In 2009, the Global Alliance to Prevent Prematurity and Stillbirth Conference charged the authors to propose a new comprehensive, consistent, and uniform classification system for preterm birth. This first article reviews issues related to measurement of gestational age, clinical vs etiologic phenotypes, inclusion vs exclusion of multifetal and stillborn infants, and separation vs combination of pathways to preterm birth. The second article proposes answers to the questions raised here, and the third demonstrates how the proposed system might work in practice.
2009 年，全球预防早产和死产联盟会议责成作者提出一种新的全面、一致和统一的早产分类系统。本文首先回顾了与胎龄测量、临床表型与病因表型、多胎和死胎婴儿的纳入与排除以及早产途径的分离与结合相关的问题。第二篇文章提出了对这里提出的问题的答案，第三篇文章展示了所提出的系统如何在实践中发挥作用。
