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.
关于该主题已知的信息有哪些？：一个新的概念术语，即小而脆弱的新生儿（SVN），将早产、小于胎龄儿（SGA）或低出生体重儿（LBW）合并在一起，正被倡导用于评估儿童是否处于高风险状态。
本报告新增了哪些内容？：根据这个新的概念术语，在2013年至2022年期间对2005408名新生儿进行观察发现，高危新生儿的发病率在上升（从9.82%升至10.96%），这一发病率高于使用SVN的三种定义中的任何一种时的发病率。母亲年龄≥35岁、初产和多胎妊娠是SVN的高风险因素。
对公共卫生实践有哪些启示？：应使用新的概念框架来更好地评估高危新生儿的数量。应关注多胎妊娠以预防与早产相关的SVN。为了减少足月SGA新生儿的数量，我们不仅需要关注多胎妊娠，还需要关注初产妇。
