N2 - Objective To examine prevalence of novel newborn types among 165 million livebirths 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 Liveborn infants Methods Country teams with high-quality data were invited to be part of the Vulnerable Newborn Measurement Collaboration. We classified livebirths by six newborn types based on gestational age information (preterm, PT, 90th centile) for gestational age, according to INTERGROWTH-21st standards. We considered small newborn types of any combination of preterm or SGA and Term+LGA was considered large. Time trends were analysed using three-year moving averages for small and large types.Main Outcome Measures Prevalence of six newborn types.Results We analysed 165,017,419 livebirths and the median prevalence of small types was 11.7% (highest in Malaysia (26%) and Qatar (15.7%)). Overall, 18.1% of newborns were large (T+LGA), and was highest in Estonia 28.8% and Denmark 25.9%. Time trends of small and large infants were relatively stable in most countries. Conclusions 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 in Europe. To better understand the global patterns of these novel newborn types, more information is needed especially from low- and middle- income countries.
