Infant, Neonatal, and Post-neonatal Mortality in Greece: A Nationwide Time-Trend Analysis

Abstract

Introduction: Infant mortality is a crucial perinatal measure and is also regarded as an important public health indicator. This study aimed to comprehensively present time trends in infant, neonatal, and postneonatal mortality in Greece.Methods: The annual infant mortality rate (IMR), the neonatal mortality rate (NMR), and the post-neonatal mortality rate (PNMR) were calculated based on official national data obtained from the Hellenic Statistical Authority, spanning 67 years from 1956 to 2022. The time trends of the mortality rates were evaluated using joinpoint regression analysis, and the annual percent changes (APC) and the overall average annual percent change (AAPC) were calculated with a 95% confidence interval (95% CI).
