Graphical chain models provide a suitable tool for analysing a data set co-ncerning a study on the relationships between athmospheric pollutants and respiratory simptoms in children, taking into account socio-economic and individual risk factors. A questionnaire has been distributed to the parents of 9847 children attending primary schools located in different areas for which measures of air pollution were available (year average of the daily concentration of Particulate and Nitrogen Oxide, NO, mg/m3). Graphical chain models allow to decompose the problem into a series of multivariate regressions, showing important results. Among others, we found that while cough and phlegma depend heavily on smoking habits of the parents, asthma attacks appear associated with higher concentration of NO.

Abstract
Graphical chain models provide a suitable tool for analysing a data set co-ncerning a study on the relationships between athmospheric pollutants and respiratory simptoms in children, taking into account socio-economic and individual risk factors. A questionnaire has been distributed to the parents of 9847 children attending primary schools located in different areas for which measures of air pollution were available (year average of the daily concentration of Particulate and Nitrogen Oxide, NO, mg/m3). Graphical chain models allow to decompose the problem into a series of multivariate regressions, showing important results. Among others, we found that while cough and phlegma depend heavily on smoking habits of the parents, asthma attacks appear associated with higher concentration of NO.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
