Disease burden of chronic obstructive pulmonary disease in Jiangsu province, 1990–2017

ObjectiveTo analyze the disease burden of chronic obstructive pulmonary disease (COPD) of Jiangsu province from 1990 to 2017, and quantify the attributable risk factors.

MethodsThe estimation for the Global Burden of Disease Study 2017 was used to analyze the change trend of the prevalence rate, mortality rate, disability adjusted life years (DALY) and the premature mortality rate of COPD in residents in Jiangsu, during 1990—2017. Population attributable fractions (PAF) was used to estimate the proportion of different risk factors in causing burden of disease.

ResultsFrom 1990 to 2017, the standardized prevalence rate, standardized mortality rate, standardized DALY rate and premature mortality rate of COPD in Jiangsu showed significant downward trend (P＜0.001),but the standardized prevalence rate in female showed no decrease trend (P＝0.157). After 40 years old, the DALY rate increased rapidly with age. The proportion of years lived with disability in DALY increased in recent years. Smoking had become the first cause of COPD disease burden, the PAF was 40.70%.

ConclusionThe disease burden of COPD is decreasing in Jiangsu. However, the situation is still challenging. It is necessary to pay close attention to middle-aged and elderly people and women, take tobacco control as the key prevention and control measure and strengthen the prevention of disability caused by COPD.
