| Summary: | We conducted a cohort study to investigate the association between exposure to three different levels of outdoor air pollution and incidence of respiratory symptoms in a population with chronic cardiovascular and respiratory disease. We accompanied 756 participants for a period of six months through the maintenance of a daily record of symptoms and clinic visits. The symptoms with highest incidence rates were sneezing and hacking cough. Multivariate analysis showed that incidence of total symptoms was 60% and 74% lower in areas with medium and low levels of pollution compared to areas with high levels of pollution. These results suggest that negative respiratory effects occur at concentrations of particulate matter PM10 > 60ug/m³.<br>Se realizó un estudio de cohorte para investigar si la exposición a tres niveles diferentes de contaminación atmosférica extra-domiciliaria está asociada a la incidencia de síntomas respiratorios en una población con enfermedad cardiovascular o respiratoria crónica. Se siguieron por un periodo de seis meses a 756 participantes con morbilidad, usando calendario diario de síntomas y visitas personales. Los síntomas que tuvieron mayores tasas de incidencia fueron el estornudo y la tos seca. El análisis multivariado mostró que la zona de mayor contaminación estaba asociada con un 60% y 74% más de síntomas respiratorios, comparada con la zona de contaminación media y baja, respectivamente. Estos resultados sugieren que los efectos negativos a nivel respiratorios son vistos con exposiciones por encima de 60µg/m³ de material particulado PM10 en esta población. |
