Background: To reveal the ethnic disparity in the pneumonia-specific mortality rates of children under the age of five years(PU5MRs) and provide suggestions regarding priority interventions to reduce preventable under-five-years-of-age deaths. Methods: Data were obtained from the Direct Report System of Maternal and Child Health in Sichuan. The Cochran-Armitage trend test was used to assess the time trend. The Cochran-Mantel-Haenszel test and Chi-square test were used to examine the differences in the PU5MRs among different groups. Results: The PU5MRs in the minority and nonminority counties decreased by 53.7% and 42.3% from 2010 to 2017, respectively. The PU5MRs of the minority counties were 4.81 times higher than those of the nonminority counties in 2017. The proportion of pneumonia deaths to total deaths in Sichuan Province increased from 11.7% in 2010 to 15.5% in 2017. The pneumonia-specific mortality rates of children in the categories of 0-28 days, 29days-11 months, and 12-59 months were reduced by 55.1%, 38.8%, and 65.5%, respectively, in the minority counties and by 35.5%, 43.1%, and 43.7%, respectively, in the nonminority counties. Conclusions: PU5MRs declined in Sichuan, especially in the minority counties, while ethnic disparity still exists. Although the PU5MRs decreased more for the minority counties as a fraction of all mortality the absolute number of such deaths were higher, and therefore more children in these counties continue to die from pneumonia than from the non-minority counties. Priority should be given to strategies for preventing and controlling child pneumonia, especially for postneonates, in the minority counties.
