Abstract

Neonatal encephalopathy (NE) due to birth asphyxia and trauma has become the second leading cause of global neonatal and under-5 deaths. However, comprehensive data on the global NE burden are scarce. This study aimed to determine the global, regional, and national trends in NE burden from 1990 to 2019, utilizing the 2019 Global Burden of Disease (GBD) study data.
Annual incident cases, deaths, disability-adjusted life years (DALYs), and age-standardized rates (incidence [ASIR], mortality [ASMR], DALYs) of NE were collected from the 2019 GBD study. The percentage of relative changes and estimated annual percentage changes (EAPCs) were calculated to assess temporal trends.
NE global incident cases increased from 1.33 million in 1990 to 1.38 million in 2019, with a 4.87% rise in ASIR. Global NE deaths remained at 0.57 million in 2019, despite a 29.88% reduction from 1990. Significant annual reductions in ASMR and DALYs were observed post-2005. South Asia and sub-Saharan Africa accounted for 80.00% of global NE cases, with South Asia, Eastern and Western sub-Saharan Africa contributing to 81.42% of global deaths and 79.50% of DALYs. NE-related deaths comprised 22.76% and 11.24% of neonatal and under-5 mortality. There were 3.91 million epilepsy, 4.23 million developmental intellectual disability, and 0.57 million blindness cases caused by NE globally in 2019.
Despite a significant reduction in NE mortality from 1990 to 2019, the ongoing rise in incidence, particularly in South Asia and sub-Saharan Africa, is alarming. Targeted initiatives to prevent NE are needed, especially tailored to high-burden regions.
