Air pollution and respiratory health in Mexico City.
To determine the effect of air pollution in Mexico City on respiratory health, patient visits for upper respiratory tract infections were monitored in five clinics.
Levels of ozone, nitrogen dioxide, carbon monoxide, and sulfur dioxide, and climatological variables were collected.
Correlations of filtered data revealed an association between NO2 and O3 with an increase in visits to clinics because of respiratory problems.
Autoregressive analysis indicated that pollutant levels/respiratory visits associations remained significant even after simultaneous inclusion of temperature, suggesting that air pollution was associated with 10 to 16% of the clinic visits.
The relative risk indicated that high levels of O3 and NO2 could increase the total number of clinic visits to between 19 and 43% above average.
The other pollutants and the control group did not demonstrate significant associations.
