Trend analysis of the burden of ischemic heart disease in China, 1990 to 2015 / 中华预防医学杂志

ABSTRACT

Objective@#The objective of this study is to analyze the trend of burden of ischemic heart disease (IHD) in China between 1990 and 2015.@*Methods@#Data were collected from the results of 2015 Global Burden of Disease Study. We arranged and analyzed the mortality and disability-adjusted life year (DALY) for IHD by sexes, ages and provinces (excluding Taiwan, China) in China between 1990 and 2015. The age-standardized rates were determined using the average world population age structure in the period of 2010-2035 as a reference, and the changes of the related indicators were calculated.@*Results@#In 2015, IHD caused 1 461 thousand deaths, and its age-standardized death rate was 114.8 per 100 000. Number of DALYs from IHD were 25 765 thousand in 2015, with the age-standardized DALY rate at 1 760.2 per 100 000. From 1990 to 2015, the age-standardized death rate for IHD in China increased by 13.3% but age-standardized DALY rate decreased by 3.9%. Number of IHD DALYs among male (16 664 thousand) was higher than it among female (9 101 thousand) in China in 2015, and 83.5% of total DALYs from IHD occurred among people aged over 50 years old. Province with highest age-standardized death rate was Heilongjiang, with rate at 187.4 per 100 000 in 2015. Qinghai (54.0%) increased most and Macao (-52.3%) decreased most from 1990 to 2015. Province with highest age-standardized DALY rate was Xinjiang, with rate at 3 040.8 per 100 000 in 2015. Qinghai (33.2%) increased most while Macao (-59.0%) decreased most between 1990 and 2015.@*Conclusion@#Burden of IHD in China increased remarkably from 1990 to 2015, especially among males and people aged over 50 years old. The differences among provinces were obvious.
