[Analysis of correlation of community management index of essential hypertension and type 2 diabetes with probability of premature mortality caused by major non-communicable diseases in Zhejiang Province].

To evaluate the correlation of community management index of essential hypertension and type 2 diabetes with the probability of premature mortality of major chronic diseases. From 2016 to 2018, the management of essential hypertension and type 2 diabetes were obtained from annual report of comprehensive prevention and control of chronic diseases in communities of Zhejiang province. The death data of chronic diseases were obtained from Information Management System of Chronic Diseases of Zhejiang province and annual population data were obtained from Public Security Bureau of Zhejiang Province. The management of essential hypertension and type 2 diabetes in communities of Zhejiang Province from 2016 to 2018 was described. The death status of major chronic diseases, including cardiovascular diseases, malignant tumors, diabetes and chronic respiratory diseases, in the same period was also described. Spearman correlation analysis and linear regression model were used to explore the correlation of community management of essential hypertension and type 2 diabetes with the probability of premature mortality of major chronic diseases. The number of essential hypertension patients under standardized management, blood pressure control and regular medication increased from 3.127 3, 2.811 5 and 3.569 7 million in 2016 to 3.355 9, 3.151 8 and 4.010 6 million in 2018, respectively. The number of type 2 diabetes patients with standardized management, blood glucose control and regular medication increased from 0.805 5, 0.687 5 and 0.913 4 million in 2016 to 0.912 6, 0.798 7 and 1.064 8 million in 2018, respectively. The standardized mortality rate of chronic diseases decreased from 403.07/100 000 in 2016 to 380.07/100 000 in 2018. The proportion of premature deaths of chronic diseases decreased from 28.39% in 2016 to 26.90% in 2018. The proportion of deaths from major chronic diseases in all chronic diseases decreased from 90.96% in 2016 to 90.69% in 2018.The probability of premature mortality decreased from 10.68% in 2016 to 9.67% in 2018. The spearman correlation analysis showed that the blood pressure control and regular drug use were negatively correlated with the probability of premature death of major chronic diseases ( values were -0.367 and -0.392; values were 0.035 and 0.024). According to the linear regression model analysis, with increase of 100 000 of essential hypertension control cases or regular medication use cases of type 2 diabetes, the probability of premature death of major chronic diseases decreased by 0.47% (95%: 0.39%, 0.54%) or 1.31% (95%: 1.12%, 1.50%), respectively. From 2016 to 2018, the community management of essential hypertension and type 2 diabetes was negatively correlated with probability of premature death of major chronic diseases in Zhejiang province.
