Prematurity and Multidimensional Risk Patterns in Adolescent and Adult Pregnancies: A Principal Component Analysis in an Eastern European Cohort

Prematurity-related risk profiles were multidimensional and varied meaningfully by age and pregnancy outcome. These exploratory PCA-derived dimensions provide a data-driven framework for understanding how risk clusters across different maternal populations and may help generate hypotheses for age-specific preventive and clinical strategies. Confirmation and further validation in prospective, multicentre studies are required before clinical application.
