[The analysis on the change and trend of the congenital heart disease mortality rate in children aged 0-1 in China from 2004 to 2018].

To analyze the trend of the congenital heart disease mortality rate in children aged under 1 year old from 2004 to 2018. The mortality rate and constituent ratio of congenital heart disease in different genders, urban and rural areas and regions were calculated by using the publicly available Dataset of National Mortality Surveillance in China from 2004 to 2018. The Joinpoint regression model was used to analyze the changing trend of mortality rate and constituent ratio, and calculate the annual percentage change (APC) in each time period, the average annual percentage change (AAPC) in all time period and their 95% values. From 2004 to 2018, a total of 15 969 children aged 0 to 1 years died of congenital heart disease, of which 58.12% (9 281) were boys and 71.79% (11 464) were in rural areas. The deaths of congenital heart disease in eastern, central and western regions accounted for 34.30%, 37.06% and 28.64% of total deaths, respectively. From 2004 to 2018, the mortality rate of congenital heart disease in children decreased from 106.81 per 100 000 to 38.70 per 100 000, with an AAPC (95%) about -7.2% (-11.5%, -2.6%). The mortality rate of congenital heart disease showed a downward trend in girls [AAPC (95%) =-7.7% (-13.0%, -2.0%)], boys [AAPC (95%)=-6.8% (-12.0%, -1.2%)], urban areas [AAPC (95%) =-5.9% (-9.9%, -1.7%)], rural areas [AAPC (95%) =-7.4% (-10.5%, -4.2%)], eastern region [AAPC (95%)=-8.6% (-14.2%, -2.6%)], and central region [AAPC (95%)=-7.8% (-11.5%, -4.0%)]. The gaps of mortality rate gradually shrank in different genders, urban and rural areas and regions. From 2004 to 2018, the constituent ratio of congenital heart disease in children showed an upward trend [AAPC (95%) = 3.3% (1.7%, 4.9%)]. From 2004 to 2018, the mortality rate of congenital heart disease in children aged 0 to 1 years showed a downward trend, and the constituent ratio showed an upward trend.
