Trend on mortalities in all-cause and chronic non-communicable diseases among the labor force population in China, 2007-2016

Abstract

Objective: To analyze the trends on mortalities of all-cause and deaths caused by chronic and non-communicable diseases (NCDs) among Chinese labor force population during 2007 to 2016. Methods: Data on cause-of-death that collected from the National Mortality Surveillance System was used to analyze the age and area-related specific crude mortality rates, age-standardized mortality rates and component ratios of NCDs, among the Chinese labor force population, during 2007 to 2016. Trend of crude mortality rates and mortality component ratios of the three major diseases (infectious diseases, maternal and infant diseases, nutritional deficiency diseases; NCDs; injuries) were analyzed. Age-standardized mortality of cancer, COPD, cardiovascular and cerebrovascular diseases were also analyzed by gender. Age-standardized mortality was calculated based on the Year 2010 Population Census of China. Joinpoint regression model was used to obtain annual percentage change and 95%CI was set for assessing the trend. Results: In 2016, the age-standardized all-cause mortality rate was 217.23 per 100 000 among the Chinese labor force population, but decreased by -2.8% (95%CI: -3.8%- -1.7%) annually from 2007 to 2016. The gap between different gender and regions gradually narrowed. The proportion of deaths caused by NCDs increased annually by 0.8% (95%CI: 0.7%-0.9%). The age-standardized mortality rate of NCDs appeared as 171.89/100 000, among the Chinese labor force population in 2016, showing a downward trend by -2.4% (95%CI:-3.3% - -1.4%). However, in females, there appeared the greatest decrease, with an average annual change of -3.3% (95%CI:-4.0% - -2.5%). Diseases as cancer, COPD, cardiovascular and cerebrovascular diseases all showed downward trends in the whole country, with an average range of -2.0% (95%CI: -2.6%--1.3%), -8.0% (95%CI: -8.9% - -7.1%), -1.5% (95%CI: -2.9% - -0.1%), -2.3% (95%CI: -2.8% - -1.8%) in a ten-year period, respectively. Conclusion: All-cause and age-standardized mortality rates caused by NCDs among Chinese labor force population were decreasing during 2007 to 2016. However, the constituent ratios appeared increasing, year by year. Close attention needs to be paid on NCDs which affecting the health of the labor force population in China.
