Outline
To assess the impact of environmental factors on the chronic respiratory disease (CRD) burden among the Chinese population during 1990—2021, providing scientific evidence for formulating targeted prevention strategies and clinical interventions.
Based on the data of the Global Burden of Disease Study 2021 (GBD 2021), this study adopted descriptive epidemiological methods to analyze the disease burden indicators of chronic respiratory diseases (CRD). Further, the Joinpoint regression model was used to analyze the temporal trend changes of disease burden, and the Age-Period-Cohort (APC) model was constructed to systematically evaluate the impact of environmental risk factors on the disease burden of CRD.
Both the CRD-standardised mortality rate and the standardised DALY rate showed a decreasing trend over the period (P<0.05). As of 2021, outdoor particulate matter has become the primary contributor to the burden of chronic respiratory disease in China. The impact of environmental factors on the disease burden of CRD in China increased with age, with those aged 80 years or older being the most severely affected. Cohort analyses showed that people born in 1912—1951 were more affected by environmental factors, especially indoor air pollution and ambient particulate matter.
The long-term impact of environmental factors on the disease burden of CRD among Chinese residents still cannot be ignored. It is necessary to further strengthen environmental monitoring, formulate and implement stricter environmental standards, especially in controlling outdoor air pollution.
