However, HIV\/AIDS and sexually transmitted infections had negative effects on changes in LE (\u22120.03 years, \u22120.29%) and HALE (\u22120.05 years, \u22120.57%). Lung cancer and ischemic heart disease caused the biggest reduction in LE (\u22120.14 years, \u22121.33%) and HALE (\u22120.42 years, \u22124.82%). Also, cardiovascular diseases (\u22120.08 years, \u22120.92%), neurological disorders (\u22120.08 years, \u22120.92%), diabetes and kidney diseases (\u22120.06 years, \u22120.69%), and transport injuries (\u22120.06 years, \u22120.69%) had main negative disability effects in HALE. Moreover, life expectancy lived with disability (LED) increased by 1.78 years, mainly attributed to respiratory infections and tuberculosis (1.04 years, 58.43%) and maternal and neonatal disorders (0.78 years, 43.82%).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The LE and HALE in China have grown rapidly over the past few decades, mainly attributed to NCDs. It is necessary to further reduce the negative mortality effect of HIV\/AIDS, lung cancer, colon and rectum cancer, pancreatic cancer, and ischemic heart disease and the negative disability effect of stroke, diabetes mellitus, and road injuries. In addition, the signs of disparities in mortality and disability of different sexes and ages call for targeted and precise interventions for key groups such as males and the elderly. According to the decomposition results, we may better determine the key objects of health policies that take into account substantial cause-specific variations to facilitate the realization of
