

Background: Excess weight and obesity are a global pandemic, particularly among women of childbearing age. Pre-pregnancy obesity is linked to adverse maternal and neonatal outcomes, including preterm birth, macrosomia, stillbirth, and neonatal death. These risks vary by maternal age, race, and ethnicity, with rising rates among immigrant and minority women. This study investigates overweight and obesity rates in pregnant women, weight gain during pregnancy, and adherence to guidelines and possible neonatal outcomes, comparing Turkish and Syrian immigrant women.

Methods: This retrospective single-center study was conducted at Buca Seyfi Demirsoy Teaching and Research Hospital in Izmir, Turkey, over one year. Data collected included demographic information, pregnancy complications, delivery modes, maternal and neonatal anthropometric measurements, and neonatal morbidity and mortality. The study included Turkish and Syrian women with complete medical records. Statistical analyses were performed using SPSS software, with significance set at p \< 0.05.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 6, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
