Vulnerable newborn types: Analysis of population‐based registries for 165 million births in 23 countries, 2000–2021

Abstract

The distribution of newborn types varies across the 23 middle- and high-income countries. Small newborn types were highest in west Asian countries and large types were highest in Europe. To better understand the global patterns of these novel newborn types, more information is needed, especially from low- and middle-income countries.
