What this trial studies

The ChiTwiMC cohort is a multicenter prospective study focusing on the complications associated with twin pregnancies in China. It aims to establish a large mother-child cohort that follows participants from pregnancy through early childhood, collecting extensive data on maternal and neonatal outcomes. The study will recruit 2000 pregnant women aged 18-45 years from nine major university-affiliated hospitals, with data collection occurring at various stages of pregnancy and after delivery. Biological samples will also be collected to investigate adverse outcomes related to twin pregnancies.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18-45 years who are expecting twins and are less than 14 weeks pregnant.

Not a fit: Patients with serious maternal illnesses or mental disorders that prevent participation will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve understanding and management of complications in twin pregnancies, leading to better maternal and neonatal health outcomes.

How similar studies have performed: While there have been studies on twin pregnancies, this specific multicenter approach with a comprehensive biobank is relatively novel.
