Pregnancy-Related STIs Increase Risks of Birth Complications: New Research
New research links sexually transmitted infections during pregnancy to higher risks of preterm birth, stillbirth, and small-for-gestational-age babies, highlighting the need for improved screening and healthcare access.
A comprehensive study conducted by Curtin University has identified a significant link between sexually transmitted infections (STIs) during pregnancy and increased likelihood of adverse birth outcomes. Analyzing nearly 60,000 births in Australia's Northern Territory from 2005 to 2020, researchers found that infections like syphilis, chlamydia, gonorrhea, and trichomoniasis are associated with serious complications such as preterm birth, stillbirth, and babies born smaller than expected. Notably, maternal syphilis tripled the risk of preterm delivery and more than doubled the risk of growth restriction in infants, while gonorrhea nearly doubled the chance of stillbirth.
Lead researcher Dr. Jennifer Dunne emphasized that these findings underscore the urgent need to enhance STI screening protocols throughout pregnancy, especially in high-risk areas. Current testing typically occurs early in pregnancy, but additional assessments later on could help prevent devastating outcomes. Many of these infections are preventable and treatable, reinforcing the importance of timely detection and intervention.
The study also highlights the public health challenges faced by remote communities, where access to healthcare services is often limited. Dr. Jacqui Hendriks pointed out that barriers to testing and treatment in isolated regions contribute to high STI rates, making culturally appropriate, accessible healthcare services essential. Strengthening follow-up care and raising awareness about STIs during pregnancy are crucial steps to improve maternal and infant health outcomes.
This research adds to the growing evidence that prioritizing STI prevention, screening, and treatment during pregnancy can significantly reduce adverse birth complications. It calls for healthcare systems to implement more comprehensive strategies, especially in remote and underserved regions, to protect mothers and their babies.
