Understanding Preterm Birth Risks: A Guide for Expecting Mothers

Preterm birth, defined as delivery before 37 weeks of pregnancy, impacts approximately 10% of pregnancies in the United States, making it one of the most prevalent complications during pregnancy. This issue often remains under the radar, leaving many expectant mothers unaware of their own risk profiles until complications arise. According to Dr. Thaïs Aliabadi, a certified OB-GYN based in Los Angeles and a co-host of the SHE MD podcast, it’s crucial that mothers understand their individual risks for preterm birth—a process that can start as early as week 18 of their pregnancy.

What is Preterm Birth?

Preterm birth occurs before the 37-week mark and is a leading cause of health complications and fatalities in newborns. Research suggests that early intervention is key to managing this risk effectively. Unfortunately, many doctors rely on traditional methods for assessing risk, which typically identify only 20% of at-risk women based on their medical history. This is particularly challenging for first-time mothers, who often lack previous pregnancy data.

Dr. Aliabadi champions a proactive approach to understanding preterm birth risk through a novel blood test called the PreTRM® Test, designed to predict individual risk by measuring specific biomarkers in a woman’s blood.

The PreTRM® Test Explained

The PreTRM® Test is a breakthrough in prenatal care, offering the only broadly validated blood-based biomarker test to assess a woman’s risk of spontaneous preterm birth in asymptomatic singleton pregnancies. This test is conducted between weeks 18 to 21 and evaluates the protein ratio of IBP4 and SHBG, which correlates strongly with the likelihood of preterm birth.

By utilizing this test, doctors can plan and implement preventative measures much earlier in the pregnancy timeline. In fact, findings from the PRIME trial, which included around 5,000 participants, revealed that utilizing this test could reduce preterm births before 32 weeks by over 50%, significantly lowering the risk of NICU admissions.

Importance of the 18 to 21-Week Window

Dr. Aliabadi emphasizes the importance of screening within this critical window: "For many years, the approach to determining preterm birth risk has been reactive rather than proactive, especially for first-time mothers who might not have medical histories to reference. Discovering individual risk early allows for timely intervention, which can effectively alter outcomes for both mothers and newborns."

This shift from a reactionary stance to a preventative one can lead to fewer complications in the NICU and healthier babies. By having informed discussions with healthcare providers about testing options in this time frame, mothers can become advocates for their own health and the health of their future children.

What Can Be Done Following Risk Identification?

Once a potential risk is identified, physicians can take several low-cost, evidence-based actions derived from the PRIME trial. Key tactics include:

• - Administration of vaginal progesterone
• - Use of low-dose aspirin
• - More frequent check-ins with nursing staff

These steps have collectively shown to significantly reduce the incidence of preterm births and subsequent admissions to neonatal intensive care units. As reported, with effective implementation of these strategies nationwide, an estimate suggests a potential reduction of approximately 94,300 NICU admissions annually in the U.S.

Wrapping Up

Dr. Aliabadi’s commitment to preventative care shines through her advocacy for early testing and proactive health measures. "Every pregnant woman deserves the opportunity to know her risks and make informed choices based on that information. The PreTRM® Test is a vital tool in changing the preterm birth narrative and supports a healthier future for both mothers and their babies."

The SHE MD podcast, founded alongside fellow advocate Mary Alice Haney, continually seeks to empower women with vital health information. By stressing the importance of conversations with healthcare providers, SHE MD enables women to take charge of their prenatal care. Ultimately, the goal is to ensure that no woman enters pregnancy uninformed about potential risks and the ways to mitigate them.

By understanding and addressing preterm birth, we can shift from a narrative of fear to one of control and proactive care. You can stay informed about your own pregnancy and advocate effectively by discussing the PreTRM® Test with your healthcare provider at your upcoming check-up.
