What this trial studies

This observational cohort study will enroll pregnant women in their first or early second trimester and follow them through delivery and one year postpartum. The study aims to collect detailed medical and obstetrical information, as well as biological samples, to understand the biological mechanisms leading to preterm delivery among Zambian women. Participants will receive standard care and education on nutrition and pregnancy health throughout the study. Regular study visits will be scheduled to monitor maternal and fetal health, and to screen for common pregnancy complications.

Who should consider this trial

Good fit: Ideal candidates are pregnant women aged 15 years and older, residing in Lusaka, with a singleton or twin pregnancy confirmed by ultrasound.

Not a fit: Patients who are HIV-infected or those who are beyond 24 weeks of gestation at enrollment will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new strategies for preventing preterm birth and improving maternal and infant health outcomes.

How similar studies have performed: Other studies have shown success in understanding preterm birth mechanisms, but this specific approach in Zambia is novel.
