Prevalence and Statistics

Prevalence of Asthma in India

As per National Commission on Macroeconomics and Health (NCMH) Background Papers – Burden of Disease in India, it is estimated that there were roughly 2.5 crore cases of asthma in 2001 which may increase by nearly 50% by 2016. Although in terms of percentage India is less than the developed countries, things are rapidly changing. With growing industrialization, change in food habits and lifestyle the prevalence of diseases like asthma is growing.

India has 10% of the world asthmatics which indicates that the asthma population in India is larger than the entire population of several countries. Results from 2 studies done at different time points in the city of Pune have shown that the prevalence of asthma in children has doubled in five years (from 2003-2008). The prevalence of asthma is similar among urban and rural people although there may be regional differences.

Asthma tends to be more common in males in the children but this changes and in the adult population it is slightly more common in females. The disease runs in families but environemental exposure to certain factors is needed for its development. The commonest factor in India is probable the dust mite to whom people develop an allergy and in predisposed individuals asthma develops. Others include cockroaches, pollen, cigarette smoke etc.
