Chronic obstructive pulmonary disease (COPD), one of the most common chronic respiratory diseases, was responsible for 3.2 million deaths in the world in 2015. In India, it is the second most common cause of death (9.7%). With 64 deaths per 100,000 population, it stands second in India, just after ischemic heart disease (132 deaths per 100,000), as the common causes of mortality. To mitigate the burden, COPD was included under the National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases, and Stroke. With an emphasis on health promotion and screening for early diagnosis, the Programme ensures provision of treatment and timely referral through noncommunicable disease clinics.
As evident from a recent report, Rajasthan (111/100,000) recorded six times higher mortality than Nagaland (18/100,000). Notably, most of the states with high COPD burden are located in North India. COPD has often correlated with air pollution caused due to stubble burning. Delhi recorded low mortality (22/100,000), despite being one of the most polluted cities in the world and getting a big share of stubble-burning pollutants from neighboring states, probably because of quality medical treatments available there and presence of least agricultural fields. According to the available data, only 30% of land in Delhi is being cultivated, making direct exposure less likely. Why disparity exists among different states of India is a matter of further analysis. Among different factors, smoking, despite thought to be the main cause of COPD, was earlier demonstrated to have no relation with COPD deaths. Previous researches indicated that secondhand smoking increased the risk of COPD mortality. Biased or missed reporting may be another cause. Unlike western countries, the presence of smoking is not always found here as an associate of COPD.
Exposure to biomass also plays a crucial role in causing death in such patients., The government is encouraging the use of clean fuel for cooking by the population through Ujjwala Scheme. This could be hoped that the deadly exposure to biomass fuel could be minimized with the success of the Scheme. Promoting clean fuel would ensure indoor air quality; however, without efforts to bring outdoor air pollution under control, the problem of COPD could never be tamed.
The role of poverty in COPD death was documented earlier. The frequency of COPD rises once gross national income per capita falls below USD 15,000. Multisectoral efforts should target poverty alleviation and subsequent drop in tobacco consumption. For future strategy, the focus should be on the states having higher usage of tobacco and/or lower per capita income.
