[Current status and perspectives of obstetrics in China: an insight from evidence-based medicine].

Nationwide epidemiological data on pregnancy and childbirth was lacking in China during the last decades. Since the establishment of the national data monitoring network and the booming of regional epidemiological studies, more information has emerged. The results and suggestions from the China Labor and Delivery Survey are crucial for improving current clinical practices. Researches that are conducted based on national data monitoring network and hospital-based medical history system, and multicenter clinical trials will provide plenty of useful evidences. These high-quality evidences would further improve clinical practice and development of obstetrics in China.
