In a study, researchers reported that COPD prevalence, mortality and disability-adjusted life years rates worldwide were lower in 2019 than they were in 1990. The BMJ.
The authors systematically analyzed data from the 2019 Global Burden of Disease Study for 204 countries and territories between 1990 and 2019. The researchers evaluated data on COPD prevalence, mortality, disability-adjusted life years (DALYs), and potential attributable risk factors.
from 212.3 million Globally reported prevalence of COPD cases In 2019, COPD caused 3.3 million deaths and 74.4 million DALYs. The age-standardized global prevalence of COPD was 2,638.2 per 100,000 population, the mortality rate was 42.5 and the DALY rate was 926.1. These rates were 8.7%, 41.7%, and 39.8% lower than those recorded in 1990, respectively.
In 2019, the highest age-standardized prevalence of COPD was in Denmark (4,299.5 per 100,000 population), followed by Myanmar (3,963.7 per 100,000 population) and Belgium (3,927.7 per 100,000 population). Of the population). Egypt, Georgia, and Nicaragua recorded the largest increases in the age-standard point prevalence of COPD from 1990 to 2019, at 62%, 54.9%, and 51.6%, respectively.
In 2019, Nepal had the highest age-standardized mortality rate (182.5 per 100,000 population) and Japan had the lowest mortality rate (7.4 per 100,000 population).
In 2019, Nepal had the highest age-standardized DALY rate (3,318.4 per 100,000 population) and Barbados had the lowest DALY rate (177.7 per 100,000 population). Global DALYs for COPD increased up to age 85 to 89 years before decreasing with age among men. However, this rate rose to the largest age group of 95 years or older in women. The authors also observed an inverse regional V-shaped association between sociodemographic index and age-standardized DALYs for COPD.
In addition to, The researchers found that smoking (46%), ambient particle pollution (20.7%) and occupational exposure to particulates, gases and vapors (15.6%) were the largest contributors to rates of COPD DALYs.
“Although the point prevalence, mortality, and DALY rates have decreased over the study period, the corresponding numbers are increasing. As the population ages, COPD will continue to be a greater problem in the future,” Said SafariPhD Assistant Professor in the Department of Community Medicine, Department of Epidemiology and Biostatistics and the Tuberculosis and Lung Disease Research Center at Tabriz University of Medical Sciences, Iran, and colleagues wrote. “The reported global, regional and national burden of COPD and its risk factors, can help provide more accurate projections of the burden of disease in the future. This knowledge can guide policy makers in planning control measures and supply services to meet the increasing healthcare demands that disease will create. Chronic obstructive pulmonary disease and co-morbidities.
