The study was entitled "The Burden of Chronic Respiratory Disease and its Heterogeneity Across Indian States: A Study of the World Burden of Disease 1990-2016".
On an estimated load of 52 lakh cases of COPD in the 1990s, UP now houses 98.6 patients with COPD lakh. The paper noted that after Rajasthan, UP represented the largest burden of COPD among Indian states.
The study also revealed that UP and Rajasthan also accounted for the highest rates of death and disability adjusted life years (DALYs) due to asthma. A study conducted in 2017 by the Population Health Foundation of India noted that COPD was the leading cause of death in Uttar Pradesh. The Lancet study showed that the leading risk factor for COPD in India in 2016 was air pollution, which accounted for more than half of all COPD-related DALYs. This was followed by smoking, which contributed a quarter to COPD DALY in 2016.
Lung expert and former director of the Patel Chest Institute in New Delhi, Professor Rajendra Prasad said that tiny dust particles in the air could trigger COPD.
"Against a daily requirement of 2 kg of food and 3 liters of water, an adult inhales and expires about 8 liters of air per minute. Of this, only 20% is oxygen. Pollutants affect the quality of lung function, which opens the door to disease, "he said. The study also noted that the high rate of COPD cases is due to relatively late diagnosis and care, even with improved health care in India.
Evidence suggests that COPD is underdiagnosed in India, in part because the diagnosis is based primarily on symptoms rather than spirometry (diagnostic test). In addition, symptomatic people are often late in seeking care because of insufficient awareness of COPD.
