Abstract：Objective To analyze the trends in diabetes mellitus mortality rates and years of life lost(YLL)across China and its regions from 2008 to 2021,and to assess the burden of diabetes-related deaths.Methods Based on nation-al cause-of-death surveillance data from 2008 to 2021,Excel 2019 and Python 3.9 software were used to collate and ana-lyze the age-standardized mortality rate,age-standardized YLL rate,and estimated annual percentage change(EAPC)for diabetes across different genders,regions,and age groups.Results The standardized mortality rate for diabetes mellitus in China increased from 7.94 per 100 000 in 2008 to 9.12 per 100 000 in 2021,representing a 14.86%rise.From 2008 to 2016,the age-standardized mortality rate was higher in females than in males.However,the rate increased faster among males(EAPC:2.03 for males vs.0.64 for females),leading to higher male mortality from 2017 onward.From 2008 to 2010,females had the highest age-standardized YLL rate.Yet,as the male YLL rate showed sustained growth(EAPC:2.42)while the female rate declined(EAPC:0.11),males exhibited a higher YLL rate than females after 2011.From 2008 to 2021,both the age-standardized mortality rate and YLL rate for diabetes were higher in urban areas compared to rural areas.During 2008-2016,the eastern region had the highest age-standardized mortality rate,and during 2008-2011,the central region had the highest age-standardized YLL rate.However,the western region exhibited the fastest growth in both the mortality rate and YLL rate,gradually becoming the region with the highest age-standardized mortality rate(since 2017)and YLL rate(since 2012).The burden of diabetes-related deaths increased with age,being highest among individ-uals aged 75 and above,with a peak observed in the≥85 age group.Conclusions From 2008 to 2021,diabetes melli-tus-related mortality in China increased substantially.Diabetes mellitus remains a chronic disease requiring prioritized pre-vention and control.Males,the elderly,and populations in rural and western regions face relatively higher mortality risks.
