Chronic Illness Linked to Preterm Birth
Pre-existing chronic health conditions are a major driver of adverse birth outcomes, according to a new cohort study from Ghana. The research found that 31.2% of postpartum women had conditions like hypertension or diabetes, which significantly increased their risk of preterm birth and low birth weight. The findings highlight persistent gaps in prenatal risk identification and management.
In the United States, about 1 in 10 infants is born preterm, defined as before 37 weeks of gestation. Chronic health conditions, which affect up to one-third of women of reproductive age, are a significant contributor to this statistic. Conditions like hypertension, diabetes, and heart disease can increase the risk of both spontaneous and medically indicated preterm birth. The U.S. preterm birth rate rose 12% between 2014 and 2022. Stark racial and ethnic disparities persist; in 2022, the preterm birth rate for Black women was 14.6%, approximately 50% higher than the rate for white women (9.4%). Black women are also five times more likely than white women to have a recurrent preterm birth. A Michigan Medicine study analyzing 8.2 million deliveries found that the detection of at least one chronic condition increased by nearly 40% between 2005-2006 and 2013-2014. The highest prevalence of these conditions was identified among vulnerable populations, including those in rural areas and the poorest communities. Preterm birth is a leading cause of infant death in the U.S. and is associated with long-term health problems for the baby, including cerebral palsy, asthma, vision and hearing problems, and developmental disabilities. These infants often require specialized care in a neonatal intensive care unit (NICU) after birth. Certified nurse-midwives (CNMs) are increasingly part of collaborative care teams that manage high-risk pregnancies, including those complicated by chronic illness. In these models, midwives provide continuous monitoring, patient education, and emotional support while working alongside obstetricians and maternal-fetal medicine specialists. In Virginia, regulations require licensed midwives to screen for pre-existing conditions at the initiation of care. If risk factors like chronic hypertension or a seizure disorder requiring medication are present, the midwife must disclose the risks of an out-of-hospital birth and provide options for physician consultation and referral. Digital health platforms are emerging as key tools for managing chronic conditions during pregnancy. Remote patient monitoring allows for at-home tracking of blood pressure, weight, and glucose levels, enabling earlier detection of complications, while telehealth provides access to specialists for patients in rural or underserved areas. The American College of Nurse-Midwives (ACNM) aims to expand the midwifery workforce to increase access to care and help reduce maternal mortality and morbidity. However, barriers such as restrictive state practice laws and shortages of clinical preceptors for students hinder the growth needed to meet rising demand.
