Key Takeaways
- Preterm birth is estimated to account for 35% of perinatal deaths worldwide, measuring its share across stillbirth and neonatal outcomes
- In 2019, preterm birth complications accounted for 1.3 million deaths for children and another 0.8 million deaths among those aged 5–14 due to preterm complications over the life course (global estimate), quantifying the extended impact
- In the US, the preterm birth rate declined from 9.57% in 2007 to 9.62% in 2019, indicating a near-stable national trend over that period
- 5–18% of maternal infections during pregnancy are associated with preterm birth, indicating a measurable fraction of preterm births linked to infection exposure
- Multiple gestations increase the risk of preterm birth by about 4 times compared with singleton pregnancies, quantifying the effect of plurality on timing of birth
- 37.4% of preterm births in the US are associated with medically indicated preterm delivery (rather than spontaneous), quantifying the share of iatrogenic/indicated prematurity
- In the UK, 7.5% of live births were preterm in 2019, quantifying incidence in a national dataset
- Preterm birth is associated with a 20–30% increased risk of cerebral palsy compared with term birth, quantifying neurologic sequela risk
- Extremely preterm birth (22–27 weeks) increases the risk of severe visual impairment by about 2 orders of magnitude versus term-born infants, quantifying relative risk scale
- About 40% of surviving very preterm infants have at least one neurodevelopmental impairment by early childhood, measuring the prevalence of functional sequelae
- In the US, the average hospitalization for a preterm infant in 2008 costs about $58,500 (inflation not specified in-source), measuring the per-stay economic burden
- The lifetime cost to society of a single preterm birth in the US is estimated at about $26,000 (2011 dollars), quantifying per-case lifetime impact
- In a cohort study, each additional day of hospitalization in a NICU is associated with increased total costs, and NICU cost-to-charge ratios show substantial daily spending (unit economics), quantifying care intensity
- A systematic review estimates antenatal corticosteroids reduce the risk of respiratory distress syndrome by about 34%, quantifying one key short-term benefit
- Magnesium sulfate given to women at risk of imminent preterm birth reduces the risk of cerebral palsy by about 30% (meta-analysis), quantifying neurologic benefit
Preterm birth affects millions and drives major lifelong health and economic burdens despite preventive care advances.
