Abstract
BackgroundTo examine trends in unintentional falls mortality from 2006 to 2016 in China by location (urban/rural), sex, age group and mechanism.MethodsMortality data were retrieved from the National Disease Surveillance Points system (DSPs) of China, a nationally representative data source. Percent change in mortality between 2006 and 2016 was calculated as “mortality rate ratio - 1” based on a negative binomial regression model.ResultsThe crude unintentional falls mortality was 9.55 per 100 000 population in 2016. From 2006 to 2016, the age-adjusted unintentional falls mortality increased by 5% (95% confidence interval (CI) = 1%-9%), rising from 7.65 to 8.03 per 100 000 population. Males, rural residents and older age groups consistently had higher falls mortality rates than females, urban residents and younger age groups. Falls on the same level from slipping, tripping and stumbling (W01) was the most common mechanisms of falls mortality, accounting for 29% of total mortality.ConclusionsUnintentional falls continued to be a major cause of death in China from 2006 to 2016. Empirically-supported interventions should be implemented to reduce unintentional falls mortality.

Summary
Mortality data were retrieved from the National Disease Surveillance Points system (DSPs) of China, a nationally representative data source. Mortality data were retrieved from the DSPs, a nationally representative death registration system that was expanded between 2004 and 2006 to include 161 surveillance points (64 urban, 97 rural) across all 31 Chinese provinces [13,14]. A standardized and validated web-based approach has been used to report death cases in the DSPs since 2008 [15]. The DSPs surveillance points were expanded again in 2013, from 161 to 605 [14], but to eliminate bias from the expansion of surveillance points, in this study we limited analysis to mortality data from the same 161 surveillance points reporting data consistently from 2006 to 2016. Details of the DSPs methodology are reported in previous publications [16].
