Second Hand Smoke Exposure among Children in Indian Homes: Findings from the Global Adult Tobacco Survey

Children are vulnerable to second hand smoke (SHS) exposure because of limited control over their indoor environment, especially at homes. This study determines the magnitude, patterns and determinants of SHS exposure in the home among children in India. Data collected under the Global Adult Tobacco Survey (GATS) data, a household survey of adults >= 15 years of age during 2016-2017 conducted in India were analyzed to estimate the proportion of children exposed to SHS in their homes. GATS estimates and national census population projections for 2020 were also used to estimate the number of children exposed to SHS in the homes. Nearly half (46.5%) of the children <15 years of age were exposed to SHS in their homes in India which extrapolates to nearly an estimated 170 million. Children living in rural households, north-east and central regions and households with an adult smoker were more likely to be exposed to SHS. SHS exposure among children in home is high in India which calls for adoption of voluntary smoke-free homes initiative and promoting cessation among smokers.
