Abstract

OBJECTIVES: Time series studies have shown adverse effects of outdoor air pollution on mortality and hospital admissions in patients with chronic obstructive pulmonary disease (COPD) but panel studies have been inconsistent. This study investigates short-term effects of outdoor nitrogen dioxide, ozone, sulfur dioxide, particulate matter (PM(10)) and black smoke on exacerbations, respiratory symptoms and lung function in 94 patients with COPD in east London. METHODS: Patients were recruited from an outpatient clinic and were asked to complete daily diary cards (median follow-up 518 days) recording exacerbations, symptoms and lung function, and the amount of time spent outdoors. Outdoor air pollution exposure (lag 1 day) was obtained from local background monitoring stations. RESULTS: Symptoms but not lung function showed associations with raised pollution levels. Dyspnoea was significantly associated with PM(10) (increase in odds for an IQR change in pollutant: 13% (95% CI 4% to 23%)) and this association remained after adjustment for other the pollutants measured. An IQR increase in nitrogen dioxide was associated with a 6% (0-13%) increase in the odds of a symptomatic fall in peak flow rate. The corresponding effect sizes for PM(10) and black smoke were 12% (2-25%) and 7% (1-13%), respectively. CONCLUSION: It is concluded that outdoor air pollution is associated with important adverse effects on symptoms in patients with COPD living in London.

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.
