González Biología Spain Mortality and morbidity multiple linear regression analysis pollutants and meteorological variables We examined the possible relationships between pollutant concentrations and mortality at seven differentlocations of Castilla-León, Spain, and the relationships between such concentration levels and emergencyadmissions (morbidity) at four hospitals in the region, taking into account the possible masking effect ofother atmospheric variables. The study was based on daily mortality and morbidity data from 1995 to 1997(ICD-9 codes: 390-459 cardiovascular; 460-519 respiratory; 520-579 digestive causes); moreover, data formeteorological variables (air temperature, relative humidity, solar radiation, atmospheric pressure and windvelocity) and air pollution data (SO2, O3, NO, NO2 and CO) were used. A minimum set of weather and pollutantpredictors was selected using forward inclusion stepwise linear regression methods and these were used toproduce a multivariate model of the different causes of mortality and morbidity. For the whole period, themortality attributable to cardiovascular causes had an incidence higher than the mortality due to respiratoryand digestive causes. The frequency distributions corresponding to the different diseases as classified byages revealed that the population older than 69 is the most affected, the proportion of cardiovascular diseaserelateddeaths in this age sector being 7-fold higher than for the rest of the groups. Mortality and morbiditydue to respiratory and cardiovascular-related diseases showed a high correlation coefficient with temperature,solar radiation and ozone, and in general significant correlations were also seen with SO2. 2006 artículo científico 0187-6236 https://www.redalyc.org/articulo.oa?id=56519103 en http://www.redalyc.org/revista.oa?id=565 Atmósfera application/pdf Universidad Nacional Autónoma de México Atmósfera (México) Num.1 Vol.19 |
