Multivariate analysis of respiratory disorders in relation to environmental factors
The aim of the study is to analyse the joint effect of biological and chemical air pollutants, as well as meteorological variables, on the hospital admissions of respiratory problems for Szeged, Southern Hungary. The data set used covers a nine-year period (1999-2007). The analysis was performed usi...

| 520 | 3 | |a The aim of the study is to analyse the joint effect of biological and chemical air pollutants, as well as meteorological variables, on the hospital admissions of respiratory problems for Szeged, Southern Hungary. The data set used covers a nine-year period (1999-2007). The analysis was performed using three age categories for the pollen season of Ambrosia and the pollen-free season. Two novel procedures are applied here: factor analysis, including a special transformation and a time-varying multivariate linear regression that makes it possible to determine the rank of importance of the influencing variables in respiratory hospital admissions, and also to compute the relative importance of the parameters affecting respiratory disorders. Both techniques revealed that Ambrosia pollen, O3 and wind speed are important variables that influence hospital admissions. The role of chemical and meteorological parameters vary according to the seasons and the methods. Wind speed is a surprisingly important meteorological variable. | |
