Life expectancy and mortality rates of major chronic disease in demonstration area of Tianjin, 2008–2018

ObjectiveTo analyze the life expectancy and mortality rates of major chronic diseases in demonstration area of Tianjin from 2008 to 2018, and evaluate the effects of the establishment of demonstration area for chronic disease prevention and control.

MethodsBased on the data of all-cause deaths of the whole population in Tianjin, we compared the life expectancy and mortality rates of all-cause deaths and major chronic diseases (cardio-cerebrovascular diseases, malignant tumors, diabetes and chronic lower respiratory tract diseases) in residents in demonstration area, non-demonstration area and whole city of Tianjin. The population data were from Tianjin Municipal Public Security Bureau. The crude mortality rates, standardized mortality rate, life expectancy and annual percentage change were analyzed.

ResultsThe people’s life expectancy increased from 81.48 years in 2008 to 82.38 years in 2018 in demonstration area (APC=0.19, P<0.05), and the annual people’s life expectancy was all higher in demonstration area than in non-demonstration area. The crude mortality rates of all-cause deaths showed no change trend in demonstration area, but showed upward trends in both non-demonstration area and whole city. The standardized mortality rates of all-cause deaths showed no change trend in demonstration area, non-demonstration area and whole city after adjustment for standardized population constituent. The crude and standardized mortality rates of acute myocardial infarction, chronic lower respiratory diseases and liver cancer showed more decreases in demonstration area compared with non-demonstration area. The mortality rates of breast cancer in females and diabetes in males showed less increases in demonstration area than in non-demonstration area and whole city. The mortality rate of colorectal cancer showed more increase in demonstration area than in non-demonstration area and whole city.

ConclusionThe establishment of chronic disease prevention and control demonstration area in Tianjin had shown effects. Each demonstration area explored their new models constantly for the prevention and control of chronic diseases, which would benefit the improvement of the prevention, control and management of chronic diseases in Tianjin.
