Introduction:China has made remarkable achievements in reducing infant deaths over the past 30 years.Meanwhile,the trend and cause composition of infant deaths have significantly changed,and the high-level years of life lost(YLLs)presents challenges to public health.This study analyzes the temporal trend and cause of infant mortality burden in China from 1990 to 2019.Methods:Based on the updated estimates from the 2019 Global Burden of Disease Study,we used death and YLLs to describe the infant mortality burden.The percentage changes were applied to illustrate the temporal variation over the period 1990-2019.Results:In 2019,the estimated infant deaths and YLLs in China were 101.9(95%uncertainty interval:88.6-116.4)thousand and 9.0(7.9-10.3)million,respectively,which decreased by 89.9%compared with 1990.Most infant deaths occurred in the neonatal period,especially the first 7 days of life.China’s infant mortality rates for all causes decreased from 1990 to 2019,whereas certain preventable causes such as preterm birth and congenital heart anomalies accounted for increasing proportions during this period.Conclusion and Implications for Public Health Practice:The present study reveals the major preventable causes of infant deaths in China.Decreasing neonatal mortality and improving health status of children at early stage of life have great significance on public health.This is also a solution to achieve the goal of“ending preventable child deaths”of the 2030 Sustainable Development Agenda.
