Effects of particulate air pollution and ozone on lung function in non-asthmatic children

Information on the long-term effects of different air pollutant levels on lung function is relatively lacking in Asia and still inconclusive in the world. Age differential effects of air pollution are not known. To assess the acute and subchronic effects of ambient air pollution on lung function and...

Description
Summary:Information on the long-term effects of different air pollutant levels on lung function is relatively lacking in Asia and still inconclusive in the world. Age differential effects of air pollution are not known. To assess the acute and subchronic effects of ambient air pollution on lung function and compared among children of different ages. From April to May 2011, a nationwide study was conducted on schoolchildren aged 6–15 years in 44 schools of 24 districts in Taiwan. Spirograms were obtained from 1494 non-asthmatic children. Air pollution data were retrieved from air monitoring stations within one kilometre of the schools. Using three-level hierarchical linear models, individual lung function was fitted to air pollution, with adjustments for demographics, indoor exposures, outdoor activity, and districts. Lung function changes per inter-quartile increase of the past two-months average levels of particulate matter
