Summary 

The Indian Study on Epidemiology of Asthma, Respiratory Symptoms and Chronic Bronchitis (INSEARCH) was conducted in two phases. Phase II, which took place in 2007-2009, involved a survey conducted across twelve study centers throughout India. A total sample of 169,575 individuals were interviewed as part of this survey; participants were drawn from rural and ruban areas for all centers except at Secunderbad, which only included urban areas. The questionnaire collected information about participants' respiratory symptoms, tobacco use, exposure to secondhand smoke, cooking fuels used in the household, asthma diagnoses, and BCG vaccination history.

Phase I of INSEARCH was conducted in 2004-2005 at four centers across India.
