Asthma, COPD led to 3 million deaths worldwide in 2015: Study

New Delhi: Two common chronic respiratory conditions -- asthma and chronic obstructive pulmonary disease (COPD) -- led to over three million deaths worldwide in 2015, a report in a reputed medical journal has said, highlighting that India, along with other three countries, recorded the highest disease burden due to COPD.
According to a Global Burden of Disease study published in the Lancet Respiratory Medicine journal, 3.2 million deaths took place due to COPD while 0.4 million people died of asthma in 2015.
"The disease burden due to COPD in 2015 was highest in Papua New Guinea, India, Lesotho and Nepal, and burden for asthma was highest in Afghanistan, Central African Republic, Fiji, Kiribati, Lesotho, Papua New Guinea and Swaziland," it said.
India recorded 2774.64 prevalent cases of COPD per 100, 000 people (2533-3027.38) and 4021.72 prevalent cases of asthma per 100,000 (3637.41-4,424.58) in 2015, the report said.
The study estimated the number of cases and deaths caused by the two conditions between 1990 and 2015 worldwide. COPD is a group of lung conditions (including emphysema and chronic bronchitis) that cause breathing difficulties. The condition is largely caused by smoking and air pollution.
While overall prevalence and death rates had reduced since 1990, population growth and the ageing population meant that the numbers had increased, it said.
The number of deaths due to COPD increased by 11.6 per cent between 1990 and 2015 (from 2.8 to 3.2 million), and the number of cases increased by 44.2 per cent (from 121 to 174.5 million), the report said.
Comparatively, deaths from asthma reduced by 26.2 per cent (from 0.55 to 0.4 million), but prevalence increased by 12.6 per cent (from 318.2 to 358.2 million) over the same time period, it said.
