Temporal Patterns in Preterm Birth Subtypes and Perinatal Survival, 2000–2023: Population‐Based, Repeated Cross‐Sectional Time‐Series

Key Points

Perinatal survival improved even as preterm birth rates increased, underscoring a significant health trend.
The analysis from 2000-2023 highlights key changes in perinatal survival metrics within specific populations.
Population-based, repeated cross-sectional time-series methods were utilized to track changes in preterm birth subtypes.
Results suggest that categorizing preterm birth may better elucidate relevant health trends and challenges.

Abstract

Perinatal survival improved despite increasing PTB rates. The trend of PTB should be interpreted in the context of perinatal health indicators, and categorisation of PTB could aid with truly reflecting and explaining the trends and patterns of PTB within a population.
