Chronic respiratory diseases pose a major public health problem, with an estimated 3.9 million deaths in 2017, accounting for 7% of all deaths worldwide.

Previous analyses of death and loss of health due to chronic respiratory diseases were based on limited data or confined to local areas.

To try and plug this knowledge gap, researchers in China used data from the Global Burden of Disease Study 2017 to describe trends in mortality and disability adjusted life years (DALYs) - a combined measure of quantity and quality of life—due to chronic respiratory diseases, by age and sex, across the world during 1990-2017.

Between 1990 and 2017, the number of deaths due to chronic respiratory diseases increased by 18%, from 3.32 million in 1990 to 3.91 million in 2017.

The number of deaths increased with age and rose sharply in those aged 70 and older, a burden that is likely to increase as the worldwide population ages, suggest the authors.

During the 27 year study period, rates of death and disability ranked according to age (known as the age standardised mortality rate) decreased, particularly in men.

Smoking was the leading risk factor for deaths and disability due to COPD and asthma. In 2017, smoking accounted for 1.4 million deaths and 33 million DALYs, particularly in poorer regions, indicating an urgent need to improve tobacco control in developing countries, say the authors.

Pollution from airborne particulate matter was the next most important risk factor for COPD, with one million deaths and 25 million DALYs.

A high body mass index has also accounted for the most deaths from asthma since 2013, particularly in women, and has contributed the most to DALYs since 2003, add the authors.
