Insights
Cardiovascular diseases significantly reduce life expectancy (LE) in China, impacting LE by over 8 years. Addressing these major chronic noncommunicable diseases is crucial for public health and longevity.
Area of Science:
- Public Health
- Epidemiology
- Gerontology
Background:
- Chronic noncommunicable diseases (NCDs) pose a significant public health challenge globally and in China.
- Understanding the impact of major NCDs on life expectancy (LE) is vital for targeted health interventions.
Purpose of the Study:
- To quantify the association between four major NCDs (cardiovascular diseases, cancer, respiratory diseases, diabetes) and LE in China for 2019.
- To provide evidence for scientific prevention and treatment strategies for chronic diseases in China.
Main Methods:
- Utilized the Jiang Qing Lang method, recommended by the WHO, to construct abbreviated life and cause-eliminated life tables.
- Calculated LE and cause-eliminated life expectancy (CELE) for Chinese residents in 2019.
Main Results:
- Cardiovascular disease (CVD) removal was associated with the largest LE increase (8.13 years).
- Cancer removal added 2.68 years, respiratory diseases 0.88 years, and diabetes 0.24 years to LE.
- The four major NCDs collectively represent a substantial burden on the health of Chinese residents.
Conclusions:
- CVD is the primary NCD affecting LE in China and should be prioritized for prevention and treatment.
- Health promotion efforts should focus on women and rural populations.
- Promoting self-protection and healthy lifestyles is essential for reducing mortality and improving overall health outcomes.
Abstract:
This study aimed to illustrate the association of four major chronic noncommunicable diseases (cardiovascular diseases, cancer, respiratory diseases, and diabetes) with life expectancy (LE) of Chinese residents in 2019 and to provide an evidence base for the scientific prevention and treatment of chronic diseases in China. The abbreviated life and cause-eliminated life tables were compiled according to the Jiang Qing Lang method recommended by WHO (World Health Organization) to calculate LE and cause-eliminated life expectancy (CELE) in 2019. The disease that had the greatest association with the LE of Chinese residents was cardiovascular disease (CVD), with the LE increasing by 8.13 years after removing CVD deaths. This was followed by cancer (2.68 years), respiratory diseases (0.88 years), and diabetes (0.24 years). The four major chronic noncommunicable diseases (NCDs) were the main diseases affecting the health of Chinese residents. CVD should be prevented and treated as the key disease among the chronic diseases, while women and rural people should be the major focus of health knowledge promotion. All residents should be encouraged to develop a good understanding of self-protection and of how to achieve a healthy lifestyle in order to reduce the occurrence of death and to improve their quality of life and health in general.
