Area of Science:

  • Public Health Surveillance
  • Epidemiology
  • Genetics

Context:

  • Established in 1992, China's birth defect surveillance system monitors ~150,000 infants annually.
  • It was initially designed to evaluate folic acid's effectiveness in preventing neural tube defects.

Purpose:

  • To describe a unique birth defect surveillance system in the People's Republic of China.
  • To detail its methodology, data collection, and initial findings.

Summary:

  • The system collects detailed descriptions and photographs of infants with visible structural anomalies.
  • Between 1993-1996, over 1 million births were monitored, identifying >10,000 birth defects, including neural tube defects, oral clefts, and extremity abnormalities.

Impact:

  • Provides an extensive database for studying birth defect etiology, epidemiology, and trends.
  • Demonstrates a unique, advantageous system for birth defect monitoring in China.
