Expanded health data from the new birth certificate, 2005

Area of Science:

• Perinatal epidemiology
• Public health surveillance
• Maternal and child health

Background:

• The 2003 U.S. Standard Certificate of Live Birth introduced new data fields for pregnancy risk factors, obstetric procedures, and newborn conditions.
• Understanding these updated data is crucial for monitoring maternal and infant health trends.

Purpose of the Study:

• To present 2005 data from the updated U.S. Standard Certificate of Live Birth, focusing on new and modified checkbox items.
• To analyze trends in risk factors, obstetric procedures, and newborn conditions, including congenital anomalies.

Main Methods:

• Descriptive tabulations of birth data from 12 states that implemented the 2003 certificate by January 1, 2005.
• Analysis of data on maternal conditions (e.g., diabetes), labor and delivery characteristics, and infant outcomes.

Main Results:

• Infants of mothers with prepregnancy diabetes had higher rates of high birthweight and neonatal intensive care unit (NICU) admission.
• Cervical cerclage was more common in multiple births; nearly all forceps/vacuum deliveries were successful, and one-third of cesarean deliveries involved a trial of labor.
• Congenital anomalies like cyanotic congenital heart disease and hypospadias were frequently reported, with notable racial and ethnic disparities in steroid and surfactant therapy use.

Conclusions:

• The 2003 U.S. Standard Certificate of Live Birth provides valuable data on contemporary obstetric practices and infant health.
• Findings highlight the impact of maternal diabetes on infant outcomes and disparities in care, underscoring the need for targeted interventions.
