BACKGROUND: Injuries are of growing public health concern in China, and the trends of urban-rural injury mortality disparity for the last decade are still being explored. This study aims to analyze trends in injury mortality disparity between urban and rural areas of China by region, sex, and age from 2010 to 2016.
METHODS: Using data from the Disease Surveillance Points system (DSPs) collected by the Chinese Center for Disease Control and Prevention (CDC) from 2010 to 2016, injury age-standardized mortality rates (ASMRs) and rate ratios (RRs) were calculated for different groups. Chi-square tests were used to compare differences in rates between urban and rural residents. The time trends of injury ASMRs were assessed via the annual percentage change (APC), and RRs were used to analyze urban-rural mortality disparity.
RESULTS: The crude injury mortality rate of rural areas was 1.5 times higher than that of urban areas. The urban-rural RR of injury ASMR decreased from 1.8 to 1.5 (APC = 5.0%) over time, from 2.0 to 1.7 (APC = 4.7%) for eastern regions, from 1.9 to 1.5 (APC = 5.4%) and from 1.6 to 1.3 (APC = 4.5%) among males and females, respectively. Further decreases were from 2.0 to 1.4 (APC = 7.8%), from 1.9 to 1.6 (APC = 6.4%), and from 1.8 to 1.2 (APC = 5.7%) in the 5-14, 45-64, and 65+ year age groups, respectively. The urban-rural RRs of ASMRs for fall, drowning and suicide decreased from 1.3 to 1.2 (APC = - 3.0%), from 2.3 to 1.6 (APC = - 13.8%) and from 2.1 to 1.6 (APC = - 9.9%,), respectively.
CONCLUSIONS: The urban-rural injury mortality disparity was large, but showed a significant decreasing trend in China. Residents of eastern regions, males/females, 5-14/45+ year age groups in the urban-rural injury mortality disparity all decreased gradually during the investigated period.
