Surveillance for death causes in residents in Sichuan, 2014–2018

ObjectiveTo understand the death level and death cause rank in residents in Sichuan province from 2014 to 2018 and provide evidence for the further prevention and control of diseases.

MethodsThe death data in 31 national cause-of-death surveillance areas in Sichuan from 2014 to 2018 were obtained from “China Disease Prevention and Control Information System- Death Reporting Information System”. International Classification of Diseases 10^th Edition (ICD-10) was used for death data coding. Age specific and standardized mortality rates were calculated with software SAS9.4.

ResultsFrom 2014 to 2018, the mortality rates in residents in Sichuan were 677.93/100 000, 694.56/100 000, 702.67/100 000, 705.29/100 000 and 703.41/100 000, respectively, and the standardized mortality rates were 555.26/100 000, 562.55/100 000, 529.57/100 000, 531.39/100 000, and 502.10 / 100 000, showing a downward trend. The top 3 death causes were cardiovascular diseases, malignant tumors and respiratory diseases. The top 3 death causes of cardiovascular diseases were cerebrovascular disease, ischemic heart disease, hypertension heart disease and/or kidney disease. The standardized mortality rate of cerebrovascular disease showed a downward trend, and the mortality rate of ischemic heart disease showed an upward trend. The top 3 death causes of malignant tumors were lung cancer, liver cancer and esophageal cancer, their mortality rates showed downward trends, but the mortality rate of pancreatic cancer showed an upward trend. The main death causes of respiratory diseases were chronic obstructive pulmonary disease (COPD) and lower respiratory tract infections, but the standardized mortality rate of COPD showed a downward trend.

ConclusionIn Sichuan, the mortality rate of ischemic heart disease increased significantly. The mortality rate of COPD declined, but it was higher than the national average and ranked ahead. The mortality rate of malignant tumors decreased, but it was higher than the national average. The mortality rate of pancreatic cancer showed an upward trend, to which close attention should be paid.
