Objective To analyze the death status and main causes of death among children under 5 years old in Changsha from 2016 to 2021, and to provide a scientific basis for formulating preventive measures for children's health care. Methods The data of 1 761 deaths of children under 5 years old in Changsha City from 2016 to 2021 were collected, and the mortality trend, the order of causes of death and the utilization of pre-death medical care services were retrospectively analyzed. Results The 7-day neonatal mortality, 28-day neonatal mortality, 0-1-year-old neonatal mortality, and the mortality rate of children under 5 years old (U5MR) in Changsha City from 2016 to 2021 were 0.76‰, 1.28‰, 2.41‰, and 3.86‰, respectively. All the mortality rates showed a decreasing trend (P<0.05). U5MR in males was significantly higher than that in females (P<0.05), and U5MR in rural areas was significantly higher than that in urban areas (P<0.05). The top five causes of U5MR were drowning, premature delivery or low birth weight, pneumonia, other congenital anomalies, and accidental asphyxia, respectively. The death places of children under 5 years old were mainly medical and health institutions, and 81.72% of them were treated in hospitals before death. Conclusion From 2016 to 2021, the mortality rate of children under the age of 5 in Changsha City has gradually decreased. Preventing congenital malformations, reducing preterm birth or low birth weight, improving the treatment level of pneumonia, and preventing accidents such as drowning and accidental suffocation are the key to reducing the mortality rate of children under 5 years old.
