ABSTRACT
Background: Around 2.6 billion people cook their food using biomass fuel (BMF), kerosene oil, and coal fuel, by which each year, 4 million people die prematurely from household air pollution or by this inefficient cooking practices. So, this study was planned to measure the effect of interventions of cooking fuel (BMF to LPG) to reduce the indoor air pollution in asthmatic children of rural India. Methods: Prospective observational study was done by door-to-door survey, among school-age children. Households of asthmatic children were encouraged to change their cooking fuel to more secure and were followed up for a period of 9 months. The intervention was in the form of a change of cooking fuel (from BMF to LPG) and proper education. The levels of indoor pollutants (PM10, PM2.5, and PM1) were measured before and after 3 months of follow-up. Result: A total of 56 asthmatic children from 42 households were followed-up for the following 9 months at every 3 months visit. The mean age was 9.27 ± 3.94 years with an equivalent sex ratio. There was at least one smoker in 73.81% of households of asthmatic children. Nearly, 45% of children were living in 101–500 square yard area and 67.86% with the inhabitation of ? 3/room. The level of all particulate matter decreased significantly at 3 months (p < 0.05). At 3, 6, 9 months of follow-up, respiratory symptoms and morbidity significantly diminished. Conclusion: The change in cooking fuel to more secure was found to be one of the factors decreasing indoor pollutants and respiratory symptoms/morbidity among asthmatic children in rural areas.
