Abstract
BackgroundChronic obstructive pulmonary disease (COPD) is a heterogeneous disorder that progresses over time, and currently it is the fourth leading cause of death across the globe. The World Health Organization (WHO) predicts that the disease will become the third leading cause of death by 2030. The present study aimed to assess the burden trends of COPD in Iran by estimating the disability-adjusted life years (DALYs) from 1995 to 2015.MethodsData were retrospectively collected as the Global Burden of Disease (GBD) from 1995 to 2015 and published by the Institute for Health Metrics and Evaluation. We applied DALYs, incidence and prevalence rate to report the burden of COPD in Iran. To assess the statistical significance according to trend, the Cochran-Armitage test was applied. Additionally, the t-test was used to analyze the DALYs number by gender and Onaway ANOVA by age groups at a significance level set atP < 0.05.ResultsFrom 1995 to 2015, there were approximately 1.1 million DALYs attributable to COPD in Iran. In both genders and at all ages, the number of DALYs increased significantly from 176,224 in 1995 to 253,618 in 2015. The incidence and prevalence rate were 76.65 and 1491.37 per 100,000 population, respectively in both genders in 2015 in Iran. It is noticeable that the number of deaths during the study years, 1995 to 2015, was 39,064. This study showed that the COPD burden was significantly different by age groups and gender.ConclusionsCOPD is still a public health problem in Iran and has an increasing trend. The majority of DALYs were due to the years of life lost as a result of premature death (YLLs), indicating that prevention and early detection, especially in the age groups of 15 to 70 years, should be considered.

The main purpose of this study was to assess the burden trends of COPD in Iran by estimating the years of life lost due to premature death (YLLs) and the years lived with disability (YLDs) in patients with COPD
In the following, we report noticeable findings from the Global Burden of Disease (GBD) attributed to the burden of COPD in Iran from 1995 to 2015
Summary
Chronic obstructive pulmonary disease (COPD) is a heterogeneous disorder that progresses over time, and currently it is the fourth leading cause of death across the globe. The World Health Organization (WHO) predicts that the disease will become the third leading cause of death by 2030. Chronic obstructive pulmonary disease (COPD) is a heterogeneous disorder that progresses over time, and characterized by airflow limitation that is not fully reversible [1, 2]. COPD has grown dramatically, making it the fourth leading cause of death across the globe. In this regard, the World Health Organization (WHO) predicts that the disease will become the third leading cause of death by 2030 [3]. In Asia, its prevalence was reported 13.5% with a range of 3 to 22.2% [6]
