Summary What is already known on this topic?A new conceptual term,small and vulnerable newborns(SVN),bringing preterm birth,small for gestational age(SGA),or low birth weight(LBW)together is being advocated for assessing whether a child is at high risk.What is added by this report?According to the new conceptual term,the increasing incidence of high-risk newborns(from 9.82%to 10.96%)has been observed among 2,005,408 newborns over the period from 2013 to 2022,which is higher than using any of the three definitions of SVN.Maternal age≥35,primiparity,and multiple births are high risks for SVN.What are the implications for public health practice?The new conceptual framework should be used to better assess the number of high-risk newborns.Attention should be paid to multiple births to prevent preterm-related SVN.To reduce term newborns who are SGA,we need to be concerned not only with multiple pregnancies but also with first-time mothers.
