Attributable risk of cardiovascular mortality associated with different glycometabolic status among different regions in China

Objective To estimate the attributable risk of deaths and disease burden of glycometabolic status among different regions in China.Methods Data of this study were obtained from the China Hypertension Survey(CHS)in 2012 to 2015 and National Disease Surveillance Points System in 2013.The 22702 participants aged 35 or order without self-reported medical history of cardiovascular disease(CVD)were enrolled from CHS,and CVD mortality were followed up in 2018 to 2019.Cox regression was applied to estimate the relationship between glycometabolic status and mortality.Population attributable fraction(PAF)was used to assess the burden of CVD mortality due to different glycometabolic status.Results During the follow-up period,479 CVD deaths were ascertained.The HRs(95%CI)of CVD mortality for prediabetes and diabetes were 1.37(1.04-1.80)and 1.36(1.06-1.75),respectively,compared with those with normal blood glucose.In 2013,the PAFs of CVD mortality associated with prediabetes and diabetes were 2.48%(95%CI:2.31%-2.66%)and 2.96%(95%CI:2.79%-3.13%),respectively.The number of CVD deaths attributed to prediabetes and diabetes were 119900 and 139700,respectively.Besides,significant regional and provincial differences of disease burden to glycometabolic status were observed.The PAF of CVD mortality attributed to diabetes was highest in the east[3.73%(95%CI:3.44%-4.04%)],followed by the west[2.62%(95%CI:2.24%-3.01%)],and the lowest in the middle[2.42%(95%CI:2.16%-2.68%)].Conclusions The CVD burden caused by prediabetes and diabetes is relatively heavy and varies by region and province,corresponding measure should be made to reduce the disease burden caused by prediabetes and diabetes.
