Understanding Premature Birth: Why It Affects so Many Women and How a New Test Can Help Identify a Patient's Risk
Sep 22, 2017 - 2:09:54 PM
Recent data released from the National Center for Health Statistics showed that the premature birth rate rose to 9.84 percent in 2016, up from 9.63 percent in 2015, marking the second consecutive increase after steady declines over the previous seven years. Given that an estimated 1 in 10 babies in the U.S. is born too soon, this data should be a compelling reminder for all healthcare providers that premature birth needs to be a top priority and point of discussion with their patients.
Women who’ve previously had a premature birth have the greatest risk of delivering early again. That said, approximately 40 percent of women who go on to have a premature baby are first time moms! There are common risk factors for premature birth, including: problems with the placenta, cervix or uterus, conceiving via In Vitro Fertilization (IVF), carrying multiples (more than one baby, i.e. twins or triplets), infections or other chronic health conditions like diabetes or high blood pressure, heightened stress or poor diet/nutrition. However, an estimated 50 percent of women who deliver early will not have any known risk factors.
In my practice, we screen for infection, measure cervical length, check vitamin D levels and
discuss with all patients the most common premature labor signs and symptoms that they should be aware of as they progress through their pregnancy, including: contractions that occur in 10-minute-or-less intervals, vaginal or fluid leakage from the vagina or cramping in the lower abdomen. However, if and when a woman is already experiencing any of these symptoms, it can be too late.
Fortunately, a new test recently became available for women that can help predict their individualized risk of delivering prematurely, very early into their pregnancy. The PreTRM® test is a blood test performed during the 19th or 20th week of pregnancy that analyzes specific proteins in the blood that have been shown to be accurate predictors of premature birth. The test is intended for asymptomatic women who are carrying one child (not twins or triplets).
This is a first-of-its-kind validated test to help provide doctors and their patients with a specific risk factor for delivering early. And although the test cannot prevent premature birth, it can provide helpful information for doctors. If a patient’s test result shows an increased risk, I can work with my patient to manage her risk with the goal of giving her baby the best start in life.
One of my patients, a 41-year-old mother-of-two expecting her third child, opted to take the PreTRM test. She experienced premature labor symptoms with her second pregnancy and was on bedrest for six weeks prior to delivery. As the sole income earner for her growing family, she knew that she could not risk the time or expense of having a baby in the NICU if she were to deliver early the third time around. Her test revealed she had a slightly elevated risk of delivering early and as a result, I was able to monitor her more closely and intervene with appropriate medical treatments as symptoms of premature labor began to appear later into her pregnancy. With these interventions and additional visits, she successfully delivered a healthy baby at term. Most importantly, it provided both me, and my patient with additional knowledge and guidance about the progression of her pregnancy.
There are so many variables during pregnancy and many unknowns for both the mother and her doctor. To that end, it is important to be aware of all options that can help make the entire pregnancy more predictable and enjoyable. This, in addition to leading a healthy lifestyle, obtaining adequate rest and staying on top of routine prenatal appointments, will ensure that babies have the best start in life. www.pretrm.com
