The trend of coronary heart disease mortality and disease burden among rural area of Liaoning Province from 2009 to 2015

Objective To explore the trend of coronary heart disease(CHD) mortality and disease burden among Zhangwu and Fengcheng rural areas of Liaoning Province. Methods The all-cause mortality data and the demographic data of Zhangwu and Fengcheng areas in Liaoning Province from 2009 to 2015 were collected. Mortality, age standardized mortality, years of life lost (YLLs), YLL rate, age standardized YLL rate, average years of life lost (AYLLs), age standardized AYLLs and the change of all indexes with year were calculated. Results The maximum value of mortality was 159.34 per 100 000 among rural area of Liaoning Province in 2015. The mortality of CHD was positively correlated with time at a speed of 5.51% (r_s=0.964, P<0.001). YLLs for male and population were positively correlated with time and increased with years at a speed of 5.15% and 4.25% respectively (all P<0.05), but age standardized YLL rate and AYLLs for female were negatively correlated with time and decreased with years at a speed of 5.66% and 1.65% respectively (all P<0.05). Conclusions There was a growing tendency of the mortality and YLL rate of CHD among rural areas of Liaoning from 2009 to 2015, and it brought burdens to people there. It is necessary to carry out health education about CHD and take further measures to prevent CHD.
