Post-term pregnancies risk infant's life and health, UCSF studies show

Two new studies by UCSF researchers found that infants born past 40 weeks of gestation are at higher risk for impaired health and death. The studies, which analyzed over 2.5 million births, confirmed the increased risk of cesarean deliveries and poor maternal or child outcomes as early as 40 weeks.
