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

ABSTRACT:

Objective

To examine the prevalence of novel newborn types among 165 million live births in 23 countries from 2000 to 2021.

Design

Population-based, multi-country analysis.

Setting

National data systems in 23 middle- and high-income countries.

Population

Methods

Country teams with high-quality data were invited to be part of the Vulnerable Newborn Measurement Collaboration. We classified live births by six newborn types based on gestational age information (preterm <37 weeks versus term ≥37 weeks) and size for gestational age defined as small (SGA, <10th centile), appropriate (10th-90th centiles), or large (LGA, >90th centile) for gestational age, according to INTERGROWTH-21st standards.
