Official title: Screening and treatment for Chlamydia trachomatis infection to prevent preterm birth

Funded at University of California, San Diego · NIH-11617691 · Data updated 2026-11-12

This grant studies whether screening pregnant people for Chlamydia trachomatis and treating those who are positive can reduce the risk of preterm birth.

Who could benefit from this research

Could help

Pregnant individuals in LMIC settings (and populations similar to those studied in Botswana) who are screened for CT during antenatal care.

Less likely to help

Pregnant individuals without CT infection or who do not access antenatal care may not directly benefit.

What this research studies

Chlamydia trachomatis infection during pregnancy is common and can contribute to preterm birth and other problems for the baby. The project builds on prior Botswana findings showing that screening asymptomatic pregnant people is feasible and may lower infection rates, aiming to determine the effect on birth outcomes through a larger trial. Researchers plan to implement screening and timely treatment in a real-world setting, using a rigorous design to measure impact on preterm birth and related outcomes. The study is focused on improving maternal and infant health in LMIC contexts and could inform future screening guidelines if successful.

Why it matters

Potential benefit: If successful, the approach could reduce preterm births and improve infant health by identifying and treating asymptomatic CT infections during pregnancy.

How similar studies have gone: Prior small studies showed screening is feasible and potentially reduces post-birth CT prevalence, but larger trials are needed to confirm birth outcome benefits.
