Progesterone and Preterm Birth: Using Empirical Research to Explore Structural Racism Within Midwifery-Led Care.

BACKGROUND: Progesterone has been the standard of practice for the prevention of preterm birth for decades. The drug received expedited Food and Drug Administration approval, prior to the robust demonstration of scientific efficacy. METHODS: Prospective research from the American Association of Birth Centers Perinatal Data Registry, 2007-2020. Two-tailed t tests, logistic regression, and propensity score matching were used. RESULTS: Midwifery-led care was underutilized by groups most at risk for preterm birth and was shown to be effective at maintaining low preterm birth rates. The model did not demonstrate reliable access to progesterone. People of color are most at risk of preterm birth, yet were least likely to receiving progesterone treatment. Progesterone was not demonstrated to be effective at decreasing preterm birth when comparing the childbearing people with a history of preterm birth who used the medication and those who did not within this sample. CONCLUSIONS: This study adds to the body of research that demonstrates midwifery-led care and low preterm birth rates. The ineffectiveness of progesterone in the prevention of preterm birth among people at risk was demonstrated.

Freestanding Birth Centers: An Evidence-Based Option for Birth.

Every childbearing person has the right to learn about all options for perinatal care provider and birth setting. To ensure an informed decision about their preferred birth plan, information should be provided either preconceptionally or in early pregnancy. Personal preferences and risk status should be considered in decision-making. Numbers of births in birth centers have doubled over past decade to almost 20,000 births per year. The evidence shows that childbearing people who participate in birth center care, even if they have only birth center prenatal care, experience better outcomes including lower rates of preterm birth, low birth weight births, and cesarean birth, and higher rates of breastfeeding when compared to people with similar risk profiles who receive typical perinatal care.
