Air Pollution and Emergency Room Admissions for Chronic Obstructive Pulmonary Disease: A 5-year Study
Abstract
An association between sulfur dioxide levels in urban air and the daily number of emergency room admissions for chronic obstructive pulmonary disease was previously reported in Barcelona, Spain, for the period 1985-1986. The present study assesses this association over a longer period of time, 1985-1989. This made it possible to carry out separate analyses for the winter and summer seasons and thus to control more adequately for weather and influenza epidemics. An increase of 25 micrograms/m3 in sulfur dioxide (24-hour average) produced adjusted changes of 6% and 9% in emergency room admissions for chronic obstructive pulmonary disease during winter and summer, respectively. For black smoke, a similar change was found during winter, although the change was smaller in summer. The association of each pollutant with chronic obstructive pulmonary disease admissions remained significant after control for the other pollutant. The present findings support the conclusion that current levels of sulfur dioxide and black smoke may have an effect on the respiratory health of susceptible persons.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
