The goal of this nationwide multicenter observational study is to comprehensively investigate the severity of Small Vulnerable Newborns (SVN) issues across China and to propose further preventive and intervention measures. The primary aim is to provide a thorough description of SVN problems using a unified definition and framework, and to develop targeted prevention strategies.
Participating centers across the country will collect clinical data on vulnerable newborns under their care and complete detailed questionnaires to support this research.
