Abstract

The prevalence of chronic obstructive pulmonary disease (COPD) is rising in China, yet population-based evidence on COPD-related mortality risk remains limited. This study examined the association between prevalent COPD and all-cause and cause-specific mortality in a large Chinese cohort. 484,301 adults aged 30 to 79 years who received spirometry at the baseline of the China Kadoorie Biobank Study (2004-2008) were included. COPD was defined as FEV1/ FVC < 0.7. Mortality data were tracked via local death registries and national health insurance systems over a median follow-up period of 16.0 years. Cox proportional hazard models and competing risk regression were used to estimate hazard ratios (HRs) and subdistribution HRs (SHRs), respectively. The COPD group had higher all-cause and cause-specific mortality, with adjusted HR (95%CI) for all-cause mortality of 1.44 (1.41-1.47), and adjusted SHR (95%CI) of 1.09 (1.05-1.13), 1.06 (1.01-1.11), 3.30 (3.12-3.49), 1.45 (1.16-1.81), for circulatory disease, neoplasms, respiratory disease, and infectious disease mortality, respectively. Specifically, young COPD (aged < 50 years) showed a stronger mortality association than those aged ≥ 50 years. Moreover, individuals with preserved ratio impaired spirometry (PRISm) had a 1.4-fold higher risk of all-cause mortality compared with non-COPD participants. COPD is associated with a significantly elevated risk of mortality from all causes, circulatory disease, neoplasms, respiratory disease, and infectious disease in the Chinese population. Additionally, young COPD and those with PRISm faced significant mortality burdens.

中国COPD患者的全因死亡率和病因特异性死亡率:一项16年随访队列研究
慢性阻塞性肺疾病(COPD)在中国的患病率正在上升,但基于人群的COPD相关死亡风险证据仍然有限。本研究在一个大型中国队列中调查了流行COPD与全因和病因特异性死亡率之间的关系。在中国嘉道理生物库研究(2004-2008)基线时接受肺活量测定的484,301名30至79岁的成年人被纳入研究。COPD定义为FEV1/ FVC

期刊介绍: The European Journal of Epidemiology, established in 1985, is a peer-reviewed publication that provides a platform for discussions on epidemiology in its broadest sense. It covers various aspects of epidemiologic research and statistical methods. The journal facilitates communication between researchers, educators, and practitioners in epidemiology, including those in clinical and community medicine. Contributions from diverse fields such as public health, preventive medicine, clinical medicine, health economics, and computational biology and data science, in relation to health and disease, are encouraged. While accepting submissions from all over the world, the journal particularly emphasizes European topics relevant to epidemiology. The published articles consist of empirical research findings, developments in methodology, and opinion pieces.
