Global Asthma Network (GAN) Study Prevalence of Asthma in India

Agency : Asthma Centre, Jaipur supported by CIPLA Foundation

The Global Asthma Network (GAN) was established in 2012 to identify and address the problem of asthma which is an important Non-Communicable Disease (NCD) globally. GAN evolved from the International Study of Asthma and Allergies in Childhood (ISAAC) and the International Union Against Tuberculosis and Lung Disease (The Union), two organizations dedicated to help countries identify and address this important NCD for more than two decades, and from the Global Asthma Report 2011.

The mission is to prevent asthma and improve asthma care globally, with a focus on low and middle-income countries. The network will achieve this through enhanced surveillance, research, capacity building, and access to effective asthma care including quality-assured essential medicines. The primary aim of the study was to obtain internationally comparable estimates of the prevalence of symptoms of asthma, rhinoconjunctivitis and eczema amongst school children in India and gain insight into the direction and magnitude of change in the prevalence of conditions. This study will also gave us an idea about current data on status of asthma management and environmental factors associated with asthma in our country

The Collaborating centres comprised of one Principal Investigator (PI) for children and one Principal Investigator for adults (parents of corresponding children). For the GAN-ISAAC India study of 2017-18; there were 9 collaborating centres across India namely: Jaipur, New Delhi, Kolkata, Kottayam, Lucknow, Pune, Chandigarh, Mysore and Bikaner.

The population of interest was school children in the age group of 6-7 years and 13-14 years and their parent(s) (both mother and father)/guardian(s) within a given geographical area. Sampling of each age group was done separately. For this study, 3,000 children from each age group and 6,000 parents/guardians were included from each centre. Thus, in total a sample size of 1,62,000 subjects were included (27,000 six to seven-year-old, 27,000 thirteen to fourteen-year-old and 1,08,000 parents/guardians).
